Who We Are

Not a Franchise Script — Just Plaistow Techs

The short version of who shows up at your door.

HVAC Repair CO isn't trying to be everything to everyone — we fix and install HVAC equipment in Plaistow and Plaistow, NH, and that's the whole business. Licensing, background checks, and EPA certification aren't optional for anyone we send out — there's no gray area on that.

A recurring story from new customers: a phone quote that didn't match the invoice. So our pricing is flat and written down before a wrench touches anything, full stop, and that's true whether it's a $150 capacitor or a full system.

Referrals are how we grow here, so cutting corners isn't worth the reputation hit. We'd rather tell you a $200 fix solved it than talk you into a system you didn't need.

Know the Warning Signs

Don't Wait for Total Failure

Catch these early and the fix is usually smaller.

WARNING 01

Warm Air From the Vents

Refrigerant leak, failing compressor, dirty coil — all different fixes, all confirmed with a gauge before we quote anything.

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

Standing water usually means a blocked drain line, worth catching early.

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

Certain smells mean stop running the system and call, not wait and see.

WARNING 10

The Outdoor Unit Is Covered in Ice

Ice on the condenser in cooling season points to airflow or charge problems, not something to just wait out.

WARNING 11

Rooms Feel Humid Even When It's Cool

Humidity and temperature are two different problems.

What We Do

Everything We Handle, No Sub-Contracting

From a 2am emergency to a full replacement.

SERVICE 01

Emergency Repair

No-heat and no-cool situations jump the schedule, 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 Plaistow 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 Plaistow 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

Sizing starts with an actual calculation, so the new Plaistow 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

Rooftop equipment gets the same careful approach as anything else we service.
