frequently asked questions

Most systems should be serviced twice a year—once in spring for cooling and once in fall for heating—to ensure optimal performance and prevent costly breakdowns.

Warning signs include weak airflow, unusual noises, warm air from vents, leaks, or rising utility bills. Addressing these early prevents bigger problems.

The correct size depends on your property’s square footage, insulation, and layout. Professional load calculations ensure efficiency and proper comfort levels.

With regular maintenance, most systems last 12–15 years. Ductless and mini-split systems may last longer with proper care.

Yes, ductless systems are highly efficient since they eliminate energy loss through ductwork and allow zone-specific heating and cooling.

Maintenance typically includes cleaning coils, inspecting filters, checking refrigerant, tightening electrical connections, lubricating parts, and testing system efficiency.

Yes, but replacing both together is often more efficient and ensures balanced performance since both units are designed to work as a system.

Schedule regular tune-ups, change filters monthly, seal ductwork, and consider upgrading to energy-efficient systems for long-term savings.
