Heat Pump Service

Year-Round Comfort, Engineered for Here

Heat pumps are no longer a Southern climate technology. Cold-climate models from Mitsubishi, Daikin, Carrier, and Bosch are designed for Lake Superior weather, with rated heating capacity at minus 13 and continued operation below that. For Northern Minnesota homes, a properly sized cold-climate heat pump can carry the load through most of the year, with backup heat kicking in only on the coldest stretches.

Sizing matters more for heat pumps than for any other system. Get it right and you save 30 to 50 percent on heating compared to electric resistance, with bonus efficient cooling all summer. Get it wrong and you short-cycle, lose comfort, and pay for capacity you do not use. Northland Air does the heat-load calc, the cold-snap performance check, and the backup-heat integration before we recommend a system.

Warning Signs

Recognize Any of These Signs?

If any of these sound familiar in your home, it is time to bring in a licensed pro before a small issue becomes a major repair.

Outdoor unit covered in ice and not auto-defrosting

Defrost cycle failure. Cold-climate heat pumps should auto-defrost regularly. A frozen unit usually means a failing reversing valve, sensor, or refrigerant issue.

Blowing cool air when set to heat

Refrigerant low, reversing valve stuck, or auxiliary heat strips have failed. Each fault path is different. We diagnose with refrigerant gauges plus electrical testing.

Get an Estimate

Backup heat strips or furnace running constantly

Heat pump itself is not keeping up, or the thermostat is set wrong. Electric backup runs 2 to 3 times the operating cost of the heat pump, so this shows up fast on the bill.

Get an Estimate

System trips the breaker repeatedly

Compressor pulling too many amps. Could be refrigerant overcharge, a hard-start kit issue, or a compressor on its last legs. Diagnostic before the next start attempt.

Get an Estimate

Loud humming or vibration from the outdoor unit

Failing fan motor bearings, loose mounting hardware, or refrigerant restriction. Quick fix early, expensive if ignored.

Complete HVAC Services You Can Trust

Year-Round Comfort, Engineered for Here

Whole-Home Heat-Load Calc

We measure your home’s actual heat-loss, not a rule of thumb, so the unit we recommend is sized to your house, not your zip code.

Cold-Climate Model Match

We compare ratings at low ambient temps, not just nameplate capacity, so the unit we install actually delivers heat at minus 10.

Backup Heat Integration

Most installs include a backup heat source (gas furnace or electric strips). We size and wire the changeover so it kicks in only when needed.

Permit Pulled, Commissioned

Refrigerant charge, airflow, and electric load are measured and documented. You get the commissioning report.

Service FAQs

Common Questions About This Service

Quick answers to the questions homeowners ask most about this specific service.

A properly sized cold-climate heat pump will carry most Duluth winters with no backup, and the rest with a smaller backup source kicking in only on the coldest days. The key word is properly sized, which is why we do a real heat-load calculation on every install.

Upfront, cold-climate heat pumps cost more than a furnace. Annual operating cost is typically lower, often by 30 to 50 percent versus electric resistance and 10 to 25 percent versus mid-efficiency gas. Rebates and tax credits also currently apply on many qualifying units.

Yes. Federal tax credits and Minnesota Power rebates currently apply to qualifying cold-climate heat pumps. We track current programs and walk through what your specific install qualifies for at the estimate.

Yes. Ductless mini-split heat pumps are an efficient option for homes without ductwork, for additions, finished basements, or three-season porches. See our mini-split page for that specific install type.

We install Mitsubishi (Hyper Heat), Daikin (Fit and Aurora), Carrier (Infinity), and Bosch IDS, among others. We pick the model that fits your home’s heat load and budget, not the one with the highest commission.

In our climate many homeowners choose a dual-fuel setup, a cold-climate heat pump paired with a gas furnace that takes over in the deepest cold. It is the most efficient way to heat here and gives you a reliable backup on the rare day the heat pump cannot keep up alone.
