3 Things to Know Before Choosing and Installing a Smart Thermostat

A smart thermostat offers all three benefits by maintaining the optimal temperature for your house, allowing access from anywhere, and lowering your carbon footprint. Who doesn’t enjoy household appliances that make living cozy, practical, and considerate?

It’s critical to equip yourself with the appropriate knowledge to search for the ideal smart thermostat.  Read on to learn about some less well-known aspects you should consider before upgrading.

Choose Your Upgrade Timing Wisely

Everyone loves saving energy, so switching to an energy-efficient thermostat as soon as possible results in the most significant energy savings. However, while it can be tempting to change your thermostat to one that is more energy-efficient, it isn’t necessarily the best option. 

You might not have a working HVAC system for a while while you wait to correct something that goes wrong during a DIY installation. Waiting for milder weather could be preferable. Call our specialists at ESI Heating & Cooling if you have any worries about the installation.

Check For Compatibility Before Buying a Smart Thermostat

It’s crucial to be sure a new thermostat will work with your existing HVAC system when searching for one. Most smart thermostats need 24-volt “low voltage” HVAC systems, sometimes known as “central heat” or “central air,” and you probably have one of these if:

  • Your home has a single thermostat that regulates the temperature throughout.
  • There are one or more large furnaces in your basement or garage.
  • The wires are thin (18 gauge) instead of thick when the electricity is turned off, and the thermostat is removed from the wall (10 to 14 gauge). These cables frequently have several colors.

The other standard HVAC system uses “line voltage,” which is usually incompatible with smart thermometers. These devices, which operate on 120 to 240 volts, can be recognized in the manners listed below:

  • There is a thermostat in each room.
  • Under the lid, there is a high voltage warning.
  • The line voltage is more typical if you have radiant, convection, or resistance heat.
  • You can have line voltage if the vents are in the walls or floors.
  • Line voltage can be present if your house is an apartment or a condo.
  • Additionally, you should confirm that you have a C-wire. Many well-known smart thermostat models have adapters to fix the issue if you don’t have or can’t discover the C-wire.

Consider The Thermostat’s Location

Smart thermostats need a WiFi connection for their best functions, such as remote management. Therefore, ensure your new thermostat is placed in a part of your home with adequate WiFi connectivity if you want the best possible experience. To do this, you might need to relocate the WiFi router in your home.
