    What Our Customers Say

    This will save you money!
    This was well worth the money. Quick and easy to work with. The heat and air guys wanted me to buy 7 tons and after it was all said and done I only need 3.5tons. Was a great service to capitalize all of my energy efficient components of my new house.”

    Michelle and Billy Fields – Carney, Oklahoma

    My wife and I employed David Brown to design HVAC for our dream retirement home. David gave us a great usable working plan, one that we could do some of the work ourselves. David helped us with sizing requirements and with some space difficulties. David told us he would not be finished with the plan until we were happy with the plan. We couldn't be happier with the working plan that David provided for us. After living for years in a house where the plumber designed the system and all the faults that came with that we are looking forward to the comfort provided by ConsultAir in our custom designed plan. David's fee has been the best money we've spent on our house so far. You just can't go wrong with ConsultAir and David Brown.”

    Rod Williamson – Grand Saline, TX

    I recently contracted with ConsultAir to perform a Manual J, S, and D for a custom home i am building (General Contractor). The experience was very positive. I had previously performed a Manual J analysis on an install i did about a year ago, so i have some experience on what to look for. David Brown was very thorough about collecting all the data needed to get the most accurate heat loss, heat gain, equipment and duct sizing. He was particularly good at explaining the various options for fresh air recovery as well as the benefits of single stage, two stage, and modulating equipment.

    His expertise helped catch a few errors that would have been made by the HVAC contractor. Great experience!”

Welcome to Our Website!

My name is David and my experience in the heating and air conditioning field dates back almost 30 years. Over that time, I’ve worn a lot of hats but residential HVAC design has always been a passion of mine. So back in 2011, I decided to start ConsultAir, a residential HVAC design and consulting company.

Since then I’ve partnered with hundreds of homeowners, homebuilders, and HVAC contractors across the country... and have been loving every second of it!

Please take a look around and feel free to reach out to us with any questions you may have. We are always happy to talk.
