Your new HVAC system should last between 15 and 25 years, but you can extend that time to its maximum capacity by maintaining its efficiency and reducing the workload on the mechanical components. Steps like changing the air filter, shading the condenser and scheduling regular tune ups will ensure that your HVAC system runs efficiently for many years to come.

Take Care of Your Condenser

Your air conditioner condenser works at the hottest times of year in the sweltering heat. The hotter it gets, the more difficult your condenser's job becomes. You can take care of your air conditioner condenser keeping it cool. Here's how:

• Shade the condenser. Strategically place trees, a large bush or a fence so that the condenser falls into shade.
• Keep weeds and debris away from the unit. Weeds, plants and other organic materials can clog the interior parts of the condenser, making it harder for your condenser to release heat and impacting its ability to effectively cool your house.
• Clean the coils on an annual basis. Cleaning the inside of the condenser improves air flow inside the unit, helping the parts stay cool.

Change the Air Filter

The air filter for your HVAC system fits in the space between the return air duct and the blower. The air filter cleans all the air that flows through your HVAC system, regardless of whether or not you're running the air conditioner or the furnace. The air filter needs to be replaced after every 3 months of use. This clock stops during seasons when you use the HVAC system little or not at all—like in the late spring and early fall. Keep track of how often you're using the HVAC system and change the air filter accordingly.

Schedule Annual Maintenance on the HVAC System

During annual checkups, HVAC repair technician will check the wiring and mechanical parts of the air conditioner and furnace. He or she will test the thermostat, check the pilot light for ignition, inspect the ducts, check refrigerant levels in the air conditioner and more. During this time, he or she might make recommendations for repair, like adding more refrigerant or sealing the ducts. Following your contractor's recommendations will help you maintain maximum efficiency on your HVAC system.

Get An Energy Audit

One of the best ways that you can reduce your HVAC system's workload is to improve your home's energy efficiency. Now that your home has a new HVAC installation, it's time to get an energy audit. Your energy auditor will identify the air leaks in your home that could be causing your HVAC system to run longer and harder than necessary. Here are a few ways that your home's energy efficiency may be improved:

• Bring old insulation up to code.
• Install new windows.
• Weather strip doors and windows.

Making these basic home improvements will ensure that your HVAC system runs only as long as necessary, and no more.
