When outdoor temperatures drop, you need your heater to function properly. A furnace operating at its peak will make your home feel comfortable and provide your loved ones with a warm indoor reprieve from the cold outdoor air. The simplest way to ensure your heating system works when you need it most is to schedule HVAC maintenance in preparation for high-use seasons. Despite your best efforts, if your heating system leaves you in the cold, Spoor's Heating & Air Conditioning is your first call for heating repair to restore your indoor comfort!

In the following, our heating and air company lists the four most common reasons for no heating from your system and explains what you should do next. Contact us today for more information and to schedule heater services you can count on!

Most Common Reasons For No Heating

Lack Of Maintenance

The most common reason a heater won't provide warm air or function as intended is a lack of professional maintenance to the system. If you fail to schedule bi-annual planned HVAC maintenance, then it's likely your system will experience unexpected problems and breakdowns. Dirty blower motors can lead to equipment failure and dirty air filters restrict airflow and may amplify existing issues with the ductwork. Additionally, a dirty flame sensor prevents the system from lighting the burners and dirty burners can impede the furnace's ability to operate well, if at all. The solution? Schedule routine maintenance with an HVAC technician! These routine inspections can help your heating system run both more efficiently and reliably and prevent you from dealing with the inconvenience and discomfort of a non-functioning furnace.

Thermostat Problems

If your thermostat uses batteries to operate, try replacing them with fresh ones. Though this may seem like a simple fix, you'd be surprised at the number of times old batteries account for indoor heating issues! Additionally be sure to check that your thermostat is set to the "heat" or "automatic" function, as this is required for the heating system to start producing hot air. In rare cases, smart thermostats can malfunction and require a quick rebooting of the system. The easiest way to go about this is to remove them from the wall, then reattach them to complete a manual reset. Your smart thermostat may, alternatively, have a "reset" button, in which case you should use this to reboot the system. If your thermostat is beyond repair, then it's time to call your HVAC company for prompt service! We will inspect your system and thermostat and recommend the best courses of action for getting your indoor heating system working properly!

Low Refrigerant Levels

Another common heating system issue faced by many Auburn homeowners during the cold season is low refrigerant levels. It is possible for refrigerant levels to drop too low and, when this happens, the heat strips might activate more frequently than you'd like them to (resulting in high utility bills and wasted energy). If you recognize that your heat strips activate more frequently than usual, then it may be necessary to increase the charge of your system's refrigerant. When the level is too low for an extended period of time, the compressor can overheat and fail completely. While you may be able to recharge the refrigerant and fix any leaks, your compressor may require replacement or the system may need to be replaced altogether, depending on the system's issues and state. In any case, our technicians are happy to help!

A Dead Blower Capacitor

Another common cause of heating-system failure results from a dead blower capacitor. Your heating system's blower capacitor looks similar to a large-size battery. In a properly functioning system, the blower capacitor activates the furnace when the thermostat is set to heat at a specific number, resulting in the thermostat communicating with the capacitor to turn on. Each capacitor has a tolerance level and, if the tolerance is below the normal level, your blower may not achieve the proper revolutions per minute, or RPM. In some situations, the capacitor fails to start the blower. In other cases, a dying or dead capacitor creates a blower malfunction, In both cases, the system requires professional repair. Due to the fact that capacitor failure is a common occurrence with heaters, our team always checks the tolerance of capacitors during routine inspections and service calls. Should they be near the end of their functional lifespan, you will let you know it's time to replace them!
