• Very knowledgeable, great prices, gives you every option possible to figure out your issues. Very thorough and very professional. Highly recommended

  Matias F.★★★★★

• I have dealt with Don Weimer Heating and Air Conditioning for the past 30+ years. I have always found him to be fair and honest in his treatment of his customers. I recently found myself in need of his service regarding the failure of my furnace and air conditioning system. He provided me with a honest assessment of my current system and what would be required for repair. He also provided me a quote on a new system that would more closely meet the capacity required for my home. I found him to be a no pressure and honest individual who provides high quality service at a reasonable price. I would recommend Don to anyone. Based on the age of my old system and the repairs that would have been required, I went with the install of a new furnace. He pre tested the furnace prior to install. The Install was completed in one day with total clean up. He followed up after the install to be sure there were no issues, of which there were none. Great Job Don Weimer Heating and Air Conditioning Update 12/5/2025 I continue to be pleased with Don Weimer HVAC. I was having a minor issue with my furnace. Service arrived in less than 12 hours from the time I called and routine maintenance was performed and I am up and running. Still extremely pleased with Don and his son Stephen Weimer.

  Blake C.★★★★★

• Steve has been great to us! He came out and fixed our boiler same day. It was in the 20’s and other companies were quoting multiple day waiting periods. Yesterday our A/C went out and he came this morning and fixed it. The customer service is excellent and he takes the time to explain the work he’s doing and ways to prolong your equipment. Definitely recommend

• I called them for an estimate and they came out the next day. I made my decision to go with them because they were very thorough in explaining the product and what I needed, and the cost. They scheduled an installation a few days later. I highly recommend them. They are very known and easy to work with.

  Joyce B.★★★★★

• Thank you for coming out on a short notice to check and install my new water heater tank.

  elena E.★★★★★

• Don Weimar Heating & Air installed a new furnace for us and did a great job! Steve and his team were knowledgeable, efficient, they cleaned up after themselves, and were very respectful, polite, and friendly. They were able to do the job about a week after their initial visit/consultation. It was a pleasure doing business with them!

  bill L.★★★★★

• Recommending to everyone I know! Another company did a cleaning/tune up on my tenants boiler and insisted I need to replace it asap. The next evening the heat suddenly stopped working. I called Steve, explained to him what was going on and he said "I'll be there tomorrow morning." He came in, diagnosed the issue, and fixed what was needed to keep things running well. Explained what was going on and what he was doing to fix it. He pointed out things that may need to be addressed in the future, but did not aggressively try to sell me on an expensive job. Steve is honest, knowledgable, and friendly. He will forever be my go to for any heating and cooling issues or improvements!

  Kyle M.★★★★★

• Steve Wimer is incredibly thorough and very kind. Ultimately he installed a new tankless water heater, but he also successfully addressed many other issues I had. He is very understanding, and both he and his team are welcome here anytime!

  John J.★★★★★

• I first had Air Conditioning installed by Don Weimer and so pleased to have his son Steve install a new furnace. Steve and his team were so thorough in diagnosing my old furnace, and determined it was beyond economical repair. They came back the following day to install a new furnace, and instructed me how to operate new thermostat and furnace. We are very happy with our new system. Our house is very comfortable and furnace is more efficient than our old one. I highly recommend Steve and his team, they are a great business to work with!

  Gregg C.★★★★★

• They are very thorough and just great... just love them...

  Carleen G.★★★★★

• Great business First of all two things that don’t happen in today’s world 1st-Steve answered the phone , no voice mail and waiting for a return call days later. 2nd -Steve and Dave were at my home within 24 hrs. To find figure out the problem and make the repairs.

  michael S.★★★★★

• Steve the owner and technician did us a great service at my home. He reworked my controls on the furnace and the whole house is getting even heat throughout for the first time in a long time. Great service and fair pricing.

  Pat D.★★★★★

  Patrick Y.★★★★★

• I called last minute on a Friday, during a heat wave,and they did their absolute best to help me out, and they did. They explained what they were doing each step of the way and were very efficient with their time! Good job, fair pricing, and great customer service! Highly recommend them!

  Suzi S.★★★★★

• I've got a guy for that! I've trusted Don with my family's comfort and safety for twenty plus years now. I wish I could give more than five stars...THANKS DON

  Billy B.★★★★★

• Highly recommend. Steve (Don Weimer's son) showed up to check an underperforming AC unit. He quickly diagnosed the problems and offered solutions and costs upfront. We ended up deciding to replace our AC unit (was 28 years old). Steve walked us through the best value for our situation. Steve was professional, responsive and kept us informed throughout the process. From our initial service call to having a new unit installed was only a few days. Great to see a second generation business and Steve serving the business and his customers so well. I had no referral or connection to this company previously, but was very pleased. We will use Weimer's for all our HVAC needs in the future!

  Brian L.★★★★★

• Person who takes their calls is extremely rude and condescending. Had a CO concern due to two alarms going off in separate rooms, needed someone as soon as able to check on furnace etc. Called first thing in morning but no answer, did not leave voicemail. They called back 10mins later and before asking what I called about proceeded to give a lecture on how I was rude for not leaving a voicemail. Explained my situation and was chastised again for not immediately explaining fire dept came out as well. Never have done business with them and never will.

  Kevin T.★★★★★

• They were very helpful and prompt in the fixing of my furnace... and thankfully too bc the temp in the house got down to 55⁰!

  Teresa L.★★★★★

• There are good people, great people, fantastic people, out-of-this world people...and then there is Don Weimer and his crew!!! Did an outstanding job, came out the same day to check out are problem, fixed it promptly, and called the next day to make sure everything was ok. Five stars isn't enough!!!!
