My tenant thought maybe there was something wrong in the garage, where the furnace is in the house. She reported a burning smell and the co2 monitor alarm going off. I hadn't had the 25 year old furnace looked at in years and given the urgency, I called around to have someone come out same day. Carlos came out within 3 hours. Looked at the furnace, sent me pictures and called back. Explained that it was ok, he changed the filter, and gave me an estimate for replacing the furnace - but said it wasn't needed yet - and also mentioned that the exhaust pipe was at least 60 years old and no longer appropriate for modern furnaces. I appreciate Carlos giving me straight talk, not trying to convince me it needed immediate replacement and being able to come by same day. read more

I had an issue with my furnace and scheduled an appointment with Dennis and Pablo. I can't say enough good things about the experience! They were incredibly helpful, knowledgeable, and patient. After diagnosing the problem, they determined that the zoning board had blown and then walked me through the troubleshooting process step-by-step over the phone. What impressed me most was their expertise and willingness to help instead of immediately pushing for an expensive service call. They saved me a lot of money and a lot of stress. Dennis and Pablo are true professionals who clearly know their craft. If you're looking for honest, knowledgeable HVAC technicians, I highly recommend them. Thank you both for the outstanding service! read more

Excellent furnace service starting with Pablo personally answering my initial phone call (no AI or 3rd party out-of-state "customer service"!) who immediately dispatched the job to Carlos. Carlos was on-site within the agreed upon one hour time window and quickly diagnosed both the new failure and a long pre-existing but until then unknown problem. Kudos to him that at no time did he try to sell me on replacing the entire furnace (it's more than 20yrs old) but instead advocated just replacing the faulty parts. Fast work, knowledgeable service, definitely a company I would recommend to my friends. read more

Pablo and Carlos were very responsive and very reasonable. No upsell or hassle, just did the work that needed to be done and provided a lot of context and help explaining options. Will call them any time we have HVAC issues. read more

Pablo is responsive, knowledgeable, reliable and provided quality work to replace my very old furnace all within 3 days.

Quick to respond and high quality communication. Resolved with ease, no fluff. 10/10 will be calling again if we run into any issues.

We needed to replace an aging furnace in our SF apartment. I contacted a half dozen businesses and chose SF Heating and Cooling. Pablo was quick to answer my Qs and propose a model that worked well for our space and needs. Before going ahead, he inspected the space. The crew of three was able to come within a few days to take out the old unit and install the new. They were polite, efficient, and thorough. This firm is licensed and set up an inspection with the city, which we valued as customers. Their pricing is very competitive. I highly recommend using this company. read more

San Francisco Heating and Cooling - Newly installed furnace - Heating & Air Conditioning/HVAC Near Me - San Francisco, California

We just recently did the whole house wiring and main panel upgrade. Unfortunately while we doing the wiring and panel upgrade somehow after removing HVAC thermostat for couple of days, it's stop working even after I changed 3 different thermostat. So I turn to yelp and look for HVAC team which come across SF heating and had a pleasure speaking with Pablo, he was nice and assured me that his technician will come check to see what was wrong, he also mentioned probably it was fuse issue. After 15 minutes I got a call from Carlos and he asked me to bypass that thermostat and direct wire still didn't work, and I got another call from Denis who said he would come take a look and voila he found the issue right away and changed and install the new digital thermostat, boom it's working. Their attention and detail was A++, their response and service was A+++++. Now I know who to call when I need HVAC issue or time to upgrade new HVAC system. You will never go wrong with them. Thank you SF heating team. You guys are the best. read more

San Francisco Heating and Cooling - Nest gen-3 thermostat. - Heating & Air Conditioning/HVAC Near Me - San Francisco, California

I had an HVAC issue that involved water/plumbing issues. Carlos came out and was really helpful. Here's my view: Carlos gave me an education about my situation. The job was actually not one they could do right now but still he walked around it and looked it over and told me very clearly what my options were and advised me about how to proceed. The outcome is if I ever have any HVAC need there is absolutely no question I will call these guys. It can be hard to find people who seem honest, knowledgeable and like they give you the advise they'd give a friend. That's why I am giving such a good review. read more

Carlos was incredibly knowledgeable and consultative. Highly recommend! Rapid response time and easy scheduling.

Pablo is AMAZING! I called him to schedule a smart thermostat installation appointment. He asked me what's going on. I explained to him that I tried to install myself and since it was an old HVAC without the c wire, it needed a power extender kit. I went ahead and installed a PEK but in the process HVAC is not turning on and so I needed help. He asked me to come on video to diagnose and showed me the spot in the circuit to change the fuse and fix the problem. He could have easily taken the appointment and charged me but instead he chose to help me fix the issue over video with his extensive knowledge - such a nice gentleman! I learned a few things about how things work internally as well. I highly recommend Pablo for your HVAC installation, repair and smart home thermostat upgrade needs. read more

Carlos is a very nice person. He came and inspected my old furnace. I thought it needed to be replaced. He tested it and found out it was the switch problem. Quickly replaced. He shared some knowledge of the furnace with me. Great. I will stick to them going forward. read more

