Yes! The best way to keep your system running at peak performance by far is with regular maintenance. This allows for a trained technician to inspect, clean, and calibrate your system as well as catch issues before they cause a decrease in performance. Additionally, ensuring that your air filters are replaced or cleaned (depending on the type of filter) at the correct intervals is paramount to efficiency. You can also keep shades, blinds, and shutters closed during the summers to keep sunlight and heat out, and make sure your weather stripping and ductwork aren’t leaking or damaged.
