What Should You Know About Ac Thermostat Installation?

There are professionals out there who claim that the usage of a programmable thermostat helps in saving at least about 10% of the cooling and heating bills monthly. Hence, many of us end up taking the usage of the AC thermostat for granted, but in reality, it is one of the essential components to be used as it can help in saving a significant amount of cost.

Installing a programmable thermostat will likely result in increased savings and heating bills as these devices can be set to automatically adjust the temperature based on the time of the day and occupancy, so you aren’t paying to heat or cool the home when no one is at home. Of course, you can also hire a professional thermostat installation company, especially for programmable thermostat installation. Still, you need to know that learning how to install the best thermostat helps keep the cost down.

Before starting your thermostat installation, you need to learn about the existing thermostat on the wires that run from the furnace to the thermostat to determine if the current start setup is suitable for the best thermostat or if any additional wire will be needed. For example, suppose the aim is to install a standard programmable device. In that case, this inspection can be used to familiarize yourself with the thermostat’s wiring and learn exactly where it needs to connect to the furnace.

It would be best if you also took time to measure the whole behind the thermostat to ensure that the replacement thermostat is big enough for enough faceplate to cover the hole.

Remove the old thermostat from the wall.

You need to turn off the breaker to your furnace and the air conditioning system while taking the cover off the old thermostat. Several lids pop off with slight pressure, but some bodies need to be unscrewed. Then you need to carefully put out the old thermostat but leave the wire connected.

For future reference, label the wires.

At the same time, it is also important for labeling of the wires, which is a significant part of the installation process. All you have to do is, to attach one masking tape on each of the wires, then write that very letter which helps in indicating the wire connection to the old thermostat.

Disconnecting From the Wires from The Very Own Thermostat Which Is Existing

You need to take the current miles to the wall or grab them around a pencil or some screwdriver so that they don’t retract in your wall cavity the moment you disconnect them from the old thermostat. Experts suggest you take extra care at this point so that you are saved from a great deal of unnecessary aggravation.

Install the faceplate while confirming the wiring

It is not directly wired to a power source if only two wires are connected to the existing thermostat. However, there are chances that there is a direct wire with more than two wires, and you are free to buy from a broader range of replacement models. You can also attach the faceplate to the wall included in the fast nurse and then thread the wires through and connect them to a new thermostat.

Finish installing the thermostat by connecting the wire

It would be best to match the letters on the labeled wires to the thermostat as you connect the wires to the new thermostat. Then you need to install the required batteries and attach the thermostat to the faceplate. Lastly, you need to snap on the thermostat to finish the job. It would be best if you didn’t forget to turn the breaker back on to restore power to the furnace and air conditioner.

Installing a thermostat professionally versus DIY

Ideally, the cost is not the only factor you need to consider, even though it is essential to decide whether you should call an expert thermostat installation company or complete the thermostat installation yourself. Several thermostat installations include removing the old thermostat and connecting a new thermostat using the same wires, then mounting the new device in the same spot. Completing the installation yourself is easy and quick, but that does not involve booking appointments and waiting for technicians. But if the wiring from the furnace’s thermostat is damaged or lacks the necessary wire to connect a smart thermostat, then the job can become quite challenging.

The heating and cooling system cannot be operated without any thermostat, so it is better to pay a professional to ensure that the work gets done right if you like the experience to finish the installation. The companies will generally include a guaranteed period within which you can call them if something is not right so you can be relaxed, knowing that you wouldn’t be on your own trying to figure out while freezing or roasting.

How many thermostats do you need?

The minimum number of thermostats that are important to operate a heating and cooling sister in the house is generally one. It is the central thermostat that is installed typically on the middle floor of the house, allowing it to record the median temperature between the bottom and top floor of the house. But this placement can result in hot and cold zones throughout the house because the thermostat can only register the temperature within the instant vicinity.

By dividing the house into heating and cooling zones, you can get a more accurate temperature reading and more even heating throughout the home. Zones include the entire floor, several rooms or just one room. For example, several people spread the house into two zones, requiring one thermostat for each zone.


When it comes to installing the best thermostat, you must decide whether you can do it DIY or you need to hire a professional. When a thermostat starts failing, it can cause temperature fluctuation inside the home and might result in higher heating and cooling bills.
