Still no resolution. After day 28, they decided they did not want to do any more resolution work with us and that we could continue using their equipment until we found a new HVAC contractor to install yet another compressor, air handler, and coil. They finally took their equipment out for the final time, 6 weeks later.

In June of 2025, the air conditioner stopped working. I thought I would try to keep with the same company for simplicity. The person who came to the house to look at it was nice but told me it had to be replaced. He said he would let them know at the office and someone would call me to discuss the possibilities of replacing the unit. no one called. I finally called the office and John stated he would call me later that evening or for sure the next morning with an estimate. no one called. after waiting another 2 weeks to hear from all hours, I decided to have another company install a new unit. They were, however, very prompt in sending a service bill for $140.00. since they were not in a hurry to call me back I was not in a hurry to pay the bill. two months later they are now today wondering why I haven't sent the money. i would have sent it immediately if I hadn't been kept waiting on the return call with an estimate as promised. I tried to return their call after I got off work to explain why I hadn't yet sent payment and that I was waiting to see how long it would take to get a return call from them. Even though I called before 5pm which is the time they are supposed to be open till, no one answered. I tried twice. No answer. I am sending their payment but am hoping they read this review for improved customer service. Follow through is an extremely important part of customer service and this was lacking in my experience.

I appreciated their service and trusted them already. Recently the furnace quit in the middle of Friday night. Saturday morning the emergency line returned my call promptly and hurried over to help. They did estimate and collect a fair after-hour fee based on time. I was again not disappointed when I received the final bill. They are trustworthy and not out to gouge you.

I called this company to perform an inspection of my furnace. They came out all seemed fine and…read morethey said I may need a new motor soon but it was running fine for now. About a week later due to extremely cold temperatures the furnace began to struggle so I called to have the part replaced. They replaced the condenser motor. Our furnace began to smell of burning plastic we called...a tech came out and said it was probably just the new part that was causing the smell. Two days after the part was replaced our furnace died in the middle of the night.They sent someone out and it was determined that the blower motor needed to be replaced.... This was done the next day. I believe they replaced the wrong part in the first place but they would not admit that. They were however gracious enough to take 10 whole dollars off my bill. Not impressed.
