“Heat pump failed to switch to cooling. Reversing valve was stuck. Replaced part and now mode switching is smooth and immediate.”
“We’ve only used Anthony since moving in 25 years ago. We’ve never been disappointed. He’s honest about repairs, never pushes unnecessary parts, and always provides stellar customer service.”
