Lou Aretusi is a gentleman among contractors. In February we realized that our new home, built in 1927, had very poor heating to the second floor, so that the ground floor would be toasty warm while the upstairs was quite cool. As another reviewer said, it's hard to find someone who specializes in sheet metal work, but we found Dave White Heating on Home Stars and what a wonderful find that was. Lou came in and took a very close look at the existing duct system in the unfinished basement, answered about a million questions, was never rushed, provided some very helpful suggestions, then provided a clear and very detailed written quote that broke down in meticulous detail the different components of the work to be done and the prices. Everything we had discussed - up to the diameter of the different ducts - was there in the quote (it is by far the most detailed quote we have gotten, in 15 months of dealing with different contractors.) Lou really knows his business, and is exceptionally patient and congenial - he always answers his phone himself and is happy to answer questions. Ultimately, we replaced the main supply duct that services the whole house with a larger one, as well as four branch ducts that serviced the basement and upstairs, perhaps 60% of the ducts in our tiny home. We also installed two new ducts into the living room on the ground floor. Lou and his brother Marino performed the work in one day, and what efficient, cheerful, hard-working and professional gentlemen. Add to that list complete honesty, integrity, forthrightness, and beautifully executed workmanship and you'll understand why I say that if all contractors were like Lou, there would be no Holmes on Homes. (As a final note - the house is now toasty warm from top to bottom. This was a huge improvement for a very reasonable price!) A++
