My office was about to participate in the pride parade, but my A/C unit was not working. Hektor made sure my unit was serviced the day before even though THA was booked. This is the second time I’ve called THA and both times they went out of the way to service my office.

Melissa, Liberty Tax Manager

Had a new water heater installed on 7/19/17. They did a great job! Tech Gilbert was very professional and thorough. Operations Mgr. Hektor Barcenas was great with follow up and addressed my concerns. Special thanks to Mike, supervisor in the Plumbing Division for his special assistance. I would highly recommend this company.

AC went out the day before Thanksgiving and they were the ONLY place willing to come out on Thanksgiving day to attempt to fix it. The ops manager himself came out and quickly diagnosed the problem. He was a complete professional through and through. Can’t say enough about this company!

Nathan Strang, Homeowner

Used these guys for 3 years and they are so good at what they do and very well priced. One of the hottest days in San Diego and of course the air goes out. They were so busy but THA made the time the same day and came out to fix our air. So thankful.

My A/C stopped working on Saturday around noon.  I called THA, talked to Matt, and by 3pm it was fixed. Well done!!
