HVAC Systems
Your heating, ventilation, and air conditioning system is one of the most expensive components in your home. Proper maintenance helps it last longer and run more efficiently.
Cost of neglectEarly failure can mean replacing the whole system
Maintenance tasks
- Replace air filtersEvery 90 days (monthly if you have pets)Dirty filters force your system to work harder, increasing energy costs and causing premature wear.
- Schedule professional tune-upTwice yearly (spring and fall)Technicians catch refrigerant leaks, electrical issues, and efficiency problems before they become expensive repairs.
- Clean vents and registersMonthlyDust buildup restricts airflow and can trigger allergies.
- Clear area around outdoor unitAs neededDebris blocks airflow and reduces cooling efficiency.
- Check thermostat batteriesAnnuallyDead batteries can cause the system to stop working at the worst time.
Pro tips
- Keep trees and shrubs at least 2 feet from outdoor units
- Consider a programmable thermostat to lower energy bills
- Listen for unusual sounds - they often indicate problems
- Change filters more often during peak usage seasons
Plumbing
Water damage is one of the most common and expensive home insurance claims. Regular plumbing maintenance prevents catastrophic leaks and the repairs and mold remediation that follow.
Cost of neglectWater damage or freezing claims averaged $15,400 (Insurance Information Institute, 2019 to 2023)
Maintenance tasks
- Check for leaks under sinksMonthlySmall leaks become big problems. Early detection saves thousands.
- Flush water heaterAnnuallySediment buildup reduces efficiency and shortens tank life.
