Every large comfort appliance such as the HVAC (heating, ventilation, and air conditioning) system is installed using multiple components. The first is the condenser, which will be placed somewhere outside the building. For most homes, the condenser will sit on a concrete slab close to a wall, but many businesses place this unit on the roof. The evaporator coil is coil mounted in the plenum. The plenum is part of the internal unit and is found just above the furnace portion of the HVAC. This allows the furnace and air conditioner to share the blower and air ducts. Unfortunately, this placement can result in a common issue that requires the help of an Air Conditioning Repair Contractor. Grime collects on the evaporator coil that can reduce functionality or even result in freezing.
A frozen evaporator coil can be a real problem because it may rupture. There are a few possible reasons that a coil can freeze. The first is a low refrigerant level. When the refrigerant level is low, it may not compress correctly, and this could hinder heat collection. Rapid changes in the refrigerant can cause frozen spots. The other issue is dirt. An AC generates condensation, and this is why they all have a drip pan. Unfortunately, this condensation can mix with any dust that gets past the filtration system. This gunk will accumulate in areas of the coil where the airflow is weaker and eventually form a blockage that keeps the moving air from drawing the cold out of the metal coil. The result is a frozen spot and a possible rupture. An experienced Air Conditioning Repair in Homestead FL can remove the coil and clean it in an acid bath before this happens.
One of the most expensive components of the AC is the condenser unit. Condensers are fairly reliable as long as the refrigerant level is maintained. This is because the refrigerant carries vital lubricants that protect the compressor from overheating. Keeping the refrigerant checked is one of the main reasons that the appliance should have annual maintenance. In fact, most manufacturers recommend that the AC is serviced every year, usually in the spring before the appliance is put under a heavy load.
