Client states that system was freezing up, system was thawed out upon arrival. Pulled out air filter and found evaporator coil completely plugged and blocked. There was a plastic bag sucked into evaporator coil not letting any airflow pass through. Blower wheel is very dirty as well. Condenser coil is also dirty and needs to be deep cleaned. Gave client solutions for issues with system, however, system is 11 years old and recommend replacing due to age and cost of repair. Client will discuss all options with homeowner and will let us know which solution they would like to go with.
