The summer is here which means your HVAC system is working at maximum capacity to keep you and your family cool. It is typical to experience air conditioning troubles while your system is working hard, so our team at Healthy Home Heating & Air has provided you with three of the MOST common problems and their solutions. Continue reading if you are experiencing an A/C issue to see if it is one of these problems and find out how to mitigate it.

Problem 1: Warm Air Flow

This common issue can present itself in two different ways: you may hear your system running but lacking airflow or you may feel air flow, but the air is warm. This can be due to a few culprits, such as your system may have a worn blower belt, low refrigerant levels, or a dirty filter.


If your system is making a screeching or squealing noise accompanied by warm airflow, it can be due to a worn-out blower belt. This can be easily taken care of by having a technician replace the belt. Low refrigerant levels can also cause your system to blow warm air. You can easily check this by placing your hand near a vent in your home to determine the temperature. A trained professional can solve this by topping off your system’s freon levels. Lastly, a dirty filter will obstruct airflow in your ductwork, leading to your compressor overheating. It is crucial to replace your filters every 30 to 90 days to prevent this.

Problem 2: Your HVAC system trips your breaker repeatedly

It will be obvious if your A/C unit continuously trips a breaker because your unit will shut off. Not only can this be frustrating and disrupt your daily comfort, but it can also be difficult to identify the cause when you are unfamiliar with your breaker panel.


Check your circuit breaker panel and identify your A/C breaker to ensure whether it has been tripped or not. An air conditioner typically trips a breaker because it is pulling in more amps than the breaker is intended for. This preventive measure protects you and your home from an overcurrent, which can lead to equipment damage and fires. When you inspect your circuit breaker panel, you can flip the tripped breaker back. However, this may be a sign that your unit is the incorrect size for your home. Our team would be happy to take a look at your unit and assess the situation.

Problem 3: Unusual Noises

It should be cause for concern if you begin to notice strange noises every time your system kicks on. This could sound like vibrating, squealing, screeching, humming, buzzing, or grinding noises.


Your HVAC system may make a variety of noises which can all be due to a different factor. This can be due to a loose component, dirty condenser coils, malfunctioning thermostat, excess moisture present, or a ductwork leak. All of which need to be addressed by a professional.
