Colin and his team were professional, prompt and did a great job at a very competitive price. One of those experiences that was so good - I'm telling friends about him. read more

Colin responded quickly when I was inquiring about my Nest thermostat installation. He was honest and did not try to oversell me with a new furnace. He looked at the furnace and said "it was clean." It's really awesome when you can find someone honest with any kind of repair whether it's home or car. Colin figured out a way to get this working because it wasn't as simple as I thought. He is thorough and patient. He is fair in pricing and Most importantly he was punctual. I would call him back in a heartbeat for any kind of HVAC or thermostat repair or Installation. It's great to know that I have found my HVAC person. Keep up the good work Colin! :-) read more

These guys did a fantastic job running heat into our bathroom and also installing a premium fan in the bathroom that vents outdoors. The work was done carefully, professionally, and it looks great. The guys even cleaned up extremely well after the work was complete. I highly recommend Air Tech. You'll love the work they do. read more

Collin came to my house in the middle of the holidays; late at night after my heat during a very cold week had stopped working from my HVAC. I had paid another, very reputable company to come and fix my HVAC. They ripped open the electrical, exposing wires, not able to figure out the issue and then pardoned themselves as they needed to run to her next appointment. They left my house after being there for less then hour, I was 8 months pregnant, had a 1 year old and my parents staying with us. The company called the next day and said the electrical issue was a problem with the unit and explained they could replace it for $3000. When I reached out to Tech Air/Collin he came over and anaylized the wires and tested electrical combinations for a few hours. He took his time to fix the problem. Then a Christmas miracle happened and my heat turned on. I literally cried happy tears! He was my night in shining armor and charged me a couple hundred dollars, which saved me thousands if I had gone with the other company's recommendation. I will forever be thankful to Collin at TechAir! read more

Huge shout out to Collin, who went above and beyond today! He actually picked up the phone when I called, and took the time to coach me thru some steps that might actually fix my AC without hiring him. Shortly after this did NOT work, he learned I lived in Clayton ... miles away from here service area (my mistake for not reading). At that point, he got off the phone, took the time to find a solution and called me back with the name of a colleague in my service area who would be coming the next morning. Talk about SERVICE!!! Thank you Collin, and thank you Tech Air for having such hi-quality people work for you!!!!!!! read more

The best!! After much research on split level a/c heat products, I purchased two Mitsubishi recessed ceiling cassette a/c & heat combined units from Tech Air. From initial visit for estimate, through installation & testing & final cleanup, every step handled to my complete satisfaction! Easy 5 Stars!! Colin is friendly, knows HVAC business and believes in happy customers! read more

Colin and team installed a new furnace with humidifier, including changing the location of the cold air intake and thermostat and replacing a duct. I'm so grateful I found him! Colin responded quickly, showed up when he said he would, completed the job on time and treated us and his employees with kindness and respect. He truly does care about his customers. His guys were great. I appreciated that they wanted to do, not only good work, but attractive work. They followed through with the finishing touches and clean up so that when they completed the job, I didn't have to do any clean up. Tech Air is the best! read more

I had an amazing experience working with Colin and his team. They helped us replace a brand new furnace and install an A/C unit for our home. What I appreciated most is the responsiveness and integrity from beginning to end. Even before we started, Colin gave me two different quotes and was honest about the cost difference based on options. Then, over the course of a few days, the entire team did a fantastic job with the entire install. I know it's always hard to find reliable folks out there -- especially when it comes to any work that needs to be done on your house. But I can attest to the quality you would be getting with Colin and the TechAir team. Highly recommend their services. read more

These Yelp reviews don't lie - Colin at Tech Air is the only one to call for HVAC work. A couple of months ago, our heater wasn't working and our house was freezing. Called another company first, who 1) couldn't figure out what was going on, and then 2) recommended we do full duct work to see if that would fix it. What?? As soon as Colin came in, he diagnosed it super quickly and had our heater back up and running. No duct work needed. And he was super transparent and fair about pricing. Finally, he followed up a couple of days later just to check that it was all still working fine. He's the best, and we're never calling anybody else for HVAC work. Thanks Colin! read more

