Why Choose PHD?
When an air handler or high-velocity cooling system fails, airflow drops, comfort disappears, and energy bills rise. PHD Heating & Cooling provides professional repair services for Carrier air handlers, SpacePak, Unico, and all other major air handler brands — delivered by a licensed and insured HVAC team known for accurate diagnostics and clean, long-lasting repair work.
We repair all air handler brands, including:
Carrier, Trane, Lennox, Goodman, American Standard, Rheem, York, Ruud, Nordyne, Payne, Heil, and others.
For high-velocity systems, we specialize in:
SpacePak, Unico, and compatible small-duct products.
We fix issues such as:
• low or inconsistent airflow
• blower motor failure
• air handler not turning on
• excessive noise or vibration
• refrigerant coil leaks
• electrical or control board issues
• clogged drain lines
• poor air distribution
Our small, detail-focused team ensures repairs are done thoroughly and correctly — not rushed like large-volume HVAC companies.
