Warranty Information

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.

Click on the manufacturer below to view your more information about the warranty your manufacturer offers. 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.

    “Our technician Darryl was very thorough, honest and informative. He did a great job maintaining our unit and showed us before and after photos. He was on time and cleaned up any mess before he left. I would definitely recommend Sierra for all of your HVAC needs.”

  • Occasionally I run into a company that values its reputation and understands what "customer service" actually means. Sierra is that rare breed.

    “Occasionally I run into a company that values its reputation and understands what "customer service" actually means. Sierra is that rare breed. I'm trying to think of something that didn't go as promised but I can't. They responded to my emergency immediately, diagnosed the problem, explained what had to be done, then did it. Jeremy, who installed my new water heater, explained everything in terms I could understand, was thorough, courteous, laid plastic on the marble floors to make sure there weren't any scratches, and was an absolute gentleman. The price was fair and I couldn't be more satisfied with the entire process. These people obviously have pride in what they do. I would recommend them without hesitation.”

    “We are new customers to Sierra Air. Jeremy was scheduled to arrive between 2 and 6. He showed up before noon and did a very thorough inspection of our two air conditioner units. We were so impressed, we purchased the service agreement. We look forward to working with Sierra Air in the future.”
