United Air Conditioning And Heating - Las Vegas's Experienced HVAC Services

This is often due to a thermostat calibration issue or a frozen evaporator coil. An incorrectly calibrated thermostat misreads your home's temperature, while a frozen coil blocks airflow. Our technicians can recalibrate your thermostat for accurate control and diagnose the root cause of the freeze-up, typically low refrigerant or airflow problems, to restore efficient cooling.

In our dry climate, freeze-ups are commonly caused by restricted airflow from a dirty air filter or blocked vents, or by low refrigerant levels. Both prevent the coil from absorbing heat properly, causing condensation to freeze. We recommend regular filter changes and can perform a system check to identify and fix refrigerant leaks or other issues.

Signs include rooms feeling significantly warmer or cooler than the thermostat setting, the system short-cycling (turning on and off frequently), or unexplained spikes in your energy bill. Our experts can test your thermostat's accuracy against a precise meter and recalibrate it to ensure it correctly controls your HVAC system for consistent comfort and efficiency.
