Who We Are

Not a Franchise Script — Just Dartmouth Techs

What you're actually getting when you call.

HVAC Repair CO isn't trying to be everything to everyone — we fix and install HVAC equipment in Dartmouth and Dartmouth, MA, and that's the whole business. Every technician on staff is licensed, background-checked, and EPA 608 certified to handle refrigerant legally — there's no gray area on that.

A recurring story from new customers: a phone quote that didn't match the invoice. The number we say is the number you pay, and that's true whether it's a $150 capacitor or a full system.

Word of mouth is how this business grows in Dartmouth, which keeps every technician honest — a bad call travels fast in a community this size. We say the cheap fix out loud, even when it costs us the bigger sale.

Know the Warning Signs

Six Signs Your Dartmouth System Needs a Look

Catch these early and the fix is usually smaller.

WARNING 01

Warm Air From the Vents

Three different causes, one diagnostic visit to tell them apart.

WARNING 02

Grinding or Squealing on Startup

Noise on startup is a clue, not a death sentence for the unit.

WARNING 03

A Bill That's Climbing With No Reason

The system works harder long before it fails outright.

WARNING 04

Short-Cycling or Running Nonstop

Either pattern wears down components ahead of schedule.

WARNING 05

Water Near the Indoor Unit

A clogged condensate line backs up fast and can damage flooring before you notice a comfort issue.

WARNING 06

One Room That's Never Comfortable

Ductwork is the usual suspect here, not the unit.

WARNING 07

A Musty Smell When the System Runs

A musty odor on startup points to moisture somewhere in the system.

WARNING 08

The System Is Older Than Fifteen Years

Aging equipment tends to fail at the worst time — a proactive look can flag whether replacement planning makes sense.

WARNING 09

Strange Odors From the Vents

A sharp electrical smell or a rotten-egg odor both call for shutting the system off and getting it looked at quickly, not wait and see.

WARNING 10

The Outdoor Unit Is Covered in Ice

Ice where there shouldn't be ice is a diagnostic flag.

WARNING 11

Rooms Feel Humid Even When It's Cool

Sticky air despite a cool thermostat reading usually means the system isn't running long enough to pull moisture out.

What We Do

Core Hvac Services in Dartmouth

The full scope of Dartmouth work we take on.

SERVICE 01

Emergency Repair

Total no-heat or no-cool gets same-day dispatch, day or night — a real person answers the line, not a voicemail loop, answered by an actual dispatcher, any hour.

SERVICE 02

Residential Repair & Installation

The approach doesn't change based on the size of the job — test first, quote second, always.

SERVICE 03

Commercial HVAC Service

Downtime costs businesses money, so commercial accounts get moved to the front of the line.

SERVICE 04

Indoor Air Quality Upgrades

Air purifiers, humidity control, and filtration upgrades for Dartmouth households dealing with allergies or general air quality complaints — purification, humidity, filtration.

SERVICE 05

Preventive Maintenance Plans

A twice-yearly tune-up catches a failing capacitor or dirty coil before it turns into an emergency call, which is almost always the cheaper path.

SERVICE 06

Ductwork Sealing & Repair

Duct problems quietly waste money long before anyone notices, and we test and seal as part of a full evaluation.

SERVICE 07

Smart Thermostat Installation

A thermostat upgrade is one of the cheapest efficiency improvements available, and we check compatibility with your existing Dartmouth system first, not guesswork.

SERVICE 08

Heat Pump Service & Repair

Reversing valve, defrost cycle, and auxiliary heat all need specific diagnostic steps a general repair call doesn't cover, not treated like a standard split system.

SERVICE 09

New System Installation

A real Manual J load calculation before recommending equipment size, not a square-footage guess, so the new Dartmouth system performs the way it's rated to.

SERVICE 10

Static Pressure & Airflow Testing

Real measurement tools replace guesswork on comfort complaints.

SERVICE 11

Commercial Rooftop Unit Service

Dartmouth businesses running packaged rooftop units get the same diagnostic rigor as residential split systems as anything else we service.
