Top Warning Signs You Need Professional AC Repairs


When it comes to having your home’s air conditioning system repaired, you want to act at the earliest indication something isn’t right. Otherwise, you may end up with an air conditioner that doesn’t work at all. The sooner you call our professionals for air conditioning repair in Hillsboro, OH, the sooner you can relax knowing that the AC will keep delivering comfort to your home without trouble.

Some of the warning signs from an air conditioner are clear, such as when the house won’t get cool enough no matter how you set the thermostat. Others are less obvious, and we’ve listed some of these trickier signs below. Call us to diagnose the trouble and get your air conditioning system in great shape.

Unusual noises or louder operation

An air conditioner makes a set number of sounds as it runs: the whirring of the fans, the hum of the compressor motor, the drip of condensate moisture, and the occasional clicking as it powers down. If the AC begins to make strange noises you haven’t heard before, such as rattling, hissing, bubbling, grinding, and shrieking, it’s a major red flag. Also, watch out for when the air conditioner becomes louder than before.

Uneven cooling

The center of your house feels cool when the AC is running, just the way you want it. But other rooms are warmer than expected. This uneven cooling from the air conditioner is often an early sign the system is losing its cooling capacity—it has enough power to reach part of the house, but not all of it. 


This is a frequent problem air conditioners run into. It’s when the compressor starts a cooling cycle but then shuts down prematurely. Cooling cycles should last for 15 to 20 minutes. If the cycles are shorter and the AC is turning on and off multiple times during an hour, something is interfering with its normal operation. Not only does the underlying problem need to be fixed, but short-cycling itself places tremendous strain on the AC’s components and will run up energy costs substantially. 

A spike in utility bills

An unexpected rise in energy costs is a general warning sign for many types of air conditioning problems. If your electric costs on your utility bills seem unusually high without any good reason, something is holding back the AC’s efficiency. If it isn’t a simple problem like a clogged air filter that needs to be replaced, you’ll want technicians to look into it.

Constant fiddling with the thermostat

An air conditioning system and thermostat are designed to work together so you can put the thermostat at a single comfortable temperature and leave it there for most of the day, changing it only in the cooler evening. If you’re continually adjusting the thermostat up and down to find the right comfort level when this was never an issue before, you may have a malfunctioning AC or thermostat.
