Bro just call Marasigan if you need ANY HVAC work. Don't go anywhere else. In season 12, episode 13 of King of the Hill, Hank Hill talked about the importance of having a reliable professional on tap for projects. Well, Simon and Marasigan is my HVAC guy. Best service you'll get in Solano (and a little bit of Contra Costa) Simon owns the company, no middle man, and he has more than 17 years of experience working in HVAC. When I requested service for my AC, he would've literally been able to come check it out within half an hour! I wasn't able to do that cuz I was working, but he was able to work with my schedule. The flexibility is always great. When he came by, he was immediately able to diagnose the problem, told me exactly what I need, how much it was, and even taught me how to maintain it and diagnose issues on my own as well. No frills, no upselling, saved me money wherever he could, and most importantly, the job was future proofed as well. I got a great price for the work that needed to be done, and it was also done quickly. He even came early! What makes him stand out above the other HVAC services is that he even taught me how to increase the longevity of my unit. I knew that he really cared about the quality of his work, and making sure his clients are taken cared of. So yeah, just go to him! read more

Symond and his family crew did a great job replacing my Air Conditioner unit. Professional, personable, and very reliable. Symond obviously knows HVAC - very knowledgeable. They did a great job. Highly recommended! read more

I can't recommend this business enough, if you need any kind of hvac work just call Marasigan. Not only friendly, extremely honest and will tell you what can or can't be done and what's worth doing. Very rare breed of techs nowadays that are actual troubleshooters instead of parts replacers that just start throwing the parts bin at a problem. Will forever use these guys for any future HVAC needs. read more

My furnace was making an unfamiliar noise, and I was concerned and wanted someone to check it out. Marasigan Heating and Air had nothing but 5-star reviews, and they all emphasized how hard Symond, the owner, works to save his customers money. Symond opened up the panel and showed me how the furnace worked, gave me advice and recommendations for keeping the Heat and A/C operating smoothly, and checked everything thoroughly before determining that all was well. He did not try to sell me any unnecessary products or services, and he didn't even charge me any fixed rate, just said I could pay how much I wanted to since he didn't perform any specific service--I hope it was enough! The advice and peace of mind were worth a lot. I will definitely call Symond when I need any help with my unit. read more

I had such a great experience with Marasigan! Let me tell you, they are top notch. I had received 7 quotes from a couple companies in Fairfield that had decent ratings. They were all trying to sell me a product that I didn't want. Symond was the 8th I contacted. He didn't give me a sales pitch, he just spilled pure knowledge. I loved how he came in offering exactly what I asked for and even went out of his way to insulate one of the larger intake tubes. (6 out of the 7 other companies said they wouldn't do this). I couldn't have asked for a cleaner job. My gut told me to get an 8th estimate, and I am so glad I did. He emailed it same day as he said he would and I didn't blink twice as he was competitive. Communication was great from start to end. I will recommend them to all my friends and clients from here on out. Thank you Symond! read more

Marasigan Heating And Air - Clean job - Heating & Air Conditioning/HVAC Near Me

9/3/25 My experience with Marasigan Heating and Air Conditioning was fantastic. Symond first tried to troubleshoot with me over the phone in an effort to save me money. When an onsite visit was necessary, he set an appointment, he was punctual, and we worked together to come up with a plan to fix my AC problem. In the end, it promptly made the necessary repairs. If you need HVAC services and want the best in the business in my opinion, call Symond. read more

Marasigan Heating and Air did an awesome job. Called and spoke with Simon who was able to stop by literally within 25-30 minutes to take a look at what was going on with our furnace since it stopped working. I had an excellent experience from start to finish with great communication the whole time. Simon also walked me through everything and pointed out what could cause issues in the future without trying to upsell or overcomplicate things as well. I really appreciated how straightforward he was. He also worked efficiently, and left everything clean. You can tell he knew what he was doing and actually cared about doing the job right. From doing research online, the cost of the service was better than others I got quotes from too Highly recommend Marasigan Heating and Air if you want reliable, honest service! read more

