Common Auto A/C and Heater Problems

Your vehicle’s air conditioning and heating systems are both part of the HVAC (Heating, Ventilation, and Air Conditioning) system. When one part fails, it can affect the performance of the whole unit. Here are some of the most common issues we fix at our Union City shop:

• Low refrigerant levels from leaks or long-term use

• Clogged cabin air filters reducing airflow

• Failing compressors or blower motors

• Blocked heater cores that prevent warm air

• Faulty thermostats or sensors

• Leaks in hoses or seals

• Broken relays or fuses in climate control systems

Whether it’s hot air on a summer day or no heat during a winter drive, TL Auto Repair can pinpoint the issue and get you back to comfort fast.

Warning Signs You Need A/C or Heater Repair

If your car’s interior climate feels off, it may be time to have your system looked at. Pay attention to these signs:

• Air blows warm when the A/C is on

• Weak or no airflow from vents

• Musty or burning smells when using heat or A/C

• Cold air doesn’t warm up after a few minutes

• Loud noises when turning on the fan

• Foggy windows that don’t clear up

• Dashboard warning lights or error messages

These issues can worsen over time and affect your vehicle’s efficiency. Early repairs help prevent more costly damage.

Our Climate Control Repair Process

At TL Auto Repair, we use advanced diagnostic tools and proven methods to service your A/C and heating systems. Here’s what you can expect:

1. System Evaluation – We inspect your car’s A/C and heater components, including the compressor, blower motor, and cabin filter.

2. Leak Detection – We use dye and pressure tests to check for refrigerant or coolant leaks.

3. Component Testing – We test fans, relays, thermostats, and sensors to confirm they’re functioning properly.

4. Repairs or Replacements – Whether it’s a simple recharge or a more complex heater core replacement, we do the job right.

Every repair is done with attention to detail and clear communication. We keep you informed at every step.

Stay Comfortable Year-Round

While air conditioning is crucial during hot Union City summers, a working heater is just as important in the colder months or on early morning commutes. A broken heater not only makes for an uncomfortable ride—it can also impact visibility and safety by preventing proper defrosting of your windows.

Our heater repair services include:

• Heater core inspection and replacement

• Coolant level and condition check

• Thermostat testing and replacement

• Vent and airflow diagnostics

• Fan and blower motor testing

We help you stay warm when it matters and cool when you need it most.

FAQs About Car A/C and Heater Repair

Why is my car A/C blowing hot air?
Most often, this means your system is low on refrigerant or has a leak. It can also signal a failing compressor or electrical issue.

Why doesn’t my car heater work?
A broken heater could be due to a faulty thermostat, low coolant, or a clogged heater core. We’ll run tests to find the cause.

How often should I get my A/C or heater serviced?
Once a year is ideal. Regular inspections catch small problems before they turn into expensive repairs.
