Reasons Why Your AC is not Blowing Cold Air
When you live in or around Austin, few things are worse than having your air conditioner stop blowing cold air, especially in the middle of the blazing summer.
When this is the case, AC Express wants to help you fix the problem, fast. That is why we offer same-day and emergency service options.
Right off the bat, here are a few reasons why your AC may stop blowing out cold air.
There can be a number of different reasons for this issue to surface, but one factor can focus on the area of the AC coils. Regardless of the location of the two sets of coils, either inside or outside the unit, any dirt or debris that collects on them can either reduce the effectiveness of the air conditioner or render it useless.
These two areas are the evaporator coils on the inside and the condenser coils on the outside. Each of these has some protection from excess dirt and debris by the panel or grill that can be taken out with the use of a screwdriver.
Blocked or Overflowing Drain Pans
Underneath those coils are drain pans that help capture any condensation that drips from the unit. If this isn’t checked on a regular basis, the possibility of the drain pan overflowing exists.
In addition, the piping of the drain pan also needs to be looked at every now and then to make sure that debris is the reason for the AC not blowing cold air. If this is ignored long enough, some A/C repair might be necessary.
Excess or Leaky Refrigerant
What allows the cool air from a unit to enter a residence is a refrigerant, which often means something along the lines of Freon. In some cases, there may be too much of the refrigerant in the unit, while another issue may stem from the presence of a leak.
One easy way to spot this issue is if the unit is starting and stopping on a frequent basis, while another can be detected if a check of the evaporator fans indicates the presence of frost. In this type of situation, it’s almost always better to let experienced personnel fix the issue, rather than try a quick DIY fix.
The cooling air that comes from an AC unit occurs when the fan is set to “AUTO,” and the thermostat is designated for cooling. There are times when each of those circumstances is taking place, but yet no cold air is coming out.
In this situation, the thermostat may need repair or replacement, or the wiring may be need to be assessed. In the latter case, the wiring may be out of sync.
