As the temperatures rise in Southern Michigan, so does our AC usage. And increasing your AC usage should also come with a higher incentive to maintain it. One of the most important HVAC maintenance practices to take is identifying when your AC needs repairs. Although we dread the day our AC breaks down, it is important not to ignore the signs.
1. AC Blowing Warm or Little Air
An obvious sign of a malfunctioning AC unit is when it starts to operate better as a heater than a cooler. When an AC starts to blow warm air, it’s usually caused by low refrigerant levels or problems with the outdoor unit.
Besides temperature, your AC can also struggle to blow air entirely. Little air coming from your cooling can be the result of a clogged fan, broken motor, or detached belt. If your AC is blowing warm or little air, you may need to schedule a repair.
2. Incorrect Thermostat Readings
Failing AC units aren’t the best communicators, especially when it comes to working with your thermostat. If you set your thermostat to a certain temperature and your AC takes considerable time to reach that setting or doesn’t reach it at all, it may require a repair.
However, incorrect thermostat readings are a more ambiguous sign, as this can also be caused by problems with the thermostat itself. You’ll still want to contact Iceberg Heating & Cooling for further assessment.
3. Strange Buzzing Noises Coming from AC
It’s normal for your AC to make some sound when powering up or shifting temperatures. But when there’s a loud, constant buzzing noise, it’s probably time to schedule repairs. Having a buzzing noise coming from your AC can be the result of a malfunctioning compressor, missing isolation feet, or lose connections. This can also mean your AC unit has become frozen.
4. Outdoor AC Unit Visibly Damaged
Most central AC systems are equipped with an outdoor unit that is placed on the side of a home. And although these units are designed to handle most weather conditions, problems can still ensue.
It’s important you check your outdoor AC unit for damages regularly, even if your cooling is working fine. Issues present in your outdoor unit will exacerbate, as weather conditions and strong winds can both worsen the initial problem. Notify a professional if your outdoor unit has any of these damages below:
- Rusted or Corroded Metal
- Cracked or Loose Fan
- Missing Fan Guard
- Frayed or Exposed Internal Wiring
- Invasive Tree Roots inside Unit
5. Unusually High Electric Bill
Sometimes, the easiest way to tell your AC is broken is by simply looking at the utility bill. Issues with your AC can negatively affect its performance, possibly causing it to overwork and consume more energy. And with your HVAC system accounting for almost half of your home’s energy consumption, a broken AC can make a noticeable impact on your utility bill.
