Best thing I ever did was call Mark One to install a new air conditioner in my home in Toms River. Mark and his dad did an exceptional job. I cannot write enough to tell you how incredible Mark is. The clean way Mark works is fantastic, the perfection of his work will be hard to match. He replaced my entire unit in the attic. I highly recommend Mark Osworth, owner of Mark One Heating and Air for all your heating and air needs. He is a true professional and you will not find a nicer person. I cannot thank him enough.

I had the pleasure of dealing with Mark during the rebuild of my home after Hurricane Sandy. Out of all the contractors there, by far, Mark was the best one. After the install of my new air conditioning unit there were some manufacturer issues. Mark was always there and never stopped until the issue was resolved. I could not be happier with his persistence in resolving the problem. Conscientious, caring, honest and just an out right nice person. I highly recommend Mark, owner of Mark One Heating and Air to anyone that needs heating and air conditioning work. After dealing with my contractor and many, many sub-contractors I can honestly say that they need to take lessons from Mark as to dealing with customers. He is the best example I know. Thank you Mark from the bottom of my heart!
