Some, but not all, of the hardworking appliances inside your home raise energy bills as they start to wear out. If you are concerned with keeping your home’s energy costs low and you depend on the conveniences they offer, keep an eye on these vulnerable appliances:
Next to your HVAC system, the water heater uses the most energy, and if it isn’t energy efficient to start with, its consumption could be high. As water heaters age, mineral solids in the water solidify at the bottom of the tank and the appliance starts to lose its efficiency.
It’s also the one appliance that can do a lot more damage if it isn’t replaced as it starts to fail. A leaking or burst water heater will flood the area around it, and water damage isn’t cheap or easy to repair. If yours is over 12 years old, it’s time to think about replacing it.
The refrigerator is another appliance that runs 24/7 and it will lose efficiency over time. Since it pulls air from the surrounding area, its components are often covered with dust. The gaskets around the refrigerator and freezer doors can start to leak, a sure sign the refrigerator is driving up energy bills. While you can replace the gaskets, they are expensive, and often cost more than the appliance is worth.
Over time, microwave ovens do wear out. The magnetron inside them will lose power over time. Most microwaves also use a mica plate that diffuses the microwave energy that will deteriorate over time, especially if it’s dirty.
Like anything mechanical, HVAC equipment will wear out and as they do, energy costs rise. The lifetime of most systems ranges between 12 and 20 years. Although this appliance is the most expensive in most homes, replacing it increases comfort and lowers energy consumption.
It’s important to stay on top of the maintenance these appliances require to keep energy bills low and prolong their lifetimes. To learn more, contact Roth Home & Cooling, providing trusted HVAC services for Portland area homeowners.
