Air Conditioning FAQs
How often should I have my air conditioner serviced?
You should schedule preventative maintenance for your air conditioning system at least once a year, ideally in the spring before the intense summer heat arrives in Southern California.
Why is my air conditioner running but not cooling the house?
This common issue is often caused by a dirty air filter blocking airflow, low refrigerant levels due to a leak, or a malfunctioning compressor. Our technicians can perform a rapid diagnostic to pinpoint the exact failure.
How do I know what size air conditioner my home needs?
System sizing is based on a calculation that includes your home's square footage, ceiling height, insulation quality, and window placement. We perform professional load calculations to ensure your new unit is perfectly sized for maximum efficiency.
Is it normal for my AC to turn on and off constantly?
No, rapid cycling is a sign of a problem. It could indicate an oversized unit, a failing thermostat, or a restricted airflow issue that causes the system to overheat and shut down prematurely.
What does SEER mean when buying a new AC unit?
SEER stands for Seasonal Energy Efficiency Ratio. It measures how efficiently an air conditioner operates over a typical cooling season. A higher SEER rating indicates better energy efficiency and lower monthly utility costs.
Do you pull permits for new air conditioning installations?
Yes. Thermo Cooling Inc is a fully licensed contractor (License #1135530), and we ensure all required city permits are pulled and installations meet strict California building codes.