Marasigan Heating and Air provides top notch services! Symond fixed my A/C unit when it went out this summer. To my surprise, my heating also went out this fall but Symond came to the rescue again! He is an expert at his craft, punctual and respectful of client's time and he goes the extra mile to help his clients -- whether it's explaining the problem and solution or running errands to pick up replacement parts. I highly recommend! read more

Symond came to the rescue! He was able to squeeze us in early to get our AC unit diagnosed and repaired for the hot summer days. He is very communicative and responsive through messaging chat. Arrived on time and was able to get done within an hour. He identified the faulty old compressor on our AC that needed to be replaced along with suggesting to add a hard start kit to help with prolonging life of the unit until we are ready to invest a new unit. Appreciate the reasonable transparency, pricing, estimate and speedy service. Highly recommend and will service again for future HVAC needs. read more

Symond was very helpful and knowledgeable. He walked my husband through some trouble shooting and knew exactly what the problem was. When he realized a part wouldn't come until next week, he sourced it from somewhere else, picked it up, and came the next day! He was on time and very friendly. We saved us from this dreaded Fairfield heat! Highly recommend! read more

I have been experiencing issues with my home heater for the past two weeks and scheduled an appointment with Symond, who has serviced my heater for the past few years. He was able to quickly identify and fix the issue within 30 minutes, as it turned out to be a simple repair. Although he did not request any payment, I insisted on giving him something for lunch. Symond is outstanding, and I would highly recommend him to anyone experiencing heater issues. Thank you again, Symond. read more

Our thermostat went out. I called Symond he first walked us through checking our thermostat. He didn't charge us. Unfortunately , it wasn't our only problem. He was able to be flexible with our schedule due to last minute changes. He was able to diagnose and fix our problem. He was patient and took the time to answer our questions. I really appreciate that we're supporting a small family business. Many thanks to Symond and his family for helping us out. I'd definitely recommend their service. read more

Marasigan H&A helped diagnose some of my heating problems and installed 2 new Honeywell Thermostats. A bonus was that Symond provided me with helpful education on doable indoor/outdoor maintenance. He was also very patient with my self-diagnosis and respectful of our home. I'd recommend MH&A to anyone who needs someone reliable; especially how quick they were to respond and were on time for our appointment . Appreciate that they also didn't sell me more than what I was asking for! read more

Had a great experience with Marasigan Heating and Air! My AC stopped working out of nowhere, and they were able to come out quickly. The tech, Symond, was super friendly and knew exactly what to do. He explained everything in a way that was easy to understand and got the repair done fast. No upselling or weird charges--just honest, solid work. The AC is running perfectly now. Would definitely call them again if I ever need help with heating or cooling. read more

Let's Go!!! A week ago, our A/C was working just fine until all of a sudden, it just stopped. I turned off the thermostat and then a few minutes later, the heater kicked on! And this was on the hottest day of the week!! I didn't know what to do so I simply ran over to our breaker box and cut the furnace from there and it stopped. I called the company that serviced our HVAC needs in the past and was told that due to high demand, they were only prioritizing appointments for customers who had a membership with them starting at $35/month! Seriously?! A membership for HVAC service just to get an appointment? No thanks. So now, I had to find another HVAC tech and luckily, I remembered seeing Marasigan Heating and Air's logo on the side of a truck and gave them a call. Symond responded to my message within 10 minutes of me leaving a voicemail and even offered to swing by my place the same day! Too bad I had to head out to work that day but we made an appointment for a day that worked best for both of us and he and his son came out to check out our system. Symond checked out the A/C unit outside, the furnace in the attic and our thermostats and determined that our thermostats needed replacing. He went out to pick up 2 new ones for us (we have a dual thermostat system) and within just a couple of hours, he got our system up and running again! Pricing was on point and very fair. I also appreciated Symond and his son's respect for the home by placing covers over their feet before entering and asking for permission before going into each room. Talk about care and respect for a customer's home! Marasigan Heating and Air are a SOLID 11 out of 10! Customer service is hard to find these days but these guys got it. Quick response time, thorough knowledge about HVAC systems, legitimate recommendations, honest pricing and great service. What more could you ask for? If you're reading this review, just go ahead and give them a call already. They are a solid 5/5 on yelp for a reason. You won't be disappointed! read more

