Nimmer customer service was excellent! Easy to schedule an appt. and the technician that came out was thorough, walked through some of the things he saw as he inspected the furnace and answered all my questions. Would highly recommend to others!

We’ve always had excellent experiences with Nimmer. Their prices were fair, customer service excellent, and we’ve gotten really quality home products with them when it was time to replace our major appliances. Natalie was our most recent service tech and was excellent! Friendly, professional, never felt like we were being oversold and even caught/replaced for us some outdated parts from a prior year’s installation. We will continue to trust and use Nimmer for our home!

Blake was great. He explained everything to me and was very professional. I would call him a definite “Keeper” for your company. When my Blower arrives I hope he is the one to put it in.

Nimmer Heating and Air was recommended by another service company that we had used for years before they got out of the HVAC business. We’ve used Nimmer twice so far, once for our A/C unit and this most recent time for our ancient boiler. Both times we’ve been so thankful to have found them. Technician Blake was friendly, prompt, and informative. I inquired about their maintenance plan and he didn’t try to upsell me— he gave me the facts and a brochure for me to make the decision on my own timeline, no hard pressure tactics which I really appreciated. I also appreciate the kindness and professionalism of the office staff who have been helpful both times. Nimmer will continue to be our go-to for all of our HVAC needs.

DO NOT USE❗️Beth and front desk informed me my service charge would be $89 for diagnostic the tech stated it’s a new system as it is. Nothing was done and the tech Blake stated new filter was needed and that was it. $89 charge turned into $190 randomly. Apparently their $89.50 labor charge for the techs time qualifies for a “repair”. Now that the tech has left and my furnace is running as it’s has been not only am I still hearing the motor fade in and out the home is starting to smell burnt when the heat comes on not even 3hours after they left, as Beth the receptionist stated the tech “checked the wires and made sure they were good”.
