"Very knowledgeable. Originally our new wall oven would not work due to some issues with the electrical. Brian Hamilton was able to converse with the oven installers and get the oven working. I highly recommend Hamilton Electric and would use them again. While on site Brian also replaced a wall switch that regulates the light, exhaust fan and heat. In the past people have had to cut through the outside hallway wall to have room to replace the switch. and than plaster the hallway wall. Brian replaced that switch in less than 15 minutes."

Albert Nahman Services was founded in 1981 and has been serving Berkeley, CA and it surrounding areas in all their plumbing and HVAC needs. Each of our technicians went through rigorous training so we can guarantee that you will be receiving the proper service. We are also insured and supply a warranty for our parts for five years and up to twenty years on an re-piping or sewer replacement. Call us now to make your appointment!

"The plumbing technicians came out as promised to assess the leak. They were both very courteous and kind and assessed the damage. I am giving three stars because they estimated the cost to be almost 250% higher than what the actual cost was to fix the issue. I am sure there are customers out there that would just accept any bid however, please get multiple beds for these projects, especially when working with this company as they will inflate the cost to take advantage of the situation. I ended up only paying for the $79 estimate."

"Did a $59 consult only. Turned out the cost of repairing the old heater was almost as much as a new one, so we got a new one, and handled the install ourselves. Luis B was great, knowledgeable, friendly, didn't try to upcharge just to sell a heater, which we appreciated. Gave us an honest evaluation, several options, and was right on time. I will say, though, that the company failed to call me when he was on his way... not a big deal. All in all a good experience."

Bonney Plumbing, Sewer, Electrical, Heating and Air, has been your local, reliable service company since 1978. As an A+ rated member of the Better Business Bureau, we have worked hard to build our reputation by providing you with top notch technicians, superior products and exceptional customer service. We have serviced thousands upon thousands of satisfied, loyal customers and are so pleased to earn your referrals. You can count on Bonney for quick, reliable service and repair for your plumbing, electrical, heating and air conditioning needs.

"For starters, most of the people that came out to do the actual work were fine. My issue is that I have been waiting since the beginning of 2024 for a response on being overcharged for a duct run that was never completed as part of a nearly $20,000 project, despite several emails, phone calls, notes left on the account, etc. This is even including talking to someone on the phone who still calls me to set up yearly inspections as part of our Bonney Club membership. Not only that, but we have recently found evidence of mice in the house and in looking around the HVAC closet (which is within the conditioned living area and where mice have been) I was surprised to see that they left the ceiling of that closet wide open to the unconditioned attic space. No wire mesh (as was there before with insulation on top), no sheet metal (which was liberally used everywhere else, even to patch a drywall hole instead of using drywall), and certainly no insulation to replace what was there previously."

Solar Panels questions, answered by experts

Solar roofing shingles may qualify for significant federal tax incentives through programs like the Residential Clean Energy Credit, which offers up to 30% of installation costs through 2032. State and local governments often provide additional credits, and utility companies may offer further rebates or net metering programs, depending on the state. Just look into the qualification requirements beforehand because installation, documentation, and technical standards can impact eligibility. Consult the current guidelines and a tax professional to maximize available benefits.

If you’re deciding between a solar battery versus a generator for the best backup power solution, you can take a few factors into consideration. Solar batteries are quiet while generators can be quite loud. Generators have a lower up-front cost, but they require fuel and ongoing maintenance while solar batteries are more expensive but don’t have many ongoing costs.

Yes, you can connect an inverter directly to your solar panels without solar battery storage if your home is connected to the power grid. However, most pros don’t recommend a direct connection because solar panels don’t put out steady voltage. It’s always best to install a charge controller between your solar panel and your inverter to regulate the flow of energy and ensure a stable power supply.

As long as your solar panels are properly installed without damage to your roof, they will not shorten the roof’s life span. Solar panels can act as a cover or barrier to your roof and help block external elements, such as debris, heat, and UV rays. Reduced exposure to the weather can extend your roof’s life.

Solar water heating systems are not one-size-fits-all. You'll likely work with a team of experts to get the job done—including solar panel installers, plumbers, and water heater installers. A specialist will help you decide if a passive or active system is best for your local weather, home layout, roof stability, and your budget.
