Gas furnace replacement

We used Atlas Heating and AC to replace our furnace (and install AC) and had a good experience with them overall, for install and continued maintenance. They are a family owned business based in Oakland. There seem to be multiple HVAC businesses called Atlas, they are the ones located in Oakland. 

My recommendation is to call the following heating and air conditioning companies, make an appointment to look at your situation, have them give you different options and a quote for each one. I have used each one of these companies for different projects and can vouch for their integrity, reliability and very good quality service. The bids will vary but you can not go wrong with the one you choose. Apple Heating 510-530-2423, Atlas Heating 510-893-1393 and Rivera Heating 510-483-4328. 

We had an amazing experience with Energy Solutions. Daniel, the owner, is responsive, and we were very happy with the quality of work. Our furnace went out right before the holidays during a cold snap, and he worked long hours to get us back online before the actual holiday (including replacing a lot of ductwork and creating zones in our multi-story home where none previously existed. He came back a few months later to install an AC unit. He is based in Antioch, but did our work in Oakland.

We replaced our gas furnace a few months back with two Mitsubishi mini-split systems. We interviewed Atlas, Hassler and Air Flow Pros. Atlas dispatched a technician that ran a computer program that determined what size unit we needed for each area of the house.  Hassler sent out a salesperson, that gave us suggestions and offered undersized units, compared to the computer program of Atlas. Though they were similarly priced, the units from Atlas were 25% more powerful. Dealing with Atlas was a dream plus they've been in business forever. Note on Air Flow Pros: they came in 30% cheaper than Atlas and Hassler.  It was a one line contract, leaving us no idea what size unit we were going to get. Communicating with them was a failure. 

We just had our old gas furnace replaced by a ducted heat pump. We got estimates from 3 companies: Hassler, Atlas, and Aarvak. Aarvak clearly knew what they were talking about, but their estimate was very high and their timeline was really long. The Atlas person was very negative about the project, and kept telling me it would never work. He was nice enough, but wasn't very clear about what they'd do when I asked my [well-researched] questions. I had to call twice after waiting a couple of weeks to get them to even send an estimate. It was the lowest, but we had already decided we weren't going to get the best work out of them. Hassler knew what they were talking about, answered all of my questions, and sent an estimate in less than a week. They were in the middle cost-wise, so we went with them. It's been a few months now, and the system works beautifully. The work, which was extensive, was fast and very nicely done. 

We got quotes from Gott Watts, Atlas Heating and A-1 Heating. All three quotes were in a similar price range. Each had a slightly different recommendation on equipment, sizing, etc. Atlas and A-1 really stood out in terms of their knowledge, experience and detailed quotes. They are both locally owned and have been in business for a long time, with excellent references. We ended up going with A-1 heating and the installation was a efficient, professional and they were easy to work with. There are a number of good companies, I'd suggest getting as many quotes as you can handle! 

After contacting close to two dozen companies, many of whom don't work with gas furnaces anymore, we were referred to Honrath and Stacey Plumbing and Heating of Richmond. They were flexible, responsive, and came in with a great bid.
