Common AC Problems in Katy, TX Homes
Many Katy residents experience frequent AC issues related to the intense Texas heat and humidity, which can strain any cooling system. Understanding these common problems can help you identify when professional AC service is needed:

- Strange noises: Rattling, grinding, or buzzing often signal mechanical issues requiring immediate attention.
- Water leaks: Excess condensation or blocked drain lines can cause water damage if not addressed.
- High energy bills: Inefficient systems, dirty components, or aging equipment increase electricity consumption.
- Poor air quality: Dust accumulation and mold growth inside the system reduce indoor air quality and create health risks.
