Benefits of Regular Maintenance
Lower energy bills with a well-maintained system
Of breakdowns can be prevented with maintenance
Extra years of equipment life with regular care
Why Maintenance Matters
- Prevent breakdowns — Catch worn parts before they fail, often during extreme weather
- Lower energy bills — Dirty, neglected systems work harder and cost more to operate
- Extend equipment life — Well-maintained systems last years longer than neglected ones
- Maintain warranty — Many manufacturers require annual maintenance for warranty coverage
- Improve air quality — Clean systems circulate cleaner air throughout your home
- Ensure safety — Identify potential carbon monoxide hazards and electrical issues
When to Schedule Maintenance
- Air Conditioning: Spring (March-May) before cooling season
- Heating: Fall (September-November) before heating season
- Heat Pumps: Both spring and fall for year-round operation
What Happens Without Maintenance?
Neglected HVAC systems develop problems over time:
- Dirty coils reduce efficiency by 20-40%
- Clogged filters restrict airflow and strain motors
- Refrigerant leaks slowly reduce cooling capacity
- Electrical connections loosen and create hazards
- Moving parts wear without lubrication
- Small issues become major repairs
