Delta T Heating & Cooling - Philadelphia's Expert HVAC Repair

Our maintenance service is a thorough check-up designed to keep your system running smoothly and efficiently. We clean essential components, check refrigerant levels, inspect electrical connections, test safety controls, and calibrate your thermostat. For heating systems, we inspect the heat exchanger and burner assembly; for cooling, we clean the condenser coils. This proactive approach helps prevent unexpected breakdowns, improves energy efficiency, and extends the lifespan of your equipment.

Short cycling is a common issue here, often caused by an oversized furnace, a dirty flame sensor, or a clogged air filter restricting airflow. In Philadelphia's older homes, undersized ductwork can also be a factor. Our technicians start by diagnosing the root cause—checking the filter, thermostat, flame sensor, and heat exchanger. We'll provide a clear explanation and recommend the most practical fix, whether it's a simple cleaning, a repair, or advice on potential system adjustments to match your home's layout.

We offer installations for a range of systems to fit your home and budget. This includes high-efficiency gas furnaces and air conditioners, versatile heat pumps (which provide both heating and cooling), ductless mini-splits for homes without existing ducts, and traditional boilers. During a consultation, we assess your home's size, insulation, and existing ductwork to provide a tailored recommendation. We handle the entire process, from removing the old unit to installing and testing the new system, with warranty details provided upfront.
