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."

"We had broken underground pipes that flooded ours and attached neighbors houses. We have a shared meter, with neighbors having their own shutoff, we did not. After 3 quotes, we felt most confident in Harry. He installed a shutoff valve for us, and now neighbors and us are not dependent on each other’s water. He then isolated and replaced the damaged pipes. He was able to do this without further damage to the house. He came in less than verbal quote and never tried to upsell, which was an issue with one of the other companies. We are very happy with Harry’s work, would highly recommend him."

"Never had such a great experience with any contractor. So grateful to Eugene, Artem, Nick, and Alex not only for the great work they did, but for the care and attention they put in for 3 straight months. My house is built kind of complicatedly and the water heater isn't located in the most accessible place, but they were able to make it work. Not only that, but Eugene found me a new tankless water heater that would also work with my radiant floors - not only saving cost, but space as well. To say they went above and beyond is an understatement. They came back multiple times to make sure work was up to par - never half-assing anything. Really hoping I don't have any reason to need to reach out again soon, but if I do, I know who I'll be calling. Also, special shout out to Jeremy, Karen, and Kathy for their logistical help as well!"

Atlas Heating and Air Conditioning is located in same West Oakland building as it was in 1927. Atlas employs an average of 35 people (seven for 25 + years) and has separate repair/maintenance and installation departments. Residential maintenance agreements and commercial service contracts are popular, also our reminder service. Energy Upgrade and California First (PACE Program) certified. Visa/Mastercard/Discover available, also financing.

"We had a great experience having our furnace replaced with Atlas Heating and Air Conditioning. A different company originally recommended that our furnace be replaced and we got estimates from a total of three companies. Atlas was reasonably priced. The estimator Keith was very responsive and patiently answered a number of questions about various options. He gave frank assessments about what would be involved in a two-stage furnace, higher-efficiency furnace, central A/C in addition, or a heat pump. The installer Joe arrived right on time, worked all day, clearly explained our new thermostat, and left the work area cleaner than he found it. He also patiently answered my questions about maintenance. We're still waiting to complete the permit and MERS inspection but overall we've had a great experience."

Gas Leak Repair questions, answered by experts

Common signs of gas line leaks include a rotten egg smell, hissing sounds, dead plants around the area of the leak, and unexplained physical symptoms like dizziness and nausea. If you notice any of these signs, act immediately. Shut off the gas supply to your home and call a pro to assess the situation.

Almost all new buildings in California need an earthquake shut-off valve. The requirements for an earthquake gas shut-off valve (and who can install it) depend on where you live. For example, according to the Los Angeles Municipal Code, you’re required to hire a licensed contractor to install one whenever you build, sell, or renovate a home. Check with your local building department for your city’s laws on installing, permitting, and inspecting earthquake shut-off valves.

The best sealant for gas pipes is usually a pipe joint compound, or pipe dope. It creates a durable, leak-proof seal that is resistant to high pressure and vibrations, and it doesn’t break down like tape can. Yellow Teflon tape, or PTFE tape, can also be a good option and is a safe and reliable sealant for gas pipes when you or a pro apply it correctly.

Modern gas fireplaces are relatively efficient and don't burn excessive amounts of gas, especially compared to older models. A gas fireplace might use between 10,000 to 40,000 BTUs per hour; the total amount of gas used depends on the fireplace's size, heat output, and how often it's in use. To help keep your running costs down, consider using a thermostat and turning off the fireplace when not needed to minimize gas consumption

As long as a licensed professional installs your gas lines, you don’t have to do anything extra to prepare for cold weather. If there are pipes that require a wrap, your installer should have done it for you already. If you want to be absolutely sure your gas system is good to go for winter, the best option is to schedule a gas line inspection.
