How Does an AC Unit Work?
A typical air conditioning unit normally includes the following components:
- An internal section containing the evaporator coil and fan to circulate the cooled air.
- An external section that houses a fan, condenser coil, and compressor.
- Copper tubing allows coolant to flow between the internal and external units.
- A thermostat that controls the temperature of the cool air.
- Air ducts that allow air to circulate from the indoor around your home.
- A thermal expansion valve that controls the amount of coolant going into the evaporator coil
A fan in the internal section takes the warm air from inside the house and blows it across the evaporator coil. The coils absorb the heat and humidity from the warm air and the now cool air is circulated back into your home. Within the evaporator coil is a cold coolant in a liquid state, this changes to a warm gas after it absorbs the heat.
The compressor moves the warm gas around the AC system through copper pipes. It also compresses the gas and as a result, the gas is hotter and at a higher pressure. The hot gas now enters the condenser and with the help of cooling fins, the excess heat is lost to the outside air. This process is helped by a fan blowing the outside air over the condenser and cooling fins.
The coolant having lost its heat now changes back into a cold liquid and moves back towards the evaporator coil and the cycle repeats itself. Before it enters the evaporator coil it passes through a thermal expansion valve which controls the flow of the cold liquid into it.
Some Signs that Mean You Need an Air Conditioner Repair
AC units are normally very robust systems, but they break down occasionally and require an air conditioner repair. To avoid this, you need to be on the lookout for certain telltale signs.
Coolant Is Leaking
If the coolant has leaked from your unit, then you may start to notice the amount of cool air starts to fall off. Every AC unit needs an ideal level of refrigerant within it, as less coolant will mean less cooling. The AC unit will need to work harder to maintain the temperature in your home. This can cause the compressor to overheat and need an air conditioner repair. Your energy bills will also increase due to the system overworking.
Frozen Evaporator Coil
A reduced amount of coolant can cause the evaporator coil to freeze. You will probably see frost and ice forming on the coil first. You should act quickly before the coil is damaged and needs replacing.
Other factors that can cause the coil to freeze are a reduced airflow and if the coil is dirty. Reduced airflow can be caused by a faulty fan not blowing enough warm air over the coil or by dirty intake grilles or air filters. Any dirt settling on the coil will act as an insulating layer and will reduce the rate of heat transfer between the warm air and cold coolant.
Regular service from K&S will help prevent these problems by cleaning the evaporator coil, the inside of the AC unit, topping up the level of the coolant, and replacing dirty air filters. Failure to do this could mean an expensive air conditioner repair bill.
Condenser Is Dirty and Airflow Is Blocked
Because it is outside the condenser and cooling fins can get coated with a layer of dirt. This layer reduces the transfers of heat from the condenser to the outside air and will need to be cleaned off periodically. Weeds and moss can also grow and block the flow of air over the condenser and fins.
A faulty fan will also lead to a reduction in the airflow, as the amount of heat transferred is reduced, there is a less cooling effect produced so less cool air in your home. Failure to remove any blockages or dirt could the condenser to overheat and you needed to pay for an air conditioner repair.
How Old Is Your HVAC Unit?
Even the best-maintained AC unit will have to be replaced after 10 to 15 years. As a homeowner in Rockwall, TX., having an energy-efficient home is one of the smartest moves you can make not only financially, but environmentally as well.
A new AC unit may have a large upfront cost but will be cheaper to run in the long run and use coolants that are not so damaging to the ozone layer. A newer well-maintained unit will reduce the need for an expensive air conditioner repair.
