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."

"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."

Heating and Air Conditioning questions, answered by experts

DIY is possible for basic cleaning. Professional services handle advanced maintenance like recharging the refrigerant.

No. HVAC, which stands for heating, ventilation, and air conditioning, includes all of the systems that work together to regulate a building’s temperature and humidity levels. In comparison, air conditioners only provide cooling. You can have an air conditioner as part of your HVAC system, but not all HVAC systems include air conditioners.

Definitely. Both experts and homeowners can attest to the convenience and efficiency of HVAC zoning. Not only does it make every room the perfect temperature—no matter what the temperature is for you—but it also saves energy (and therefore money) in the process. It is a costly up-front investment, but many homeowners agree that it’s worthwhile in the long run, especially if you plan to stay in your home for a while.

While personal preferences widely vary, sleep experts say the best temperature for sleeping is between 60 and 67 degrees Fahrenheit rather than 78. If you do choose to sleep with your AC unit tuned to 78 degrees, you might want to use only a sheet or light blanket rather than a comforter. You might also consider installing a window unit in your bedroom so that you can be cooler in bed without wasting energy cooling the whole house.

After a while, dust, dirt, and other debris accumulates on an AC unit's coils and filters, making it less efficient and spreading allergens and other air pollutants throughout your home. Cleaning your AC unit will keep it running efficiently, minimizing future breakdowns and improving your indoor air quality.
