Sousa's Oil Burner Service puts in and services oil burners, oil tanks and furnaces. A recent customer said the company put in a new oil tank and furnace, cleaned up every day after the work, and took out and disposed of the old system. Maine's registry shows hvac license MS30009967 active on the state registry, with JOSEPH SOUSA SR as holder of record. On its website the company says it offers 24/7 emergency service. A 2026 customer whose burner kept starting and stopping said Sousa's fit them in 2 days later, and that Bruce did a thorough cleaning and service of the heating system and explained everything he was doing. A 2024 customer said that after the furnace "died," Joe and Bruce came the next day, and within three days the customer had a new oil burner, oil tank and an updated hot water tank. A 2021 customer said Joe and Bruce installed a new furnace, replaced the plenum and many of the ducts, removed two oil tanks and installed a new oil tank and thermostat. A 2023 customer said Bruce was responsive and quick when they needed emergency service on their furnace on a Saturday. A 2022 customer with a low water shutoff problem said "this guy" was booked out a week or so but helped walk them through the fix on the phone, and the call did not cost anything. A 2023 customer said "Big Joe" would not service the property unless the customer spent 6k, and that the fix ended up costing 90 bucks for a motor replacement online. A 2022 customer who said Sousa's had maintained their boiler and oil-fired hot air furnace without an issue said that when the garage furnace quit on a Friday, the company did not call back until Sunday afternoon and refused to sell them ignition electrodes off the truck, citing liability; that 2022 customer said the company did offer to do the work for a weekend service call charge.
Just had this great company put in a new oil tank and furnace. My old one was a gob job by others. Sousa’s are by fair the best guys you’ll ever have in your home I would not hesitate to have them for my oil furnace needs they are most certainly very professional, trustworthy guys, cleaned up every day after their work, took out and disposed of the old system as well. I have a safe and reliable system now. Can not thank them enough! Especially with the oil prices to have an efficient heating system is a must!
I purchased my home a couple years ago and procrastinated on getting a cleaning and service on my heating system, and the company that the former owners used had retired (one man with a van), so I did some research on local oil burner service companies on Google. I knew I needed an appointment fairly quickly because my burner was acting up - starting and stopping for the first couple minutes of every heating cycle and a smell of incomplete combustion. After calling around to some of the local burner service companies and not really having much luck getting an appointment, I talked to Sousa's and they were able to fit me in 2 days later. Bruce showed up first thing in the morning and did a thorough cleaning and service of the heating system, explained everything he was doing, and after all the work was done, the system is running in perfect shape now. He was very friendly throughout the entire time he was here, he is very knowledgeable and has a professional customer service attitude and I can tell he cares about giving customers an overall pleasant experience. It has been about a month since the work was done, and my heating system continues to "purr along in tip top shape" which gives me the confidence of a worry-free burner and boiler system going forward. And I will definitely make sure to get an annual cleaning going forward! I highly recommend Sousa's Oil Burner Service if you're looking for an overall high quality service, that leaves you with the peace of mind your system will work efficiently and effectively.
Great service thank you very professional and knowledgeable
Bruce is always on top of his stuff! Genuine people here. Always will recommend
Sousa Oil is an exceptional company! My furnace "died" and my oil tank and hot water tank were old and outdated as well. I called Joe, and he and Bruce came the next day to replace everything. Within three days I had a brand new oil burner, oil tank and an updated hot water tank. They were fast, knowledgeable, and provided superior service! They were happy to answer all my questions and left my basement clean. I highly recommend them for any heating concerns.
