Our technician, Tyler, was friendly and knowledgeable. Service was clean, fast and the office was helpful and kind.
Tiffany was great! Charlie was exceptionally good, if I had a business I would want Charlie working for me!
Got a quote from John to replace our AC system right after our scheduled inspection appointment. He is very knowledgeable and steered us to the right equipment based on our use, without overspending on the "bells and whistles", and he is not pressuring us to make the decision. After we decided to go with Klaus & Sons, John was able to send a crew for the installation within 2 days, and he sure picked a good crew to work on our unit. Kevin, Tom and their assistant showed up at our house as scheduled and did a wonderful job on the installation. They took care in protecting the work areas, did a professional installation, started the unit and adjusted it to run perfectly. All the rooms are now cooled down evenly both upstairs and downstairs. These guys did a great job that we even recommend them to a few friends and co-workers.
We have Lennox HVAC, and had disappointing experiences with three other Lennox dealers. Gene is by far the best technician we've worked with--very knowledgeable and helpful, and glad to explain ways we can get the best service out of the equipment. He sets a high standard of excellence.
I cannot believe how honest you guys are! Marino installed a new water heater, he was so helpful. He, Wes and Gene are awesome!
A truly good plumber, excellent
Our technician, Wes, was a happy hard-working, thinking tech. Clean, fast. We are repeat customers.
We've been in our home for over 50 years and have used Klaus & Sons many times. They are reliable, fast and that kept this old house in tip top shape. I definitely recommend them to my neighbors and friends.
Very efficient, friendly service. Thank you!
Fred was on time, friendly, and professional. He thoroughly checked everything out and explained his assessment clearly and completely. Fred obtained the parts needed and finished the job the same day. I've had work done by Klaus and Sons and I am completely satisfied again. The service you provide is excellent.
We referred our neighbors. Andrew was very informative and nice.
I called on a Saturday afternoon for an emergency water main repair. The receptionist was very courteous and polite and I received a call from Fred within 15 minutes. Fred was able to assess the situation and made a repair on the spot (I had already dug up the main). Once repaired, he made sure the fittings had cured before turning the water back on. Overall, excellent service!!! Couldn't ask for better! Thanks!
Thank you so much all of your help. Your men are always on time polite and kind. For 25 years you've never let me down.
These guys are a class act. Not only have they helped me fix any number of plumbing issues around the house but I also wouldn't be anywhere near as cool as I am thanks to to their air service. I'm a drywall contractor too and have done a lot of business with these guys over the years and know them to always look out for their customers first. It's a family business run like it will be passed through many more generations. Everyone there is so competent and if you meet Klaus you'll get an idea how this place stayed in business for 40 years. You can't go anywhere without seeing their trucks! Old school business values, family business and top notch craftsmanship means you can send these folks to your moms house without worrying about them trying to get rich on one job. Like I said in the beginning, Klaus and Sons, Danny, Jesse , grandson Chris and all their other top notch journeyman are class acts!
This job looked huge in my eyes; however, the outcome was SEAMLESS! THANK YOU!
Andrew was polite, knowledgeable and we received excellent customer service.
As usual, excellent and friendly service.
Our technician was thorough and courteous and answered all of our questions. We are repeat customers.
Dear John and the great crew at Klaus & Sons, thank you so much for a great job. Well done. I appreciate you being on time, neat, polite and friendly-what a hard-working crew!
Fantastic people to have your work done. Fred and Andrew were great, along with the rest of the crew!!!. They were hard workers, polite and they cleaned up after themselves. Fred even had to come back to the house after working 8 hrs. for a minor glitch....he is wonderful!!! An awesome company to deal with!!!! Thank you all so very, very much, we all appreciate what you have done for us and will Highly recommend you to anyone that needs your kind of service!!!!
Just a note to express my appreciation for the exceptional service I received from Gene. He was very thorough but what impressed me the most is that he took the time to explain the details of the service process and what each part of the equipment does and what I need to do to extend the life of my AC/heating units. He never appeared rushed. It was a real education watching him perform the service on my two units. Without question, Klaus & Sons will forever maintain my AC/heating units, special thanks to Gene!
Fred was very dedicated to completing the job properly.
|We had a bathroom remodel done on our old home. Dan and his team are 5 stars, all the way. They are professionals that are happy people and proud of their work. You can't find workers like them anymore. I want to thank Klaus & Sons for the great remodel and it was totally done in only 3 weeks. Their prices are fair and the work is perfect! Thanks Again. Nancy W., Rancho Cucamonga|
Thank you for taking the time to take care of us on a Saturday! It was a big help and we really appreciate it.
To the whole team at Klaus & Sons, THANK YOU I am sorry I did not have the opportunity to meet any of you when you came and did our installation, but my wife could not contain her excitement with what a wonderful job you all did at our home. Great work, you are very much appreciated.

Klaus & Sons continues to take excellent care of all our plumbing needs, as they have for decades.

Fred was professional and courteous. Thank you for traveling to Mt. Baldy, it is appreciated. The service was very good, fast and the office staff was helpful and kind.
Knowledgeable and efficient while trying to minimize any mess. Would call again.
