Ductless AC Systems College Station

Ductless AC Systems Installation Guide

Some residential applications just don’t fit the normal central air conditioning system applications or home additions that will not connect well to an existing system. Ductless AC Systems College Station are a great option and here is why:

Older homes without central air conditioning that have been making do with room window units.
Room additions or garage remodels that make an existing system undersized.
Trouble spots at the end of long duct runs that are always uncomfortable.

A mini-split ductless air conditioning system might be a perfect solution for problem spaces.

Compare Central Air to Ductless AC Systems

Central air conditioners are the primary residential air conditioner application across the nation. They consist of:

An outdoor condenser unit connected to the indoor cabinet by tubes containing refrigerant.
Ductwork running from the indoor cabinet to each room in the home.
Return air ducts that bring the warm air back to the central cabinet.

This system removes heat (cooling the indoor space), cleans and moves the air, and removes humidity.

Ductless AC Systems are relatively new to the US housing market. Ductless AC Systems consist of:

An outdoor condenser unit connected directly to rooms and spaces being cooled by tubes containing refrigerant.
Small, room-sized air handlers, and no ducts.

This system also removes heat, cleans and moves the air, and removes humidity.

The two major differences are the mini-split system has no central cabinet and no duct system. If central air conditioning was installed in a home from the beginning, replacing the air conditioner and furnace with new versions would make economic sense in most situations.

But if a home started without a central air system, the mini-split ductless system saves the expense of making room for a central cabinet and demolition to install ductwork behind finished walls. A problem hotspot or remodel might be inaccessible to an existing central air system. Mini-split systems might be a good alternative.

Here is what a mini-split installation might look like in your home.

Locating the Condenser Unit for Ductless AC Systems

The outdoor portion of the air conditioner is called a condenser unit. A major function is the cooling of refrigerant after it picks up heat from inside the home, so it needs to have adequate air movement on all sides.

The condenser may be installed on a concrete pad, elevated to a shelf on the side of the home, or as a rooftop unit. In any of these applications, 2 to 3 feet of space needs to surround the unit.
The condenser should not be placed in direct sunlight if possible, since this reduces air conditioner efficiency.
The installation should be central to the area being served, keeping the refrigerant tubes under 150 feet if possible. Beyond this distance, refrigerant efficiency is lost.

Locating the Air Handler Units for Ductless AC Systems

The air handler must be installed on an exterior wall, as close to the condenser unit as possible. An opening is made in the wall for refrigerant tubes and drain lines (carrying the humidity removed from the air outside).
The air handler can be placed at any height, from floor to ceiling, but placement at about 5 to 6 feet from the floor is advantageous. The blower can more easily distribute the fresh, cool air throughout the room from this height. The air handler will also need to be accessible for maintenance and air filter replacement.
Some wall features may hamper adequate performance, such as large windows or heat-producing appliances—hot lights or large television screens. Install the air handler as far away from these features as possible.
Each air handler will have a separate thermostat, which must be placed out of direct sunlight on an interior wall. This, too, must be placed away from heat-producing appliances.

Mini-split ductless air conditioning systems need the same regular professional maintenance and air filter changes as central air conditioning systems.

AC Maintenance College Station

AC Maintenance College Station Tips for Homeowners

Annual preventative maintenance for your air conditioner system serves the same purpose as an oil/filter change and tire rotation for your vehicle. Without these services, dirty pollutants would interfere with the function, causing energy inefficiency and poor performance. Ignoring tire maintenance leads to uneven wear and shortens usefulness.

Regular AC maintenance College Station of your air conditioner is beneficial beyond poor performance and premature failure (although these are significant benefits.)

A new air conditioner system will run at peak performance for a while, but time and contaminants “gum up the works.” Efficiency begins to decline since the system will work harder to keep the home cool and comfortable. Increased workload results in increased energy costs and higher bills. Maintenance helps restore the system closer to the original performance standard.
Poor performance will be noticeable by inconsistent or poor comfort levels in the home. The heat and humidity can both be higher than is normally comfortable. This often results in family members lowering the temperature setting, putting stress on the system without the desired results.
A poorly maintained system is more likely to experience unexpected problems and failure. Initially, the repairs might not be expensive, but the discomfort and inconvenience of being without air conditioning for a few days or an entire week is quite unpleasant.

