Although thermostat replacement costs don't vary much from project to project, some factors might raise or lower the price a little.
Labor
Most local electricians can install or replace a home, apartment, or business thermostat in two hours or less at around $65 to $100 per hour, for a total labor cost of less than $200. Whether you opt for a modern, digital model or a simple, manual one, the installation costs won’t differ significantly. It's still an electrical job, regardless of your thermostat choice.
Number of Units and Zones
If you need multiple units installed in your home, ask your pro what the price would be to put them in all at once. Although the overall charge may be higher, the per unit rate will almost always be considerably lower if a pro only needs to make one trip to your home.
To set different temperatures for different home areas using one HVAC unit, you'll need a multizoned system with electronic baffles. On top of the price of the units, you'll need to factor in material and labor costs. Baffle charges will vary based on your home's duct sizes. In addition, factor in labor for both a licensed HVAC professional near you and an electrician since this job is too complicated to do yourself.
Repairs
Although unlikely, you may need to make some minor repairs to your home, such as cutting small holes in drywall to run wires. But this is rare, and you’ll likely pay around $50 to $150 to patch a small hole or two. In this case, you might consider installing a wireless smart model.
New vs. Replacement
The main cost difference between a new and a replacement is the wiring. You'll pay an extra $100 to $200 to run wires to your HVAC system. In cases like this, it's generally better to spring for a smart home system that connects wirelessly to your furnace and AC unit.
Accessories and Add-Ons
Modern accessories include smart home systems like hubs, lights, locks, and even window shades. Smart home costs range from $50 to $300 for each item, which can quickly add up to a smart home system cost of $1,500 or more.
