Reviews

  • "Ken installed a new boiler system a couple of years ago and boy, are we happy! He installed a new manifold that allowed each zone to operate independently, and more importantly, if one of the zones gets a leak, the other zones can continue to operate. We experienced a real cold spell over Thanksgiving last year and one of the pipes burst from the cold. Thankfully, the other zones kept the house warm and snug until he could move the pipe away from the wall and replace it. No more worries about frozen pipes! He also installed a new water heater for us as well. Ken also installed a new air conditioning system for us. Because we have a boiler, we only had window units in the past. Not only was this hard on the windows, it is getting hard on us too! Plus, we have to store five window AC units in the basement each year, so that was a pain. Ken devised a system where the air handler and the vents are installed in our attic and the condenser installed outside. It is wonderful to be able to flip a switch and have cool air! We feel that Ken has been honest with us, and given us good guidance. He is very quality conscience, and he doesn't leave a mess at the end of the day. He is a really good guy and we heartily recommend him!"

  • "Ken was wonderful. We have been having issues with our A/C unit. A previous company replaced the blower motor . 3 days later the a/c was blowing but not cold. He came out within a day or so to check it out. He was able to repair within just a few days! He had also found a piece of copper pipe stuffed in another pipe. He was surprised any air flow was coming in. He was early to the appointment. Very professional and reasonably priced! Thank you Ken for making our house much more comfortable and safe!"

  • "I've already used Ken a few times since buying the new house and have absolutely no complaints, Ken most recently replaced my water heater and the guy is always professional, quick, and efficient. He'll always answer any questions you have and will never rush. Will definitely continue to use his services- great guy!"

  • "In an earlier review of work done on our own house, I mentioned that we have recommended Ken Hansen to several friends. We recently called him for a replacement to an aging furnace at my mother's house. He provided a very reasonable quote and got the installation done, complete with a new thermostat and humidifier with very little turnaround time. We were so pleased to have my mother in his capable hands. And she may actually be able to read this new thermostat - an unexpected bonus."

  • "Ken have been our technician for more than 10 years. I feel really great about having a company that cares about their customers. I was so pleased with the services he provided for us and with the thorough inspection done on my old furnace. Once again thank you so much for everything.”

  • "We contacted Ken when our air conditioner was acting up. He kept the dinosaur running while he provided us with quotes and options that were far more reasonable than anyone else to replace our old unit. Ken came out and installed a new air conditioner and thermostat when he promised. He’s prompt, professional, courteous and friendly. I’d recommend him to anyone looking for any HVAC work that needs to be done. Thank you for a great experience and for keeping our home cool through the recent heatwave."

  • "My Furnace and A/C units were old and inefficient. Hansen Heating and Cooling was very patient with me in answering my questions and getting me set up with new units of good quality and at a very fair price. I was surprised with how quickly the install went. Ken did a follow up visit to make sure the system was running well and to check that I was happy with the work. Hansen H&C stands by their work. We later had a problem with the system not running right, but Ken was able to diagnose the problem and have the defective part changed out within 24-hours. The service all fell under warrantee and was at no cost to me. I highly recommend Hansen Heating and Cooling."

  • "Ken is great! We had him install two humidifiers and couldn't be happier. He set us up with a system that is low maintenance and has been trouble free since install. Best Heating and Cooling Company around!"

    Andy P.

  • "Ken installed a Mini Split System that we were able to purchase online and he was extremely professional and easy to work with. He came highly recommended from both friends and family and I could not be happier. There are closer HVAC companies but none will give you the attention you deserve....when you need it. BTW, I also called him on an emergency call on another unit, and he was "Right On It"! Could not ask for better customer service.

  • "Ken was honest, reliable, affordable, and found a problem that we have been trying to solve for years with no avail with other services. He is THE BEST and will be our only go to guy from here forward!! Thank YOU Ken!!"

  • "Mr.Hansen was so nice and kind and really loved the service he provided for me! It’s hard to find someone who is honest and trustworthy! He will be my go to hvac professional for me and family!"

  • "Ken from Hansen Heating and Cooling, installed 2 condensing units on the roof of our condo building. He also installed the coils on the indoor units to match. The job was very professional and the attention to detail was second to none. We needed to use a crane to lift the new units onto the roof and the old one down and the coordination was seamless. I would recommend Hansen Heating and Cooling whether you need a new install or need service on your existing equipment. Ken explained the scope of work prior to starting and gave us an excellent price as well."
