The short answer
Burbank heating systems often fail at the start of the cool season after months idle. We identify whether you have a furnace, heat pump, ductless unit or wall heater, test its controls, airflow and safety devices, and explain the repair before starting.
Heating systems in Burbank live a lopsided life. They sit idle through a long, hot Valley summer and then get asked to work every evening once the cool months arrive. That pattern produces a predictable set of problems: dust on burners and heat strips, igniters and sensors that weaken without warning, thermostats with dead batteries, and heat pumps whose heating mode has not been tested since spring. Climvanta repairs gas furnaces, heat pumps, ductless systems and wall furnaces across the 91501, 91502, 91504, 91505 and 91506 ZIP codes, about 13 miles east of our Tarzana base. This page explains how we approach a heating repair from the first phone conversation to the final test, what typically goes wrong with each kind of system, and when a repair is the right call versus a larger change.
Start with the type of system
The first question we ask is what heats the home, because the troubleshooting path differs sharply. A gas furnace has an ignition sequence and combustion safety controls. A heat pump has a reversing valve, defrost controls and possibly backup electric heat. A ductless mini-split relies on communication between the indoor head and outdoor unit. A wall furnace, still found in some older Burbank homes and additions, uses a pilot or simple ignition and vents directly through the wall or roof. Knowing which one you have, and where it is located, helps us bring the right parts.
Common failures by system
These are the problems we encounter most often in Burbank homes at the start of the heating season.
- Gas furnaces: cracked igniters, dirty flame sensors, pressure switch and inducer faults, limit trips from restricted airflow, and failing blower capacitors.
- Heat pumps: stuck reversing valves that keep the system cooling, defrost board or sensor failures, low refrigerant reducing heat output, and auxiliary heat that never engages.
- Ductless systems: clogged filters and coils in the indoor head, sensor faults, communication errors and drain problems flagged as error codes.
- Wall furnaces: pilot outages, worn thermocouples, blocked vents and clearance problems with nearby furniture or curtains.
- All systems: thermostat wiring faults, blown control fuses, and tripped breakers.
How the repair visit works
When you contact us, we ask about the system type, what you are noticing, whether any codes are flashing and when the problem began. On site, the technician confirms the thermostat is sending a call and the equipment is receiving it, then works through the system's operating sequence until the failure point is found. We measure rather than guess: microamp readings on flame sensors, refrigerant pressures and temperatures on heat pumps, static pressure in ducts, and voltage at motors and controls.
Gas appliances also get a venting and combustion check. We look for spillage, damaged vent connectors and gas leaks, and we recommend keeping any unit off if it presents a carbon monoxide concern. Before replacing anything, you hear what we found and what the repair involves.
Ducts and airflow in older homes
Not every cold room is an equipment failure. Many Burbank houses have shallow attics where ducts were installed decades ago. Over time, joints separate, flex duct sags or gets crushed, and insulation breaks down. A furnace or heat pump can run perfectly while a bedroom stays cold because its supply duct is blowing warm air into the attic. We check accessible duct connections during heating repairs and point out problems worth fixing. Dirty filters after smoky or windy periods are another frequent culprit, and they are the easiest fix of all.
When to repair and when to plan ahead
A single failed part on a system in reasonable condition is usually worth repairing. An aging furnace with a cracked heat exchanger or repeated breakdowns is a different story. If replacement comes up, we can walk through South Coast AQMD Rule 1111, which limits NOx emissions from gas furnaces sold and installed in the region and has been amended toward zero-emission requirements, and we confirm rebate options with the utility serving your address before discussing them.
Our heating repair technicians also cover San Fernando, Los Angeles, West Hollywood, Beverly Hills and Culver City.
