3 Common Air Conditioner Problems

by Amelia Martin

When your air conditioner isn't working, you want solutions fast. Spending even a day without air conditioning can be extremely uncomfortable in certain climates. Your AC problems might be caused by one of these underlying issues:

1. Dirty air filters.

A dirty air filter is one of the most common causes of poor AC performance. Fortunately, it's also one of the easiest and most inexpensive problems to fix. You can replace your air filter yourself by pulling it out of its housing. An air filter that needs to be replaced will look dirty. Some newer models of air conditioners even let you know when it's time to replace the filter using a light. Simply throw away the dirty filter and replace it with a new one.

2. Leaking refrigerant.

Your air conditioner uses refrigerant to cool air before circulating it throughout your room. If there is insufficient refrigerant present, your air conditioner's fan will still circulate air, but it will not feel cool. Your AC's refrigerant circulates in a closed system, so it shouldn't evaporate or run low under normal conditions. If your AC is running out of refrigerant, there is probably a leak or puncture somewhere inside your unit. A leak can be caused by damage from rodents or other pests. An AC repair serviceman can patch any leaks and replace the missing refrigerant.

3. Malfunctioning thermostat.

Window air conditioners don't require an external thermostat, but central air conditioning is usually controlled by one or more thermostats placed throughout the house. If your air conditioner won't turn on, your thermostat may be to blame. If your thermostat isn't connected to your house's electrical wiring, it probably runs on battery power. Try opening it up and replacing the battery to see if this solves the problem. If your air conditioner still won't turn on, you should call an AC repair service. There may be an underlying problem with your electrical wiring, and AC repair professionals are also equipped to solve electrical problems.
