Keith is the greatest!! I called for an estimate on a Friday, and Dan came out that same day! I had my new air conditioning unit up and running the very next day! On a Saturday! These guys work!! Just in time for the heat wave!! To add even more excellent customer service to my air conditioning experience, my thermostat was acting up so I called Keith at 7 am, thinking I could just leave a message and get someone out next week. Keith called me back within minutes and was at my house within the hour! Replaced the faulty pump and had my air running before 9am on a Sunday!! Love these guys! Thank you to Keith and his crew!! read more

This company and their technician, Jared, saved my family almost $4,000 by being honest brokers and fixing our unit quickly and with integrity. RR AC repair in Simi massively overcharged my family and were prepared to charge significantly more for problems that did not exist as Jared proved to me. Anyone looking for an HVAC fix and a wholesome company that doesn't prey on normal folks who don't know how these giant machines work: use Keith's and ask for Jared. Absolutely great experience. I'm very thankful these guys came out and did what they did. read more

I have used Keith in the past to fix HVAC issues at my office building but, this time I had an issue at home. In the midst of our heat wave, my central air conditioner at home quit working. The family was sweltering. I called Keith in the morning and he was there the same day. He diagnosed the problem and had the replacement part on his truck and the problem was fixed in no time at all. He charged a very reasonable price and we were back to a cool, calm, air-conditioned house. Many thanks to Keith and his responsiveness. read more

We have two air conditioning units and suddenly one started struggling. Of course, it was the hottest day we had had in weeks. We shut it down and looked for recommendations on the Next Door app. Keith was highly rated and local so I put in a call the next morning, figuring we'd have to sweat it out for a couple of days. Surprise! Keith called back and said he could slot us in that afternoon. He called as soon as he got off his previous job and called again when he was out front so we could mask up and social distance. He started testing connections and diagnosed the problem quickly. Had the part in the van and gave us an estimate that was at least a third lower than we expected. The unit was back online and humming in less than an hour. We would not hesitate to call him again. read more

FANTASTIC experience from beginning to end! Jared took time on the phone to explain the process and was at our home within a day to provide an estimate. We needed a new HVAC system as our was 30+ years old. The install included all new duct work and bar grates. Dan and Tim did an outstanding job installing the new units inside and out. We had been looking for a great independent HVAC provider who would provide great units for a competitive price - we found it! We also wanted our furnace installed in the attic and that's what we got. All to code and done right. The furnace and condenser are by Ruud (manufactured by Rheem) and are solid units. Cannot say enough positive things about Keith Heating and Air Conditioning. Jared, Dan & Tim: great job, guys! read more

He's so good that I never needed to call him again. Dear Keith fixed a switch and hardly charged me anything for his work. He said, "that's ok. I'll get you next time" He's a really sweet guy with knowledge and heart. He won't con you into replacing your whole air conditioning system. He will fix it and charge you very little. Call this guy if you really need help and want to keep your money within our neighborhood to benefit our economy. Everyone else wanted to replace my entire system. That costs bucks! read more

I cannot say enough on this post to explain how happy I am. I was looking for someone to fix my heater and I'm so glad i found this number. Fast response, excellent service, and great price. Kieth is amazing and i will be using him for all my future heating and air needs... read more

I spoke with Keith in the middle of the day Saturday expecting to make an appointment early in the week, but Keith was AWESOME!! He came out on a Sunday morning and saved my family and me from another unbearable night in the heat. I highly recommend him as he is polite, very professional, and didn't mind my two little ones asking him every couple of minutes on what he was doing. The air conditioning unit was fixed and is working great. I'm glad to have met him as I will be referring anyone who asks for HVAC related issues to him. Thanks again Keith! -Casey read more

I have several rental condos. Keith has done a complete new install of a HVAC system on the roof. He worked with the HOA, (a few AC guys wouldn't do the work because of the HOA). He did the work quickly, cleanly, and had a fair price. Tonight I called about another condo that I have, and within an hour he fixed the problem, again at a more than fair price. Keith is the best HVAC specialist that I have used, and I've had several. He's my go-to guy for this this stuff now. Thanks read more

Keith is the man! Our AC stopped working and it was 95 degrees out. In the past we have had trouble getting any out to help on a hot day in our area, but Keith was able to make it out within an hour of speaking to him around 5pm!! He was able to quickly diagnose the problem, replace the part, and get our AC up and running for a reasonable price! read more

Loved the fact he came to check my system while he had a back surgery, and did try to come up with a problem to charge me for it. Keith was kind, honest . He will be the first to call for all my AC works read more

