Signs Your Furnace is Overdue for Maintenance

Five signs your furnace has gone too long without a maintenance visit.

You cannot remember the last time a technician inspected your furnace

If it has been more than 12 months, it is overdue regardless of how the system appears to be running.

Your heating bills have increased slightly from year to year without a change in usage patterns

Gradual efficiency loss from accumulated debris and component wear is measurable on your gas bill before it is noticeable in system performance.

Your furnace takes longer to reach the set temperature than it used to

Short cycling is usually caused by an oversized system, a dirty filter restricting airflow, or a control board sending incorrect signals to the equipment.​

You notice dust or debris coming from your vents when the furnace starts

This is often a sign that the system has not been serviced in a long time and that the internal components and ductwork have accumulated buildup that is now being circulated through your home.

Your system produces a faint burning smell when it first starts for the season

A brief smell at the start of the heating season can be normal as dust burns off, but a persistent smell indicates a problem that should be inspected before the system is run regularly.

NATE- Certified Furnace Maintenance

Most furnace failures do not happen without warning. The signs are there — a slightly longer startup, a burner that hesitates, a blower motor that sounds different than last year — but they only mean something to a technician who is paying attention.

Annual furnace maintenance in Cincinnati gives your system the attention before a small developing problem becomes a cold house in January. Air Plus provides furnace maintenance and tune-ups for homeowners across Greater Cincinnati and Northern Kentucky that go well beyond a filter swap and a visual check. Our NATE-certified technicians inspect and clean every component that affects performance, efficiency, and safety — the heat exchanger, burners, ignitor, flame sensor, flue system, blower assembly, electrical connections, and combustion analysis.

Join Air Plus Perks​

The Air Plus Perks program is designed for homeowners who want this level of attention on a consistent schedule. Perks members receive two performance tune-ups per year, 24-hour priority service 365 days a year, 10% off all replacement parts, no trip charges, an energy-saving coil cleaning, and a 30-day labor warranty.

The average homeowner spends approximately $1,500 per year on heating and cooling. A 15 to 20 percent efficiency loss from deferred maintenance wastes $225 to $300 annually. Air Plus Perks pays for itself.

What a Furnace Tune-Up Includes

A standard furnace tune-up checks that the system is running. An Air Plus furnace tune-up checks that it is running safely, efficiently, and without any developing problems that will turn into a repair call later in the season. Here is what our NATE-certified technicians do on every maintenance visit.
01
Combustion Analysis
We measure the composition of your furnace’s exhaust gases, and unlike most HVAC companies, we’re one of the few that actually performs a full combustion analysis to verify how efficiently and safely your furnace is operating. It’s a level of diagnostic precision most homeowners never get anywhere else.
02
Heat Exchanger Inspection
We inspect the heat exchanger for cracks, corrosion, or deterioration A cracked heat exchanger is a primary source of carbon monoxide intrusion in residential heating systems and a safety issue that is not visible without a proper inspection.
03
Burner Cleaning and Inspection
We clean the burners and verify that they are firing correctly, that the flame pattern is appropriate, and that no blockages are restricting combustion airflow.
04
Ignitor and Flame Sensor Testing
We test the ignitor to confirm it is generating adequate heat for reliable lighting and clean the flame sensor to prevent nuisance shutdowns caused by carbon buildup.
05
Flue System Inspection
We inspect the flue pipe and venting system for blockages improper connections or corrosion that could allow combustion gases to back-draft into the living space.
09
Energy-Saving Coil Cleaning
Air Plus Perks members receive coil cleaning as part of their AC and cooling maintenance. The EPA has found that as little as one-tenth of a centimeter of buildup on a coil can reduce system efficiency by up to 21 percent.
08
Filter Inspection and Replacement Recommendation
We check your current filter condition and advise on replacement frequency based on your system type filter rating, and usage patterns.
07
Electrical Connections and Controls
We inspect all electrical connections for corrosion, tightening any that have loosened, and test the thermostat, limit switches, and safety controls for proper operation.
06
Blower Motor and Assembly Check
We inspect the blower motor, belt if applicable, and fan blades for wear, and measure amperage draw to confirm the motor is operating within its rated range.

Schedule your annual furnace tune-up before the heating season begins.

