During the inspection of the air conditioning system, all parts should be checked to ensure it is working efficiently. The inspection should include examining the outdoor cabinet, refrigerant lines, the indoor unit, and ductwork.
Examine the compressor/condenser unit. Note the presence of an electrical disconnect, clearances around the unit, the condition of the cabinet and fan blade, whether the cabinet is level, whether the refrigerant lines are kinked or damaged, and the insulation on the lines.
Go outside once more to check the outdoor unit. Check fan operation and feel for warm air blowing out of the unit. Also, feel the refrigerant lines for an indication of any problems. The larger line should feel cold and be insulated and the smaller line warm.
Allow the cooling system to continue operating while you listen to the indoor evaporator unit. Check the temperature of air before and after the coil for appropriate differential (14-22 degrees). Note any excessive vibrations, fan motor problems, condensate leaking, or any other issues.
Finally, turn of the system by turning the thermostat back up to either whatever the seller had it set at, or if it was off, turn it back off. Then inspect the indoor unit more closely, checking the condition of the air handler for rusting and corrosion, the presence and condition of the air filter, and the condition of the condensate tray and lines.
If you notice anything out of the norm with your air conditioner, make sure to contact us. We can inspect the system to ensure it is working properly and efficiently for you this summer.
