Furnace repair services — San Jose, CA

Several things could be causing your furnace to run but not produce heat. It might be a tripped breaker, a dirty air filter restricting airflow, or an issue with the pilot light or ignitor. Sometimes, it's a problem with the thermostat or a more complex mechanical failure within the unit itself. A qualified pro can pinpoint the exact cause.

While often discussed for AC units, the 'rule of thumb' suggests if a repair costs more than half the price of a new system, replacement might be more cost-effective. For furnaces, this means weighing the expense of a major repair against the investment in a new, more efficient unit. It's a financial consideration to discuss with the technician.

The cost of an average HVAC repair or service in San Jose varies significantly based on the complexity of the issue and the parts needed. Simple fixes like thermostat adjustments or filter replacements are less expensive than compressor or heat exchanger repairs. Always ask for a detailed quote before any work begins to understand the expected cost.

The '3-minute rule' in HVAC refers to waiting at least three minutes after shutting off your AC or furnace before turning it back on. This allows the system's internal components, particularly the compressor, to equalize pressure. Restarting too soon can damage these parts and lead to costly repairs.
