Klaus & Sons Plumbing
Heating & Air Conditioning

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!  

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!

We referred our neighbors. Andrew was very informative and nice.

I cannot believe how honest you guys are! Marino installed a new water heater, he was so helpful. He, Wes and Gene are awesome!

Tyler could not have been nicer or helpful. Very friendly and efficient. Good job.....Terry Morrison

Our technician, Charlie was at our home for a plumbing and repair issues Charlie did a great job and always kept me aware of time, etc.

Our technician was thorough and courteous and answered all of our questions. We are repeat customers.

A truly good plumber, excellent

Andrew was polite,  knowledgeable and we received excellent customer service.

Have had Gene out many times the past 3-4 years. Very knowledgeable. Stays on the job until he's satisfied. He helped me out of a heating problem caused by another source. Recommend him highly.

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

My water heater began leaking Sunday morning. I called a few places and received several outrageous quotes. I called Klaus & Sons and Sal was there within 45 minutes. He completed the job in a timely, professional manner and I was given a very fair price especially for a Sunday emergency. Thank you so much for a job well done!! Will definitely use Klaus & Sons for all my future plumbing needs.

Very efficient, friendly service. Thank you!

Our technician, Wes, was a happy hard-working, thinking tech. Clean, fast. We are repeat customers.

Service was very good, would call again, office was helpful and kind, clean. Very professional service.    

This job looked huge in my eyes; however, the outcome was SEAMLESS! THANK YOU!

As usual, excellent and friendly service.

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.

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 are very pleased with the work and all the workers!

Tiffany was great! Charlie was exceptionally good, if I had a business I would want Charlie working for me!

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.

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.

Wes asked good questions about our need for a replacement toilet and arrived at the time he promised. The work was well done, great attention to detail and the area was left spotless. In short, Wes maintained the high standards I've come to expect from Klaus and Sons.

A big thank you to Fred for fixing the cracked pipe in the wall/foundation off the main kitchen drain pipe the day after Christmas. It was a very long day, but he stuck with it and finished the job that day which I was most appreciative of. Price was fair, Fred was neat, professional and willing to explain things as he worked, Thanks again Fred!

Knowledgeable and efficient while trying to minimize any mess. Would call again.

Our technician, Tyler, was friendly and knowledgeable. Service was clean, fast and the office was helpful and kind.

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.

Fred was very dedicated to completing the job properly.

Very good service! We were well pleased. Tifanny was very helpful.

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.

As a follow-up to my earlier review, I want to say again how pleased I am with the quality of work and how great it is to work with Klaus and Sons. Junior returned with the air blower parts more quickly than expected. His repairs did the job and then he went above and beyond by checking temperatures at various points. He determined it wasn't as effective as it should, check the air conditioning unit and showed it was low. The whole time he was doing the maintenance he carefully explained everything, showing the readings and what they meant. Definitely calling Klaus and Sons when we are ready to upgrade and would be very happy to see Junior there again. Thank you.

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!

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.

Thank you Klaus and Sons. I want to say thanks to Fred as well. He came out to my house on short notice, helped me with a plumbing issue in my sink and we polite, trustworthy, and hardworking. Thank you very much!

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!

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.

Wes was very polite, professional and clean. I would call Klaus & Sons again.

Our technician was Fred. We were very impressed with the service, especially with Fred, who is very professional. You should be very proud of him he is a great asset to your company.
