What We Do

Every A/C & Heating Service You Need

From a simple Freon recharge to a full compressor replacement — we handle it all in-house, with honest pricing and same-day diagnostics.

Specialists, Not Generalists

Most shops treat A/C and heating as an afterthought. We built our entire operation around it. Every technician, every tool, every diagnostic process is focused on one thing: your car's climate system. That focus means faster diagnosis, fewer comebacks, and repairs done right the first time.

01

Freon Recharge

Restore your cooling power.

Over time, refrigerant levels drop — even without a leak. A Freon recharge restores your system to factory charge levels so your A/C blows cold again. We use the correct refrigerant type for your vehicle (R-134a or R-1234yf) and verify system pressure before and after service.

  • Correct refrigerant type for your vehicle
  • Pressure test before and after
  • Includes basic system inspection
  • Most vehicles completed same day
02

Leak Detection

Find it before it gets worse.

A refrigerant leak won't fix itself — and recharging without finding the source is just throwing money away. We use UV dye injection and electronic leak detectors to pinpoint exactly where your system is losing refrigerant, whether it's a fitting, hose, condenser, or evaporator.

  • UV dye + electronic detection
  • Full system inspection
  • Written report of findings
  • Repair estimate provided same day
03

Compressor Replacement

The heart of your A/C system.

The compressor is the most critical — and expensive — component in your A/C system. When it fails, you lose cooling entirely. We replace failed compressors with quality OEM-equivalent parts, flush the system to remove debris, and replace the orifice tube or expansion valve to protect your new compressor.

  • OEM-equivalent compressor
  • System flush included
  • Orifice tube / expansion valve replaced
  • Warranty on parts and labor
04

Heater Core Repair

No heat? We'll fix that.

The heater core is a small radiator inside your dashboard that heats cabin air. When it fails, you get no heat — or worse, coolant leaking into your interior. We diagnose heater core failures, perform flushes when possible, and replace the core when necessary.

  • Coolant leak diagnosis
  • Heater core flush (when applicable)
  • Full heater core replacement
  • Coolant system refill and bleed
05

Component Replacement

Every part of the system, covered.

Beyond the compressor, your A/C and heating system includes condensers, evaporators, expansion valves, receiver-driers, and more. We diagnose and replace any failed component with quality parts, and always verify the full system after repair.

  • Condenser replacement
  • Evaporator replacement
  • Expansion valve / orifice tube
  • Receiver-drier and accumulator
06

Heating System Diagnostics

Find the root cause, not just the symptom.

Heating problems can stem from a failing thermostat, low coolant, a clogged heater core, a faulty blend door, or a broken control module. We run a full diagnostic — not just a visual check — to identify the actual cause before recommending any repair.

  • Full system scan
  • Coolant level and condition check
  • Thermostat and blend door inspection
  • Written diagnostic report
07

Electrical & Control Repairs

When the controls don't respond.

Modern climate systems are heavily electronic. Blend door actuators, HVAC control modules, blower motor resistors, and wiring faults can all cause A/C or heating failures that look like mechanical problems. We diagnose and repair the electrical side of your climate system correctly.

  • Blend door actuator replacement
  • HVAC control module diagnosis
  • Blower motor and resistor repair
  • Wiring fault diagnosis and repair

Not Sure What's Wrong?

Bring it in. We'll diagnose it the same day and give you a straight answer.