It is a great comfort to work with people who you get a feeling of trust and honesty from. Dave came over today to fix my air conditioning, and when just checking the system from one side of the house to the other somehow managed to fix the problem, all it cost me was the service visit cost. I had already tried this myself, but when an expert is testing everything they are more likely to find what I had missed. I know that I may one day soon need a greater repair or even a replacement, but now I have time to prepare for that possibility. 2 years ago I had a similar problem with my heater, and Keith bought me the time to plan for the cost by finding a way to keep things running a bit longer. I'm very glad to see he has man like Dave working with him who have the same solid ethic. I saved a lot on that heater, and I believe that if the A/C does need replacing it will be quick, professional, and a great price. I got other bids on that heater years ago and saved a bundle with Keith. He has earned my trust and that goes a long way. There are plenty of scoundrels out there, don't let them fool you, these are often expensive fixes and you need to have someone you can believe in. Dave just convinced me that this business still deserves that trust! read more

Our air conditioner's condensate pump broke resulting in a condensation leak. The owner Keith called back promptly and was able to install a new pump the same day. Keith and his crew are honest, knowledgeable, reliable, prompt and all around great people. I highly recommend Keith AC for any service and installation needs. read more

Keith was the best! He returned my call quickly, was very friendly (though considerate of current societal norms), and his pricing was awesome! He was done much quicker than I thought, and helped me and my son out immensely. I will use him again with no hesitation at all! Thanks, Keith! read more

Keith's guys fixed the AC for much less than the competition quoted. They found a small problem the other guys did not even address. I feel I got a great deal, an honest evaluation and job well done. They were clean and careful. They will be my guys to call from now on. I have recommended them to others and have not heard anything negative about them. read more

As was mentioned earlier. I have found an honest man. Keith and Jessie came out for repairs very quickly: Same day within 4 hours. They quickly determined what the problem was and advised me of steps needing to be taken, as well as costs. A new part was needed, and that part was in Ventura. Keith arranged for the part, and was back the next day. Keith came with John, as an assistant, and they both had my furnace up and heating within 2 hours! HooRay! Wonderful heat! Keith and John remained to verify all was well while the furnace did it's job: Perfectly! I whole heartedly recommend Keith heating, and I now have a technician who is responsive to my needs. If you need HVAC service, call these guys FIRST. read more

I called Keith during one of the hottest days this summer to set up a future appointment to have him come and see if my old air conditioner was able to be prepared. I left a message for Keith who promptly called me back and told me he would be over that very afternoon. He arrived when he said he would and for a VERY reasonable price, he had my air conditioner up and running in less than an hour. Loved his professional, honesty and energy. I've already recommended him to my neighbor who also says he did a great job on her unit. Thanks Keith! read more

Keith came out within one day of being called and gave us an honest evaluation of our older HVAC system. We knew it was a big investment and wanted it done right, and he was open to several different options of how to get it done. Once we committed to going with Keith, the work day was scheduled and the crew arrived on time ready to get things done. I described them like a well-practiced pit crew. In short order, they had a parts list completed and a Dave was off to get parts and complete some fabrication of custom pieces. I was thrilled at how quickly and thoroughly the work progressed throughout the day. By evening, the entire job was done. Full HVAC replacement, old units carted away, all new grills, and all new ducting, including increasing a 12" to a 16" and a 5" to an 8" at the base. Solid, clean and precise cutting and drywall work. Custom installation of the AC unit involved running electrical, copper, and creating new access points from the exterior. All done well and with precision. Each component was checked to be in good working order before they left. Very professional crew - competent, efficient, and respectful of our home. Highly recommended to anyone who needs the job done right. It's a great feeling to know we'll have reliable, quality heating and AC for many years to come. read more

See all

So far this guy is outstanding! Keith called me back within five mins and spent the next ten troubleshooting my issue over the phone. Once we figured out the issue was above my knowledge level he was more than happy to accommodate my schedule. Phenomenal customer service! Sorry this is late. Update: A lot of small businesses in the area could learn something from Keith. He goes out of his way to explain and teach his customers about HVAC systems. He goes well above and beyond to accommodate his customers schedules. Shout out to Jake, one of his tech's, he was just as awesome as Keith. I have already recommended Keith to some friends and he is the only HVAC service I will use in the future. In short...Outstanding!!! read more

I can't say enough good things about this company, and Keith himself. Last year our a/c went out in the dead of summer. I called several companies, and no one would come out right away. Keith came that day, scheduled the work for the next day - and did a great job. He was super busy, but went out of his way to solve our problem. Yesterday my tenant in the rental house we have, said the a/c was leaking, and not working. Once again, Keith to the rescue!!!! This man is a saint. So rare to find an honest company, who cares about their customers. Do not hesitate to call Keith Heating and Air. read more

Best customer service ever. Very loyal, responding for my service. My AC was not blowing in cool air and they were here in a hour to fix it. I'm so glad I called them and now my house is cooler. Thank you Keith for your service. read more

