Your central air conditioning unit is an invaluable and essential part of your home. It keeps the temperature in your house comfortable no matter what the weather outside may be like. Unfortunately, central air units have a limited lifespan and will eventually require repairs to keep them running optimally and safely. Knowing when to call for professional repair services can help you avoid costly damage that could leave you without cool air during the hot summer months. Here are four signs that it's time to get your AC checked out by an HVAC specialist:

1. Strange Noises

If your central air unit is making any strange noises, such as buzzing or grinding, you should have it looked at as soon as possible. These are usually signs that there's a problem with the motor or other internal components. Fixing these issues early can help save you money in the long run and prevent more damage from occurring.

2. Poor Air Flow

If you notice that the air coming out of your vents isn't as powerful as it used to be, or if there are cold and hot spots in different rooms, this could mean that the airflow is obstructed somehow. This could be a sign that the ducts need to be cleaned, or it could mean something more serious like a problem with the compressor. A professional can diagnose what's causing the air blockage and make sure your AC is running at its best.

3. High Energy Bills

If you've noticed an unusually high energy bill lately, this could indicate that your AC isn't functioning properly and needs some repairs. The motor or compressor may be operating inefficiently, or there could be a leak in the ducts. Having a professional inspect your system will help you save money by pinpointing and fixing any issues that are causing your bills to skyrocket.

4. Water Leaks

If you've noticed water pooling around the base of your AC unit, this is a sign that something needs to be fixed. This could indicate a refrigerant leak, or it could mean that the condensate drain is blocked or clogged. A professional HVAC technician can determine what's causing the problem and repair it quickly so you don't have more serious damage down the line.

Regular maintenance and repair of your central air conditioning unit are necessary to keep it running smoothly and safely. If you notice any of the signs listed above, call a professional HVAC service in your area such as Fred Williams and Sons Heating & Cooling to prevent further damage from occurring. They can diagnose the problem and provide you with the best solution for your particular system. Taking care of your AC now will help you save money in the long run and keep your family comfortable.
