The answer to 'my emergency HVAC service keeps shutting off' is that there could be several common causes, such as a malfunctioning thermostat, a clogged air filter, or a problem with the electrical components. The symptoms may include the system turning on and off repeatedly, uneven cooling or heating, or a complete system shutdown.
Some potential solutions include replacing the air filter, checking the thermostat settings, and ensuring there are no issues with the electrical connections or circuit breakers. However, if the problem persists or you're unsure of the cause, it's best to call a professional HVAC technician to diagnose and repair the issue.
