An HVAC Company in Detroit That Takes Winter Seriously
Frost Fighter HVAC Detroit was named for the job we get called for most: getting heat back into a Detroit home when the furnace gives up in the cold. From October through April, furnace repair is the heart of what we do.
We service gas furnaces of every vintage, from standing-pilot units to high-efficiency models that vent out the side wall. Our trucks carry common parts so many repairs can be finished on the first visit.
When summer arrives, the same crew takes care of air conditioners, heat pumps and thermostats, so you have one number to call all year.

Frequently Asked Questions
My furnace turns on and off every few minutes. Is that a problem?
Yes. Short cycling wears out parts and wastes gas. A clogged filter, dirty flame sensor, overheating or an oversized furnace can all cause it, so it's worth having it checked.
What can I do while I wait for no-heat service?
Close curtains, shut doors to unused rooms, open cabinet doors under sinks on outside walls and use space heaters safely. Never use the oven or a grill to heat the house.
How long does a furnace usually last?
Most gas furnaces last about 15 to 20 years with regular maintenance. Past that point, breakdowns usually become more frequent.
Do smart thermostats work with every system?
Not always. Many need a common wire, and multi-stage or heat pump systems need the right settings. We confirm compatibility before installing.
Should I cover my AC condenser in winter?
Covering just the top can keep ice and debris out, but wrapping the whole unit can trap moisture. Never run the AC with a cover on.
Can you add central air to a home that only has a furnace?
Often, yes. If your ductwork is in decent shape, we can add an outdoor condenser and an indoor coil on top of the furnace.
Still unsure what's wrong? Describe it to us on the phone.
Call (313) 000-0000Common HVAC Problems in Detroit, MI
These are the issues we run into again and again in Detroit-area homes.
Frozen furnace exhaust and intake pipes
High-efficiency furnaces vent through PVC pipes on the side of the house. Snow drifts and ice can block them and shut the furnace down.
Standing-pilot furnaces past their prime
Plenty of Detroit basements still have decades-old furnaces with standing pilots and worn thermocouples that fail on the coldest nights.
Heat pumps stuck in defrost
Freezing rain and wet snow can coat outdoor coils. If the defrost controls fail, the unit ices over and heating drops off.
Overworked AC during humid heat waves
Long stretches in the 90s push older condensers past their limits, and failed capacitors and fan motors are common in July.
Uneven heat in two-story homes
Upstairs rooms often run cold because of undersized returns and leaky ducts in older homes, not just a weak furnace.
