Your A/C needs to be fixed again. Should you call an HVAC technician? Not yet. Before spending the time, money and other resources on repairs, you should check and make sure the problem isn’t something fairly simple that you can resolve on your own. To that effect, here are five A/C troubleshooting tips to try before calling a professional.
- Check the power. Is your A/C unit turned on and plugged in, and is power flowing to it? Check to see if the circuit breaker has been tripped, and reset it if necessary. Also check the thermostat, make sure it’s turned on and replace the batteries.
- Check the airflow. If your A/C has power, but little or no air is coming out, one of the most important A/C troubleshooting tips is to check and (if necessary) replace the air filter. Then, remove the registers from the vents and wash them with soap and water, to get rid of any clogs. Check the vents themselves for obstructions, and remove them if possible.
- Clear any debris. If there’s an airflow problem, it may be to the outside unit. Clear away any dirt, leaves, and other debris that may be impeding airflow to the condenser, preventing it from pulling in air. If there’s tall grass or other obstructions around the unit, clear it away, making sure there’s at least a square foot of room on all sides of the unit.
- Adjust the thermostat. Try turning the thermostat down about 10 degrees, to see if the sudden colder setting makes the system kick in.
- Check A/C sizing. If your system struggles and works overtime to keep your house cool, or if it cycles on and off frequently, causing disparate temperatures between rooms, then you might have the wrong size A/C for your home. If you just added an extra room to your house, the old A/C likely isn’t big enough to accommodate the additional area. Have an HVAC contractor size your home for a replacement A/C that fits your cooling needs.
