Signs your furnace needs a look

  • It won't turn on

    The thermostat calls for heat and nothing happens, or the burners light and shut off a few seconds later.

  • Rooms never get warm

    The furnace runs and runs, but the house stalls a few degrees short or some rooms stay cold.

  • Short cycling

    It starts and stops every few minutes, which wears out parts and wastes gas.

  • New noises

    Banging at startup, squealing from the blower or a rattle that wasn't there last winter.

  • Rising gas bills

    Higher bills without colder weather usually means the furnace is working harder than it should.

  • Age and repairs

    A furnace past 15 years that needs a repair every season is worth a repair-or-replace conversation.

Repair or replace: how we help you decide

Most furnace calls end with a repair. Some don't. Either way, you get a straight answer about what failed and what it makes sense to do about it.

What usually causes no heat

Most no-heat calls trace back to a small set of parts: a dirty flame sensor, a failed igniter, a blocked condensate drain on a high-efficiency furnace, a pressure switch, or a control board. A clogged filter causes more problems than people expect, because the furnace overheats and shuts itself off for safety.

We test each part before we name a problem. Swapping parts until the furnace runs is how a simple repair turns into an expensive one.

When replacement makes more sense

If the heat exchanger is cracked, the furnace is near the end of its life, or repairs are piling up year after year, putting that money toward a new furnace is often the better deal. We'll price the repair and the replacement side by side so you can decide with real numbers.

As an independent American Standard dealer and a Mitsubishi Electric Diamond Contractor, we're not locked into pushing one product. If a heat pump or a ductless system fits your home better, we'll say so.

What to expect on the visit

A technician checks the thermostat, venting, filter, gas supply, ignition sequence and safety controls, then tells you what failed and why. If we have the part on the truck, most repairs happen the same visit. Before we leave, we run the furnace through a full heating cycle to confirm it works, and we follow up afterward to make sure it held.

What affects the cost

Repair cost depends on the part, whether it's in stock, and how hard it is to reach. Replacement cost depends on the size and efficiency of the furnace, any changes to venting, ductwork or gas lines, and whether you're adding air conditioning at the same time. We quote the work before we start.

Common questions

Don't see yours? Call and ask. A real person answers.

My furnace won't turn on. Is there anything I should check first?

Make sure the thermostat is set to heat and its batteries aren't dead, the furnace switch is on, the breaker hasn't tripped and the filter isn't clogged. If it still won't run, call us. Don't keep resetting it.

Do you repair furnaces you didn't install?

Yes. We repair and maintain all makes and models, not just the brands we sell.

Do you offer emergency furnace repair?

Yes. Our phone is answered 24 hours a day, 7 days a week, including weekends and holidays.

How long does a furnace last?

Many last 15 to 20 years with regular maintenance. Age alone isn't a reason to replace one. Repair history, efficiency and the condition of the heat exchanger matter more.

Which areas do you serve?

Stillwater and Washington County, MN, plus St. Croix County, WI and the towns along the river valley.
