Air conditioners often give indications of a problem long before they fail outright. Now is a good time to think back on summer and whether there were any signs. You may not need your AC just yet, but you will again soon. A proactive repair can help you avoid getting no cool air when you need it.
Rising Electricity Consumption
Even a small malfunction can disrupt an air conditioner and cause it to use much more electricity. It’s why HVAC experts encourage homeowners to monitor energy consumption month to month and year to year. Was your cooling bill higher than it’s been in the past? If so, schedule a service appointment. Many electricity providers will let you sign up for energy spike alerts. You can also invest in a smart thermostat with energy monitoring. Both of these approaches can make you aware of excess usage in hours or days rather than weeks or months.
Short Cycling
Cycle times vary depending on the system and the home, so you need to become familiar with yours. A typical cycle time is 10 to 15 minutes, and a typical cycle frequency is two to three times an hour. A common sign you need AC repair is a unit that turns on and off more frequently than that. Often, the cause is as simple as a clogged HVAC filter. Still, frequent cycling can cause significant wear and tear. There can be more serious causes, too, including a refrigerant leak or an overheating system.
High Humidity
Dehumidification is a byproduct of air conditioning, but an AC isn’t a dehumidifier. That means that on really humid days, your home may be less comfortable than normal. If you notice your home becoming more humid on a regular basis, that’s a problem. It often suggests a malfunction with the evaporator coil or some other aspect of the refrigerant system.
Musty Smell When the AC Cycles On
Don’t ignore a musty smell when the air conditioner kicks on, even if it’s fleeting. It could mean that there’s microbial growth on the evaporator coil. That growth can affect your indoor air quality and even make you sick. There might also be mildew or mold in the ducts. That usually means there’s moisture in the ducts, and the problem will worsen.
Loud or Unusual Noises
If you hear a loud bang or pop when the outdoor condenser unit cycles on, there’s a problem. The AC is hard starting, which usually reflects a serious issue with the compressor. Inside, listen for grinding and rumbling noises. Grinding often indicates a blower issue. Rumbling may mean damaged ductwork.
