Beware of These Late-Season AC Issues

Late-season breakdowns are more common than you think. After your HVAC has been put through the wringer with summer and maybe even an unseasonably warm fall, this is the time of year when your unit is most likely to fail. Here are some AC issues that merit a call to your local Longwood AC company before they worsen.


Clogged Filters and Dirty Coils

One of the silent killers of AC units later in the season is constricted airflow. Come December, your air filter is likely loaded with dust, dirt, and pollen, unless you’ve been keeping up with switching it out every month. But even if you have, the outdoor condenser coil can impact airflow just as much.


Dirt and dust restricting airflow force your AC to work harder to produce the same amount of cooling. This can eventually lead to the evaporator coil freezing over, even on a warm day. If you notice this issue, turn off your unit and call an HVAC technician.


Electrical Component Damage or Failure

Heat is hard on electronics. And most of the components in your unit have been subjected to intense heat all summer long. It’s common for some components, like capacitors, to give up late in the season.


If you hear humming but the fan isn’t moving, that’s likely a failed capacitor. Just call a Longwood AC company to fix it before it impacts your compressor, which is a much more expensive component to replace.


Why You Should Call a Longwood AC Company for Your “Minor” Issue

Why bother with AC when winter is right around the corner? Because small issues caused by summer stress can compound quickly, even if you barely use your unit for the next few months.


Many AC companies have hands-on experience with “minor” problems snowballing out of control. A good example is a clogged drain line. Some homeowners opt to ignore this and deal with it in the spring. But if you don’t clear it promptly, it can back up and shut your system down entirely or even cause water damage.
