Furnace Repair FAQ
What is the most common problem with furnaces?
While furnaces are designed to withstand years of use, it is not uncommon for furnace parts to experience wear and tear that can lead to costly repairs or furnace replacement. Some of the most common problems that require furnace repair include thermostat malfunctions, pilot light failures, and clogged filters. An old air filter is an especially overlooked issue, as it can be easy to neglect swapping it out every few months. However, filters act as a home air purification system and ensure ideal indoor air quality for your home. In any case, if you are not receiving proper furnace repair services, your furnace unit may end up failing when it is needed the most. Regular furnace repair and maintenance to address common furnace problems can help ensure that your heating system will be working properly for its entire lifespan. Call our furnace service experts at Radiant Plumbing & Air Conditioning today for a free estimate on your next furnace maintenance project.
What is the most expensive part to fix on a furnace?
HVAC systems are complex pieces of machinery comprised of numerous components. Some of these components can require costly repair. For instance, the blower motor, which is responsible for circulating heated air throughout your home, can cause homeowners trouble in the event it fails. Additionally, the furnace’s circuit board, which is essentially the brain of the furnace responsible for operating all its components, can be a costly headache. However, with annual furnace services like furnace repair and furnace maintenance from Radiant Plumbing & Air Conditioning, you can greatly reduce the chances that your furnace unit will face major issues.
What is the typical lifespan of a furnace?
The typical lifespan of a furnace depends on several factors, including the frequency of general maintenance as well as the amount of usage. Generally, a well-maintained furnace can last about 15 to 20 years. Though regular maintenance can improve efficiency and extend the life of the furnace, it’s important to remember that even with the best maintenance, it will eventually need to be replaced. This becomes especially apparent when you see your home’s heating costs rising. Don’t settle for a malfunctioning furnace, speak with our team of professional technicians today.
