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."

"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."

We are a family-owned company that has been in the spray foam business for over 20 years serving Fresno, Clovis, Bakersfield, Oildale and surrounding areas of Visalia California for many years. Spray polyurethane foam (SPF) is a spray-applied plastic that is widely used to insulate buildings and seal cracks and gaps, making a building or home more energy-efficient and comfortable. SPF insulation is known to resist heat transfer extremely well, and it offers a highly effective solution in reducing unwanted air infiltration through cracks, seams, and joints.Attic Spray Foam Insulation Did you know you could be losing up to 40% of your homes energy through the attic alone?! Using Spray Foam Insulation in your Attic is the only solution you should be considering to remedy your attic’s insulation needs. The attic is the part of the house which is easily over looked, but it is also the part of the home that is most susceptible to the external temperature changes. If you attic is not properly insulated it can lead to huge amounts of energy loss and the fluctuation of the temperature within your home. Proper attic spray foam insulation serves as the key to limit and control the effect of the external temperatures on your homes interior environment, monthly energy bills and energy loss.

"Rusty Schrader the owner/operator is a life saver and went out of his way to help me. He is very knowledgeable in the business and I highly recommend this company. You won’t find anyone more honest, helpful, and responsive so don’t even bother looking"

Energy Efficiency Auditing questions, answered by experts

While you can perform many routine home maintenance jobs yourself, it’s often a good idea to bring pros in for certain tasks. HVAC maintenance, fireplace and chimney inspections, foundation repairs, and roof inspections and repairs should be handled by professionals who know what to look for and can safely perform repairs. You may also find it helpful to hire a local house cleaning service to help with deep cleaning.

Absolutely! Especially if you have an older home that currently doesn’t have air conditioning where installing ductwork just wouldn't work. No one likes being hot in the warmer months, so if you’re looking to sell your home in the near future, installing a ductless mini-split AC can be a good way to enjoy your home more while you’re in it, boost the return on your sale, and serve as a perk to peak buyers’ interest.

Motion-sensor lights use one watt while on standby and five watts while turned on. They’re usually on for one hour over a 24-hour period, bringing the total wattage to about 28 watts per day. LED lights use around 6.5 to 8 watts while on. If you leave an LED light on all night, with night ranging from 10 to 14 hours, you’re looking at using 65 to 112 watts a night. You can minimally cut your wattage in half by switching to a motion-sensor light.

Replacing a window frame will improve your home’s energy efficiency if the old frame is cracked or damaged in a way that allows unconditioned air from the outside into your living space or if you upgrade to a more energy-efficient window frame material. Aluminum is the least energy-efficient window frame material, followed by vinyl and wood. Fiberglass and composite frames are the most energy-efficient.

Yes, skylights can affect a home’s energy efficiency, either positively or negatively. Properly installed, energy-efficient skylights with Low-E coatings, double glazing, and UV-blocking glass can help regulate indoor temperatures and reduce heating and cooling costs. However, poorly insulated or older skylights can contribute to heat loss in winter and excess heat gain in summer, lowering overall energy efficiency.
