Aside from the benefit of cost savings and energy efficiency, a functional AC system can deliver better performance in cooling your home when the temperature rises. To keep your home comfortable when you need it the most, it’s crucial to watch out for the 7 signs that you need air conditioner repair. Of course, the last thing you want on a hot day is finding your AC not working properly, but as soon as you get the necessary repairs done, the sooner your home can be comfortable again.
7 Signs That You Need Air Conditioner Repair
1. Your AC is Making Weird Noises
After completing a cooling cycle, your AC may make a series of clicking sounds. This is normal. Repetitive clicking, however, is a sign that your AC may need repair.
A buzzing/humming sound could possibly indicate loose or worn parts, refrigerant leaks, broken isolation feet, a faulty circuit breaker or electrical problems.
2. It Smells Unpleasant
Does your AC smell musty? It’s probably due to bacterial growth build-up in the drain line or in the pan of your air conditioner. The evaporator coil is also dark and humid, so it’s an ideal place for mold and mildew to thrive.
When dead rodents and insects get stuck in your ductwork, it will also smell unpleasant. If gas leaks and gets into the ductwork, you’ll notice how your air smells like rotten eggs.
If you smell raw sewage, it may come from a ruptured pipe. It indicates a backed-up sewer line that needs to be checked immediately.
3. It’s Blowing Warm Air
If you notice your AC blowing warm air, check the thermostat first to ensure it’s switched to cooling mode. If your AC is still blowing warm air, it might be due to restricted airflow or issues with the compressor. It could also be a sign that it’s low on refrigerant.
4. Humidity is High
If your home feels muggy, there may be too many people inside, causing the system to not keep up or your AC may be low on refrigerant. Also, when any part of your AC is disrupted, it can cause your unit to underperform and fail to dehumidify as it’s supposed to.
5. It’s Leaking Water
Pooled water or an active leak indicates your system isn’t properly running. It’s commonly due to improper installation, low refrigerant level, damaged condensate pump, blocked air filters, or a clogged condensate drain.
6. Poor Airflow
If you notice that your AC’s airflow has gone from strong to weak, it’s more likely due to a clogged air filter. Several things can also result in poor airflow: frozen evaporator coils, blower issues, and leaky or blocked air ducts.
You may replace your air filter, as needed, but if this doesn’t improve your AC’s air flow, you may have it checked for any leaks.
7. It’s Short-Cycling
Your AC shouldn’t constantly cycle on and off, but it occurs when you have clogged air filters, miscalibrated thermostats, or low refrigerant levels. If your unit is not sized properly for your home, it may cause problems, too.
When your unit is short-cycling, it may damage your unit in the long run and cause a spike in your energy bills.
