Best Air Purification in Baltimore MD

Jonathon was on time, professional, knowledgeable, and up front and honest with the repair details and cost. I highly recommend Horizon to anyone who needs their services. Their customer service has always been incredible, which is rare these days. Excellent company to do business with!

Service provided: Flushed hot water heater. Good job. Professionally done.

AJ Michaels transitioned our boiler from oil to natural gas. They were on-time, informative, courteous, and completed the work in the expected window. Not only was the work professional but they went above and beyond to finish all the workspaces. They coordinated the new boiler delivery and city inspection as well. I would definitely use them again and highly recommend them.
