If your thermostat isn’t working properly, you’ll probably need to have it replaced. But what does it cost to have your thermostat replaced?

Here’s our guide to what it might cost you in parts and labor. Starting with:

Thermostat replacement cost: What does it cost not to replace it?

The thermostat is a vital part of your home HVAC setup. So, if it isn’t working properly, it could be costing you hundreds of dollars per year. Why? Because it could be incorrectly heating or cooling your room, forcing you to have to continually change your thermostat setting. Over time, this over heating or over cooling costs a lot of money! That’s why buying a new thermostat, although you might be put off by the cost of installation, actually saves you money in the long term.

But, like all things in life, the cost depends on the quality you would like. There are three different kinds of thermostat which you can choose from. These are mechanical, non-programmable and programmable. Let’s find out what it costs to have each kind installed!

Thermostat replacement cost: Mechanical/manual thermostats

Mechanical, or manual thermostats are the old fashioned kind which you probably already have in your home. In order to set the temperature, you have to manually turn a dial to choose your setting. Now, we aren’t saying it’s the end of the world that you have to turn a dial, but these thermostats are undeniably outdated!

Even so, you can still buy mechanical thermostats, and they can save you a fair amount on the cost of installation. Manual thermostats can cost as little as $25, up to about $50. They typically have a long product lifetime, too, so they’re remarkably cheap. The only downside is, of course, that you have to remember to adjust the temperature when you leave the house.


Thermostat replacement cost: Non-programmable thermostats

Non-programmable thermostats are basically more expensive and more modern versions of mechanical thermostats. Instead of manually turning a dial, you manually change the temperature using buttons. As you can see from the picture to the left, they aren’t necessarily the most modern! So for many homeowners, they are often the kind of thermostat that ‘comes with the house’.

Like mechanical thermostats, they are typically cheaper than more modern variants like the Nest, Sensi or Ecobee smart thermostats. You can probably pick one up for about $100.


Thermostat replacement cost: Programmable thermostats

Last but certainly not least, we have programmable thermostats. The modern variety of these are called ‘smart’ thermostats, because they’re just that- smart. They can be programmed to turn off or on while you’re outside of the house using an app on your phone. But some smart thermostats are what we call ‘learning’ thermostats: they respond to environmental cues. So, say for instance that you cook the family dinner between 6 and 7pm every night (optimistic, I know). A smart thermostat can detect that pattern, and cool your house just a little bit so that it counteracts the heat from the oven and pans.

The only problem is that functionality like that comes at a price. The exact cost of a smart thermostat can vary, because there are a number of different brands. We’ve broken down the costs below.

  1. Honeywell are one of the best known smart thermostat brands. At the cheaper end, some are less than a hundred dollars, whereas their top range can cost over $500.
  2. The Nest retails at around $250.
  3. The Ecobee is around the same price, although the ‘Lite’ version costs less, at around $170.

Thermostat replacement cost: What does labor cost?

The main cost of having your thermostat replaced by a professional is the labor cost. If you didn’t know, technicians who work for businesses like ours charge by the hour. This means that the complexity of the thing you’re installing has a direct effect not just on the price of parts, but of labor, too.

Installing a mechanical thermostat is fairly easy, and should take no more than an hour. But installing a smart thermostat can often take longer. This means that not only will buying a smart thermostat cost more, but its installation will too.

That’s not to say that we don’t recommend a modern smart thermostat, though. You should definitely consider one if you own your own home, and don’t plan on moving in the near future. That’s because smart thermostats are far more efficient. Learning thermostats respond to their environment, and will automatically turn off while you’re out the house. Just the few times that your thermostat remembers this, whereas you would forget to turn off your heating/cooling manually, will make significant savings. And the savings that you could reap over the course of just one year will go a long way towards repaying those initial costs.
