Pasadena is a historic and beautiful city known for its iconic Craftsman homes, stunning architecture, and cooler winter temperatures that make a reliable heating system essential.

Call us today at (833) 581-1178 for emergency heating repair.

For Pasadena’s historic Craftsman and Victorian homes, the most common heating systems are older gas furnaces, often original to the home or installed decades ago. One frequent issue we encounter is a faulty thermocouple. The thermocouple is a safety device that detects whether the pilot light is lit. If it malfunctions, it shuts off the gas supply, preventing the furnace from igniting. This results in no heat at all. Our technicians can quickly test and replace a faulty thermocouple, restoring heat to your home within an hour. Another common issue in older furnaces is a cracked heat exchanger — a serious safety hazard. Signs include strange odors (similar to exhaust fumes), soot buildup around the furnace, corrosion, or a flame that flickers or changes color when the blower fan starts. If we find a cracked heat exchanger, we recommend immediate replacement.

For homes with gravity furnaces — common in many historic Pasadena homes — we specialize in repairing these unique systems. Gravity furnaces have no blower and rely on natural convection to circulate warm air. They can develop cracks in the heat exchanger or issues with the pilot light. Our technicians are trained in repairing these older systems safely. For wall heaters, often found in smaller historic homes and apartments, we repair ignition issues, thermocouple failures, and blower motor problems.

For homes that have been updated with modern HVAC systems, we repair gas furnaces with electronic ignition. The most common issue we encounter is a dirty flame sensor. The flame sensor detects whether the burner has ignited. When it becomes coated with carbon buildup, it fails to sense the flame and shuts off the gas as a safety precaution. This results in the furnace cycling on and off repeatedly without producing heat. Our technicians will clean or replace the flame sensor, restoring normal operation in under an hour.

For heat pump systems — common in newer Pasadena additions and renovations — the most frequent repair we perform is addressing refrigerant leaks. Heat pumps rely on refrigerant to transfer heat from outdoors to indoors. When refrigerant levels drop due to a leak, the system loses heating capacity and may develop ice on the outdoor unit. We use electronic leak detectors to pinpoint the exact location of the leak — typically at brazed joints, Schrader valves, or coil connections. We repair the leak, then evacuate and recharge the system. We also repair failed reversing valves and outdoor fan motors.

Another common issue in Pasadena homes is faulty ductwork. Older homes often have ductwork that is undersized, leaky, or poorly insulated, leading to uneven heating and cold spots. We offer duct testing and sealing services. At Season Control, every repair includes a thorough system inspection.