Regular AC maintenance can avoid many of these problems.

What needs to be maintained?

The filter needs to be changed regularly, at least once every three months. It is surprising how many homeowners neglect this simple task.
The thermostat is the ON/OFF switch for the air conditioner. It is battery-powered, and we replace the batteries. Occasionally, the thermostat needs to be tested and recalibrated.
The AC system has a small computer—a circuit board—and maintenance tasks include troubleshooting the board for errors and faults.
The blower motor has the only moving parts in the whole system. The blower assembly will be tested, cleaned, lubricated, and the belt replaced, as needed.
The several sensors, switches, and control mechanisms needed to be tested for weakness and failure. An electrical failure tends to put stress on other parts until a cascade of failures occurs; testing catches problems early. Visual inspections will uncover potential loose wiring connections.
The refrigerant pressure will be tested. Air conditioning systems use a refrigerant, which changes between liquid and gas depending on the temperature. The refrigerant is in a closed loop and must be kept at a very particular pressure; when the pressure drops, it ceases to cool properly.
Inside the central air cabinet is an A-shaped coil of tubes. The refrigerant is cold while in these tubes, so humidity in the air condenses and drops to a drain pan below. This area is thoroughly cleaned to make sure the water does not leak onto the floor.
The motor that compresses the refrigerant is located outdoors in the condenser unit. It is crucial to the system, so its performance will be thoroughly checked.
The exterior of the condenser unit is a hollow network of cooling tubes with a huge fan inside. The fan pulls air through the tubes to cool the hot refrigerant. It also pulls in dust, pollen, and anything else that gets too close. Maintenance includes thoroughly cleaning the condenser coil to ensure the fan can cool the gas in the tubes.
Not all the ductwork will be visible, but a technician will make a visual inspection of everything within sight, including interior vents.
After all the components are tested, inspected, and tweaked, maintenance will be finalized through a performance test. This includes measuring temperature changes during the cooling cycle.

Cut Your AC Repair Costs This Summer

College Station AC Repair – How to Reduce Potential AC Repair Costs

Yes, indeed, it is summertime. If you ever forget, just step outside for a few minutes and you will notice the heat and humidity immediately. For the next few months, your air conditioner and you will fight a battle, with heat, humidity, and solar gain. You heard that right—you contribute to reducing summertime discomfort. Here is how:

Enjoy the sun, but enjoy it early and late, not during the heat of the day.

Locate the south side of the house—it is probably quite evident.
The windows and glass doors on the south side should have blinds and/or drapes that block the sun and heat.
Open these window treatments until about 9 am and close them until after 4 pm.

The heat that enters your home directly from sunlight is called “solar gain.” Leaving these window treatments open can raise the temperature in the home by 10 degrees, requiring the thermostat to call for cooling several times more per day.

Stay dry inside as much as possible.

Hot, steamy showers are not as beneficial during the summer months.
Use bathroom exhaust fans during and immediately after a shower, but don’t run them for long. As the fan pushes air out, it is drawing humid air in at the same time.

A healthy relative humidity indoors is between 40% and 60% while the outdoor humidity rises above 90%. Keep windows and doors closed as much as possible when the humidity is high.

Mix the air with ceiling fans. From elementary school science, we know hot air rises, which is also true indoors.

Indoor air tends to layer, with the hot air staying high and the cooler air dropping low.
Humid air also tends to layer, with heavy, moist air dropping low and dryer air rising.
Ceiling fans blend the air, allowing the air conditioner to cool and dehumidify all of the air in the home.

Change the ceiling fan rotation to counterclockwise and set it to slow. This pushes air down gently and mixes it thoroughly. It is a good idea to keep ceiling fans running on low, even when the house is unoccupied since the ceiling fan uses very little energy.

Learn to program the thermostat for enhanced comfort and energy savings.

Most thermostats are programmable, all but the very old ones. It only takes a few minutes to learn how to schedule temperature changes.
The body temperature drops while we sleep, so the temp could be raised while the family sleeps with no loss in comfort.
It is a good savings practice to raise the temperature during the day if the home is unoccupied.
Experiment in a temperature range of between 5 and 8 degrees. Program normal cooling about 30 minutes before everyone arises or arrives home.

