Professional. Kind. Safe. Smart. Efficient. Environmentally Responsible. Awesome to work with. Fantastic Communication. read more

Kevel Home Performance - Before and after! - Heating & Air Conditioning/HVAC Near Me - San Francisco, California

See all

We had an absolutely amazing experience with Kevel, from beginning to end. They gave us a home energy audit, and we moved forward with a project incorporating some modifications to our system. I give them my highest recommendation! 1) Every person we interfaced with was professional, and helpful, and just nice. 2) Project was timely, and everything worked out as expected and promised. The only minor drawback is that they are good at what they do, and popular, so there was a bit of time waiting to initially get our project in their queue. HVAC projects are also somewhat variable -- it's contract work and they are prone to weather changes, etc. so we understood, and the communication was excellent. read more

We recently moved to our new home and had to replace a super old antique furnace. We hired Kevel to completely redo all our ducting and install a new high efficiency furnace. Brian, Jeff, and Eric are a fantastic team! They installed the furnace, installed all the ducts, put in a brand new smart thermostat, sealed our registers, and adjusted all of the air flow for each room of our house. They also took care to seal some old asbestos tape that we had inside our very old floor registers, ensuring that our new system was safe to use. On top of that, they took care of all the work needed to get us a nice California Energy Upgrade rebate for our new system. They finished all of this in under one week! Not only does our house finally have heating again, but we feel a huge improvement in air quality in our home now! Thank you guys so much! read more

All the 5-star reviews are right. Jeff, Brian and John are amazing. They are incredibly knowledgeable, friendly, prompt, detail-oriented and professional. We had sky-high energy bills, and parts of the house were colder than others. From the very first phone call with Brian, I was impressed by Kevel. Brian asked very detailed questions, ranging from the temperature in different parts of the house to the humidity levels to the type of HVAC and kitchen ventilation systems we had. From that 45-minute call alone, he already gave preliminary, cost-free recommendations we could implement to help our situation. I scheduled the energy audit, and Brian and Jeff came over exactly on time and spent the day meticulously measuring and inspecting every aspect of our house. When they were finished, they gave me a quick overview of what they'd found, including some more pointers for ways I could drastically increase energy efficiency in our house at no cost (they also gave me a quick tutorial on my air filter/HVAC system, which I hadn't fully understood). A few days later, they emailed me a detailed report of their energy audit findings, and a list of proposed solutions. I had known from the get-go that I was going to hire Kevel to upgrade our home, so I was happy to see what they had pinpointed. Brian set up another call to go through their report, and we agreed to have them start work. The work on the house took a week. Jeff and John were both extremely smart, hard-working, and trustworthy. They even helped us fix our Nest thermostat (which hadn't been getting enough electricity from the existing wiring) and install the Nest smoke detectors we'd bought but hadn't gotten around to putting up. When they finished the project, they ran more tests, making sure to balance the air flow to parts of the house that needed it more. They did another energy audit test, too, and the house passed with flying colors. We noticed a difference in our comfort levels and energy bills immediately. Jeff followed up several times to make sure everything was working well. He also wrote up a detailed Improvement Summary. Kevel also took care of all the rebate paperwork that we were eligible for due to the energy upgrades. Jeff even checked up with the agency to make sure our rebate was being processed swiftly. I couldn't imagine a better experience than working with these guys. I will definitely be calling upon them again if we move, and I highly recommend them to anyone who is interested in making their home more energy efficient and eco-friendly. read more

This past fall we moved into a victorian flat on a busy street... We had no idea how loud it could be on a daily basis! We just had Indow Windows installed in our condo by Kevel Home Performance this week. We live on a very busy street in San Francisco and it has drastically reduced the road noise at least by 50%. We still hear some noise but it sounds much farther away than right outside our window. I finally get to sleep without being woken up in the middle of the night...! Thank you John & Brian for being so professional and responsive throughout the whole process. Indow Windows has improved our quality of life at home several fold. We would recommend Kevel Home Performance to anyone who has 'traffic noise' in San Francisco. The inserts are substantially cheaper than wood frame double-paned windows and related construction costs. read more

