When Do I Start Preventative Maintenance for My Heater?
As Alabama’s long summer finally lets go, your heater is about to clock back in. The best time to schedule preventative maintenance is Early Oct. thru December so your system is tuned up before the first cold snap hits Birmingham, Hoover, Leeds, Trussville, Mountain Brook, Moody, and nearby communities.
Tri-Counties Heating & Air keeps local homes comfortable with reliable tune-ups, repairs, and replacements. Here’s when to book, what’s included, and how a simple visit can save headaches and money all winter.

System
When to schedule
How often
Why it matters
Gas or Electric Furnace
Early Oct. thru December
Once per year

Heat Pump
Early Oct. thru December and Mar/Apr
Twice per year

Packaged Unit
Early Oct. thru December
Once per year
Heavy seasonal load deserves a reset before winter
Signs You Should Book Sooner
You just moved, finished renovations, or skipped last year’s tune-up
Burning or dusty smell that doesn’t clear after 10–15 minutes of first heat
Odd noises, short cycling, or rising utility bills
System is 10+ years old or needed repairs last winter
If you ever smell gas or something electrical burning, shut the system off and call right away.
What Tri-Counties’ Heater Maintenance Includes
A professional tune-up goes far beyond changing a filter. Our technicians typically:
Inspect heat exchanger and burners; clean and verify proper ignition
Check flue venting and confirm there are no carbon monoxide risks
Tighten electrical connections and test safety controls
Calibrate the thermostat and verify temperature rise is within spec
Check blower motor and confirm healthy airflow at registers
Replace or clean the air filter
Evaluate duct leakage and static pressure for efficiency
Run a full heat-cycle performance and safety check
Beat the rush. The first cold front fills schedules. Early tune-ups get faster appointments.
Lower bills. Clean burners, correct airflow, and tighter ducts help your system use less energy.
Fewer breakdowns. Small fixes now prevent big mid-season repairs.
Safety first. Proper combustion and ventilation protect your home.
Quick DIY Checks You Can Do Today
Swap the air filter. If it looks like felt, it’s overdue.
Clear supply and return vents of rugs and furniture.
Set the thermostat to Heat and let it run for 10–15 minutes to test.
Check your carbon monoxide detector and replace batteries if needed.
