Recommended Customer Reviews

I had my AC ducting completely replaced in the small crawl space under the house. The guys working on it (Jeff, Nate and can't remember the other technician's name) were great. I chose the hard ducting which was pricey and hard to install but the guys got it done. They were professional, diligent, and very courteous. I highly recommend them for Heating/AC work.

Vincent R. from Thompson Heating and Air Conditioning came out to our house after our bedroom flooded. He has professional, diligent, and did a fantastic job! Thanks, Vince!

Thompson Heating & Air-conditioning saved the day for us today! We called them when our air conditioning unit was acting up and Vincent came out the same day. He was so professional and knowledgeable which made us confident that we called the right company. Vincent was awesome and got our air conditioner pumper cold air again in no time. I would recommend THAC to everyone.

We called Thompson heating & air for a second opinion because we received an egregiously high repair quote from another company that just didn't sound right. Robert came out and was thorough, timely and explained everything. The price we paid for the service is quite reasonable. We truly feel we can trust his work which is priceless. Thank you!

We called these guys in Monday and they came out a couple days later. I was please that Robert called and said he was going to be here in 15 mins, which he was. I really like the customer service, and that I didn't feel like straight out of the gate it was gonna be a million dollars.
He was there for 15 mins, fixed the problem and we are happy customers with a working A.C.!!!
I will call them again.

Nothing but great things to say about this company! The technician Garrett was fast and efficient. He was able to fit us in right away, and was quick to solve the problem on why our ac unit had quit working. This is the second time we have used them for services and I won't hesitate to refer them to my friends and family! Thanks again Thompson heating and ac you have a happy customer for life!

Very pleased with the ease of the whole process from the estimate to getting the job completed. The installers were friendly and knowledgeable. The job was completed on time with no mess. I also recommended them to family who had a similar experience.

I used Thompson at my property on the Agua Hedionda Lagoon. Thompson attended promptly and after some confusion on what was required for fixing the furnace, they did the job quite successfully. The initial diagnosis was incorrect and it took the technician some time to figure out the problem (flu issue) and in the end the ownership at Thompson treated us very fairly and honestly. I would use their services again.

Thompson heating and air has been great to work with. They installed my air conditioner and it works great! They also worked with me to resolve a problem with my heater. They came out multiple times when the problem wasn't solved on the first try without charging me for the multiple problem solving sessions. They found the problem and suggested a reasonable course of action that didn't involve replacing the furnace like I think most places would have. Technicians are friendly as well as their staff.

Robert was great in checking that our AC and Heating was working great which it was. He was on time and performed the service quick but thoroughly.
