See what some of our customers have to say about our exceptional customer service:

Bruce A. “Derrick, you installed my Mitsubishi air conditioning and heating unit, my gas hot water heater, and my gas hot water furnace boiler. All of your work was done in an efficient and professional manner. You cleaned up your work area, there were no call backs for repairs, and the price was right. My jobs were not easy to do as my house is well over 100 years old and nothing is level- except your piping! Thanks again for a job well done-“:
From Jon B. “After purchasing a large commercial building several years ago, it became obvious that it had numerous HVAC problems, at which point I was referred to Derrick (Synergy Heating and Cooling) as the most qualified in the area to help me. He came in, spent days going through the whole system, found more than a dozen problems (primarily caused by the previous contractor) and rectified the situation. I have the utmost confidence in his abilities from that experience and numerous others thereafter, in both commercial and residential HVAC applications. I’ve always felt he treated me fairly, and I highly recommend him.”
Spencer and Carols willingness to keep right on top of the job till done. Very good to see. Kurt H.
Jim & Deb A. “We are completely satisfied with the service Mr. Ellefson provides us. He is very competent, knows his trade at the highest level. He is also very courteous and tries his best to take care of any problems in a timely manner. Also his honesty is beyond reproach. We highly recommend Derrick Ellefson.”
“For years we have been looking for the perfect solution to cool our studio space during our summer season of fiber art classes and we finally found in with Synergy. The Mitsubishi units that create a climate controlled space for our students to work in made a huge difference immediately. We can have 12 or more students in the studio during mid-summer who not only want to keep themselves cool, but could be creating additional heat by using irons, heat-set fabric and fleece dyes, etc. Spinners, knitters, and others who work with and are surrounded by wool also appreciated a complete change in their working environment. As a business, we want to make our customers comfortable and happy. In a matter of hours, this was accomplished with the capability and skill of Synergy. We are so pleased with the way the units work and the personal attention from Synergy. We’ve already heard from some of our students who are excited about the improved studio experience. Thank you, Synergy!”
John & Dorothy G. “Since many heating and air conditioning people are not conversant with geothermal equipment, we were pleased that Synergy Geothermal, in the person of Derrick Ellefson, was not only knowledgeable, but also able to make convincing comparisons about the various makes and models on the market. After choosing the make we thought best, the Water Furnace residential unit appropriate for our house, Derrick quickly got it ordered and efficiently installed. We were very pleased with his courtesy, demeanor, and knowledge. We would be happy to recommend him and his company to all.”
Very impressed. Arrived early, very knowledgeable, and did a great job. What more could I ask for. Dawn & Eva W.
Carolyn F. “In one day, Synergy took our home, warmed it, and moved it forward years from an old, rumbling furnace to quiet efficiency! I appreciated the way the work was done and the extra time explaining the workings of the system. Synergy made the whole experience easy- from straightforward information, to clear expectations, to completing the project in a timely fashion, to following up at the end, and all done in a friendly, competent manner with a smile!”
Dudley & Mary R. “We are pleased to give our highest recommendation for Synergy Heating & Cooling and for the work and service. Synergy installed a new heating/cooling system for us in 2012: prior to that Derrick did other service work for us. He is exceptionally knowledgeable, careful and competent in his work and very fair in his pricing. He does the work in a timely manner and is thorough in his clean up and follow up. We are impressed by his experience and by his awareness of the latest technology in his field. It has always been a good experience to have him in our home.”
Mike S. “When shopping to replace an entire HVAC system for my house Synergy floated to the top. Many local companies quoted the job. Synergy was close to the best value but not the bottom quote. However the knowledge Derrick brought fourth an the care taken in determining the system allowed Synergy to float to the top and secure the job. They were excellent during the installation and everything worked as advertised. Later I had Synergy back to install some advanced filters on the system. Again the experience was positive. As a final point, Derrick and the team showed up when they said they would. This was a problem for many of the other contractors I called to quote my system. They either showed up late or not at all. Hire Synergy you won’t be disappointed.”
JR J. “I can’t say enough about the help I got from Synergy Heating & Cooling. They were punctual, did a great job.“
