Expert Troubleshooting & AC Repair
A malfunctioning air conditioner makes the house uncomfortable and increases your home cooling costs. Usually, the air conditioning system will show signs of trouble before it completely breaks down. Calling for AC repair in Frankfort when you first notice the system isn’t running quite as well as normal can prevent a larger and more expensive problem.
Some common AC problems include:
- The system not turning on
- Warm air coming from the vents
- Water leaks
- Reduced airflow
- Inconsistent temperatures
- Low refrigerant
- The room temperature does not match the thermostat
- Higher than normal utility bills
Accurately diagnosing the problem is the most important first step in restoring your home's comfort. Air conditioning systems can be complex and pinpointing the problem requires the right tools and expertise. Let an experienced HVAC technician inspect your system to make sure the problem is accurately diagnosed and properly repaired.
It is common for homeowners to put off calling for AC repair for problems that seem minor like higher utility bills or inconsistent temperatures from room to room. This is a mistake because waiting to address a problem causes additional strain on the system. It’s always best to call for AC repair whenever you notice a change in performance, efficiency, or home comfort.
Waiting to call for repairs can cause bigger problems, such as:
- Additional strain on the system
- A more complex and expensive repair
