The most important thing a homeowner can do for their HVAC system and their indoor air quality is to change the unit’s filter on a regular basis. Every home is different, but most professionals will recommend filter replacement every month or two. This ensures that no debris gets sucked through the system and that your furnace and air conditioner have adequate airflow. We also recommend getting your system maintained by a professional yearly. At Ninja Heating and Air, we perform in-depth diagnostic checkups on systems to make sure you don’t run into any unnecessary breakdowns. Being a member of our Home Health Plan provides you with a furnace tune-up in the fall and an A/C tune-up in the spring, and you don’t even have to remember because we call you!
