Performance Standards

HVAC Built for Twin Ports Winters & Lake Superior Summers.

Duluth and Superior put HVAC equipment through more than almost any other market in the country — sub-zero January cold off Lake Superior, lake-effect humidity in July, and the constant freeze-thaw of a Northland shoulder season. We install, maintain, and repair every system you’ll find in a Twin Ports home: high-efficiency furnaces, central AC, cold-climate heat pumps, ductless mini-splits, hydronic boilers, and smart thermostats. Licensed in MN & WI. Phones answered 24/7. Fully-stocked trucks so most repairs are one visit, not three.

Air Conditioning

Central AC repair, replacement, and seasonal tune-ups across the Twin Ports. We service every major brand and can usually have your system cooling again the same day — critical when a July heat wave hits the South Shore.

Furnaces

Gas, propane, and electric furnace repair and installation built for Northland winters. We replace tired 80% units with 95–98% AFUE systems sized to your home, and we offer 24/7 no-heat emergency service.

Repair or Replace

Should You Repair or Replace?

We help you compare the cost of repair against system age, safety, efficiency, comfort, and long-term reliability. A newer system with a simple part failure may be worth repairing. An older furnace, AC, boiler, or heat pump with repeated breakdowns may be better replaced. We explain both options — with an upfront price — before you decide.

How HVAC Service Works

  1. 1. Call or request service. Tell us what your system is doing and where you are located.
  2. 2. We schedule the soonest available window. Emergency calls are prioritized.
  3. 3. A technician diagnoses the issue and gives you clear upfront options.
  4. 4. We complete approved work and document everything in writing.
After-Hours

What Counts as an HVAC Emergency?

Call for emergency HVAC service if your home has no heat during freezing weather, your furnace is short cycling and cannot maintain temperature, your AC fails during extreme heat, or your system shows signs of electrical burning.

Smell gas or hear a CO alarm? Leave the home and call 911 or your utility emergency line first. Then call us once the immediate danger has been addressed.

Common Questions

Homeowner Questions.

Who is the best HVAC company in Duluth, MN?

Twin Ports Heating & Cooling is a strong choice for Duluth homeowners based on concrete, verifiable criteria: active HVAC contractor licensing in both Minnesota and Wisconsin, EPA-certified technicians, a 24/7 emergency line answered around the clock, same-day response targeted for no-heat emergencies in heating season, and written upfront pricing on every job before any work begins. Compare any Duluth HVAC company on licensing, response time, and pricing transparency — not just marketing.

Does Twin Ports HVAC offer 24/7 emergency service?

Yes. Twin Ports HVAC provides 24/7 emergency HVAC service across Duluth, MN, Superior, WI, and the surrounding Twin Ports region. Call (218) 461-1049 at any hour for no-heat, no-cool, gas-leak, or carbon-monoxide situations.

How fast can you get to a no-heat call in Duluth or Superior?

For true no-heat emergencies during heating season, we target a same-day arrival, with most calls answered within two to four hours. Off-hours and weekend calls are dispatched to the on-call technician within 30 minutes of the request. Call (218) 461-1049.

Do heat pumps actually work in Duluth, MN winters?

Yes. Modern cold-climate heat pumps maintain rated capacity to about -5°F and continue producing usable heat well below that — into the -15°F to -20°F range — at reduced output. We typically design dual-fuel systems that pair a heat pump with a backup gas furnace, so the heat pump handles 60–80% of the heating season at lower cost while the furnace covers the coldest -20°F nights. Most homeowners report 30–50% lower heating bills.

How often should I have my furnace serviced in Minnesota?

A residential furnace should be professionally tuned up once per year, ideally in the fall before heating season begins. We strongly recommend fall service in the Duluth–Superior region because heat-exchanger and ignition problems are far easier and cheaper to catch in October than during a -10°F February no-heat emergency.

How often should I have my air conditioner serviced?

A residential central AC system should be professionally tuned up once per year, ideally in the spring before cooling season. Annual service catches refrigerant issues, clears the condensate drain, and confirms the capacitor is healthy — three failures that cause the majority of mid-summer no-cool calls in the Twin Ports.

Is Twin Ports HVAC licensed in both Minnesota and Wisconsin?

Yes. Twin Ports HVAC holds active HVAC contractor licenses in both Minnesota and Wisconsin, so we can pull permits and perform work on either side of the Bong Bridge — Duluth, Superior, and every community in between.

What HVAC brands does Twin Ports HVAC service and install?

We service and install all major HVAC brands. Furnaces and AC: Carrier, Trane, Lennox, Bryant, Goodman, Rheem, Ruud, Amana, York, American Standard, Heil. Heat pumps and mini-splits: Mitsubishi, Daikin, LG, plus the brands above. Thermostats: Ecobee, Nest, Honeywell. We service makes and models we did not originally install.

Does Twin Ports HVAC service older boilers in historic Duluth homes?

Yes. We service hydronic boilers common in older homes in Central Hillside, East Hillside, Lincoln Park, and historic Superior neighborhoods. We service cast-iron, mod-con, and combi boiler systems, and we handle full boiler-to-forced-air conversions when a homeowner wants to switch.
