"I feel fortunate to have been able to meet Chris and have him fix my HVAC issues. He was prompt, excellent at communicating, and also is a great listener. The cost of my service wasn't low due to what was needed but it was more affordable than other quotes I'd recieved; some of the others who had spoken to me on the phone were indicating rates that were 50% higher than what Chris charged for the same exact product! I'll gladly hire him for future work. I've already given his number to others with HVAC needs."

"I wanted to clean a second floor dryer vent hose that was loaded solid with lint. It was worse than I thought! Packed solid! It became evident that this was a messy and dangerous situation as it was a fire hazard. Through Angi I found Everclean and the co. was a perfect fit. HVAC companies don’t do dryer vents. Justin from Everclean was awesome and got the problem straightened out. He even discovered the dryer vent had become disconnected from outside dryer vent door! I can’t fit through the narrow attic hatchway as my shoulders are a bit too wide, so I depended on Justin. Finally, everything is buttoned up, and our clothes now dry in half the time. Cost was moderate and was money well invested. Dryer vent fire danger is now negligible compared to before. Along with neighbor hatred danger. I would hire Everclean again if needed again."

"I needed an HVAC company for both my heat pumps. for house and garage shop. I looked on Homeadvisor and found Bill Aitken Heating. Thank you Homeadvisor! Bill was not only professional, but friendly and courteous. He explained everything he was doing right down to how the newest equipment he used. Bill was very thorough checking out my HVAC system. I will need to look no further for a contractor due to Bill's excellent work. I highly recommend Bill."
