Who We Are

Not a Franchise Script — Just Granville 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 Granville and Granville, 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.

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 Granville, which keeps every technician honest — a bad call travels fast in a community this size. 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

What we tell Granville homeowners to watch for.

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

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 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

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

Single-family homes and Granville 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

Beyond heating and cooling, we handle the air quality side too — 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 Granville 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 Granville 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

A real Manual J load calculation before recommending equipment size, not a square-footage guess, so the new Granville 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

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