Nest vs Ecobee vs Honeywell

The single biggest difference between these three smart thermostats is how they read your home and how they handle humidity, which matters more in Tampa Bay than just about anywhere else in the country. The Nest Learning Thermostat (4th gen) ships as a single unit with no remote sensors in the box. It relies on its built-in temperature, humidity, and proximity sensors plus a learning algorithm that watches your behavior for a week or two and builds a schedule on its own. Nest does display indoor humidity, but it has no humidity setpoint and no overcool function, so the thermostat will not run the AC longer just to pull moisture out of the air. In a Tampa August, that is the weakest link of the three.

The Ecobee SmartThermostat Premium is the opposite philosophy. You get one SmartSensor in the box, with support for up to 32 more, and the thermostat averages temperature and occupancy across every sensor in your follow-me group. More importantly for our climate, Ecobee has a true humidity setpoint and an overcool-to-dehumidify mode that lets the AC run an extra 1 to 2 degrees past your temperature setpoint when indoor humidity climbs above your target. That single feature is why most Tampa homeowners who care about sticky air end up on Ecobee.

The Honeywell T9 sits in the middle. It includes one wireless RedLink room sensor, supports up to 19 more, and has a clean humidity setpoint with auto-changeover between heat and cool. T9 also has the strongest native geofencing of the three, using your phone’s location to switch between home and away modes without you touching anything. All three units now support Wi-Fi and either Thread or Matter on the newer revisions, and all three integrate cleanly with Alexa, Google Assistant, and Apple HomeKit (Ecobee leads on HomeKit polish, Nest leads on Google Assistant tie-in).

If you live in Tampa and you only care about one thing, pick the thermostat that handles humidity best, because that is what makes a home feel cool at 76 degrees instead of clammy at 74. Ecobee wins that contest. The overcool-to-dehumidify mode is the most aggressive of the three. When indoor RH climbs to 60 percent and you have a target of 50, Ecobee will let the AC run a degree or two below your temperature setpoint to wring the moisture out of the air, then back off. Nest cannot do that. Honeywell T9 has a humidity setpoint but no real overcool function.

If your priority is whole-home zoning awareness, Honeywell T9 wins. The included room sensor plus the strongest native geofencing of the three make it the right pick for a multi-story house or a homeowner who wants the system to lean toward whichever room is occupied. T9 is also the easiest to retrofit into an existing schedule.

For Tampa Bay snowbirds and retirees who head north May through September, both Honeywell geofencing and Ecobee remote sensor monitoring are useful. You can drop the home into away mode automatically when your phones leave the area and pull live indoor humidity, temperature, and runtime data from anywhere with cell service. We have customers who catch a failing AC from an airport in Michigan because Ecobee texted them that indoor humidity hit 65 percent.

All three work with Goodman and Daikin variable-speed equipment over standard 24V control, which covers the majority of Tampa installs. If you have a fully communicating Goodman ComfortBridge or Daikin One+ system, you can either run the smart thermostat in 24V mode (you keep variable-speed but lose some advanced staging) or stay on the manufacturer’s communicating thermostat. We will tell you which way to go after we look at your equipment.

Nest vs Honeywell: which is better for a Tampa home?

Honeywell, if humidity is your main complaint. The Honeywell T9 has a real humidity setpoint, comes with a room sensor, and has the strongest automatic home and away switching of the three. The Nest Learning Thermostat has the best app and learns your schedule on its own, but it has no humidity setpoint and no overcool mode, so it will not run the AC longer to dry out a sticky house. Pick Nest if you live in the Google Home ecosystem and your humidity is already under control.

Ecobee vs Honeywell: which is better?

Ecobee for humidity, Honeywell for simple set-and-forget sensing. Ecobee’s overcool-to-dehumidify mode lets the AC run a degree or two past your setpoint to pull moisture out, which the T9 does not really do. Ecobee also supports more than 30 room sensors and works best with Apple HomeKit. The Honeywell T9 comes with one sensor, supports up to 20, and costs less up front.

Honeywell T9 or T10 vs Ecobee

The T9 is the consumer model you can buy at retail. The T10 Pro is sold through HVAC contractors, uses Honeywell’s RedLink wireless sensors, and needs a C-wire. Both have a humidity setpoint. Against the Ecobee Premium, the T10 makes sense if you want contractor-installed sensors and support, while Ecobee still has the more aggressive dehumidify mode. Honeywell Home thermostats are made by Resideo, the company Honeywell spun off in 2018.

All three work with our preferred Goodman and Daikin systems, and with most other brands, over standard 24V wiring. We check your wiring and recommend the right one during a FREE estimate.
