Fantastic service, definitely recommend this company

Efficient, on time, clear - excellent service

I've never used there Services. I merely requested a price quote for a part but they failed to advise me.

HERE IS MY REPLY TO THIS MENTAL MIDGET'S COMMENTS: DID I HURT YOUR FEELINGS BY BEING HONEST? THIS ISN'T SOME BIG CONSPIRACY. IF I WERE A COMPANY, WHY WOULD I MENTION THAT I NEVER USED YOUR SERVICE? OBVIOUSLY, I WOULD NEVER USE YOUR SERVICE AT THIS POINT. YOU'VE LOST A POTENTIAL CUSTOMER AND MANY MORE ONCE I PUT OUT YOUR POMPOUS ARROGANT COMMENTS! I CONTACTED YOUR COMPANY TO FIND OUT WHAT A PART WOULD COST, AND THE BALLPARK FIGURE YOU MIGHT CHARGE TO FIX THE PROBLEM. I WAS (NEVER) GIVEN THE PRICE FOR THE PART, NOR THE QUOTE TO DO THE WORK. YOU FAILED TO PROVIDE THE INFO. PROBABLY BECAUSE YOU EXPECT TO CHARGE A LOT MORE AFTER DOING THE JOB. WHO ARE YOU TO TELL A POTENTIAL CUSTOMER THAT HE CAN'T POST A REVIEW? I'M NOT SOME SCARED FEMALE ALONE IN HER HOME. YOU CAN'T TRY TO INTIMIDATE ME! I'VE BEEN WORKING WITH THE FIELD OF FEDERAL LAW ENFORCEMENT FOR OVER THIRTY YEARS. IT SEEMS LIKE YOU ASSAULTED THAT OTHER CUSTOMER WHO POSTED THAT REVIEW ABOUT YOUR POOR SERVICE. PERHAPS I SHOULD BE INVESTIGATING YOU! I WONDER WHAT YOUR RECORD IS LIKE? DO YOU ACTUALLY BELIEVE BEING AGGRESSIVE AND TRYING TO BULLY CUSTOMERS WILL HELP YOUR BUSINESS? PERHAPS YOU DON'T UNDERSTAND. YOUR POOR GRAMMAR AND MISSPELLED WORDS ACTUALLY REFLECTS YOUR INTELLIGENCE.

I FOUND OUT THIS OWNER THOUGHT HE COULD REMOVE HIS POOR COMMENT THAT I HAD REPLIED TO. IT'S NOW HERE FOR ALL TO SEE!!!

They did a great job installing my HAVAC system. they also do good service work. I'm a big fan.

George and the team were excellent. Very responsive, came out and installed the new boiler very quickly.

Replaced heat pump in office. Excellent communication, professionalism and work. They even removed an old refrigerator for me at no charge just because I casually asked.

Efficient, great communication, good pricing.

Cosmos has taken care of my heating and cooling needs for the past few years. They do a great job of showing up when they're supposed to and not upselling me with extra services I'm not interested in. I'll be calling them again for spring service.

I sent a friend to Cosmos for some work. George contacted him quickly after the initial call, and they were able to get the problem resolved promptly and at a very fair price. These guys are the best in NOVA!

Gus and George have been taking care of me for years now. I have been extremely pleased with their response time, price, and level of professionalism. And I must mention that the book they wrote has already saved me money. 5 STAR SERVICE!

Cosmos heating and cooling not the largest as far as size but the biggest as far as customer service and care. Their prices are competitive.
Truly for all my heating and cooling needs they are my guys... I really recommend this guys.
Big companies place any rookie in a truck to go figure it out... after all that's how you learn right?
Not this guys they got ton of experience, they know their stuff.

Extremely rude and unprofessional behavior from the owner of this company. Cosmo became very loud and agitated and defensive when asked simple questions about the service estimate. He started raising his voice at me, asking me why I was looking at him as if he were here to steal from me and accusing me of having an attitude with him. I attempted to reason with him, but he continued his tirade, yelling even louder and saying that he was here on a Saturday and that I didn't appreciate his help. I then asked him to leave, so he started slamming doors and continued yelling how ungrateful I was. I did not feel safe or comfortable with this individual and would not recommend his services.
