At D’Addario’s Auto Service, we specialize in keeping your vehicle’s climate control system running smoothly all year long. Whether you’re sweating through a hot East Hartford summer or freezing on a winter morning, our AC and heater repair services have you covered. From auto AC recharge to full car heater service, we help you stay comfortable, safe, and in control.

Stay Cool with Reliable Auto AC Repair

A malfunctioning air conditioner is one of the most common complaints drivers have in the warmer months. Your AC system doesn’t just cool the cabin—it also helps reduce humidity, which keeps you and your passengers more comfortable. When it fails, you’ll feel it right away.

Some common signs that your vehicle may need AC repair include:

• Warm or inconsistent airflow from the vents

• Weak air pressure even on high settings

• A musty or foul smell when the AC is on

• Strange clicking or buzzing noises from the dash

• Water leaking inside the cabin

If you’re noticing any of these symptoms, your system may need an auto AC recharge, a new compressor, or other component repairs. At D’Addario’s, we use top-tier diagnostic tools to pinpoint the issue quickly and get your air conditioner back to peak performance.

Our auto AC recharge service includes:

• Evacuating the old refrigerant

• Testing for leaks using vacuum or dye methods

• Refilling the system with manufacturer-recommended refrigerant

• Checking pressure and cooling output

• Inspecting belts, hoses, and compressor performance

We work with both R-134a and R-1234yf systems, so no matter what you drive, we’ve got the tools to handle it.

Warm Up with Expert Car Heater Service

When it comes to winter driving, a working heater is just as important as a working engine. Not only does it keep you warm—it also defrosts your windows and ensures visibility in cold, damp conditions. Our auto heat service is designed to diagnose and repair your car’s entire heating system.

You may need heater repair if you notice:

• Cold or no air coming from the heater vents

• Temperature fluctuations in the cabin

• A blower that only works on certain speeds

• Windows that fog up and won’t clear

• Coolant leaks inside the vehicle

Most car heater service issues stem from the heater core, thermostat, or blower motor. Our technicians will run a full system check, inspecting:

• Coolant levels and condition

• Thermostat operation

• Heater core flow and blockages

• Cabin air filters

• Electrical components and blower speed controls

Once we identify the issue, we’ll explain your options and give you a straightforward estimate. No upsells. No pressure.

What Causes HVAC System Failures?

Your car’s HVAC system is complex, and issues can come from a variety of sources. Here are some common causes of AC and heater problems:

• Low refrigerant due to leaks

• Clogged or leaking heater core

• Failing compressor or condenser

• Broken thermostats or blower motors

• Electrical problems like faulty switches or blown fuses

• Blocked cabin air filters

• Faulty blend doors or actuators controlling hot/cold air flow

Because both your heating and cooling systems share components with your engine’s cooling system, one problem can affect the other. That’s why we always run a full-system diagnostic to catch all potential issues.

• Heater inspection: Annually in early fall

• Cabin air filter replacement: Every 15,000–20,000 miles

Keeping up with these services ensures your comfort and helps prevent unexpected breakdowns.
