Airflow Of A Evaporator Coil In A Attic Hvac Unit

When the temperature of the coil is below the dew point of the air moving over it there is also a transfer of latent energy from the air as some of the water vapor in the air condenses to liquid water condensate on the evaporator coil.

Airflow of a evaporator coil in a attic hvac unit.

I had a two and a half ton unit put in my attic and it sounds like a diesel truck running all time my other unit was 6 years old and you could not hear it run m y house is 7 years old and the coil went out in it my electric bill went from 140 00 to 278 00 this unit is half the size of the older one it looks like a closet unit for a small. The weaker the coils the more prone they are to developing refrigerant leaks. The evaporator coil is the part of your ac system that actually cools the air before it is blown into your home. Can a dirty furnace coil affect heating.

Your evaporator coil is an a shaped web of copper coils that sits inside your indoor ac unit. Over time the refrigerant flowing through the evaporator s coils wears down the inner lining making the coils weaker. Technically the evaporator moves the heat from the air into the refrigerant and the cooled air is then blown into the home through the ductwork. Dirty coils use up to 40 more energy than air conditioning units with clean coils as well as reducing the cooling function by an estimated 30 or more.

The coil is a heat exchanger giving you hot or cold air depending on the time of year. Airflow is the lifeblood of a central heating ventilation and air conditioning system. Accessing the evaporator coil on attic unit doityourself munity forums. The evaporator coil works when air flows over a series of thin metal fins that are cooled by the refrigerant within the copper tubing.

Among the first items an hvac technician will check on a service. Also if main pan is metal we could have a hole rusted through allowing water to drip in overflow pan. It may be possible that the coil is actually icing up due to one of the things mentioned low air flow from dirty coil or blower wheel or refrigerant charge. Air conditioner leaking water how to clean your ac coils and when 21 air conditioner maintenance and home blockage from a clogged ac drain line air conditioning and heating system skip to content.

Most homeowners never actually see the evaporator coil because it is covered by a metal case that is usually in an indoor closet or attic. As the hvac blower draws air from inside your home across the coil the refrigerant evaporates as it absorbs the heat from the air.
