Comfort can't wait. Neither do we.
No heat in January. No AC in July. Both are emergencies in the Northland. We run 24/7 emergency service: a real person answers every call and we dispatch the same night. A licensed tech arrives with parts on the truck and a flat-rate price before any work starts. No surprises, no excuses, just the problem fixed.

Our furnace died the night before a snowstorm. Three other shops couldn’t come for days, these guys had us back on heat in four hours flat.
Sarah K., Duluth, MN
Honest about what was actually wrong with the water heater. Saved us $1,200 over the big-name shop’s quote, and the install was cleaner too.
Tom B., Cloquet, MN
Pipes froze at -20°F on a Sunday. They were here in 90 minutes, thawed everything safely, and even insulated the worst run before they left.

Frequently Asked Questions
Straight answers about service, pricing, and emergencies, no jargon.
Are you licensed and insured in Minnesota?
Yes. We carry a Minnesota HVAC contractor license, plus full liability and workers’ comp coverage on every job, for your protection and ours.
Do you give upfront pricing?
Always. You see the full quote before any work begins, no hourly billing surprises, no add-ons mid-job.
Do you offer financing?
Yes. We offer flexible financing through approved lenders on qualifying installations, so you can move forward with the right system and spread the cost over time. We go over current options and terms when we quote your job.
Do you offer same-day or emergency service?
Yes, we run 24/7 emergency calls for no-heat, no-water, and burst pipe situations. Most other calls are same-day if booked before noon.
Do you service Duluth and the rest of the Twin Ports?
Yes. We serve a 60-mile radius from Duluth — including Superior, Hermantown, Cloquet, Two Harbors, Carlton, Grand Marais, and everything in between. We also serve the Ely area and the surrounding Iron Range communities. One company, one standard of service, across the entire region.
How does your estimate and consultation process work?
New installs and replacements include an in-home consultation where we assess your home, size the system properly, and give you an all-in, upfront price before any work begins. Our $139 diagnostic covers the full estimate — no travel charges, no hidden fees, no surprises. If you move forward with the work, the $139 rolls into the job.
Do you charge a diagnostic fee?
Yes. Diagnostics start at $139, which covers the on-site visit and a written quote. If you book the repair or install with us, that $139 rolls into the job. No hourly billing surprises, no mid-job add-ons.
How does your pricing work?
Flat-rate, upfront. You see the all-in price for the work before we touch a wrench. For larger installs we also walk through annual operating-cost differences between options so you can make a real decision, not a guess.
What kind of warranty do you offer?
Every install carries a 1-year labor warranty on top of the manufacturer parts and compressor warranties. We document the work with photos and combustion / pressure readings on every job, so if anything is off, we have the records to make it right.
Do you pull permits on installs?
Yes, every install. Permits pulled, inspections passed, and full commissioning documented. You get the paperwork. If anyone tries to talk you out of permits to save you a few dollars, get a second opinion.
