0% for 25 months on a qualifying new Rheem® heating or cooling system. Installed by November 15.
The Thermostat Is Mounted Like a Fixture
It goes on level and plumb, checked with a one-foot level on the mounting plate, backed by the back plate it comes with, secured to a stud or drywall inserts, with no loose play and the wire hole sealed against drafts.
Wired So the Next Tech Can Read It
Low-voltage wires are run straight, kept neat, and left with slack coiled for the future, so a technician can trace them without taking your work apart.
Stripped So It Never Shorts
The outer jacket on a wire bundle is opened with a razor, not squeezed with wire strippers. If strippers were used, the end they gripped is cut off, because a nicked wire is what causes a short down the road.
The thermostat is mounted solid and level
The thermostat goes on level and plumb, checked with a one-foot level laid on the mounting plate, and is secured into a stud or with drywall inserts so there is no loose play and no chance of it pulling off the wall over years of use. A back plate goes on every thermostat we install. It is what the thermostat itself mounts to, and a stat that does not come with one is a stat we will not put on your wall. The hole the wire comes through is sealed, normally with thumb gum, so air moving inside the wall cannot reach the thermostat and throw off what it reads.
It is left clean and set up for your system
The thermostat is wiped free of any dirt or grease, a touch screen is left free of fingerprints and scratches, and the wall behind it is checked and cleaned the same way. Before we leave, it is configured for your exact system type, whether that is a heat pump, gas, air conditioning, or a staged system, because a thermostat set up for the wrong equipment type controls it wrong even when everything else was installed right.
The wiring is run straight and secured
Low-voltage wiring is run straight along the outside of the equipment, secured with proper grommets and clamps so nothing rests against a sharp edge or hangs loose. Where the wire passes into the cabinet itself, the standard that applies is the one on our air handler page, so this page does not restate it. It is neat because neat is what stays working: wiring that is dressed and clamped does not chafe, snag, or get pinched the next time a panel comes off.
It is wired for the next technician
This is the standard most installers skip. Each wire is left a consistent 2 to 4 inches long at the terminal so a future technician can see at a glance what goes where without taking your work apart. Wherever possible, an extra 8 to 12 inches of low-voltage wire is left inside the equipment, coiled with the curl method, so the next equipment change has slack to work with. Extra wires are wrapped neatly around the main bundle for future use. On a zone panel, every wire is run so it can be traced without moving anything.
It is done safely
The rule on a bundle of low-voltage wire is that no conductor inside it reaches a terminal nicked. The jacket is opened with a razor or a knife, or, where wire strippers have been used on the bundle, the section they gripped is cut off before anything is connected. A scored conductor will run fine for months and then short, which is why the standard is written about the wire and not about the tool. Where multiple safety switches are wired they go in series, so any one of them failing still shuts the whole system down, and the full switch standard is on our condensate page. On a communicating system we check the board for a dedicated safety-switch terminal before wiring one in, and interrupt the R or Y circuit only, never a data signal.
