“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.