“My husband and I were tired of the inefficiency of our AC. While the unit itself was operable, the system just wasn’t working for us. We were constantly scrambling for ideas to make our home more comfortable but keep our energy costs reasonable. At around the same time we decided to replace our taxed water heater we decided to look into having our attic insulated. We had a couple of quotes on the attic insulation and I felt like the bids sounded “gimicky” trying to sell us services and products I didn’t really feel that we needed. My husband thought of Klaus and Sons and made the call (at around 5:30 PM no less) and they were out the next day. John listened to our energy concerns, got a feel for what we really needed, surveyed our attic, and talked with us about our options for a solid two hours. His knowledge and expertise was absolutely unmatched. Literally unmatched, not a single contractor explained or suggested the solutions that John laid out for us. We were so comfortable with the solutions that he suggested that we signed the contract immediately. Klaus and Sons, removed our old duct work and replaced it with updated, insulated, properly- sized ducting, redesigned our system to properly circulate air throughout our house, thoroughly and properly sealed all of our walls and attic space, and insulated our attic. Oh, and they even installed a new water heater for us! Each person who has worked in our house throughout the process has taken their time to do the job thoroughly and correctly. They absolutely pride themselves on a job well done and it shows. They have worked tirelessly, neatly, and efficiently, but I’ve been most impressed with how well they all work together. This is a company that operates like a well-oiled machine. Everyone communicates clearly, they have a common goal of satisfaction for a job done right. We’ve been hugely satisfied with the work that Klaus and Sons has done in our home. Thorough is the best word I can use to describe the manner in which this company works. They have worked above and beyond the scope we expected. We’re not only pleased with the level of skill, professionalism, and expertise of Klaus and Sons but we’re almost indescribably more comfortable. There is a measurable difference in the way that our AC system operates. Our house is cooler, more comfortable, the airflow is vastly improved, and the system is running smoother and more efficiently than ever before.
The only thing I regret about this process is the money and the time we wasted before realizing the magic that Klaus and Sons delivered.
***I would be remiss not to mention that mid-AC improvement I asked if they might be interested in removing our fireplace and opening up our house a bit. This was previously only a dream to me. The fireplace was nothing short of a monolith. It was a huge, solid rock structure. Not like the type of rock fireplaces you might see in a cabin, not a rock facade, these rocks were huge. Floor to ceiling with cantilevered concrete hearths on each side (yes, it was a two-sided beast) and about twelve feet across opening into the living room and kitchen. While interesting and unique, it really never suited the style of our home and was also non-functional as it had no damper/flue and only filled our home with smoke on the few occasions we opted to use it over the years. We’d discussed cosmetic options previously and even consulted with concrete/masonry contractors to see if they might be able to improve, if not remove, it. It seemed insurmountable to us for so long. When I asked John whether it was something they might be willing to tackle he responded that while it would be a job that it was nothing they couldn’t handle. They handled it! The difference is amazing; we now have better airflow, more open, updated, cleaner, and just a completely improved state of our home.”
I was very happy with my experience with Klaus and Sons, I had my water main changed from the meter at the street to the house. They showed up when they said they would and we’re done when they said they would be. The crew was incredibly nice and explained to me exactly what needed to take place………
Thanks for the great work Dan, I like that my water is no longer rust color.
What an amazing guy John is!! I called to get my AC looked at because it wasn’t working. He was able to come by the next morning. Unfortunately, my problem was I needed an entire new unit and I can’t afford it right now. John was so kind and sympathetic to my problem he didn’t even charge me the fee for coming by to look at it! I can assure you that when the time comes for anything else Klaus & Sons can help me with they will be my first call.
I was in the market for a new air conditioner & furnance replacement. After receiving 5 quotes my mind was stuck on the 2nd quote I received which came from Klaus & son thru Costco for many reasons. 1)No pressure or timeline for price to expire 2) one of few who was an actual tech & not a sales rep that shows up 3) did not degrade any other companies. During the install I had a few issues come up and each time I thought I’d get push back or I’d have a fight on my hands, NO that wasn’t the case. I have to say everyone whom I dealt with was “professional”. I do highly recommend klaus& son even if it’s just to give you an estimate. Thank you….John, Kevin, Junior and Dan
You don’t find customer service like this anymore so hats off to you Klaus & son (Dan)
I had Klaus & sons install my air conditioner and heater. After many quotes they provided the best quote. They were very professional, courteous & knowledgeable. Some the other quotes were extremely high along with aggressive sales tactics which I did not appreciate. Not Klaus & sons. They were in and out of my home very quickly.
Sometime later, I needed a new water heater. I did not think of them first. Again I called around & ended up buying one from a national dept. store. Even though I paid for delivery & installation, the guy who delivered it insisted upon an additional $500 to install. I sent them packing and called Klaus & Sons. I did not think they did water heaters. I called & spoke with Jessie again. He said they do sell & install water heaters. He came right out & gave quote. It was installed by the end of the day. I wish I would have called him at the start. I always call them take care my heating & air conditioning needs. Their customer service is amazing, I can always count on their quality of work.
