This is the second time I have used John at Core. This time, my heater stopped working. He responded quickly, replaced something, and charged a fair price. He strikes me a a hard working, honest person, who wants to be of service. read more

John came highly recommended and I would now consider no other to repair our heater. He responded immediately and was out to solve our problem. We had fears we'd have to replace our heater, but John used his vast knowledge and quickly figured out what was needed and he had the parts on hand to fix and tune up. Really fast. Honest. Won't oversell. He takes pride in giving his customer the confidence and personal experience that is rare. read more

John came out to inspect my hvac unit, he checked everything, in the attic, all the vents, filters and outdoor unit. John is thorough and explains what he sees which helps me to understand how it works better and what to look for. Very kind, honest, super knowledgeable and reasonably priced. I have used his services for years and would not call anyone else! read more

We have had John to our home twice in 8 years. I was amazed to find such an honest, skilled, dependable HVAC expert. His ethics match what my father taught me many years ago -- so unusual these days. There are so many HVAC companies which don't even TRY to repair AC systems -- they just tell you it has to be replaced (for thousands of dollars). John, unlike his competition, actually diagnoses what is right and wrong about your HVAC. He always prefers repairing instead of replacing; think "savings". In our case, he found a bad condensor in our AC compressor and replaced it, while also, at my request, explaining everything he was doing. He also showed me how to clean the compressor radiator, so I could easily maintain it in the future. His bill was quite reasonable. Although unusual, 4 months later the new condensor failed. John came to our home a few hours later, diagnosed and replaced it at NO CHARGE. Core Heating, Refrigeration & Air Conditioning is the BEST! read more

5-Star Review for John Salus HVAC!! We recently had John Salus come out to repair our air conditioning, and we couldn't be happier with the experience. Not only did he get the system running perfectly again, but the way he approaches his work shows real pride, integrity, and care. What makes John stand out is that he's not just an incredibly skilled HVAC professional -- he's also someone you immediately feel you can trust. He explains things clearly, doesn't push unnecessary work, and treats your home like his own. Beyond the repair itself, it was just a pleasure having him here; he's the kind of person you're genuinely glad to know. It's rare to find someone who combines expertise, honesty, and great service the way John does. For us, he's now the HVAC person we'll call for anything in the future, and we recommend him to anyone looking not just for top-notch heating/AC service, but also for the peace of mind that comes with working with someone of such great character. read more

Great service with a smile Always looking for most cost effective solutions. John is great read more

This is the third time we've called Jon at Core Heating. The last time was five years ago in a different house where he installed a new furnace for us which we were super happy with. Now we're in a new house and he just came out and found the simple problem that was caused by some crazy old electrical confusion here. We have our heat back now that the weather is turning colder! Thank you, John. You are always warm, personable, and I appreciate your depth of experience and the advice you give for a new homeowner. You are the top of my list for who to call. read more

I was referred to John by a friend. I explained my situation and the urgency of the service. Initially I left a VM and I was happy that he called me back the next day. He squeezed his schedule and came out to work on my HVAC. I had a new thermostat installed but it was not wired correctly. John was able to spot that quickly and fixed that. He cleaned up the HVAC unit completely and told me that it never got any maintenance or service for 40 years. He fixed the fan under the staircase. It was a very difficult job as he had to work on the parts/unit upside down with very little space. Then the motor turned out to be dead when we tested it. He replaced a brand new one for me. We both thought it would be a quick fix- at most 2 hours. But it turned out to be a very difficult job with such an old equipment and parts were reaching the end of the life. I'm so happy with the outcome and am really appreciate that John pushed through the challenges and didn't give up. I would recommend to anyone who needs service for HVAC from Core Heating. Thank you, John. read more

Heating broke down and I contacted John. He replied that same day, came over and fixed it, explained everything, and charged me a fair price. Amazing service. Will call again. He is now my A/C service company. read more

I debated on even writing this review because if John gets too busy then he won't have time for little folks like me... but he's as genuine as they come and I want my neighbors to know about him too. Like many other reviews on here, John was the hero who gave my wife and kids heat again without me having to sign my life savings away. John came out during likely one of his busiest weeks when everyone is starting to turn their heaters on and realizing they didn't work. I was told the heater was old and needed to be replaced by other companies in the past and thought my furnace was on it's last legs. His response was, "as long as the core heating elements are still intact I can almost guarantee I can fix it." He fixed it. If you are looking for folks to get quotes from because your heater/AC busted and you are being told it needs to be replaced I highly recommend you call John at Core Heating first. He's authentic, easy to talk to, quick to diagnose problems, and doesn't have a salesman vibe. My house was John's 6th call for the day before 3PM. He's a 1-person, veteran owned business, and someone who takes immense pride in his 30 years of experience. He said he does both residential and commercial properties. He knew the unit in my attic before even seeing it because he lives in my neighborhood and works on all the houses around us. Please call him first before you call other companies for other quotes. He'll likely satisfy your need to make any more calls. John, if you are reading this (and I'm sure you will because you take pride in your work) thank you so much! read more

