WHY HIRE A PROFESSIONAL
The importance of professional smart thermostat installation
A smart thermostat looks like a swap-and-go upgrade, but it actually involves verifying HVAC compatibility, running or adapting a C-wire, configuring the unit to your specific heating and cooling system, and pairing it to your WiFi and any smart-home hubs.
Precision Today is trained on the leading smart thermostat brands, including Nest, Ecobee, and Honeywell, and we have been serving Chicago homes since 1992 across Carol Stream, Oak Brook, Franklin Park, Palos Heights, Grayslake, and the surrounding suburbs. Every smart thermostat upgrade is installed, configured, and backed by upfront pricing and our Precisely Right or We Pay You guarantee.

FAQ
Common questions about Smart Thermostats
Do you offer same-day thermostat replacement?
How much does smart thermostat installation in Chicago cost?
Pricing depends on the brand and model, whether a C-wire run or power-extender kit is needed, and whether the existing thermostat location requires any drywall or plate work. Precision Today provides written upfront pricing before any work begins, with no surprise charges at the end of the visit.
Can I install a smart thermostat myself?
The mounting plate is usually straightforward, but the wiring is where DIY installs go wrong. Heat pumps, dual-fuel systems, multi-stage furnaces, boilers, and zoned systems each need specific wire configurations, and the wrong setup can damage the HVAC control board. If you are unsure about your wire labeling or your system type, a professional install protects the equipment and the warranty.
Which smart thermostat brand should I choose for my Chicago home?
It depends on your HVAC system, your smart-home ecosystem, and your budget. Nest is a strong fit for homeowners already in the Google ecosystem. Ecobee tends to be the most flexible across multi-stage systems and remote room sensors. Honeywell offers reliable WiFi thermostats with the broadest compatibility across older systems. Your Precision Today technician will walk you through model differences during the in-home estimate.
Does my HVAC system need a C-wire for a smart thermostat?
Most modern smart thermostats need a C-wire (common wire) for continuous power. Many older Chicago homes do not have one at the thermostat location. Our technicians can usually run a C-wire from your furnace or air handler, or install a power-extender kit, as part of the smart thermostat upgrade so the unit runs reliably and does not drop offline.
What is a smart thermostat, and how is it different from a programmable thermostat?
A programmable thermostat lets you set a fixed weekly schedule on the wall unit itself. A smart thermostat does that plus much more: it connects to your home WiFi, learns your patterns over time, lets you control the temperature from your phone, integrates with voice assistants and home automation platforms, and reports energy usage so you can see where savings actually come from.
How often should my heating system undergo maintenance?
We recommend scheduling annual maintenance in the fall to keep your system running smoothly all winter.
What factors should I consider when thinking about a heating system replacement?
Consider the age of your system, how often it needs repairs, and its current efficiency. Precision Today is ready to discuss your options.
Are there energy-efficient furnace options available?
Yes. We offer a range of energy-efficient furnaces to meet your needs and save on energy costs.
