J Gasper Heating and Air Conditioning

On the Better Business Bureau, J Gasper Heating and Air Conditioning describes itself as offering heating, air conditioning service and installation as well as oil, gas and sheet metal, and its website claims 25 years in business. Its Connecticut heating and cooling licence, HTG.0388499-S1, held by J GASPER HEATING - AIR CONDITIONING CO, is active on the state registry. Its BBB grade is A+. A 2025 customer who lost heat in an oil furnace said they left a message at 7 pm on a Friday, and the owner called back in 5 minutes and walked them through restarting it over the phone. A 2024 customer said a technician came out within hours to clean out an oil tank that had run dry from gunk build-up, and that their oil burner was replaced with a Beckett within an hour. That 2024 customer named the owner as Jim and described it as a family company, with the wife doing the office work and a son as a technician. A 2023 customer of about 15 years said John, the technician, cleaned their furnace at their new house, cleaned a clogged pipe to the chimney, and stopped a loud banging in the pipes and radiators; that 2023 customer also said Gaspar was the least expensive of the quotes they got. A 2023 customer listed a new oil tank, a new A/C installation and a new furnace among the work done for them over the years. A 2022 customer said Mark Gaspar serviced their heating system in slightly over an hour, explained the work and cemented the duct to the chimney. A 2021 customer said Jon Gasper showed up on time and serviced the furnace, after a wait for a non-emergency appointment. A 2025 customer said boiler cleaning and a new split system went well, but when they needed a new boiler, "he said he had to leave it behind for a couple of weeks"; ten months later that 2025 customer still had a 700lb. block in the basement and got excuses when they called. A 2023 customer called both members of the family-run business rude and the service very slow. A 2022 customer said a diagnosis took a month, the fix was quoted at three weeks or more, they were out of hot water for a month, and the woman handling phone calls was unprofessional.
