Maintenance and Cleaning

Develop a “big” picture for your heating and cooling. Turn it off or turn it down when the building is unoccupied. Select energy-efficient temperature set points and set all fans to “auto” instead of “on.”


Proactive equipment maintenance and repair is one of the most powerful assets in your energy-saving toolbox. Consistent monitoring and repair reduces energy costs and extends the life span of your heating and cooling equipment.

  • Replace filters frequently to ensure smooth airflow.
  • Repair faulty or outdated controls that don’t operate equipment at optimum levels. 
  • Check to see if all valves are in good working order.
  • Repair piping or duct leaks to prevent thermal loss or unnecessary pumping
  • Fill in insulation gaps to reduce unwanted temperature transfers.


Dirt in motors, fans, and pumps increases friction, obstructs flow paths, and puts an added energy drain on your equipment. Regular cleaning increases equipment productivity and reduces energy usage.

  • Clean pipes to remove sediment buildup.
  • Remove dust and debris from air ducts. 
  • Clear debris from heat-transfer coils and straighten bent coils.


Upgrading your HVAC system should be the last step in improving overall energy efficiency, because improvements in other areas may reduce the size of system required.

Sizing is critical. If your site is large or architecturally unique, insist that your contractor complete a sizing worksheet or run a computerized sizing analysis.

Don’t buy an oversized HVAC on the theory that more capacity is better.

Oversized HVAC equipment increases your load usage without providing any measurable benefit to your structure. Installing the correct size HVAC will allow you to heat or cool your building efficiently.
