Manufacturer's Warranties

May 07, 2012


When you pay for a new heating and cooling system, the last thing you want to happen is to find out that it’s not covered under the warranty due to something that you did, or did not do. Many of us don’t take the time to read the owner’s manuals or warranty cards, even though we know we should.  While you’re trying to remember where you put your manual, here are some quick tips to help you stay within your manufacturer’s warranty. Of course, you need to read the warranty that accompanies your system. These tips are only to be used as general guidelines and aren’t meant to be comprehensive for every system.

  • One major factor that voids many warranties is lack of service.  Your furnace needs to be cleaned and tuned-up every fall.  Your air conditioner needs the same treatment every spring.  If you don’t have documentation that your system has been maintained according to the manufacturer’s requirements, they may not cover any necessary repairs.  Other advantages to annual service include keeping your system running efficiently, avoiding surprise breakdowns and the accompanying emergency repair bills, and extending the life of your system. 
  • Never order any parts from the internet.  Order them and have the installed through a licensed dealer.  Saving a few dollars on a part voids the entire warranty.
  • Proof of purchase may be required if your system needs any maintenance done under the warranty; keep it near the owner’s manual and warranty information so you can’t misplace it.
  • New systems must be installed by a licensed HVAC contractor.  Any system or component not installed by licensed contractor will void the warranty for the entire system.  It’s worth it to work with reputable companies when the investment numbers in the thousands of dollars.
  • Also, if any heating and cooling equipment is moved from its original location in your home, the warranty will be voided.
  • Never alter your system or use it for unintended purposes.

Some manufacturers offer an extended warranty for your system if the new system is registered with the company within a certain period after installation. At least one major manufacturer offers a 10-year parts limited warranty instead of a 5-year warranty, if the system is registered within 90 days.  It’s definitely worth a few minutes of your time to register in this case. Heating and cooling systems are a major investment.  Make sure yours is covered; a little of your time will save you a lot of money.
