24 hour furnace repair in Aurora, CO for a furnace that quits in the middle of the night, on a weekend or during a cold snap. Meadowood Furnace Repair is open 24 hours, 7 days a week.
Most no-heat calls after dark come down to a short list: a furnace with no power, burners that will not light, a furnace stuck in lockout after several failed starts, a high efficiency furnace that shut down because its pipes iced over, or a heat pump whose backup heat never came on. Each one has a fix at the furnace.
Emergency Furnace Repair in Aurora for No Heat
- No power: furnace switch, breaker, blown control fuse, door safety switch, failed transformer
- No ignition: cracked igniter, dirty flame sensor, gas valve, control board
- Lockout: repeated failed starts from a draft, flame or pressure switch fault
- Blower faults: dead blower motor or capacitor, so the furnace overheats and shuts off
- Frozen or blocked intake and exhaust pipes on 90 percent furnaces
- Frozen condensate lines and traps that trip the pressure switch
- Heat strip and sequencer failures on heat pump systems
When a Furnace Problem Is an Emergency
In this part of Aurora a dead furnace in January is more than an inconvenience. NOAA normals for the Centennial Airport station show about 5 nights a year at or below zero, and the National Weather Service lists a 24 below reading in Denver as recently as December 22, 2022 (Denver record low temperatures). A house with no heat on a night like that can freeze water lines in exterior walls, crawlspaces and garages.
A burning electrical smell from the furnace, a furnace that keeps tripping its breaker, water pouring from a condensate line, or no heat at all on a freezing night are all reasons to call at any hour.
Snow, Ice and High Efficiency Furnaces
Many furnaces in Meadowood, Mission Viejo and Summer Valley have been converted to 90 percent units that vent through PVC pipes on a side wall or the roof. Drifting snow and frost can close those pipes, and the furnace shuts down on its pressure switch. Condensate lines that run through a cold garage or crawlspace can also freeze. Clearing a pipe fixes the first case. The second needs the line thawed and rerouted or protected.

24 Hour and Emergency Furnace Questions
What is considered a furnace emergency?
No heat when it is freezing outside, a furnace that keeps tripping its breaker, a burning electrical smell, water leaking from the furnace, or repeated lockouts. Any of these is a reason to call without waiting for business hours.
Is a broken furnace an emergency?
In an Aurora winter, usually yes. A house can lose heat quickly on a night in the teens or below, and water lines along outside walls are the first to freeze. On a mild fall night it can often wait.
When to call emergency HVAC?
When the house has no heat in freezing weather, when the system is leaking water or tripping breakers, or when a part is clearly burning or failing. Problems like a noisy blower or one cold room can wait for a regular visit.
Why would my furnace randomly stop working?
A safety switch opened, the flame sensor stopped proving flame, the filter clogged enough to trip the high limit, or the vent pipe iced over. Intermittent faults like these often show up on the coldest nights, when the furnace runs longest.
What can I do if my furnace won't turn on at all?
Check that the thermostat is set to heat and has fresh batteries, the furnace switch near the unit is on, the breaker has not tripped, the blower door is fully closed so its safety switch is pressed, and the filter is not clogged. If all of that checks out, the fault is inside the furnace.
Why is the furnace not kicking on?
No call for heat from the thermostat, no power to the furnace, a blown fuse on the control board, or a furnace in lockout after failed starts. A board with a flashing status light can narrow it down.
What would cause a furnace to have no power?
A tripped breaker, a furnace switch that was turned off by mistake, a blown fuse on the control board, a failed transformer, or an open door safety switch.
Why does my furnace keep shutting off in extreme cold?
On high efficiency furnaces, frost or snow can block the intake or exhaust pipe, and a frozen condensate line can back water into the trap. Both trip the pressure switch. Older furnaces that run nonstop can also overheat and trip the high limit when the filter is dirty.
My emergency heat isn't working. What can I do to fix it?
Check the breakers for the heat strips, which are often separate from the outdoor unit breaker. If those are on and the strips still do not heat, a sequencer, relay or heating element has failed and needs a repair.
