Nest thermostat installation in Dallas. $120 flat, C-wire included.

One hundred twenty dollars, flat. That covers removing your old thermostat, labeling the wires, mounting and wiring the Nest, running a C-wire if your wall does not have one, and setting up the app and schedules on your phone before we leave. Ecobee is the same $120 — sensor pairing included.

The C (common) wire gives your thermostat constant 24V power. Many Dallas homes built before the 2010s do not have one at the thermostat, and without it a Nest slowly drains and drops off Wi-Fi — usually in August, when you need it most. We diagnose it in two minutes and run the wire or install the power accessory as part of the same $120 visit. No "we found a problem" upsell at the door.

Honest answer: Ecobee if you have hot or cold rooms — its remote sensors average temperatures across the house, which fits big two-story DFW homes. Nest if you live in Google Home or want the cleanest look on the wall. If you are an Apple household, Ecobee works natively with HomeKit; Nest needs a workaround. We install both every week and will tell you straight.

Texas summers are exactly where smart schedules pay off. Letting the house drift a few degrees while you are at work and pre-cooling before peak rates typically saves 10–15% on cooling costs — which for most DFW homes covers the thermostat and the install within the first two summers.

Yes — heat pumps with auxiliary heat, dual-fuel setups, and multi-stage systems are exactly where DIY installs go wrong, because the wiring is not what the app diagram shows. We label every conductor, configure the thermostat for your actual equipment, and test heating and cooling stages before we leave.

All of DFW — Dallas, Plano, Frisco, McKinney, Allen, Richardson, Highland Park, Southlake, Prosper, Celina, and everywhere between. Most thermostat installs are same-week, and we bundle them with doorbell or camera installs on the same visit for one trip charge of zero.
