Register your warranty online

In order for your warranty to be valid and effective, you must go online and register your new Home Comfort System equipment with the manufacturer. The timeframe to register your equipment, details, and length of your warranty may differ depending on your manufacturer.

Each manufacturer has varying requirements to register your system for the additional 5 year parts warranty. Starting in 2016, some manufacturers require online registration of equipment within 90 days, while others require you to register within 60 days.

We have included some general information you will need to gather from your equipment in order to register your warranty. If your equipment's information is inaccessible to you, please feel free to call us and we can help you look up the information you need about your equipment.

*Extended 5 year warranty on parts applies to parts warranty only. Not all manufacturers may offer this extended parts warranty. You must check with your manufacturer.

  • I appreciate the care they take in your home

    “I am impressed with Sierra Air. I have received service twice from their company. I appreciate the care they take in your home--wearing shoe covers and placing a drop cloth on the flooring before setting their ladder down. (And they bring their own ladder! I've actually had an HVAC technician ask to borrow one :) Tim D was extremely polite and professional. He was patient in taking the time to discover the problem I had called about. 'Cause wouldn't you know, the sounds I had been hearing weren't happening when he got there. He really took the time to figure out what might be causing the concern I had. I'm glad he didn't give up because he finally got to hear what I had been talking about. He had assured me that the problem we were having would be resolved that day. He also addressed another smaller concern. And he gave me tips on setting my thermostats and the types of filters I should use. Give Tim a bonus! :)”
