Maintenance for home air conditioners and heat pumps
A/C or Heat Pump Tune Up and Inspection Procedures
- Chemically clean and thoroughly wash condenser coils
- Thoroughly clean and/or replace pleated air filter
- Wash and level condensing unit for proper motor and bearing wear
- Lubricate motor and fan bearings as well as other moving parts as necessary
- Clean and inspect evaporator coil and drain pain when readily accessible (additional labor charges may apply for difficult cleaning of evaporator coil)
- Clean and inspect condensation drain lines and fittings
- Clean, level and calibrate thermostat
- Adjust and thoroughly clean blower motor and fan assembly as needed
- Inspect, tighten and test all electrical connections, including disconnect switch
- Inspect all cooling system electrical wires, connectors and terminals
- Test all controls, switches, relays, transformers, contractors, motors and fans
- Measure starting and running amperes, line voltage, and control voltage
- Test system starting capabilities
- Test system for proper air flow and air delivery
- Inspect and adjust all safety controls
- Monitor refrigerant (Freon) pressures and temperatures
- Add up to 1 pound of Freon at no charge
- Test and record superheat and sub cooling. Compare with factory settings.
- Adjust coolant metering control device per factor or manufacturers recommendations
- Test and measure air conditioning system for proper production and capacity
- Monitor fan motors and compressor operating temperatures
- Check for code violations
- Check for outside obstructions or insect infestation
- Apply weather resistant protective coating to the outside unit or condenser
- Complete and present a full written report to customer
Furnace Tune Up and Inspection Procedures
- Check and tighten electrical connections, terminals and loose wires
- Remove, inspect, clean, and adjust main gas burners
- Remove, clean and adjust ignition pilot assembly
- Thoroughly brush, vacuum and clean heat exchangers and combustion chambers
- Examine heat exchanger for cracks, rusting or problem areas
- Vacuum out blower compartment, return, airdrop and surrounding area
- Inspect inside of ducts for debris
- Clean all return air grills throughout the home
- Examine flue assembly and test flue gas drafting mechanism
- Test and inspect furnace safety controls
- Test, record and adjust gas pressure as required
- Replace standard filters with special pleated filters (*extra charge for specialty filters)
- Remove and clean blower motor, drive mechanism and fan assembly
- Lubricate all fan motors and applicable moving parts
- Measure and adjust blower for correct airflow
- Inspect heat anticipator settings
- Monitor air and heat cycles
- Adjust all dampers and set proper blower speeds
- Clean, level, test and calibrate thermostat
- Measure and record heating system output
- Inspect and test thermocouple output as well as pilot safety switch
- Measure and record electrical voltage, amperage and component resistance
- Inspect and test all system transformers, relays, contractors and controls
- Repair minor leaks in plenum and return air drop (ask us about duct sealing!)
- Perform a thorough, room-by-room electronic carbon monoxide check of entire house
- Check for code violations
- Advise you about other ways to reduce energy consumption, improve safety and enhance comfort
