Furnace repair

No heat, or a furnace making an awful noise? Maxon finds the problem fast and fixes it, often the same day.

AC repair

Dead fans, failed capacitors, and units that run but don’t cool. Same-day visits are common.

Furnace & AC replacement

Swap out a worn-out system for a new furnace and AC, with the options and price laid out before work starts.

Mini splits

Ductless heat and AC for homes, cabins and commercial spaces, including Samsung units. Quiet and efficient.

Tune-ups & check-ups

Annual system check-ups before winter and AC tune-ups in spring, so small problems get caught early.

Ductwork & heat runs

New heat runs and fixes for rooms that need better airflow.

Thermostats

Thermostat problems sorted out, including smart thermostats like Ecobee.

New construction

HVAC systems for new builds. Call to talk through your project.

Repair or replace?

Straight answers, even if the answer is “fix it”

Old system acting up? Maxon explains what’s actually wrong, what each option costs, and lets you decide. If a repair makes more sense than a new system, he’ll tell you.

Questions

Good to know

Do you really come out at night and on weekends?
Yes. 24-hour service is painted right on the van, and customers have called at 3:30 a.m., late in the evening, on Sundays and on the July 4th weekend.
Do you charge to come diagnose the problem?
Ask when you call. One recent customer summed it up: “Its true, free diagnostic!”
My system is old. Should I replace it?
Not always. Maxon will walk you through the repair and replacement options and what each costs. Plenty of customers have kept an older unit running when a repair made sense.
Do you install mini splits at cabins?
“I had Denning Heating & Air install a Mini Split Heat/AC unit at a cabin. They did a terrific job with great workmanship and they were very clean.” (Marlin, Google review)
Are you licensed and insured?
Yes. Denning Heating & Air is licensed, insured, and certified.