We came back from a family funeral tired and hot Wednesday night only to discover our upper A/C thermostat wasn't working. Well, it was almost 90 when we got home and we were not happy campers to suddenly have to find a reputable A/C company to come out quickly and get this issue addressed and repaired. We looked at various A/C companies we had used before but were really NOT impressed with any of them. Anyway, we decided to try a smaller A/C company and went with Marasigan Heating and Air. Their YELP reviews looked good. Called Marasigan Heating and Air about 10 am Thursday morning and had to leave a VM for a call back. We quickly got an automated text stating he was driving and would call us back. Symond called back within 15 mins and asked about my problem. I told him my thermostat was having problems and it will not turn on in the upstairs zone. He asked me to text him a pic of the thermostat. He then called me and advised me that the Honeywell unit I had (which was 20 yrs old) was no longer being made. He advised me a new unit with larger numbers could be put in. I told him we might as well replace both thermostats at this time and he concurred. He asked me to text him our home address which I did. Symond texted me about an hour later and said he was on his way. He arrived in his nice clean truck and greeted me by name and with a smile. He put on his work shoe covers right away ,which I very much appreciated as I had just cleaned our tile floors downstairs. I showed him in and he quickly replaced both thermostats and vacuumed up the debris leftover from drilling into the Sheetrock to mount the new equipment. Symond then advised my how to self clean my outdoor blower and wash out the A/C drain pipe on the side of the house to maintain the system at its peak performance. All the time Symond was present he treated our home with respect and care as if it was his own home!! He asks permission from me before he entered any room as he had to enter our walk-in closet to get access to the A/C unit which was in the attic. Symond was a total opposite from our past A/C techs who never seemed to like having me look over their shoulders! Or who often would just walk inti our home in their dirty work boots. I recall more than once having to ask them to please put on shoe covers! All the while Symond was at our home he was friendly and open to our questions! Symond was a true professional and a joy to have in our home! I would not hesitate to recommend his A/C skills and services to any home owner! A BIG 5 STARS to what a A/C house call should be!! And the price was well below what other bigger A/C companies would have charge! For once an A/C professional who doesn't mind being watched and asked questions on what they're doing and being helpful in their maintenance suggestions NOT upselling some unnecessary part or service! We were totally left a satisfied and happy homeowner!! When can we say that these days!!! read more

I was having some issues with my air conditioning, so I gave them a call on a Monday to schedule a time they could come out for service. We scheduled for the very next day, and my window was between 10 and 12. Symond was right on time, he arrived at 10 on the dot! He was able to diagnose the problem quickly, obtain the parts he needed from his warehouse and get my issue resolved that day. I highly recommend this company for your heating and air needs! read more

Persisted in a difficult installation until it was completed to our satisfaction. Maintained professionalism throughout.

We had great service. He was the third person to check out our old unit and was the only one to figure it out in 2024 when it broke down in the middle of summer. We then upgraded our unit this year and completed the job in less than two days. We love our new AC! You'll need it in Vacaville. He was also very reasonable in pricing and was the best around. I hope you take a look at these guys and give them a shot! read more

HONEST & EXCELLENT SERVICE We had some issues with our HVAC system & we kept getting error messages on our panel (installed by a different company). Symond came out & discovered the issues. The temperature control was set up incorrectly & the system needed to be flushed. He explained everything he was doing & even showed my husband how to flush the system in the future. Symond was honest & didn't try to up-sale us on things we don't need. I would definitely call this company again for any issues & will recommend them to everyone. If I could give them more than 5 stars I definitely would! Symond was awesome! read more

