While ACs that fail to run at all cause plenty of concern, there’s an opposite problem that’s every bit as serious. Some ACs simply don’t shut off, failing to go through proper cycles. If this describes the AC in your Sulphur, LA home, we can give you a few common reasons why it runs constantly.
Old or Dirty Filters
Naturally, debris will accumulate on your AC’s filters following normal operations. However, if too much of it gathers, it may choke off airflow, decrease your system’s effectiveness and cause it to work non-stop to keep you cool. Remember to clean or replace your filters at least once every 90 days.
Dirty or Frozen Coils
Normally, refrigerant should condense in your AC’s evaporator coils and its condenser coils, making it possible to generate cool air. However, those coils can get dirty, and various system issues can cause condensation to freeze on the evaporator coils, lining them with ice. If any of these things happen, your system’s performance will drop.
In response, your thermostat may force your AC to work harder in an effort to bring your home’s temperature down to the level you’ve set. As long as the debris and ice remain, though, your system will struggle to keep you cool, possibly never turning off. To take care of this issue, you will ultimately need HVAC maintenance technicians to clean the obstructions away.
Incorrect System Size
Finally, the source of your AC’s unusual behavior may lie somewhere beyond the reach of a simple tune-up or round of repairs. HVAC technicians should have carefully performed a sizing calculation of your home before installing your system, but they may have miscalculated and given you one that’s too small. If so, your AC will need to fight all the time to maintain cool temperatures in your home.
You’ll only be able to take care of this by removing your old system and installing a new one. Make sure that the installers perform a Manual J load calculation.
If your AC runs non-stop, it may be at risk of total failure. To prevent this, call Burnworth’s A/C and ask for AC repairs around Sulphur, LA.
