Family had to recently endure a furnace install to finally replace the one that came with the house that my parents bought with hard earned money close to 50 years ago. Be prepared to sacrifice your major limbs to pay for this with this local company. ONLY VISA cards or PERSONAL CHECKS are accepted. Half of the payment is required to start the job. Remaining balance is paid after installation is completed. If you're priority is scheduling time for this and working with a tight budget it would be best to look for other heating companies that can FIT your requirements. You will get a summarized statement of work which is considered a contract. No itemizations of exact cost or hourly rate listed in the contract. Just an amount of what it will cost. You will get a spiel of what your first half of your money will be used for such as heating inspectors, debris removal, and permits, etc,. Also, the guarantee that work done would be up to regulation code. This is important for a homeowner as you can get majorly fined in the future if installation was not done properly. No price match will be given to a competing company. Basically, haggling will not make a difference. Make sure to monitor these expenses as well as actual tasks and actual crew that do the work. Removal, cleanup and installation went longer than the three or four days estimation of completion. Removal was done by another vendor specialized in hazardous materials. A previous customer had an emergency so this crew had to attend to it. Several days pass until the crew comes back to continue and finish the install. Luckily, during the week that this occured the weather was still warm and no space heaters were needed to keep the house warm. The crew of two to three people did a decent job, but one crew member needs to be more meticulous on the task at hand. You as the homeowner need to ask and comment on things getting completed. If it looks crooked or questionably placed speak up and either get it adjusted or keep an eye on it in case it affects other pipes close by. The crew are experienced as well as the contracted electrician that worked on the wiring and checking of the new thermostat. The electrician was thorough in testing functionality and overall completion. The cleanup after each end of the day by the crew was decent. Explanations and practical suggestions shared by them were appreciated. Overall, the guarantee of the installation was mentioned to be a year from installation. Heating is now dispersed efficiently throughout the house and quality of materials used is comparable to other vendors. The owner of the company does a walk through as the final inspection with you as well as review of the manuals that come with the furnace and thermostat. A recommendation of furnace filters is mentioned and the suggested type to use for your home environment. Unfortunately, a reusable filter of equal rating for normal use was thrown away without being notified if it was desired to be kept. These types of reusable furnace filters are NOT CHEAP. They come in different types and ratings so if you have one make sure it doesn't get tossed. The company owner is personable in nature and is helpful on recommendations regarding contractors used on installations. Only the constant promise of either stopping by to drop a receipt never occured. It took several phone calls to remind him, but still a no show and numerous responses of the days travails of why he could not send or drop a receipt by. The receipt was sent over through email finally, but it took numerous corrections to get the actual total amount listed. That is the only thing that is correct in the generic receipt received. Customer name was never corrected and no specific description on what the payment was for on the receipt as well as actual date it was paid. The date listed was when the receipt was sent. Plus I had to do a file conversion each time to check it as the receipt was in a macOS format. Do your homework and be knowledgeable on what type of furnace your paying for and its functional rating. In the end no heating inspectors came and the constant reminder of a receipt of payment took close to a week and half to finally receive by email. You do the math on this one. Makes you wonder what you really paid for was worth it with the amount of time and waiting endured as well as installation being up to city code specs. read more

Great service from Bill & Carl. They tuned up and cleaned my 25+ year-old furnace to keep it rollin' for another season or two. No pressure to sell me anything -- just great service, fast, friendly, knowledgeable, at a reasonable rate. Thanks!! read more

Excellent service. Super helpful and knowledgeable. Would highly recommend to anyone. First class.

Bill was quick with his response to my inquiry, gave me an honest quote, provided details of the repair that needed to be done, as well as different options. The follow up repair work was scheduled in timely fashion. I am skeptical when it comes to contractors, but Bill was someone I could trust. He didn't try to up sell repairs that weren't necessary nor tried to promote gadgets that I didn't need. read more

I called Bill to see if he could help me get my furnace turned on. It's one of the Williams brand wall units, and I've never turned one on before so really had no idea what to do. Bill asked me a couple questions about my furnace and knew exactly what I had to do. Instead of coming by and charging me a fee to get it done, Bill walked me through the steps so that I could do it myself and also advised that I search on YouTube for a video for extra confidence. I was amazed at the honesty and goodwill especially from someone I've never met before. When I do have a real problem in the future that I can't solve with some coaching over the phone, I will absolutely call Bill! read more

Prompt and friendly service! Bill is so kind and helpful with any of your questions. An expert in the field! Will definitely be calling them up any time I need HVAC work again. read more

Bill Kohler responded almost immediately for a furnace repair, did it quickly and even showed me what to do if it happens again. He's experienced, friendly, and cost was reasonable. Great service like it used to be. read more

