  • Very responsive when my heat pump went down. Angie was great at scheduling the technicians and keeping me informed. Rey, the technician who helped me, was very knowledgeable, respectful, and wonderful to work with.

  • I have a Daikin ductless system; THe condensation drain had pluged so I called Thermall to fix the problem as well as preform an annual maintenance. Rey arrived, listened to my explaination of what was going on. In short order he preformed the annual and cleared the drain. He explained how the drain could get clouged and what I should do if it happens again. Rey and the other Tech's I have delt with are very professional, knowlegeable about the equipment they work on, and helpful.

  • This company was so great! I had a furnace fixed on a rental property. I paid for the service. It wasn’t until 4 months later they realized that it was still under warranty. The company refunded the cost of the repair. Thank you! Thank you! The kindness with which this company conducts business is not the norm. I will definitely be referring people your way.
