What size air conditioner do I need for my home?

Proper sizing depends on square footage, insulation levels, ceiling height, window placement, sun exposure, and ductwork design. A professional load calculation should always be performed before selecting equipment.

Is it better to repair or replace my air conditioner?

Most residential AC installations can be completed within one day, although more complex projects involving ductwork modifications, electrical upgrades, or full system replacements may require additional time.