Highly recommend San Francisco Heating and Cooling for your HVAC repairs! They are responsive, have excellent communication, are very professional, and well-priced. I've called them twice now and Carlos helped us out both times. The first time was to fix our AC/heat when no air was coming out of the vents. Carlos was very professional and articulate in explaining his diagnosis, which was that the blower motor had failed and needed to be replaced. He provided us with a very reasonable quote, which we accepted. The replacement went smoothly and the issue has since been fixed. The second time, Carlos came out to help us figure out why the fan-only on our Nest was not working. He thoroughly accessed the situation and found that we had some unconventional wiring with our furnace - and that the fan only mode most likely never worked in the first place. He transparently shared that he was not comfortable with working on this unconventional wiring (due to the time and cost it would take), and recommended that we reach out to the furnace installers. I really appreciated his thorough explanation of the situation and his transparency. He also did not charge us for the visit which was very kind of him. read more

Our old forced air heater broke for the last time. We weren't sure what to do and these guys were great. They explained all of the options and did an incredibly thorough job on putting together the right heating/cooling system with zoning for upstairs and downstairs and they installed two new thermostats. They were communicative, knowledgeable, and they got the work done quickly and cleaned up when done. I highly recommend them! read more

I loathe to leave a good review bc a secret is better kept! Everything went seamlessly. When I called, I was put at ease right away - Carlos returned my call immediately and was able to come within 90 minutes! He is a true professional. Able to diagnose and solve my furnace issue (poor maintenance) within 30 minutes. I definitely will call on them and recommend them to any one in the future. read more

Carlos helped me out today and he was amazing. Patiently explained the issue with the HVAC system, told me why my HVAC board failed (because of one of the old nest units taking power from the board), and what the long term solution was here. I really appreciate his clear communication and professional service. Thank you! read more

Carlos installed our thermostat a couple of years ago and it started to act up (due to our inexperience with the buttons) recently. I texted Carlos, he responded immediately and we scheduled an appointment on the same day. He professionally assessed the issue and offered me a couple of options for consideration. The problem is now fixed and we are excited to have a working thermostat. I cannot recommend Carlos enough for his responsiveness, professionalism and excellent service. read more

Carlos was incredibly helpful. He walked me through furnace debugging steps over the phone. He was patient and explained everything clearly. Ultimately he was able to solve my issues over the phone at no cost. When it comes time to service our system, there's no question I'll be calling him back. read more

Pablo came came by and diagnosed our furnace and was able to replace it the next day. He was super professional and his price was very reasonable. Highly recommend to anyone in the Bay Area that needs some HVAC work. read more

Excellent experience with San Francisco Heating and Cooling. Our heater was quickly diagnosed, and the old mercury thermostat was replaced without any issues. Carlos, the technician, was fantastic - very knowledgeable, patient, and took the time to clearly explain everything. The service was professional and efficient from start to finish. I would definitely recommend them. read more

I'm happy to post this review for Carlos. Our heater thermostat failed in the middle of a cold spell; with temperatures as low as 58 degrees indoors. Carlos and I talked last Friday afternoon, and he gave me an appointment today, Monday, between "1pm and 3pm." He arrived @1:30pm, but after a half-hour advance voicemail heads-up. Fortunately Carlos confirmed our heater is fine, and replaced our thermostat with a new/updated model; taking the time to show me how to operate the controls. Plus, he replaced our old/original and very dirty heater air filter. I'm reliev to have heat again, and grateful for Carlos's prompt and professional help. read more

Sunday morning. Our furnace is dead. An atmospheric river is bearing down on San Francisco. After half a dozen calls, I got in touch with SF Heating and Cooling. Their man Dennis got back to me in 10 minutes after the initial call. In another 10 he was here. Turns out he lives in our neighborhood and had just picked up his morning coffee from McDonalds. Dennis diagnosed the problem immediately and we chatted out our neighborhood while the furnace cycled. The ignitor had gone bad as I suspected and Dennis diagnosed immediately. In another 10 minutes, we were up and running again and ready for the rain and chill. I'm very happy to rate SF Heating... with all 5 stars. read more

San Francisco Heating and Cooling - Heating & Air Conditioning/HVAC Near Me - San Francisco, California

I agree with the other 5-star reviews - this business gets my highest recommendation. In addition to being the most responsive to calls and setting appointments of any company I called, Carlos, their technician, has a straightforward and thorough context-based approach to diagnosis and recommended solutions that gives you confidence in what he's telling you. In my case, I was prepared to replace the thermopile in my ancient Gravity Feed furnace. When he arrived, he quickly diagnosed a microvolt wiring issue that was the root of the problem and made a simple change to lower the resistance in the wiring which worked without doing an expensive replacement. He also made great suggestions for future upgrades to wiring and safety equipment to monitor my antique furnace. :) The entire experience from first contact through to payment for services exceeded expectations. read more

