No heat, but the fan still runs.
The blower runs, yet nothing warm reaches the vents. That points to the ignition chain, meaning the igniter, the pressure switch, or the gas valve.

Why Furnaces Quit on Denver Nights
A Denver winter does not hold still. On a typical winter day, the low and the afternoon high sit about 26 degrees apart. Afternoons turn mild, and nights still freeze. So the furnace rests at lunch, then starts again and again after dark, through the long hours until morning. Each start runs the same chain, from the inducer and pressure switch to the igniter and flame sensor. Worn parts limp along. When one finally gives out, it is likely on a cold night, when the furnace runs hardest.
Havana Solutions repairs furnaces across the Denver metro, from a failed igniter to a dead control board. Every visit starts with a full diagnosis of that chain before anyone names a fix. Nobody guesses. You see what failed, with photos, and the price comes in writing before anything gets fixed. Then you decide.
26°F
The average daily swing between a Denver winter low and high, per NOAA climate normals.
33 days
In a typical Denver winter when the afternoon high reaches 50°F or warmer.
84 nights
Out of roughly 90 winter nights in Denver, the low reaches freezing or colder, on average.
5 parts
Igniter, pressure switch, limit switch, door switch, and capacitor included for plan members.
Signs Your Denver Furnace Needs Repair
Small faults grow. Watch for these. Spot one, and book the diagnosis before the next cold snap sends the furnace into a long night of starts.
Burners light, then shut off within seconds.
The control board closed the gas valve because the flame sensor never confirmed a flame. A dirty sensor is a common cause.
Nothing happens at all.
No hum, no fan, no click. Check the breaker and the thermostat batteries. If both are fine, a door switch, board fuse, or transformer may have failed.
A blinking light inside the panel.
Many furnaces flash a fault code through a small window in the door. Count the blinks and tell us when you call.
A bang when the burners light.
Gas that builds up before it lights can ignite all at once. Turn the furnace off and call. If you smell gas, leave the house and call 911 from outside.
Humming, squealing or grinding.
A hum with no fan can mean a failed capacitor. Squealing or grinding points to the blower motor or its bearings.
Is the furnace past saving? We will tell you so, and the replacement gets its own written quote, separate from any repair price. If a heat pump is on your mind, a cold-climate heat pump can take over the heating. Xcel Energy rebates help with the cost on qualifying systems. Already running a heat pump? We handle heat pump repair too. Boilers and radiators fall under our boiler and hydronic heating work, from cast-iron radiators to baseboard heat.
How Much Does Furnace Repair Cost in Denver?
- Callers ask about the fee first. It is $70. That one fee covers the trip and the full diagnosis, and it comes off the bill once you approve.
- After that, the part sets the price. An igniter and a control board are not priced the same, and the condition of the furnace matters too.
- Nothing gets fixed until you see that price in writing and say yes. Plan members pay no truck fee. If replacement makes more sense, it gets its own quote.
We Replace the Part That Failed, Nothing More
What Each Furnace Part Does
The job is to fix what broke. If the igniter failed, you pay for an igniter, and the rest of the furnace stays as it was. Other worn parts we spot along the way get a photo and a note. Replacing them is your call, now or later, and nothing changes on the bill without your yes.
| Part | What it does | On the maintenance plan |
|---|---|---|
| Inducer motor | Pulls exhaust out through the vent before the burners light | 10% off |
| Pressure switch | Confirms the vent is working before ignition starts | Included |
| Igniter | Heats up to light the gas | Included |
| Flame sensor | Proves there is a flame, or the gas shuts off | 10% off |
| Limit switch | Shuts the burners off if the furnace overheats | Included |
| Capacitor | Helps the blower motor start and run | Included |
| Door switch | Cuts power when the panel comes off | Included |
| Control board | Runs the startup sequence in order | 10% off |
We Look Past the First Fault
Why Denver Homeowners Call Us for Furnace Repair
You learn what broke and why.
We show you the failed part, explain its job in the startup chain, and say what likely wore it out. Next time, you spot it early.
We test past the obvious part.
Before naming any fix, the technician runs the furnace through its startup chain, even when the first fault looks obvious. A second worn part can hide behind the first one, and finding it now beats a second breakdown in January. It takes a little longer.
All major brands, whoever installed it.
Some homeowners hesitate to call a new company about a furnace that someone else installed. They should not. We work on all major brands, and the diagnosis follows the same steps on each one, old or new. Have the model number handy if you can.
From a Cold House to a Running Furnace
Tell us what the furnace is doing
A person picks up, not a phone menu. Describe the noise, the blinking light or the silence, and when it started.
We track down the fault
The technician runs the furnace through its startup chain and checks each part along the way. Photos catch what we find.
You decide
The repair price comes in writing. Nothing gets fixed until you say yes.
The heat comes back on
We replace the failed part and run the furnace until the house warms up. Anything else worth watching, you hear about before we leave.
