Heating System Repair Services

At Denillo Heating & Cooling, we take the winter season in the greater Pittsburgh area seriously. We understand that a heater that can’t keep everyone warm in icy weather poses serious health and safety hazards.

Whether you need a furnace repair to protect your family from shivering or a heat pump repair to keep your commercial enterprise open for business, we provide emergency repairs 24/7. We’re readily available for less urgent situations as well. Call us to schedule repair services at the time most convenient for you.

Heating System Maintenance Services

Whether you own a home or manage a business, your heating system represents a substantial investment. Our preventive maintenance services not only protect this valuable asset with regularly scheduled tune-ups, but also provide peace of mind. During each pre-scheduled visit, we’ll inspect every component of your heating system to ensure everything runs smoothly, safely and efficiently. Your heater will last longer, perform better, and expend less energy with proactive maintenance from our experienced service technicians.
