Recommended HVAC Service Frequency

Most HVAC systems should be serviced at least once per year, but ideally twice per year—once before cooling season and once before heating season.

System Type	Recommended Service
Furnace	Once per year (fall)
Air Conditioner	Once per year (spring)
Heat Pump	Twice per year

Why HVAC Maintenance Matters

Prevents breakdowns: catches issues early
Improves efficiency: lowers energy bills
Extends lifespan: reduces system wear
Improves air quality: cleaner airflow

Typical HVAC Maintenance Schedule

✔ Annual professional inspection
✔ Clean coils and components
✔ Check refrigerant levels (AC)
✔ Inspect electrical connections
✔ Test system performance

Filter Maintenance (Most Important DIY Step)

Changing your air filter regularly is one of the easiest and most effective ways to extend HVAC lifespan.

Recommended Air Filters

• Maintain airflow with 16x25x1 air filters

• Replace clogged filters using 20x20x1 air filters

Replacing filters every 1–3 months can significantly improve performance and reduce system strain.

What Shortens HVAC System Lifespan

Regular maintenance is the single most effective way to extend system life and avoid costly repairs.
