“Excellent service”

“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.”
