Honest Recommendations

If a heating/cooling combo unit stops working properly, your home can lose both heat and cooling performance at the same time. PHD Heating & Cooling provides professional combo unit repair, performed by licensed and insured HVAC technicians skilled in servicing all major brands, not just Carrier.

We repair combo systems from:
Carrier, Bryant, Trane, Lennox, Goodman, Amana, American Standard, Rheem, Ruud, York, Heil, Payne, Comfortmaker, Coleman, Tempstar, and other manufacturers.

Common heating-related combo issues include:
• weak or insufficient heat
• no heat at all
• blower failure
• ignition problems
• sensor or control board issues
• refrigerant imbalance affecting heat pump mode
• unusual noise or vibration
• airflow inconsistencies
• system short-cycling
• thermostat communication errors

Our diagnostic process is detailed and accurate. На відміну від “об’ємних” компаній, які намагаються швидко “продати нову систему”,
ми шукаємо справжню причину несправності і виправляємо її професійно й чесно.

We use OEM-quality parts and follow manufacturer-recommended repair procedures to ensure long-lasting results.

We serve Chicago (West Loop, Lakeview, Lincoln Park, Bucktown) and suburbs (Elmhurst, Wilmette, Northbrook, Palatine, Glenview).
