Your furnace hasn't heated your home in months, but it hasn't been completely idle. In many DFW homes, the furnace blower runs all summer to circulate cool air. By fall, the blower and filter have seen plenty of use, while the burners and ignition system haven't fired up since winter.
At CityLine Air Conditioning, we help homeowners catch furnace problems before the first freezing night exposes them. Our fall tune-ups check the ignition system, airflow, and safety controls to make sure everything is working as it should. It's a good way to get ahead of DFW's unpredictable winter weather.
Your furnace doesn't have to stop working completely to give you a reason to schedule maintenance. Sometimes the clues are small, and you only notice them once the weather turns cold. Here are five things worth paying attention to:
It's been over a year since the last tune-up.
Even if the furnace ran fine last winter, that doesn't mean everything is still in good shape. An annual inspection helps catch wear, dirty components, and potential safety concerns before heating season.
The blower sounds louder than it used to.
A new rattle, hum, or squeal could mean a loose component or trouble with the blower motor. It's worth checking before those sounds become bigger problems.
You hear a bang when the burners ignite.
A loud bang at startup isn't something to ignore. Delayed ignition is one possible cause, and it can be dangerous. Have a technician inspect the furnace before using it again.
Some rooms took forever to warm up last winter.
If you kept turning up the thermostat but certain rooms stayed chilly, restricted airflow or furnace performance issues could be involved. A tune-up can help identify what's holding the system back.
You've recently moved into the house.
If you don't know when the furnace was last serviced, don't wait until something goes wrong. A maintenance visit gives you a clearer picture of its condition and what may need attention.
Furnace not turning on at all? That's a repair issue rather than routine maintenance. Our furnace repair service is the better place to start. If you're weighing a major repair against a new system, explore furnace installation and replacement. And if you'd prefer to make maintenance a regular habit, our Healthy Air Conditioner Club includes seasonal heating and cooling visits.
Keeping your furnace in good shape shouldn't come with surprise charges. We'll explain the cost of your maintenance visit before scheduling, so you know what to expect.
If you'd rather have seasonal maintenance taken care of, our Healthy Air Conditioner Club costs $189 annually for your first system. That includes two visits: a cooling tune-up in spring and a heating tune-up in fall, plus priority scheduling and other member benefits. Additional systems cost $100 each per year.

A little furnace care is easy to handle yourself. Changing a filter or checking an alarm takes only a few minutes. But once the job involves gas connections, electrical components, or opening the furnace cabinet, it's time for a trained technician.
Here's what you can safely handle and what we'll take care of.
| Fall task | Who handles it | Why |
|---|---|---|
| Changing the filter | You | A clean filter helps maintain airflow and keeps the blower from working harder than necessary. |
| Testing the carbon monoxide alarm | You | Test it according to the manufacturer's instructions and replace batteries or the alarm when needed. |
| Clearing space around the furnace | You | Keep stored items and combustible materials away, following the furnace manufacturer's clearance requirements. |
| Cleaning the burners and flame sensor | Our technicians | These components need careful handling to maintain reliable ignition and safe operation. |
| Checking the vent pipe and gas connections | Our technicians | Blockages, damaged venting, and gas leaks require professional inspection and testing. |
| Testing the blower motor and wiring | Our technicians | Electrical components need proper testing equipment and safe procedures to identify potential faults. |
Fall sits between our busy summer and the cold weeks, so tune-up dates are easier to get than in July or January. Club members hear from our office team in October, and anyone else can call and pick a date that suits them.
Your technician shows you a photo of the worn part and tells you its price in writing before touching it. If the van carries the part, it can be replaced on the same visit, and club members get 15% off the repair.
Your furnace doesn't have to be one we installed. Our technicians service major brands, including Carrier, Trane, Lennox, Goodman, and Amana. Whether your equipment is relatively new or has been heating your home for years, we're familiar with the systems we inspect.
If your furnace is in the attic, make sure the pull-down stairs are clear and nothing is stacked around the unit. Your technician needs room to open its panels.
Note your filter's size and keep a new one ready. Club members who leave a filter out for the visit get it installed while the technician is there.
The visit begins at the thermostat before your technician goes up to the furnace. Make sure its screen works and its batteries are fresh.
Findings go on an iPad with photos, and your technician goes over them with you before leaving. You'll know the furnace's condition and anything worth planning for.

There's something satisfying about switching on the heat and knowing the furnace has already been checked. Our technicians handle the inspection, maintenance, and performance checks, so you're not left wondering whether everything will work when the temperatures drop.
You don't need to wait for a cold front to book maintenance. A technician can run the furnace through a heating cycle, check its operation, and identify anything that deserves attention before regular winter use.
Maybe it's an older unit, or perhaps you're unsure whether it's getting close to replacement age. Bring up your concerns during the visit. We'll explain what we find and what it means for the seasons ahead.

A mild dusty smell during the first heating cycle can be normal after months of inactivity. It should disappear quickly. Persistent burning odors, smoke, or electrical smells need immediate attention.
Yes. Try running the heat on a mild day while you're home. You'll have time to notice unusual behavior and arrange service without waiting until the house becomes uncomfortable.
Yes. New equipment still needs periodic inspection and care. Regular maintenance helps identify installation-related issues, maintain proper operation, and document service history, which may matter under your manufacturer's warranty terms.
High-efficiency condensing furnaces produce water as they extract heat from combustion gases. That water should drain away properly. Pooling water or drainage problems warrant an inspection to identify the cause.
It can, particularly when dirty components or airflow restrictions affect performance. Maintenance helps the furnace operate as intended, although actual savings depend on equipment condition, thermostat settings, and usage.
