Winters in the San Dimas area may be mild when compared to other locales, but they can still be uncomfortably cold. In fact, winter nights can be very difficult to deal with unless the home has a properly functioning heating system. There are various devices used for home heating with the most common one being central heating, also known as a forced air system or furnace. One reason for this is that the furnace is also part of an HVAC (heating, ventilation and air conditioning) system, which is a standard appliance in many homes. Commonly used systems such as this tend to be reliable, but they still require the occasional Residential Heating Repair in San Dimas CA. For instance, the temperature sensing switch could fail and prevent the blower from starting.
Heating failures often depend on the type of appliance being used. Units that use electrical resistance can fail when the heating element wears out. Models that burn natural gas or propane can suffer from unexpected issues such as a loss of fuel control or a fault with the ignition system. Older gas furnaces use a burning flame as a pilot light while many modern systems employ electronic devices such as piezoelectric systems to ignite the flame. Unfortunately, electronic systems fail and force the need for emergency Residential Heating Repair in San Dimas CA.
Another area where the gas furnace can have problems is the exhaust. Gas burning appliances require proper airflow so that oxygen enters the combustion chamber. Unfortunately, the waste from the burning fuel can eventually clog up the exhaust pipes. This causes the flue to operate improperly and allows back-pressure to build up in the combustion chamber. The result is lower oxygen levels in the air and a poor flame. In fact, the problem may even be visible because the flame will be small. However, a completely blocked exhaust may prevent the fuel from ever igniting, which could cause even more problems.
The best way to avoid these concerns is to have the appliance serviced on an annual basis. Manufacturers recommend that the furnace is serviced in the late fall or early winter before it gets used. Learn more about heating maintenance and repair from the expert technicians at Cypressair.com.