An update to my review and upgrade in stars. As I mentioned Carlos was able to replace the thermostat the same day I called and did a good job. Pablo called me soon after and gave me a repeat customer discount that brought the repair cost more in line with his competitors. Thank you for being so proactive and caring to your customer. I have used this company in the past and agreed the repair was good and the price was reasonable. Based on current reviews I called them to replace a thermostat without getting quotes. I was very surprised/dismayed when told the cost of the service call. I asked if there was any discount I could apply, but the price was firm. The job was done so I will pay. I did call 2 companies after for quotes and the price I paid was almost double. My advice is slow down and get competitive quotes. read more

SF Heating & Cooling replaced our gas furnace. Pablo was awesome in addressing my requests and questions promptly both by phone and text. On the day of the furnace install, Wilbert and Liz worked diligently, performed testing and cleaned up. Afterwards, Pablo stopped by and personally checked the install work . Great team work and I highly recommend them . read more

Only if I could give these guys more than 5 stars!!! I came across SF Heating & Cooling by chance on Yelp after tiring of waiting on Fidelity home warranty and Home Depot quoting us $12K for replacement of new furnace. Carlos took his time and explained in details of types of furnaces, down to the sizes and costs of what different units would be beneficial. It was definitely an educational conversation. It made absolute sense after the phone call with Carlos that we booked them to replace our old unit that same day. He didn't even try to sell us the bigger and more expensive unit, except Carlos honestly advised us to go with what we really need, a less expensive BTU unit. Skip to the installation, the work was meticulously perfect. They even went above and beyond and did extra work, for no extra cost, to give us a better set up. I could not recommend enough Carlos and his team. They will be my go to guys for any recommendations and future needs. Don't hesitate when it comes to SF Heating & Cooling, you know you'll be in excellent hands! read more

If I could give more than 5 stars, I would! They responded to an emergency situation in less than an hour. My elderly father's furnace failed during a very cold night. Carlos, the technician, quickly diagnosed the problem, had the needed part in his service van and had the heat going again in minutes. He explained the new system to both my father and I and educated us on what to look for if there were any other problems. Can't recommend highly enough! read more

Carlos came by to diagnose within 2 hours of my calling, after talking through what might be going on via the phone.  He stayed and talked with us thoroughly about what might be going on and gave us different ideas of what to do, including likely costs.  For sure will follow up with them.  Thank you Carlos and SF Heating and Cooling! read more

Pablo is the best! Took my call and fixed my issue over the phone in 5 minutes. Can't say this expediency applies to everyone's particular repairs but can tell just by the way he helped me that whether your project is large or small you are in great hands! read more

This company absolutely deserves their 5 star rating. Our furnace broke down over the weekend and a technician showed within 2 hours of making the phone call. Pablo was clearly very competent and explained the issue in detail. He provided a couple of options but we decided to go with a full replacement of our unit. I really felt he did his best to help drive down the cost for us. The crew came two days later, on time, and finished ahead of schedule. The crew was efficient and respectful of our property which really appreciated. I would absolutely recommend them again, fantastic experience end to end! read more

I can't say enough good things about this company (specifically Carlos). I called today (a Saturday) hoping for a same day visit. The technician, Carlos, said his soonest availability was Monday- but then proceeded to spend 30 minutes on the phone with me helping me to diagnose the issue and giving me super helpful and thorough instructions on how to address it. He was so patient and went above and beyond to help me out. I'll definitely be using this company for any future servicing I need. read more

Highly recommend. Carlos was so helpful, professional and timely. And now I have heat!!

This company goes the extra mile. I called on Sunday and spoke with Pablo who was extremely helpful regarding my Mom's heater. He was patient and kind providing lots of good information. We set an appointment for Monday afternoon with Carlos. Later that Sunday Carlos called to inquire about the wall heater. We spoke extensively. He listened patiently and answered all my of questions. Long story short, the heater did not need replacing. Carlos followed up on Tuesday and provided more suggestions. Carlos and Pablo are "like your good neighbor" - a rare find in this busy world. read more

Highly recommend this company. Excellent work quality and price. Fast response to customer inquiries. Fair and reasonable price quote on new furnace. Installation was quick and high quality. read more

Very good service and price to install replacement furnace. Pulled permit and had all inspections.

Super responsive, communicative and efficient. The whole process was explained to me so I knew what to expect and I felt comfortable with my decision. read more

I Highly, Highly Recommend San Francisco Heating and Cooling!! I just need my thermostat replaced. After calling 2 other HVAC Service Companies, I landed on San Francisco Heating and Cooling, which BY FAR is the Most Helpful and Straight Forward and did not give me the run around, like the other 2 companies did. The Front Desk/Dispatcher took my info and within a few minutes, Carlos the Technician gave me a call back, and walked me thru a quick testing process, verifying my thermostat (and not the heater) was defective. He was able to help me schedule a Quick, Next Day Install! I really appreciate this company, and would definitely recommend it to everyone!! Nice, Helpful, Trustworthy, and Skillful! If you do call in, ask for Carlos to be your Tech. He's the BEST!!! We're now a Bunch of Happy Campers! read more

Carlos was incredibly honest, knowledgeable, and generous with his time. He helped me troubleshoot a wiring issue with our older Coleman gas furnace in our San Francisco home. Highly recommend! read more
