A proper HVAC inspection goes well beyond a visual once-over. Here's the full 21-point checklist our certified technicians work through on every visit โ so you know exactly what you're getting.
๐ Electrical & Controls
โ
Inspect electrical connections โ Check for corrosion, wear, or looseness; tighten as needed
โ
Test amperage & voltage draw โ Measure blower/compressor loads; compare to nameplate spec
โ
Thermostat calibration โ Verify displayed temperature vs. actual; recalibrate if off
โ
Safety controls operation โ Confirm high-limit, pressure, and rollout safeties trip properly
โ
Contactors, relays & capacitors โ Look for pitting, bulging, or corrosion; replace if out of tolerance
๐ฌ๏ธ Airflow & Circulation
โ
Blower wheel inspection โ Check dust buildup or imbalance affecting airflow and noise
โ
Air filter condition โ Inspect for restriction; replace or upgrade to maintain airflow
โ
Duct connection integrity โ Seal leaks; address insulation gaps that waste energy
โ
Airflow & static pressure test โ Verify supply/return balance with anemometer or static readings
โ๏ธ Refrigeration & Cooling Circuit
โ
Measure refrigerant pressures โ Record high/low sides; compare to manufacturer spec and ambient
โ
Condenser coil condition โ Inspect for debris or bent fins; clean and comb if needed
โ
Evaporator coil condition โ Check for dust or ice that signal airflow or charge issues
โ
Refrigerant line inspection โ Verify insulation integrity and secure mounting
๐ฅ Heating Components
โ
Burner & ignition assembly โ Inspect burners and igniter for corrosion; ensure proper sequence
โ
Flame sensor & safety shutoff โ Verify reliable flame sense and gas valve shutoff timing
โ
Heat exchanger inspection โ Visual check for cracks or hot spots; document condition
โ
Temperature rise measurement โ Measure ฮT across heat exchanger; confirm within spec
๐ง Drainage & General Condition
โ
Condensate drain line โ Check and flush to remove algae or debris blockages
โ
Drain pan & pump โ Verify slope, pump operation, and absence of leaks or overflow
โ
System cabinet & insulation โ Inspect for rust, vibration, loose panels, or missing insulation
โ
Performance documentation โ Record readings and note recommended repairs or optimizations
