What moves the price
Your device or ours
Bought a smart stat online? We’ll install it. Want a recommendation matched to your system? We carry proven ones.
The C-wire question
Many older homes lack the common wire smart stats want. Adapters, spare conductors or a new pull — we sort it cleanly.
What it controls
A single-stage furnace is simple. Heat pumps with backup heat and multi-stage systems need the right stat wired the right way — miswiring burns money invisibly.
Placement
A stat over a lamp or in a sunbeam lies to the whole system. Sometimes the fix includes moving it where it can tell the truth.
Small box, big control.
Book the install — wired right, tested against your real system, priced upfront.

Quick answers
Is a smart thermostat actually worth it?
For most homes, yes — schedules and setbacks commonly trim 5–10% off heating and cooling. On a heat pump, the right stat matters even more, because a wrong one triggers expensive backup heat.
My screen is blank — new thermostat time?
Not necessarily — blank screens are often batteries, a tripped safety or a power issue. Check our blank thermostat guide first; replace it when it’s actually the stat.
