One of the sounds of summer that homeowners like to hear is that of the air conditioning unit going on and off. The struggle to maintain a cool indoor climate often causes people to just leave the equipment on nonstop. The home stays very cool, but the bills are high. A good air conditioning service program increases the efficiency of the system, making it a valuable weapon in the war against expensive utility bills, as well as the heat.
Refrigerant
The outdoor unit contains the compressor and condenser coils. The compressor pumps refrigerant into the condenser, transforming it from gas to liquid form, expelling heat. The liquid passes through the expansion valve and begins the conversion from liquid to gas and the process is aided as the refrigerant is forced into the evaporator. As liquid evaporates, it absorbs heat and the process keeps the evaporator cool.
Air Cycle
Good airflow throughout the system is essential and the following is how the air cycle works: the blower fan has a secondary function and pulls ambient air into the ducts and the return air vent is high up where the warmest air resides. On the way to the evaporator coil, the air passes the filter, travels through the coil where it cools off on its way to the cooling ducts. Finally, it exits the duct at the cooling vents in the home.
Filter
Changing the filter once a month helps the airflow and ignoring it has the same impact as low refrigerant. Air conditioning service providers check this first when called to repair a unit that is not functioning.
Condenser
Keeping the area around the unit clear of toys, plants, and anything else that may block airflow is essential. The fan helps to dissipate heat by blowing across the coils and the suction this creates pulls in environmental debris.
Ducts
An often ignored maintenance chore is vacuuming the ducts. With the vent removed, the hose can be placed into the cooling duct and debris will be sucked up so that it no longer blocks the passage. The return air vent needs a good annual cleaning, as well.
By knowing how the system works, homeowners can keep them clean and operating well until there is a real problem. When the issue is something that is out of homeowners' depth, they should not hesitate to consult an expert air conditioning service.
