Cooling Repair That Restores Clean, Even Air

When a cooling system struggles, indoor air pays the price first: humidity climbs, certain rooms stay sticky, and a musty edge creeps in. The mechanical faults behind that are familiar to us — refrigerant low from a slow leak, a tired compressor, a failed capacitor, or a coil iced over because airflow dropped. We diagnose the actual cause and repair AC equipment from every major brand, including Lennox, Carrier, Trane, and Goodman, so your Yellow Springs home cools quietly and dries the air the way it should.

Heating Repair and Indoor Air Safety

Heating problems can affect more than warmth. PJ MAC repairs gas and oil furnaces, boilers, and heat pumps throughout Yellow Springs, and on every gas furnace we inspect the heat exchanger, because a crack can let carbon monoxide into the air you breathe. We address ignition faults, noisy blowers, and short-cycling, and if we find a safety issue we shut the unit down and tell you plainly rather than work around it.

Filtration, Humidity, and Healthier Air

A lot of what makes a Yellow Springs home feel stale traces back to filtration and humidity riding on the HVAC system. As part of repair and maintenance we check airflow and filters, and we service humidifiers, dehumidifiers, and indoor air quality equipment that keep the air balanced through the seasons. When a system is past its prime, we offer free estimates on replacement, with new equipment carrying manufacturer warranties; our technicians are EPA 608 certified for proper refrigerant handling.