Bill is really great. We will definitely be working with him again. Not only did our annual furnace maintenance go off without a hitch, but he also helped me brainstorm and solve other non-related house issues and plugged me in with recommended folks who could help in each area. Clearly he's at the top of his game and has been doing this a long time so has seen it all. He's also just down right kind. I had a false CO alarm go off in our house the other week and called Bill to figure out what to do about it. He pointed me in the right direction, and then called me back the next day just to check in and make sure everything was resolved. Two thumbs way up! read more

It's that time of year when everyone's heaters are on the fritz. Bill called me back in a timely manner, patiently listened to my woes and then gave me a referral to someone who works on the type of heater that I have. I'd trust the other reviews about Kohler's heater fixing capabilities; I can speak to Bill's responsiveness, professionalism and courteous nature. Sad to say, but rare these days! read more

Bill is an outstanding guy. Kind, courteous and knowledgeable. I would highly recommend trusting him with any Hvac issues. Simply the best!

Bill assisted me with a Williams Wall Furnace and over the phone walked me through resetting the unit and turning on the pilot light. Bill was able to get my unit up and running in less than a minute, and was kind enough to help at no charge. I would have paid him or had him come out; however, he was kind enough to help. Thank you Bill! read more

After our old and inefficient gas-powered hot air furnace broke down we wanted to remove it completely from the house and rely on other methods for heating our house. We called a lot of the top reviewed companies on yelp and Kohler was one of the only ones who not only answered our call but also gave us a budgetary quote over the phone - which ended up being the final price that they honored. Most places wanted to replace the furnace, not just removed it. We scheduled a time for them to come out and in only a few short hours everything was taken care of. They were very professional, fast and very clean. Overall we were very satisfied with the experience. 5 stars. read more

I originally thought the HVAC system at my house was very old and was worried there may be asbestos that could be airborne or anything that might break down, and there were many chilly mornings lately, so I had to find a heater specialist. I found Kohler Heating through Yelp and I'm so glad I did! I learned that they're a family business, which means they know all there is to know about heating and more! I worked with Bill, who was extremely professional from the start and explained everything to me thoroughly. On the first call, he gave me the basics over the phone and told me to keep an eye on the filter and to change if necessary. I really appreciate that he explained things to me, which most people would not do on the first call. He asked me to send detailed videos and photos of my heating system, which I did. To my surprise, Bill immediately called me back the next day to explain everything to me based on the photos. He assured me that the system looks pretty good to use and that he can try to come out to do an in-person assessment. He even gave me some advice about my water heater! Before we were scheduled to meet, I had more questions and decided that I could try to email him along with photos. I figured he might not reply since it's a bit of a bother without my business, but I wanted to try. Turns out, he called back the next morning and reassured me of my worries. He's quick to evaluate and reply, which I am thankful for! So the time comes for the scheduled appointment with Bill. He gave me a 3-hour timeframe, but arrived a little earlier than his approximate time, which I really appreciate! I don't like to wait all day for technicians and Mr. Fixits, but Bill was great about it and called me to see if it was okay to arrive a little early. When Bill was doing the assessment, he looked at the heating system and all the vents around my house. He did this all patiently and explained every bit of it to me. He was completely honest with me every step of the way and did not pressure me to make a sale. Even when my boyfriend had additional questions, he answered everything clearly and kindly. He gave me more knowledge and gave us some peace of mind. The ultimate thing I appreciate about Bill is that he took time to help me and didn't expect any business out of me. You can bet that in most cases, companies would not be willing to help or talk to you extensively unless there is money involved. I definitely recommend him for all heating needs. I just wish more people were like him out there, but I guess that's what makes him good to work with. I will for sure reach out to Bill for my heater needs in the future, no doubt about it! All in all, Bill is honest, professional, patient, and such a pleasure to talk to! Thanks a bunch, Bill! I really appreciate your time and assistance! read more

Honest, friendly, and fast service. Our furnace was constantly cycling on and off. Another company told me we needed a whole new system and quoted me thousands. Bill from Kohler came by and identified the problem was simply a bad limit switch. He had a new part for me the next day and everything is running great now - and I saved a boatload of money. I know who I'll be calling next time I have a problem! read more

Bill made it easy to get my wall furnace replaced. Friendly, knowledgeable, responsive, efficient, and reasonably priced. I was expecting to have this be a huge chore, but his team was in and out and did a fantastic job. Would definitely recommend! read more

