If you are moving into a home for the first time that has central air conditioning, you may be looking forward to having your home feel much more comfortable in the summer. However, the central air conditioning system can break down over the years from the wear and tear of running it. Here are some common problems that could arise with central air conditioning.
A central air conditioner works by taking a highly pressurized refrigerant and pushing it through a tube until it reaches an evaporator coil. The refrigerant causes the coil to absorb the heat in the air, which cools the air before it is pushed through the vents in your home. The refrigerant then makes its way back to the compressor outside where it continues through the loop once again.
A problem that can happen is with a leak somewhere in the refrigerant lines. It causes the refrigerant to leak out of the system, which depressurizes it, causing the evaporator coil to fail at removing heat from the air. If this happens, you'll need to have the system inspected by a professional.
An HVAC repair specialist will start by putting a dye into the system to identify where the leak is located. They'll repair the line, and then add more refrigerant back to the system so it is pressurized. If the leak is not found before adding more refrigerant, it will all leak out of the system once again.
Dirty Air Filters
All the air that goes through your home must travel through the air filter. This helps remove dust, dirt, debris, and allergens from the air, which makes the air cleaner to breathe. Unfortunately, the filter is a part that needs frequent cleaning or replacement, and it can affect the entire system.
A dirty filter makes the air conditioner do more work to push cold air through the filter. A dirty filter also causes the air conditioner to run longer to make your home cold, which puts more wear and tear on the system. Dirt will also collect on the evaporator coil much easier, which results in the coil having a harder time removing heat from the air to chill it.
This means that ignoring the filter also means you'll need to have the evaporator coil cleaned. If not, it puts even more wear on the air conditioner to provide cold air for your home.
