HVAC Maintenance

Scheduled preventive maintenance for heating and cooling systems to maximize efficiency, lifespan, and reliability

💰 $80–$200 per visit / $150–$350 annual plan ⏱ 1–2 hours for a standard tune-up visit ⚡ Proactive — schedule before peak season

⚠️ Warning Signs You Need HVAC Maintenance

  • ⚠ More than 12 months since the last professional HVAC tune-up
  • ⚠ Air filters unchanged for more than 60–90 days (30 days in dusty or pet-heavy households)
  • ⚠ Reduced airflow from vents — a sign of dirty coils, clogged filter, or duct issues
  • ⚠ Longer run cycles with the same thermostat settings — an early sign of efficiency decline
  • ⚠ Condenser coils visibly dirty, bent, or restricted by vegetation
  • ⚠ Unusual increase in monthly energy bills compared to the same month last year

What to Do: Step-by-Step

  1. 1 Schedule AC maintenance in spring (April–May) before the first major heat wave of the season
  2. 2 Schedule heating system maintenance in fall (September–October) before the first cold snap
  3. 3 Change air filters monthly during peak season (summer for Sunbelt AC, winter for heating climates)
  4. 4 Keep the outdoor condenser unit clear of debris, vegetation, and shade structures within 2 feet
  5. 5 Check condensate drain lines monthly — pour a cup of diluted bleach into the drain pan to prevent clogs
  6. 6 Clean or replace air handler coil if you notice reduced airflow or a musty smell from the vents
  7. 7 Consider a maintenance plan from a local HVAC company — typically $150–$350/year and includes priority service during emergencies
