Dave is very friendly and responsive. He kept us well informed and did a great job. He recommended the system based on our needs, and we couldn't be happier. We have already recommended him to our neighbor. read less

On time each day and did an excellent job. Since I needed to get the attic and house ready with upgrades for electric etc. David talked with me about the other contractors needed and I'm sure none of the work would have gone as smoothly without his advice.Thank you David! read less

After a freezing night, I called around to find someone to fix it--including the contractors who had installed it--but no one seemed to think a lack of heat was a priority, so I couldn't get an appointment sooner than a week out. I saw David's positive Yelp and NextDoor reviews, so I gave him a call and he came right out! Texted me his ETA, showed up exactly when he said he would, and didn't even get upset when he found that the "broken" furnace had actually just been unplugged by the plumbers who had replaced my water heater a couple of days earlier. David is professional, friendly, and efficient; I will absolutely call him when I really do need HVAC service in the future. read less

No A/C at all. We hired Grumpy's to come in and look at everything. David Burnett showed up, talked through our options (lack of attic space for vents, etc.), and gave us options and estimates for each.We chose his recommendation, and it was installed on time and to budget. He left things clean and looking good. Can't recommend highly enough. read less

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. read less

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. read less

I couldn't be happier with David and the work he did for us after another company (Hussey Bros) massively screwed up the installation of our brand new, very expensive Mitsubishi system. David is responsive, knowledgeable and reliable. Showed up on time every day and worked with us on the final adjustments needed to make everything work perfectly. read less
