"Woke up with no heat! Right before Christmas! Harris responded instantly and sent out someone to check the problem. Due to incorrect installation, rain had gotten into the improperly sealed roof vents, which in turned fried the transformer, inducer and circuit board. They were at my place bright and early the next morning installing a brand new furnace, more efficient and quieter, with a 10 year warranty. Arranged financing and were finished by 3pm. Everyone from my first phone call to the last service tech was professional, polite, knowledgeable and all around pleasant and really nice people. They will be my go to for heating, AC, plumbing and electrical from here on in. Glad I found them!"

"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."

"I needed repairs or replacement for a furnace at rental property. I submitted a request through Home Advisor, and within seconds I got a call from Frank. Frank visited the property the same day (10/16), and came back the next day to fixed the furnace. I spoke to the tenant, and she said she now has heat. Prior to contacting Old Skool I contacted a contractor who had done work on the furnace for the last several years. They advised me that the furnace could not be fixed and that they would not even consider repairing it. The only option the other company provided was replacement at almost a cost of $3,000. They also told me they probably would not be able to get parts for the furnace since it was so old. Old Skool found the part(s), fixed it, and cleaned it for less than $400. Thank you Old Skool for your prompt response and for saving me a couple of thousands of dollars. I plan to get Old Skool to check out the furnace in my other rental property."

"Mike is very responsive and I didn't get the usual upsell that I received from other businesses. He just fixed my furnace, explained why it would need to be replaced soon, and provided a clean quote for a system that met my needs."
