Literature support FAQ

Common questions about manuals, registration, and support for this brand.

  • How often should I clean or replace my furnace filter?

    Your furnace filters must be cleaned at least two times a year, or more often if excessive dust is present. Keeping filters clean prevents dust from building up on internal components, which can result in loss of efficiency and equipment damage.

  • What should I do if my system's A2L leak detector suspects a refrigerant leak?

    If the leak detector detects a possible leak and prevents your system from cooling or heating, immediately call a qualified installer or servicer. The leak detector may also cause your thermostat to display a 'service needed' message.

  • Can I install my own single-package air conditioner or heat pump?

    Under no circumstances should the appliance owner attempt to install or service this equipment. Improper service can cause an explosion, electrical shock, or other hazardous conditions. Always consult a qualified installer or certified service agency.

  • What does the 'AUTO' fan setting do on my thermostat?

    Setting the thermostat fan mode to AUTO allows the outdoor fan, compressor, and indoor blower to cycle on and off automatically as needed to maintain the indoor temperature at your desired comfort level.

  • Why is there water vapor rising from my outdoor heat pump in the winter?

    This is perfectly normal during the automatic defrost cycle. When frost accumulates on the outdoor coil in cold weather, the unit temporarily heats the coil to melt the ice and snow, causing the melting frost to evaporate and rise as water vapor.
