Frequently Asked Questions

How often should I schedule HVAC maintenance?
We recommend twice a year — once in the spring for your cooling system and once in the fall for your heating system. This helps keep your equipment efficient and reliable year-round.
A typical tune-up includes cleaning coils and filters, checking refrigerant levels, inspecting electrical connections, calibrating thermostats, testing safety controls, and verifying overall system performance.
You can handle simple tasks like changing air filters regularly, but professional maintenance is important to address deeper issues, ensure safety, and keep warranties valid.
Routine maintenance improves efficiency, which lowers energy bills. It also reduces the chance of costly emergency repairs and helps your system last longer.
Our certified technicians provide detailed inspections, honest recommendations, and dependable service backed by strong warranties. We treat your home with care and keep your comfort a top priority.
