    Glossary of Terms

    Accessories: Combine any of the above air conditioning units with a Lennox Comfort Control thermostat for whole house comfort. Some controls will control heating, cooling & humidity. Some of the thermostats can be set to automatically switch between heating and cooling as needed. They can also monitor the outside temperature and adjust your furnace-mounted humidifier on the colder days to help prevent condensation on windows.