Incredible service! John was able to quickly fix our thermostat connection & patch an open air vent in the attic. Thoroughly checked our furnace, recommended the correct furnace filter to be using, and fixed our issue of the furnace sporadically turning on/off. 10/10! read more

I trust no one else other than John for our HVAC needs. We have needed his help three times over 10+ years of living in our home. He has always delivered in customer service, knowledge, and quality of work. He is communicative and is very transparent in the work that needs to be done and associated costs. I could not recommend him more to anyone needing the services he offers. read more

Our hot water heater stopped working on a Sunday late afternoon. I called and left a message for John. He called back in 15 minutes and arrived at our house 10 minutes later. He diagnosed our problem, fixed it, gave us a good deal, and resolved the problem. Our hot water was back on within an hour of first having the issue. John's professionalism and expertise were evident, but what stood out was his friendly nature. He offered us reasonable rates, making the entire experience pleasant and stress-free. It is lovely to meet someone who enjoys their work, which translates into excellent customer service. Don't even think of calling someone else if you have air conditioning or hot water heater issues or questions. Thank you, John! Warm regards, Craig. read more

John is amazing! He came in to check the flow of a new AC unit in my home. He could have just charged and checked the vents, but no! That is not John! He cares beyond words...He checked my AC unit installation. He gave me a list of things that needed to be addressed and corrected. He spent a great deal of time in each room and in the Attic. I learned a lot with him and I knew he was going to be my main AC person. I just called him recently to relocate my AC unit for installation of pavers in garden. He came and he did his magic! I am hiring him next to add an AC unit to my garage! I trust John. He is a perfectionist and I trust his expertise, professionalism, and true love for what he does and the people he helps. He is very reasonable and you will be smiling when he works on your project! I highly recommend him read more

Core Heating, Refrigeration & Air Conditioning - Best HVAC Contractor in Petaluma : ) - Heating & Air Conditioning/HVAC Near Me - Petaluma, California

The HVAC Hero Who Saved Our Furnace Johnny, from Core Heating & Air Conditioning, deserves the highest praise for his swift and honest service. When our heating system failed, we called multiple companies, including Bragg, only to be met with questionable practices and exorbitant quotes. Bragg's technician dismantled our furnace, and insisted on a $22,000 replacement with a 9% interest rate. We were even told to replace a new AC system barely two years old. Enter Johnny. He came to our rescue, revealing the scam and fixing our furnace that Bragg's had taken apart. There was nothing wrong with it! He showed us why it kept shutting off - two of our vents were closed. That's it. It was overheating. I've finally gotten around to writing this review 4 months later. And the furnace is still flawless! His honesty, integrity, and skill saved us. Johnny is the epitome of what you want in an HVAC professional. We owe him our gratitude for putting our furnace back together and truly saving us. Johnny is a true HVAC hero, and we highly recommend Core Heating & Air Conditioning! read more

John did us a solid a couple days ago when my attempt to install a nest thermostat didn't go all that well. We started to panic with the heating not working properly, extremely cold weather, and a newborn at home. Almost every other service we called were days if not weeks out. John came to our place that same day and looked over our whole system, fixed existing wiring issues, made sure everything was working properly and installed the nest properly all within an hour and even managed to teach me a few things and how to maintain things myself. He's an extremely nice guy to chat with and very reasonably priced. He will be the first person I contact now for any HVAC related issues. read more

John made my day again today. Last summer he came over to check off our A/C system with affordable and honest servive. This time he came on a Sunday afternoon to replace our gas cooktop. Besides his professional knowledge in heating and air-conditioning, John is also very good at computer and high tech gadgets, for our new cooktop is with wifi and bluetooth. We will definitely recommend John to our friends. Thank you, John, for your professional and first class service! read more

John is the very best! Last winter when our furnace broke, John assessed and fixed it in the same day. This summer when our AC unit needed a repair, again he fixed it the same day. Both units have worked perfectly ever since. John is super friendly, professional and obviously very knowledgeable. He is the only one we trust for HVAC maintenance and repairs. We would give more stars if we could! read more

