Our Residential Air Conditioning FAQ's
Why is my air conditioner not cooling evenly?
Uneven cooling can result from airflow issues, aging equipment, or improper system sizing. Our technicians evaluate your system and recommend adjustments, repairs, or upgrades to restore balanced comfort.
How often should my home AC be serviced?
Annual AC maintenance before summer is recommended to keep your system running efficiently and reliably. Tune-ups reduce energy use and help prevent peak-season breakdowns.
How long do residential AC systems typically last?
Most air conditioners last 10–15 years with proper maintenance. If your system is aging or inefficient, Moonlight Mechanical can recommend modern, energy-efficient replacement options.
