"George arrived promptly, spent time meticulously cleaning all heater components, explained what was needed and why ( voltage measurements, etc.), even measured the heater's CO output (which was ok). Great job. Will definitely use him for my pre-summer AC inspection."

"Duane was great. He came out and figured out the problem with my heating system (noisy and shaking). He fixed the issue for a very reasonable fee and explained his other products and services without being the least bit pushy. Would recommend their services."

"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."
