Easy DIY Air Conditioner Fixes
Do it Yourself Air Conditioner Fixes
It’s but normal to seek the help of an HVAC professional whenever we encounter problems with our air
conditioning system. After all, we’re not trained HVAC technicians, and we always have that fear that
we’ll do our AC units more harm than good if we do the tinkering ourselves.
However, there are some air conditioning problems that we can fix ourselves, especially if we’re the
type who likes doing things the DIY way. That’s why whenever our AC system acts up, the smartest thing
to do would be to do your own troubleshooting first, and you might just be able to fix it without calling
an air conditioning service and spending for repairs.
Take a look at some of these air conditioning problems that just might turn out to be easy DIY AC fixes
AC system is not turning on
You’ve been pressing the power button a few times, yet nothing happens. Before you pick up that
phone to call your trusted HVAC company, make sure that it’s not a circuit breaker that just got tripped.
You wouldn’t want the embarrassment of having to call in a technician only to have him do nothing
more than just flip the breaker switch back on.
Just turn the breaker switch on yourself, and if nothing happens, that would be the time to call an HVAC
AC is not producing cool air
There could be many reasons why an AC unit is not cooling the room anymore. One of the most
common reasons is problems with airflow, which is commonly caused by a dirty air filter.
Aside from causing airflow issues, dirty air filters also make an AC unit work harder to cool the room,
and that can make your energy bills rise more than it should.
So if your AC’s not making cool air, check the air filters and if they’re filthy, clean them or better yet,
replace them with new ones.
If the air filter’s clean or new and you still can’t feel cold air coming out of the vents, then you should
turn the problem over to an HVAC professional because the problem could be bigger and way beyond
Just because an AC unit produces cold air doesn’t mean freezing up is part of the package. On the
contrary, an air conditioner that ices up could be an indication of an airflow problem.
So all you have to do—initially at least—is thaw the unit by turning it off and leaving the ice to melt. If
you want faster thawing, then you can always turn the unit on and set to fan. As for the airflow part of
the problem, cleaning and replacing the air filters ought to do the trick.
Still, an AC unit freezing could be an indication of more serious problems that you cannot DIY. It’s
possible that the unit is low on refrigerant. Worse, however, would be a refrigerant leak, which can be
dangerous. Either way, only an air conditioning technician is adequately trained and equipped to deal
with this sort of problem.
Condenser not releasing heat properly
Your AC system typically has an outside unit tasked with releasing the heat drawn from inside your
home. When your AC is having problems cooling the air inside, it’s possible that the outside unit is very
dirty or the area around it is filled with debris.
We understand that the outside unit is often forgotten, but you should always check it because weed,
dirt, or debris like leaves or broken tree branches could be covering it, making it hard for the outside
unit to expel the heat and cause problems with its operation.
You can also clean the outside unit by hosing it down with water. However, if you’re worried you might
do things the wrong way, you can always call for your trusted AC technician to do it for you.
Always keep in mind that DIY air conditioner fixes are only recommended for the simplest problems, like
the ones listed above.
If you notice signs like burning smells, clattering, thumping, and hissing sounds, then waste no time in
turning your system off and calling an HVAC services company for repairs. You can be sure that those
signs are indicative of much more severe problems, and you wouldn’t want to do anything about them
lest you make it worse. Only skilled, properly-trained, and experienced air conditioning specialists
should touch your AC unit when it’s acting up this way.
