Furnace Repair in
Greeley, CO

Lion diagnoses the real problem before
you pay to fix it.

Lion Home Service repairs furnaces across Greeley from our shop on West 16th Street, often the same day when our schedule has room. January nights here settle near 17°F, so a furnace that quits after dinner cools the house before morning.

Too many contractors price a new system before anyone pulls the burner cover, which turns one failed sensor into a replacement decision you never needed to make. Our technician finds the real fault first, then quotes one flat price, so your heat comes back on that first visit.

Call (970) 587-3498 anytime, then pick the window that fits your day. Our dispatcher phones you before the technician leaves.

2. Meet your technician

Booties go on at the door. Your technician walks you to the furnace, then explains each reading in plain English.

3. Approve one flat price

You see one flat price for the repair. Nothing moves until you say yes.

4. Get your heat back

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

Should I run the furnace while I wait for the appointment?

Maybe. Turn it off when you smell gas or hear a boom at startup. In that case, call us from outside the house. A furnace that blows cool air poses no danger, so leave the thermostat set while the system cycles until your technician arrives.

Get Your Questions Answered Before the Technician Arrives

How much does furnace repair cost in Greeley?

Your price depends on what’s actually wrong and which parts are involved. A flame sensor cleaning costs far less than a control board replacement. Lion quotes the number before any work starts, and Care Club members save on the visit.

Can one of your technicians come out today?

Often, yes. We hold same-day slots for furnace calls and fill them as they come in. Call early, and our dispatcher will tell you honestly what today looks like.

Is it safe to keep running my furnace if the pilot light looks yellow?

Not for long. A yellow pilot light can point to incomplete combustion, which is worth having checked quickly rather than waiting it out.

Should I repair my furnace or replace it?

It depends on the system’s age, the repair cost, and how it’s been running. Lion lays out both options honestly so you can decide what makes sense for your home and budget.

Why does my furnace struggle more during a hard freeze?

An aging or undersized system that manages fine most of the winter can fall behind the moment Greeley hits a hard freeze overnight. That’s usually when a small issue turns into a no-heat call.

Do you work on furnaces outside Greeley?

Yes. Lion services furnaces across Northern Colorado, including Loveland, Fort Collins, Windsor, and the surrounding rural communities.
