Jammon Comfort Systems is a Brockton HVAC company whose Thumbtack profile says it has operated for 37 years and handles furnaces, boilers, heat pumps, radiators, air-conditioning repair, and duct work. The profile lists it as a Top Pro and identifies Errol James in its background-check credential section. Five reviews posted from October 2025 through July 2026 describe prompt diagnosis and completed repairs involving oil furnaces, heating problems, a blower motor, and an air-conditioning issue. Reviewers mention quick appointments, staying until a problem was fixed, reasonable pricing, and choosing a blower-motor repair instead of recommending full furnace replacement. Before booking, ask for current license numbers and confirm the technician and estimate. Thumbtack lists an unrestricted master sheet-metal license and an oil-burner license, but publishes no numbers; those are directory claims rather than state-registry verification here. The profile is a fit for furnace, boiler, heat-pump, and related HVAC repair or maintenance.
Hal from Jammon comfort system came late in the afternoon and stayed until my problem with my air conditioner was working until it was fixed--Would hire again--Thank You--AK
Errol and Hans were such great guys: friendly, incredibly, hard-working, and, most importantly, honest. They diagnosed the problem within minutes, and I knew that what they told me was true. Price was more than reasonable.
Errol arrived on time and helped me get the oil furnace working again on the spot. Reasonable price as well. Highly recommend!
Errol is knowledgeable and very professional. He was able to fix the issue my heating in a very short time. I'm very thankful
Errol was responsive and we made an appointment quickly. He was the only one who didn't recommend replacing the entire furnace. We knew that the current issue was the need to replace the blower motor and his quote was very competitive. My HVAC system is back up, hopefully for many years to come. I'd recommend Jammon Comfort Systems.
