You want to make sure you read up on your HVAC systems warranty if you can't recall the specifics regarding it. Especially before you turn it on for the start of the warmer season. You don't want to assume that all warranties are alike, as they can each include different clauses and some of those clauses can really mess you up if you don't know about them and do something you shouldn't to your system. This article will help to give you the basics of most warranties, so you will understand why it's so important to pay close attention to yours.
You shouldn't open anything sealed on your system – While regular maintenance of your HVAC system will generally call for things like cleaning the air filter and dusting the registers, it normally never calls for any part of the system to be opened or tampered with. When you unscrew a screw, the screwdriver will chip off some of the paint from the screw. This can be a giveaway to someone else that the unit has been opened before, and this can sometimes be all it takes for the warranty to be voided, leaving you financially responsible for all future repair expenses.
You may want to start with a call to the number on the warranty paperwork – When you have issues with your HVAC system, you want to check the warranty and see if you are supposed to report the issue to them first and then get approval to call out an HVAC technician. They may even be able to direct you to a local repair person they want you to have come out to take care of the problem.
Make sure everyone who touches the system is licensed – if it is up to you to find service repair technicians to repair your HVAC system, then you will want to make sure the person you have taking care of it is licensed. Otherwise, having them fix the unit is no different than you fixing it yourself in the eyes of the warranty.
Some parts are under warranty longer – You'll find that there are some parts of your system that may be covered under the warranty longer than others. This generally has to do with how long certain parts can go before they are in need of repairing. For example, parts known to go out the soonest won't be covered as long as parts that tend to last for a very long time.