You are not going to find a better, more meticulous and professional team than Jeff and the gang at Kevel. We had bad energy leakage and balance issues in our house which led to huge energy bills in the winter. Right from the beginning, Jeff and Brian were communicative and thorough, first doing a full audit of the home to determine where the improvements could be made effectively, and then presenting a very well put together proposal with different price points for us to consider. The information given covers every aspect you'd want to know about, from estimated energy savings, to safety issues (in our case we had some asbestos removal), to recommended courses of action for maximum rebates from the government. They were also very open and responsive to the few significant concerns we had along the way. We were concerned about a few details in the asbestos removal portion of the project. Jeff did an excellent job listening to our concerns and acting to change the proposal in a way that really made us feel better about it. Pricing also I thought was very fair. And, the results in the end speak for themselves. Our energy bill plummeted compared to the same time period in previous years, and we can feel the difference in warmth in our 2 year old's room. That was keeping us up at night (not to mention the $300+ energy bills to compensate for it), and we are literally sleeping better at night thanks to these guys. I highly recommend Kevel Home Performance to handle your energy (and any other) home improvements. read more

These guys are the real deal. Being a business owner and an ex-tradesman myself I know how to spot a great crew. The Kevel crew are all highly knowledgeable, professional, thorough, and deliver as promised and on time. I could not believe that our 110 yr old house could be this comfortable. It feels like a new home that was built to the highest standards. I could go on and on with positives and after all is said and done this is the crew that I will recommend all my friends go to. read more

"Brian booked our appt. Jeff and John-they made sure as they worked their area was protected on our carpeting, explained everything as they progressed-great team work between Jeff & John. The company is an authorized installer of the Nest thermostat and they did a fantastic job! ..." So glad we spent the $ to use them! System works great! read more

Honest, hard working, flexible! The Kevel team came to our rescue when we needed to get our heating system replaced due to a medical issue. They understand allergies and health, and build that into the solution. Plus heating efficiencies. I asked a lot of them, and they delivered. I also checked three references before hiring them, and each one was outstanding. Hard to find contractors like this in SF! read more

Brian, Jeff and the crew are the best. Super customer service and results to match. Whole house assessment was recommended and completed on my home in San Jose. My home was so much more comfortable and my PG&E bills were reduced to match. These guys are detail oriented and their customer service skills are the best of any contractor that has worked on my home. I recently sold my home and one of the selling points was their energy efficient upgrade. Brian took the time and effort to find an efficient replacement furnace that was limited to a specific space in a hallway closet. They will walk you through the whole process from beginning to end including rebates with minimal effort on your part. Will use them again at my new house. This work was completed over 2 years ago. I have had that time to enjoy the comfort and low energy bills. House guests have remarked on how cool my house was during the summer. One contractor, who was doing 2 days of electrical work couldn't believe how cool my house was without using the air conditioner. He couldn't wait to get home and tell his wife. read more

I was such a skeptic but the guys at Kevel took extra time to walk me through the findings of our house evaluation and their recommendations. We had a super drafty house with colder rooms (one room being our nursery) and a relic of a furnace! Not to mention the on-going bickering between my husband and I over how hot or cold it was in the house! After Jeff finished the work, we immediately felt the difference in the draftiness of the house and when the heater runs, it warms all the rooms evenly which feels great. A few years ago we changed all the windows in our house thinking it would solve the problem - I totally wish we called these guys first! Definitely worth the investment and they were a joy to work with. The only time I've ever had work done to my house where the cost didn't change from the original quote and they finished on time! read more

Kevel performed an energy audit and then installed a new HVAC system at our home, including sealing the ducts, and making our old house much more comfortable with stable temperatures. Before their work, in the winter the inside temperatures would drop as soon as the heater turned off. Now we don't have the temperature swings. Also, as others have said their service is also top notch. They clearly explained everything along the way. We casually mentioned we were interested in registers and grilles that matched our late 1930's home and they sourced the perfect products. We've had a few questions after the installation and they were super attentive in their response. I cannot recommend Kevel more highly. read more

