Thomson Heating and Air: Reliable HVAC Services Serving San Antonio, TX 78214

Short cycling is often caused by an oversized unit, a dirty air filter, or a refrigerant issue. Our technicians can diagnose the root cause, which for many San Antonio homes is an improperly sized system. We provide expert repair or, if needed, a correctly sized HVAC installation to improve efficiency and comfort.

Uneven cooling often stems from ductwork problems or an undersized system. Our comprehensive HVAC system maintenance includes checking duct integrity and airflow. For a lasting solution, we can design and install a replacement system with zoning capabilities or duct modifications to balance temperatures throughout your home.

Our preventative maintenance is designed for our local climate. We thoroughly clean coils, check refrigerant levels, calibrate thermostats, inspect electrical components, and ensure proper airflow—all key to preventing short cycling and uneven cooling. Regular maintenance keeps your system reliable and efficient through hot Texas summers.
