As the temperatures rise, one thing that you don't want to have to deal with is an air conditioner that doesn't work properly. The good news is that you – the homeowner – can often fix your own air conditioner with a little bit of know-how. Here are a few common scenarios that you may run into with your air conditioner and what you need to do.
Your Air Conditioner Won't Come On
- Check the Circuit Breaker – Make sure that there is indeed power to your air conditioner by ensuring that the circuit breaker hasn't tripped. If it has, flip it back on.
- Check the Thermostat – Believe it or not, your thermostat may have gotten flipped to the "off" or "heat" position by accident, so make sure that it is set to "cool". Also, check to ensure that the temperature is set at a temperature below the room's current temperature.
- Check the Filter – If the filter is dirty, the air conditioner won't operate efficiently. In some cases, it won't even come on. Slide the filter out completely and make sure that it is clean. If it is clogged with dirt and debris, change it out with a new one.
- Check the Condenser – The condenser is the outside unit and should be inspected if your air conditioner is still not coming on. Over the summer, if grass and weeds are not kept under control around the condenser, it can cause it to not function properly. Make sure to remove any obstructions and make certain that there is nothing else within a few feet of the unit.
The A/C Comes On, But the Air Isn't Cool
- Check all of the above – Apart from the breaker, as these can impact the ability of the A/C unit cooling your home properly.
- Inspect the Ducting – Look for any signs of damage or disconnections in the ductwork, such as holes, crimps, or cracks. Any repairs should be made with mastic tape (made for ducting).
Your Air Conditioner Is On, But It's Muggy
- Inspect the Registers – Move throughout your entire home and check to make sure that your registers are not currently blocked by window treatments, furniture, or any other object.
- Check the Windows – If you have your air conditioner on, your windows should be completely closed. If you have storm windows, close them to ensure that any warm air is kept out.
