In Memory Of HilCo Founder, Tony Hill

With 15 years experience in the HVAC industry, Tony Hill decided to dive into HVAC contracting and founded HilCo Mechanical Corporation in March 1989.

With Tony leading the way, HilCo went from a one-man service company to a team of 15 coworkers, 9 services vehicles, and thousands of happy customers resulting in numerous service awards.

In 2000, Tony was diagnosed with Amyotrophic Lateral Sclerosis (ALS), more commonly known as Lou Gehrig’s disease. Each year, approximately 6000 people in the U.S. are diagnosed with ALS, which is a 100% fatal progressive neurodegenerative disease that affects nerve cells in the brain and the spinal cord.

While fighting this devastating disease, Tony’s optimism and dedication to his HilCo team and customers remained strong. Sadly, Tony lost his courageous nine-year battle with ALS in August 2009. We miss him and will always remember him as the family man, honest businessman and loyal friend that he was. His commitment to the service we provide to our customers will never waiver.

In memory of Tony, HilCo employees take part in the annual event to support the cause to end Amyotrophic Lateral Sclerosis (ALS). Join us in helping create a world without ALS.

I trust the people at Hilco. They give honest advice with no hard sells. Hilco replaced my old HVAC and recommended adding a duct in the warmest room in my house. The comfort level increased in a big way and my APS bill actually went down and I have even temps all over the house.

- Larry D

I would give the HilCo team a 20 if it were possible! Always white glove customer service and extremely pleasant to work with. It feels so good to know that my AC needs are always being taken care of by a top notch team.

- Pam V

I have used HilCo Mechanical for all my A/C needs for almost 20 years. The service has always been excellent and I trust Brian to be completely honest with me. He has been excellent in keeping me aware when issues are detected, giving me a heads up. (This part is showing wear. You don't have to replace it now but I want you to be aware it will need replaced in the future and the estimated cost is $_.) I recently replaced my A/C and it was moved additional square footage from renovations. This required involvement by a trusted, qualified roofer and he gave HilCo high praises for the job they did!! I would highly recommend HilCo to anyone!!

- Judy
