We hope your cooling system has been running well this season. But if you’re not feeling the cool air you expect, something is likely wrong. It could be a minor fix or a major malfunction. Either way, our AC technicians can diagnose and resolve the issue.
Here’s a look at the most common culprits.
Clogged Air Filter
A dirty air filter is one of the most common reasons an AC underperforms. The filter protects your system’s internal components from dust and debris. When it gets too clogged, airflow is restricted and your system can’t cool effectively. Check your filter and replace it if needed. During periods of regular use, plan to change it every one to three months. In some cases, a fresh filter is all it takes to restore proper airflow.
Heat Pump Set to the Wrong Mode
If you have a heat pump, check that your thermostat is set to cooling mode. A household member may have accidentally switched it to heating. It’s also possible the reversing valve that switches between modes has failed, though you would likely have noticed that issue sooner.
Refrigerant Leak
An AC system should only need to be charged with refrigerant once, at installation. However, corrosion along the refrigerant lines or coils can cause leaks over time, reducing cooling power. This requires professional attention. A technician will locate and seal the leak, then recharge the refrigerant. Left unaddressed, a refrigerant leak can cause the compressor to fail, leaving you without a functioning system.
Duct Leakage
Damaged ductwork won’t cause an immediate breakdown, but it can account for up to 30% of air loss, sending conditioned air into your attic or crawlspace instead of your living areas. It also causes your system to work harder than necessary, shortening its lifespan over time.