These guys recently did a home insulation for our 1940s home that had major issues of draft. They were GREAT to work with. They were very communicative, gave us lots of info and details about the project, and were extremely pleasant and professional. They are also up-to-date on technology which you don't find with many contractors. I would recommend them in heartbeat. And to top it all off, we are warm and cozy! read more

We heard about Kevel via Yelp and were impressed by the universally positive reviews. After an initial review of our drafty Victorian, they provided a menu of options to improve the comfort and air quality in the home. They were responsive, friendly, and extremely knowledgeable. They even discouraged us from more expensive work that would have provided limited benefit. In the end, we had them install Indow windows, seal a number of open air cavities, insulate below our flooring, and upgrade our furnace air filtration. The workmanship was first rate, and our home feels like a new, much more comfortable version of its prior self. We highly recommend this super high quality group. read more

Honest. Dependable. Reliable. Timely. Knowledgeable. Flexible. What more could you want in a contractor?

First rate operation. Kevel came to us by way of our asking for assistance in taking advantage of the Energy Upgrade California Program. We were working with Charles Windows and Doors of San Rafael, CA to consider replacing the windows and doors in our home and Kevel was mentioned as the Go-To company for starting the process to take advantage of the PG&E Energy Upgrade Calif. Program. From start to finish Kevel was most professional and competent in every aspect of our project and I can recommend them with the highest confidence in the quality of workmanship and excellence in planning. read more

In September, we moved into an apartment on a busy/loud street in San Francisco. While it's very convenient, the noise level through the old single-paned windows have caused the last few tenants to vacate the property after only a year. For awhile, we were sure we wouldn't last more then the minimum required by our lease either. Then, came Kevel Home Performance. The Indow Windows they installed for us dramatically reduced the noise level by at least 70%. While we can still hear some of the hum of the MUNI, it no longer keeps us up at night. Whereas we used to hear it every 5-7 minutes, now we only seldom notice the sound. While we are really happy with the final product, what makes me give Kevel Home the 5th star is the service. We spent most of our time talking with John, who was fantastic. He is quick, reliable, and communicated with us throughout the entire process. Since I work pretty long hours, he and the team were more then willing to work around my schedule and even come after dinner to do the final installation. This is such an amazing benefit in a world where you often have to take a half day off and wait for a vendor to show up sometime in a 4-5 hour window. I would definitely recommend them to others! read more

Best contractors I've ever worked with, hands-down. In addition to the energy audit, we had these guys install a whole-house fan for us, and then re-do our furnace and duct work as well as do shell-sealing and insulation. At every step of the way, they were clear about their schedule and kept all their appointments. They were always easy to reach by email and phone, and promptly answered questions and handled any changes we requested. They provided reasonable estimates and timelines and completed all their work on time. Over the course of our project, we worked with both Brian and Jeff as well as their associate Erik (their other partner had relocated to a different part of the country) -- they were all equally friendly, knowledgeable, and professional. Everything they do, they do well and thoroughly. Even when doing something small like replacing the weatherstripping on the front door, Brian took the time to scrape off a lot of old crud around the jamb so our door actually opens much more smoothly and quietly than it did before! Our home is now not only heated more efficiently, but also much more evenly, so our kids' room is now easy to keep at the same temperature as the rest of the house. Also, the whole-house fan is an absolute dream on the mid-peninsula, and is keeping our house much more comfortable in the evenings, now that the weather is heating up again. These guys were so great to work with that I've tried to think of other projects our house could use that they could handle. Unfortunately until we decide to replace our hot water heater, I think we've taken advantage of pretty much all their services. read more

