"My upstairs system (heat pump) developed a leak in the air handler coil. Rather than repair it since it was the original (17 years old), I decide to replace the entire system. Several companies quote. A-1 was competitive and after reading their reviews and researching the Brand (York), decided to go with them.
Great Choice!! The installers were excellent. A professional install, and they cleaned up when they were finished. When an wiring issue arose, Josh was called. He and another tech came out immediately and resolved it.
The new system is terrific, quiet, and provides more uniform heat throughout the entire upstairs.
I highly, recommend A-1. 5+++ stars"
