Heating, Ventilation,
Air Conditioning 

Our HVAC services revolve around the lifecycle of an air conditioning system. We design, install, maintain, and repair air conditioning systems for residential and commercial customers. 

New Air Conditioning System Lifecycle

Most of our customers already have an air conditioning system designed and installed in their house, so that lifecycle may be something like repair, maintain, and then replace. Regardless of whether you already have an air conditioning system or are building a new house, we are here to help!

Existing Air Conditioning System Lifecycle

If you’ve lived in the Houston area for any length of time, then you’ve likely experienced the dreaded AC outage. You first start wondering why you’re sweating inside your home, then you notice that the thermostat is showing a higher temperature than it is set at, and then it hits you – the AC is not working! That’s when you give us a call or text us at 281-346-9798 and we will get there as soon as possible.

At Uni-Serve Air Conditioning, we have seen it all. From systems not cooling because the thermostat is set to Heat to compressors burning up to electrical components going out. No matter what it is, we will do our best to fix your air conditioning system. Not to brag too much, but we have some of the best air conditioning and heating technicians there are. So if we cannot fix it, then it’s likely at the point where it cannot be repaired. At that point, we will work with you to find the best option to replace your HVAC system or a portion of the system.


Uni-Serve Air Conditioning offers maintenance plans to shield against HVAC system outages. We call our preventative maintenance plans the Uni-Shield Maintenance Plan. This is a service agreement that comes with multiple benefits. To begin, we come out twice a year (spring and fall) to check and clean your system. You also obtain preferred customer status which means you do not pay any diagnostic fees or after hour fees, and you get a 15% discount on repairs.

By having Uni-Serve Air Conditioning come out twice a year, we are able to detect some failures before they happen. For example, one of the most common repair tasks is replacing a capacitor. Capacitors have a rating measured in Micro Farads. Over time, a capacitor will weaken and will eventually get to the point where it can no longer start your compressor or condenser fan. This means your air conditioning system will NOT operate. During routine spring checks, the capacitor rating is one thing we measure. If the measurement is below the listed rating, we will suggest replacing it so that your air conditioning system does not go out during the heat of the summer. There are many other things we check and clean so that your system will operate at its designed capacity and efficiency.

Many people just want their AC to work. They don’t want to think about it. However, we strongly recommend routine maintenance on your HVAC system so that it operates at its designed capacity and efficiency. When it’s not, then the lifespan of the HVAC system is decreased. So let Uni-Serve give your HVAC system some TLC so we can keep it running as long as we can!

Furthermore, Uni-Serve offers additional shields! This includes providing and changing out your filters, cleaning your dryer duct exhaust, and cleaning your bathroom exhaust fans. These are all very important tasks that often get overlooked. Not changing your filters often enough will decrease your air conditioning system’s efficiency and will decrease its lifespan. A clogged dryer duct exhaust is a fire hazard.


Uni-Serve Air Conditioning specializes in the installation or replacement of HVAC systems. We have strict standards and procedures for every aspect of installation. From how we move equipment in and out of your house to how we attach ductwork to how we start up the system, there is no detail too small! We know that purchasing a new air conditioning system is a large expense, so we want to make sure it is installed in a way that helps it operate at its peak performance for many years.

The process of installing a new air conditioning system or replacing an existing air conditioning system begins with you. We will meet with you to determine what type of HVAC system you want. This can be a meeting at your home or you texting us your preferences. We want to make sure you feel comfortable with the entire process. Do you want to spend as little money as possible? Do you want the most energy efficient HVAC system? Or do you want a happy medium? Regardless of what you want your next air conditioning system to be, we are here to help you. There are not any heavy sales pitches to get you to spend as much money as possible. Our goal is to provide you with an air conditioning system that meets your needs and works with your budget.

Since air conditioning systems are large purchases, we offer financing to help spread the cost out over several years. We offer several plans so that you can find the option that works best for you. You can apply for financing here.



If you are building a new house, adding on to your house, or doing any type of renovation, we can help you design a new HVAC system. The owner of Uni-Serve Air Conditioning is a Licensed Professional Engineer in the State of Texas. He spent many years designing HVAC systems for schools, office buildings, restaurants, and custom homes in the Greater Houston area.

The process of designing an HVAC system starts with heating and cooling load calculations. That is the process of analyzing how much air conditioning and heating is needed. This is based on the location, size, orientation, and usage of the space that is going to be heated and/or cooled. It is extremely important that the HVAC system is sized properly. A system that is too large will short cycle. This means that the space will heat or cool really quickly and then the system will turn off. This process allows humidity to increase or build up in the space. A system that is too small will not be able to properly heat or cool the space.

The amount of cooling a system can provide is typically indicated in ‘tons’ of cooling. The amount of heating a system can provide is typically indicated in BTUs. BTU stands for British Thermal Units. A BTU is the amount of energy required to raise the temperature of one pound of water by one degree. A ton of cooling is equivalent to 12,000 BTUs/Hr. If you’re wondering, a ton of cooling refers to the rate of heat transfer that results in the melting of one ton (2000 pounds) of ice over a 24-hour period at 32 degrees Fahrenheit. One ton of ice absorbs 288,000 BTUs over a 24-hour period. Therefore, a ton of cooling is equal to 12,000 BTUs/Hr.
