What’s your furnace doing?

Pick the closest match. Each page walks through the likely causes, what you can safely check yourself, and what our technician will look at.

Why Pueblo is hard on furnaces

Pueblo averages 5,334 heating degree days a year (NOAA’s 1991–2020 normals), and the cold doesn’t arrive gently. Four local conditions are worth knowing about.

−20°F Fast, deep cold snaps

Feb 15, 2021 hit −20°F. Dec 22, 2022 hit −15°F. On Jan 21, 2025 Pueblo woke up to −19°F and reached 49°F that afternoon — a 68-degree swing in under a day.

≈4,700 ft Thin air

Above 2,000 feet, furnaces need their gas input adjusted for altitude, and some models need high-altitude parts. Pueblo West sits higher still, around 5,000 feet.

55+ yrs Older houses

The city says the average Pueblo home is more than 55 years old, and about half of single-family homes were built before 1980 — older ductwork, chimneys and, in some houses, boilers.

28.3 in Snow on the vents

That’s Pueblo’s normal seasonal snowfall. High-efficiency furnaces vent through plastic pipes on an outside wall, and a drift over them can shut the furnace down.

If your furnace has been acting up, get it looked at before the next arctic front instead of during it.

Check these before you call

These take a couple of minutes and sometimes get the heat back on. If you smell gas, skip all of this — get outside and call 911.

  1. Thermostat

    Set to Heat, set a few degrees above room temperature, with fresh batteries if it uses them.

  2. Furnace switch

    A switch that looks like a light switch, on or near the furnace, must be on.

  3. Breaker

    If the furnace breaker tripped, reset it once. If it trips again, leave it off and call — something in the furnace is probably causing it.

  4. Filter

    A clogged filter can make the furnace overheat and shut its burners off. Swap it if it’s dirty.

  5. Vent pipes outside

    After snow, check the white plastic pipes on the outside wall (high-efficiency furnaces). Clear snow or ice from the openings.

  6. Error light

    Look through the small window on the furnace door for a blinking light and count the flashes. Tell us the pattern when you call.

Still nothing? Furnace won’t turn on goes deeper, or just call — Call (719) 670-8043

What happens when you call

One number, answered 24/7. The full walkthrough is here.

  1. Tell us what it’s doing

    No heat, cold air, a noise — plus your ZIP code and the kind of system you have. A gas smell or CO alarm isn’t a repair call: we’ll tell you to get outside and call 911.

  2. We set the visit

    We schedule a technician as soon as one can get to you. Without heat in freezing weather? Say so.

  3. Diagnosis and a price first

    The technician finds what failed and explains the repair and its cost before doing it. The decision is yours.

  4. Repair and a full test

    After the fix, the furnace is run through a heating cycle to confirm it lights, heats and shuts off the way it should.

Inside Pueblo city limits, natural gas comes from Xcel Energy and electricity from Black Hills Energy. Pueblo West is split between two gas companies and two electric companies — here’s what that means for you.

Questions we hear

Do you work in Pueblo West?

Yes. Pueblo West (81007) is part of our regular service area, along with every Pueblo ZIP code from 81001 to 81012. Pueblo West has a few real differences — it sits higher than the city and it’s split between two gas and two electric utilities — so we wrote a page just for Pueblo West.

Can I call at night or on a weekend?

Yes. We answer 24/7. If you’re without heat, say so when you call — especially if a cold front is on the way or someone at home is elderly, very young or medically fragile — so we know how urgent the visit is.

What should I do if I smell gas?

Leave the house right away without flipping switches or using your phone inside. From outside, call 911 or Xcel Energy’s gas emergency line at 1-800-895-2999. If your gas bill comes from Colorado Natural Gas (part of Pueblo West), use the emergency number on that bill. Don’t call us first — a gas leak is an emergency for the gas company and the fire department.

Does Pueblo’s altitude matter for my furnace?

Yes. Pueblo sits around 4,700 feet and Pueblo West around 5,000. Furnace manuals commonly call for reducing the gas input above 2,000 feet — often 4% per 1,000 feet — and some models need high-altitude pressure switches or gas orifices starting anywhere from 4,000 to 5,500 feet, depending on the brand. Pueblo falls right in that band, so the setup has to follow your furnace’s own manual. More on our furnace replacement page.

How long does a furnace last?

Carrier puts a well-maintained gas furnace at about 15 to 20 years. Past 15, frequent repairs, rising gas bills or one big repair are good reasons to price a replacement before you pay for the fix. See repair or replace.

My furnace smells like burning the first time I turn it on. Is that normal?

A dusty, burning smell on the first cold night of the season is usually dust burning off and typically fades within a few hours. A burning-plastic or electrical smell is different: turn the furnace off and call us. A rotten-egg smell means gas — get outside and call 911. Details on our noises and smells page.

Do I need a permit to replace a furnace in Pueblo?

Yes, a replacement needs a mechanical permit. Since January 1, 2026, permits inside Pueblo city limits go through the Southern Colorado Building Department, which replaced the Pueblo Regional Building Department. Pueblo West and the rest of unincorporated Pueblo County now go through Pueblo County’s own building division. Colorado law also requires a working carbon monoxide alarm near the bedrooms when a permitted furnace replacement is done.
