Holleman's Heating & Air | Reliable HVAC Services in Snellville, GA

First, check your thermostat is set to 'Cool' and the temperature is set lower than the room reading. Next, ensure the circuit breaker for the outdoor unit hasn't tripped. Finally, check and replace your air filter if it's dirty, as restricted airflow is a common cause of poor cooling. If these steps don't help, call us immediately to prevent further strain on the system.

The main sign is your system getting 'stuck' in one mode. You might have heat blowing when set to cool, or cool air when set to heat. You may also hear a hissing noise from the outdoor unit. Since the reversing valve switches the system between heating and cooling, a failure leaves you without the proper function for the season. We recommend a professional diagnosis to confirm and repair it.

We prioritize emergency calls, especially during extreme weather. For urgent situations like no cooling in a heat wave or no heat in winter, we aim for same-day service. When you call, we'll gather details to dispatch the right technician and parts to resolve your issue as quickly and completely as possible.
