Yes, you should get a quote or an estimate from an electrician. Most electricians offer free estimates or quotes. When getting quotes, do your research and verify each electrician’s license. Get quotes from three different electricians to compare. If the prices or items listed appear different on the quotes, ask the electrician to clarify. Learning as much as you can about the electrical work you want done will help you get the most accurate estimate.
Qualified, licensed electricians will charge from $50 to $100 per hour. The cost to hire an electrician for emergency visits may range from $100 to $200 per hour because this urgent service usually takes place during off hours and may require an electrician to leave or reschedule jobs they’re currently working on. Scheduling work on holidays or during periods of high customer demand, like after a major storm, will also lead to higher rates or extra fees.
An accredited, licensed smart home specialist should install your home automation system. For example, a qualified smart home specialist will belong to an organization like the Custom Electronic Design & Installation Association. Licenses for qualified technicians require the technician to demonstrate experience and pass state testing. If you’re ready to install a home automation system, consult multiple technicians in your area to compare services and prices and find the best fit for your job.
The average cost of a home automation system is around $950, but typically ranges from $200 to $1,700, depending on the brand, system features, system size, home size, and location. The highest-end home automation systems can cost anywhere from $10,000 to $150,000, including smart appliances like refrigerators, dishwashers, and ovens that require installing extensive wiring. Any subscriptions for maintenance services will also impact the cost of a home automation system.
