"Jonace of 3 Angels Electrical was a breath of fresh air. I posted a request on Angi’s List to install a new LED Kitchen Ceiling Light. He texted me within minutes for details of the job and even ask how much I wanted to pay, this left me speech-less for a minute. He was clear on price once I explained the scope of the job. I appreciated his followup and being flexible. New light installed and no more flickering problems. I have several other electrical projects and will use him without hesitation and refer him to family and friends."

Stereo and Home Theater Systems questions, answered by experts

Costs range from $1,000 to $5,000, depending on system complexity and components.

Yes, installing a home theater is worth it for the opportunity to create a movie theater-level experience in your own home, especially if you want to upgrade how you entertain guests, watch movies, and play video games. Your budget determines the size and capability of your in-home theater, so the value you derive from the home theater you can install depends on your needs, expectations, and how often you use the space. Consider choosing your home theater features based on the value they’ll bring to users to ensure you invest your project budget wisely.

Identifying the source of noises is your first step to soundproofing a room without overspending. Generally, sound comes from inside or outside of the house. Inside noises include creaking floors, living noises like TVs in the living room, cooking sounds, or kids being kids. External noises generally include incremental weather, disturbing neighbors, and street traffic. Inside noises require you to soundproof floors, ceilings, and doors, whereas outside noises may require you to soundproof your attic, windows, and walls facing the streets.

Professionals calibrate the system for immersive audio, eliminating sound delays and improving acoustics.

Costs depend on system size, equipment type, and wiring complexity.
