5 Reasons Why Your AC Might Be Struggling

If you’re feeling hot or sticky indoors, don’t waste energy by cranking up your AC. There are a number of reasons why you might be having problems keeping your home cool. Discover 5 reasons why your AC might be struggling.

Improper Installation If your AC wasn’t installed by professionals or isn’t up-to-date, you might run into a few issues, such as an improperly sized unit. Too small of a system can’t adequately cool your home and too big of a system will frequently shut off; unable to complete a full cooling cycle and won’t dehumidify the air. Both of these issues make your system work harder causing inefficiency, breakdowns, and costly energy bills.

Dirty Air Filters The air filter in your HVAC system is there to protect the inside components from dirt and debris that affects performance, it does not protect your indoor air quality directly. Changing your air filter every 1-3 months prevents airflow restriction; a clogged filter will make your AC work harder.

Refrigerant Leak Refrigerant never runs out, your AC is supplied with enough to last its entire lifespan. If you notice your system is running low on refrigerant, there is a leak. Since leaks are difficult to find and fix, you should always call a professional to find and repair it.

Breached Ductwork Holes and loose connections in your ductwork cause air leaks, losing almost a third of your HVAC system's efficiency. It forces your system to work harder to cool your home and blows around dust and debris that it pulls from the leaks.

Skipped Maintenance Skipping annual maintenance for your HVAC is a mistake. Maintenance allows a professional to catch any serious problems before they get worse and leave you miserable in the summer heat. A full inspection will ensure your system is working as effectively as possible.
