Common AC problems we have encountered

Are you having problems with your air conditioner? At Certified Climate Control, we offer quality HVAC repair in Orlando and nearby areas. Read below to find out more about some of the common AC problems we have encountered.

Improper Operation

The top air conditioner problem is inefficient operation. This includes leaving a window or door open while the AC unit is running, or operating an air conditioner in a room or home that has not been weatherproofed. A great deal of cool air escapes through small cracks and holes in the wall and near windows and doors, so it’s important to improve the insulation of your home before you operate your air conditioner.

Inadequate AC Maintenance

For optimal performance and efficiency, schedule an AC tune-up with your local AC service company at least once per year, which includes a thorough inspection and cleaning service. Furthermore, be sure to change the AC filter at least once per month during cooling season. If AC filters and coils become dirty, the air conditioner will not function efficiently and it will be more likely to wear out and fail prematurely.

Leaking and Drainage Problems

If your air conditioner is low on refrigerant, it probably has a leak. Unfortunately, it’s not as easy as adding refrigerant. A trained AC service technician must be called in to repair the leak, test the repair, and charge the AC unit with the proper amount of refrigerant. The efficiency and performance of your air conditioner is greatest when the refrigerant charge matches the manufacturer’s specification.

Sensor Issues

Room air conditioners come with a thermostat sensor that measures the temperature of the air entering the evaporator coil. A failing sensor causes the AC unit to behave strangely, such as cycle on and off frequently.

Electric Failure

On older or poorly maintained air conditioners, it is common for the compressor and fan controls to wear out. Wire and terminal corrosion can be a problem for many AC units, so it’s important for your AC service technicians to check electrical contacts and connections during every AC tune-up.
