The Basics of a Furnace Warranty
Posted On: February 17, 2025
A furnace warranty is an important aspect of purchasing a new heating system, as it protects homeowners from unexpected repair or replacement costs. Understanding the basics of a furnace warranty can help you maximize coverage and avoid issues down the line. Here’s what you need to know:
1. Types of Furnace Warranties
- Manufacturer’s Warranty – Covers defects in materials or workmanship. Typically lasts 5 to 10 years, with some premium models offering lifetime heat exchanger coverage.
- Labor Warranty – Provided by the installer or HVAC contractor, covering labor costs for repairs. Usually lasts 1 to 2 years.
- Extended Warranty – Offered by the manufacturer or third-party providers for additional coverage beyond standard terms. This may cover parts, labor, or both.
2. What a Furnace Warranty Covers
Most standard warranties cover:
- Heat Exchanger (often the longest coverage period)
- Blower Motor
- Burners
- Ignition System
- Electrical Components However, warranties generally do not cover maintenance, filters, or damages caused by improper installation or neglect.
3. How to Maintain Warranty Coverage
- Proper Installation – Ensure a licensed and certified HVAC professional installs the furnace.
- Regular Maintenance – Some warranties require annual servicing by a professional to remain valid.
- Timely Registration – Many manufacturers require product registration within a specific timeframe (e.g., 60–90 days) to receive full coverage.
- Use Approved Parts – Using non-manufacturer parts or unauthorized repairs may void the warranty.
4. Common Warranty Exclusions
- Damage due to lack of maintenance
- Improper installation or unauthorized repairs
- Normal wear and tear
- Environmental factors (e.g., power surges, flooding, or fire)
5. Transferring a Furnace Warranty
If you sell your home, some warranties are transferable to the new homeowner, but this may require a transfer fee or specific paperwork.
Final Thoughts
A furnace warranty can save you money on repairs and replacements, but understanding the terms and conditions is essential. Always read the warranty documents carefully, schedule regular maintenance, and keep all receipts and service records to ensure continued coverage.

We are very happy to recommend this company to everyone. Our furnace broke down on Sunday morning. We phoned them and before noon Grant the owner showed up. He worked on the furnace for about a hour not wanting to give up to fix the problem. The furnace was 17 years old. I was the one talking about replacing it. End result was the next day it was all done. On the Sunday Bob came over with heaters to warm up the house. We decided to replace the water heater at the same time. Thanks Grant for the excellent work. Thumbs up.

Right on time. Explained how to work the HRV in a different way so the house would not be so dry. Changed my whole house water filter for me as well. Friendly, helpful, caring service!

TwinTech is an excellent and honest company! I called them for a second opinion after being told by another company that I needed to replace my furnace. Turns out this was not the case at all! I did not need a new furnace. TwinTech did not push to make an unnecessary sale and saved me from a huge expense. Bob and Mitch were extremely professional and above all honest! I definitely recommend TwinTech!

Amazing experience with TwinTech Heating & Cooling! Their team was professional, knowledgeable, and efficient from start to finish. They installed my new furnace quickly and left everything spotless. The technicians took the time to explain everything and made sure I was comfortable with the system before they left. Great customer service and fair pricing. I highly recommend them for anyone needing HVAC services!

I returned from vacation to find my AC unit on the Fritz. After calling way too many places I connected with TwinTech. Ive used the company in the past for my furnace so I was happy when I recognized Greg at my front door. Hes great and the service is always top notch. Id highly recommend using twintech for honest, superior service in the Durham region. Thanks!

I called Twin Tech when my air conditioning stopped working. Greg came over to diagnose the issue - the same day. He was able to diagnose the issue and resolve it quite quickly. Although it was a quick fix, Greg was very thorough in explaining the issue and provided great advice. Not to mention, I felt very comfortable having Greg in my home - which I consider very important when hiring a service provider. Twin Tech will be my go-to from now on. Thank you!!
