I've had a good experience with Cobalt heating and cooling. The guys were really friendly and informative. They're also very responsive and on time. They helped me with options to replace my furnace and gave me all the information I needed to find the right solution for my home.

Though I found them through Yelp, Yelp is a horrible company in how they treat businesses, and I want to post this here too for posterity:
After putting off AC Installation for years due to HOA approval bureaucracy among other things, I finally put out a Yelp "project" to get some quotes and finally get it done this year after enduring a week of the heat wave.
Hector instantly reached out and scheduled to come take a look the next morning. He very quickly got the general idea of the project and gave me a quote that night. It was such a great quote (I'd had other companies give quotes this and in previous years) - AND they could come do the installation the same week even though I'm sure there were a ton of people dying to get this kind of work done - so I instantly accepted and canceled the other companies that I had scheduled to come in the next day (earliest for them).
Installation day comes and Hector and Oscar arrive at 8:30am to get started, and blast out work all day in the heat *and* wildfire smoke. Turns out my attic had an unexpected giant plank blocking off the original area to go through, so they quickly solved the issue and routed around it. Installation finished by the end of the work day, even with Hector doing some extra electrical work that I asked if he'd be willing to do (completely separate from the AC installation, and that I'm also thrilled to have done!), and I had full AC blasting just in time for the evening, controlled by the Nest Theromstat I bought off Amazon that he also installed for me.
In the end, Hector and Oscar were fantastic, super laid back, extremely hardworking, respectful of covid (more-so than I was being), very courteous of the interior while doing installation (giant rugs laid out to catch all debris), and also transparent with the installation process throughout the day. I would give 6 stars if I could, and will definitely be contacting them first for any similar work needing to be done in the future.
