"Haller removed an old ac system and replaced it with a heat pump. The work included installing an additional return in the family room (split level home) to return air from the lowest point in the house. The crew was knowledgable, their work was neat, and they cleaned up at the end of the day. The work was completed in 2 days and the new Carrier system works great so far. Looking forward to see how it performs next fall and winter."

"I requested a ceiling fan install. The technician showed up on time. He was very professional, well mannered and got the job done in no time. I will definitely use this company again for future electrical needs."

"Horizon was completely professional and thorough. I had originally made an appointment with another plumber, but cancelled that appointment after talking to Horizon. The plumber who performed the work was excellent, told me everything he was going to do before he did it and made me feel very comfortable. I was quoted a price during the initial call and it was the same price I paid. I would definitely use them again in the future and would recommend them."
