"Super friendly and did a great job!"

"Comfort by Design did a fantastic job with my water heater from start to finish. When I called, the receptionist was highly knowledgeable about scheduling and pricing, and she was quite willing to let me call other places since I was researching price and availability. I ended up sticking with Comfort by Design largely because the receptionist was not pushy, listened well to me, and had technicians available that day. I like hiring companies with whose employees listen to me and work with me to solve a problem, as opposed to pressuring me to choose them or to buy more than I'm comfortable with. My initial interaction with Comfort by Design met those criteria. A technician arrived within the time-frame I was quoted, and he had the part I thought was broken on my water heater. After diagnosing the issue, though, he discovered that there was at least one other broken/malfunctioning part that needed to be replaced. He showed me the problem and explained the process of replacing it. After discussing my options with the technician, I decided to replace the water heater. At no point did I feel pressured into making that decision. The best surprise of the day was that Comfort by Design was able to replace the water heater immediately. Another technician was available to immediately bring the water heater, and the two techs worked together to install the new one and remove the old one. They also carted the old one away. Before leaving, they patiently answered several other questions I had, and they explained and scheduled the necessary inspection of their installation. They did a great job respecting my property while moving the large water heaters, and they did a great job cleaning up after themselves. Finally, the cost was reasonable and about what I expected to pay. Custom by Design is definitely going to be the first place I call should I have any plumbing or HVAC (they also do HVAC!) needs in the future."

"Greg and Sean acted very fast, due to our situation. Our furnace died, and we needed it to be taken out, and then install a new dual stage Bryant furnace. They put me in front of a few jobs. I truly appreciated the fantastic value I received, them both being up front with me, and the unique ability to be on time coming up the mountain way. I will always recommend them, as well as use them if need be, in the future. Tremendous deal!!!"

"every one was on time and made shure we understood price and how to take care of our new furnace, and sofar it works great. and we have recommended sears to all our friends and family, thank you so much for getting the work done so fast."

"Mr. Ferrell worked with my husband over the phone to fix the problem. It was surprisingly fast and stress-free. To have the work done remotely in less than an hour was wonderful."
