-
How often should a ductless mini-split system be serviced?
We recommend a twice-a-year maintenance schedule to ensure your system runs efficiently. These tune-ups can extend the life span of your system and allow our technicians to catch and fix minor problems before they become major issues.
-
When should I schedule ductless mini-split maintenance?
We recommend annual maintenance just before peak operating season. If you’re using your ductless mini-split for cooling, schedule a tune-up in the spring. Schedule maintenance mid-fall if you use your system for heating.
-
How long should my ductless mini-split system last?
If your system gets regular quality maintenance, it could last as long as 15 to 20 years, though multiple factors, such as usage frequency, will affect your specific system’s lifespan.
-
How often should I change my air filters?
It depends on the filter and other factors, including whether you have pets in the home, smoke, leave windows open during the day, etc. Some filters will fill up within a month, while others may take three months. Because every home is different, we recommend checking your filters every month until you establish the ideal frequency for your home.
-
Do air scrubbers eliminate odor?
The UV light in an air scrubber can break down odor-causing particles from cooking, smoke, household garbage, and more. This will leave your home smelling cleaner and fresher.
