"We called David at 7:30am when our furnace died, and he had it replaced and our home totally cleaned by 5:30pm! Knowing we went back to CT the next day, he stopped by to be sure the new install was functioning properly. He also installed a WiFi thermostat and has been extremely helpful in programming it. We're so glad we found him! "

"From start to finish, David, Dave Jr. and Dustin did a professional and excellent installation of our new Viessmann Vitodens 222 propane condensing boiler. David explained EVERYTHING about the system and made sure we were comfortable with it after the installation. We have had it for over a month now, it is perfect. Follow up from David has been great! We HIGHLY recommend David Aaskov & Sons for your plumbing and heating needs."

"I am so pleased with the service from David Aaskov and Sons and would highly recommend them. This team is very friendly and respectful, they do meticulous work and they demonstrate exemplary professionalism! When I called to ask for a quote for a failing oil broiler, David came over and did a very thorough evaluation. He explained what he saw as he went. He also made sure to evaluate the property and ease of access while he was there. Within a day I received a very detailed quote. David offered replacement of the oil broiler and oil tank in phases to help with budgeting. I decided to have it all done at one time which was a 3 day project. David worked with me to find a time in my extremely busy schedule to do the job. They finished today and everything went so smoothly. They even took care of a few extra jobs that I needed done while they were here. I want to highlight that they were very respectful of my property and they left it cleaner than it was when they came. They also fixed up some sloppy plumbing that was done by the previous owner. During the entire process they communicated how things were going and kept me well informed on the progress. Having contractors in your house for 3 days can be stressful, but not David and his sons. They were very efficient and friendly and didn't make any unnecessary noise. After the installation was completed, David showed me everything and offered to return in a week or so to make sure everything was working fine. During the payment process Paypal was giving us some challenges. David was very calm and not bothered a bit that we had to call both Paypal and my credit card to troubleshoot which took a fair amount of time. I could go on and on with positive remarks about David and his sons. I will definitely hire them again!"

"We are so pleased with our experience with David Aaskov & Sons. We needed a new furnace. David came to our home within two days and gave us detailed information and advice on both oil and natural gas furnaces, He gave us references to call. After we decided to choose David Aaskov and Sons for the work, he was on site within a week, and made all arrangements with the gas company. The work was done promptly with great customer service the whole way. He took time to explain everything, and even took care of the entire rebate process through Summit Gas and Efficiency Maine. I would recommend David anytime."

"My wife & I were looking or someone to install a new propane gas boiler heating system in our home. We were having a difficult time getting information and price quotes from one company. I talked to many people and a UPS driver, Chuck, suggested that I get in touch with David Aaskov. David Aaskov had done work for him and Chuck was very impressed. I soon gave David a call one morning. David came to my house that afternoon to look over the job. David gave me a detailed price quote within two business days. I received other quotes, but not very detailed and not very timely. I asked a number of questions from David, mostly via email, and David answered every one in a timely manner. David was patient and understanding, knowing that I didn't know anything about the heating system that I was looking to install. When David came to my house he explained how and where things would most likely be installed. I was impressed with the information, the care and time that David put into explaining everything. When I went to his business to make a deposit and accept his business, he showed me a system that was installed and explained how it would work. He also stated that on demand hot water could take a little time to be hot after you turn it on. After the system was installed, my wife believes that we get hot water sooner than our old system. Yes, there is a delay, but it is not that long. Everything that David said he would do, he and his team did them. David came when he said he would, he took the time that he said he would. After the Viessmann propane gas boiler system was installed he and his men took the time to go over everything and explain how everything worked. Not only did David install the heating system, but I asked if they had time to do a few water system items. David and his men said yes and also installed some new water pipes, repaired some water pipes and made our water system more efficient. I could write a number of other things that are all positive, but I will end by saying that not only are David, his son David, and Dustin very efficient in their work, but they treat you in a friendly manner. I would highly recommend that anyone have David Aaskov do any of the work that they do."

"I was increasingly convinced my 50 year old oil fired furnace needed replacing. It wept water from between the boiler sections, needed a new controller and was generally unreliable. I was unsure of the condition of the oil tank, as well. Once I made my mind up that now is the time to do something I Googled the Energy Maine website and located David Aaskov and Sons on their list of approved installers. My wife’s friend had strongly recommended David. She had suffered a freeze while she was in Florida and she was effusive about his work and his manner. I called David and he came to inspect my heating system the next day. I was inclined at first to simply replace the oil burner and, possibly, the tank. David suggested another possibility was to replace the system with a Veissman 100 Propane condensing boiler. This is a wall mounted unit a fraction of the size of my oil furnace. My cellar is inclined to be wet, so I like the fact that the unit is wall mounted. There didn’t seem to be a great difference in cost between replacing all the oil components or switching to the Propane burner. I applied to Energy Maine for a low interest loan and upon approval went ahead with the installation. It took 2 ½ days to install. David’s crew is polite, industrious and considerate. They installed a complete working system for the price quoted and did not nickel and dime me for extras. Their workmanship is immaculate and they carted off the old 900 lb boiler and oil tank and left my cellar debris free. I am very pleased with the whole heating replacement process. "

" After dealing with 3 companies for 4 days, I submitted my name on this website. David called and came over that same day which was a Saturday. He sent me a quote on Sunday so I could send it to Efficiency Maine before Monday. He and his workers came over on Monday to take the mess of pipes and old furnace down off the wall. Mind you a large company replaced a large furnace with a wall model 11 years prior and left pipes cut and hanging. On Tuesday at 9 am David's worker showed up to start installing the new Viessmann 100 at 9 am. At 6pm when I got home from work, I had heat, hot water and full water pressure I didn't even know was wrong. David and his workers went above and beyond to make the new furnace look very organized, functional, safe and clean. Now I have a white wall with a white furnace, shiny new pipes and a gas line that goes along the ceiling. In addition to the installation he cleaned and conditioned all the pipes in the baseboards so there is no corrosion etc in the pipes. He replaced the unbonded gas line which was just hanging from the furnace behind my washer and dryer to the outside wall. He checked the hot water and found the pressure was off between faucets, so he changed my filter. When that didn't fix the problem he replaced two parts on my well water tank. He also called my gas company and had them replace a part on the tank that was leaking. I couldn't have asked for any better of a job. They did all this with only going over a quote I received to just change out the broken furnace with a newer model by $800. When considering I now have a better quality furnace, all new pipes by the furnace, new gas line and 2 new parts on my well. I believe I got a great deal. I would recommend them to everyone. "

"In February 2016, our service technician informed us that our System 2000 (installed in 1988) boiler was damaged beyond repair and leaking propane into our house. We temporarily moved out of the house and I went into high-speed research mode to find the right boiler system and technician to install it. I received a couple of quotes from some well-known HVAC companies in the greater Portland area, but my wonderful, detective mother-in-law read nothing but excellent reviews about David Aaskov on Angie's List and Efficiency Maine's websites. I called David and informed him of our situation. David was tremendously responsive and wanted to see the boiler setup immediately. I informed him that I would be home the following day and he showed up as promised. David provided me with a quote for a Viessmann 200 that evening and was ready to install the new boiler the following day! His quote for the Viessmann 200 was a $4,000-$5,000 less expensive that his competitors. David and his son were at the house the following day, as promised, and had the new boiler installed the next day. They were very professional and I highly recommend you contact them for any heating or plumbing need, or in our case, emergency. "
