With Memorial Day approaching next week, most Minnesotan’s are looking forward to the warm temperatures of summer and the activities that go with being outside. Fun 
times in and on Minnesota lakes help keep a person cool when the weather is warm. But, when you have to be indoors, a comfortable temperature and air conditioning is important whether you are working, playing, or sleeping.
Most air conditioning professionals have an Air Conditioning Tune-Up and Maintenance Checklist that involves inspecting, cleaning and watching for other potential issues that may cause a breakdown or inefficiency. Some home owners or facility managers may have enough HVAC knowledge to do some of the inspections themselves, but most rely on a trained HVAC professional for a thorough visual inspection of the exposed duct work, furnace and air handler, condensing unit, and thermostat.
Air Conditioning Maintenance Checklist
With each air conditioning maintenance call, this checklist is completed by the Chappell Central service techs and given to the homeowner for their records.
Exposed Duct Work:
- Check that ducts are intact and properly supported
- Check that registers are open
- Check that return air grills are unrestricted
Air Handler:
- Check motor and blower bearings, lube as needed
- Inspect and adjust belts and pulley alignment
- Inspect blower for vibration and noise
- Inspect condensate pipe for proper installation and function
- Inspect, clean and/or replace air filter
Air Condensing Unit:
- Inspect and tighten electrical connections
- Check crankcase heater
- Inspect condenser fan blades, motor, and bearings, lubricate as needed
- Check condenser oil
- Gauge unit for freon charge and operation
Thermostat:
- Check for proper operation of the thermostat
For most people, completing the Air Conditioner Tune-up and Maintenance on their own is not an option. Consider contacting a home comfort expert before the high temperatures set in to tune-up your air conditioner and be ready for a long summer of cooling.
