FAQs About Furnace Services
How much does it cost to service a furnace?
Furnace maintenance is one of the most affordable heating services available. Exact costs will depend on what kind of furnace you have, but you can usually get the best price if you sign up for a maintenance plan.
How often should you service your furnace?
Your furnace should be serviced a minimum of once per year, but it’s better to have it serviced in both the spring and the fall.
What does a furnace service include?
During your maintenance service, your technician will:
- Check the vent system and air intake grilles and remove blockages

How do you service a furnace?
The most important step homeowners can take is replacing or cleaning their furnace filters every two to three months to keep airflow strong and maintain efficiency. Beyond that, a complete furnace service should only be performed by a trained HVAC professional. During a service visit, the technician will inspect critical components like the heat exchanger, blower motor, burners, and safety controls. They’ll also clean the system, check for gas or carbon monoxide leaks, and ensure everything is operating safely and efficiently. Professional servicing not only protects your family’s safety but also helps extend the life of your furnace.
How long does a furnace cleaning take?
A typical furnace maintenance appointment lasts between one and two hours, depending on the type of system you have and its condition. If your furnace requires deeper cleaning, minor repairs, or adjustments, the visit may take a bit longer. Regular maintenance ensures your furnace runs smoothly through the heating season, helps prevent breakdowns, and improves energy efficiency.
How Much Does Furnace Service Cost?
The cost of furnace service can vary depending on your system’s age, condition, and the type of service needed. On average, a standard furnace tune-up costs between $100 and $300. If repairs are required, such as replacing parts or fixing safety issues, costs may be higher. At AIS Heating & Air Conditioning, we provide upfront pricing and financing options so you’ll always know what to expect before work begins.
How Often Should a Furnace Be Serviced?
For optimal performance and safety, your furnace should be professionally serviced at least once a year, ideally in the fall before the heating season begins. Annual service helps catch small issues before they become major problems, ensures your system is running efficiently, and can even help maintain your manufacturer’s warranty.