I had Bill and his team out to install a new Ecobee4 smart thermostat in my home - and, unfortunately, the installation was nothing but simple, due to the fact that my thermostat wire only had two leads and had been spliced multiple times. I called an electrician out to fix that problem, but ran into a different problem after installation with the heater. Bill and his team were able to provide a quick fix, getting my heater back online and saving me tons of time and frustration. As far as I'm concerned, I'll be using them for all of my heating and cooling needs moving forward. So great to find a local company that does awesome work at the right price. read more

**HIGHLY RECOMMENDED** I had a great experience with Bill & Kohler Heating. Bill was easy to make an appointment with and came out on time. We had an unusual problem that was caused by a PG&E power surge. Bill told me what he thought it could be and what those issues would cost to fix. Happily, it turned out to be the lowest priced issue. He fixed it quickly and it works great. Bill was a very nice guy and gave me some tips on how to get more years of usage out of the heater. read more

Wow, these guys are fast, and good. We called on Saturday about a problem with our thermostat. They were there Monday morning. They fixed our problem in half the time and for half the price that I anticipated. You can't ask for any better service than that! Highly recommended. read more

I highly recommend this place. They set me up with a new furnace last week. Bill and his team are quick, very knowledgeable, fair and straight-forward, and Bill is an incredibly nice guy on top of that! Exceeded my expectations. read more

Bill is extremely knowledgeable, patient, and friendly. He was able to help me troubleshoot my issue over the phone! He was thoughtful enough to text me a day or so later to make sure everything was still working. Great guy! read more

Bill comes through and delivers! My heater was already 17 years old and stopped working when the weather was becoming very cold here in San Francisco. I went to Yelp and picked Bill out of the random based on number of stars and reviews. I am glad i found him. He answered my call and explained that he was booked for two weeks but would try to squeeze me in if possible. Believe it or not, my neighbor's 17-year old heater was also blown up and that neighbor already booked him earlier. Lucky for me, my heater was replaced within a week, and it was so perfect. I picked the dual-engine heater which was worth. He gave me the quote that covered materials, labor, etc. No gimmicks or gotchas. He was very communicative with me via text. Thank you Bill!!!!! read more

Bill was extremely responsive and I appreciate how comprehensive he was in explaining my options when my 23-year-old furnace pooped out. He and his crew were quite professional and efficient. I recommend Kohler Heating highly. read more

We had some concerns about the heating and ventilation set-up in our garage. Bill Kohler evaluated the situation and lent us his expertise. It was clear he knew the building codes inside and out. He informed us that everything was safe, explained why, and didn't even charge us for his visit! We will definitely be contacting Bill if we need work done in the future. read more

After a failed attempt by a handyman and several phone calls to other heating/HVAC businesses with no response back to get our furnace checked out after our heater stopped working in the beginning of January, I finally got in touch with Bill. He swung by the house on a Saturday afternoon, poked around, was able to diagnose the problem in a few minutes and and get our heater running again in just about 15 minutes. Bill was personable, easy to talk to, described what he was working on in a way that didn't go right over my head, and obviously very knowledgable about his work. 5 stars for Bill and 5 stars for a warm apartment! Thank you! read more

Bill cleaned my wall furnace quickly. He also was willing to arrange an appointment to fit in with my busy schedule..I will call him again.. read more

Bill was extremely friendly and knowledgeable when it came to replacing our heater. His team was also friendly, clean, and courteous during the few hours that they were here performing the work. They were very thorough in ensuring that all things worked before leaving and also made sure that no mess was left behind. What impressed me was their ability to work in very small and cramped spaces without leaving any sort of damage or mess in the surrounding walls. read more

What an awesome guy. He responded quickly to my call for a dehumidifier installation, indicated that he couldn't do it for a couple of weeks, but referred me to two others who he knew well, and wished me well. I love people who are upfront and helpful - I'm definitely calling him again when I need something done. read more

Bill did a terrific job on replacing our furnace. We got his name through Cole Valley Hardware and we were not disappointed. He gave us a great furnace at a reasonable price and agreed to work around our schedule. He was also very trustworthy when left alone at our house. He is also very thorough and great on any follow-up questions or concerns. The bottom line is that he wants to do a great job and it shows. This is a family business run the old-fashioned way, by a very nice guy who is focused on building and sustaining relationships with his customers. We're so glad we found him! read more

Incredibly understanding and will try to accomodate last minute emergency jobs. Had our furnaces in the upstairs and the downstairs both knock out in the coldest time of the year and he came down the next day to help us out. read more

I had a furnace issue after I got off a 12 hour flight. Jet lagged as hell, I called Bill at Kohler, and he patiently walked me through some DIY fixes, and low and behold one worked! I thought I was going to have to have an expensive repair, but Bill solved the problem with a 10 minute phone call and a few pics. Old school service, I'll be recommending him to everyone who asks. read more

