Twin Ports AC installation, repair, and tune-ups.
Cooling work built for short, intense Twin Ports summers. Honest sizing, clean installs, and tune-ups that actually catch problems before the heat wave hits.
What we cover.
We install, repair, and tune up central air conditioners across Duluth, Hermantown, Superior WI, Two Harbors, and Cloquet. From a quick capacitor swap on a 90-degree afternoon to a full new-construction system, we keep the price clear before we start.
Sizing matters more than brand. An oversized AC short-cycles, leaves humidity, and dies young. We do a real load calc, look at your duct sizing, and right-size the system to your house, not to the easiest sale.
Signs you need air conditioning service.
If one of these is happening at your house, do not wait. The longer you run it, the more it costs to fix.
Warm air from the vents
Frozen coil, low refrigerant, failed compressor, or a tripped breaker. All worth a same-day diagnosis.
AC runs constantly
Usually undersized for the home or has a dying capacitor. Either way it is wasting power and shortening compressor life.
Loud or grinding outdoor unit
Fan motor, bearings, or a contactor on the way out. Catching it early avoids a full compressor failure.
Water pooling near the air handler
Clogged condensate drain. Easy fix today, expensive ceiling damage if ignored.
Higher power bill, same usage
Dirty coils, low refrigerant, or a system at the end of its life. A tune-up will tell us which.
System is more than 12 years old
Modern high-SEER units can cut cooling cost by a third. Time for a side-by-side quote on repair vs replace.

Why homeowners pick Northland Air for air conditioning.
Real load calculations
We do not eyeball tonnage. We measure your home and size the system to it. That is how you get full life out of an AC in Duluth's short summer.
Clean line sets
Every refrigerant line we run is brazed, pressure-tested, evacuated, and supported. No kinks, no leaks, no callbacks.
Warranty we honor
1-year labor warranty on top of the manufacturer's parts coverage. If it is our work, we stand behind it.
What homeowners say about our air conditioning work.
We had three quotes for a new AC. Northland Air was not the cheapest, but they were the only one who actually looked at our duct sizing and our load. The install was clean, on time, and our power bill dropped 18 percent.
Brands we service and install: Trane · Carrier · Lennox · Goodman · Mitsubishi · Daikin · Bryant
The math behind a right-sized AC.
The single biggest predictor of long AC life in the Twin Ports is correct sizing. Oversized units short-cycle, leave humidity, freeze coils, and die young. Undersized units never catch up on a hot day and run themselves into the ground.
| Home size | Typical AC size | SEER target | Approx install |
|---|---|---|---|
| 1,000 to 1,500 sq ft | 2.0 ton | SEER 15 to 17 | $4,500 to $6,500 |
| 1,500 to 2,000 sq ft | 2.5 to 3.0 ton | SEER 16 to 18 | $5,500 to $7,800 |
| 2,000 to 2,800 sq ft | 3.0 to 3.5 ton | SEER 16 to 18 | $6,800 to $9,500 |
| 2,800+ sq ft / dual zone | 4.0 ton or two zones | SEER 17 to 20 | $9,500+ |
Real sizing depends on insulation, window area, sun exposure, and ductwork condition. We do a Manual J at the quote, not a square-footage shortcut.
Air Conditioning questions, answered.
Most full residential central AC installs land between $4,500 and $9,500 installed, depending on tonnage, brand, and how clean the existing ductwork is. We give itemized quotes in writing so you can compare apples to apples.
Most straight swap-outs are done in one day. Full ducted-system rebuilds can take two to three days. We confirm the timeline at the quote so you know what to expect.
Yes, we service all major brands. We do not care who sold it to you, we will give you an honest diagnosis and a flat-rate repair price.
Schedule a tune-up in spring before the first hot stretch. Catching a low capacitor or weak fan motor in May beats an emergency call in July.
Usually yes. Replacing a 12-year-old system with a modern high-SEER unit typically cuts cooling cost 20-35 percent. We can show you the math for your home.
Yes, Minnesota and Wisconsin require permits on all new HVAC installs. We pull every permit our work requires, included in the quote.
