Who We Are

Not a Franchise Script — Just Grantsburg Techs

What you're actually getting when you call.

HVAC Repair CO isn't trying to be everything to everyone — we fix and install HVAC equipment in Grantsburg and Grantsburg, WI, and that's the whole business. Every technician on staff is licensed, background-checked, and EPA 608 certified to handle refrigerant legally — 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 Grantsburg, 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 Grantsburg 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

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

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

WARNING 06

One Room That's Never Comfortable

Often a duct or damper issue, not the equipment itself — fixable without replacing anything.

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

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

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 where there shouldn't be ice is a diagnostic flag.

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

Single-family homes and Grantsburg 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 Grantsburg 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 Grantsburg 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 Grantsburg 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 Grantsburg 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

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