Atlas Heating & Air Conditioning Atlas Heating and Air Conditioning is one of California's oldest and most respected heating and air conditioning companies. Eric was extremely thoughtful, professional and helpful. I needed to know a few basic things about how the settings for Heat and Air-conditioning and the FAN work in order to program our thermostat correctly. Though our landlords probably do not use Atlas and I am not a current Atlas Customer, Eric took 5-10 minutes to talk with me and answered ALL my questions. He saved the day - he was very knowledgeable and explained things in a clear concise way.

You can rely on Atlas Heating and Air Conditioning to provide highly knowledgeable service and repair. Our team of eight technicians averages 13.4 years of experience and is one of the largest independent service departments in the Bay Area.
I have a multiple story home and in the summer it is always hot on the top floor but cool on the lower floor. Can anything be done to correct this problem? Heat rises and the top floor will always be warmer. Your thermostat is usually on the main floor, and when that area reaches temperature the thermostat shuts off the equipment, whether or not the other floors are the same temperature.

I learned about Atlas from online research as well as trusted friends that had work done on their homes. I was going to be very particular given the investment of the project. Word of mouth was absolutely on point here. I was incredibly happy with the work done on my heat pump install. Atlas has an incredibly responsive team from their professional office managers to knowledgeable project manager and finally the key piece to me: the installation crew.

My home is on a steep slope, with a long narrow staircase leading to the yard, and it has a small crawl space. This wasn't going to be an easy install. But they made it work and were thoughtful with the uniqueness of the space. Nick Reno did our initial assessment and assured us he's seen all types of configurations and would treat my home like his own and considered aesthetics along with the nut and bolts.

They were respectful of covid protocols without me having to ask. They also left the work site spotless. Re cost: Atlas was comparable to the other bid I received. What tipped my decision to go with them was their warm professionalism and attention to detail. Would definitely recommend them to family and friends.

I had a very positive experience with this company commencing with the person I spoke with on the phone. She was empathetic and was able to schedule a speedy appointment. The technician who came to the house was extremely competent and knowledgeable. He readily identified the problem, had the needed part, and was able to quickly resolve the issue. I haven't had any subsequent problems. I highly recommend this company.

Our 35-year-old heater gave up the ghost and because Atlas had installed it, we asked them to come see what was the issue. It had developed a terminal problem that was making it dangerous as well to continue using it. The technician showed us what had broken and in no uncertain terms let us know we needed to replace it. This was during a pretty tough cold snap, so we were in a bind, disappointed, and freezing.

But I never once doubted the sincerity and truth of their diagnosis and despite the fact that the time estimated for replacement seemed long at first, it was clear to us that they were doing the 'right thing' in terms of procuring and installing the machine. And it was also became clear to us that heaters are now very complex entities with lots of computer aided functions. Atlas came when they said they would and quickly (at least to me) installed the new heater. BUT IT WOULD NOT 'fire up' and had the initial team baffled as to the cause.

To make this long story shorter, it turned out that a computer board part was failing. Then, to all of our dismay, the replacement was also defective and we were still freezing. Ultimately, they were inventive enough to simply 'borrow' the part from another heater in their inventory--putting the customer first. I do not know anything about this crucial appliance in our house, but i never had any indication of hesitancy or remorse or dishonesty regarding their efforts to solve our problem. Needless to say, the appliance was expensive, but our money was well-spent and i give the highest of recommendation for you to use Atlas should you have a similar issue.

The heating system in our attic was leaking water onto a bedroom ceiling. Atlas came out, found the solution, and took care of it right away. They were timely, professional, and very helpful. Service: Repair HVAC

Our furnace stopped working completely, out of the blue. After doing all the self-diagnostic stuff I could find without getting any results, we called Atlas. Chris came out the next day, traced the problem to a loose wire in the thermostat & had the heat back on within 30 min. Added their card to the 'call these guys first' hall of fame list.

We've used Atlas for *many* years to maintain our gravity heating system (from the 1930s). Their techs are knowledgeable, on time, and extremely responsive. On the one occasion where we had a problem, it was dealt with promptly. Highly recommend. Service: Heating system maintenance

A couple of days before Christmas some trees fell on the power lines and broke numerous power poles and transformers exploded. The power surge to the house tripped the outside and inside circuit breakers. Unfortunately the fuse, switch and transformer on my furnace did not survive. I contacted via yelp, a few of the suggested vendors. It being a holiday most of them could not help me for at least a week or more. Atlas was able to come within a couple of days of my initial request.

