As some others have said as well, my dealings with this business were extremely disappointing and somehow they had removed my last review. (Unethical at best)
My summary: new a/c system and it failed 5 years later. I called Harvey for a repair and he had a person come who offered to put in more coolant but said it may or may not fix it. Ironically this employee quit the company that day so the conversation continued with Harvey’s admin.. Harvey said the coolant fill should fix the problem and charged me $~1500.
The above repair did not work so I called back and asked the admin if we could come up with a game plan, including a quote for a new system. The admin (maybe his wife or daughter?) was extremely unprofessional and said “no, Harvey won’t call you. He’ll only come for a service visit again.” I stated that I was being reasonable, having bought the system from them 5 years ago and having already paid for an unsuccessful repair. I just wanted to figure out what we’d do next before I paid for another service visit. The admin called back and said Harvey “wasn’t interested in my business,” which was quite rich considering that Harvey was the one who didn’t stand behind his work—while also seeming quite inept with fixing air conditioning systems. I would not recommend wasting time or money with this company: sleazy and unethical

I am so thankful I have Tri County Heating and Air! They are they nicest, honest, accommodating, and reasonably priced local mom and pop company that goes above and beyond for me! Barb and Harvey Mathewes are just so amazing and have gotten me taken care of on the same day so many times! Harvey even came out on Christmas one year when it was freezing and my furnace broke and did not charge me anything extra for a holiday! Anyone looking for HVAC needs, they’re fantastic and local! Tri County Heating and Air coming through in a clutch! 🖤This is exactly how businesses should be run, tough to find in 2022! Can’t beat this company! Have used them for years and won’t go anywhere else! A business actually making a single moms life less chaotic in 2022, unheard of these days.
