“A few days ago after using the heat for the first time this season I woke up with breathing difficulties and having lived in a 4 floors house since 93 we knew that the ducts and vents were the culprits! Being ignorant and without recommendations I consulted yelp and proceeded to call; from beginning to end 5 stars is very merited. Claudio and the most gentlemen workers promptly arrived at 9 o’clock with price and approximate time agreed over the phone with Joseph. The short of the story is that everything including a very dirty furnace because of missing filters ….our troops had to work until after 7 ( twice the time) and respected the price and wouldn’t leave before the most perfects results accomplished ! Every grill cleaned, everything put back in place and extreme care to the environment ….we have beautiful pale wooden floors and staircases. Enough said lucky you will be to cross path!”
