Ohio summers are hot. Ohio winters are cold. When your AC stops cooling or your heater stops warming, you need it fixed fast — and fixed right. ER Autocare's ASE-Certified technicians diagnose and repair AC and heating systems at all four Columbus Ohio locations. Same-day service. Free loaner cars. 3-year / 36,000-mile warranty.
Your vehicle's heating and AC system does more than keep you comfortable. In Ohio winters, your heater also powers your defroster — the system that clears ice and fog from your windshield so you can see. A heater that blows cold air on a January morning in Columbus isn't just uncomfortable. It's a visibility hazard.
On the AC side, Columbus Ohio summers are genuinely demanding. The humidity, the heat, and the stop-and-go commuting that comes with living in a growing metro put sustained load on compressors, condensers, and refrigerant systems. A small leak that goes unfixed through the spring becomes a seized compressor by August — a significantly more expensive repair.
At ER Autocare, our ASE-Certified technicians diagnose AC and heating problems correctly — finding the root cause, not just the symptom. We check refrigerant pressure, compressor function, condenser and evaporator condition, thermostat operation, heater core flow, and blend door actuator performance. You get a full written estimate before we start and our 3-year / 36,000-mile warranty when we finish.
Over 14,400 satisfied customers across Columbus Ohio trust ER Autocare with their vehicle comfort — and that trust starts with a diagnosis done right. That's what Masters of Our Craft looks like, even when you're sweating in August or freezing in January.
Your vehicle's heating and cooling systems are connected — both rely on your engine and coolant circuit to function. Understanding how they work helps explain why regular maintenance prevents the failures that leave Columbus Ohio drivers stranded in extreme weather.
Your heating and AC system usually gives you clear warnings before a complete failure. Here's what to watch for — and what each symptom typically indicates. Any of these should prompt a visit to your nearest ER Autocare Columbus Ohio location.
| Sign | What It Typically Indicates |
|---|---|
| AC blows only slightly cooler than outside air | Low refrigerant from a leak, or a failing compressor |
| Air smells damp, musty, or mouldy from vents | Mould or bacterial buildup in the evaporator or cabin filter |
| Weak or no airflow from vents | Blocked vents, failing blower motor, or clogged cabin air filter |
| Heater blowing cold or cool air | Low coolant, stuck-open thermostat, or clogged heater core |
| Defrosting takes too long or doesn't clear | Weak heater output or failing blower |
| AC stops working when idling | Refrigerant leak, compressor fault, or electrical issue |
| Hot and cold air mixing incorrectly | Blend door actuator failure |
| Clicking or grinding from AC when turned on | Failing AC compressor clutch |
Every AC and heating inspection at ER Autocare Columbus Ohio covers the full system — not just the component that's obviously failing. Here's exactly what our technicians inspect when you bring your vehicle in.
From a refrigerant recharge to a full compressor replacement or heater core service, every ER Autocare Columbus Ohio location handles the complete range of climate control repairs. Written estimate before we start. Our 3-year / 36,000-mile warranty when we finish.
Full system inspection — refrigerant pressure, compressor clutch, condenser and evaporator condition, heater core flow, blend door function, and HVAC fault code scan. We find the actual cause, not just the symptom.
We recover, evacuate, and recharge to manufacturer specification. We always check for the leak that caused the low charge first — recharging a leaking system without finding the leak is a waste of your money.
A seized or failed compressor means no cooling. We replace with a quality unit, flush the system, install a new receiver drier, and fully recharge — completing the job properly, not halfway.
A leaking condenser or clogged evaporator kills AC cooling capacity. We pressure test both components and repair or replace as needed, followed by a full system recharge and output verification.
Cold air from your heater points to a thermostat stuck open, a clogged heater core, or low coolant. We diagnose the exact cause, flush and replace the heater core where needed, and restore proper cabin heating.
Blend door actuator failures cause incorrect temperatures, stuck airflow direction, and control panel issues. We diagnose the HVAC control system and replace failing actuators to restore proper climate operation.
Heating and AC systems can wear out over time with use. Hoses become clogged, refrigerant leaks slowly through fittings, and components like the compressor and heater core degrade from seasonal demand. In Columbus Ohio — where winters regularly reach single digits and summers push heat and humidity well past comfort levels — that seasonal stress is real.
Regular AC and heating inspections prevent these gradual losses from becoming complete failures. Catching a refrigerant leak in spring costs a fraction of what a seized compressor costs in July. Catching a weak heater core in September prevents a defroster failure in January. At ER Autocare, we include a heating and AC check as part of every multi-point inspection — so nothing sneaks up on you between seasons.
We recommend a full AC and heating system inspection at least once a year — ideally before summer or before Ohio winter arrives. All backed by our 3-year / 36,000-mile warranty, free loaner cars, and financing available for any repair that needs it.
We find leaks before recharging. Topping off a leaking system just delays the same problem. We fix the cause — so your AC stays cold after we're done.

Common signs include AC blowing air only slightly cooler than outside temperature, air that smells damp or musty from the vents, weak or no airflow, the AC stopping when your vehicle is idling, or the system not turning on at all. Any of these warrants a same-day inspection at your nearest ER Autocare Columbus Ohio location.
A heater blowing cold air is typically caused by low coolant levels, a faulty thermostat stuck open, a clogged or leaking heater core, or a blend door actuator failure. Our ASE-Certified technicians diagnose the exact cause and provide a written estimate before any work begins.
We recommend a full AC and heating system inspection at least once a year — ideally before summer or before Ohio winter arrives. Catching a refrigerant leak in spring costs a fraction of what a seized compressor costs in July. We include a heating and AC check in every multi-point inspection.
Warm air from a car AC is most commonly caused by low refrigerant from a leak, a failing or seized AC compressor, a clogged condenser, or a faulty expansion valve. At ER Autocare Columbus Ohio, we run a full AC diagnosis to find the root cause — not just recharge and send you home with the same leak still in the system.
