What customers said about heating system installation
Jensen Plumbing, Heating & Air, I…We have used Jensen Plumbing for several years. They respond quickly if they can, get the problem solved efficiently, and are reasonably priced. Glad to have them in town.
Jensen Plumbing, Heating & Air, I…Keith checked out our furnace a month ago. Did an awesome job in helping us pick out a new furnace since after 29 years we didn't want to push our luck through the winter! Monday the guys came and got the new furnace installed, new air conditioner as well as a new thermostat. I can't say enough good about this…
Jensen Plumbing, Heating & Air, I…The whole experience was absolutely wonderful. From the salesman down to the installers. Of course, as Luck would have it. It was a very rainy day when they did the installation. The installation looks absolutely beautiful and they definitely went above and beyond when they cleaned my Floor after they were done. Super kind and respectful group of men.
Jensen Plumbing, Heating & Air, I…Had a new furnace installed. Very professional, friendly, and high quality work! Both guys who did the installation were fabulous! Also thanks to Kenny! Great guy!!! Highly recommend Jensens!
Jensen Plumbing, Heating & Air, I…Superior service and professionalism which is extremely important to us. Well trained technicians. Prompt and very friendly. We are very happy with the sales and service. Nate & Matt did a great job today installing a new heating system in our garage. I would highly recommend this company. We use this company…
Jensen Plumbing, Heating & Air, I…Keith is the BEST when it comes to maintaining ALL our HVAC units here at the Avenue Square Mall. He knows our building, and he is honest and trustworthy. Thank you Keith for always taking such great care of us!
