You can take a few smart steps that will keep your heating, ventilation and air conditioning system running an extra long time.

Here  are some tips on ways to extend the life of your HVAC, delaying perhaps for years the need to buy an expensive new system:

First, change filters whenever they get dirty.

Customers don’t realize that dirty filters are an HVAC repairman’s best friend.

Dirty filters slow systems, make them work harder and eventually bring them to a halt. Customers can save themselves repair calls simply by cleaning or replacing filters when they get dirty. The few dollars you spend on filters will reduce repair calls and lessen the system’s workload.

Help your system breathe.

Check the outside unit to make sure that branches, grass clippings or animals haven’t worked their way inside. Indoors, make sure no furniture is blocking a vent.

Obstructions make the system labor more, shortening its lifespan and raising your utility bill.

Get a regular checkup.

Just as you change the oil and components in your car periodically to keep it running efficiently, you need a technician to check your HVAC system annually or semiannually.

These checks make sure all parts are in shape and ready for summer or winter. HVAC contractors often offer maintenance contracts that include price breaks and put you at the top of their call list if you have an emergency.
