AC Repair

When the air conditioner quits during a Minnesota heat wave, Maddox sends an AC repair technician to Minnesota the same day, often within hours.

Air Conditioning Installation

A new central air conditioner or ductless mini split, sized right for a Minnesota home, cuts cooling bills and ends the summer of repair calls.

Heating Repair

No heat in Minnesota in January is an emergency, and Maddox treats it like one.

Furnace Repair

Furnace repair in Minnesota is what we do more than anything from October through April.

Furnace Installation

A new 95–98% AFUE gas furnace installed by Maddox can cut a Minnesota heating bill by a quarter or more compared with a 20-year-old 80% unit.

HVAC Repair

Maddox is a full-service HVAC company serving Minnesota with same-day heating and cooling repair, installation and maintenance.

Heat Pump Repair

Cold-climate heat pumps are the fastest-growing heating and cooling choice in Minnesota, and Maddox repairs, services and installs them: Mitsubishi, Daikin, Fujitsu, Carrier, Bosch and more.

AC Tune-Up

A spring AC tune-up in Minnesota is the cheapest way to avoid a summer breakdown.

Before the first freeze in Minnesota, have Maddox give the furnace a full tune-up: burner and flame sensor cleaning, heat exchanger inspection, gas pressure and CO testing, ignitor and blower check, filter change and a safety-control test.
