"The owner Jerry came out quickly when we called, he was friendly, and did a thorough job testing and explaining what he offers. After getting a quote from him and one other and doing my own research and water testing, I found Jerry to be more accurate with my research and testing. His quote was reasonable, and he listened to what I said I needed and wanted. I would highly recommend this company. Not to mention his people were out within just a few days to install my water system. They were polite and respectful."

"Mr. Michael Brown, proprietor and plumbing expert, replaced two toilets, fixed a third (water supply valve and tank innards) AND installed a new water pump within our crawl space in less than an afternoon and within his time and cost estimate. Work was clean and performed efficiently and conscientiously. I would recommend Mr. Brown without hesitation and have additional projects lined up for him."

"We got the water softener system and the RO installed by Zach from Quality Water LLC. Zach was very detailed and helpful in explaining each and everything he was doing and educating us about both the systems. I am very happy that we went with Quality water as we got quotes from other vendors like Costco and all and they were really really expensive. We are really enjoying the soft water for our house and the purified drinking water."

"The estimator/sales person and technicians were top notch. The estimator worked with me on the system requirements and the cost of a new heat pump system. My old system was 20 years old so that the heat pump and inside air handler had to be replaced. Also replaced the thermostat for good measure. The technicians did an excellent job with the install, neat and professional. The system has been working really well. Overall, I believe that I received excellent service at a reasonable cost."

"Appleton Campbell just did a complicated 2-day gas furnace/AC unit installation attached our home. It was, probably, the most professional and well-handled vendor experience I have ever had, particularly with some complications that occurred due to things found after the old system was removed. From the sales process to the pre-project staff to the office staff who alerted me each time the crew was heading to my home, to the on-site crew of Mike W., Danny R. and Jake A., the experience was A+. Even when the one issue was presented, they came up with a solution and I remained confident they would. They were extremely clean and neat, during and after they were done. I did getting three bids for this and they were slightly higher than the others, but I felt more comfortable and frankly, I believe I got my moneys worth as they also had to fabricate and redo a complicated return and vent line, and they also moved the gas line, refrigerant line and other conduits/poles/switches to a more convenient area than with my prior (similar but older) system. In short, I felt like the value was there. They also included a Home Savings Agreement for one year and left me with a consolidated notebook of all relevant documents. Cheapest is not always better, and with all they did, the pricing was very, very close. I've known AC for years in the community, but only used them on a couple of occasions. I've become a huge fan and will use them again (I have other systems!)."
