September in Branson can still feel like summer, so your furnace is probably the last thing on your mind. But this is actually one of the best times to make sure it works.
Finding out your furnace has a problem on a mild September morning is inconvenient. Finding out on the first freezing night of the year is a much bigger problem.
You don’t need to take anything apart or know much about HVAC equipment to give your furnace a basic test. A few simple checks can tell you whether it appears ready for another Ozarks winter or whether it is time to schedule heating repair before cold weather arrives.
Start With the Thermostat
Set your thermostat from cooling to heating and raise the temperature several degrees above the current room temperature.
Within a short time, you should hear the heating system begin its startup sequence. Depending on the type of system, there may be a brief delay before the blower starts moving warm air through the vents.
Give the system several minutes to get going. Don’t keep raising and lowering the thermostat if the furnace doesn’t respond immediately.
If nothing happens after several minutes, check that the thermostat has power and replace its batteries if necessary. If the thermostat appears normal but the furnace still won’t start, the problem may be inside the heating system.
Let the Furnace Run for a Full Cycle
Don’t turn the heat back off as soon as warm air reaches the vents.
Let the furnace run long enough to raise the room temperature to the thermostat setting. You want to see whether it can complete a normal heating cycle without shutting down unexpectedly.
Pay attention to what happens.
The furnace should start, produce steady heat, and eventually shut off after reaching the desired temperature. It should not repeatedly turn on and off every few minutes.
Frequent cycling or very short heating runs can indicate several problems, including restricted airflow, thermostat trouble, overheating, ignition issues, or other mechanical problems.
If the furnace is cycling on and off instead of completing a normal cycle, having it checked now can prevent a breakdown later.
Check the Air Coming From the Vents
Walk through the house while the furnace is running.
The air coming from the supply vents should feel warm, and there should be noticeable airflow in the rooms served by the system.
One room being slightly different from another does not necessarily mean the furnace is failing. However, very weak airflow throughout the house can point to a clogged filter, blower problem, ductwork restriction, or another issue.
Make sure furniture, rugs, boxes, or other items are not blocking your supply or return vents.
If airflow remains unusually weak, Knight can inspect both the heating equipment and your home’s ductwork to find the source of the problem.
Listen for Noises You Don’t Remember Hearing
A furnace isn’t silent. You will normally hear the system start, the blower run, and the ductwork expand slightly as it heats up.
What you don’t want to hear are loud or persistent noises that weren’t there before.
Banging, grinding, squealing, scraping, or repeated clicking can indicate a component that needs attention. A new noise is especially worth investigating if the furnace has been sitting unused for several months.
Don’t wait for an unusual sound to become dramatically worse. Mechanical problems rarely improve by themselves.
Pay Attention to Smells
It is fairly common to notice a dusty smell the first time you turn on the furnace after summer. Dust can settle inside the system during the cooling season and create an odor when the furnace first heats up.
A light dusty smell should normally fade as the system runs.
A strong electrical smell, melting-plastic odor, persistent burning smell, or gas odor is different. Turn the system off if something smells seriously wrong.
If you smell gas, leave the area and follow your gas utility’s emergency procedures rather than continuing to test the furnace.
Check the Furnace Filter
September is also a good time to look at your HVAC filter.
Hold it up to a light. If it is heavily covered with dirt and dust, replace it with the correct size and type for your system.
A clogged filter restricts airflow through the furnace. That can reduce comfort and force the equipment to work harder. In some cases, restricted airflow can cause the furnace to overheat and shut itself down.
Keeping the filter clean is one of the simplest things a homeowner can do between professional service visits.
Check Your Carbon Monoxide Detectors
If your home has a gas furnace or other fuel-burning equipment, make sure your carbon monoxide detectors are working before heating season begins.
Test each detector and replace batteries when needed. Also check the manufacturer’s replacement date for the detector itself.
A carbon monoxide alarm should never be ignored. If an alarm sounds, get everyone outside and follow local emergency guidance.
Don’t Remove Furnace Panels to “Test” More
A homeowner furnace check should stay simple.
There is no reason to remove access panels, bypass safety switches, adjust gas components, or attempt electrical testing just to see whether the furnace is ready for winter.
A furnace contains electrical components, moving parts, hot surfaces, and, in many systems, natural gas and combustion equipment.
If the basic test reveals something unusual, that’s where a professional inspection makes more sense.
What If Your Furnace Doesn’t Pass the Test?
September gives you an advantage: time.
If your furnace won’t start, blows cold air, cycles repeatedly, produces weak airflow, makes strange noises, or behaves differently than it did last winter, you can take care of the problem before everyone in Branson starts turning on their heat at the same time.
Knight Heating & Air Conditioning provides furnace and heating repair in Branson and throughout the Tri-Lakes area. Our technicians can diagnose ignition problems, airflow issues, thermostat problems, worn components, and other heating system failures.
If the furnace appears to be working properly but hasn’t been serviced recently, this is also a good time to schedule heating maintenance. A professional fall tune-up goes well beyond the simple checks a homeowner can perform.
Test It Now, Not on the First Freezing Night
You don’t have to wait until you actually need heat to find out whether your furnace works.
Pick a cooler morning, turn the thermostat to heat, and let the system complete a full cycle. Listen, look, and pay attention to anything that seems different from last winter.
If something doesn’t seem right, schedule heating service with Knight Heating & Air Conditioning while the weather is still comfortable. It’s much better to discover a furnace problem now than during the first cold night in the Ozarks.
