Who We Are

A Madison 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 Madison and Madison, SD, 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.

We got tired of hearing the same complaint from new Madison 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.

Word of mouth is how this business grows in Madison, 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

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

The system works harder long before it fails outright.

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

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 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

Everything We Handle, No Sub-Contracting

The full scope of Madison 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

The approach doesn't change based on the size of the job — 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

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

SERVICE 06

Ductwork Sealing & Repair

Duct problems quietly waste money long before anyone notices, 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

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 Madison 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

Rooftop equipment gets the same careful approach as anything else we service.
