Cody and Rob did a great job installing a replacement air handler and heat pump at my residence. They were very knowledgeable and professional, and were respectful of my property, cleaning up everything before leaving. Cody even came up with an easy solution to a problem with my condensate discharge line that I had been having for years. The system is working well and I am very pleased with it.

So today I had the pleasure of dealing with Jen while trying to resolve a issue with transferring the warranty for my parents. She was so very helpful and went above and beyond even calling the trance company for me. We have used try county for our hvac for over 10 years and have always found them to be proffessional and helpful but Jen stood out today!

Got my 2 hvac units replaced last April and went through two maintenance services already. Excellent service and advice in choosing the new hvac system they installed. Very knowledgeable techs and not afraid of questions. Trustworthy people & company. A little bit on the high end of pricing but exceptional value for the money. Very happy working with Tri-County Aire!

Tim and Chris were fantastic. They were professional and prompt. Being a previous service technician I verified that their work was very detailed and complete. I was checking out their progress during the day as they worked and they did not mind at all. Our existing unit was a Trane unit that was 36 years old and still working but was just rusting out. We are happy to have another Trane to replace what we had. We received multiple quotes and the price was fair and I would highly recommend Tri-County AIRE to anybody in this area.

Tri County installed a new heat pump for us this week. Tim and Chris, the installers were excellent. They rolled plastic sheeting across all workspace flooring and cleaned up afterward. The install was perfect. I recommend Tri County - they're true professionals.
