Inspect HVAC Components

Affordability

Conducting regular inspections of all your HVAC components and keeping them in good repair is an easy, affordable way to minimize the performance degradation of the heating or cooling equipment for your building.

What you need to know

• Inspect all ductwork (including flexible connections) for air leaks. Seal leaks by taping, caulking or replacing flexible connections.
• Insulate all bare ducts that carry conditioned air and all chilled or hot water pipes.
• Inspect all dampers, blades, edge seals and linkages. Replace and adjust if necessary.
• Inspect inlet vane damper linkage for smooth operation and control of airflow.
• To ensure proper seating for minimal leakage, inspect air valves in mixing boxes.
• Repair any leaks from pipes, taps, pumps and control valves.
• Replace air filters at regular intervals or at pre-determined pressure drops.
• To prevent overheating and overcooling, adjust all variable air volume boxes so they operate precisely.
• Where applicable, install adjustable speed drives on fans, chilled water pumps and heating pumps.
• HVAC fans vary widely in efficiency. If budget allows, consider retrofitting your HVAC fan to save money.
• Check that the HVAC cabinet has maintained its integrity – otherwise it may be spilling chilled air to the outdoors and wasting money.
• When it is time to replace equipment, seek energy efficient HVAC options.
