Omar was very helpful, knowledgeable, and timely, and was able to repair our AC unit in a matter of hours. Will definitely be requesting him next time. Thanks so much!

Chris B. came to my home to assess my 15+ year AC unit and furnace. He was extremely thorough, provided great diagnostics, and gave me all the options for repair and replacement. He was patient and not at all pushy, and would definitely recommend Chris and On the Mark for future heating and cooling services.
