Our Testimonials

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!!
