Why Choose Triangle?
In-House Electricians
Most HVAC installers sub out the panel work. That means two companies, two schedules, two invoices. Our own electricians handle the panel work. One company, one invoice.
Mass Save Participating Contractor
We know which systems qualify, what documentation the program requires, and where homeowners usually lose money by picking the wrong equipment tier. We confirm your eligibility before you spend a dollar.
55 Years. Not a Startup.
Rebate money brought a lot of new companies into this market. Triangle has been at 425 Pleasant Street in Fall River since 1970. When your compressor needs warranty service in 2030, we will still be here.
Four Trades, One Company
Getting a mini split and notice the water heater looks rough? Want a generator quote while we are there? Heating, cooling, plumbing, electrical, refrigeration. One call, one truck, one bill.

Yes. Triangle is one of the only contractors in southeastern Massachusetts with licensed HVAC, plumbing, electrical, and refrigeration techs on the same team. For a homeowner, that means one call instead of three when a job crosses trades, like a heat pump that needs a panel upgrade. One crew, one schedule, one invoice. We have worked this way since 1970.
