AIR CONDITIONING MAINTENANCE CHECKLIST
1. Condenser Coil Cleaned as required
Dirty condenser coils raise refrigerant pressure higher than needed, increasing your electric bill.
2. Refrigerant Charge Checked by superheat/subcooling method (Thermocharging)
A low or high refrigerant charge can easily go unnoticed and increase operating costs up to 30%. An improper charge can cause compressor shutdown.
3. Controls & Safeties Inspected & tested
Controls and safeties that do not function properly can increase operation cost and cause other components to fail.
4. Relays & Contactors Inspected & cleaned
Worn contacts and loose wire connections can lead to motor or compressor failure.
5. Unit Wiring Inspected & loose connections tightened
Loose connections can lead to a motor, control, or compressor failure.
6. Temperature & 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.
7. Inspect Duct work
Ripped or disconnected duct causes higher utility bills and reduces efficiency of the unit.
8. Capacitors Tested
Bad capacitors can lead to compressor and motor failure.
9. Unit Disconnect Tested
A worn or over-heated disconnect blows fuses and is dangerous.
10. Lubrication Application to motors & bearings if accessible and needed.
Improperly lubricated rotating equipment will eventually fail.
11. Condensate Drain Checked to assure it is open
Algae and dust can plug a condensate drain which can cause extensive water damage to your furnace.
12. Air Filter Replaced at customer option ($10 Value)
A restricted air filter can cause your air conditioning unit to waste energy and shorten the compressor's life.
13. Voltage & 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.
14. Thermostat 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.
15. Cool-Tech Heating and Air Conditioning also provides 1 free pound of Freon / Refrigerant only if needed. ($45 Value)
Kicked Butt. Your Search Just Ended.....Hire These Folks
Had a Goodman Rooftop Unit installed on Christmas Eve. Impressed with the communication as this was facilitated entirely over the phone at our rental property. Tenant told me Cool-Tech was very courteous, polite and all business. Photos were emailed to me and I was notified when it was done, 3 hours ahead of schedule and in one day. all relevant documents, invoices, estimates etc. were sent to me quickly and without asking or lag time. unit is working well and heats quickly and very quietly. Warranty is solid, please remember to register your unit. it only takes a few mins. I have read that the install is crucial to the longevity of the unit. This install was meticulous with attention to detail. Wish Cool-Tech a bright and prosperous future and thank you so much for the Christmas Eve install as our tenant had people over for Christmas. Check their other page for numerous other reviews. The common theme is they kick butt.
