Make the Call for Comfort

Your One-Stop Shop for Everything HVAC!

It may seem silly to be thinking about your air conditioner in February, but the truth is with spring just around the corner now is the time to start thinking about getting your system ready for the long months of use that lie ahead. Before you know it, winter temperatures will give way to the warmth and heat of spring and summer, and you’ll be flipping your air conditioner on for cooling comfort at home.

Before you do, however, you’ll want to make sure your air conditioner receives its annual maintenance tune-up from our Sterling and heating and cooling team. Air conditioning maintenance is an important service for homeowners because it ensures that your air conditioner is at its most efficient and most reliable all summer long. This important step ensures you’ll see few to no major breakdowns over the course of the warm season, improved cooling performance, and even save more money on your energy costs! Plus, if your system is still under warranty, an annual maintenance service is required to keep your warranty active and ensure you remain protected against serious issues.

Here are a few of the services that you’ll receive from an A/C tune-up service, and how they help you enjoy your air conditioner to the fullest.

Coil Cleaning*

Your air conditioner relies on two metal coils which refrigerant flows through in order to cool your home: your condenser coil which is outside, and your evaporator coil, which is inside. Both of these coils can accumulate a layer of dust over time as air is passed over them. This dirt acts like a blanket, insulating these coils and preventing the heat transfer which makes your air conditioner work. Clean coils are the most efficient coils, and that’s why one of the most important parts of your tune-up service is having both your indoor and outdoor coils professionally cleaned.
*Coil Cleaning is an optional item and is priced per job.

Electrical Connection Checking

Your air conditioner depends on a number of important electrical connections in order to work properly, and those electrical connections can come loose over time. Vibration from your air conditioner working like normal, rushing airflow, and even just degrading or eroding materials can slowly cause electrical connections to potentially become faulty, and that’s why we make sure to check and tighten them all down. This can also help prevent a potential fire—when an electrical connection comes loose, it could ground itself on the metal in your air conditioner, potentially causing sparking, overheating, and even a fire if you’re not careful.

Thermostat Calibration

Have you noticed that you seemingly have to turn your air conditioner down more and more in order to be comfortable? You’re not going crazy, your thermostat simply needs calibrated. Air conditioner calibration is an important part of your maintenance service in order to make sure you have the most precise control over your heating and cooling system. This can also help you save money by ensuring that you reach your temperature goal properly, and your system doesn’t accidentally continue running beyond when you want it to stop.

Oiling Moving Parts

Your air conditioner has a number of moving parts—blower fans, belts, motors, pulleys, and much more. When these parts start to grow old, they start developing more friction, and more friction means more energy is needed to make them move. That means reduced efficiency, and more money out of your pocket in energy costs. Our air conditioning tune-up service includes lubrication for these moving parts to ensure minimal friction, smooth operation, and significantly reduced wear and tear on your system. This also drastically reduces the chances of a serious breakdown from part failure due to excess friction or overheating.
