Testimonials

Always prompt and professional every time in three to four years! Cannot ask for more than that!

They did the spray foam in my pet resort and the temperature stays 4 degrees cooler than what I have the thermostats set on. That’s a huge deal in triple digit Texas weather! They were also somewhat less expensive than others. I’d not even attempt to use anyone else.

Y’all I made it home from vacation last night to a 90 degree house. I called around this morning & was initially told Friday would be the earliest someone could come out. Thanks to Serna Services for coming out & getting us up until parts come in.

Serna services came out for our spring service check up. Very thorough and answered any questions I had. Thank you Serna Services.

I knew I found a good one when he was reading the vent temps correctly, not using infrared surface readings but putting probes in the ducts properly. Also advised on specifics of overflow drain code, demonstrated knowledge and expertise. Immediately found a small leak that he corrected which went unnoticed by other AC people. Price was very fair. We would be fortunate to have more people like this. Highly recommend.

It’s a pleasure working with Serna. They come when they say they’ll come, do what they say they’ll do, prices are competitive and they even finished early. The work has been flawless on both the A/C side and spray foam side. The crew answered all questions and cleaned up after themselves. Couldn’t be more pleased

Serna does a great job for us! They installed HVAC in our new construction and help us maintain existing units in other buildings. They also did a phenomenal job spraying closed foam insulation in our shop. I highly recommend you ask for Jesse to be your tech. He’s a straight shooter.

My wife and I have used this company for over 10 years now. They just completed an entire new system inside and out. The original date was approximately two weeks, I was floored when Gloria called and said they would be at my house in two days. Michael was the original one who came and inspected my old system. He was very professional and explained everything to me. The two guys that installed everything did an excellent job, very professional, respectful and like Michael explained and did everything they said they were gonna do. Great company, I highly recommend. Gloria was also awesome at helping me set up the financing.

I was very , very happy with Lionel and his services today. He was very kind and explained everything to me as he had to do repairs. I was so thankful he did not just rush through the job and do whatever he thought he needed to do on his own, he did show me what was wrong and what needed replace?And if I was wanting to do so , he would do it , and I was very impressed. So I well, definitely.\nTell others , family and friends and all I meet about this company’s services. I\nJust wanna say thank you again.\nFor a good experience Serna. I have to say , I called and you answered return my call right away and was very prompt to get someone out here to help me get my air back on and I give you my appreciation and good , thanks for that.
