DML & S Air Conditioning & Heating

Donny and Russ are the most impressive professional — trustworthy people— to have ever done any work in our home.
I can recommend them easily —and highly— they are incredibly knowledgeable and so honest and you will feel like all of your most serious home-related HVAC issues are in the best of hands.
And for sure, they are completely reliable-and very nice as well!! I have been using this company for years and tell everyone I know how lucky we are to have found them.

Don is a true professional and has been serving Suffolk and Nassau for years!!! About 13 years ago he and his dad did a major repair and today Don returned to provide timely, honest and fair service to get my system up and running. Less than 24 hours I went from hot and sticky with my wife complaining, to cool and comfortable. Well done and thank you Don.

Donny from DML&S inspires confidence and trust. Made a great first impression when he serviced my mother-in-laws A/C ~5 years ago. I have used him since and recommend him to others without reservation. Why? Reliability, competency / quality of workmanship, neatness, and INTEGRITY. The icing on the cake is that Donny is a really nice person.