The tech was straight forward and upfront about the costs and problems. As with all emergencies it was a reasonable convenience cost versus trying DIY it, especially with the the super cold weather we were having at the time. I would recommend them.

With no heat on a Saturday, Atlas took the call and showed up within a few hours. The tech found the problem in about one minute, discovered what caused the problem, and then repaired the heater. Quite impressed with the skill of the technician. Service: Heating system repair

We had such a great experience with both our technician (Aaron) and the office staff at Atlas. Our heater stopped working after Thanksgiving and they were quick to send Aaron out to take a look - he did a great job of explaining what was going on with our older heater and talking us through our options. He was both optimistic and realistic, which helped us make the best decision for us re: how to move forward.

Once the part he needed came in, Atlas put us back on his schedule ASAP (much appreciated since we are due with our first baby any day now). Our heat is back - just in time! - and we look forward to working with Aaron & Atlas for all of our needs going forward.

Just when the mercury started to drop for the holiday season our furnace went on the fritz (again). Last February I had similar issues with the furnace and Atlas performed the repairs. This time they responded to my service call and had a technician out the same day. Ray was awesome. He was courteous and professional and identified the root cause (wiring of our Nest Thermostat).

He called the office and explained the repeat issue and got Atlas to wave the repair charges due to incomplete solution on the previous service call. I was very pleased all around.

Besides repairing my ducts, Nick Reno went above and beyond to remove a large, mummified opossum from my crawl space that no other company had. We assume that that poor animal had ripped the ducts while attempting to exit from under the house. I highly recommend this company.

Our furnace went out at the start of predicted cold weather and the Thanksgiving Holiday. I contacted Atlas because of their reputation and longevity in the business. An appointment was scheduled within a few days and Technician Raymond Corral (#89) appeared promptly as scheduled. Raymond ran diagnostic tests which pinpointed the problem. Parts were ordered and installed.

Unfortunately we had additional problems and with a quick call to the office, Raymond appeared and diagnosed the new problem. New parts were installed and the problem solved! Raymond was professional, prompt, patient and comfortable in explaining his actions and what needed to be done. His professionalism and expertise were greatly appreciated. I also would like to mention Leila, who answered our calls and understood the problem of having no heat. Leila was extremely helpful and understanding.

I have absolutely no hesitation in recommending Atlas Heating and Air Conditioning Company. The company has been around for quite some time and their service and commitment to the customer is why they have lasted.

Really great service that you can trust. I was worried not knowing much about HVAC that I might get taken advantage of, but not with Atlas. They were very honest and looked for the reasonable solution that didn't break the bank. The service was quick, and the technician was great. I highly recommend giving them a call if you're in need.

Atlas put in three air conditioning wall units in our house. They all work well. However, this shout out is about their customer service. Unfortunately, one of the units was not sealed correctly initially and, during a storm, a bunch of rain come in and destroyed our carpet. Atlas agreed to pay for half the cost of our carpet replacement (it was already several years old). Even though we waited a bit to get them an invoice, Atlas made good on its promise.

We did an over two year restoration and remodel of our home. Atlas was our HVAC contractor for our heating and cooling. They designed, engineered, fabricated and reworked our entire heating system for better performance. Two zones were created for better energy usage. Then air conditioning was installed. All of the work is perfect and they balanced the system for maximum efficiency. Beautiful work. I highly recommend Atlas to anyone. They should always be your first call.

I requested service for our A/C, received an appt in a couple of days. Their technician Chris, came out to assess why the unit was not producing cold air. He quickly determined the issue, explained what was required and provided a quote which was based on the amount of coolant needed. Chris was professional, knowledgeable and provided tips on how to check the filters and how to keep them clean.

He arrived on time and worked efficiently. He was thorough and based on his service alone, I would have no hesitation in calling Atlas again should I need my heater or A/c serviced again.

We purchased our Trane A/C unit from Atlas 23 years ago. It's running fine, but wanted to have it serviced to make sure it's in good working order for the summer. Worker Casey called to let us know he was on his way, showed up when he said he would, and was very respectful of our home. He efficiently serviced our unit and was able to work around difficult access to the unit. Fortunately, our unit is in good working order now. When we need a new unit, we will definitely call Atlas!

We have a Fujitsu heat pump that had been improperly installed by another company. We'd tolerated substandard performance for ages until Ian from Atlas came to fix our furnace and also checked out the heat pump. He did a wonderful job and we now have functioning heat and AC in our attic bedroom. We are irrationally happy.

