Get matched with top heating and air conditioning pros in Hayward, CA

"Of all the people I've had work on my home renovation in the last year, these guys were my favorite. Prompt, professional, honest, and reliable. When Duke came to give us the estimate, my 2 year old daughter wanted to give him a hug before he left which is unprecedented. That pretty much sealed the deal for us. They were also far and away the most reasonable quote we got. Even a friend quoted us $1500 more for less work. The installers were on time and knew their stuff. The install work is top notch as well. Everything in place and looks well put together. I highly recommend them to anyone looking for HVAC work."

"Global Comfort installed a full HVAC system in my home; 7 new runs for air, new AC unit, new furnace and a new Nest thermostat, all electrical needs. Rudy and his team are respectful, efficient, punctual, competitive in pricing. Rudy walked me through running the system for its first time and explained all the stuff for a brand new system in a house that never had AC. I'm very thankful for the work they did. Highly recommend because their customer service is top notch."

"Air Sharks are very professional and I think they did a good job on installing HP HVAC in our property."

"Air conditioner was blowing ambient air only. Tried to contact my usual HVAC company and they were scheduled out 3 weeks because of the recent heat wave. I called 14 companies to check on availability and Comfort Energy was the only one who had an opening within the week. I confirmed with them and was very pleasantly surprised. They confirmed not only the day and time, but also the exact make, model, ans serial number of the unit to ensure they had all the information they needed. In the meantime, my husband was able to get the unit going by installing a new capacitor himself, which he had done in the past, but wanted to go ahead with the service call so we could have the whole system checked out in case there were other issues. The day before the appointment, I received a text confirming the appointment time. I asked that the service technician call 30 minutes before arrival, which he did. The technician, Nasser Pineda, is a fine representative for his company. He was polite, respectful of both my husband and me, and took time at the start of the service call to go over what he would be doing and how he hoped to provide us with the best service we had ever had. He said that the goal of Comfort Energy was to provide us with service above and beyond expectations. He did not fail us. He even wore booties so that he did not track dirt into the house. My husband followed him around asking questions and he was patient and knowledgeable. Nasser also told us about their yearly service plan which would ensure service checkups before the heat of the summer and for the heater before winter cold months. That, plus the guarantee that we would get priority appointment times even during heavy demand, has clinched our participation. Nasser and Comfort Energy know how to do it right; ensure that the client doesn't want to go anywhere else for their HVAC service."

"The first week of December we came home to a cold house. The thermostat was working, we could hear the furnace come on but no heat. We contacted Gas and Electric thinking the pilot had gone out. The technician came out and checked the furnace and the pilot was fine but the HSI had burnt out. He explained this part has about a 5 year lifespan. He let us know the part was roughly $25 to $50 and it would take about 15 minutes to change out - a very easy DIY job. We decided to have an HVAC technician come out as the furnace had not been serviced in  a couple of years. We called around to a couple of places  from the list and the quickest appointment was with Albert Nahman Heating and Plumbing. The tech was prompt and professional. He asked where the furnace was located and we explained  it was under the house and due to the recent rains it was a little damp under there. We explained that while we had a sump pump it was a little muddy in the entryway. He said no problem and grabbed a shovel and cleared the mud away and then went to work on the furnace.. He tested the furnace to make sure it really was just the HSI. He replaced the part and had us test the furnace turning on and off the thermostat a couple of times while he was there to make sure everything was working properly. He did let us know that it would be a good idea to schedule a complete cleaning of the furnace and ducts. He showed us the dust etc that was collecting and explained how that will shorten the lifespan of the parts.  The tech was fantastic. The only downside was the pricing. The $50 part was $325. If you are someone who is not good at DIY/ doesn't relish going into crawl spaces or under the house and needs a technician who will explain how everything works and what they need to do as well as what they recommend for future maintenance, then Albert Nahman Heating and Plumbing is reliable.