Colin increased the value of our home by $100,000, let me explain how this genius of a professional and genuinely nice person made this happen. We moved into a new home in San Francisco's St. Francis Wood neighborhood and asked him for two new HVACs. All appliances were in a room in the basement. Colin looked around, climbed through a crawl space, and discovered that there was a hidden and empty room right next to it. He suggested demolishing the wall and building the new HVAC in the new room, which we then repurposed into the new Mechanical Room for HVAC, heaters, steam pump, etc. As a result, we were able to use the now-empty room to add a new bathroom and turn the adjacent storage room into a bedroom. That was the value add, and more than paid us back for what we paid for his work. Throughout the HVAC installations, Colin was incredibly attentive, a creative problem solver, and had a can-do-no-problem-i'm-happy-to-go-above-and-beyond attitude. He was the first contractor to work on the new home and set the bar so high that everybody else after him has paled in comparison. Colin and his team were a real dream for a homeowner for a heritage home that required extra special care. read more

I called randomly on a Saturday, and Colin picked up, walked me through exactly what to do, and wouldn't accept payment. Very helpful, responsive and knowledgeable. read more

I called Tech Air to come and see my furnace that wasn't working with our new NEST. They were prompt in returning my call and accommodated me on their schedule for the next day, which was pretty amazing. Colin came to the house and fixed the problem, and the heat in the house worked again. He was very professional and knowledgeable about what he was doing. I would use Tech Air Again and recommend them. read more

Really pleased with the responsiveness and work completed by Colin and his team. We had AC installed this past summer and would hire them again if needed for additional jobs. They were very nice and pleasant to work with. The follow up to make sure everything worked well was much appreciated. read more

I didn't end up using Tech Air, but I called Colin for a second opinion on an air conditioner repair that was proposed by another company. He patiently talked me through the process of that repair (without at all trying to sell me his services) and offered to come out to take a look. But, he suggested that I first contact the installer to see if the unit was still under warranty. Turns out, it was. Saved us a ton of money. Thank you, Colin! I will certainly reach out for any repairs once the warranty has expired. read more

Left a message Sunday night and he called me back first thing on Monday morning. He was able to come out on Monday morning. He is methodical in his diagnostic skills and really quickly determined the problem with my AC and was able to fix it. In and out within a half hour and my AC is back to normal. Very professional. And, because I was curious about the inner workings of an AC, let me look over his shoulder and he explained it all to me. read more

Furnace stopped working. Colin came over the same afternoon that I called. Diagnosed the problem as a faulty circuit board due to moisture. Showed me the board. Was able to get a new one locally and installed it the next day. Can't ask for more than that. read more

5 STARS! We received several quotes for a Trane AC system with ducts before finding Colin and Tech Air in Mill Valley. Colin and his team are genuine and fair, and take immense pride in their work. They worked efficiently and set clear expectations, informing and including us in any major decisions to be made. For the one modification required, they only charged us the cost of the additional part, but not anything more and even patched some unrelated dry wall for free. When the project was completed, they returned to ensure the system was operating and our inspection was approved. We highly recommend them for their exceptional service, professionalism, and friendly local feel. read more

Tech Air - Heating & Air Conditioning/HVAC Near Me - Corte Madera, California

Collin of Tech Air got back to me before anyone else I called and I left messages for about ten different places. I wasn't messing around trying to get my A/C fixed in the Summer! He arrived when he said he would. Promptly accessed our A/C, got the needed part and returned that afternoon to fix it. Now it works great. I will call him again for any problems that arise. read more

Can't say enough great things about Collin and Tech Air. Our 20+ year old AC went out in the middle of a heat wave. Found Collin/Tech Air and read 5 star review after 5 star review. He actually answered the phone himself and booked an appointment to come out the following afternoon. Got a call the very next day from Collin telling me he was in the area and could come by 3 hours early - he had the problem diagnosed in literally 5 minutes- had a replacement part in his car - fixed my AC and it's like the Arctic in here. The cost was more than reasonable. I can't recommend Collin enough. read more

Collin is extremely professional, polite, on time, knowledgeable, and easy to communicate with. I was beyond pleased by his service and will most definitely be using Tech Air again if needed! read more

We came back today after two weeks away for the holidays- to a cold, cold house. My furnace wasn't working. I found Colin through Yelp, and he did not disappoint. He answered my call on Saturday, and was able to come to my house the same day which I greatly appreciated. He did warn me that he might not be able to fix it the same day if parts were needed- which I liked as it didn't give me any hope of a same day fix. However, due to the nature of the issue, he was able to diagnose and fix the issue the same day, same visit. I'm so grateful and happy that my heat is working- and that I found someone I would highly recommend and use again to service or install my HVAC. Thanks again, Colin! read more

