Our AC went out over the 4th of July weekend. I called Precision Air and they showed up within an hour and fixed the problem within 30 minutes. The tech knew exactly what to do and how to get me and my family back into a cool home. Will definitely use this company again.

Zeke came on time, checked the system, and knew exactly what was the problem right away. He also fixed it quickly, and allowed us to have cooling working again over the hot weekend. He knows his stuff. Amazing guy and service. We highly recommend him!

Can you install AC in a house that doesn't have it?


If you have existing ductwork (your furnace blows air through vents) we can usually attach the air conditioning components to share the ductwork.

If you have no ductwork, we either install new ductwork or install a ductless mini-split AC system that attaches to your wall and uses a remote control.

We’ll take a look, provide you with a free estimate and help you decide.

How much does a new air conditioning unit cost?


Similar to buying a new car, there are less expensive units, and more full-featured options. We will study your unique space and give you advice.

  • How many square feet can it cool?
  • How energy efficient is it?
  • How much of your existing system can be reused (ductwork, electrical, humidifier, etc)?
  • Will there be upgrades (UV disinfection, filtration, humidification, thermostat, code requirement work)?
  • How much can you save with tax credits and rebates?

Do you offer financing?


We offer financing options with low monthly rates. A large percentage of our clients choose to take advantage of $0 down financing. We can guide you through the process.

Should I replace or repair my central air conditioning?

This depends on 2 factors:

Is my air conditioner the right size for the job? It is common for builders and homeowners to choose based primarily on price, but an undersized HVAC works extra hard to keep your home cool. This shortens its life and drives up your electrical bill.

Was it maintained according to the manufacturer’s recommendations (i.e. regular tune-up and filter changes) or was it only inspected when it broke?

If you answered yes to both of these questions, your central HVAC system should last 12-15 years.

Another consideration; older HVAC units use FREON (technically called HCFC-22) as the refrigerant. It circulates through the “veins” of your air conditioner’s compressor to make them cold.

Under the U.S. Clean Air Act on substances depleting the ozone layer, the U.S. phased out Freon in the 1990s and, in January 2020, stopped production and imports of air conditioners that use them. Why? Because the chemicals are bad actors. They enter the stratospheric ozone layer and destroy it. The ozone layer helps protect us from harmful ultraviolet (UV) radiation that can cause skin cancer and cataracts.

So what does this mean for people with air conditioners that use Freon?

According to the EPA’s website, “the most important thing that you can do is maintain it properly because appropriate servicing minimizes potential environmental damage and prolongs the life of the system.” “Homeowners should also request that service technicians locate and repair leaks instead of “topping off” leaking systems to protect the environment, minimize future service calls and repair costs, and reduce equipment operation costs by improving performance. It is also illegal to intentionally release any refrigerant when maintaining, servicing, repairing, or disposing of AC equipment.”

Summarizing: If you have an older system, get an AC tune-up every 6 months. If the refrigerant level is low, find the leak and fix it, or discuss replacing the system with a new, clean, energy-efficient model.

In 2020-21, while we were all stuck at home, many Texans decided to renovate or add another room to their home. Know that every air conditioner is designed to efficiently cool a predefined space rated in square footage. When you add to that square footage, you may find that your current AC struggles to keep up. In this case, consider an AC replacement or adding a ductless wall unit.

Is there a best time to install a new air conditioner?

Many manufacturers offer off-season rebates, but we are here to take care of you at any time.  Just because you click the thermostat and nothing happens, or the HVAC is running and the air is not warm or cool,  doesn’t justify a brand new unit. Invite us to have a look.

If you do need a new furnace or air conditioning system, we can usually have it installed in hours.
