Knowing the most common types of furnace repair saves you from costs and worries. Listed below are the 10 most common types of furnace repair so you can fix it yourself or understand the technician.
Dirty or Completely Clogged Filters
Dirty or completely clogged filters will decrease the efficiency of your furnace. Your system will work hard to push adequate air to heat your home. This can damage the fan motor’s limit switch if left unattended, leading to a costlier repair than normal. It is also a fire hazard.
Thermostat Inaccuracies
The thermostat is an essential component of your furnace, as it acts like the brain of the system. It tells your furnace the temperature you want to maintain in your home and how often to turn it on to keep that temperature. A malfunctioning thermostat will not be able to give the correct instructions to your furnace. Your system may still work, but not as it should be or what you expect.
Deterioration on Components
Some components of your furnace will deteriorate over time. These include bearings, belts, filters, switches, motors, pilots, fan blades, and burners. Make sure to check these parts regularly to make sure they are in good working condition.
Ignition Problems
Ignition problems will make your system unable to generate any heat even if the other parts are in good working condition. There are several kinds of ignition systems, such as electric-powered or electrical spark and gas-powered or hot surface systems. Seek the help of a licensed HVAC professional to check on this for safety reasons.
Recurrent Cycling Between On and Off Modes
Something is wrong with your furnace if it seems to be cycling rapidly instead of the usual cycle of running for a time and staying off for a time. Call an HVAC professional to check your unit. It could be a dirty filter or a malfunctioning thermostat to a fan motor.
Odd Noises or Grumbles
It is normal to hear some noise when your system is running because of the fan and the blower. However, peculiar, odd, and irregular noises like bangs, rumbles, squeaks, clangs, rattles are indications of potential problems. This could mean that your furnace may have swallowed outside fragments or been occupied by household pests. It could also mean that some components have loosened or detached.
Your System Refuses to Work or Keeps Resetting
A thermostat issue could make your system to reset continually. It could also mean that there is a trip in the source of power. An interruption of gas power to the furnace can lead to a non-functioning system. It could also be caused by a problem with the gas pipe valve or the flame sensor.
Higher Electric Bills Even if Your Furnace is Not Working
A furnace repair is imminent if your electric bills are higher than usual, even or especially if your system does not heat your home adequately. High-energy consumption can indicate a dirty, underpowered, or damaged furnace.
Neglected Regular Maintenance
Regular maintenance is important to keep your system in perfect working mode. Timely replacement of certain components, lubrication of certain kinds of motors, tightening of screws and bolts, removing debris, and changing filters are a few vital maintenance tasks that can make your system healthy.