I discovered that my heater wasn't working right as weather was starting to cool down. I reached out to Tech Air and got a quick estimate, and was told that someone could come out the next morning. Colin showed up on time, was friendly and professional, and got my heater working in no time. The price charged matched the estimate. I'll be using him exclusively going forward for any heating issues I have. read more

Colin and Reggie were fantastic - super responsive, responsible and in one week time we have a brand new A/C unit, new duct tape work and a new furnace. Colin did everything as promised and the cost was very reasonable compared to other estimates we received. Definitely would recommend him and his company! read more

We needed our furnace replaced and Colin was the best price, very conscientious, showed up when he said he would, was very professional and super nice. He got the SF building permit for us, did a really nice job on the installation and insulating all the ducts, cleaned up really well, and came back another day to wait for the inspector to show up and sign off on everything (which was passed easily). Highly recommend Colin of you need any HVAC work done. read more

I highly recommend Colin with Tech Air! He was a great problem solver, repairing a heating duct in a very funky location, without having to replace the whole thing. He saved me a ton of money and got the job done very quickly. He also installed my new Nest thermostat! He was professional, courteous and an all around nice guy. You would be lucky to have a guy like Colin to help you out of you every need repairs to your HVAC system. read more

Called Collin at 930am, heater fixed by 3pm. What is not to like? Collin did not try to sell me a new furnace...he just quickly diagnosed the problem and got my old furnace working. read more

As others have said, Colin is kind, professional, prompt, and fair. I would definitely recommend reaching out to him for your HVAC needs.

I found myself just smiling and nodding my head reading through all the reviews just now, naturally all 5 stars. I was desperate for heat as my 83 yr old dad stays with me most of the time and for the first time I stayed cold through the entire night in bed more than once. Colin was the ONLY service/repair tech who didn't hesitate to make time in his schedule to come help fix my furnace. Out of like seven total who generously offered to do so in a week or two or just not at all. They're ALL busy right now. The difference is that Colin is the obvious exception because that's the kind of guy he is. He's a big exception. He didn't have the time either so he literally created more by working into the night to accommodate everyone possible, me included. I don't know about you, but for me, that's all superhero, knight in shining armor, holy savior, rockstar stuff, because-- and here's an extinct concept-- he is genuinely dedicated and goes out of his way to deliver that dedication for our benefit. Integrity these days is a rare find. The tremendous and unexpected bonus is that he's super efficient, professional, helpful, FAST, reliable and punctual, God forbid even reasonable, AND gets it done proper. And at the risk of sounding mushy, he's all that and a super pleasant guy, for God's sake. Refreshing? Exceedingly so. He showed up at 8am (after first offering to come the night before when I called him), diagnosed it so quickly (I already had two other people misdiagnose the problem as originating from an entirely different part), then on top of juggling all his other jobs the rest of the day solid, he magically and gallantly arrived that evening with new furnace circuit board in hand. Ten minutes later max, BAM. Heat, glorious heat. I feel-- no, I KNOW I got real lucky stumbling onto Colin/TechAir. I'd never even consider anyone else-- ever. And I won't let any of my peeps call upon those "other" guys either, not if I have anything to say about it. There would be no point because there no longer is any other option. Thank you, Colin. Like I said and I'll say it again, you "singlehandedly improved my quality of life enormously today". read more

Colin came promptly and determined we could use a new furnace. Ours was 50 years old and stopped working. He and crew came in and installed a new furnace in a few hours. Cleaned up and hauled away the old furnace. We wouldn't hesitate to hire him again. read more

Colin came to fix my thermostat within 30 minutes of me calling him. He was friendly and got the job done in less than 30 mins after arriving. He has some thermostat options on hand and saved the day from having my toddler sleep in cold conditions. I am so grateful for his help and would recommend him to anyone. Thank you! read more

You're searching is over! I'm a former contractor and pretty picky, I got multiple bids for a complicated installation of a heat pump (complicated hi tech heating and cooling system). Installing a heat pump is more involved than installing a forced air heater or installing an air conditioner. Colin at Tech Air gave me the best price and did everything he said he was going to do, on time and with excellent service. He takes customer service seriously, not something you always get with a larger company. You won't be disappointed with Tech Air. read more

