DML & S Air Conditioning & Heating

I have used DMLS for my previous home including a hot water heater install. And my most recent purchase of a home to have a heating unit and central air condition unit installed. Sal and Donnie are not only professional in their work, but they are reliable and super neat with all that they do.Having workers that you trust in your house is so important to me!

We recently purchased our first home early last year. It is a historical home built in 1920s, in which needed some moderate updating. One of which was our boiler that we wanted to convert from oil to gas. Since this being our first home and an older home we contacted many Long Island larger companies to find out what it would cost us and what it would take to convert as well as making our home more energy-efficient. After speaking with some of the larger companies we were not at all impressed nor did they offer us the quality work we needed to last us 20 years plus. We reached out to some friends for help, this is when they recommended Donny. Right off the bat Donny was informative upfront and told us step-by-step what our options were. We soon realize that the larger companies were clearly gouging us and we were not going to be as efficient as we needed.Once we decide to go with Donnie and his company we realize we made the right choice. Donny kept communication lines open during the entire process, as well made sure that all the tedious paperwork was filed and done. He came in with his master plumber, who redesigned our manifold and zones. Scott the plumber's work is beyond impeccable and clean. He is simply a master plumber/artist in what he does. This without a doubt has increased the value of our home.While my wife works from home it was very rare for me to feel comfortable with someone that was working in our house alone with my wife. And after meeting and speaking with Donny and Scott I realize that this was no problem at all. These men are simply good and honorable and their work shows it. If anyone of my family or my friends needed a plumber or electrician I would without a doubt hands-down recommend Donny. We will be using them again in the future for a cooling system. Thank you for for all your hard work.