UNBELIEVABLY GREAT quality work, customer service and communication. In these disappointing days and times of "I'll provide the least amount of service that I can to get paid and you have no choice but to like it" I found a gem in Kevel Home Performance. SF Department of the Environment introduced me an opportunity to increase the efficiency of the systems in my home, thus reducing my out -of-pocket expenses on electric and gas bills. After careful research of many companies that advertised they could complete the work at hand, I chose Kevel Home Performance. Suffice to say, Kevel Home Performance, made up of Brian, Jeff and John, blew me away with their unusually high level of knowledge, listening skills, honesty, work quality, customer service and an appreciation off my time and home. These guys are a "throw-back" to the days when companies actually gave a d#m about their customers and took pride in their work. Today, post Kevel Home Performance, I am enjoying, energy savings, but more importantly, I am MORE comfortable in my home than I have been in the last 9 years thanks to their suggestions. read more

TL;DR: These are some of the best in San Francisco. I even hit them up for other types of contractor recommendations. I can't believe the quality of work that they did for me, and am incredibly relieved to have chosen them to do the work. I got a 95% efficient furnace and heated a 1350 sqft 1916 condo at 70 deg F through December for ~$150 total with no added insulation. I am amazed! These guys are exceptional! I had been putting off installing forced air heating for a few years because every time the top 3 companies came to give quotes, they acted like it wasn't a big deal and gave me boilerplate responses. I had an uneasy feeling about their plans and didn't trust them. A coworker brought up Kevel and I decided to give them a try. The initial walkthrough took 3x longer than the other companies. This is because they are extremely thorough. They figured out different ways to accommodate our building and did some rough planning to make sure it would all work out. We discussed needs and locations. They didn't feel hurried at all and were very interested in the quality of their work. They're familiar with modern technology, so when there were questions about unexpected things in the building (100 year old building with strange history), they were quick to contact and text me pictures to get my opinion. They did a full Infrared leak detection for me as well and pointed out areas of the house that were leaking cold air which would end up costing me extra for no reason, and sent that along with detailed photos in a PDF for my future reference. I'd trust these guys to do anything for me. They are intelligent, polite, professional, and are always trying to do the right thing for everyone involved. I couldn't be a happier customer. I only wish they did more than HVAC stuff! read more

I had an acoustic indow window installed a few months ago and it has cut down the outside noise tremendously. I work night shift so now being able to sleep through the neighbor's gardener has been a blessing! I am so glad that I went with Kevel Home Performance. I originally talked to John, who was professional and quick to respond with an estimate. Then Brian came to do the installation. Brian was so friendly, knowledgeable, and professional, just an all around great person. He did a super job with the installation and even gave me home improvement tips for my home. read more

Jeff, Brian and the whole team consistently exceeded my expectations. They performed an energy audit, fixed the airleaks, and insulated my home. They were always clear and informative via Email and on the phone. My house is much more comfortable now, and I couldn't be happier with my experience! read more

We had a great experience working with Kevel on an energy audit and related upgrades this winter and spring. We found them through a friend and soon understood why they have such positive reviews. Everyone at the company is conscientious, professional, thorough, and extremely pleasant to work with. The team also knows its stuff. Our house feels more comfortable than it has since we moved in. Highly recommend working with Kevel - it's refreshing to encounter a team like this! read more

Brian, Jeff, and team were spectacular. Great communication throughout the process on top of excellent service and great work. A job VERY well done. Thanks! read more

From start to finish, my experience with Kevel Home Performance could not possibly have been better. All I knew was, my house was unbearably hot. I wasn't sure where to begin, so after reading their positive Yelp reviews, I sent an e-mail to Kevel asking about the price of a home energy audit. Brian responded immediately, and was extremely patient through my many questions over many e-mails. He was also completely understanding of my budgetary restrictions. Ultimately we decided a whole house fan could greatly increase my comfort level. On installation day, Brian and John showed up on time, were very professional, explained every step of the process, and left not a speck of dirt behind. When I got home hours after I had the fan installed, it was 85 in my house. I fired up my new AirScape, felt comfortable within minutes, and by bedtime the indoor temp had dropped to 72. Life-changer! I do plan on doing further home performance upgrades in the future, and will absolutely be using Kevel; they are a true pleasure to do business with. read more

