- 1Condenser Coil – Cleaned as required
Dirty condenser coils raise refrigerant pressure higher than needed, increasing your electric bill.
- 2Refrigerant Charge – Checked by superheat/sub cooling method (Thermo charging)
A low or high refrigerant charge can easily go unnoticed and increase operating costs up to 30%. An improper charge can cause compressor shutdown.
- 3Controls & Safeties – Inspected & tested
Controls and safeties that do not function properly can increase operation cost and cause other components to fail.
- 4Relays & Contactors – Inspected & cleaned
Worn contacts and loose wire connections can lead to motor or compressor failure.
- 5Crankcase Heater – Operationally inspected
Crankcase heaters that do not work can lead to a compressor failure.
- 6Unit Wiring – Inspected & loose connections tightened
Loose connections can lead to a motor, control, or compressor failure.
- 7Temperature & Pressures – Taken & recorded
An accurate record of your equipment’s vital data can indicate potential problems, which can be eliminated. A record will be kept with the unit which may reduce emergency service time.
- 8Capacitors – Tested
Bad capacitors can lead to compressor and motor failure.
- 9Unit Disconnect – Tested
A worn or over-heated disconnect blows fuses and is dangerous.
- 10Lubrication – Application to motors & bearings.
Improperly lubricated rotating equipment will eventually fail.
- 11Belts & Pulleys – Inspected & adjusted
Loose belts and worn pulleys decrease air flow, increase operating costs and shorten the compressor’s life. Belts crack and break with age.
- 12Condensate Drain – Checked to assure it is open
Algae and dust can plug a condensate drain which can cause extensive water damage to your furnace.
- 13Air Filter – Replaced at customer’s option
A restricted air filter can cause your air conditioning unit to waste energy and shorten the compressor’s life.
- 14Voltage & Amp – Draw of the blower motor, compressor & condenser fan motors checked & recorded
Improper voltage and amp draw increase-operating costs and can shorten the life of any motor.
- 15Thermostat – Checked & calibrated
Improperly calibrated thermostats cause the unit to run longer than necessary. Every degree your air conditioner operates below 78 degrees can add 5%-8% to the cost of cooling.
- 16Motors – Cleaned & inspected
Dirty motors are less efficient and will fail sooner.
