Evaporator Coil Installation & Repair

Need to repair or replace your AC’s evaporator coil? Call (516) 671-3232 for professional repair and replacement service.

Your air conditioner is an intricate collection of different mechanical parts working in harmony. With several key components located outdoors, you would figure that these parts would need more maintenance than the indoor portions. However, your inside air conditioning unit houses one of the most important parts: the evaporator coil. At Maccarone Plumbing, we provide professional evaporator coil services for residents and commercial site owners throughout Long Island and Five Boroughs.

How Does the Evaporator Coil Work in Relation to Your AC Unit?

A refrigerant liquid moves from your outdoor AC unit to your indoor portion. As it enters the evaporator coils, the refrigerant changes from liquid to gas. As the gas evaporates, it absorbs heat from the surrounding airflow supplied by the system’s fan. Most evaporator coils use a system of fans to create a larger surface area for air to strike, thus creating a larger and cooler air flow. The resulting cool air flows out of the evaporator coil area and into the ducts for distribution around your home or business. Any moisture pulled from the hot air condenses into a pan and out of a drainpipe. Without a properly functioning evaporator coil, your AC unit simply expels hot air.

What are Common Problems?

We have seen many evaporator coils with similar problems. One of the most common problems is freezing. Your air filter plays an important role within your AC unit by trapping debris. If the filter is dirty, it stops airflow across the evaporator coils. Reduced airflow hinders the evaporation process, allowing condensate to freeze on the coils themselves.

Evaporators can even freeze if too much dirt or debris settles on the fans. Systems running with no filter at all quickly accumulate dust on the evaporator, leading to significant damage from freezing.

Refrigerant leaks can also lead to frozen evaporator coils. Leaking between the outdoor and indoor systems, such as from a tear or hole in the hosing, creates a low flow at the evaporator. Reduced refrigerant liquid in the system will then cause the AC to work harder to reach the set temperature. The evaporator coils freeze from the added strain on the system to keep your building cool.

When is it Time to Replace Your Evaporator Coil?

Unless your AC unit has a manufacturing defect, the evaporator coil should be consistently serviced and maintained for approximately 10 years. If your evaporator fails between 7 and 10 years, it is time to replace the assembly. Its energy efficiency may be declining and parts can be difficult to find.
