If you have an older air conditioner, you may need AC repair this summer–especially if your system hasn’t been maintained with professional annual tune-ups. Before calling for HVAC service, try these troubleshooting tips for some of the most common solutions to air conditioning problems.
Problem: AC won’t turn on.
- Make sure the thermostat is set to the cooling mode.
- Turn down your thermostat by 5 degrees and wait a few minutes to see if it kicks on.
- Make sure the circuit breaker hasn’t tripped.
- Check the condensate tray for proper drainage. If it’s clogged, your air conditioner may automatically turn off.
- Make sure the air handler compartment is tightly closed.
Problem: Poor air supply from the registers.
- Replace your air filter if it’s dirty. A full air filter will reduce the airflow to and from your system, and is one of the most common causes for the need for AC repair
- Check your ductwork and seal loose joints and cracks, a common culprit for air leaks.
- Remove furniture and window treatments from in front of your supply and return registers to ensure proper air flow to your system.
Problem: Frequent cycling on and off.
- Make sure your thermostat isn’t obstructed.
- Spray down the outdoor condensing unit with a hose to wash away dirt and grass clippings from the metal fins. Don’t allow plants to grow close to your unit.
- Replace your air filter if it’s dirty.
Problem: AC runs but won’t cool.
- Make sure your thermostat is set to cooling and the fan is set to auto.
- Turn down the thermostat by five degrees and wait a few minutes.
- Hose down the outdoor unit to remove debris from the fins.
Prevention is the key to ensuring you won’t need AC repair this summer. Start with a professional tune-up. A qualified HVAC technician will tighten belts and connections, check the system’s airflow, refrigerant and controls, in addition to other essential tasks.
Over the course of the cooling season, keep your air conditioner in top working order and avoid costly AC repair by performing these tasks:
- Change your air filter when it’s dirty. Most air filters need replacing every one to three months. A dirty filter greatly reduces your system’s efficiency and can cause expensive damage due to poor airflow.
- Keep obstructions away from your return and supply ducts.
- Vacuum the area around your indoor unit monthly to remove dust, which can build up inside the system.
- Hose down your outdoor condensing unit every month to ensure optimum airflow.
