What is one of the main concerns when inspecting HVAC systems?

One of the main concerns when inspecting HVAC systems is the presence of water or moisture. Moisture can lead to a variety of serious issues within an HVAC system, including mold growth, corrosion, and damage to components. When water accumulates, it can trigger inefficiencies by causing the system to work harder than necessary, potentially leading to breakdowns or decreased lifespan of the equipment. Additionally, moisture can create an unhealthy indoor environment, contributing to air quality problems. Inspecting for water leaks or signs of condensation is essential for ensuring that the HVAC system operates effectively and safely.