Bought a furnace from Keith 4 years ago. Fair price, quick installation. Today there was an intermittent issue and the furnace was cycling on and off. It's Saturday and the temperature is in the 40's and raining and it's after business hours. I left a message and Keith called me back within 2 hours and came my house at 6pm! Imagine the owner of the company showing up on Saturday night. He quickly diagnosed the minor issue and now we're sweating again, since that's how the wife likes it. THANKS KEITH!!! read more

I can't thank Keith and Johnny enough for making sure they got to my house the same day I called. Keith is simply the best. They fixed the a/c unit in ten minutes and even played with the dogs. I highly recommend his service. read more

My A/C wasn't cooling the house down so I called Keith. To my surprise he made it to my house the very same day and fixed the problem in about 10 min and didn't change me. He said it was an easy enough fix and not to worry about it. Keith is very friendly and knowledgeable! If you are looking for an HVAC company with integrity Keith is the man!!! read more

Thanks for coming out so quickly! Called the day before and he said he would make it out the next day. You often hear this and people don't show. He showed up on a Sunday afternoon. Fair prices too. read more

Keith's service was so amazing! It is one of the hottest days and our AC stopped cooling. He came within an hour, checked everything, explained what was wrong, and was extremely polite and professional. He did not try to upcharge us!! We will definitely be his regular customers now and would recommend his service to anyone. read more

Kieth, Thank you very much for you help! My dog ripped an electrical cable for my AC unit and I called a local contractor in SIMI (thank you yelp!) ... Keith came out to fix the original problem and ended up finding that the work completed by my home warranty company wasn't complete at all.. Long story short, he fixed both my problems and got my AC working the same day. I'm very happy with the service. read more

We called Keith Heating & Air Conditioning and were ready to have them come out and fix our heater/furnace...Thank you so much Keith Heating & Air who returned my husbands call within 10 minutes and for helping him over the phone! Really appreciate it! Will definitely use your company when service is needed!! read more

After dealing with another company that overcharged us and never fixed our AC we called Keith. They agreed to meet late so I didn't have to take time off work. They diagnosed the issue quickly and fixed my AC on the spot. No up-charges, no hidden fees, no nonsense. I won't hesitate to call them again if I have an issue. read more

Keith did the initial inspection of the HVAC system before we bought our home in Simi Valley in 2014. From the moment I met him I knew I had found our HVAC "guy". He gave us a no nonsense and practical assessment of the system in the home, and what was right and wrong with it. Fast forward a year later (2015) and our AC system had run out of refrigerant. He mentioned that most likely this would happen again if there was a serious leak and suggested a low-cost sealer as an experiment to avoid replacing the entire system. In 2016, the same situation happened again with the refrigerant, and Keith basically told us, you can try to find the leak with your existing system which is costly, or just replace it. We opted to replace both our air conditioners with Keith HVAC, who gave us a great deal. One was ancient so it was time. He fixed everything that needed fixing from the initial inspection way back in 2014 and we have been smooth sailing since then. We use Keith, our friends use Keith, and YOU should use Keith too... Period. I will mention also that Keith and his team are EXTREMELY responsive, always. In a pinch you are never waiting or hoping for a call back. Seriously good customer service. read more

I called them to come look at my AC and they were here within a few hours. Very fast, very friendly, fair pricing!

Our ac stopped working. Keith was at our house that morning on a very hot day to fix it. He correctly diagnosed the circuit board was bad. He brought a new circuit board that day and altered circuitry to make it work. However, Keith failed to diagnose the reason the circuit board went bad in the first place. I called a different technician who blew out and fixed my leaky pipe. If I hadn't called the other technician, I would have likely had to call Keith again soon to replace my circuit board again ( another $500). Keith also incorrectly diagnosed that the fan was going bad. The second technician indicated the fan was not bad. Good service. Very friendly and prompt. Good immediate fix. Bad diagnostician. read more

It does not get any better than this..... They had 30 minutes between calls on a fully booked set of appointments for today. As luck would have it, we are in the middle of a heat wave, the A/C is out and "Dave" said "I can stop by to look at it if you have a few minutes right now as I am enroute to my next appointment and you're on the way to my next appointment, 25 minutes from now. Bingo ! I do have an electrical background but not active and current on HVAC, I was pretty sure I knew what it was, but I needed an expert to confirm it. Dave, from Keith sure enough confirmed it AND had the part on his truck. He was in and out in 20 minutes. Man that is SERVICE. We're back on the cool side of things again in this 100 degree plus day. THANKS to Keith HVAC and a big THANKS to DAVE who I had a brief discussion with about my suspicions. He tested all the circuits and he tracked down the 24V input problem, in no time he fixed the problem! I highly recommend these guys, they could have easily driven by on a day like today and said I'll see ya in 24 hours. BUT THEY DIDN'T. APPLAUSE, APPLAUSE and again THANK YOU guys! read more

