How Often Should I Service My HVAC System?
Regular HVAC maintenance is essential for keeping your system running efficiently, extending its lifespan, and preventing costly repairs. But how often should you service your system? The answer depends on the type of system you have, how frequently you use it, and your indoor air quality needs.
General HVAC Maintenance Guidelines
Heating and Cooling Systems (Furnace + AC or Heat Pump)
Recommended Service: Twice a Year
Your air conditioner should be serviced in the spring before the cooling season begins.
Your furnace or heat pump should be serviced in the fall before you rely on heating.
Furnace-Only or Heating-Only Systems
Recommended Service: Once a Year (Fall)
Before winter arrives, it’s important to have your furnace cleaned and inspected to ensure efficiency and safety.
Mini-Split / Ductless Heat Pumps
Recommended Service: Once or Twice a Year
If your ductless system is used for both heating and cooling, biannual maintenance is recommended. If it’s primarily used for one season, annual maintenance may suffice.
Air Filters
Check Every 30–90 Days, Clean or Replace as Needed
Dirty filters reduce efficiency, increase energy costs, and worsen indoor air quality. If you have pets or allergies, you may need to change your filter more frequently.
Why Regular HVAC Maintenance Matters
✅ Improves Efficiency & Lowers Energy Bills
A well-maintained system runs more efficiently, reducing energy consumption and lowering your utility bills.
✅ Extends System Lifespan
Routine maintenance prevents wear and tear, helping your system last closer to 15+ years with proper care.
✅ Reduces the Risk of Unexpected Breakdowns
Preventative maintenance catches small issues before they turn into expensive repairs or system failures.
✅ Maintains Manufacturer Warranty
Most HVAC manufacturers require annual maintenance to keep warranties valid. Neglecting maintenance could result in denied warranty claims for repairs or replacements.
✅ Improves Indoor Air Quality
Regular filter changes and cleanings help remove dust, allergens, and pollutants, improving the air you breathe.
