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."

"I was given a fair quote for an on-demand water heater. The 2 other companies were either, way overpriced or were charging sales tax on their labor. The project was done in a timely manner. Dave was polite and professional. I wish the clean-up of sediment from the old standard water heater had been cleaned up. It was left for me."

They had multiple call offs and the person that was working . They would not stay whole day . There was days will he come at 9am and left 12nn and stated that how will needed to work other job site. and he wouldn't be at our work site a whole day and complain already multiple times to the project manager Justin rowe. We keep reminding them to put a shoes to protect our floors and we paid so much for the floor and the labor . They had a gasps in the baseboard and everything and already paid 5000 and its original charge 7200 but we thought we had hire a professional work done but we had hire somebody else to fix the job and we paid a lot of money thinking this was the trust worthy company but we took advantage and Justin cared about collecting my husband and needed a check to get the month quota and the job was not done and we are disappointed and we spend a lot of money for this project.

Install Boiler questions, answered by experts

If you have a closed-system boiler that needs an expansion tank to work, you cannot run your boiler without it (not without the risk of extensive damage and even explosions). Your options include moving the boiler to another spot, rerouting boiler piping to a more open area, or completing a remodel around the boiler to create more space for the tank.

It costs homeowners between $5,000 and $12,500 to install a new HVAC system. This number varies, as each home has its own heating and cooling needs. Even a home with the same footage and number of occupants will have different HVAC requirements based on the number of windows, the climate, and how often the occupants use the system. 

Always consult your manual for specific pressure numbers. Many expansion tanks come pre-pressurized at a specific PSI range, anywhere from 12 to 40 PSI, designed for a range of home boilers. You should not have to pressurize an expansion tank yourself, only the boiler system. If your system has a tank that needs to be manually pressurized, this is generally a job for professionals and their tools.

The best time of the year to replace your HVAC system is during the off-season, which is spring or fall. You can expect HVAC technicians to be very busy dealing with repairs and system replacements during the summer and winter. In addition, purchasing a new HVAC during the off-season will allow you to shop around, find the best deal, and find even more cost-saving incentives.

The average house radiator has a life span of around 10 to 15 years. However, if you keep up with maintenance, such as bleeding the radiator once per year and removing any signs of rust as needed, your radiator may last 15 to 20 years. Consider hiring a pro to inspect your radiators annually to keep them in the best condition possible.
