HVAC technicians perform a number of tasks during air conditioning maintenance services. Regular maintenance helps to identify mechanical issues before they become a huge and costly problem. Air conditioning maintenance checks consist of a thorough examination of all of its parts to ensure it is in top operating condition. Regular AC maintenance services can be viewed almost as a doctor appointment for AC systems. The technician performs a detailed checkup and repairs or replaces parts. It is ultimately up to the owners to take care of those parts. Sound familiar?
Of course, air conditioning maintenance, and its costs, will vary depending on the type of air conditioner whether it is central air/HVAC, window, portable, swamp cooler, or ductless. For this summary, we’ll concentrate on central AC maintenance services.
Air conditioning maintenance technicians typically check both the indoor and outdoor components of an air conditioner. This includes parts, motors and belts. Coolant levels are measured and refilled. Circuits, safety controls, drain lines, pumps, caps and valves are all checked and replaced, if necessary.
Identifying safety issues is important to prevent fires or a carbon monoxide leak. AC electrical components need to be inspected for signs of wear, and replaced to prevent failure or sparking. At the same time, it is important to take measures to prevent dust and debris from entering an air conditioner or duct work.
Identifying mechanical issues ensures uniform heating. Thermostats should be inspected, cleaned and calibrated for the most efficient cooling which ultimately produces lower energy bills and cost savings.
Tasks vary but may include: clean or replace air filter; clean evaporator and coils; inspect all electrical wiring and safety ratings; inspect and repair electrical parts; measure amp and voltage; flush drain lines and look for signs of mold or mildew; test capacitors; test valves and fan blade; check motor amps and voltage; clean all duct work; check refrigerant level; test and calibrate thermostat; check and lubricate bearings; measure temperature; lubricate all moving parts; inspect and adjust coils and fins; inspect belts and pulleys; check air flow of blades and blower wheel; check airflow through evaporator coil; check for debris; check window caulk; and finally, make sure the cooling and heating systems can not run simultaneously.
Costs will obviously vary depending on the type of AC service, repairs and replacement parts. Tuneups typically range in the $200-and-up range. AC maintenance services can be lengthy and complicated, however, it is probably best to hire a professional if people don’t have extensive knowledge about AC operation and repair. It can take an hour to several hours to service a unit.
The purpose of maintaining the AC system in a home or business is to keep the family, or place of business, comfortable and safe. Fins and coils should be inspected, and filters changed regularly. AC systems should be serviced once a year in the spring to ensure they work at their highest efficiency all summer long. A well-maintained HVAC system should last 20 years or more.
