Ninety percent of American homes use some form of air conditioner, whether it’s central heat and air or window units. These essential systems help keep American homes cool and comfortable when the weather gets hot.

Unfortunately, air conditioning systems don’t last forever. The average system will last between twelve and seventeen years under normal conditions. During this lifespan, a few common air conditioner problems could arise.

What are the most common AC issues? What may be the root cause of these problems? Below are the answers to these questions.

Air Conditioner Is Running Constantly

There may be an issue with the thermostat, condenser, air filters, or even the electrical components of the unit

While the air conditioner will run more when the weather gets hotter, it should never run constantly. It should complete an entire cycle and turn off once the house has reached the temperature user has set the thermostat for.

Several different problems could cause a constantly running air conditioner. There may be an issue with the thermostat, condenser, air filters, or even the electrical components of the unit.

The AC Won’t Turn on

If the Indianapolis air conditioner doesn’t turn on at all, try turning down the thermostat. If the AC still doesn’t kick on, the issue may be a tripped circuit breaker, which is an easy fix. On the other hand, it could also be a faulty thermostat or loose wiring, which requires professional assistance.

AC Is Blowing Hot Air Instead of Cold

If the AC is blowing hot air instead of cold, many issues could be to blame. The air filter could simply be dirty, or there may be an obstruction somewhere in the ducts. Debris could be causing the unit’s compressor to overheat, or refrigerant levels could be below.

The Unit Is Short Cycling

If the unit is short cycling, the user should turn it off and call a technician

Short cycling means the air conditioning system is turning on and off quickly, without finishing a complete cycle. This is a serious issue that could cause damage to your unit’s compressor. So, if the unit is short cycling, the user should turn it off and call a technician in Indianapolis as soon as possible.

Short cycling has a few potential causes. The air filters could be clogged, or the thermostats might need to be calibrated. If the air conditioner is new, it may be too powerful for the home.

When the air conditioner isn’t running the way it’s supposed to, it can be frustrating. The four issues above are the most common, but they’re far from the only ones. Only an HVAC technician can help to find and fix air conditioner issues.
