HVAC Maintenance — The 15-Point Annual Inspection
Annual tune-ups keep a furnace, heat pump, or geothermal system running at rated efficiency.
Why Annual Maintenance Matters
Our 15-point inspection walks every failure point on a furnace, heat pump, or geothermal system — blower motors, capacitors, refrigerant charge, heat exchanger, combustion draw, thermostat calibration. Catch problems before they cost you.
Keeps Systems Running Efficiently
A well-maintained furnace or heat pump runs at rated efficiency — and costs less to operate.
Prevents Unexpected Failures
Annual inspection catches problems before they become emergencies — especially important before heating season.
Preserves Warranty Coverage
Many HVAC system warranties require annual professional maintenance to remain valid.
Catches Small Problems Early
A worn blower motor, low refrigerant, or failing capacitor is cheap to fix now — expensive when the system dies mid-winter.
Combustion & Heat Source
Heat Exchanger Inspection
Check for cracks, carbon traces
Flame Sensor & Igniter
Clean, verify µA reading
Gas Pressure Check
Measure inlet/manifold pressure
Refrigerant & Coils
Refrigerant Level
Check subcooling/superheat, no leaks
Evaporator Coil
Clean, check for ice formation
Condenser Coil
Clean fins, check for damage
Electrical
Capacitor & Contactor
Measure capacitance, inspect contacts
Electrical Connections
Torque check, corrosion inspection
Thermostat Calibration
Verify temperature accuracy
Airflow & Filtration
Air Filter
Inspect/replace
Blower Motor
Clean wheel, check amperage draw
Condensate Drain
Clear, treat with biocide tablet
Safety & System Controls
CO Detector Test
Verify operation
Duct Integrity Check
Visual inspection for leaks/damage
System Performance Test
Measure supply/return delta-T baseline
Seasonal Preparation
Before Heating Season (September–October)
- ✓Furnace/heat pump clean and operational check
- ✓Thermostat calibration
- ✓Gas pressure and combustion check (gas systems)
- ✓Heat exchanger inspection
Before Cooling Season (April–May)
- ✓Air conditioning operation and charge check
- ✓Condenser coil cleaning
- ✓Refrigerant levels
- ✓Compressor performance test
Warranty Preservation
Most HVAC system warranties require professional annual maintenance to stay valid. Skipping maintenance can void expensive warranty coverage.
We'll document every maintenance visit so you have proof of compliance if you ever need to file a warranty claim.
