my installation won't turn on

HVAC

The answer to 'my installation won't turn on' is that there could be several common causes, such as a tripped circuit breaker, a thermostat issue, or a problem with the HVAC unit itself. Symptoms may include the system not powering on at all or not responding to the thermostat controls.

First, check the circuit breaker or fuse that powers the HVAC system. If it has tripped or blown, reset or replace it. If the issue persists, the problem could be with the thermostat, wiring, or an internal component of the HVAC unit. These issues typically require the expertise of a professional HVAC technician to diagnose and repair.

Try replacing the batteries in the thermostat or checking that it's properly connected to the HVAC system. If the thermostat still doesn't work, it may need to be replaced by a professional.

When should I call an HVAC technician?
