Air Conditioning and Heating
Service
We service all makes and brands. Our factory trained technicians have the tools to repair your system right the first time.

Lennox Dealer
We have been a Lennox dealer since 1968. We believe in Lennox products because of their commitment to research and development, their warranties, and the relationship we have built over 40 plus years. We have customers whose multi-speed Lennox heat pumps are still in operation after more than 30 years of quiet dependable service. We specialize in high efficiency heat pumps.

Zoning Systems
Zoning Systems can take care of those houses that seem to be hot on one side and cold on the other. The Lennox iHarmony zoning system paired with the new XP25 is the most efficient zoned communicating system available.

Licenses and Certifications
We are licensed and insured to work in Texas, Oklahoma and Arkansas.  We have the experience and training to fix your problem correctly the first time.

Commercial Chilled Water Systems
We have installed thousands of tons of hydronic systems. We sell Carrier and other brands of chillers. Call us today to see how we can help you with your commercial or industrial cooling and heating needs.

Mini-splits
We also service and install Daikin mini-split heating and cooling systems. These quiet and efficient mini-split systems work perfectly in situations where a traditional ducted system cannot be installed easily. We have chosen to partner with Daikin because of their reputation for quality and efficiency. Daikin is the largest air conditioning manufacturer in the world.

Load Calculations
We use Wrightsoft software for our load calculations. We are available to perform a load calculation on your project. We measure each of our jobs ourselves to ensure accuracy in the final project. Whether it is manual J, manual N, or manual D, we can perform the calculations to ensure your new system is the most comfortable and efficient that your home or business has ever seen.
Indoor Air Quality
Today our customers are focused on indoor air quality (IAQ) more than ever. We now have new improved filtering technology that can bring a breath of fresh air to your home. Talk to us about an IAQ upgrade today!

UV germicidal lights are an important part of any IAQ strategy. That is why we include them on every new high efficiency system we install. These lights bath the evaporator coil of your unit in a bright light that kills mold, viruses and bacteria.

Whole House Dehumidification is one of the most important aspects of IAQ. As you can see in the chart below, when indoor humidity is between 30-50%, many pests and aliments can be eliminated or brought to a manageable level.
SunSource Solar
  • Every high efficiency Lennox system we have installed since 2010 is “SunSource Ready” This means that our customers have the option of powering up to 100% of their HVAC and home electrical needs from the renewable power of the sun! It also means our customers are eligible for an extra tax credit of 30% of the purchase price of the system. Call today for a free site survey and estimate. Hurry, the tax breaks expire next year!
