Frequently Asked Questions

Filters should be changed every three months to keep your system running efficiently, prevent dust and debris buildup, maintain healthy indoor air quality, and reduce unnecessary strain that can lead to breakdowns or higher energy bills.
It's recommended to schedule HVAC maintenance at least twice a year, ideally before the start of the heating or cooling season. Regular maintenance helps improve efficiency, prevent breakdowns, and prolong the lifespan of your system.
HVAC systems typically last about 10–12 years because their components naturally wear down over time from constant use, exposure to temperature changes, and regular mechanical stress, even with proper maintenance.
Improving your HVAC system’s energy efficiency starts with regular maintenance, clean filters, and proper airflow. Upgrading to a programmable thermostat, sealing ductwork, and ensuring your home is well-insulated also help reduce energy use. In many cases, replacing older equipment with a modern high-efficiency system can significantly lower your monthly utility bills.
A technician will clean and inspect the unit's key components, check refrigerant levels, and test electrical connections to ensure the system runs efficiently and safely. This includes cleaning the coils, changing the air filter, lubricating moving parts, and checking the thermostat and condensate drain to prevent potential issues and breakdowns.
