Smart Thermostats Compared

Real-world performance in Central NJ homes. Equipment we actually carry & install.

Ecobee SmartThermostat Premium ($250)

Our overall pick. Built-in air quality sensor, remote room sensors (huge for 2nd-floor balance), and Apple HomeKit / Google Home / Alexa. Energy reports tell you exactly where money goes. Heat pump optimization is best-in-class.

Google Nest Learning Thermostat ($249)

Best aesthetics + learning. Auto-adjusts schedule after 2 weeks of use. Slight weakness: heat pump algorithm aggressive on aux heat = bigger winter bills than Ecobee. Otherwise great for simple gas + AC homes.

Carrier Cor / Infinity Touch ($350-$700)

Required for Carrier Infinity / Greenspeed variable-speed systems. NOT compatible with other brands. Best UI of all options if you have Carrier system — comes “free” with most Infinity installs we do.

Honeywell Home T9 / T10 ($170-$280)

Best price/performance. Built-in room sensors (T10). Less polished app than Nest/Ecobee but solid hardware. Good fit for owners who want smart features without paying premium.

Lennox iComfort S30 ($600)

Only for Lennox premium systems. Best when paired with Lennox SLP98V furnace + XC25 AC + Pure Air S air cleaner. Single-system aesthetics + control. Not a standalone purchase.

Mitsubishi kumo cloud / Wi-Fi Module ($150)

For Mitsubishi mini-splits. Adds Wi-Fi control + scheduling to MXZ outdoor units. Each indoor head has its own “thermostat” in the app. Works with Apple HomeKit + Google Home.

Will a smart thermostat actually save me money in NJ?
Yes — typically 8-15% on heating + cooling bills. ENERGY STAR data: average $50-$200/year savings. ROI on a $250 thermostat: 2-3 years. The smarter the home schedule, the more savings.
Do I need a C-wire for a smart thermostat?
Most modern smart thermostats (Nest, Ecobee Premium, Honeywell T10) NEED a C-wire (24V common). Older 4-wire homes often don’t have one. We add a C-wire during pro install — usually $75-$150 extra depending on accessibility.
Can I install a smart thermostat myself?
Yes if: you have a C-wire, your system is straightforward gas + AC, and you’re comfortable with low-voltage wiring. NOT recommended if: heat pump, variable-speed system, dual-fuel, or no C-wire. Pro install is $150-$250.
Which smart thermostat is best for a heat pump?
Ecobee SmartThermostat Premium. Its heat pump algorithm avoids aggressive aux-heat use (the #1 way Nest hikes winter bills on heat pump homes). If you have Carrier Greenspeed heat pump, use Carrier Cor — designed for variable-speed.
Will my smart thermostat work if Wi-Fi goes down?
Yes — all smart thermostats fall back to manual/schedule operation when Wi-Fi is down. You lose remote control but heat/cool still works. Some show offline status — reconnects automatically when Wi-Fi returns.
Are smart thermostats hackable / privacy concerns?
Real but minimal. Nest is Google-owned (you’re already in their data ecosystem). Ecobee is more privacy-conscious. Honeywell is enterprise-focused. None “listen” in the room. All have 2FA available — turn it on.
