Awakening Your AC: The $200 Investment That Saves $2,000
Spring preparation ensures your air conditioning system operates efficiently through the demanding summer months while preventing costly mid-season breakdowns.
DIY Spring Maintenance Tasks (Time: 2-3 hours, Cost: $50-$100):
1. Air Filter Replacement and Upgrade
Monthly Task (Critical):
- Remove old filter and inspect condition
- Note filter size (length × width × depth)
- Check MERV rating (8-11 recommended for most homes)
- Install new filter with arrow pointing toward blower
- Mark calendar for monthly replacement
Filter Selection Guide:
- Fiberglass (MERV 1-4): $1-$3 each, minimal filtration
- Pleated (MERV 8-11): $8-$15 each, optimal balance
- High-efficiency (MERV 13-16): $15-$25 each, may restrict airflow
- HEPA (MERV 17-20): Requires system modification

- Filter completely blocked (emergency replacement)
- Excessive dust on system components
