My mother has asthma and tells me she needs the AC on almost year round. The AC unit is outside the condo we own, and it connects to the coils in the heater/ventilation system.
We are experiencing poor cooling, (not enough cold air circulating - temp is not low enough) and ice where the coils are:
- What should I do to fix this situation now, and in the long term?
Since she is home alone often I need to understand what causes this so I can perform proactive maintenance, rather than responding to emergencies and giving her unnecessary distress and anxiety.
