The right thermostat knows your schedule, adapts to the weather, and keeps every room comfortable without you thinking about it. We install, program, and repair all major smart thermostat brands — and we make sure you actually know how to use it.
If your thermostat still has a dial or basic display, your home isn't as comfortable or in control as it should be.
Not sure which type you have? We assess your wiring and system before recommending any model.
We stock and install the best thermostats available — and we know which one works best with your specific heating and cooling system.
Built-in Alexa, room sensors included, exceptional multi-zone control. Our most recommended choice for Seattle homes — the remote sensors solve the cold/hot room problem that single thermostats can't.
Self-programs by learning your patterns in about a week. Sleek circular design. Best choice for Google Home households and anyone who doesn't want to configure schedules manually.
Reliable, proven, and budget-friendly with full smart features. The professional's choice when a full-featured smart thermostat isn't needed but you want Wi-Fi and scheduling done right.
Excellent choice for older homes without a C-wire — works on most 2-wire setups. Full touchscreen display, app control, and flexible scheduling without the rewiring hassle.
The top-tier choice for Lennox system owners. Deep integration with Lennox equipment unlocks variable-speed and multi-stage control that third-party thermostats can't access — maximum efficiency from your existing system.
The right thermostat depends on your heating system type, wiring, smart-home ecosystem, and budget. We assess your setup and give you an honest recommendation — not the most expensive option.
Installation is only half of it. We configure, program, and test everything before we leave — and we show you exactly how to use it.
Supply & install a new smart thermostat
We handle everything from verifying your wiring (C-wire check, adapter install if needed) to mounting, connecting to Wi-Fi, programming your first schedule, and a full walkthrough so you know every feature.
Upgrade from old to smart
Already have a thermostat but want to upgrade? We assess whether your existing wiring supports the new model, handle any needed C-wire additions or adapters, remove the old unit cleanly, and configure the new one from scratch.
Get more from the thermostat you have
Most homeowners never get past the default settings — and leave most of the savings on the table. We configure advanced schedules, geofencing, humidity targets, and integration with other smart home systems.
When your thermostat misbehaves
Blank screen, short cycling, system not responding to temperature changes, Wi-Fi keeps dropping, or the schedule randomly resets — we diagnose the root cause. Often it's the thermostat; sometimes it's the wiring or the HVAC system behind it.
These are the things homeowners notice every day after the install — none of them require you to think about your thermostat at all.
Geofencing and scheduling mean your home starts heating or cooling before you arrive — not after. You walk in to the right temperature. No more turning it up and waiting 45 minutes.
Smart thermostats respond to weather changes before you feel them. Instead of swinging 4–6 degrees, your home holds its target more tightly. Especially noticeable on cold Seattle mornings and warm afternoons.
Left for a long weekend and forgot to turn it down? Heading back early from vacation and want the house warm? One tap from your phone, wherever you are. No more coming home to a house that's been heating since Tuesday.
Smart thermostats monitor your system's behavior and flag unusual patterns — extended run times, short cycling, or failure to reach setpoint. You find out via app notification, not by waking up cold at 2am.
Remote sensors (like Ecobee's SmartSensors) detect which rooms are occupied and prioritize comfort where people actually are. The bedroom is right at bedtime. The living room is right in the evening. Not just wherever the thermostat happens to be mounted.
A smart thermostat can set a cooler overnight temperature automatically — the range that research links to deeper sleep — and bring the house back to a comfortable morning temperature before your alarm goes off. No manual adjustment, every night.
"I put off the upgrade for years. After Next Phase installed the Ecobee and set it up properly, my PSE bill dropped $42 the first month. It paid for itself before spring. Wish I'd done it sooner."
"The tech didn't just install it — he actually sat with me for 20 minutes walking through every feature. I'm actually using the geofencing and schedule now. Never happened with the last company."
"My old Nest was acting up — short cycling and randomly going blank. Called Next Phase, they diagnosed a wiring issue in 20 minutes, fixed it on the spot. No parts needed, no up-sell. Just fixed."
"Had a Honeywell dial thermostat from the 90s. Next Phase replaced it with a Sensi Touch — perfect for our older wiring. The house stays comfortable now and the app is genuinely easy to use."
"Lennox system so I went with the iComfort. The tech knew the system cold and had it set up in under an hour. The variable-speed integration is noticeably quieter and more even heating."

Many smart thermostats require a C-wire (common wire) to power themselves. Some older homes don't have one. If yours doesn't, we can usually add a C-wire adapter or run a new wire depending on your system. Some models like the Emerson Sensi are designed specifically to work without one. We assess your wiring before recommending any model.
Yes, but heat pumps require specific thermostat wiring (O/B reversing valve wire) and ideally a model that understands emergency/auxiliary heat stages. The Ecobee and Honeywell T6 Pro both handle this well. Installing the wrong model or wiring a heat pump incorrectly can cause it to run inefficiently or not at all — which is why professional installation matters here.
A single thermostat mounted in one location only measures temperature there — not where you actually spend time. Thermostats with remote sensors (like the Ecobee SmartSensor) can monitor multiple rooms and factor them all into when your system runs. It's the most effective fix for uneven comfort without touching your ductwork.
Technically, yes — for simple 2-stage forced-air systems with correct wiring. But heat pumps, multi-stage systems, zoned systems, and anything requiring a C-wire addition can go wrong quickly. The risk isn't just a failed install — it's potential damage to your HVAC equipment or short-cycling that wears out your system. Professional installation ensures the thermostat is configured to actually match your system's capabilities.
Not always. A blank screen is often a power issue — dead batteries (on battery-powered models), a tripped breaker, or a loose C-wire connection. Before calling us, try replacing the batteries if applicable and check that the furnace or air handler breaker is on. If those don't help, call — it could be wiring, a failed thermostat, or a problem with the HVAC equipment itself.
We install it right, configure it fully, and walk you through every feature before we leave. You'll actually use it — and your home will feel different from day one.
