Manufacturer warranties only cover parts, and this is only honored if a licensed HVAC contractor declares that manufacturer defect is the cause of the problem.

Parts warranties only cover large system components, not air filters, fan belts, electrical wiring or lubrication. You are expected to maintain these parts with the help of a qualified HVAC contractor.

You never see combined parts and labor warranties from manufacturers because they can’t control how the equipment is installed and maintained.

You can purchase extended parts and labor warranties from the contractor that installs your system. When combined with the original manufacturer warranty, you’ll enjoy the greatest long-term protection and savings if something goes wrong with the system.

Why are Tune-ups important?

You may wonder why Tune-ups are necessary if you have extended HVAC warranties to draw from. The truth is most warranties only remain valid if your system is serviced by a certified HVAC contractor, warranties and tune-ups go hand in hand.

Scheduled tune-ups help you avoid the hassle associated with unexpected breakdowns. They also pay for themselves by catching problems early, thus helping to avoid unnecessary repairs, and keeping efficiency high so your energy bills remain low.

What can void HVAC warranties?

Whether you pay for an extended part and labor warranty from your contractor or you stick with the basic limited manufacturer’s warranty, be careful that you don’t make the wrong move and accidentally void it. When you sign up for a warranty, read it carefully to make sure you adhere to the terms required by the manufacturer for that specific guarantee. In the meantime, here are five things that will almost certainly void HVAC warranties.

Failing to go through the registration process : Many manufacturers require that you register the warranty before it takes effect.

Getting replacement parts from another company: The company that manufactured HVAC equipment can’t risk guaranteeing another company’s products. When it comes time to repair your system with replacement parts, make sure you opt for parts made by the same company. It may be cheaper initially to choose an off-brand part, but it's not worth it if this action voids your warranty.

Installing the equipment improperly: A DIY or uncertified installation leads to poor equipment operation, comfort problems, and high energy bills. It may also void your HVAC warranties. That’s why you should only rely on expert installation from an experienced HVAC contractor.

Neglecting tune-ups: Here’s where tune-ups affect HVAC warranties, many of which you must have your equipment tuned up once a year to keep the warranty valid. Manufacturers can’t very well guarantee the performance of neglected equipment. After all, no matter how high-end your heating and cooling system is, it’s a machine and requires maintenance and periodic repairs to remain in good working condition for years to come.

Not keeping proper records: If you ever claim coverage from your warranty, the manufacturer will undoubtedly ask for proof of installation and maintenance from a credible contractor. Keep the receipts from these visits so you can show the manufacturer you only hired trusted professionals to tune-up or repair the equipment.

Did you know…Poorly maintained or dirty units typically work 20 percent harder and use more energy. The marginal costs of regular servicing are made back as you save money on your monthly bills.
