No matter what type of air conditioning you get, maintenance is critical to keep your air conditioning running smoothly. How much you’ll need to do depends on your system. At the very least, you’ll need to change the air filter regularly as per the manufacturer’s recommendations. It’s a simple task yet an essential one. It prevents dust and other particulate matter from getting inside the unit and gumming up the works. It can also prevent allergens like spores and pollen from getting indoors with the airflow. We also recommend an annual inspection of the system in the spring or biannual with a fall visit if it is an HVAC unit. A technician can give it a thorough once-over to clean the components and check for any possible issues. It’s a small price to pay to prevent costly repairs down the road.
