FAQs

FAQs

It’s recommended to schedule AC maintenance at least once every year, preferably in early spring. This helps ensure your cooling system will be well-prepared for the summer heat.

Ideally, air filters should be changed every 90 days. Dust particles, hair, pet dander, and other debris can circulate through your home’s air and accumulate on your AC filter. Changing filters periodically helps improve both air quality and performance.

Most air conditioners are designed to last between 10 and 15 years. If your system has reached its peak age and you notice signs of decline, you may want to consider replacement.

Some common AC repairs include cleaning and replacing the air filter, replacing parts, and repairing refrigerant leaks.

It’s generally not recommended to cover your air conditioner in the winter, as covers can trap moisture and damage your system.
