"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."

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."

Red Mountain Heating and Air, Inc is dedicated to providing our customers with the best quality and craftsmanship. We are here to build relationships with our customers and communities and to provide our employees with a great place to work. We look forward to working with you!

"I got bids from a *large* number of installers and Red Mountain gave me the best equipment for the price and did a nice job of it despite a few early teething problems that were resolved quickly and competently. But note that the going price in this area for heat pumps is significantly higher than in other areas of the country - regardless of which installer I let bid on my home. In my opinion, given energy price trends, the environmental impact of heating with gas, and having existing solar power on my home, the benefits of a heat pump outweighs the high price in this area, but YMMV. Think thru your position re: BayREN rebates and the recent federal Inflation Reduction Act rebates carefully to make sure you qualify."

Boiler Repair questions, answered by experts

Yes. Boilers need water to run without overheating, also known as dry firing. If you run it without a sufficient volume of water, either because of a burst pipe or a leak, you run the risk of damaging your machine or jeopardizing the safety of your home as a whole. When in doubt, shut off your boiler and repair any plumbing issues before turning it back on. Alternatively, consider installing a low-water cutoff (LWCO) before any issues arise. This gadget will protect your boiler by monitoring water levels and automatically shutting it off if it gets too low. 

One of the most common signs you’re dealing with a bad thermocouple is the pilot light for the water heater will continuously go out. For example, you may light the pilot light and then have to re-light it a few days later. You can also look at the thermocouple for a visual inspection. If you notice discoloration, cracks, holes, or other damage, then you know it needs replacing.

It can be difficult to determine the cause of a coolant leak unless you have the unit inspected by a certified professional. Most coolant leaks are caused by wear and tear on seals and joints. This typically happens five years after a unit is installed. Additionally, faulty or worn compressors, evaporator coils, and condenser coils can also cause leaks.

A poorly maintained boiler can lead to serious issues like deadly carbon monoxide poisoning, so schedule regular maintenance services. Of course, it’s also a good idea to check your carbon monoxide detectors in your home to make sure they’re working properly. Moreover, when you forget to maintain your boiler, small problems can lead to something much more serious, which will cost you more money in the long run. Repairs average around $400, while a full replacement can total over $6,000.

Repair costs range from $200 to $800, depending on the issue and required parts.
