What Our Clients Have to Say About Our Services

Marlene Wentz

“Cal Tech Pump Well & Compressor saved me hundreds of dollars on my electric bill each month. I was paying over $800 per month for electrical service. I knew something was wrong but the many technicians I had look at my system couldn't find the problem. On Scott's first visit to my home he quickly discovered that an old pump down in a well not being used had been turned on and was constantly trying to start 24/7. In addition, he discovered that one of the "other services" had cut into my 2,500-gallon holding tank, allowing leaves and frogs to contaminate the water. He reworked the system using two existing pressure tanks instead of the compromised holding tank. This made my water safe and further reduced my electrical bill because I was only pumping the water once and not into the holding tank and then pumping it again into the pressure tank. I highly recommend Cal Tech Pump, Well & Compressor. They certainly did a wonderful job for me.”

Linden Reeves, Middletown

“We had just had a well drilled and needed someone to install a pump, but we didn't understand how much work it was going to be. The well was over 200 feet from the storage tank. Scott had the pump installed in the well within a day. The pipe to the tank was another story. The difficult trenching and the hidden pipes were all obstacles that slowed progress. Scott did a great job for us. He stuck with his original quote. We have been very happy with the installation. We've called him back once since the install and that happened to be our fault. I am sure there are other great installers out there, but Cal Tech did a superb job for us and we would call them back whenever we have a problem in the future.” 

Denise and Jim Comisky, Cobb Mountain

“We just wanted to thank you for your prompt, professional, on time and efficient installation of our water well system. When we called you and requested a bid, you showed up on time, you were prepared and provided us with a competitive bid when you said you would. This professional approach to your business is why we will use you for all of our future well development upgrades or repairs. As a lifelong resident of Cobb, I appreciate this sort of service.”

James Hershey

 “On the recommendation of my well driller, Larry Herman, I called Cal-Tech Pump Well and Compressor. I spoke to the owner, Scott Brown about my needs, and we scheduled a time for him to come out and discuss the project. Scott was very professional when I met him, and immediately impressed me with his knowledge and experience. I received a reasonable estimate within three days, and we completed a flat bid contract for the purchase and installation of two pumps, a 3,000-gallon tank, and a pressure tank, all controls and accessories needed, as well as all required plumbing and electrical work.

Scott arrived on time on the first scheduled day of construction, fully equipped with all of the necessary materials and tools. He worked quickly and efficiently, and it was evident that he had done numerous installations of this type in the past. He completed all work to my satisfaction in three days, and proceeded to assist me with a couple of connections that I had agreed to do as well.

I would unreservedly recommend Scott and Cal-Tech Pump Well and Compressor for anyone who appreciates professional, experienced workmanship. I believe you will be more than satisfied with the results.

Oh, and by the way, he’s a really nice guy.”

D. Chambers

 "Thank you very much for coming out on such short notice. Not everyone would come out on the day they were supposed to leave on vacation, just to make sure I had water. I really appreciated it. You did a wonderful job. I will recommend you to everyone i know. Again thank you for everything.”

Marty and Claudia Kuchinski, Hops-Meister LLC

“On time, on budget, look forward to working together again. It is such a pleasure to have a call answered by a live person who actually has the answers to your questions. Cal-Tech has been a great resource for us. They know their products and their reliability, both in getting the work done on time and without additional financial surprises, has been a tremendous relief, especially during those chaotic times of the year when we don't have the time to monitor minute by minute that the job is being done properly. You can rely on these guys.”

Sandra West and Lora Tell, Edgewater Resort

“We are writing this letter to acknowledge Cal-Tech Pump for their outstanding

service provided. Over the last fourteen years we had been using the services of

another company located in Lakeport for all of our pump equipment, servicing, parts

and repairs. It's been an annual expense to upgrade and maintain these pumps

throughout the years. Like many businesses and residences in Lake County we use our

pumps for irrigation on our five acre property. 

In July 2008 when we discovered our system was not working properly we called our

service provided, to find and repair the problem. The first technician they sent

out could not find the problem. Two days later the owner came, found the problem

and repaired it. The system stopped working three days later. After returning two

more times over a two month period, the system failed again. 

We then headed to the local phone directory and started calling the few other

providers in Lake County. Cal-Tech Pump returned our call the same day and arrived

the following morning. The problem was diagnosed and repaired the same day. The

pumps fired right up this season and we had no problems at all this year.

Thank you for providing Lake County businesses and residents with reliable, speedy,

knowledgeable, efficient, and competitive pricing for your professional services.

Without hesitation we highly recommend Cal-Tech Pump.”
