Most homeowners know that they rely on their furnaces to keep their homes comfortably warm, even in the dead of winter. Few pay any attention to them, though. Unless something goes wrong, that is.
Unless they have plenty of HVAC experience, most modern homeowners don’t have the training, tools, and experience to diagnose and repair furnace problems by themselves. That doesn’t mean there’s nothing they can do to help prevent unnecessary breakdowns. Read on to find out about furnaces, how they work, and how to spot signs of trouble that may indicate it’s time to call for Furnace Repair in Boise, Idaho.
Most furnaces are fueled by either natural gas or propane. They ignite the fuel in a burner, which allows the flames to heat up a heat exchanger. The heat exchanger transfers heat to the incoming air, which is then blown into the home’s ductwork and distributed throughout the house. As the warm air fills the home, it causes the cooler, heavier air to be drawn back into the furnace through the system’s return ducts.
Sounds simple, right? In reality, modern furnaces require many components to accomplish this seemingly simple task.
To work efficiently, each of the furnace’s components needs to be kept in good working condition. Over time, the components wear out. This leads to system failures.
Most serious furnace problems don’t just happen out of the blue. They occur due to neglect. Homeowners can prevent many problems by scheduling annual inspections and maintenance visits, but even a highly trained professional won’t be able to prevent every possible malfunction.
Don’t wait until the furnace stops working completely to call for repairs. Instead, keep an eye out for these common problems:
Every furnace has air filters. These filters must be changed regularly to prevent the buildup of dirt and dust, which makes it more difficult for the unit to work efficiently. Failing to change the filters on time can raise monthly bills, cause unnecessary wear and tear, reduce the furnace’s expected lifespan, and increase the chances of an unexpected breakdown.
The furnace’s blower is responsible for moving hot air away from the heat exchanger and into the home’s ductwork. A slipped or frayed blower belt can cause it to malfunction. The most common sign off a slipped belt is a high-pitched squeal coming from the furnace itself.
Some furnaces feature pilot lights, while others use electronic ignitions. If either of these components malfunctions, it can cause a reduction in heat. Thankfully, ignition and pilot control problems are relatively easy and inexpensive to fix.
Not all problems with inadequate heating are caused by faulty pilot controls or ignitions. Sometimes, the problem lies in the thermostat. Technicians typically recalibrate their clients’ thermostats at annual maintenance visits, so keeping on top of preventative maintenance is the best way to prevent this problem.
There are several underlying problems that can cause furnaces to over-cycle. They include clogged filters, improper airflow, and thermostat malfunctions. Call a technician for a more accurate diagnosis.
A furnace’s limit switch is what tells the blower when to turn on and off. When it breaks, the furnace may just continually produce air, whether or not the heat is on. A technician can replace the faulty limit switch and restore normal functionality.
Without a functioning heat exchanger, even the most efficient furnace won’t be able to work as intended. Unfortunately, fixing a cracked heat exchanger is a relatively costly repair. It’s also a repair that can be avoided by sticking to a regular preventative maintenance schedule.
If they pay attention to their furnaces’ early warning signs, homeowners should know when they need repairs. It’s typically cheaper to fix small problems as they come up rather than wait until minor issues cause a catastrophic failure. It’s also much more pleasant to tackle problems in advance than it is to wait until the dead of winter when the household’s need for functional climate control is at its highest.
