Told you need a whole new system? Get a second opinion first.
Several of our customers called after another company recommended a full replacement. We inspect the system, find what is actually failing, and give you a repair price next to a replacement price. You decide.
- Repair and replacement priced side by side.
- A clear explanation of what failed and why.
- Diagnostic fee waived when you hire us and we supply the materials.
“My parents had an HVAC issue where they called two different companies and both said to replace the whole unit. We decided to go for a 3rd opinion and contacted P&Y. It turned out to be a simple fix.”
“My furnace issue was misdiagnosed by a bigger company, so I decided to call P&Y for a second opinion. He immediately came to help and got my furnace blower running after a correct diagnosis.”