I had my furnace and AC units replaced and I couldn't be happier with the outcome. Great crew, clean, easy to work with, reliable, trustworthy and exceptional service. I've worked with a few other HVAC companies and they give you the best value in Solano County. read more

Excellent service Very honest and didn't rip me off He did a job that other people would've charged 1000 bucks read more

I had called Cozy home service first for my AC problem, they wanted to replace the panel or the whole air conditioner. I didn't like that idea. I got Symond's number from my neighbor and he just rewired the panel and everything worked fine. Highly recommend him! read more

Called in the morning because my AC compressor wasn't working. Symond came out in the afternoon and was able to fix my AC unit on the spot. Thank you read more

We were in need of finding a new service provider to service our HVAC units as the company we previously used went out of business. I called around to discuss my unit that we have and Symond was very prompt in returning my call and confirmed he can work on our type of unit. Scheduling our home for service was swift after a holiday weekend! Symond and his son were prompt to the appointment time they were very detailed in the tune up, cleaned our vents as well and stayed around for a few to assure the unit rain well after the service! I will definitely be a long time customer of Symond's!! They may be small but Symond's attention to detail with his service is way better then these big service providers so definitely give him a call if you are looking for a service provider you can count on that will provide exemplary and detailed service!!! read more

Highly recommend this family owned and operated company for any HVAC needs. It is extremely rare nowadays to find such good customer service like my parents received from this company, I believe the owner who is Symon(spelling) came through to rescue my parents during this heat wave and was able to save them from burning up in a hot house. I can tell just based on our interactions, he is accommodating to his customers, fair pricing, gets the job done in a timely manner, honest and doesn't upsell unnecessary service, and is just extremely pleasant to talk to and work with in general. Will definitely be having all future HVAC work done with them! read more

Cannot say enough positive things about our service call. We had a sudden encounter with a weird smell coming from our heater vents and I wanted to get it checked out immediately. I looked up HVAC companies here on Yelp and this company stood out with all the positive 5-star reviews (with only one negative review?! and it was a communication issue at that). I called the number and it connected me to a voicemail that was a different number. I left a message, thinking maybe it might not reach them. But pretty soon, I got a text from Symond from the new number (he later said he forwards voice messages to his phone when he is out on jobs so he wouldn't miss messages) confirming they got my message and immediately gave me an availability. Symond advised me not to turn on our unit until he gets a look at it, just to be safe. When they came over, they were polite and respectful, even putting on shoe covers (which is a big thing for a no-shoe household). I admitted I didn't know where our unit was but Symond helped me sort it out easily and went up in the attic. He spent a long time there, all the while updating me below about what was happening. He came back with a video and explanation that everything was running well. He tested for carbon monoxide as well, to assure the safety of the air. Knowing I had very little knowledge about HVAC, some other company might have taken advantage and made up a problem they could "fix" and charge me a lot, but Symond was honest and assuring that our unit was working well. The video he took helped a lot to understand his explanation as to what could have caused the smell, and what problems to look out for in the future. He also went and checked our AC unit even though I didn't report any problem with it. Also of note, I asked him a ton of questions about maintenance to keep our HVAC systems running well, which he patiently answered and demonstrated. The whole encounter was professional, pleasant, very informative, and immensely helpful for homeowners like us! Needless to say, IF we ever encounter a possible issue, we know who to call. read more

Highly recommend! Our AC decided to go out last night and needed it fixed quick. I contacted Symond the next morning to see what he could do. He was quick to respond and made an appointment at noon. After diagnosing the issue, he clearly explained the problem. He was upfront with the costs of all the materials and labor needed to do the job. His work is excellent! He had my AC up and running in no time. Along with that, he saved me a ton of money! read more

