If you live in the U.S., you know the necessity of having a properly functioning air conditioner (AC), especially during the summer. You need to inspect your AC regularly for any issues to ensure it is ready when you need it. Knowing the signs of a malfunctioning AC will enable you to seek AC repair early on. The following are seven warning signs you need AC repair.

1. Low Airflow

Your home will have sufficient airflow if your AC is working properly. However, a broken AC will result in low airflow. Low airflow is a common sign that your AC needs repair. You can tell the air quality in your house is poor if your family exhibits fatigue symptoms, headaches, and coughs.

2. Increased Energy Bill

An AC consumes a lot of energy. According to the Department of Energy, 75% of all homes in the United States have air conditioners. Air conditioners use about 6% of all the electricity produced in the United States, at an annual cost of about $29 billion to homeowners. A malfunctioning one consumes even more energy. If you notice your electricity bills are inexplicably increasing, your AC could be the reason.

3. Old AC

The older your AC gets, the higher its chances of malfunctioning. You need AC repair if your AC is old and continually breaking down. An expert will effectively repair your AC.

4. Warm Air

If your AC is blowing warm air instead of cool air, it could be a sign that it is broken. If the problem persists even after turning your system to cooling mode, contact a qualified professional. The problem could be the system's compressor or thermostat.

5. Fluctuating Temperatures

If your AC is properly working, your home temperature should be the same throughout your house. Your AC needs repair if different rooms have different temperatures.

6. Noisy System

Your AC should run quietly. It is easy to notice if any strange sounds are coming off your AC. Look for an AC repair expert if yours is producing banging, humming, or clicking sounds.

7. Unusual Smell

A humid, stuffy smell in your home is another sign that your AC system needs repair.