Seriously Amazing! Bill Kohler was recommended by Cole Hardware and we are so thankful. It is great working with honest people. He has come out a handful of times in the last 3years for various issues. I called Bill at 8:15am about a burning smell and he ended up just coming out on a good faith visit, no payment required. He knows I have kids and wanted my home to be safe. Turns out we had a dead rat decomposing and he took care of it, he even disposed of it. Please note Bill is not an exterminator. He went above and beyond and we are so grateful. We highly recommend Kohler Heating for your HEATING/COOLING issues. read more

Having the heat go out during a cold snap is the worst! But Bill kindly fit in my emergency into his busy schedule and was great at getting my new furnace installed as quickly as possible, putting in extra hours in a way that was friendly and professional. The other worker (sorry I forgot his name) was even there working on his birthday! A+ and my thanks for doing a great job! read more

Wish the Yelp scale went to 11. Bill is amazing. I called to see if he could stop by to help with a thermostat installation. Rather than make an easy buck, he actually spent 10 minutes on the phone with me walking through the steps of what I should be doing. And then followed up the next day, completely unsolicited, to confirm that everything worked out OK. All without asking or expecting any $. Holy smokes!! What a great guy. I now wish I hadn't been able to fix it on my own as I want to shake this guy's hand! read more

The weather had turned cold and my furnace wouldn't start. Called them late on a Wednesday and Bill showed up first thing Thursday morning. He diagnosed the problem as just a wire that got disconnected, and fixed it. Here's the shocker: he offered to do it free of charge because it was so minor! He wasn't even going to charge a drive fee or anything. I almost dropped my teeth, and insisted that he take something. I literally had to force him to take my money. Then he took a quick look around and gave me some tips on how to reduce heating bills. Most extraordinary service call I've ever had. read more

WOW!!! My wife and I just moved into our new rental and as the weather turned cold it became time to turn on the heater...much to our dismay there was a hole in the back of the furnace and hot air was streaming into our garage. Bill Jr (owner) was out to our place ASAP and provided amazing service. Problem solved within 30 minutes for a superbly fair price! Not only that, but he spent a few minutes to make sure that there were no other leaks and even left me with some advice on how to keep my costs down through the winter. Truly one of the best, most professional service experiences I have had! read more

I just had the nicest talk w/ Bill Junior. I called him completely out of the blue to get some advise from a heating expert. I had no idea about Kohler at all, but I saw his name on Yelp, read some of the reviews....anyway, I needed advise about our heating system in San Rafael, and Bill couldn't have been kinder. He confirmed that what I had been told by a local Marin contractor was correct and accurate and gave me a lot of time on the phone. I can tell that Bill Kohler is a honest and trustworthy contractor. I would use him anytime. read more

OK, If you want a TOTALLY trust worthy guy for all your heating needs, look no further! Bill Kohler is the genuine deal! My son accidentally had pulled the handle off the stove, and it fell down the heater vent. I was afraid to turn the heat on, (A really cold SF morning), because of it. I called up Bill and he assured me that it would be fine. I said I was still a little nervous, and that I also needed him to check out why my heat wasn't getting all the way up to the top level of the house. He said he was very busy, but that he would try to fit me in this week.... We set the appointment up last friday, him saying he would be here Monday, between 10:00 and 2:00... Here's astonishing news...he showed up at exactly at 10:00am on the nose! (When ever do you hear that some business with a window of 10-2 comes first thing in the am?) That was really great. Anyway, he looked at my ducts, and said it would cost way too much for me for him to try to get the handle out of the system because of the sheetrock. He suggested that I should just get another handle. He even gave me the name of a place where I could get another. He then opened a shut valve that will now give me heat to the top level of the house!:) Bill was probably at my house for a 1/2 hour, he said, "Merry Christmas and Happy New Year! No Charge!" I tried to give him a tip and he wouldn't accept it. Bill is very professional and trust worthy. I'm happy to have met him and know that if I ever need my heater fixed, I'll be calling Bill! Thanks again! read more

Kohler heating is a fantastic company! Bill is one awesome guy! He goes above and beyond to help. A very trustworthy, fast and reliable company! I highly recomemned using Kohler Heating. read more

Bill solved my furnace problem within an hour of my call. Now that's service! He was friendly, helpful, efficient, and respectful of our time (which is my top criteria for good service!). The repair cost matched the quote exactly. Bill also took the time to help educate us about what to expect next with our old furnace. Just a great service experience overall. read more

Bill walked me through an issue over the phone and helped me fix a really small problem without having to call someone out. Small shop, has been in San Francisco for years, one of those companies that you always want to know about in a city. I'm glad they were recommended to me. read more
