When an intake water tank burst on a Saturday morning and flooded the basement, a recent Google customer called David, and by noon he had found them a new tank and had the pipe repaired. That customer said he also advised them on the rest of the home's aging plumbing. David Aaskov Inc. says on its website that it has been in business 49 years and names Gray, Naples, Raymond and Windham as its service area. The site lists heating, A/C, plumbing, boiler and radiant, heat pump, ductless mini-split and water heater service. Its BBB page shows an A+ grade. A 2026 customer said their Biasi boiler quit a few days before Christmas because of a stuck valve, and that Dave helped them select a Viessmann boiler as the replacement. That 2026 customer said he put in long hours, even on the New Year's holiday, to get their hot water and heat back up. A 2023 customer said Dave came the next day, and that their oil burner was replaced with a propane system in two days; that customer also got a new heat pump hot water heater, and he removed the oil tank. A 2023 reviewer wrote that David and his team installed a natural gas forced hot water system, a forced hot air unit and a heated driveway for them. A 2025 customer said a Daikin mini split installed about five years earlier developed a warranty issue and was leaking water. That 2025 customer initially had some trouble connecting with anyone, but David got back to them and said the issue would be taken care of at no cost, and the unit was rebuilt to replace the defective part.
Our intake water tank burst on a Saturday morning, flooding the basement. We called David, sent him pics of the broken pipe and tank, and by noon he found us a new tank and had the pipe repaired. Fast, efficient, friendly, and even advised us on the rest of our home’s aging plumbing with his years of knowledge. Thank you so much for your help!
A few days before Christmas our Biasi boiler quit due to a stuck valve that Biasi no longer supports. Dave patiently helped us navigate this frustrating so well and helped us figure out that a new boiler was our best option. Dave helped us to select a Viessmann model 100-B1KE-120 - excellent boiler. He is an incredibly nice guy and a straight shooter. His communication was excellent throughout. He put in some long hours even on the New Years holiday to get our hot water and heat back up. It’s rare to see this kind of service anymore. Thank you Dave - highly recommend.
I had a Daikin mini split installed about 5 years ago. David was here within a day or two of quoting the work and was here until it was finished. After about 5 years the indoor unit had a warranty issue and was leaking water. I initially had some trouble connecting with anyone but eventually David got back to me and assured me they would get the issue taken care of at no cost to me. They were here the following day to diagnose the problem and after the parts were in, they came and promptly rebuilt the unit to replace the defective part.
Our oil furnace was down to 77% efficiency. I knew how knowledgeable and professional David Aaskov was from the year my daughter and SIL needed a new heating system and I had researched options and contractors for them. David helped them with a new system and my SIL always speaks so highly of him and Viessmann, one of the main brands David uses. So, I called Dave. He came the next day. He discussed all the options with us and we decided to replace our oil burner and go with propane. His estimate came in very quickly and we hired him The work was done in two days and the system is beautiful, quiet and efficient. We also got a new heat pump hot water heater. He removed the oil tank as well. You will be in able, excellent hands if you call David . I highly recommend him.
David and his team have installed multiple systems for me, including a natural gas forced hot water system, a forced hot air unit, and even a heated driveway! I have referred them to clients who have also reported being very happy with their work. These guys are pros, they hustle, and they're just nice guys and therefore pleasant to work with.
