"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."

"Pat gave me a great deal on a high performance boiler as a replacement for my 20 plus year old boiler. He installed the boiler and an indirect water heating system in the summer and he had to follow up in the fall to make sure the heater worked correctly. He did that and was very responsive to my questions while at my home and over the phone later. Pat was very professional and knowledgeable and I would use him him again and recommend him to others. Bottom line - Pat did what he said he would do!"

"Longacre is the best. I had an issue with my water heater. They contacted me so quickly, was able to get me scheduled same day and showed up within 1hr. By far the best. From the time they showed up they were very professional, clean and thorough. You gained a loyal customer. Thank you for your business."

"After signing up with Servicepro, I was on the phone with Horizon within 10 minutes. This was about 9:30 PM. They offered to come and fix the problem he next morning (day before Thanksgiving) but I declined because I was going away. Anyway I scheduled a 10 am appointment for Friday November 28, 2008 and they were very prompt. The techinitian expalined the issue and my heat was up and running within the hour. Very impressed with their service and professionalism. I am now signed up for annual check up for my HVAC system and would not hesitate to recommend them to others."
