How to void your HVAC warranty
New air conditioning and heating systems typically come with a manufacturer’s warranty that homeowners believe will protect their investment for years to come. However, there are things that a homeowner can do, or not do, that could void their warranty.
System Registration
Registering your system with the manufacturer after installation is essential. If you do not register your HVAC warranty with the manufacturer within the specified timeframe (typically 6 to 12 months), your system may not be covered.
The DIYer
When one component of an HVAC system stops working, many homeowners order a replacement part and fix it themselves. Unfortunately, though, a DIY repair job could void the system’s warranty. Most HVAC manufacturers require approval for all repairs, which a licensed HVAC contractor must then perform.
Annual Maintenance
Some people think that an air conditioning and heating system is self-sustaining and only needs maintenance when it begins to fail. Unfortunately, from a warranty standpoint, this is not good practice. Annual maintenance or service check-up from a licensed HVAC contractor is sometimes necessary to keep a warranty valid.
Improper Installation
If your heating and air conditioning system was improperly installed or installed by a non-licensed contractor, your warranty will probably not be honored. A reputable HVAC contractor will always provide a city permit for all installations. A permit will ensure that your city or county inspector will certify the work after installation is complete. Only a licensed contractor can pull an HVAC city installation permit.
Check with your manufacturer
In any case, read the warranty documentation that accompanied your system or contact the manufacturer for details of proper maintenance procedures.
