For Los Angeles residence, the first chill of winter can be rather shocking. When it’s time to turn on the heater for the first time in months, you may experience some difficulties. Some customers have told us that their heater does not operate even when the thermostat is turned on. There are a variety of reasons why this might be the case but here are some common issues we have come across.

  1. A safety switch is standard on furnaces constructed after the 1990s. This safety switch is crucial to your HVAC system’s general health and safety. If the safety switch detects that gas is being fed into your furnace without igniting it, the system will be turned off. If your system becomes too hot or senses a carbon monoxide leak, it will shut down as well. No matter what setting your thermostat is on, if the safety switch is tripped, you won’t be able to turn on your HVAC system until it’s checked by a professional.
  2. In order for the evaporator coil to function properly, the hundreds of small air passageways need to be cleaned regularly.  Your system won’t be able to provide enough heat if these passageways become clogged. The reduced airflow will not only reduce heat, but it will also have an impact on your power expenses. To attain the temperature set on your thermostat, your HVAC system will have to run longer, consuming more gas or electricity.
  3. The most important thing you can do for your HVAC system other than scheduled maintenance is to inspect and change your air filter on a regular basis. Your furnace’s issues could be caused by only a dirty air filter. When a filter becomes clogged, it inhibits airflow and makes your system work harder than it needs to.
  4. The blower motor, like other components in your HVAC system, can wear down over time. Overheating and excessive moisture are two common causes of blower motor failure. When dust, dirt, and debris accumulate, the windings and bearings might overheat and burn out more quickly overtime.
