Furnace Repair in
Fort Collins, CO

Lion Home Service repairs furnaces across Fort Collins, often the same day when our schedule has room. At 5,003 feet, with January lows averaging near 14°F, a dead furnace cools a house within hours. Too many contractors quote a replacement before anyone opens the burner compartment. Our technician finds the real fault first, then prices the repair before any work starts, so your heat comes back on that same visit.

What Matters When Your Heat Quits
Lion Home Service
Other Contractors
Reaching a human at 9 p.m.

A local person answers, then books your morning slot on that call.

An answering service takes a message that a dispatcher returns the next business day.

Diagnosis before a sales pitch

Our technician meters the failing part and shows you the reading on the screen.

A glance at the data plate becomes a replacement quote for a furnace that needed one sensor.

Knowing the price first

You approve a flat number before the first screw comes out. The invoice matches it.

Hourly labor plus an unquoted parts markup arrives as a total after the work ends.

Finishing on the first visit

Our trucks stock the ignitors and control boards that fail most often on Fort Collins furnaces.

A parts run turns your repair into a second appointment two days out.

Setup for 5,003 feet

We derate gas pressure for our altitude so your burners run clean through winter.

Factory sea-level settings never change, and the furnace runs rich all season.

Your floors afterward

Booties go on at your door, and the shop vacuum comes out before we leave.

Boot prints track from the front door to the furnace closet.

The rest of your house

The crew that fixed your furnace also clears your sewer line in March.

A furnace-only shop hands you a referral when your water heater fails.

Life after a bad review

We call you, then fix what went wrong.

A copy-paste reply posts under your review, and nobody calls.

Follow Your Repair From First Call to Warm House

Four steps take you from a cold house to a working furnace.

Book Your Visit

Call (970) 510-0522 at any hour, or book online in about a minute. Our dispatcher locks in your window, then texts you before the technician leaves for your address.

Meet Your Technician

Booties go on at the door. Your technician walks to the furnace with you, then explains every reading in plain English while he tests the system.

Approve One Flat Price

You see a single number for the fix. Nothing moves until you say yes, so the invoice never surprises you.

Get Your Heat Back

Most jobs finish that visit because the common parts ride on the truck. We check back afterward to confirm your house holds its temperature overnight.

Get Your Questions Answered Before You Book

How long does a furnace repair take?

Most Fort Collins repairs run 60 to 90 minutes once our technician isolates the fault. Heat exchanger imaging adds roughly half an hour. If we have to order a part, it may require a second appointment, usually two business days out.

How long do you stand behind the repair?

Lion Care Club members carry a 5-year warranty on every repair we recommend. Membership starts at $199 a year and takes 15% off the ticket, with no $29 dispatch fee on the visit.

When does replacement beat another repair?

Watch the math once your furnace passes 15 years. A repair quote above one-third of a new system’s price rarely pays off on a unit that old, and our technician will show you both numbers so the choice stays yours.

Will my manufacturer warranty cover the parts?

Often, yes. Most furnace makers cover parts for 10 years when the original owner registered the unit. Our technician pulls your serial number on site, then files the claim so you pay labor only.

What can I check before I call?

Start with your thermostat batteries, then confirm no one has flipped the switch on the furnace wall. A filter loaded with late-summer smoke chokes airflow enough to trip the limit switch. If your heat stays off, call us.

Book Your Fort Collins Furnace Repair

Call (970) 510-0522 whenever your furnace quits, day or night, and a local person picks up. Booking online takes about a minute, and our dispatcher confirms your 7 a.m. to 7 p.m. window.
