How to Extend the Life of Your HVAC System

Your HVAC system is a major investment. In Arizona’s hot climate, keeping it running efficiently for as long as possible means saving money and avoiding untimely breakdowns. Here are some key steps homeowners can take to extend the life of their HVAC system:

1. Change air filters regularly

Clean filters protect internal components and ensure proper airflow. You should change them every 1 to 3 months depending on system use, pets, and dust. Signs your filter needs replacing include visible dirt, excess dust throughout your home, reduced airflow, increased utility bills, or more allergy symptoms.

2. Rinse your condenser coils

Outdoor units collect dust and debris, especially in the desert. To clean your coils, disconnect the unit at the plug or breaker. Remove debris around or inside the unit, and use a vacuum if needed. Lightly spray the coils with water or coil cleaner. Avoid high water pressure. If you’re unsure, a professional can handle this task.

3. Schedule professional maintenance

Once or twice a year, schedule maintenance with a qualified HVAC technician. Spring and fall tune-ups prepare your system for the new season and catch problems early. A maintenance visit typically includes a detailed checklist. With Mountain Peak Air’s Peak Plans, customers receive an annual chemical coil cleaning as part of their service plan.

4. Use a programmable thermostat

Avoid overworking your HVAC system by setting realistic schedules. Reduce run times when you’re asleep or away. This lowers energy bills and helps extend the life of your system.

5. Improve home insulation

Poor insulation forces your system to work harder. Make sure attics, walls, windows, and doors are well insulated. Weather stripping or caulking can help seal leaks and retain cooled or heated air.

6. Inspect and repair ductwork

Leaky ducts waste energy and strain your system. Watch for uneven temperatures, increased dust, or higher utility bills. Have your ducts professionally cleaned, sealed, or repaired if needed.

7. Use the “auto” setting

Leaving your fan on “on” may not be necessary to keep your home comfortable. Using the “auto” setting reduces fan use and wear on the blower motor. It also helps maintain more consistent humidity and temperature levels.

8. Keep vents and registers clear

Blocked airflow can reduce efficiency and strain the system. Keep furniture, rugs, and curtains away from vents. Vacuum dust and debris from registers regularly.

9. Upgrade when it’s time

An aging, inefficient system can drive up repair and energy costs. Newer systems offer better longevity and higher SEER ratings. If repairs are frequent and costly, it may be time for an upgrade.

Keeping up with regular care and maintenance makes all the difference. Simple tasks go a long way toward improving comfort, reducing energy costs, and extending the life of your HVAC system. Contact Mountain Peak Air to schedule your next tune-up or to get a quote for a new system.