Eight hours per day of this range difference will be noticeable on the energy bill.

Take care of the air conditioner inside and out with annual maintenance cleaning and inspection. Three major components provide air conditioning function, and they all need service.

The condenser, the outdoor portion of the air conditioner, collects dust, grass clippings, and leaves, which need to be cleaned away.
The evaporator coil on the inside collects moisture from the air and lets it fall into a drain. Ignoring this part can leave a leaky mess.
The blower motor draws a tremendous volume of air from the house and recirculates it back into the house. This is the only moving part of the system and needs to be serviced regularly.

Of course, you also have the responsibility for changing the air filter regularly—every three months is good for most homes.

Simple Steps to Improve AC Efficiency

Improving Your AC Efficiency with These Simple Tasks

For the next 4 or 5 months, air conditioners will run at regular intervals to make homes safe and comfortable. On most days, the system will function adequately. But there will be days of extreme heat and humidity that might lead one to wish that the air conditioner cooling output was a little better or a little faster. If the system is well-maintained and performing as designed, there might be human actions that impact the function of the air conditioner system. Consider these actions.

AC Efficiency: Understanding Air Volume

Air conditioning requires massive amounts of air movement, both inside and outside. For this discussion, we will only consider the air movement inside.

For every ton of air conditioning, a blower motor must move 400 cubic feet per minute (CFM); a three-ton unit will need to move 1200 CFM. That means that every two minutes, statistically, the entire volume of a 2400-square-foot home will move through the evaporator chamber and come into contact with cold coils before returning to the home. Anything that slows or blocks the free movement of air hinders the cooling process.

AC Efficiency: Potential Hindrances of Air Movement

Air Filters. The air moves rapidly through an air filter, usually less than 2’ square. Dust and airborne pollutants collect on the filter and after a few months, the collection will begin to slow air movement. The filter should be changed at least every three months.
Return Vents. Each story of a home should have at least one return vent installed about 6 feet up on the wall. The blower motor pulls hot air from the home through these vents and directly into the cooling process. Of course, if anything blocks these vents, it will severely restrict air movement. Keep drapes and wall hangings 6 to 12 inches away from these vents.
Supply vents. The blower motor delivers cool air to the home via floor or low-wall-mounted supply vents. If furniture, rugs, or clothes cover a supply vent, not only does it prevent cool air from entering the space, but the static air pressure in the vents increases. That allows cool air to find even the smallest flaw in the ductwork, pushing the valuable cooled air outdoors. Keep obstacles at least 6 to 12 inches away from supply vents.

AC Efficiency: The Duct Network

A system of ducts carries a massive volume of air from the home to the evaporator chamber and back to the home.

The air moving through the ductwork is under pressure. Air will be pushed out of any leak or opening in the network, usually into the attic, garage, or crawlspace under the home.
Any ductwork installed in unconditioned space should be insulated to prevent the air inside from heating.
Even insulated ducts that carry air to the far reaches of a home will gain heat on its journey.
Dust and particles will eventually collect inside the ducts. They should be cleaned as needed; a healthy recommendation is every 3 to 5 years.

AC Efficiency: Battling Heat

The ductwork is the first place where the cool air can encounter heat and lose its effectiveness.

The insulation in a home is designed to SLOW the transfer of heat—from outside to inside in the summer and inside to outside in the winter. On a cool day, stick your head into the attic and check the depth of insulation. It should be at least 12 inches deep.
Openings around doors and windows can also develop gaps, allowing air to be forced out with each cooling cycle. Caulking will fill the gaps and prevent air from flowing out the window.
Close window treatments during the heat of the day on the south and west sides of the house. Solar gain can increase indoor temperatures by as much as 10 degrees.
Don’t add to the problem if you can help it. Use heat-producing appliances less and later in the day when outdoor temperatures have dropped.

