5 Ways To Tell If You Need AC Maintenance During The End Of Summer

While we often think of August as the “end of summer” as kids are going back to school, it’s usually one of the warmest months of the year.  The average high temperature in St Louis during August is 88 degrees.  Twice since 2016 has St Louis experienced even higher averages than that.  During the midpoint of summer, your AC unit has been working at a high rate for the past couple of months.  There isn’t a better time to make sure everything is working properly.  Nobody wants to be stuck without AC during the hottest time of the year.  Here are some common issues that you can run into after your air conditioning unit has been running consistently throughout a warm summer:

Failing Capacitors

This is a common issue during late summer.  Inside of your AC unit are capacitors that send electricity to the air conditioner’s motors.  When they begin to fail, your AC unit will struggle to provide enough energy to keep the motor working properly.  Motor failure can result in your air conditioner not working.  Trained AC technicians can usually spot and fix this problem easily.

Motors Issues

The summer can be strenuous on your AC’s fan motors.  It is common for these motors to experience wear and tear as they are constantly running.  Oftentimes, the fan motor can be the first thing to start experiencing issues. This is more common in older AC units.  If the fan motor stops working, then your house stops getting cooled.  If you notice strange sounds coming from your AC unit or less and less cool air being pushed throughout your home, it would be smart to have the motors checked out by an HVAC technician.

Low Refrigerant

Refrigerant leaks are not uncommon.  A leak can lead to increased energy bills and poor performance from your air conditioner.  Leaks can also cause damage to the compressor of the machine. Low refrigerant can cause the evaporator coils inside of your AC unit to freeze, which puts a large strain on the unit as a whole. It makes the machine work much harder than it needs to and can cause serious damage that may not be repairable.  Luckily, proper AC maintenance can minimize the likelihood of a leak occurring.

Frozen or Unclean Coils

It’s easy to think the coils of your air conditioner can’t freeze during the hottest months of the year, but it’s simply untrue.  AC units don’t just cool the home, but they also dehumidify the air.  By doing so, air moisture can create condensation build on the evaporator coils.  Frozen evaporator coils are typically caused by airflow or refrigerant issues.  These could be dirty or clogged air filters, or a refrigerant or duct leak. If you notice frost build-up or a frozen AC unit, call a trained HVAC technician to come to perform AC maintenance and make sure no serious damage is done to the air conditioner.

Dirty or Clogged Air Filters

Odds are, your air conditioner is going to run all summer long, or at least a large majority of it.  After constantly pushing air through an air filter, at some point, the filter is going to get dirty or clogged with debris.  It is usually easy to tell when there is an issue with your air filter, as the airflow throughout your home decreases and isn’t as strong as normal.  We have so many things going on in our lives that it can be really easy to overlook or forget about cleaning our air filters.  Our air filters should be cleaned regularly to ensure peak performance from our AC units and for clean air quality in our home.
