Air conditioning season is coming, and when our summer heat waves hit, you need to be on guard for any problems with your system. Only trained professionals should attempt to diagnose (much less repair) an air conditioner. The system contains potentially dangerous chemicals, and without formal licensing any attempt at repairs could be unsafe.
However, that doesn’t mean you can’t learn to spot the signs that something is wrong, then call in a repair service to take care of it. Among the more subtle symptoms of trouble is the presence of frost or ice on the coils. At first, it doesn’t sound like a big issue. After all, isn’t the air conditioner supposed to be cold? In point of face, however, frost on your air conditioning coils is a sign that you need to turn off the system immediately and call in a repair service.
