Why Won’t My Air Conditioner Turn Off?

Sometimes you probably feel like you never want your air conditioner to
stop running, ever. But other times you might feel like your home has
turned into an icebox and you scratch your head wondering why the system
is still pumping cold air. Well, your air conditioning system should in
fact, cycle on and off, so if it’s not shutting down at all, you
have a problem on your hands.

Let’s face it — even during the hottest days of summer, you
probably don’t need your system running 24/7. Since you’re
a savvy homeowner and you’ve properly set your thermostat to kick
on only when the temperature in your home surpasses a certain level, and
only at certain times of the day or night, it’s time to figure out
why it just won’t turn off. Here are a few of the most common reasons:

A Frozen Evaporator Coil

Notice that your system actually isn’t pumping cold air any longer,
but it is still running ‘round the clock? This could mean the evaporator
coil froze up and the system needs to be turned off manually. Doing so
will allow it to thaw out until a professional arrives.

A Faulty Thermostat

Sometimes, it’s not the actual cooling components that are the problem
at all. It could be an issue with your thermostat. Double check the temperature
setting to make sure that the temperature in the room is in fact colder
than the set temperature, before calling in an expert.

If the temperature in the room is colder than the set temperature and the
system is still running, the thermostat may need to be recalibrated.

Leaky Ducts

If the ductwork in your home is old, the system might be leaking cool air.
If enough cold air escapes through cracks or gaps in the ducts, the living
areas of the house may never get cool enough to reach the set point, in
which case, the system would not shut down.

The Wrong Sized System

A properly sized air conditioning system is vital — and it’s
definitely not a one-size-fits-all type of scenario when it comes to choosing
one. It’s best to consult with a professional to find out whether
or not your current cooling system is the appropriate size, and what your
best options are if it is not.
