Fantastic group of people. Estimates were fast and offered a better heating solution than the competition. The work was fast, professional and courteous. We had a minor issue with a noisy fan and there was a technician onsite within a couple of hours. He didn't find anything (of course the noise stopped just before he arrived), but he still thoroughly inspected and did some preventative maintenance - we haven't had the issue again.

Report
We had a furnace cleaning service performed. The evening after the service, my wife smelled gas. I was traveling, so I could not confirm this myself. A couple days later she had a friend over and when they went into the basement they smelled gas quite strong. My wife called a gas leak company. They told he to cal 911. The fire department came and sniffed the basement with a meter and found a leak at the incoming gas line to the furnace.
They shut off the gas, wife called Christensen's emergency repair phone and a stinky man from some company came out to repair. My problem is that Christensen is well aware of this repair since they have to pay the repair call. And did not make a call to us with an apology for putting my wife into this position because of their poor service. All we needed was a phone call.will not use this company again.

Christensen Heating and Cooling put in our air conditioning units about 15 years ago when the previous owners lived here. Our home is 1910 and never had air before then. After living here for 4 years, we called to have them clean and service the machines; we have 2 units, 1 to cool the upstairs and 1 for the main floor. We initially had some mishaps with a couple of the service professionals. Then Andy came to the house and made things right!
He did a fantastic job! The owner Mike came to our house today to address the mishaps and we are beyond pleased with his professionalism and response to o the issues. He's owned the company for over 30 years and that just doesn't happen without the proper management of your business! Thank you Mike and Andy for all you have done for us! Looking forward to a continued relationship!

I called and asked for a specific duct work design to be done so I could use it as a laundry shoot. They gave me the email to send my idea over. They had it made in less than a week and ready for pick up. They made sure it was to my liking and price was reasonable. I thought it was expensive but I asked my friend who works in HVAC and they said it was totally accurate for what I wanted. They were quick, respectful and made exactly what I was looking for! I will definitely use their service again in the future.

Excellent customer service! Our furnace technician came quickly within just a few hours of my placing a call for service. He was very professional, reassuring, very knowledgeable and quickly retrieved the filter that got sucked into the furnace(we either waited too long to change or it was the wrong size) and performed a furnace tune-up afterwards at a VERY reasonable price. I am a customer for life! Thank you Rick and Thank you Christensen Heating & Air Conditioning!
