As the summer heat intensifies, a well-functioning air conditioning system becomes crucial for comfort. However, like any other appliance, your AC unit can encounter issues that disrupt its performance. In this blog, we’ll explore five common AC problems and offer insight on how they can be addressed.
1. Refrigerant Leaks
One of the most frequent issues with AC units is refrigerant leaks. If your system is low on refrigerant, it won’t cool your home effectively, and you might notice warm air blowing from the vents. Refrigerant leaks not only reduce efficiency but can also cause long-term damage to your system. If you suspect a leak, it’s essential to call a professional to locate and repair it, followed by a refrigerant recharge.
2. Dirty Air Filters
Air filters are critical in keeping your AC running smoothly. When filters become clogged with dust and debris, they restrict airflow, forcing the system to work harder. This can lead to reduced cooling efficiency and even cause the unit to overheat. Regularly replacing or cleaning your air filters can prevent this issue and keep your system operating at peak performance.
3. Frozen Evaporator Coils
If your AC is running but not cooling, the evaporator coils might be frozen. This can happen when there’s insufficient airflow due to dirty filters, low refrigerant levels, or blocked vents. A frozen coil prevents the AC from absorbing heat, resulting in poor cooling. If you notice ice buildup on the coils, it’s important to turn off the system and call an expert to address the underlying cause.
4. Thermostat Problems
Sometimes, the issue isn’t with the AC unit itself but with the thermostat. If your thermostat isn’t functioning correctly, it can cause your system to cycle on and off irregularly or not turn on at all. Check to ensure the thermostat is set to the correct mode and temperature. If it’s still not working, a professional inspection may be necessary to determine whether a repair or replacement is needed.
5. Clogged Drain Lines
Your AC system removes moisture from the air, which is then expelled through the drain lines. Over time, these lines can become clogged with dirt and algae, causing water to back up into the system. This can lead to water damage and even mold growth. If you notice water pooling around your unit, it’s time to have the drain lines cleaned by a professional.