We loved working with Kevel Home Performance to have Indow Windows installed in our home! Indow Windows saved us a TON of money, compared to the cost of ordering new double-paned windows. They help insulate the house from noise and the elements, and allow us to preserve the original vintage windows on our 1940s home. John was fantastic at providing customer service - very responsive and friendly. We plan to tell our neighbors about both Kevel and Indow Windows! read more

i love these men. from start to finish brian and john were friendly, reliable, professional and basically a god send in my mind. indow windows have transformed our house from feeling like we live in a screen porch (very drafty and being able to hear word for word each conversation and car go by on our busy street) to feeling like we live in a warm cozy library, seriously! the transformation has been a game changer and a very affordable way to get the benefits of double paned windows without the cost and construction. thank you kevel! read more

Kevel is outstanding! I recommend them 100%, and would hire them without question. They were exceedingly professional, affordable, and trustworthy. And VERY nice to boot. They went above and beyond, and the care in their work shows. We couldn't be happier with the experience. Thank you so much! read more

This review is long overdue - sorry guys! Jeff, Eric and Brian were just fabulous from beginning to end: explaining what they would do, how they would do it, the time involved, the process - everything. Their customer service doesn't get much better. These are guys who you want to stick around afterwards and have beers with, perhaps invite to your wedding, really. Did I mention the refund they helped me get? Much more than they initially thought - and in that way that describes how they work: under-promise and over-deliver, although it's not like what they promised fell short of any expectations either, but you get the point. So on to the work: First. I got a full education on home efficiency, no additional question was ever too much They had no problem with me walking around with them and watching what they were doing and asking questions - not out of suspicion but out of sheer curiosity.. It started with the home audit, finding leaks, assessing all HVAC stuff, and figuring out what work would be needed.The goal was to get from where I was (inefficient, lots of leaks and a heater that worked overtime to get my house warm) to near-optimal efficiency. First they did the audit (as many others have said, was really cool), they drew up a work proposal, outlined clearly what the estimated refund would be, and how long it would take to get everything done. And then after work was done, complete another audit to show the before and after effect. This increase in energy efficiency would be the grounds for a refund from PG&E. All the work was done on-time and the communication was great through-out. Jeff really went the extra mile to document what was done, still needed to be done, and when the work would be done. And when the refund would come! In addition to plugging leaks, replacing some duct/removing asbestos, and fine-tuning the airflow, we had insulation blown in to the exterior walls - not exactly a tidy process. BUT, and this was the amazing part, when I cam back later that day, there was not a trace of anything to show that a crew of guys had blown in messy insulation into the walls. Nothing! Gone are the days when work gets done but your house is left looking like a war zone.Everything was meticulous. And so in the end the refund ended up higher than initially anticipated. All told I got back about 50% of the upfront cost, plus a warmer house and lower hearing bills! Don't hesitate - hire these guys, you'll be happy you did! read more

We have a 150 year-old victorian condo and the windows are somewhat newer, but the house was not sealed completely. Brian and his team came in and did a leak test, went above and beyond to seal the building envelope as much as they can, and installed Indows. The energy performance enhanced drastically and the room that has the most leakage problem is now a comfortable room to sleep in. Brian and his team are professional, courteous, efficient, and are just a joy to work with. I am an architect and really value a good industry professional. I am looking forward to working with Brian and his team in future projects. read more

We needed to deal with energy issues at a 1906 cottage at our property in San Francisco from the East Coast. Jeff and Brian were professional, responsive, and were able to communicate well about the energy audit, recommendations, and work we scheduled via phone and email. The pricing for the work was very reasonable and the work well-done, and our tenants loved working with Jeff and Brian. They have also been very helpful in identifying and applying for the various energy rebates that substantially reduced the overall cost of the project. What one would want from craftsmen taking pride in their work. Highly recommended. read more
