A Complete Guide to Furnace Warranties

When purchasing a new furnace, the warranty is a critical factor to consider. It not only provides peace of mind but also protects your investment from unexpected repair costs. This guide will break down everything you need to know about furnace warranties, helping you make an informed decision.
Furnace warranties typically fall into three main categories:
The manufacturer’s warranty covers defects in materials and workmanship. These warranties generally last between 5 to 10 years and vary by brand and model. Key components, such as the heat exchanger, may have extended coverage—sometimes up to 20 years or a lifetime.
Labor warranties cover the cost of labor required to repair or replace parts under the manufacturer’s warranty. Often offered by HVAC contractors, these warranties typically last 1 to 5 years, although extended labor warranties may be available for an additional cost.
Extended warranties are optional plans that extend coverage beyond the manufacturer’s warranty. They often include both parts and labor and can last up to 10 years or more. Be sure to read the fine print, as these plans may require additional fees and regular maintenance.
When evaluating furnace warranties, consider the following:
Ensure you understand how long the warranty lasts for various components and services. Some parts, like the heat exchanger, may have longer coverage than others.
A transferable warranty can increase the resale value of your home, as it allows the new owner to benefit from the remaining coverage.
Most warranties exclude damage caused by improper installation, lack of maintenance, or misuse. Familiarize yourself with these exclusions to avoid invalidating your warranty.
Many manufacturers require you to register your furnace within a specified period (typically 60 to 90 days) to activate the full warranty coverage. Failing to register may result in reduced coverage.
Hire a Qualified Installer: Many warranties require professional installation by a licensed HVAC contractor. DIY installation can void your warranty.
Schedule Regular Maintenance: Keep up with annual furnace tune-ups and filter replacements. Retain service records as proof of maintenance.
Use Authorized Parts: Repairs and replacements should use parts approved by the manufacturer to avoid voiding the warranty.
Understand the Claim Process: Familiarize yourself with the steps for filing a warranty claim, including required documentation and timelines.
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!
Very pleased with the professional service that TwinTech Heating and Cooling provided in replacing my furnace. I got several quotes from different service providers. Their price was excellent and they explained the features very well. We are very glad we went with TwinTech and highly recommend their services.
We were new homeowners in need of a second opinion. TwinTech Heating & Cooling were Amazing and professional. Very knowledgeable and great service all around. Recommend to anyone looking for honest and reliable services. Treated with respect and care. Thank you Greg, Mitch and Bob!
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!
Great experience all around. Bob was sharp and easy to talk to, and Greg handled the installation perfectly. Would hire them again in a heartbeat.
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!!
Just hired TwinTech Heating & Cooling to do an A/C Unit removal & reinstall to allow for landscaping access on the side of my house, and they were wonderful!
Bob, Greg & Mitch make a great team! Quick appointment times, super knowledgeable, expert troubleshooting capabilities & very customer service oriented.
I would highly recommend them for all of your HVAC needs! Great job guys!!
