Yes, and there are two separate layers you should understand: the manufacturer’s warranty on the equipment, and our workmanship warranty on the installation. They cover different things, and the gap between them is where homeowners get caught.

The Manufacturer’s Warranty

Equipment warranties cover the furnace itself — heat exchanger, control board, blower motor, inducer, igniter. Terms vary by manufacturer and model, with heat exchangers typically carrying the longest coverage and other components a shorter term.

Registration matters. Many manufacturers offer an extended term if the equipment is registered within a window after installation, and default to a much shorter base warranty if it is not. We handle registration as part of the job rather than leaving it as homework you forget.

The Gap Nobody Explains

Here is the part that surprises people: almost no manufacturer warranty covers labor.

If a heat exchanger fails in year eight of a twenty-year warranty, the manufacturer sends a replacement part. Someone still has to disconnect the gas, pull the furnace, disassemble it, install the exchanger, reassemble, and re-commission the system. That labor bill is yours unless the installing company covers it.

On a major component, labor can approach the cost of a significant repair on its own. This is why a warranty claim can still leave you with a real invoice, and why the installing contractor’s own coverage matters as much as the manufacturer’s.

Our Workmanship Warranty

Our coverage applies to what we did — the gas connection, venting, condensate routing on condensing units, electrical, ductwork connections, and commissioning.

If something we installed was installed incorrectly, we come back and correct it at no charge. That is the practical meaning of our Home Comfort Guarantee: the outcome is our responsibility, not just the parts.

What Actually Voids Furnace Warranties

Manufacturers deny more claims than homeowners expect, and the reasons are consistent enough to be worth listing.

No documented maintenance. Most warranties require annual professional service. No records, no claim. This is the most common denial by a wide margin.

Restricted airflow. A furnace that overheated because nobody changed the air filter has a heat exchanger that failed from neglect, and manufacturers know how to identify that.

Improper installation. Wrong venting, incorrect gas pressure, undersized ductwork, or a unit oversized for the home.

Unlicensed installation. Many warranties are void outright if a licensed contractor did not perform the work.

We handle the installation side as standard practice and document the job, which is what you need if you ever file.

Keeping Coverage Alive

The single most effective thing you can do is maintain the system and keep the records.

Annual furnace maintenance produces documentation and catches the airflow and combustion problems that cause warranty-voiding damage in the first place. Members of our Care Club maintenance plan get it on schedule with records kept, which removes the remembering.

Changing your filter is the other half, and it is entirely on you between visits.

What to Ask Any Contractor

Whether or not you use us, these questions are worth asking before signing.

How long is the workmanship warranty, and what specifically does it cover? Is labor included on manufacturer warranty claims, and for how long? Will you register the equipment? What maintenance is required to keep coverage valid? Is the price inclusive of permits and any venting corrections?

A bid that is dramatically lower than others is usually lower because something was excluded, and warranty coverage is a common omission.

On a Replacement Decision

If you are weighing repair against replacement, warranty status is part of the calculation. A failed component still under coverage changes the math considerably compared to one that is not.

We check warranty status before quoting, and we will tell you if a repair you were about to pay for should be covered.
