Who We Are

A Sullivan Crew That Answers Its Own Phones

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 Sullivan and Sullivan, IL, 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.

We got tired of hearing the same complaint from new Sullivan customers: the last company quoted one price on the phone and a different one at the door. 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 Sullivan System Needs a Look

What we tell Sullivan homeowners to watch for.

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

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

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

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

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

What We Do

Everything We Handle, No Sub-Contracting

The full scope of Sullivan work we take on.

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

Single-family homes and Sullivan 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

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

Air purifiers, humidity control, and filtration upgrades for Sullivan 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 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

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 Sullivan system performs the way it's rated to.

SERVICE 10

Static Pressure & Airflow Testing

Manometers and anemometers measure what's actually happening in the ductwork instead of guessing from symptoms on comfort complaints.

SERVICE 11

Commercial Rooftop Unit Service

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