Temperatures are high, but these techniques will help you keep your energy costs low:
- Reduce HVAC System Operations When Building or Space is Unoccupied
- Minimize direct cooling of unoccupied areas by turning off fan coil units and unit heaters, and by closing the vent or supply air diffuser
- Turn fans off
- Install system controls to reduce cooling/heating of unoccupied space
- Minimize Exhaust and Make-Up Air
- Keep doors closed when air conditioning is running
- Properly insulate walls and ceilings
- install thermal windows to minimize cooling and heating loss
- Implement a Regular Maintenance Plan
- Check fans for lint, dirt, or other causes of reduced flow
- Schedule HVAC tune-ups (with us!) – the typical energy savings generated by tune-ups is 10%
- Replace air filters regularly
- Upgrade Fuel-Burning Equipment
- Install turbulators to improve heat transfer efficiency in older fire tube boilers
- Install automatic combustion control systems to monitor the combustion of exit gases and adjust the intake air for large boilers
- Install electric ignitions instead of prior lights
- Evaluate Boiler Operations
- Investigate preheating boiler feed water
- Adjust boilers and air conditioner controls so that boilers do not fire and compressors do not start at the same time but satisfy demand
- Use hot water from boiler condensate to preheat air
