Because of the chemical properties of the refrigerant, when heat is not absorbed into the coil for a certain amount of time, it freezes.
So, what prevents the presence of hot air around the coil?

Airflow is somehow being cutoff, which can mean one of several different things:
- Dirty air filter. Dirt and debris are blocking warm air from entering the return vent. OR a household object – like a sofa or blanket – is in the vent’s way and blocking air flow.
- In a less common scenario, your air duct has collapsed due to wear and tear, bad installation, or pests, and air from the return vent cannot reach the coil.
- Dirty evaporator coil. The evaporator coil is covered in a layer of grime and air cannot pass through it. If dirt has made its way into this area, you may have a defective filter or cracks/fissures in your air ducts.

Additionally, your indoor air may start to smell musty if you have a frozen coil due to the development of bio-growth.
If your air conditioning system seems intact and clean, your system might be low on refrigerant, leading to a frozen evaporator coil.
So, Your AC Blowing Warm Air Could Be Due To A Refrigerant Leak.
We explained how the refrigerant, when put under pressure, gets hotter. The same is true of the inverse. With low refrigerant levels, the chemical liquid in the coil expands, cooling it until it freezes.
Because your AC is a closed-loop system, if your refrigerant is low, it is escaping the refrigerant line through a leak. And once the coil has frozen over, your AC cannot extract the warmth from your home’s air. It is simply sent back un-conditioned.

Don’t try fixing the freon leak yourself. Call an HVAC technician to do a “leak search” to locate it, repair the hole, and add the correct refrigerant into the evaporator coil to normalize the levels. For those of you living in Maryland, you can get AC help here.
Your AC not blowing cold air as a result of dirty condenser coil.
Your outdoor unit houses the other end of the coil, where the refrigerant arrives as a hot vapor and is released into the outdoor air.
