"Everything done exactly right, on schedule (ahead of what I was expecting). AJB quoted a Columbia boiler, which cost a little more than the others, but I believe will be worth it. Worked almost 13 hours the first day and a couple more the next day to get the job done. Cleaned the area and ensured everything was operating properly."

"Perfect! Doug is an expert Plumber that knows private water system. He removed the old equipment and installed the new. Everything is still working great. The work was done almost 13 years ago. We used all Top of the line Gould Equipment. I probably should call Doug to replace it again because breakdowns with the water system can leave you stranded."

"Donny and Phill arrived on time installed floor protection and shoe coverings and did an excellent job in far less time than I expected. I would recommend Tri State for installation and maintenance of HVAC systems."

"Mis-diagnosed issue with Rheem AC unit. Diagnosed it as a refrigerant leak in the coil covered under warranty and recommended that I get in touch with the original installer to service the unit under warranty - which I greatly appreciated, and did. However, the original installer indicated that the unit was just a pound low on refrigerant - no leak in coil - and behaving as it did due to safeguards built into the unit to prevent damage to the unit."

"Excellent for both services! Technicians and consultant were polite and prompt. We enjoy Horizon Services’s customer service and work ethic. We can’t wait to switch over to our new furnace and AC unit once BGE installs the gas line to the house."

"Promptly returned email regarding service request, on Saturday. Responded same day to repair 2Ton Geo unit (Waterfurnace). Extremely knowable on geo-thermal systems, the repairs were made in timely manner at a fair price, my only regret on this geo unit is I should have had Continental install the system in the first place, it’s seems very likely I would not be haveing the maintenance issues."
