"Tom, who was highly recommended to me by a Hillside customer, proved to earn the high recommendation. I recently had a different company advise me if necessary heater repairs with a cost of over $5,000. Tom listened to my concerns and then carefully examined my heater confidently displaying his experience and knowledge. He then assured me my heater did not require the repair. My sincere thanks to Tom and Hillside for being trustworthy. Be assured that I too will be recommending Hillside. "
