Who We Are

Not a Franchise Script — Just Sullivan Techs

The short version of who shows up at your door.

We do one thing in Sullivan: 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. 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 say the cheap fix out loud, even when it costs us the bigger sale.

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

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

WARNING 02

Grinding or Squealing on Startup

A specific noise usually means a specific part — bearing, belt, motor mount — not a system that needs replacing.

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

Both extremes stress parts that are cheaper to fix now than after they quit entirely.

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

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

Older systems are worth a checkup before they force the decision.

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 Sullivan

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

Sullivan businesses can't afford climate control going down mid-shift — commercial calls get priority scheduling and rapid routing, so commercial accounts get moved to the front of the line.

SERVICE 04

Indoor Air Quality Upgrades

Beyond heating and cooling, we handle the air quality side too — purification, humidity, filtration.

SERVICE 05

Preventive Maintenance Plans

Seasonal maintenance catches small issues before they become expensive ones, which is almost always the cheaper path.

SERVICE 06

Ductwork Sealing & Repair

Leaky ductwork in a Sullivan 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

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

SERVICE 08

Heat Pump Service & Repair

Heat pumps get their own diagnostic approach, not treated like a standard split system.

SERVICE 09

New System Installation

Sizing starts with an actual calculation, so the new Sullivan 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.
