Illinois doesn’t do mild. Between July humidity and January cold, your car’s climate system works hard — and when it quits, it usually quits at the worst time. Whether your A/C is blowing warm or your heater can’t keep up, our techs track down the cause and fix it, instead of just topping off the refrigerant and sending you on your way.
That distinction matters with A/C especially. If your system is low on refrigerant, it’s because it leaked out — refrigerant doesn’t get “used up.” A recharge alone buys you cold air for a while, but it’ll be warm again by next summer if the leak isn’t found and fixed. We test for leaks first so you’re not paying to recharge the same system twice.
Illinois summers can quickly turn uncomfortable without working air conditioning. Here are the most frequent A/C issues we diagnose and repair at our Belleville shop, along with typical causes:
Often caused by a failing blower motor, clogged cabin filter, or electrical issues.
Low refrigerant (a leak), a bad compressor, or an electrical/control issue.
A clogged cabin air filter or a failing blower motor — the cabin filter is a cheap, often-overlooked fix.
Common with bad blend door actuators or control module problems.
Mold or bacteria buildup in the evaporator core creates musty smells.
Leaks in hoses, seals, or the condenser lead to poor cooling performance.
Cold winters demand reliable heat. Keep an eye out for these heating system warning signs:
Leads to poor heat output and potential engine overheating.
Prevents proper coolant circulation, causing only cold air from vents.
Results in weak or no airflow through the vents.
Low coolant, a stuck thermostat, a heater core issue, or a blend door problem.
Indicates issues with the heater control valve or sensors.
Usually a blend door actuator.
If you notice any of these warning signs, do not wait—have your vehicle inspected by the team at Rowan Tire & Auto Service. We perform full A/C recharges, leak repairs, compressor replacements, heater core service, blower motor repairs, and complete system flushes.
Late spring, before the first real heat wave — same logic for heat in the fall. Getting ahead of it beats sitting in a waiting room in August with everyone else whose A/C just died. It’s a quick conversation next time you’re in.
Before summer, have your A/C system checked — hot humid weather stresses the system. In fall, inspect your heater and defroster before freezing temperatures arrive. Regular cabin filter changes help maintain airflow and reduce odors year-round.
A: We recommend an inspection every 2 years or if you notice performance issues. Annual checks are wise for vehicles over 5 years old.
A: Bacteria and mold often build up in the evaporator. We offer cleaning and treatments to eliminate odors.
A: Only if there’s no leak. We always test for leaks first to provide a lasting repair.
A: Yes — we provide complimentary visual and basic performance checks with honest advice.
A: Almost always a slow leak. The real fix is finding and sealing it, not recharging again.
A: Sometimes, yes — a clogged one kills airflow and it’s an inexpensive part. We check it before assuming something bigger.
A: Yes — cars, trucks, SUVs, and minivans, foreign and domestic.
