The answer to 'how to clean installation' is that regular cleaning and maintenance of your HVAC system is essential for optimal performance and energy efficiency. As an expert HVAC technician, I recommend following these steps to clean your HVAC installation:
First, turn off power to the unit at the circuit breaker or disconnect switch. Next, remove the air filter and clean or replace it according to the manufacturer's instructions, typically every 1-3 months. Then, use a vacuum hose attachment to carefully clean the blower compartment, coils, and other accessible areas. Be sure to avoid getting any water or cleaning solutions on the electrical components. Finally, wipe down the exterior of the unit to remove any dirt or debris.
