    Thank you David!

    We hired David to fix a flaky furnace on the home we just moved into. He arrived on time and was very methodical in his debug process. After two hours work, the furnace works flawlessly. Just so you know, we checked YouTube for the symptoms, and NONE of the videos showed the correct answer. All the YouTube videos pointed to a dirty flame sensor, none pointed to clogged combustion tubes. That's what experienced guys like David are for. Service: Heating system repair

    I am a plumbing contractor who has been using David and Grumpy's HVAC for the last 6 years and I have had nothing but rave reviews from the clients I have referred him to, along with my own personal experience with him hiring him as a sub contractor. He is always on time, is efficient in his work, and it is always beautifully completed. If you want an experienced, professional, contractor you can trust Grumpy's is your only place to go. Services: Thermostat installation, AC maintenance, AC installation, Thermostat repair, Duct and vent installation, HVAC maintenance

    We called Grumpy's to replace the 70-year-old gas furnace in our new-to-us house. David came by, discussed our options, gave us a very reasonable quote, and three days later we had a brand new mini split heat pump system! This thing works great and I'm very glad we went with Grumpy's.
