What's included
What our smart thermostat installation includes
Every install covers the control side of your system end to end. If your wiring needs a new run or your equipment needs special staging, we handle it on the same visit and tell you the price before we start.
Mounting and trim plate
The new base plate goes on level, and we fit a trim plate if the old thermostat footprint was larger. Drywall anchors go in where needed so the unit does not flex when you press the screen.
Equipment configuration
We enter your furnace or heat pump type, stages, fuel source, and fan delays. Heat pump changeover temperature and aux heat lockout get set here, which is where most DIY installs fall short.
Wi-Fi and app pairing
We connect to your 2.4 GHz network, link your Nest or Ecobee account, and build your first schedule. You get a walkthrough on your own phone so you can adjust it later without calling us.
Full cycle test
We run heat, cool, and fan calls and confirm the equipment responds at the right time. If a capacitor, contactor, or blower motor is failing, we will see it during this test and flag it before we leave.
How it works
Our smart thermostat setup process, step by step
We shut off power at the furnace switch and test the existing thermostat wiring with a multimeter. This takes about 10 minutes and tells us whether you have a C-wire or need one run. We also check the air filter and note the furnace brand and model.
We label the low-voltage wires, remove the old base plate, and mount the new one level. If your bundle is short, we pull a new 18/5 run or install an add-a-wire kit. This step runs 20 to 40 minutes depending on wall access.
We power the unit back up, walk through the setup wizard, and enter your equipment type, stages, and fuel source. Heat pump changeover and fan delays get set here. This is where most DIY installs go wrong, and it takes 15 to 20 minutes.
We connect the thermostat to your 2.4 GHz Wi-Fi, create or link your Nest or Ecobee account, and set your first schedule. You get a walkthrough of the app on your own phone so you can adjust it later without a call.
We run a full heat, cool, and fan cycle and confirm the equipment responds at the right time. Then we show you the schedule, the filter reminder, and the away settings. Total visit is usually 60 to 90 minutes.

Tools & methods
Tools and methods behind a clean install
Multimeter
Verifies 24-volt power at the base plate and confirms each wire's function before we mount anything. It is the first tool out of the bag on every install.
Thermostat screwdriver set
Precision tips for terminal screws on Nest, Ecobee, and Honeywell base plates. Stripped terminals are a common DIY problem, and the right bit prevents them.
18/5 low-voltage wire
Used to run a new common wire on older Milwaukie homes with two-wire or three-wire bundles. We pull it through the wall cavity and terminate at the furnace board.
Add-a-wire kit
A faster option when running new wire is impractical, like on finished walls. It multiplexes the existing conductors so the thermostat still gets a common wire.
Clamp meter
Checks current draw on the furnace and air handler during the cycle test. It catches a failing blower motor or contactor before it becomes a no-heat call.
Leak detector
Used on heat pump installs to confirm no refrigerant issues are hiding behind a control complaint. If the system is low, no thermostat setting will fix it.
Real results
Before and after.
Smart thermostat installation
Two-wire ranch gets a C-wire
A 1955 ranch in Ardenwald had a two-wire thermostat bundle and a Nest that kept going offline. The homeowner was resetting it two or three times a week and the schedule never held through a workday.
After: We pulled a new 18/5 bundle in about 35 minutes, mounted the base plate, and configured the unit for the single-stage furnace. The thermostat has stayed online since, and the app shows no dropouts over the past month.

Heat pump stops running strips
A North Clackamas home with a Rheem heat pump ran aux heat almost constantly through the winter. The thermostat was configured as a single-stage gas furnace, so the compressor never carried the load.
After: We corrected the equipment type, set the changeover temperature, and enabled aux lockout. The strips now run only on the coldest mornings, and the homeowner reported a noticeably lower electric bill the following month.

Upstairs bedroom finally matches
A Lake Road two-story had an upstairs bedroom that ran several degrees warmer than the hallway thermostat. The family was adjusting the setpoint all evening and still could not get comfortable.
After: We installed an Ecobee Smart Thermostat Premium with a remote sensor placed in the bedroom. The system now averages both readings on schedule, and the upstairs room holds within about a degree of the setpoint.

Thermostat problems we fix for Milwaukie homes
Most thermostat complaints trace back to wiring, configuration, or a control that was never matched to the equipment. Here are the ones we see most in Milwaukie and how we handle them.
Ask a pro →Smart thermostat keeps dropping offline
This is almost always a missing or loose C-wire. We test voltage at the base plate, run a proper common wire if needed, and confirm the unit stays powered through a full heat and cool cycle before we leave.
Furnace short-cycles after a thermostat swap
We check staging, fan delays, and the anticipator settings against your equipment. Most of the time the thermostat was configured for a single-stage unit when the furnace is two-stage, and correcting the menu fixes it.
Heat pump runs aux heat all winter
We set the changeover temperature and aux heat lockout for your specific heat pump, whether it is a Rheem, Daikin, or Mitsubishi Electric unit. That keeps the compressor doing the work until it actually gets cold enough to need strips.
Rooms never match the thermostat reading
We install a thermostat with remote sensors, like the Ecobee Smart Thermostat Premium, and place the sensor in the room that drifts. The system averages or prioritizes that room based on your schedule.

Most installs run $150 to $350 in labor, and $180 to $450 total if you need a new C-wire run. The thermostat itself adds $130 to $280 depending on the model. Same-day and after-hours slots may carry a small premium. We quote the full job before we start, so you know the number up front.
Licensed HVAC technicians do, and that matters when your wiring needs a common wire or your heat pump needs specific changeover settings. ThermexaPro covers Milwaukie and Clackamas County with NATE-certified techs. We handle Nest, Ecobee, and Honeywell installs and test the full heat and cool cycle before leaving.
You can if you have a C-wire and a single-stage furnace, and plenty of homeowners do. The trouble starts with two-wire bundles, heat pump changeover settings, and multi-stage equipment, where a wrong jumper or menu setting causes short cycling. If your system is anything but basic, a pro install saves you the guesswork.
For most Milwaukie homes, the Nest Learning Thermostat and Ecobee Smart Thermostat Premium are the two we install most. Nest is simpler to run; Ecobee ships with a remote sensor that helps with rooms that never match the hallway temperature. If you have a heat pump or multi-stage equipment, we match the model to your system.
