## Monthly Tasks (DIY)

**For Your Entire System:** - [ ] Check and replace air filter (or clean if washable) - [ ] Inspect vents for dust and obstructions - [ ] Ensure furniture isn't blocking airflow - [ ] Listen for unusual sounds during operation - [ ] Check thermostat operation

**Quick Monthly Inspection:** - [ ] Look for water leaks around indoor unit - [ ] Check that outdoor unit is clear of debris - [ ] Verify all vents are open throughout home

## Seasonal Tasks

### Spring (Before Cooling Season)

**DIY Tasks:** - [ ] Replace air filter with fresh one - [ ] Clean outdoor condenser unit - [ ] Remove debris, leaves, and vegetation - [ ] Trim plants to maintain 2-foot clearance - [ ] Clean supply and return vents - [ ] Test AC operation before hot weather

**Professional Tasks:** - [ ] Schedule annual AC tune-up - [ ] Have refrigerant levels checked - [ ] Professional coil cleaning - [ ] Electrical connections inspection

### Fall (Before Heating Season)

**DIY Tasks:** - [ ] Replace air filter - [ ] Check thermostat batteries - [ ] Clean around furnace area - [ ] Test heating operation - [ ] Check smoke and CO detectors

**Professional Tasks:** - [ ] Schedule annual furnace tune-up - [ ] Have heat exchanger inspected - [ ] Burner cleaning and adjustment - [ ] Safety inspection

## Annual Professional Maintenance

### What's Included in AC Tune-Up

A comprehensive AC maintenance includes: 1. Refrigerant level check and adjustment 2. Evaporator and condenser coil cleaning 3. Condensate drain line cleaning 4. Electrical connection inspection and tightening 5. Thermostat calibration 6. Blower component inspection 7. Air filter inspection/replacement 8. System performance test

### What's Included in Furnace Tune-Up

A thorough heating maintenance includes: 1. Heat exchanger inspection for cracks 2. Burner cleaning and adjustment 3. Ignition system inspection 4. Safety control testing 5. Blower motor inspection 6. Gas pressure check 7. Carbon monoxide testing 8. Thermostat calibration

## Signs You Need Service Between Maintenance

Don't wait for scheduled maintenance if you notice:

**Cooling Issues:** - AC not cooling effectively - Ice forming on equipment - Unusual sounds - Water leaks - Short cycling

**Heating Issues:** - Furnace not heating - Yellow burner flame (should be blue) - Burning smells - Frequent cycling - Cold air from vents

## DIY vs. Professional Maintenance

### You Can Do: - Filter replacement - Vent cleaning - Outdoor unit cleaning (gently with garden hose) - Thermostat battery replacement - Visual inspections - Drain line maintenance (pouring vinegar)

### Call a Professional For: - Refrigerant handling - Electrical work - Gas adjustments - Heat exchanger inspection - Coil cleaning (indoor) - Blower motor service - Any repairs

## The Cost of Skipping Maintenance

Neglected HVAC systems: - Use 15-25% more energy - Break down 95% more often - Last 5-10 years less than maintained systems - May void manufacturer warranties

## Bay Area Specific Tips

Living in the Bay Area presents unique HVAC considerations:

**Coastal Areas (Pacifica, Half Moon Bay, San Francisco):** - Salt air can corrode outdoor units faster - Consider corrosion-resistant coatings - More frequent outdoor unit inspection

**Inland/Hot Areas (Livermore, Pleasanton, Concord):** - AC works harder in summer heat - Consider twice-yearly AC maintenance - Check refrigerant before heat waves

**Foggy Areas (Daly City, Pacifica):** - Higher humidity can affect components - Watch for mold in ductwork - Consider dehumidification options

## Creating Your Maintenance Schedule

1. **January**: Check heating system mid-season 2. **March**: Schedule AC tune-up 3. **May**: Prepare for cooling season 4. **July**: Mid-summer AC check 5. **September**: Schedule furnace tune-up 6. **November**: Prepare for heating season

## Final Thoughts

The best HVAC maintenance is preventive. By following this checklist and scheduling professional maintenance twice yearly, you'll enjoy reliable comfort, lower energy bills, and fewer surprises. Your HVAC system is one of the largest investments in your home—protect it with proper care.