Had a perfect service call from Atlas. Their technician John was thorough, on time, left the site spotless and had great communication skills. He answered all my questions and talked to me about what to expect in the future. I manage a handful properties and frequently deal with service providers and this was one of my best experiences. The furnace is a monster, old "gravity" style from 1950 and Atlas has managed to keep it safely humming along. Very happy customer.

This company is great, from the folks that answer the phones to the furnace experts that come to your house and make it warm again after it's been so cold. They are professional, timely and smart. I will continue to use them and would recommend them.

Atlas Heating is fantastic, reliable, fair pricing, great service and products. During January 2021 we had a flood that damaged our furnace in my mother's home. The team at Atlas was able to fix it when another provider could not. I can't recall the service technician but he was GREAT. I also have worked with Ian who came back to replace a part in-continued service to my mother's home. Additionally, last year, I used Atlas to replace my furnace and add AC.

Everything from quote to install was excellent service. And, I have to say I love AC. Growing up here in Oakland we relied on the fog but now heat waves are more frequent. I highly recommend AC if you can fit it into your budget. I would call Atlas first for all your HVAC needs.

I'm updating my review because the owner of the company saw my review and called to apologize for our poor service. She explained that they do service houses with crawlspaces, but that recently they'd had 2 workers injure their backs, so they had to be extra careful about working in small crawlspaces. She apologized that their reps hadn't explained that our crawlspace might be an issue and offered to have someone come back and measure the space, but we'd just signed a contract with another company.

This one is long overdue. I'm own an HVAC business that specializes in air the air quality aspect of the trade. Since I started my business, I've seen thousands of HVAC setups. I know a thing or two about HVAC system design, and I must say that by far, Atlas Heating's (of Oakland) installations are the most elegantly (and mechanically) designed heating and air conditioning systems. I've seen new companies pop up like mushrooms in the last decade.

The problem is that HVAC installations are one of those things where the typical homeowner has no way to compare apples to apples. A poorly designed system may look shiny and pretty yet add tens of thousands of dollars in unnecessary operating expenses (waisted energy due to high static pressure/resistance, and frequent repairs). I've seen some of the most reputable companies in the east bay (reputable on Yelp anyway) provide amateur level installations, yet every time I pulled out a manometer and tested a system that was installed by Atlas, the result was perfect.

Their prices are definitely not on the lower end of the spectrum (nor the highest), but their installations offer the best value out of all contractors in the area (excluding commercial HVAC contractors. Commercial HVAC energy codes are far more strict than residential codes). I highly recommend Atlas.

Atlas has been my go-to HVAC company fr more than two decades. So when my system failed during the first brutal heat wave this year, I went to them immediately. Everyone involved, on-site and in the office, was wonderfully responsive and patient when I needed some explanations. The new system works perfectly and will bring down my PG&E bill.

We had probably 6 different estimators come out and give us a quote. Atlas was very thorough and our estimator Jason had very quick response time for any questions we had. Team was fast efficient with the work, did exactly what they quoted us for (more than expected honestly!) and walked us through everything including our local union rebate. Pricing was fair and they got us in just in time before the winter. Hope to use them again in the future and highly recommend.

Atlas was referred to me by a neighbor and I'm glad I called! They were able to get out a few days after my initial call. The technician was extremely friendly, looked into every issue it could have been, and was able to diagnose the problem and fix it same day. No funny stuff, no games. Last company I called out tried to overcharge me because I lived in the hills and apparently also overflowed my freon. I'm so happy I went with a recommendation instead of winging it. I'll definitely use Atlas again. Reliable service is hard to find!

After 33 years our heater has some issues that needed some professional evaluation and repair. Aaron came in and made some assessments based on our current issue and the wear and tear of our existing unit. He gave us a great explanation on what the pros and cons are if we repair it or do a complete replacement. Given its been 33 years we decided to go with the full replacement.

We are currently schedule for October installation but Aaron also let the main office know that we don't have heat at this time, which might give us an early installation (crossing our fingers). We will update our review after our brand new heater has been installed. My heater replacement was initially scheduled for Oct 11 but they actually came thru for us and got my heater heater installed couple a days early which was on Oct 7, which is perfect.

They were prompt in showing up on time and Joe did a great job in installing our heater. He spent quality time with us in explaining the how to and features of our new heater. He kept us informed on his installation progress at all time and did a great job as well is cleaning up after himself. I strongly highly recommend this company to anyone who wants to have their heater replaced or repaired.again thank you so much for memorable great service by their staff and this company. A great asset to the Bay Area community and top notch company!
