"We called Dalcon Electric when a car struck a power line outside of our building and knocked out the electricity to our building. They were quick to respond in an emergency, courteous and professional. They helped us get our business back on track in a pinch. Then, we hired Dalcon to replace all 53 outdated outlets in our building. Dave and his crew (Jack and Billy) completed this efficiently and with minimal disruption to our business. When we needed to install emergency exit signs, Dalcon provided by far, the best quote for the work to be done compared to many other handymen we had considered. Jack and Billy installed our emergency signs and cleaned up the area where they had worked leaving it just as, if not better than, how they found it. Everyone at Dalcon is courteous, prompt and responsive. Dave, the owner, came in person to our office to discuss each project to be done. Scheduling these projects was a breeze, Sarah and Suzanne in the office were very responsive and made sure our concerns were addressed. We scheduled the projects out over time, but when a sooner date became available, someone from Dalcon would call and ask if that time would work for us so we could have our projects completed sooner. We would definitely work with Dalcon Electric again."

"Called this company for their $77 dollar, which they advertised with a flyer, for a tune-up and cleaning for my heating system. They are a Hayward company and I was told that our Castro Valley home was not in their service area. I bet if I called to buy a new heater they would be out in a day."

The average cost of a home security system is about $700, ranging from $280 to $1,150. Costs to consider include equipment, surveillance fees, and other additional features. Cost factors that determine your system’s price include the type of security system, materials, labor, activation fees, monthly fees, and permits. Additional features and upgrades may include:
Video surveillance monitoring: $40–$65 per month
Smart home locks: $150
Smart home lighting: $15–$90
Smart smoke, fire, and carbon monoxide alarms: $35–$100
Smart thermostat: $130–$500
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.
Yes, a home security system can be worth it for your peace of mind alone, but it can also save you up to 20% on your home insurance. The insurance savings will help defray the initial setup costs and subscription costs over time. Locations with higher crime rates also make home security systems a valuable investment, but it ultimately depends on your personal preferences and asset values.
Yes, most states require HVAC technicians to be certified, and for good reason. Hiring an unlicensed HVAC technician could lead to poor quality work, costly future expenses, and potential code violations.
As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification which include:
The owner, principal, or relevant manager passed a criminal background check
Required to have applicable state and local licenses
Maintain an average star rating of 3.0 or better on our network, if they have at least one review
Paying to advertise their services
Meeting any other eligibility criteria required by Angi
Keep in mind licensing is different from certifications. A license is a legal requirement to operate a business, while certifications are voluntary.
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.
