Home theater installation: what to know

What the job involves, what changes the price, and what to ask a pro.

What home theater installation is

Home theater installation plans and sets up a screen or projector, speakers, a receiver and the wiring in a room, hides the cables, calibrates the sound and picture, and programs a simple remote. People hire it when they want a dedicated movie or game room that works on the first night and looks clean.

Signs you need it

  • You are building or finishing a room for movies, sports or gaming, and want it set up properly
  • You have a TV or projector and a receiver, but the cables are tangled and the sound is weak
  • You want a screen or projector mounted and aligned to the seating area
  • You want the cables hidden inside the wall or behind the screen
  • You want the remote, the receiver and the TV to work together with one remote

What the pro does

  • Plan the seating, the screen or projector position, the speaker placement and the cable routes
  • Mount the screen, the projector bracket or the TV, aligned to the seating and the light conditions
  • Run the in-wall speaker cable, HDMI and other low-voltage cable through the walls or ceiling
  • Install the receiver, amplifier, media player and rack, then connect them to the display
  • Calibrate the picture and the sound, including speaker levels, distance and the room's acoustic issues
  • Program the remote, show the owner how to use each input, and leave a written setup sheet

What changes the price

Every job is different, so we do not publish prices. These are the things that move the quote up or down.

  • Screen size and type, such as a TV, a fixed projector screen, or a motorized screen
  • Projector type and mounting, including ceiling mounts and lens positioning
  • Number of speakers and whether they are in-wall, in-ceiling or freestanding
  • Cable runs through walls, ceilings and floors, and how much finished surface must be opened
  • Receiver and amplifier power, plus any media player or streaming device included
  • Whether new outlets, circuits or a dedicated power line are needed, which often calls for a licensed electrician
  • Room acoustics, such as hard walls, large windows and high ceilings, which affect the sound

What a written quote should spell out

  • The screen or projector brand, model and size, and the mount type
  • Each speaker listed by model and location, with the receiver or amplifier named
  • Cable types and runs, including speaker wire, HDMI and any low-voltage cable
  • Wall, ceiling or floor work listed as a separate line, with the repair of any finished surface
  • Any new outlet or circuit listed for the licensed electrician
  • Calibration, remote programming and training as separate lines, with the warranty terms

Questions to ask before you hire

  • Should I choose a TV or a projector for this room, and why?
  • Where will the speakers go, and how do you decide the placement?
  • Which cables will you run inside the walls, and how are they rated?
  • Who handles any new outlet or power circuit for the room?
  • How do you calibrate the picture and the sound for this room?
  • Will I be able to control everything with one remote?
  • What warranty covers the screen, the projector, the receiver and the labor?

Red flags

  • They plan the install without seeing the room, the seating or the light
  • They run cable without checking the cable type for the signal it carries
  • They leave the power work to the homeowner or an unlicensed helper
  • They skip calibration and only plug in the components
  • They leave the remote programmed to their own preferences, not yours

What you can do yourself

A homeowner can choose the seating layout, pick the screen or projector, and test which room positions give the best view before the install. Do not run new power or add outlets yourself, and check for wiring, pipes and framing before you open a wall or ceiling for cable. Call a pro for mounting, in-wall cable, speaker placement and calibration.

Licenses and permits

Home theater installation often needs a licensed electrician for any new outlet or power circuit, and a permit may be required when walls or ceilings are opened. Check with your state or local licensing agency and your local building office for the rules that apply to your room.

Home theater installation questions

Is a projector or a large TV better for a home theater?

It depends on the room's light, the viewing distance, the screen size you want and how much you plan to use it in daylight. Ask the installer to compare both in your room and to explain the trade-offs.

Do I need in-wall speakers?

In-wall speakers look cleaner, but they require walls to be opened and cable to be run. Freestanding speakers are easier to place and move. Ask the installer what your walls allow and what the sound will be like.

Why does the picture look wrong after the install?

Common causes include the wrong input setting, a cable that cannot carry the signal, or a picture mode that is not set for the room. A calibration can fix most picture issues, so ask the installer to check the setup.
