Friday late afternoon, Maytag washer was not filling with water adequately. After running through the usual causal suspects, Constantine ran diagnostics. He figured out the problem. Gave me a price for the part and what the ETA would be. Part was expensive so he mentioned that if I wanted to think about it, I could let him know later. I would definitely use Kosmos Appliance and the star guy Constantine AGAIN ! ! ! He is prompt, polite, knowledgeable and easy going.

I highly recommend Konstantine as an appliance repair person. I appreciated that he responded quickly to my inquiry and was able to come out for repairs to my dishwasher within a day's time. His work was clean and professional. His communication was clear and pleasant. I was very comfortable having him work in my home. I will definitely hire him again.

Kosmos was on-time, professional, and able to come by quickly. He found the parts that would need to be replaced on our dryer, and helped us decide whether it would be worth trying to order those parts, as the dryer is more than 30 years old. Very helpful!

Cosmos did a good job was on time and kept us informed of the work and process. Pricing was fair.

Konstantin was very responsive and came out before the competitors. He immediately diagnosed the problem with our washer and offered two options for repair. We went with the more economical choice and when we encountered a problem, he promptly returned to troubleshoot and resolve. We are happy with the repair and appreciate his customer service.

had a wonderful experience with this refrigerator repair service! The technician was professional, knowledgeable, courteous, and arrived ready to get the job done. They took the time to explain the problem, answered my questions, and worked efficiently to get my refrigerator back in working condition. I truly appreciate the excellent customer service, attention to detail, and quality of the repair. It’s refreshing to find someone who takes pride in their work and treats their customers with honesty and respect.

Kosmos was extremely knowledgeable and professional. He identified the issues with my dishwasher and dryer quickly and was very sincere when he said there was no pressure to spend the money on repair if it made more sense for me to purchase new appliances. I truly appreciated his integrity and would love to refer him to others!

Highly recommend! He was on time, reliable, and communicated well, and fixed my broken freezer/ice maker for a lot less than I thought it would cost. I’d definitely use Kosmos again.

Kosmos was beyond amazing! He applied immediately to my initial query. Let me know ahead of time when he will be coming over. But the best part was that he spent over 1.5 hours trying to diagnose the issue with our oven. He found the problem and gave us an honest answer about the cost. Since it was an main electronic board that was no longer produced, he suggested and we agreed, it would be more affordable to purchase a new oven. He did all this for only an $88 service fee. I would HIGHLY recommend him. He is now our go-to service professional for all our major appliances. So glad we found someone of his caliber, professionalism, experience and honesty.

Kosmos was responsive, professional and knowledgeable. He diagnosed the problem with our refrigerator and was willing to repair it, but advised us that purchasing a new refrigerator might be the better option. We appreciated his honesty!

Great experience with Kosmos Appliances! He was professional, arrived on time, and quickly diagnosed the issue with my refrigerator. He clearly knows refrigerators very well, ordered the right part, and completed the repair efficiently. I would definitely recommend him to anyone looking for a knowledgeable and reliable refrigerator technician.
