You rely on your cooling system to keep you comfortable and safe all summer long. There are many common AC issues that can affect your comfort and even deprive you of cooling altogether. Let’s explore the most prevalent problems and what you can do about them.
High Electricity Bills
Modern air conditioning systems are highly efficient, but even minor issues can disrupt that efficiency substantially. A spike in your electric bill is often the earliest sign of an AC problem. The industry encourages homeowners to monitor their energy bills month to month and year to year. You can do it manually or buy a smart thermostat that does it for you. In either case, if you notice a spike in usage, you know to schedule an HVAC inspection.
Power-Related Issues
You may experience an AC system that won’t turn on. Rule out a power outage. If that isn’t the problem, check the system’s circuit breaker. If it’s tripped, you can reset it. If it trips again, don’t continue resetting as it suggests a serious electrical issue. If it’s not the circuit breaker, check the outdoor disconnect switch. Ensure it’s intact and seated firmly. Note that there are some non-power-related issues that can cause an AC not to turn on. Those include a clogged drain line, a clogged filter, and a major refrigerant leak.
Clogged Drain Lines
Cooling systems create condensation as a byproduct of the refrigeration process. The condensation drips from the evaporator coil into a drip pan. It then exits the home via a drainage pipe or tube. Drainage systems can clog over time due to dirt and microbial growth. If that happens, the pan will fill up, and the wet switch will trip the system as a protective measure. You’ll need a technician to come out and clear the drain line.
Weak Airflow or Uneven Cooling
Weak airflow is a common problem that causes uneven cooling distribution. You may notice warm spots throughout your home and a sharp temperature difference between floors. This may indicate the blower isn’t operating at the necessary speed. It may suggest a refrigerant leak. It can also be duct-related issues, such as leakage and dust accumulation.
High Humidity
Air conditioners aren’t dehumidifiers, but they dehumidify as a byproduct of cooling the home. Generally, ACs provide enough dehumidification for a home to be comfortable. If the home is cool but muggy, it may be very humid out or there could be an AC problem. Depending on the climate, installing a dehumidifier would make the home more comfortable. If it’s a systemic problem, likely causes include a clogged filter or a dirty evaporator coil.
Mustiness or Other Unpleasant Smells
If you notice a fleeting mustiness when the AC cycles on, it likely indicates microbial growth on the evaporator coil. You’ll need a technician to clean it with a coil cleaner. If you notice more persistent mustiness, it may indicate a moisture problem and mildew or mold in your ducts. If you notice staleness or sour smells, it likely reflects dust in your ducts.
Irregular Cycling
Central ACs and heat pumps cycle on and off. The typical cycle is 10-15 minutes and should occur two to three times an hour. An AC that runs for an extended period is long cycling. This often indicates a thermostat malfunction or improper thermostat settings. Short cycling may indicate something as simple as a clogged filter or as serious as a refrigerant leak. In either case, irregular cycling can cause excessive wear and tear to your system.
Clogged HVAC Filters
The average household has to replace their HVAC filter every three months. That said, it’s not unusual to need more frequent replacements in summer. Check your filter at least once a month, and replace it as needed. Also, check your filter’s MERV rating, and ensure you’re not using a higher rating than your AC supports.
Unusual Noises
Modern ACs are relatively quiet, and if you suddenly start hearing louder sounds, it usually means there’s a problem. A clogged filter can cause a whistling sound. Blower problems can cause screeching or grinding. Compressor issues can cause a loud bang outside when the system cycles on.
