“The team was really helpful. Sadaf immediately helped me get on the schedule when my AC broke late on a Sunday night, and again at midnight during the week. Both times they got me back to normal in less than a day. David helped get my home taken care of for my family and was great with all my pets. He was pleasant, fixed my problems quickly, and explained everything as many times as I asked. He even gave me some advice to watch for in the coming years so I can plan for service in the future. This was a great experience!”

“David and the entire team were extremely professional. They arrived early, kept me updated on the progress, and stayed late to make sure everything was working. I highly recommend Comfort Defender and plan to share with all my neighbors and friends. Excellent customer service across the board from initial meeting to install.”

“David and his team did a great job, from start to finish, in replacing my old water heater with a heat pump hot water heater. The older heater was beyond its useful life and actually a risk to my household. David recognized that and that information. After establishing that I should remove the old water heater, I had several questions about what technology I should install to replace it. David was knowledgeable about unit efficiency, water volume, federal and utility rebates, and several other relevant topics. David provided me more than a few quotes on different types of water heaters and let me choose the best one for my needs. I'd recommend Comfort Defender to anyone looking for plumbing and HVAC service. I know I will use Comfort Defender in the future.”

“We had our old HVAC system replaced by David and his team. We were very impressed with how David took his time to explain everything beforehand, giving reasonable options with no hard sell. It was a much better experience than the last time we had our system replaced with a different company. The installation itself went smoothly and quickly. The team was polite and cleaned up well and we have noticed a huge improvement in the efficiency of our new system. We are very pleased with our experience and highly recommend Comfort Defender.”

“Last December the boiler in my rental went bad Idid not know that Dave worked on boilers and I asked him if he knew anybody that did and he said that he did, I had Dave help me with my ductless system a couple years ago and he did a great job. So I had Dave look at the boiler that was broken in my rental property, Dave looked at it and gave me an estimate for the new boiler and I agreed to it, Dave and his team replaced it all in ONE DAY. I left work early and was able to see him finish up the install and it looked great, nice and clean, He did an outstanding job and it was so fast it just blew me away. I can’t express how impressive and professional he and his team are, I was so impressed and thankful to him for his outstanding and quality work I couldn’t say thank you enough. Thanks Dave.”
