10 Essential HVAC Maintenance Tasks Every Homeowner Should Know
1. Replace or Clean Air Filters Regularly
How often should you change your filter? The general recommendation is every 1-3 months. However, this frequency depends on several factors:
- Pets: Homes with furry friends usually require more frequent changes (monthly).
- Allergies/Asthma: If anyone in the household suffers from respiratory issues, monthly changes are advisable.
- System Usage: During peak heating and cooling seasons when the system runs constantly, check the filter monthly.
- Filter Type: Basic fiberglass filters may need monthly replacement, while higher-efficiency pleated filters (like those with higher MERV ratings) might last up to three months. According to the EPA, filters with MERV ratings between 7 and 13 are effective at removing smaller, health-concerning particles. Always check the manufacturer’s recommendation and inspect the filter visually. If it looks dirty, change it, regardless of the timeframe. Performing this simple step is a cornerstone of effective essential HVAC maintenance tasks and directly impacts your indoor air quality. Neglecting this is one of the top causes of HVAC system failure.
Remember, consistent filter changes are fundamental essential HVAC maintenance tasks for efficiency and longevity.
