maintenance is important
​For a typical Arizona business, heating and cooling account for up to 50% of electricity costs. Poorly maintained equipment consumes more energy than it should and is likely to fail sooner. In some cases, lack of proper maintenance may void manufacturer warranties.

Consider hiring a contractor to perform a seasonal tune-up. There are varying levels, but the most beneficial tune-ups will include the following and can improve performance up to 10%:

  • Refrigerant charge & air flow verification
  • Belt replacement
  • Tightening of any loose electrical connections
  • Removal of dirt build up on coils and drain lines
  • Economizer function test

Additionally, you should change filters monthly. Dirty filters require the system to work harder to maintain the appropriate level of air flow.

easy ways to save
  • ​Install a smart thermostat and create a daily schedule with your optimal temperature settings.
  • Save 2-3% for every degree you raise or lower your thermostat setting depending on the season.
    • In the summer, we recommend 78-80 degrees when the building is occupied and bumping it to 85 degrees after hours.
    • In the winter, try 70-72 degrees when the building is occupied and dropping it to 65 degrees after hours.
  • Make sure vents are clear so there is proper air flow.
  • Utilize ceiling fans to more evenly distribute air and eliminate hot and cold spots. The evaporative effect can make occupants feel 3-5 degrees cooler in the summer, but make sure it isn’t running and unnecessarily using energy when the room is empty.
  • Install shade screens, window film or blinds to keep out the hot summer heat and open the blinds in the winter to take advantage of the radiant heat.
  • Encourage employees to keep windows and doors closed especially during heat waves and cold spells.
  • Add a cool control device to your existing HVAC unit. The device makes the fan run longer to utilize more of the residual cooling in the coils.
  • Install CO2 sensors so the system takes into account not just temperature preferences but air quality requirements.

​Insist on a quality install. If not properly installed, your equipment won’t perform to its advertised capacity. Here is a list of contractors who have performed work for APS customers.
thermostats & loadshifting
​When you use energy is just as important as how much you use. Whether you are trying to manage your demand charge or maximize your savings on a time-of-use plan, pay close attention to when you are running your HVAC equipment. You can shift load by pre-cooling your space before the peak hours of 3 to 8 p.m. which cuts down on your need for energy during that critical time. Smart thermostats and energy management systems simplify the scheduling process and may qualify for rebates.
​If your HVAC unit has failed or is approaching the end of its useful life, take advantage of our rebates and upgrade to a more efficient system. We can help with everything from package units to chillers. We also offer rebates for HVAC controls such as smart thermostats and energy management systems.
