Regular A/C maintenance is a must if you plan to use your cooling system to the fullest. But few homeowners know what to expect when it comes to system upkeep, especially if they rely on the services of a trained HVAC contractor. Here are four crucial tasks that your contractor should always perform during routine A/C maintenance.
Overall System Check
Your HVAC contractor should perform a check of the air conditioning system to ensure that everything is working smoothly and efficiently. This includes a careful inspection of the blower fan, evaporator coil and other components that make up the air conditioner.
Although you have probably cleaned parts of your cooling system before, there are places you might not be able to reach, or for which special tools might be needed. An experienced tech will thoroughly clean the blower fan, evaporator coil and other parts of your A/C unit of any dust, debris or mold growth. If the air filter needs to be changed, your HVAC technician can do this, as well. An HVAC professional should also make sure the air conditioner’s outdoor components are not impeded by tall grasses, weeds, shrubbery or other obstructions.
Inspect and Lubricate Moving Parts
Have your contractor inspect and lubricate the blower fan motor. He or she should also take a look at the blower fan belt, if the A/C unit uses one. Overly loose belts should be readjusted, while frayed or cracked belts should be replaced immediately.
Check Refrigerant Levels
A qualified HVAC contractor should check the A/C system for any signs of refrigerant leakage. This involves measuring current refrigerant levels and conducting a thorough inspection of refrigerant lines and fittings. The evaporator and condenser coils should also be checked for pinhole leaks and other damage.
