Repair or Replace?

Signs You Need a New Furnace

15–20+ Years Old

Furnaces this age lose efficiency fast and become harder to source parts for.

Cracked Heat Exchanger

A serious safety issue that can leak carbon monoxide — grounds for immediate replacement, not repair.

Rising Gas Bills

An aging furnace often burns more gas to produce the same amount of heat.

Uneven Heating

Some rooms too hot, others too cold, often a sizing or ductwork mismatch.

Frequent Repairs

If you're calling every season, replacement is usually the better investment.

Yellow Pilot Flame

A yellow (not blue) pilot flame is a warning sign of incomplete combustion — have it checked immediately.

FAQ

Common Questions

Can’t find your answer? Contact us or call 12 34 5678.

How is my new furnace sized?

We perform a real in-home load calculation rather than matching your old unit’s size, which is often wrong to begin with.

What's the difference between single-stage, two-stage, and modulating furnaces?

Single-stage furnaces run at full output only. Two-stage and modulating furnaces adjust output to match demand, which typically means more even heat and lower gas bills — we’ll walk you through which fits your home and budget.

Do I need a permit for furnace replacement?

Yes, in nearly every case. We handle the permit and inspection as a standard part of every installation — see our permit requirements guide for detail.

How long does installation take?

Most furnace replacements are completed in a single day.

What warranty comes with a new furnace?

You get both the manufacturer’s equipment warranty and our written labor warranty.