We had, not one or two, but three different problems occur with our air conditioner this Summer. Not knowing any good AC services in the area we looked on Yelp for a good recommendation. Immediately we saw Keith's service rated the HIGHEST, so, of course, we called him up... His receptionist answered, we told her the problem, and next thing you know, Keith is at our house FIXING the issue... Keith's response rate is SUPERB and his service is IMPECCABLE! You tell him the issue and he gets right in there resolves. He even provides you with GOOD tips and INFORMATION on how to maintain your unit. If he sees that you may not be maintaining your unit properly, he won't beat around the bush, but he'll tell you straight forward what you need to do. Keith is HONEST, FAIR, and highly RELIABLE... The second and third time we had an issue with our AC he was back at our house IMMEDIATELY working on fixing the problem... Keith's partner, Tim, was just as INCREDIBLE as Keith; knowledgeable, friendly, and honest... We feel very fortunate to have such a superb business in our home town... Thank you Keith for your hard work and service. read more

My heater stopped working over the weekend and and i could hear a loud buzzing coming from the main unit. I called a few places first thing Monday morning because it was cold in my house for a couple of days and right in the middle of a cold snap (34 degree nights) and I needed the heat fixed ASAP. Keith was the first to call back by a long shot and had arrived before I'd heard back from any others. Keith located the part for my 30 year old Lennox (not cheap mind you) and had the heater working very well before 4:30 pm the same day. He also replaced the filter and some other stuff too. Fast, professional and reliable. I year warranty on parts and labor. I felt like i was in good hands and when the time arises I'll call Keith Heating and Air Conditioning. Its nice and toasty in here now not like a meat locker :) read more

Fired up the A/C yesterday and the house fan blew, but no A/C. Checked the thermostat, checked the fuses...nothing. I called Keith heating and A/C about an hour and a half ago. The office forwarded the call right to Keith, who was in the field on another call. I explained the circumstances and he said I got him at the right time, he would be there in a jiffy. Less than an hour later he was at the front door. He gave the A/C unit a once over, checking the electrical signals, then pulled the fuses (the same ones I had checked) and showed me what the problem was, a blown fuse. Being the knucklehead I am, I had looked right at it and not recognized it as being blown. He popped and couple of new fuses in and gave it another once over. Good as new. Paid for the service call ($75) and a couple of fuses, got out of there for under a bill..... It's good to be alive at this point in human history, with that sweet cool breeze blowing at the back of my neck. read more

These guys are great! It was a last Friday night when I noticed it was getting warm in the house. I checked my AC and found it was not turning on like it should. The compressor would only stay on for a few minutes and turn off. It would repeat this over and over and not really cool the house. I checked on Google and found Keith Heating and Air Conditioning. Saturday I called and they said they would have somebody out within an hour. The tech, Dave, showed up at my door and quickly got to work. He determined I was low on coolant and possibly had a leak. He recharged my system and put a leak sealer in at the same time. The whole process took maybe a half hour and my system was back to cooling as expected. The cost of the coolant and sealant was reasonable to me. These guys are who you need to call if you need a repair for your system. read more

So our air conditioning broke down on a Friday. We called another local company to come out and the gentlemen that came out was very nice and didn't charge us for the diagnosis. However, the quote he provided was higher than we were comfortable paying. My hubby & I decided to look on yelp for some other options. We found Keith and called him up on Sunday. He came out same day, gave a lower quote and called the very next morning to schedule a day for the work. He came with his guys on that following Tuesday and BAM were back up and running. Our air is working wonderfully! Ahhhh how I love the cold air coming through those vents : ) Keith is also a very nice guy, was telling me about his family. Overall I am SO glad we found him and didn't settle for the first quote we received. Go with Keith! He knows his stuff, he's affordable, he gets the job done quickly and accurately. Plus, he's a nice guy to chat with. Hope this review helps :) read more

By far one of the best experiences I've had. Keith came out on a Saturday after 2 days of no AC and 100+ degree weather. I called many other places who either blew me off or said they couldnt see me for 2 weeks. Keith showed up (on time!) and diagnosed my problem within 15 mins. While another company told me I needed a completely new furnace ($4000), Keith said it can be fixed by just changing out the control panel. From my first phone call, I felt an immediate trust talking to Keith. He is very knowledgeable, and straightforward and I felt he had my best interests in mind. I would recommend him highly and if I unfortunately have another problem, he's the guy I'm calling!!! Jennifer read more

Called the contractor that installed my AC unit, MLP in Moorpark and never received a call back! Nice.. I hate that!! Called Keith and his answering service answered right away. I explained my issue, no AC and it was in the 90's and she connected me to Keith immediately. Turned out he was nearby, showed up in about 20 min! Found the problem, had the part, repaired it and stuck to his very fair quote!! Thank you Keith! You Rock!! read more