Colin installed an air conditioner for me. I highly recommend him. The job was well done, he's courteous and has great customer service. I've called him for help two separate times for a thermostat issue and a furnace issue, separate from his job and he's come out to fix and help at no charge read more

I'm really happy to add to the chorus of Collin cheerleaders. This kind of customer service is rare indeed these days. Collin was the only one of several folks we called to return our call on a weekend. Then he came over, still on a weekend, pretty much straight from the airport to diagnose our broken furnace. As promised, he kept us up to date early the next morning about getting parts, and then drove all the way to South San Francisco during Thanksgiving week to pick them up! Our furnace is back up and working and he even called to follow up and make sure it was the next day. Wow. Don't let his chill manner deceive you. He's dedicated, knows his stuff, goes over and beyond the call of duty and really cares. read more

A great team. Colin, Hannibal and Israel are why I love working with small teams rather than large companies. Prompt, flexible, considerate and very skilled, they were happy to install a new LG mini split system that my wife and I chose even though it required extra time to study and learn and was fiddlier to install. They communicated very well throughout and always turned up when they said they would, as well as honoring the original quote even though it took longer than we all expected to install. Being a retrofit in a very old house they had had to be both very flexible and creative with how to run the piping and cabling and they excelled at both. In addition to all this they are all genuinely nice characters, interesting people with fun stories to tell while you are waiting for the electrician to finish his work. read more

Colin was professional, friendly, reliable and he fixed our ongoing issue with our furnace in the timeframe provided and price quoted. First he suggested that we replace our air filter to avoid having to pay him for a simple fix which was thoughtful. The job ended up requiring two trips due to special parts on order but it didn't take long to fix and he communicated timing throughout. We are thankful it is finally fixed. read more

Simply put, Colin is the man. We were having issues with our heat, and he responded to my first outreach immediately. I made an appt for the next day or two, and he showed up on time. He diagnosed the problem in no time flat (we were idiots and hadn't changed the filter in forever). I took the opportunity to ask him about adding a zone to our house - it had been only one zone controlled by a thermostat downstairs. Since heat rises, the upstairs would get really hot, while the downstairs stayed cool, as the heat would run through all the vents throughout the house and the upstairs would get a double dose. I had asked another HVAC company if it were possible to add a zone 2 years ago when we moved in, and they quoted me more than $10,000. Colin climbed into the attic, took a look around, and said he could do it for 1/5th of the price, which included another Nest control (and he didn't charge for the first visit, calling it an estimate visit). He and a colleague showed up on the appointed day, on time, and completed the job in the time he said it would take. Colin was clearly sick as a dog, but wanted to live up to his word and get it done. The whole system works perfectly and in the end, we're going to save money because we're not wasting a bunch of energy. Could not be happier with Colin and Tech Air. read more

Our Carrier 58MTB heater made a loud buzzing noise when turned on. We checked out Yelp, saw these 5 star reviews for Tech Air and called Colin who arrived the next morning. After spending about an hour diagnosing and attempting to rectify the problem he explained that we needed, a draft inducer motor assembly. He called the supplier on the spot and presented the cost to us for material and labor. Two days later Colin arrived on time-thankfully again, with a face mask, which he wore the entire time as a preventative measure to guard against Covid-19. He completed the installation, explained what he had done, let the system run and left the area clean and ship shape. We are glad we found our professional"go-to"guy for future repairs. read more

I called Tech Air to fix my furnace and the technician was very professional. He did and amazing job and I am so happy with the results, my furnace has never work better! read more

Colin responded to my call and texted within an hour. He was onsite same day and gave me all the advice I needed. He inspected the furnace and recommended some simple fixes that would improve its performance at low cost. He warned me what to look out for as I did this work and gave me very candid advice on when to replace my equipment. Looking forward to working with him again soon, even if that means my furnace has finally kicked the bucket. read more

I felt the cold air through the vent and after seeing the 3 light flashes, knew I needed professional help and fast. Colin was able to get out the same day. He was upfront about his pricing on the phone. He was very knowledgeable and walked me through each step he took to diagnose the issue. I would recommend Colin and his services to anyone who wants a local HVAC repair. read more
