Anthony has done an outstanding job servicing one furnace, replacing another and he's lined up for another replacement shortly (all on separate properties)! I would recommend him without hesitation!

I am absolutely thrilled with the exceptional service from AJ! I called in the morning for emergency heating repair, facing a critical situation with no heat and the risk of frozen pipes. AJ answered my call right away and swiftly made arrangements to visit, despite the treacherous road conditions due to heavy snowfall.

ALJ Heating & Cooling quickly answered our emergency no heat call. After discussing the parts and time frame needed to make repairs we decided on a new heating system. On Monday the new furnace arrived and by the evening the new system was installed and operational.

My wife and I enthusiastically recommend ALJ Heating & Cooling for heating/cooling service. Here’s why. Our AC system (5-ton) broke-down during a heat-wave; requiring an emergency response. We called ALJ based on the 5-star reviews, and true to these; Anthony (the owner) answered the phone and came by the next morning to assess.
