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
