Now that you’ve had a glimpse at some of the best thermostats that money can buy, have you decided on which one best suits your needs? Before making that purchase, here are some factors that you should bear in mind before purchasing a smart thermostat.

How To Choose The Right Smart Thermostat

1. C-wire

While almost all thermostats have a battery of their own, at times, that isn’t enough juice to run the system. They depend upon the power from your HVAC system. For this, a C-wire is required. While many thermostats do not come with this, it is better to have one installed.

2. Compatibility

This is a major consideration when choosing your thermostat. Having one that is compatible with many heating and cooling devices is highly desirable. Your worst nightmare would be to purchase a thermostat that doesn’t even support your furnace and air conditioner.

3. Programmable

It is important to note that not all thermostats are programmable. A programmable thermostat is one that can control temperature settings according to a predefined schedule. It is highly recommended to purchase a programmable thermostat.

4. Connetivity and remote access

Most thermostat systems connect through Wi-Fi. An important consideration is whether or not the thermostat of your choice is controllable through an app when you aren’t physically present at home. This is crucial as it could be the determining factor between an effective and ineffective thermostat for an energy-saving solution.

5. Form factor

While looks don’t count for everything, a space-saving and compact design are highly desirable. Having a thermostat with a touchscreen can also make it easier to control.

6. User interface

A user-friendly interface is something that you will want when it comes to a thermostat. A desirable interface is one that displays only the necessary information without clutter. Necessary information consists of temperature, settings, time, and date.

2. Can you install a smart thermostat yourself?
