Reduced heating or cooling
The system runs constantly but never reaches the set temperature. Often low charge, a dirty coil, or a failing reversing valve.

Signs it's time to call
What a heat pump sounds like before it fails
Grinding, squealing, rattling
Bearings, fan blades or a loose panel. Catch it early and it's a small part; ignore it and it takes the motor with it.
Schedule repairShort cycling
On, off, on, off every few minutes. Thermostat placement, an oversized system, or a sensor fault — all fixable.
Schedule repairHigher bills, same weather
A sudden jump in the electric bill without a cold snap usually means the system is working harder than it should.
Maintenance plansWater or ice where it shouldn't be
A clogged condensate drain indoors, or ice that never clears outdoors. Both are quick fixes if you don't wait.
Frozen coils guideMusty smell on startup
Biofilm on the indoor coil or drain pan. A deep-clean fixes it; a maintenance plan prevents it.
Why it smells
Repair vs. replace
The $5,000 rule
Take the age of the system in years and multiply by the repair quote. If the answer is under $5,000, repair it. If it's over, the money is usually better spent on a new system — especially now, while NYS Clean Heat rebates (confirmed at the free estimate) and 18-month 0% financing are on the table for cold-climate heat pumps.
We'll show you both numbers. If a Mitsubishi heat pump isn't the right fit for your house, we'll say so — we also install RUUD furnaces and central air, boilers, and water heaters.
Questions homeowners ask us
My heat pump is running but the house is cold. What should I check first?
Filters (clogged filters are the number-one cause), the outdoor unit (buried in snow, iced over, or blocked by a snowbank), and the remote's mode — it's easy to leave it in Fan or Dry. If those are clear and it's still short, call us. Our Mitsubishi troubleshooter walks you through the blink codes too.
Is it normal for the outdoor unit to steam or stop in winter?
Yes. In cold, damp weather the outdoor coil frosts, and the unit periodically reverses for a few minutes to melt it — you'll see steam and hear the indoor fan pause. That's a defrost cycle, not a fault. Ice that never clears, or a solid block under the unit, is a service call.
Should I repair or replace?
Multiply the system's age in years by the repair cost. Under $5,000, repair is usually the right money; over $5,000, look at replacement and the rebates that come with it. A $350 repair on a 5-year-old unit ($1,750) is a repair. The same $350 on a 15-year-old unit ($5,250) is a conversation about a new system.
Do you repair heat pumps you didn't install?
Yes — Mitsubishi and other brands, ductless and ducted, across our service area. Our technicians are Mitsubishi-certified and carry genuine parts. Systems from other brands sometimes need parts ordered.
Do you offer emergency service?
Our service line is (518) 683-0889 during business hours. After hours, the 24/7 support line at (518) 333-7431 is an AI technician that walks you through troubleshooting, and dispatches or schedules a technician. Maintenance plan customers go to the front of the line.
What does a diagnostic visit cost?
There's a trip and diagnostic charge for non-contract customers, quoted when you book. Preferred plan customers pay no trip charge; Superior Shield Elite customers pay nothing for the visit, parts or labor.
