Michael (the owner) responded immediately to our request for service in Mountain House after our heat stopped working. He showed up the same day and immediately diagnosed and repaired the issue. He could have upsold me on replacing expensive parts, but he is super honest and clear about what was needed and just fixed the issue. I appreciated his transparency and honesty and I'll definitely be returning to him for any future HVAC work! Having someone knowledgeable and quick to respond saved me and my family from a cold night. Thank you! read more

I was connected to Michael through a trusted mutual contact to help with a client of mine who needed a new A/C unit. Michael was able to explain why the A/C unit was running poorly and was able to give use basic options as well as ways to upgrade the A/C system to make it run more efficiently. Ultimately, my clients decided to do a couple upgrades to make the life of the new system last longer. Michael was able to complete all the necessary work for the install in one day and made the process seemless for me, my clients, and their tenants. I would work with him again in a heartbeat and in fact I did hire him for another job where a different client needed some maintenance done on their A/C unit. read more

This company is without a doubt the most honest HVAC company in the entire east Bay Area and beyond. Their prices are very fair. They take the time to explain what new HVAC solution would meet your needs and preferences, instead of upselling like most companies do. The quality of their system installation was above and beyond! It looks amazing! This is the only company I trust, and the only company I will ever be calling to install or work on my HVAC system. read more

Heat pumps are complicated machines. Unfortunately, the HVAC industry is filled with people who just want to rip you off. You'll have a loose wire on your thermostat and they'll try to sell you a new HVAC unit for $12k. Or you'll get someone who doesn't understand how they work in the first place. Michael D'Angelo is your way out. The guy knows his stuff. How do I know? Because after getting strung along for weeks with my aged HVAC unit, after getting over charged and jerked around, Michael came and really REALLY studied the problem. He called the manufacturer for my unit, did a ton of research, came back over and over until he found the problem (a stuck metering device and a badly installed, damaged pipe). He did surgery on the unit, got a specialist welder to work with him, and got a brand new pipe installed to replace the damaged one inside the unit. It was like watching a couple of brilliant surgeons at work. You couldn't ask for a nicer, more conscientious, better informed, more honest guy to work on your system. Whether you run an office, or a factory, or it's for your home or condo, Mike is your HVAC guy. I was so happy with his work I even made him a present. Pic attached (that's the bad pipe he removed and sucessfully replaced). read more

D'Angelo Heating And Air Conditioning - The pipe Mike surgically removed and replaced in my HVAC. I made it into a 'thank you' gift! - Heating & Air Conditioning/HVAC Near Me - Tracy, California

I am super impressed by Michael's professionalism. My renter noticed a burnt rubber smell blowing out when she had the heater turned on. I called Michael on Monday and he came to her rescue the very next day and arrived promptly(5 mins beforehand)as promised. He diagnosed the problem within 10 mins and called me with the solution. He explained everything in detailed to me over the phone and gave me a quote. He even performed some extra work to ensure that the system would run smoothly. Very honest in his pricing and not pushy or try to sell me something that I don't need. He took some before and after pictures and sent them via text message. He was nice, very communicative and efficient- per my tenant. Very detailed oriented and good at following up. Anything HVAC problem, he is definitely your guy. read more

My AC went out on one of the HOTTEST days of the summer and I was in a panic! The home warranty company my landlord had me call came out and refilled the coolant and said it should be good to go.... It wasn't. I was so thankful to find Mike!!! He came and checked the system and said the last tech totally overfilled the coolant and he drained a lot of it. He went up into my attic and found out the main culprit (totally forgot what the part was that he needed), fixed it right up and my AC was blasting ice cold again!! Mike is knowledgeable, fast and fairly priced! Highly recommend! read more

I had a issue with my HVAC system not having a (C) common wire with the correct voltage of 24v to power two nest thermostats in my home. My home has dual zones up and downstairs. The thermostats kept giving errors and my system wouldn't work. I called another company and they came to check my setup in the attic and after seeing the age of my system they told me they couldn't help me and that they don't know how to provide proper power to the common wire from the zone board. I almost gave up but I called D'Angelo and was connected to Michael. Michael right away knew exactly what i was talking about. Without even seeing my system he knew how to wire it and fix the issue. Michael came and gave such great service. Helped me understand my system and worked meticulously one wiring my system and getting each thermostat zone common wire the correctly 24v needed to power the Nest thermostat 3rd and 4th gen. I could not be happier being able to control my system now remotely. I recommend D'Angelo heating and air for everything. Thank you so much Michael seriously. read more

Very humble and honest and quality work. Mike is quick to respond and provides you with knowledge to allow (not push you), into moving forward with decisions. Thanks for coming to the rescue everytime! read more

My thermostat showed "system off". A friend tried to work on it almost all day and it turned out that furnace was fine and it was a thermostat problem. My son bought a goggle Smart thermostat to replace the old one. Unfortunately, it wasn't communicating with the furnace. Michael had to do some rewiring but had it working in no time. This was also a Sunday night and even charged me reasonably. He is very professional and thorough with his work. I highly recommend him. read more

My AC needed some work and Mike came out as soon as he could to take a look and it ended up being my condesation pumps. He serviced my AC heads and changed my attic fan...and now everything is working smoothly and the price was very reasonable. I would definitely use this service again before summer months or maintenance is needed. read more

We called three companies in which none of them could come out until the next day. I have three little kids, one with special needs. We called DAngelo Heating and Air Conditioning, and they sent out a technician who showed up within an hour. He got our heater working in 30 minutes. The technician Jairo was very knowledgeable and checked all my carbon monoxide detectors. He went above and beyond and was very professional. I highly recommend DAngelo Heating and Air Conditioning!! read more
