Who We Are

A Greenwich Crew That Answers Its Own Phones

The short version of who shows up at your door.

We do one thing in Greenwich: HVAC repair and installation, done right the first time. 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. The number we say is the number you pay, 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 say the cheap fix out loud, even when it costs us the bigger sale.

Know the Warning Signs

Six Signs Your Greenwich 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

Dirty coils, low charge, and leaky ducts all quietly drive up runtime before anything actually breaks.

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

Usually mold or mildew building up in the ductwork or on the evaporator coil, worth addressing before it affects air quality.

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 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

Core Hvac Services in Greenwich

The full scope of Greenwich 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

Single-family homes and Greenwich condos get the same diagnostic-first process whether it's a $150 repair or a full system swap — 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 Greenwich 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

Leaky ductwork in a Greenwich attic or crawl space can waste a large share of conditioned air before it reaches a vent, and we test and seal as part of a full evaluation.

SERVICE 07

Smart Thermostat Installation

Smart thermostat installs start with a compatibility check, 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 Greenwich 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

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