Air Plus Perks members receive two tune-ups per year — call (513) 769-0871 or fill out the form below to schedule yours. We recommend scheduling in September or October before demand peaks in November.

Why Cincinnati Homeowners
Choose Air Plus to Maintain Their Furnace

Annual maintenance is the single most cost-effective thing you can do to extend the life of your furnace. Here is how Air Plus approaches it.

The Air Plus Perks Program Is Built Around Maintenance

Most HVAC contractors offer a maintenance plan as a secondary service. Air Plus built the Perks program with maintenance at its center. Members receive two performance tune-ups per year, 24-hour priority service 365 days a year, 10% off all replacement parts, no trip charges, an energy-saving coil cleaning, and a 30-day labor warranty. It is designed for homeowners who want a consistent maintenance relationship, not a tune-up they have to remember to reschedule next year.

Our Tune-Ups Go Beyond the Standard Checklist

Air Plus furnace maintenance visits include a full combustion analysis, heat exchanger inspection, burner cleaning, ignitor and flame sensor testing, flue inspection, blower assembly check, and electrical connection inspection. Our technicians verify that components are performing correctly at the component level, which is how developing problems get caught before they cause a failure.

NATE-Certified Technicians on Every Maintenance Visit

Every Air Plus technician who performs a furnace maintenance visit holds NATE certification, the heating industry's most rigorous independent credential. A maintenance visit performed by a NATE-certified technician is not the same as one performed by a technician who completed a basic company training program.

Upfront Pricing With No Surprises

Your technician presents the cost of the maintenance visit before any work begins. No fees added after the fact, and no pressure to authorize additional repairs during the visit. If a developing problem is identified, they will explain what they found and give you a separate estimate. You decide whether to proceed on your timeline.

Frequently Asked Questions About Furnace Maintenance in Cincinnati

How much does a furnace tune-up cost in Cincinnati?

Air Plus furnace tune-up pricing starts at $129. Air Plus Perks members receive two tune-ups per year as part of their annual membership and save 10% on all replacement parts in addition to paying no trip charges on any service call. Call (513) 769-0871 for current pricing.

Air Plus recommends scheduling your annual furnace tune-up in September or October, before the Cincinnati heating season begins in earnest and before demand for HVAC service appointments peaks in November and December. Scheduling early in the fall ensures your system is inspected and prepared before the first sustained cold stretch of the season, and it gives you time to address any developing issues before they become urgent.
A furnace inspection typically involves a visual assessment of the system’s components to confirm they are present and appear to be in working condition. A furnace tune-up goes further by cleaning components that accumulate buildup, testing component performance against rated specifications, and verifying safety-critical systems, including the heat exchanger, combustion gases, and flue venting. Air Plus furnace maintenance visits are comprehensive tune-ups that include combustion analysis, heat exchanger inspection, burner cleaning, and full component testing, not just a visual walkthrough.

The Air Plus Perks program is Air Plus’ annual maintenance membership. Members receive two performance tune-ups per year, covering both the heating and cooling seasons, 24-hour priority service 365 days a year with no trip charges, 10% off all replacement parts, an energy-saving coil cleaning, and a 30-day labor warranty on all services. To enroll, ask your Air Plus technician during your next service call or tune-up, or call the office at (513) 769-0871 to get started.

Yes, in two specific ways. First, regular cleaning of components such as burners, flame sensors, and coils prevents the accumulation of debris that causes components to work harder and fail sooner than they otherwise would. Second, a thorough tune-up by a trained technician identifies developing problems, such as a marginal ignitor, a hairline crack in the heat exchanger, or a blower motor drawing more amperage than it should, before those problems cause a complete system failure. Not every failure is preventable, but the majority of mid-season furnace breakdowns Air Plus sees are connected to deferred maintenance that allowed a developing issue to reach the point of failure.
Yes. The efficiency losses from deferred maintenance are gradual and rarely noticeable in day-to-day system performance until they have accumulated significantly. A furnace that appears to be working fine may be operating at 15 to 20 percent below its rated efficiency due to dirty burners, a partially blocked flue, or accumulated debris on internal components. That efficiency loss shows up on your gas bill every month, and it accelerates component wear that will eventually produce a repair. Annual maintenance catches those conditions before they compound.
