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."

"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."

"Vincent and his assistant Sergei took on a difficult job of installing a stove top and a downdraft fan that posed some challenges of fitting into an existing counter space. An installer sent by the dealer failed at this task but they were careful and creative in finding solutions. We appreciated the attention to detail and their hard work - and the result was fabulous. Not least, the price was reasonable and both of them were easy and pleasant to work with. No hesitation in recommending their services."

"Had them out about 7 months ago to replace insides of my dryer as it was not working. Thought they did the job as our dryer worked. Then two days later the credit card I used to pay them had several unauthorized charges on it. Now 7 months later my dryer needs to be fixed again, with all of the rollers replaced, which is what they said they did 7 months ago. They are crooks. DO NOT USE THIS COMPANY."

Energy Efficiency Auditing questions, answered by experts

If your AC runs constantly, it could be due to a number of things, including a faulty thermostat, incorrect temperature settings, or broken equipment. Alternatively, you might have an airflow problem (for example, blocked vents or leaky ductwork). Either way, an HVAC pro can identify the specific problem and fix it for you.

When combined with a substantial solar system, if you have enough Powerwalls, you could go off-grid and be energy independent. But remember, you'd need enough Powerwalls to power your whole home continuously because a single Powerwall can’t power large appliances for extended periods. One Powerwall is able to power an average-sized home's emergency circuits, lights, and outlets. To power large appliances, you likely need two or three Powerwalls.

Costs depend on pipe length, accessibility, and whether additional services are required.

An average, 400-square-foot electric heated driveways consume approximately $3 per hour in terms of electricity. The price may slightly fluctuate depending on your local energy cost. A simple formula to calculate your heated driveway’s total wattage consumption is by multiplying the square footage by 50 watts and then dividing it by 1,000 to get the kilowatt number. Multiply that with your local energy cost per hour and there you have the hourly operating cost.

String lights require electricity, but not an excessive amount, especially when compared to other lighting fixtures. LED rope lights, for instance, consume around one watt per foot. Running six or seven light strings simultaneously should only cost you around $10 to $15 each month. You can save even more money by remembering to turn off your lights during daylight hours.
