A standard HVAC system should remain operational for 12 to 18 years. Over the course of its lifetime, though, it will require periodic maintenance. Occasional repairs will also be necessary because its various components will wear down at different rates. Thankfully, there are ways you can extend the life of the system as a whole and its individual components. 

3 Tips for Prolonging the Life of Your HVAC System 

1. Tune It Twice a Year

Your air conditioner will be pushed to its limits during the warmer months, while your heater will be under a considerable amount of stress all winter long. As such, schedule a tuneup every spring and fall. The spring tuneup will ensure your AC operates at optimal capacity during the summer, while the fall tuneup will prepare your heater for the colder months.

The technician will inspect the entire system, lubricate any critical components in need of oil, clean the condenser, flush the drain tube, replace the filters, check the refrigerant levels, and address any minor issues before they turn into major problems. 

2. Switch the Fan to Auto

Check the fan setting on each thermostat. If any are turned to On, switch them to Auto. When the system is set to On, the fan will run continuously, even after the home has reached the desired temperature. If the fan is set to Auto, it will only run when air must circulate throughout the home to adjust the temperature. In other words, setting the fan to Auto will reduce wear and tear on the fan motor, thereby extending the life of the entire unit. It will also prevent the filters from clogging up too quickly.

If someone in your home has allergies or respiratory issues, though, the improved air quality that will result from keeping the fans on all the time may outweigh the strain it puts on your HVAC system. 

3. Give It a Break 

In extreme climates, it may be necessary to run the HVAC system year-round. In a place like Wisconsin, though, there may be a few weeks during the spring and another few weeks during the fall when you don't need heating or cooling. Turning the system off will give its mechanical components a break, thereby prolonging the need to make essential repairs.

Also, adjust the temperature before leaving to prevent the system from working harder than it needs to. Before traveling during the winter months, for example, set the temperature to 55 degrees or so. This will keep the pipes from freezing without straining the system while you're gone.