AC Repair 77845

Guide to Reduce Summertime AC Repair 77845 Costs

The summertime heat does not wait for the official arrival of summer; it is here in full force. For the next several months, Hill Country Texans will seek relief inside, in air conditioning. Fortunately, there are steps to take to assist the air conditioner to cool the home and reduce the risk of costly AC repair 77845.

Keep the Cool Inside

Sealing, caulking, and adding insulation is a good idea at any time of the year. However, be careful when adding insulation when the attic is extremely hot.
Exhaust fans in bathrooms and kitchens have their use but use them sparingly. While you push moisture and smell outdoors, you pull hot air inside to replace it.
Attic fans can be used comfortably in the spring but consider covering an attic fan during the summertime with an insulative barrier.

Keep the Heat Outside

The heat from the sun, called infrared energy, can be blocked by heavy drapes or blinds. Letting the “sunshine in” can raise the inside temperature by 10 degrees or more, so close the window dressings during the heat of the day. This reduces the call for cooling and avoids stress during peak air conditioning hours. Increasing unnecessary stress on your air conditioner can reduce the need for costly AC repair 77845.
Schedule the use of heat-producing appliances with peak temperatures in mind. Use countertop appliances rather than an oven or stovetop. Better yet, grill outside. Schedule dishwashing and laundry during the early morning or late at night, the coolest part of the day.

Keep Air Moving

There are two advantages of moving the air with ceiling fans.

Moving air feels cooler than static air. It causes the moisture on the skin to evaporate more readily.
Hot air rises and will stay in place until acted upon. A ceiling fan circulates this air and cools the entire room from top to bottom.

Keep the Temperature Steady

It is tempting to walk into a room that feels hot and turn the thermostat down a few degrees. But this does not produce the desired results.

Cooling a space requires cooling the surfaces and furnishings within the room along with the air. This takes 30 minutes or longer, while the desire is immediate relief.
“Bumping the thermostat” up and down creates stress on the air conditioning and is energy inefficient.

It is best to . . .

Keep to a Schedule

Newer thermostats are programmable, and some are accompanied by cellphone apps for better efficiency and convenience. Learn to schedule temperature changes for comfort and energy savings. Find a temperature that meets the comfort threshold for the entire family and don’t alter it until the …

The family is sleeping—turn the setting up about 5 degrees for energy-efficiency
The home is vacant while everyone is at work or away—turn the setting up about 5 degrees for energy efficiency

A Smart thermostat will accommodate changing the temperature setting on the fly if the schedule changes.

Keep Your AC System Maintained

It is very important to change the air filter often—at least every three months.
It is equally important to schedule a maintenance visit by a Mullinix-trained AC Repair technician at least annually. We strongly recommend a Spring and Fall AC maintenance visit to ensure your system is properly functioning before the two busiest times of the year for your AC system. A well-maintained system will reduce AC repair 77845 costs.

These maintenance tasks can avoid expensive AC repair 77845 and inconvenient breakdowns and keep the air conditioner running smoothly.

Keep Upgrading Your AC System

Air conditioners have a limited useful life—the average air conditioner lasts between 15 and 20 years. When the time comes for replacement, invest in upgraded efficiency whenever possible. Seasonal Energy Efficiency Rating is the scale used for air conditioners. The higher the SEER number, the greater the efficiency.

Let the Mullinix AC Repair Team Reduce Your AC Repair Costs

Reducing air conditioning operating and AC repair 77845 costs during the summer months doesn’t have to be a monumental task. Using smart habits, a few minor home improvements, and regularly scheduled HVAC maintenance will keep your home comfortable without costing an arm and a leg. Keep cool during the summer and keep your energy costs under control with these helpful tips.

AC Installation 77845

Your Pre AC Installation Checklist

What To Expect BEFORE Your New AC Installation

So you are thinking about investing in a new HVAC system. We want to make sure you are prepared for the installation process and that you have your due diligence completed before installation day.

We have created a Pre AC installation 77845 checklist so you ask the right questions before your new installation, understand your warranty, and what happens during the installation.

Pre-Install Checklist

Prior to the new AC installation, our technicians will review with you the size of the HVAC system required for your home based on its size, number, and size of windows and doors, amount of insulation, ductwork design, and your family’s lifestyle. This research will be used to determine the right size of HVAC system that your home requires.

