Clark Services, Inc. of DE

In an industry filled with corporate franchises and revolving-door technicians, Clark Services stands alone as the true HVAC authority in Sussex County. I recently hired them for a full system replacement, and it was clear from the first consultation that this is a company built on elite technical expertise and family integrity.

Came home to no heat. Temp was 42 degrees in our house. The technicians arrived within an hour. Luckily not a major problem and they fixed it that day. John and Dylan were knowledgeable and friendly.

We just received excellent service from Clark HVAC. Dylan was very good with repair, explanations and promptness Clark response is exceptional when called. The staff kept us informed every step of the way. Have no reservation to recommend Clark HVAC of De.

John was outstanding! Came exactly as scheduled, he was professional, knowledgeable and honest. It’s rare to find such a gem. I really appreciate Clark’s and will always use them!!!

I just had my 35yo York AC & gas furnace replaced with a Rheem AC & gas furnace by Clark Services Inc. of Delaware, a local family owned company. Mark Clark and his crew & staff (John, Jack, Dylan, & Brittany) were so professional, knowledgeable, and pleasant to work with. Many kudos for a wonderful installation and at a reasonable cost.
