Thermostat FAQS
Does my HVAC system support any type of thermostat?
Most modern HVAC systems are compatible with a wide range of thermostats. However, the type of thermostat your system can support depends on the wiring and the specific features of your HVAC unit. It’s essential to check your HVAC system’s specifications or consult with a professional before purchasing a new thermostat.
What's the difference between a programmable and smart thermostat?
Both programmable and smart thermostats offer energy-saving benefits, but they differ in features and capabilities:
- Programmable Thermostat: Allows you to set temperature schedules based on your daily or weekly routines. It’s ideal for those who have a consistent schedule and want to save energy when they’re not at home.
- Smart Thermostat: Offers more advanced features, including the ability to learn your habits, remote control via smartphone apps, and integration with other smart home devices. If you’re looking for more control, convenience, and potential energy savings, a smart thermostat might be the better choice.
How do I know if my thermostat is broken?
Some common signs that your thermostat might be malfunctioning include:
- The HVAC system doesn’t start or shut off when it should.
- The temperature reading on the thermostat doesn’t match the room’s actual temperature.
- The thermostat doesn’t respond to changes in settings.
- Frequent short-cycling of your HVAC system.
If you notice any of these issues, it might be time to replace or repair your thermostat.
