24/7 Emergency Heating, Cooling & Plumbing Service

No heat? AC down? Pipe burst? Gas leak? Call now: (508) 501-7424. We answer 24/7, 365 days a year.

When You Cannot Wait Until Monday

Some things do not happen during business hours. Furnace dies at midnight in January. Pipe bursts Saturday morning. AC quits during a July heat wave. You smell gas at 3am. These are real emergencies and we treat them that way.

Call (508) 501-7424 any time. Calls are answered around the clock, and emergencies get the on-call tech dispatched day or night. Our trucks carry common parts for heating, cooling, plumbing, and electrical so most calls are resolved same day.

Triangle covers four trades in-house. If your emergency involves more than one system, one call still handles it. No second company. No being told that is not our department. Serving Fall River, Swansea, New Bedford, Somerset, Taunton, and communities across SE Massachusetts and Rhode Island.

Why Homeowners Choose Triangle for Emergency Service

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.

What Our Customers Say

⭐⭐⭐⭐⭐They diagnosed a heating problem we had for over 20 years that no one else could figure out — including one of the guys from This Old House. They didn't give up until they solved it. The owner Tom is wonderful and Neil is a real gem!

⭐⭐⭐⭐⭐Donna is always so polite and accommodating. The technicians are knowledgeable and professional. We've used Triangle for years and wouldn't call anyone else.

⭐⭐⭐⭐⭐ AJ, Chad, and Tony did an amazing job on our church's HVAC system. Professional, clean, and on time. Triangle treats every job like it matters.

⭐⭐⭐⭐⭐ Called on a Sunday night with no heat. They had someone at our house within an hour. Fixed it on the spot. Can't ask for more than that.

⭐⭐⭐⭐⭐ We use Triangle for all our rental properties. One call for heating, plumbing, electrical — they handle everything. Makes my life so much easier.

Do you charge extra for after-hours calls?

Emergency rates are higher than standard. We quote the rate before dispatch.

How fast can you get to my home?

24/7 emergency dispatch across SE Massachusetts and Rhode Island. We give you an ETA on the phone.

What should I do while waiting?

No heat: check thermostat batteries, make sure it is set to heat. Water leak: shut off the main. Gas leak: leave the building, call 911 followed by us from outside. We walk you through steps on the phone.

What counts as an emergency?

No heat in winter, no AC in a heat wave, burst or leaking pipes, sewer backups, gas smells, electrical burning smells, and commercial refrigeration failures. If waiting until morning risks your safety, your property, or your inventory, call (508) 501-7424 now and we will treat it that way.

Are you really open on holidays?

Yes, 365 days a year. Furnaces do not check the calendar. We have dispatched techs on Christmas Eve, Thanksgiving, and the Fourth of July across Fall River, Somerset, and Tiverton. The phones are covered day and night, and emergency rates are quoted before anyone rolls.

Do you handle commercial emergencies?

Around the clock. Commercial contract customers get priority dispatch, day or night. Call (508) 501-7424 and tell us what is at stake.
