Heating Repair
Our NATE-certified technicians provide 24/7 emergency heating repairs for furnaces, boilers, and heat pumps. Using state-of-the-art diagnostic tools, we identify and resolve issues with ignition systems, heat exchangers, and thermostats. Our repairs extend system longevity while optimizing energy efficiency for Minnesota winters.
Cooling Installation
We install Carrier central air conditioning and ductless mini-split systems with precision-engineered components. Our installations maximize energy efficiency while ensuring proper sizing for your home's square footage. Technicians follow manufacturer specifications to maintain warranty validity and system performance.
Plumbing Services
Our licensed plumbers handle emergency leak repairs, water heater replacements, and gas line installations. We specialize in addressing frozen pipe emergencies and water softener installations tailored to Minnesota's hard water conditions.

We contacted Tonna for information regarding replacement of our water softener. Clint came to show us what they have to offer.
Clint showed us the three softeners they carry and explained what the differences were and also the benefits of each. Good information and no pressure to decide on the spot. Now we have to decide.
