What type of maintenance does a furnace need?
Routine furnace maintenance typically involves cleaning or replacing filters, inspecting the burner and flame sensor, and checking electrical connections. A technician may also clean blower components and inspect the heat exchanger for safety. An annual check-up helps ensure your system runs efficiently and can prevent future breakdowns.
What's the most common type of furnace failure?
The most common furnace failure is probably a dirty or malfunctioning ignition system. Issues with the igniter, pilot light, or flame sensor can prevent a furnace from turning on or staying running. These problems often develop from normal wear, dirt buildup, or lack of routine maintenance.
Other frequent issues include clogged filters, faulty thermostats, and worn-out blower components. A professional furnace service can help diagnose and correct these common problems.
What can raise the cost of getting a furnace serviced?
Several factors might impact the cost of your project, including:
Type of service: A full furnace replacement will generally cost much more than a routine tune-up or a minor repair.
Furnace model: Costs can vary depending on your furnace's type (gas, electric, or oil), its age, and its overall condition.
Parts and repairs needed: The price can increase based on the specific parts that need to be replaced, such as a new ignitor, blower motor, or heat exchanger.
Unit accessibility: If your furnace is in a hard-to-reach area like a tight crawlspace or attic, labor costs may be higher due to the extra time involved.
Timing of the service: Emergency or after-hours service calls typically come with a higher price tag than appointments scheduled during regular business hours.
What happens if you don't service your furnace?
Skipping furnace maintenance can lead to safety risks, higher energy bills, and unexpected breakdowns. Without regular maintenance, your furnace's parts may wear out unnoticed or its airflow can become restricted. This typically causes the furnace to work harder, increasing energy use and potentially shortening its lifespan. In gas furnaces, neglect can also raise the risk of potentially deadly carbon monoxide leaks.
Routine service by a furnace pro can help catch small issues early, reduce the chance of more costly repairs, and keep your system running safely.
How long does furnace servicing take?
It usually takes a few hours to a full day to service a furnace. A few things can affect this timeline, like:
The type of service: A simple repair or tune-up is generally much quicker than a full furnace replacement, which can take several hours.
Furnace accessibility: Working in a cramped crawl space or attic will often take longer than servicing a unit in an easily accessible basement.
Unexpected repairs: If the technician finds other issues, like damaged ductwork or wiring problems, the job can take more time.
Parts availability: The service may be delayed if a specific replacement part needs to be ordered.
System complexity: Newer, high-efficiency furnaces often have more intricate components, which may extend the time needed for service.
Remember: The timeline for your project may vary, so ask your pro to provide an estimate.
How often should a furnace be serviced?
It’s a good idea to have your furnace serviced at least once a year. Regular maintenance can help your system run more efficiently, which may lower your energy bills. An annual check-up also helps catch potential problems early, helping prevent costly breakdowns and ensure safe operation.
How do I choose the right pro to maintain my furnace?
These steps can help you choose the right furnace services for your needs:
Verify license and insurance: Look for a licensed HVAC contractor with general liability and workers' compensation insurance. Certifications like NATE (North American Technician Excellence) can also show a high level of expertise. Requirements vary by region.
Get several estimates: A proper estimate is generally a written quote that breaks down costs for labor, parts, and any permits. It should also outline the scope of work and a timeline.
Read reviews: Be wary of red flags like unresolved problems, poor communication, or upselling unnecessary services.
Find out about warranties: Ask if the technician offers a warranty on their labor and on the parts they use. Companies sometimes guarantee their workmanship for a specific period, such as one year.
Ask other questions, like: Do you have experience with my specific furnace brand and model? Is the service call fee applied to the final repair cost?