Don't know why I waited so long to fix my summertime problem of an overheated upstairs office and bedrooms but visiting a neighborhood open house I noticed something I've not seen before, a whole house fan. Realtor told me how wonderfully they draw the cool air from outside and exhaust it out through the attic. I searched for these fans and realized this was not a DIY job for me so I started searching and calling around for a contractor. Made 3 calls and left messages. John from Core called me back the same day from a job site and said he could drop by at the end of his day and take a look at what I wanted to have done. He stopped by and spent about 1/2 hour checking out my attic and electrical system. We also talked about the fans I'd sourced. He gave me a price and suggested I purchase the fan myself and call him when it arrived to schedule an install date. With the heat of June upon me I ordered one from Home Depot with WiFi controls the same day. It arrived a week later and I called John to set up a date. We settled on a morning two days later. Wow! I was so pleased because we were expecting 90+ degree weather the coming weekend. John showed up on time at 8:30 and started working. He brought an assistant to help. This 24" fan has to be mounted on the 2nd floor ceiling in the hallway and set in the attic by removing a ceiling joist and building a frame for the fan to sit on. Then it requires wiring to a 120 Volt circuit and then to the WiFi hub box. The installation hit a couple of snags along the way but John easily worked through them and 3 hours from start to finish the fan was operating like a charm. I'm now able to turn it on to one of two speeds that automatically opens the shutter that covers the opening in the ceiling. John was truly a pleasure to have here getting this job done. He knows his stuff and pays great attention to detail. A bit of a perfectionist I think as he left the house as clean as it was when he came. The price was right. I am adding a couple pictures to this page of the job. I definitely recommend Core and will definitely call them again if I need anything done around the house that involves heating, A/C, electrical or mechanical. read more

Didn't have a clue of where to start, and stumbled upon Core Heating by happenstance. Called John this morning in a pinch to come and check our furnace which was in the basement that flooded overnight. He was very responsive and made time to come by same day to take a look and help us out. John was an all around great guy to deal with. Came in and did an amazing job of checking everything and explaining what was wrong, all while kneeling in a muddy basement. Even went as far as to recommend an app to better control our furnace, and checked all our filters. I could not be happier with the service, and would highly recommend anyone to contact Core Heating for any needs. Thanks John! read more

John came over and repaired our heater with ease. John was very friendly and took the time to show my son and I the steps he took to repair it. I highly recommend John and will be calling him from now on for any repairs. John felt like a friend rather than just another repair guy making a buck. read more

Freaking fantastic!!!! John is the nicest and most honest guy I have ever hired. He found the issue with my furnace and ordered the part I needed. We liked him so much, we referred him to a friend who was quoted $8-10k for a new furnace. They said hers was unfixable. John fixed it and her A/C for a few hundred buck and tuned them up. The others guys didn't even quote her for the A//C that was a different issue. All I can say is that it restores my faith in my fellow man when I meet people like John. There is so much dishonesty in home repair contractors, but John is one of the few with skills and morals. Please give him a call before trusting the big guys like Moore or Ongaro. You will thank me later. read more

John is amazing. Friendly, courteous, and straight up with you. Our old 1980s furnace was having some issues and stopped turning on. We called John and showed up the same day, extremely responsive. We were expecting someone to tell us we needed to replace the furnace, but after some quick diagnostics, John was able to troubleshoot the problem, fire the old bad boy up, and provide one of the most essential needs for habitability, and just like that our 1980s furnace was running smooth. John is a stand up guy, really enjoys what he does, and it shows. Stellar service, seems like he is getting busier and busier. Call him for sure. read more

As good as it gets. I called John around 3 pm today hoping to schedule a service call for our central AC thinking at least a week or so due to the high temps. He had an immediate opening due to a cancelation and was at our house less than 30 minutes later. Quickly and efficiently diagnosed our problem and found several other significant issues from previous work done. Two hours later as I sit here and write this review our AC system is running better than it has in the last three years and our house is cold! Honest, fair, and with a wealth of HVAC knowledge which is apparent after spending just a few moments with him. He also didn't mind our husky jumping all over him which was a huge plus. Thanks John! read more

You know great customer service when the owner goes out of their way to help you on a phone consultation & it's not even something they normally work on (which I didn't see beforehand on the business page.) John was so helpful and walked my husband step-by-step through the problem & how to best fix it. If the preliminary customer service is this good, I can trust that start to finish on a repair would be an excellent experience! read more

John diagnosed our fried circuit board lickity split and got our heater up and running in no time. Appreciated everything from quality to speed of service. read more

What a great guy. Totally helped out our AC was down and gave us excellent recommendations. We totally recommend this company!

