Very grateful and appreciative of COSMOS (George) recommending a quality plumbing company to help us today with a drain overflow issue. I had contacted COSMOS about a water leak in our basement thinking it was related to our HVAC. George came our early this morning and assessed that we actually had a plumbing problem, not a problem with our HVAC leaking. He recommended 2020 Drain Cleaning and Plumbing. Of course we fully trust COSMOS to recommend great companies to us. 2020 came out this afternoon and did not disappoint. Their customer service and expertise were evident throughout. Thanks to COSMOS, we have a a quality Plumbing Company we can rely on. COSMOS always wants what is best for their customers. That is what sets them apart from all of the others. They deliver when others stumble. Thanks Georges, Gus, and COSMOS team!

I can not more enthusiastically recommend Cosmos. I first found Cosmos through positive reviews on Angie's list. I called when my AC was not working in summer. The first time I called, Gus was willing to come out on a Sunday to assist me. He was able to correctly diagnose my problem that 2 other companies missed. A few months later, I had a flooding disaster that killed/short circuited my whole AC unit. I was in-between transitioning to a new employer and funds were short. Gus was able to arrange a fair financing arrangement agreeable to us both. His pricing was very reasonable. Both Gus and his son take great pride in their work and do not take any short cuts. They are very knowledgeable and willing to answer your questions and concerns, providing superior customer service. I have had the misfortune of dealing with a national heat/cool company prior to calling on Cosmos. Don't make a similar mistake like me. Call Cosmos the first time, and you won't regret it. -Keith W.

I first called Cosmos during the winter of 2017. I just had moved to this house. The blower in the furnace was dead during the very cold days. George came out and replaced the blower. I was impressed and thankful because he understood my situation and came out as soon as he can. In 2018, I replaced the AC/Furnace. The other day outside condenser stopped working and Gus came out to replace the capacitor and it started working again. And before he was leaving he asked if there was anything else. I remembered I had a couple of flooding incidents. And Gus quickly saw that my problem was a blockage on my drain pipe. It took a little bit of work and managed it working again. When I was billed, I asked him that if I didn't have drain pipe fix, whether the cost would have been different. He said no, because he was charging me for the time (total time he spent was close to 1 hr). I think Cosmos is very professional and fair which is very hard to find these days.

We used Cosmos more than once and Mr. Gus did amazing job every time. They installed the new heater for us in our home. Mr. Gus do inspections on our cooling and heating system in our 2 homes in Alexandria every year and we can't be more happy with his professionalism and knowledge. We will for sure use Cosmos again and recommend them to all our friends.
