“What do you mean my air conditioner can freeze over? It’s
over 100 degrees outside!” This is a fairly common reaction we get
from customers who are shocked to learn that the inside of their air conditioner
has turned into an icy winter wonderland that better resembles Antarctica
in the middle of winter. This unfortunately brings your system to a screeching
halt, stopping your system from producing cold air and mandating that
you keep it off until the problem is resolved.
So what can you do to fix a frozen air conditioner and what about preventing
it from coming back all together? Our Palm Beach County air conditioning
experts have a few tips on this blog.
What Causes Freezing?
Your air conditioner can freeze over for a lot of different reasons, but
there are two primary factors in what cause this issue: low airflow over
your evaporator coil, and an increased concentration in dust or debris
that cause water to condense and freeze, forming ice.
Low air flow is usually caused by a dirty air filter. When your filter
becomes too clogged up with dust, dirt, pet hair, dander, pollen, and
other contaminants, the airflow over your coil is heavily restricted,
resulting in less air moving over the coil, and that means less heat over
your cooling coil. Less heat equals a higher likelihood of condensed water
freezing over, and eventually the issue literally “snowballs”
until the whole coil is frozen. Extra dust or debris moving over your
coil also gives the water vapor in this cool area something to condense
on, further exacerbating the issue and leading to even more ice buildup.
Fixing a Freeze
So when your coil freezes over, what can you do to fix it? The easiest
way to do this is simply shut off your air conditioner for a few hours
and let the existing ice melt away. This may take time, but eventually
your system will restore back to normal. However, that also doesn’t
mean that your air conditioner won’t freeze over again.
Likewise, you may also want to consider switching your thermostat’s
fan setting to “on” which will continue to pull air from your
home over your frosted coil, which could help keep the temperature up
and make the ice melt quicker. However, be careful: keep an eye on your
drain pan to make sure that there are no clogs, because a frozen system
will show you right away if you’ve got this problem.
Keeping Freezing Away
If you want to get rid of the freezing problem for good, the single most
important thing you can do is change your air filter. We find that dirty
air filters are by far the most common cause of frozen air conditioner
coils, and often it’s because the homeowner hasn’t changed
their air filter in months or even years. A quick, simple, and inexpensive
filter change could help eradicate the problem completely.
Another thing you can do is have your ducts cleaned by a Palm Beach County
HVAC professional. A duct cleaning can remove the dust and debris that
has built up in your air intake vent, preventing it from falling into
your coil itself and encouraging frost and freezing. Finally, regular
system maintenance and coil cleaning will also encourage both efficient
operation and prevent freezing by ensuring that your coils stay clean
and clear as long as possible.
