Testimonials
We purchased a HVAC unit and had spray foam insulation applied a year ago and are very pleased. The crew was very professional and answered all our questions. This weekend the unit went off due to a sensor. It was not the air conditioner but a plumbing issue. Lionel came out within 30 minutes and new exactly what it was..He showed me what to do to keep it from happening again. I would highly recommend his company. Thanks again Lionel.
Friendly and knowledgeable staff, highly recommend.
Had a new unit installed in October and couldn’t be happier. Came when they said they would. Quoted very reasonable price. Installed the next day. Great company and highly recommend!!! Had an issue and got a call back immediately after hours. Came out early morning next day, diagnosed and fixed. Clogged drain! Again, highly recommend!!!!
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.
They are the BEST and the service is fast and they are so friendly. I recommend them with 10 thumbs up!!!
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
LOVE them!!! Great service, QUICK service – Always feel like a priority!
Serna has installed 2 A/C systems for us over the last 8 years. We are completely satisfied with their work. They are extremely knowledgeable, creative in solving problems and cost competitive.
I cannot say enough good things about this company. Super sweet repair guy. It was wonderful that he took my “after hours” phone call. He worked quickly and got my air conditioner up and running in no time.
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.
