Signs You Need Furnace Repair in Arvada
Furnaces rarely go from fine to dead overnight. They usually drop a few hints first, and catching those early tends to keep the repair small.
- It won't start, or it starts and shuts off before the house warms up
- The vents blow cool air, or some rooms never reach the temperature you set
- You hear banging, squealing, grinding, or rattling while it runs
- It turns on and off every few minutes, which techs call short cycling
- The burner flame looks yellow or flickery instead of a steady blue
- You notice burning, electrical, or rotten-egg smells
A heating bill that keeps creeping up while your thermostat habits stay the same is a quieter clue. If you ever smell gas, get everyone outside and call Xcel Energy before you call us.
Call (720) 538-8755Furnace Problems We See Most in Arvada
Living above 5,000 feet on the Front Range is great for the views and a little rough on furnaces. These are the furnace repair issues that come up again and again:
- Dry, dusty air clogs filters fast, which can make the furnace overheat and shut itself down
- Big temperature swings, like 60 degrees one afternoon and single digits the next morning, add on-off cycles that wear out igniters and inducer motors
- Snow and ice can block the vent pipes on high-efficiency furnaces and trigger a lockout
- Furnaces that were never adjusted for our elevation can burn dirty and leave soot on the burners
- Wildfire smoke in late summer can load up filters before heating season even starts
What to Expect When You Call Us for Furnace Repair in Arvada
We'll start by asking what you've noticed. Small details, like "it clicks three times and gives up," can point us straight to the problem. Then your Arvada furnace repair technician works through the system:
- Thermostat settings, wiring, and batteries
- Error codes on the furnace control board
- The igniter, flame sensor, and burners
- Blower motor amp draw and the capacitor
- Limit switches, the pressure switch, and other safety controls
- The heat exchanger and venting, checked for cracks, rust, or blockages
Before we fix anything, we'll explain what went wrong in plain English and give you the price in writing. If the part is on the truck, we'll take care of it during the same visit. If we need to order it, we'll tell you when it should arrive and make sure your home is safe in the meantime.

A Few Things to Check Before You Call
Some no-heat calls come down to something you can fix yourself in a couple of minutes. Work through these in order:
- Make sure the thermostat is set to Heat and a few degrees above room temperature, then put in fresh batteries.
- Check your breaker panel for a tripped furnace breaker. Then make sure the furnace's power switch, which looks like a light switch near the unit, is on.
- Pull out the air filter. If it's gray or packed with dust, replace it.
- Make sure the furnace door panel is snapped firmly in place, since a loose panel trips a safety switch that keeps the system off.
- Open your supply vents and move any furniture or rugs off the return grilles.
- If you have a high-efficiency furnace, clear snow or ice away from the white PVC pipes outside.
If the heat still won't come on, or you smell gas or something burning, stop there and give our Arvada furnace repair pros a call.

Repair or Replace: How to Decide
A furnace repair in Arvada, CO usually makes sense when your furnace is younger than about 15 years, the problem is a single part, and it's been dependable until now. Replacement starts to make more sense once the furnace passes 15 years, breaks down more than once in a season, or needs a repair that costs more than half the price of a new one. A cracked heat exchanger on an older furnace usually settles the question.
We'll give you the numbers for both and let you decide. If you're leaning toward something new, our furnace installation and replacement page walks through your options. And if another company has already told you your furnace is done, we'll give you a free second opinion before you spend a dime.

Arvada Furnace Repair FAQs
Why is my furnace blowing cold air?
Check the thermostat first. If the fan is set to On instead of Auto, the blower runs even when the burners are off. If that setting looks right, a clogged filter can make the furnace overheat and shut off the burners while the fan keeps going. A failed igniter, a dirty flame sensor, or a gas valve problem can cause the same thing. If a fresh filter and a thermostat check don't solve it, we'll come diagnose it.
What should I do if my furnace won't turn on at all?
Make sure the thermostat is on Heat and set above room temperature, and swap in new batteries. Then check your breaker panel and the power switch near the furnace, and make sure the front panel is firmly in place. If it still won't start, the cause is usually an electrical part, the control board, or a safety lockout, and those need a technician.
Why does my furnace bang or squeal when it starts?
A loud bang at startup often means gas is building up for a moment before it lights, usually because of dirty burners or a weak igniter. That one is worth calling about soon. Squealing usually points to a worn blower motor bearing or belt, and rattling can mean a loose panel or a failing inducer motor. Tell your technician exactly what you hear and when, since it helps narrow things down quickly.
Is a burning smell from my furnace normal?
A light dusty smell during the first hour or so of the heating season is normal, since that's dust burning off the heat exchanger. A smell that sticks around, smells electrical, or comes with smoke is a different story, so turn the furnace off and call us. If it smells like rotten eggs, that could be a gas leak. Leave the house and call Xcel Energy first.
Can you help if my furnace stops working at night or on the weekend?
Yes. Our phones are answered live around the clock, so you'll always reach a real person who can get you scheduled as quickly as possible. Home Comfort Club members never pay overtime for after-hours service.
How long does a furnace repair usually take?
Many common repairs, like replacing an igniter, flame sensor, or capacitor, can be finished during the same visit once we know what's wrong. Bigger jobs, like a blower motor or control board, take longer and sometimes need a part ordered. Your technician will give you a realistic timeline before getting started.
How long does a furnace last in Colorado’s climate?
Most furnaces last 15–20 years, but cold Front Range winters can cause extra wear. Annual maintenance and timely repairs from Mighty Pine can help your system reach or exceed its full lifespan.
Why It Pays to Fix Furnace Problems Early
A furnace that's struggling in November usually struggles more by January. When one part slips, the rest of the system has to work harder to make up for it. A dirty flame sensor or an overheating blower motor can wear down other components until a simple fix turns into a much furnace repair bigger bill.
Safety matters too. A furnace that isn't burning or venting properly can leak carbon monoxide into your home. A furnace that quits during a cold snap can also leave your pipes at risk of freezing. Calling at the first sign of trouble usually means a smaller repair, a quicker appointment, and a warm house sooner.
What Furnace Repair Costs in Arvada
The price depends on what broke. Cleaning or replacing a flame sensor or igniter is on the lighter end, while blower motors, inducer motors, gas valves, and control boards cost more. Our diagnostic visit is $119, and if you have us do the repair, we waive that fee completely.
Home Comfort Club members pay no dispatch fee, never pay overtime, and get 10% off repairs. For bigger repairs, financing through Wells Fargo can help spread out the cost, subject to credit approval.
