Quality Mechanical Corporation describes itself on its website as a family owned mechanical contractor in the New Haven County of Connecticut that installs, repairs and services heating, air conditioning, ventilation and plumbing systems. The site says it has been in business for 79 years. A 2023 customer said they called in the morning because the AC was not working, and someone was sent out within an hour. That 2023 customer said it was fixed in no time. A 2022 customer with a 7-year service contract said a technician came by 1:00 after their morning call about a furnace that stopped working, identified the problem, and that rush orders were going in for the part. A 2021 customer said the job was on time and that everything was checked thoroughly before leaving. A 2025 customer said a first technician diagnosed a water heater's pilot light problem as a dirty assembly and cleaned it for $381, but the problem returned within weeks. That 2025 customer said a second technician found the thermopile had not been properly cleaned and redid the job, and that a $240 diagnostic fee was later billed even though the visit had been described as free. That 2025 customer said they paid the invoice under protest after promised call backs never came and emails went unanswered. A 2021 customer said they texted pictures and an address to Matt as he requested, and still had no response over a month later. Connecticut lists an active S1 heating and cooling licence, HTG.0402323-S1, held by Quality Mechanical Corporation.
I’ve had an extremely disappointing experience with this company. Earlier this year, our water heater’s pilot light repeatedly went out. On 3/18, the first technician diagnosed the issue as a dirty assembly, cleaned it, and left. We paid $381 for that visit. However, the problem returned within weeks. When I called again, I was told that a follow-up visit would be scheduled at no additional charge, since the issue had not been resolved. On 5/7, a second technician confirmed that the thermopile had not been properly cleaned during the first visit and redid the job. Despite being assured this visit would be free of charge, I was later billed $240 as a diagnostic fee. Since then, I have made multiple phone calls and sent emails to resolve the issue. Each time, I was promised a call back from the responsible person, but no one ever followed up — and my emails have gone unanswered. Instead, I keep receiving automated “past due” notices. I ultimately paid the invoice under protest, simply to stop the harassment. I find this behavior dishonest and deeply unprofessional. It’s a matter of principle — no customer should be misled or ignored like this. I will not be using this company again and strongly recommend that others look elsewhere for reliable service and fair treatment.
Called this morning because my AC wasn’t working. They called me right back and sent someone out within an hour. Fixed in no time. I couldn’t ask for better service. Chris was excellent. Highly recommend this company.
We’ve had a service contract with quality for 7 years and have never had a single negative experience. Last night our furnace stopped working so we called this morning and a technician came by 1:00. Identified the problem and they are putting in rush orders for the part we need first thing Friday morning even though the office is closed til Monday. Not to mention, the technicians could not be nicer or more friendly. I rarely write reviews but they’ve been so great, I had to give them credit. Highly recommend!!
Extremely unprofessional! I called this company on 10/25/21 and I spoke to Matt. I explained my concerns, and he let me know that my concerns were fixable. He asked me to send pictures with my address. Immediately after hanging up with Matt I texted my address and the pictures he requested. It’s now 11/29/21, over a month later and still no response. I understand he could have been busy at the time I called, but he could have gotten back to me at some point during that week. I don’t recommend this company to anyone.
On time professional and personable. The job looks Great!! They took pride in the work they did which is hard to find at times. Checked everything out very thoroughly before leaving !!!
