Their work looks like a mechanical piece of art, which completely surprised me. They are prompt, neat and dependable, just a pleasure to work with. So glad we went with California Plumbing & Radiant Heating and we highly recommend them.

OMG, Gerald is SO knowledgeable about residential boilers and heat pumps! He is super familiar with…read moreour old Munchkin boiler, that he kept a graveyard of them as a source of parts for the now-discontinued product. He was very responsive to our no-heat, no-hot-water situation and made room in his schedule to get it fixed right away. He knew why the boiler had failed and what was needed to prevent it from failing again. He charged less for the whole job than another contractor was going to charge just for the parts. As well we discussed heat pumps, and he was fully aware of what would need to be changed with our system to use a heat pump instead of a gas boiler. The guy knows his stuff, is responsible, and is a straight shooter. He saved us from out boiler outage quickly, and we have found our guy to install a heat pump. I could not recommend him more.

Called to repair my friend's refrigerator at a dumpling restaurant in Vallejo. Richard sent a…read moretechnician next day who spent over 1 hour but couldn't get the unit repaired. Richard quoted on the phone $200 for diagnosis and $50 for transportation, then the technician charged "equipment fee" for measuring the freon pressure. My friend paid $450 without getting the refrigerator repaired. He had to hired another technician who correctly diagnosed a freon leak and made the repair. Do NOT bother with this business, totally dishonest and incompetent.

Though there are limited HVAC services to choose from, this is not one I would choose ever again…read more To start, the name "On Time" is a joke because of the many times he came to service our walk-in cooler, he was on time once. Richard is often rude on the phone and claims to know more than the health department. He left our commercial hood barely drawing air saying it was the best it was capable of. We just had another technician come and simply "turn up the power". At least his assistant is very nice!

I don't leave reviews very often, but Jonathan definitely earned this one. He installed a brand new…read moreGoodman HVAC system at my home in Brentwood, CA 94513, and the whole experiance was smooth from start to finish. He was on time, honest, answered all my questions, and never tried to upsell me. The installation came out super clean, and you can tell he really cares about the quality of his work. If you're looking for a reliable HVAC contractor for a new AC installation, air conditioning replacement, heating and cooling system, or furnace installation in Brentwood, I highly recomend Jobon Heating and Air Conditioning. Fair pricing, great communication, and excelent workmanship. My new Goodman system is running perfect, and I wouldn't hesitate to call Jonathan again or recomend him to my family, friends, and neighbors. Five stars all the way.

STAY FAR AWAY from Jobon Heating and Air Conditioning. Their techs are unskilled and took several…read moretrips to our place to attempt to fix a simple mini split which is still unresolved. They were hard to track down when we tried to reach out (every time) and the people that showed up were clueless and always calling others for support where they didn't have the appropriate experience. Jonathan said the unit was wired incorrectly by his team (a person he has since fired) and then it was a coolant leak and now we're enduring another heat wave with NO RESPONSE, NO SUPPORT. Further, this install was on the properly of an elderly woman where Jonathan from Jobon basically took advantage and took her money and ran. Jobon could of course replace the whole unit under warranty but they can't seem to figure out how to accomplish that.... Yikes... I think they must be DJing at Burning Man - priorities.

I'm a first time homeowner in my 20s and went through the whole process along with my wife all by…read moreourselves without any help or support (not our choice), so naturally I had to work extra hard to make sure I didn't put us at risk of being taken advantage of or making any critical mistakes along the way. For better or worse, I decided to purchase my own heat pump HVAC system. Little did I know that by doing so, absolutely nobody would even come to the house to entertain installing it for me. Abraham answered my call, told me it was no problem whatsoever and that he and his team would get the job done. They did everything extremely professionally, were very communicative and efficient, and overall brought my wife and I some much-needed ease. Abraham is a very stand-up businessman, he is reasonable in his pricing, very transparent about costs, and has now become my go-to professional for all maintenance and other HVAC-related needs. I highly, highly recommend him. Your money will be well-spent over any of the "big" HVAC names around the bay area, trust me.

We got estimation from at least hvac companies to replace our current heating furnace with new HVAC…read moresystem (most of them have 4.5-5 stars review with diamond certificated). But, we finally chose Santizo HVAC since their price are reasonable & 20% cheaper than the other one. At first, we're worried that it will be difficult to get an approval to install AC since our home is TownHouse and there is no backyard. But, Santizo HVAC supported us a detail document to submit our request to HOA and we got approval with no further request from HOA. The job was done in just 1 day and I was really satisfied with the new AC.

After just typing in water heater on here I saw a lot of plumbing companies but I didn't know a company dedicated to water heaters even existed! They answered all of my questions, came to look at my water heater the same day, SAME DAY and then repaired it for a low price. I hope my water heater doesn't go out anytime soon BUT honestly they have a life long customer because of the awesome service!! Special thanks to John for helping me fix my water heater!!

They really came through for me at the last minute and I truly appreciate that. I was in a total panic when I was trying to bathe my kids and discovered there was absolutely no hot or warm water. It was a pretty depressing situation and I was really worried because it was late afternoon/early evening and didn't think I could find anyone to help me so late in the day. NOW! Water Heaters not only came out that same day (within about an hour) they were able to fix the problem and all for a very reasonable rate! Thanks again guys for your quick response! I would definitely recommend NOW! Water Heaters to anyone who is need of help with their water heater. They are professional, efficient and affordable.

Unfortunately, we didn't know about his company 8 years ago when we had the new system installed. The company that did the installation is now out of business! Lesson Learned.

He's as HONEST as you will ever find. Call them for ALL your Hvac needs...

I called JCS because my heater at home wasn't working. Javier came by the same week and was able to…read morediagnose the problem in 5 minutes. LUCKILY he had the part in his car (igniter was bad) and fixed it on the spot. On top of that, he offered me a free routine maintenance which included a new filter and cleaned coils for the AC.

I hired Luis and his team to do full house insulation work for a full house renovation and…read moreexpansion project. Luis was a pleasure to work with when setting up the job scope and then ironing out the details of the contract. When the job started, his crew were all very courteous and professional. They worked hard and did an excellent job installing the various types of insulation I requested while meeting the Title 24 energy specifications provided by the architect. Highly recommend Luis and his team for any type of insulation work.

The insulation crew finished yesterday and I wanted to give a shout-out to a fantastic job they…read moredid! They were very professional, worked hard, and addressed the minor suggestions that I had. It was a real pleasure to work with them! The job went better than I hoped. They worked with my roofing company. After the roofing company did the tear-off, the insulation company started right away to vacuum out all the old insulation. After all the insulation was removed, they air-sealed all the penetrations (with fire-rated spray foam) and then added a fluffy R38 insulation everywhere. And this was all via the roof, not dragging hoses and insulation through the house to get access to the attic hatch. Much easier for me not to have people going inside our house all day making a mess. The roofing job was delayed for 2 days due to possible rain and they worked directly with Insul Techs to adjust the scheduling, making it all painless and seamless for me. The upshot is great customer service and work.
