"Our service was excellent. Our technician, Brian, was on-time and thorough in his workmanship. He took the time to give detailed explanations of the potential and actual problems with our central AC unit and was very personable. We thought our system would need to be replaced, and he fixed it by replacing the compressor motor capacitor, saving us much expense."

"I had an Absolutely Fantastic Experience!! My husband & I were so lucky to have gotten Jason Scharf to come out to our home, he was very insightful, helpful, courteous and very professional. Jason explained step-by-step what he was doing along the way & what would work best within our home with 4 different price ranges that would work for us. Jason was very informative. He mentioned and advised me on some items that would require attention on a monthly basis which I was grateful for. Upon completion, he reviewed the bill and explained any questions that I had. I was very pleased. Overall, Jason’s work was outstanding. I would recommend Jason from Astar to anyone I know that is in need of a central air system in their home. He was one of the kindest, funny and coolest Design Specialists by far. Thanks again Jason you're the Best! We can't wait for everything to be completed."

"Owner showed up early (on time) to our appointment. Owner was very knowledgeable about the water treatment/purification business I had a water test conducted and I was presented my options. My experience was great and I did not feel pushed or sold into anything. Quote was significantly less than another competitor in my area. I would and have recommended Upstate NY water treatment to many people and friends looking to have their home water systems outfitted."

"I love my Culligan Twin Water Softener and AC-30 Reverse Osmosis. We have the best water available, soft water for laundry and bathing and great tasting Reverse Osmosis for drinking and cooking. The people at Culligan are wonderful. I would recommend this company to everyone. Quality products, fair price, and friendly service. I give Culligan an A+"