Once a unit(s) size is determined, our AC installation 77845 experts will review the manufacturer’s performance data to set expectations on any increases in utility costs that may or may not be anticipated, discuss air quality improvements expected, and any additional features and benefits of your new HVAC system.

Lastly, prior to the new AC system installation, we will review the system warranty. We want to make sure that you fully understand the terms and conditions of your HVAC warranty. Common HVAC warranty options are parts and labor, compressor, and full system.

What Questions You Should Ask When Selecting Your New AC Installation

Finding the right size unit for your home is the most important step in selecting a new HVAC system. Here are some terms that will be used to better understand this process.

What Does Ton Of Air Conditioning Mean?

BTU to tonnage ratio is 12,000 BTUs to 1 ton. AC tonnage refers to the amount of heat your HVAC unit can remove per hour. On average, 1 square foot of space equals 20 BTUs. The size of your new HVAC unit will be calculated based on your home’s square footage.

HVAC Venting Explained

Your HVAC system is vented outside of your home, usually through the roof in some fashion. This venting system will remove combustible gases from your home. If this gas is not removed, it can be very hazardous to your health and it will reduce the HVAC system’s efficiency.

What Does AC Refrigerant Charge Mean?

Your AC system uses a refrigerant as a coolant. The refrigerant charge is the amount of refrigerant in a system. Too much or too little refrigerant can cause problems with the HVAC system.

AC Installation Checklist: Day of the Install

Once the RM Mullinix AC team has determined the size of the system to install, it is time to get to work with your new AC installation. Our team of AC installation 77845 technicians will remove any existing HVAC system components and install your new system. They will perform a series of tests and calibration to ensure proper installation and function. We will walk you through the user guide to ensure that you know how to use the new system.

How to Determine if You Need to Upgrade Your Current HVAC System or Need AC Repair

Your HVAC system is one of the most expensive “appliances” in your home. Determining when it is time for an AC repair appointment or time for an AC replacement is a significant decision that should not be taken lightly.

If you are currently evaluating your repair or replacement options for your HVAC system, we have put together some pointers that will assist you in your decision.

Telltale Signs Your AC You Need an AC Repair Appointment

Is your HVAC system a senior citizen?

The average life expectancy of most HVAC systems is around 10-15 years. Properly maintained systems with needed AC repairs made as needed will increase the lifespan of your system. Missing routine maintenance and prolonging needed AC repairs can cut the system lifespan quite dramatically. Aging HVAC systems will be less efficient and can require more frequent maintenance and repairs.

Frequent AC Repair

Systems that have had routine maintenance neglected often times require more frequent repair. The cost of these repairs can sometimes begin to approach the cost of a new AC system. In addition, a failing HVAC system is not as energy efficient and can cost more in utility bills.

An AC replacement can be a money-saving investment if your repairs are beginning to equate to the amount you have spent on repairs and loss of energy efficiency.

Loss of Efficiency

New HVAC systems are designed to be more energy efficient than their predecessors. Reducing utility bills is great for budget-minded homeowners. In addition to reducing energy consumption, newer HVAC systems greatly improve indoor air quality. Another perk to consider: opting for a newer system can even increase the value of your home.

Best AC Temperature to Avoid Costly AC Repair

Best AC Temperature to Avoid Costly AC Repair

We often get the question from our customers, “What is the best temperature for my AC?” This question has many variables to have just one answer.

It is humid in Texas, and the humidity plays a vital role in determining what you set your AC temperature.

Soaring summertime temperatures bring with it a higher level of humidity in the air. Between the warm outdoor air and the humidity, Texans will use their air conditioning system nearly all year long.

What temperature should I set my AC to avoid HVAC repair?

The U.S. Department of Energy suggests adjusting your thermostat higher during the time when you are sleeping or you are not at home. ERCOT (Electric Reliability Council of Texas) recommends that 78 degrees is the standard HVAC setting to remain energy efficient and for your HVAC system to operate at its best and avoid costly HVAC repair.

Your AC thermostat is independent of all of these factors and is based on personal preference. Adjusting your thermostat results in higher utility bills, a harder working system in the summer heat, and wear and tear on the mechanical components of your HVAC system.

