- AC inspection and tune-up includes:
- Thermostat: Check for loose connections that may cause unit short cycling. If possible, check or calibrate temperature readings.
- Split Temperatures: Measure temp drop as air passes through the evaporator coil. The ideal temperature drop should be approximately 17-20 degrees.
- Air Filter: Inspect and advise on existing air filter by looking for debris that may be restricting airflow in the return and try to inspect the face of the indoor coil.
- Blower Wheel: Check for proper operation and ensure for proper balance. Check to make sure the blower wheel is clean and free of build-up.
- Air Ducts: Make sure air ducts are clean and free of growth. Look for signs that may indicate leaks in ducts. (Cold air in attic or insulation in ducts).
- Disconnect Box: Make sure all connections are tight. Look for signs of metal fatigue or signs of overheating (bluish-green).
- Fuses – Check fuse condition. If the fuse is swollen or bad, check disconnect box for loose connection or leaks that may be allowing water inside.
- Contactors: Check switch for worn or pitted points. Check part for possible discoloration or burnt wires.
- Start Kit / Relays / Transformers: Inspect all parts for loose wiring or worn out parts, and ensure parts are securely mounted.
- Run Capacitors: Check microfarads on all caps. Recommend replacement if they are not within 10%. Check for oil leaks or voltage drop.
- Compressor: Check starting amp draw along with running amps. Compare to unit ratings. Look for burnt wires at the compressor terminal.
- Refrigerant: Check system pressures to ensure proper charge on the unit. If the system needs more than 2 lbs do not add refrigerant until the leak is found and repaired.
- Condenser Motor: Check amp draw against max ratings. If needed, oil motor. Check for loose bearings or damaged fan blades.
- Blower Motor: Check motor amperage and compare it to motor ratings. Oil motor if needed. Check to ensure proper motor speed.
- Evaporative Coil: Check and make sure both sides of the coil are clean. Dirty coils will cause poor system performance, early breakdown, as well as poor indoor air quality.
- Condensation Drain: Make sure the drain is free of debris and bacteria growth. Check PVC for loose or cracked parts. Look for overflow signs (rust).
- Plenum: Make sure plenum (elbow) is sealed correctly and that no air is escaping to the outside. 8 out of 10 elbows leak, usually underneath.
- Insulation: Check the insulation by the blower to make sure it can’t be sucked in. Check tubing on the suction line. Worn insulation affects system efficiency.
- Safety Controls: Check to make sure that safety and high-pressure controls are functioning.
- Furnace inspection and tune-up includes:
- Thermostat: Check for loose connections that may cause unit short cycling. If possible, check or calibrate temperature readings.
- Air Filter: Inspect and advise on existing air filter by looking for debris that may be restricting airflow in the return and try to inspect the face of indoor coil.
- Blower Motor: Check motor amperage and compare it to motor ratings. Oil motor if needed. Check to ensure proper motor speed.
- Runs Capacitor: Check microfarads on all caps. Recommend replacement if it is not within 10%. Check for oil leaks or voltage drop.
- Blower Wheel: Check for proper operation and ensure for proper balance. Check to make sure the blower wheel is clean and free of build-up.
- Carbon Monoxide: Test furnace and plenum with meter for any possible leaks. Test all supply registers with a meter for any possible leaks.
- Burners: Check for a solid blue flame. If the orange or yellow flame appears, look for cracked heat exchanger, dirty burners, or poor exhaust flow.
- Heat Exchanger: Examine heat exchanger for cracks or signs of stress or fatigue. Shut down the unit if you suspect that there may be a problem.
- Gas Lines: Inspect all gas lines for possible leaks. Use soap and bubbles and check commonly known areas where leaks often do occur.
- Temperature Rise: Determine changes in temperature between supply & return air. Check this with the allowable rise listed on the unit’s rating plate.
- Safety Controls: Check the door safety switch sequence of safety operations. Also check all other auxiliary safety devices.
- Indoor Coil: Check the indoor coil to make sure it is not restricting airflow. Check for possible leaks that may decrease systems performance.
- Drafting: Ensure proper flame. Look for signs of rust or blockage. If signs exist, look to see if the flue needs to be cleaned or replaced.
- Limit Switches and Fan Controls: Check limit control for proper cut-in & cut-out. Disconnect the power to the blower and test the upper limit switch.
- Pilot / Ignition Switch: Check for flame quality and roll out. Look for hard ignition or any sign of delayed ignition. Check warm up time.
- Duct Work: Check both the supply and return air ducts cleanliness. If in the attic, check to see if any air ducts have collapsed or separated.
- Heat Strips: Check sequences, fan continuity, safety controls, limit switches, and element connections. Check amperages throughout.
- Crank Case Heater: Use an amp probe to ensure the crankcase heater is functioning. If it is not, the oil may foam and reduce compressor viscosity.
- Defrost Controls: Try to send the unit into defrost to check its function. Inform occupants of what they can expect during defrosting.
- Split Temperatures: Take split temp to measure efficiency. Poor split temps indicate bad airflow.