Was lucky enough to get John recommend to me. My furnace stopped working and first I contacted a repair and sale company, which surprise surprise told me I need a new furnace, ac and all new ducting. Luckily I decided to get a second opinion. Turned out the furnace needed a little TLC, ducting need a little tape and the ac was fine. So instead of 20,000 it sit me a couple of hundred, and adding a phone number to my phone for the next time and for maintenance. Honest, efficient and charging a fair price for good work. read more

Need an HVAC expert? John is your guy! Friendly, professional, and a leader in his field who truly enjoys sharing his knowledge with others. (Check out his YouTube videos!) I'm proud to say I was among his first costumers, and I've used him for preventive maintenance on my home ever since. Now I have a business and he was my go-to to maintain my commercial HVAC too. He checked it out A to Z and not only revived it from neglect of previous tenant but found and corrected issues from the unit's original installation 10 years ago. John goes out of his way to make sure the job is done RIGHT and the customer is happy. read more

This past week - during our ridiculous heat wave - my AC died so I reached to John. He was extremely responsive and was able to make time within 24 hours to contacting him to check things out. Upon arrival John was extremely professional, very neat with his work and (what I really appreciated) walked me through the issue and the best way to address the issue. Within an hour things were fixed and John was very fair in pricing. I would recommend John to anyone needing help and will be certain to call him back for any type of maintenance, installation or repair in the future. read more

I needed a service on my furnace after buying a home 2 years ago and reached out to Core Heating. John returned my phone call within a couple of hours and scheduled a visit the next day. Working with John was a great experience. He has that friendly Petaluma energy that I love. Incredibly knowledgeable and honest. He not only replaced my filters, but adjusted the furnace to run more efficiently and installed a new thermostat so we can control heating from the upstairs. As a new home owner, I new nothing about regular furnace maintenance. John showed me how everything worked so that I could replace my filters in the future. Small considerations like that when you have a little one at home, very little time, and a new house to keep up, make a huge difference. Give him a call. You'll be glad you did. read more

Core Heating and Air Conditioning. John, 707 774-5003 We contacted Core heating and air-conditioning yesterday evening when our cooling stopped working. It was extremely hot and uncomfortable during this heat wave. Fortunately John was able to repair our air-conditioning issues today. He is friendly and knowledgeable, and he was quickly able to remedy the problems. We are very grateful for his service. We would use him again for heating and air-conditioning problems, and we would highly recommend him to others. read more

Expect just about anything when Core Heating arrives at your home. True, this man knows his trade (it took him less than 5 minutes to diagnosis the problem with my HVAC system, and fewer than 10 minutes to complete the actual repairs). Evidently, Core thinks highly of his acquired skills; I say "evidently" because my own acquired skills in diagnosing others has taught me to be cautious when face to face with behavjiors misaligned with conventional norms). Evidently, Core, the man, is (or emulates the actions of) a deeply preoccupied man. Money is not one of his issues, or so he says; however, Core's clarion call forimmediate, positive feedback appears to over-shadow, overwhelm and bring to mind the marketplace savvy contained in the words "caveat emptor". During the 90 minutes of heighten drama inside and outside of my home, Core managed to walk my dog, paint, snap tik-tok videos of himself, and speak at length about a trove of nameless others plotting against his business success. Perhaps this 4 year veteran of his own S corporation is simply hoping to expand his customer base. That said, my advice to others: "Caveat emptor." Expect just about anything when Core Heating arrives at your home, and you'll not be disappointed. read more

Whatever problems you have around your house, call John! He is not only a specialist and genius on AC/heating systems but also a true friend. Over the years, John came over to my house and maintained the water heater, replaced air filters, changed light bulbs (which were beyond my reach), fixed the garage door, checked the roof and gutters and even patched a tire! He would do things professionally but deep inside he just wants to help people! And he's got a talent to do so! Thank you, John! read more

John was amazing! Heat wave + broken AC = unhappy family. I called multiple places and they had a 2 week wait. John called back on his day off and came to the house and fixed it immediately. He and his daughter were friendly, personable, efficient, and explained everything very well. We now have a new Ac/Heating guy for life! Thanks again for being so awesome and now we can stay cool for the hot summer! read more

Excellent!! He actually brought my old dinosaur of a AC back to life. I was told it was beyond repair and looking at thousands for a new system. He took it apart and found a bunch of issues and fixed them all. I didn't think he could do it, but I was wrong:) he's amazing! read more

John came out the same day I messaged and was thoroughly delightful and efficient. Rather than sell me on a new furnace unit or parts I did not need, he cleaned my older unit and replaced two parts. John even patiently showed me how to clean the filter and do minimal maintenance in between yearly service checks. My pets loved him too! CORE is my new HVAC permanent contact read more

John was amazing. He came in and immediately diagnosed the problem and fixed it perfectly. Turns out that the builders of our home had not hooked up the wires correctly in our air conditioning unit so the dual zone system was not functioning properly. He resolved the issue quickly and even did some other things to improve our airflow. He was incredibly friendly and even played with our dog which made the dog very happy. He is super professional and I highly recommend him. He takes his job very seriously and really cares about making sure the issue is fixed. If you are looking for a great HVAC guy then look no further because you just found him!!!! read more