They were easy to get an appt with. My furnace was leaking all over the place, like almost flooding everywhere. I got it checked first by a different company. The first company told me I need to change my whole AC system bc it's pretty old (abt 10-11 years) Called Symond for a second opinion before I give away my money. He checked it out and repaired it!! It's working great again!!! Saved me a lot of $$$$$$ for sure. They're honest and reliable and not just trying to sell new system. 100% recommend! read more

So we needed a A/C replacement. After dealing with these big companies that are full of it we found someone that is amazing. Great price, great service, and handled himself like a true professional. So happy with how you treated us. Like we were your family. Thank you for not trying to rob us blind. You are a rare breed my friend. Can't wait till this summer knowing the family will be cool in our home. Thanks again Simond. What a beautiful job!!! read more

Called for a service and they didn't even bother to return my call. If you've got an emergency or are in a bind, I wouldn't bother with this place. read more

My review was delayed a few months, but had to send this out to give Marasigan Heating and Air the recognition it deserves. During the summer, the fan in our AC system was not functioning. Sent out this issue via Yelp and we received a response from Symond. We got a timely appt with him......he was able to diagnose and fix the issue within an hour. With his diagnosis, Symond explained what needed to be done before making the needed repair.....to top it off, his price was extremely reasonable. For future HVAC issues, Symond and Marasigan Heating/Air is definitely who we'll reach out to. Thanks, Symond. read more

I beat the heat just in time for Memorial Day Weekend by choosing Marasigan Heating & Air do the job. My home did not have central AC and with the increasing heat waves year after year coupled with the devastating Nor-Cal fires, it was time to invest getting AC in my home. I'm so glad I chose Symond and his team to get the job done. They were professional, great with communication, and completed the install in one day. Everything from product information, installation process, and set-up was thoroughly explained as well as permitting and inspection process. Looking for a reputable AC contractor with reasonable pricing is difficult. During my extensive search, I had contacted many AC contractors and unfortunately discovered unreasonable high estimate pricing for the work and even far out installation dates as well as misguided information. It was truly by luck that I was referred to Symond by a friend. If you want the job done right, efficiently installed, and the best pricing, make sure you work with Symond and choose Marasigan Heating and Air. You won't be sorry!!! read more

Marasigan Heating And Air - Goodman AC Unit - Heating & Air Conditioning/HVAC Near Me

Siymond Marasigan removed our old furnace and air conditioner and reinstalled a completely new one. I wanted to share this review because he did a fantastic job. To begin with, he is very friendly and knowledgeable over the telephone. He centered in immediately on what we wanted and what we needed. He was able to access our property information online and recommend exactly what we needed for the size of our house. We discussed the different options, and I shared the budget that we had for this project. He not only met our budget, he offered us a price quote that was much lower than any of the other price quotes we had. This price quote included high quality products and was an out the door price that included everything from the cost of our new equipment to labor costs to taxes and everything else. The price was so excellent I was wondering if he would really stick to it. He asked me to take pictures of our existing unit and then set up a visit to personally examine everything and bring a work order. He is a man of his word. He stayed with his original quote, no extras, no hidden charges. We agreed and scheduled a date for the installation. He was right on time with his crew and the equipment. Everyone was very respectful of our home. They removed our old unit and disposed of it as we had agreed and then installed our new unit. They worked quietly, professionally, and very efficiently and finished everything in about six hours. I actually have a PhD in English, but I am at a loss of words to really express how much we appreciated his professionalism. He is the real deal! All I can say is check him out, and you may be pleasantly surprised just like I was. He is very friendly and really listens to what a customer needs and then let you know exactly what he will do. Everything was completed today just like he had promised, and all of his work comes with a 100% warranty. I highly recommend Marasigan HVAC! read more

Great quality work from this family owned business. 100% would recommend to anyone looking to upgrade their furnace or add air conditioning to their home. read more

I definitely recommend this company and will be referring them to my friends and family! read more