How do I adjust my thermostat for the best humidity control?

High humidity makes it more difficult for your perspiration to evaporate. This results in you feeling warmer when humidity levels are higher. Combatting humidity is only half the battle. Fighting off mold and mildew within your HVAC system is a concern when fighting the humidity battle. Excessive build-up of either can result in diminished HVAC efficiency which can lead to costly HVAC repair.

What thermostat setting is best for your pets?

Thermostat settings should take into consideration the comfort level of your pets. Temperature settings can vary widely depending on the type of pet, their species, and their overall health.

Dogs’ comfort is similar to that of their human owners. You do need to be careful to not adjust the thermostat too high when you are away to avoid overheating.

Cats can tolerate heat much better than dogs. You will often find cats relaxing in the heat of the sun, even during the warmest summer days. They do require plenty of fresh water to keep cool.

Most pet birds originate from the tropics and are used to higher temperatures. Rabbits also can tolerate slightly higher temperatures, but they should be kept in an environment below 80 degrees.

What thermostat setting is best for your computer and electronic equipment?

Keeping your electronics operating at their highest level requires them to be kept cool. We strongly encourage you to read any documentation provided by the manufacturer regarding storage temperatures.

The American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE), changed their recommendations for IT equipment in 2016. Previously, the organization recommended a top temperature of 77 degrees Fahrenheit. Currently, that recommendation is a high of 81 degrees F, so your computer and other electronics should be just fine if you set your AC to 78 to 80 degrees.¹

Remove Thermostat Confusion

Constantly changing your AC thermostat can be difficult to manage. Extreme changes can prompt unnecessary AC repair. Call a Mullinix AC repair technician to discuss thermostat settings, installation of a smart thermostat, and additional AC thermostat related questions.

HVAC Maintenance Checklist For Homeowners

Spring HVAC Maintenance Checklist

The moderate temperatures this winter make Spring feel more like summer in Texas. With warmer-than-average temperatures, Spring HVAC maintenance has never been more important. Here is your spring HVAC Maintenance checklist to prepare your home for the upcoming summer heat.

Change Your HVAC Filter

The minimum your air filters should be changed is every 30-60 days. Households with pets and family members with compromised immune systems should replace their filters more often. A fresh, clean HVAC filter allows the conditioned air to flow freely and improves indoor air quality.

Cleaning Ceiling Fan Blades

Ceiling fans collect a great deal of dust. Removing dust built up in the spring will provide better air quality and allow your fan to be more efficient. Wiping dust buildup and reversing the blade direction for the summer is a great springtime HVAC maintenance step.

Clean Your AC Vents

We recommend removing the vent cover and cleaning it. Although it is not a substitute for professional HVAC duct cleaning, it is a great way to improve air quality and identify any potential deeper issues.

Check Your Thermostat

Your HVAC thermostat needs to have the batteries replaced every six months. We recommend changing your thermostat batteries at the same time you change your smoke detector batteries. If you are using a smart thermostat, change your settings to the summertime operation.

Clean Your Outdoor Condenser

Remove any leaves, branches, or other landscaping debris from in and around your outdoor AC unit components. This is also a great time to remove any overhanging branches or shrubs from the area around the unit.

HVAC Maintenance That Your HVAC Technician Should Complete

Cleaning your evaporator coils should be left to the professionals. The evaporator coils are located inside your AC unit, normally above the blower motor. Cleaning your coils will improve the efficiency of your HVAC system and provide better indoor air quality. This requires compressed air and a commercial coil cleaner, so that is why we strongly recommend calling Mullinix AC maintenance to assist with this task.

Clean Drain Line and Drain Pan

Moisture buildup can produce mold and algae. This can be collected in your drain line and the drain pan. This debris can cause clogged lines and the drain pan to overflow. The result can be very costly and easily avoidable. Cleaning the drain line requires compressed air and is best left to the professionals.

Cleaning the Outdoor Condensing Unit

Dirt and debris can drastically affect the efficiency of your HVAC system. Our HVAC maintenance technicians can properly clean the outdoor condensing unit, check for bent or damaged blades, and identify any potential future breakdowns of your HVAC system.
