Having your furnace serviced generally costs between $70 and $200 for a standard one-time tune-up, with most homeowners paying around $100 to $150. Annual maintenance plans usually cost between $150 and $500, covering regular checkups and sometimes offering priority service.
You should have your furnace professionally serviced once a year. This annual check-up is best scheduled in the late summer or early fall, ensuring the unit is safe, energy-efficient, and ready to handle the winter months.
The $5,000 rule is a guideline to help homeowners decide whether to repair or replace their HVAC system. You multiply the age of your unit by the cost of the needed repair. If that number exceeds $5,000, replacing your HVAC system is often more cost-effective.
How Can I Maintain My Furnace Myself? 4 DIY Tips
Short cycling
This is one of the most common furnace problems, and it can stress important furnace components such as the blower motor, limit switch, or flame sensor. There are several potential causes of short cycling, including some that are related to your furnace's built-in safety systems.
The Average Furnace Lifespan
A well-maintained furnace can last at least 15 to 20 years, but completing annual maintenance and being diligent with furnace repairs can extend its life even longer.
The heat exchanger is often considered the most costly part of a furnace to repair or replace. It is a critical component that transfers heat from the combustion process to the air that circulates throughout your home. Over time, heat exchangers can crack due to the constant heating and cooling cycles they undergo.
5 Warning Signs It's Time for Furnace Replacement
Customer Reviews and Ratings
Homeowners routinely praise Bryant for its reliability, solid warranty coverage, and lasting performance. Positive reports often highlight reduced energy bills after upgrading to Evolution systems.
If it doesn't start at all, you can press the button one more time. But, if you press the reset button and your furnace goes on and turns off again, don't press the button again. Continuing to press the reset button can damage your system. Doing so will pump more oil into the furnace and worsen any existing issues.
However, with the passage of the new budget, homeowners now have until the end of 2025 to take advantage of the HVAC tax credits, which include: $2,000 for a qualified heat pump. $600 for a qualified air conditioner. $600 for a qualified gas furnace.
If you don't clean your furnace, dust and debris can accumulate, leading to reduced efficiency and increased energy bills. It may cause overheating, frequent cycling, or even complete breakdowns, resulting in costly repairs.
The best time to buy a furnace is during the off-season, specifically late spring (April-May) or early autumn (September-October), when HVAC companies are less busy and offer lower prices, rebates, or promotions. Purchasing in these shoulder seasons ensures faster installation times and better negotiating power compared to winter peak season.
Your furnace needs cleaning if you notice rising energy bills, uneven heating, strange smells, or a yellow flame. A dusty furnace struggles to circulate air and can trigger allergy symptoms. Ideally, furnaces should be professionally cleaned and tuned once a year to prevent breakdowns and maintain safe operation.
Electric furnaces are relatively simple compared to gas systems, but they are prone to a few specific electrical and mechanical failures. The most common issues range from simple maintenance oversights to faulty electrical components.
A professional furnace inspection (or tune-up) consists of a comprehensive safety, efficiency, and cleaning check by a licensed HVAC technician. It typically includes testing thermostat calibration, inspecting the heat exchanger for cracks, cleaning the burners, and verifying safety shut-offs.
Is yearly furnace maintenance necessary? It's recommended, as annual furnace maintenance can spot potentially dangerous issues early on. For example, a gas furnace inspection could reveal a cracked heat exchanger.
To reset your furnace, turn off the power at the main breaker or emergency switch and wait 30 seconds to 5 minutes before turning it back on. This brief wait allows the electrical components to fully power down and ensures the system's computer reboots properly.
To fix a furnace that is short cycling (turning on and off rapidly without completing a full heating cycle), first replace your clogged air filter, check that all room registers are open, and ensure the outdoor exhaust vent is clear of debris.
When choosing a furnace, the best brand depends on what you prioritize: reliability, high-end efficiency, or budget-friendly value. Based on industry consensus and consumer ratings, the top three furnace brands are Carrier, Trane, and Lennox.
Neither brand is definitively "better" overall, but they excel in different areas. Trane is superior for durability, heavy-duty build quality, and overall reliability. Bryant is better for budget-conscious buyers, offering premium Carrier-tier features—like excellent humidity and zoning controls—at a lower price point.
A Bryant furnace typically lasts between 15 and 20 years. With excellent care and annual tune-ups, they can sometimes stretch up to 25 years. However, several factors determine exactly how long yours will run.
Most furnace issues stem from a few common culprits. The easiest to check yourself are clogged air filters and thermostat errors, which usually cause the system to blow cold air, run inefficiently, or cycle on and off constantly. Other frequent problems include dirty flame sensors or failing blower motors.
No, a standard gas furnace will not work without electricity. Even though they use natural gas or propane for heat, they rely entirely on electricity to power the ignition, safety sensors, control board, and blower motor.
To get your furnace to kick on, first verify your thermostat is set to "Heat" and raised at least 5 degrees above room temperature. Next, check that the furnace power switch (usually resembling a standard light switch on or near the unit) is toggled "ON".
