At 730 Joe and Anthony arrived. The new Bryant heater and Honeywell thermostat were installed flawlessly. We got the rundown on the new system and registered the product.

He noted on the invoice I was not happy with the system and stated he and the service manager would be back out the next week to check the system. As of 02/27/25 I have not been by contacted by anyone from this company. I have made multiple calls about this system and it is still not working correctly. To have this system put in was not cheap , and it is still costing money. I just want the system fixed so I can have proper heat in my home and an electric bill that is not almost $500.

I'm here in WA state and early this morning my mother in law calls and is just beside herself because there's a leak or something somewhere and water was coming into the basement.

I thanked him and proceeded to give the parents the number. As the morning progressed I gave my mom in-law Phil's number and he's currently taking great care of them.

What a crook of a company. I scheduled an appointment for 9:00 AM, yet the technician showed up at…read more8:20 AM. At that exact time, I was getting ready to call and cancel because I had already troubleshooted the issue myself and confirmed my system was working normally, so the service was no longer needed. When I originally called, the only fee mentioned was a $120 diagnostic fee. There was no mention whatsoever of a no-show fee or a travel fee. Now they are trying to force me to pay a $59 travel fee, even though the technician arrived before the scheduled appointment time. To make matters worse, this fee was not explained to me until after they had already shown up. Completely unprofessional and misleading business practices.

TL;DR: they refused service to long-time clients because we had the audacity to ask for a measly…read more$200 off their HVAC bid. Clients of theirs for years, no complaints. When we needed a new HVAC, we got an estimate from Frederick that was $1000+ over the estimate from another long-time, reputable local company. But out of loyalty to Frederick, we politely asked if they would shave $200 off to come *slightly* closer to this other quote. We actually hate haggling, but had read that you're expected to, for new HVAC. Can't hurt, right? They responded. Had they just said, "No, that's not possible due to XYZ," we would have hired them and paid the full price. But instead the rep explained why it wasn't possible, and then, in a polite but insulted tone, *rescinded their bid*, essentially telling us they would not be doing the job either way. All over a request for $200 off a $7000 job. We were stunned. Needless to say, we haven't called them for anything since, and we're the kind of easy-going, non-complaining customers contractors usually like to have. We got our HVAC at the other place and it's running fine, a few years later. Owner, if you're reading this: I get that you're doing well enough that you don't need to accept anyone's attempt to haggle, and can charge a lot more than the competition. Good for you. I'm purposefully not giving you a 1 star because I don't believe in trying to hurt someone's business. But talk to your guys about not reacting in a personal way to long-time customers. The reaction we got was really uncalled for. Maybe the guy was having a bad day, but you have to leave that behind when you're interacting with a customer, especially an established one. He could have just said "No, we can't do that, but let me know if you want to proceed with us." We would have.
