Dave's Heating and Air Conditioning Service is a Winthrop furnace and heating business with 4.2 stars from 16 Google ratings. DAVID A. LEONARD holds Maine HVAC license MS30013847, active on the state registry. A 2023 customer whose furnace went out at 2am said he came out super quick and got the old furnace up and running again. A 2022 customer said Dave happened to be driving in the neighborhood when called, and after multiple service visits from another company had not resolved the issue, Dave found two issues and fixed them. A 2021 customer said the furnace went out at 1am and was fixed in 30 minutes; that 2021 customer also said the business did not accept debit or credit cards. A 2026 customer said Dave serviced the old furnace in a house they had recently purchased, and after a month or so the gasket around the oil filter was leaking. That 2026 customer said Dave later replaced the gasket and said it would be about $200 for the service, which they saw as an issue from his original visit. A 2023 customer said that when they called to schedule a service, they were told, "I am too busy for that."
Dave came to service our old furnace on a house we recently purchased. He was timely and professional and did the work efficiciently - four stars for ability. However, after a month or so, I noticed the gasket around the oil filter was leaking. I called Dave to let him know and he seemed very disinterested in the issue, though I reminded him that he was the one who worked on it, and it hadn't been leaking before. Dave gave me advice/directive to slightly tighten it myself and I did so. He was not interested in coming to address the concern and gave the impression of this call-back being bothersome. My wife called back another month or so later because the filter is still leaking. Dave agreed to come out and investigate it. He came and replaced the gasket. Then he told my wife it would be about $200 for the service. She was surprised since it was an issue from his original visit. She tried pointing that out, hoping he wouldn't actually charge $200 to fix an issue he created, but he was serious. As she was writing the check and discussing it, Dave said he could have replaced the entire canister for $250. My wife asked why he didn't just do that, and he said that since he'd done the initial work, it would be an additional $250 on top of the $200 for the work he'd already done. Insane. Why would you not lay out the options before you did the $200 gasket replacement for a $50 delta, instead of waiting until after? When my wife called Dave again later because she didn't like how it was handled, Dave basically said oh well to her feedback. Better luck with someone else. His feedback to her was that it wasn't leaking much - which apprently makes it fine.
10/10. Fast call out when our furnace stopped working in February. Kind, respectful and affordable. Thank you endlessly!
If there were 10k stars I would say Dave gets all of them. He was a savior!! Thank you so much for helping our family!! Samee & Mike Sage
When I called to schedule a service I was very disappointed by the rude response and being told, "I am too busy for that."
Absolutely amazing service! My furnace went out at 2am and he came out super quick and fixed it right up. I have an ancient furnace and was honestly expecting to be told I was SOL but he got the old girl up and running again! Super kind and very knowledgeable. Fixed problems left behind by the previous repair technicians. I would absolutely 10/10 recommend this business and will definitely be utilizing the services again when I update and replace my furnace in the summer.
