Q: I have an old mercury-type thermostat. Does it have to be changed when I replace my furnace?
A: It is recommended that you replace a mercury-type thermostat, but it is possible that it may control your new system. Those thermostats are not as accurate as a digital thermostat.
Q: Do they still make mercury-type thermostats? How do I dispose of my current one?
A: No, mercury thermostats are no longer manufactured. Contact your local HVAC dealer or Environmental Protective Agency for disposal information.
Q: I just need an inexpensive thermostat during my remodel. Is this still possible?
A: Yes. There are numerous thermostats available. Most use a bi-metal mechanism instead of mercury and can be obtained at most do-it-yourself stores.
Q: I'm an older person and find my new thermostat confusing to use and program. Where can I go for assistance?
A: The manufacturer's instructions, installing company, thermostat dealer, or the Internet are all good references.
Q: Are there thermostats with larger numbers that are easy to read?
A: Yes. There are several brands that are made with a large display.
