We specialize in Air Conditioning — Heating and Cooling Cars, Trucks, Vans, SUVs, RVs, Motor Homes & Commercial Vehicles.
Auto Air Receivers / dryers
Auto Air Receiver driers are used only with expansion valve systems and serve two functions. They serve as a temporary storage container for excess refrigerant and excess air compressor oil commonly referred to as PAG oil. They also remove excess moisture from the emtire air conditioning system.
Auto Air Accumulators serve the same basic purpose as a receiver drier and are used with orifice tube automobile air conditioning systems.
New and Remanufactured Auto Air Compressors
The cost difference between new and rebuilt or remanufactured Automotive Air compressors is generally very little. Modern Auto Air uses new compressors whenever available unless you request us to do otherwise. In the long run this will save you time and money.
Auto Air Fan Clutches
An Auto Air fan clutch is a mechanical device or “clutch” that engages the cooling fan when temperatures in your car's engine compartment are elevated. This is critical at low speeds or in traffic when natural air flow through the airco unit's radiator and condenser is not great enough to remove the heat from the engine and AC system.
A faulty fan clutch in the air conditioning unit can cause overheating and damage to your engine as well, as high pressure and reduced performance of your air conditioning or “Auto AC” system. High pressure will usually always lead to damaged A/C components and loss of “Freon” R134A or R12.
Auto Air Conditioner Cooling Fans
Cooling fans for your auto air system can either be mechanically controlled by a fan clutch or powered by an electric motor - sometimes referred to as a radiator fan or condenser fan, depending on the application.
A faulty cooling fan can cause overheating and damage to your engine as well as high pressure and reduced performance of your air conditioning or “Auto AC” system. High pressure will almost always lead to damaged A/C components and loss of “Freon” R134A or R12.
Auto Air Hose Assemblies
Your automotive AC system contains several hoses and steel, or aluminum, lines that carry both high and low pressure refrigerant R134a or R12. Leaks in these components will cause loss of air conditioning refrigerant and poor performance. Modern Auto Air is equipped to manufacture hoses and hose assemblies on site.
Auto Air Fittings
We carry a full line of fittings for all of your vehicles heating, cooling and A/C systems
Auto Air Valves
Auto A/C, heating and cooling systems contain a variety of control valves including —
Service ports
Schrader valves
Heater control valves
vacuum valves
expansion valves and orifice tubes.
Auto Air Switches
Modern Auto Air carries and services a variety of switches including —
High pressure A/C cut off switches turn the air conditioning compressor off when pressures become too high. High pressure is usually a result of a bad cooling fan or blocked condenser or radiator
Low pressure AC cut off switches turn the AC compressor off when pressures are too low.
Low pressure is usually the result of low refrigerant levels or simply low demand for cooling such as in cooler weather. This is what causes the A/C compressor to cycle on and off. Cycling is normal under moderate ambient temperatures. Rapid cycling during hot weather is a sign of low refrigerant R134A / R12 levels.
Binary switches perform the function of both High and Low pressure switches.
Auto Air Relays
Car, Truck, Van and SUV air conditioning and heating systems (HVAC system) all contain various control relays that control the flow of electricity to components such as the AC compressor and blower motor. These relays are actuated by pressure switches and power control modules (PCM).
New and Remanufactured Auto Heater and Auto Air Conditioning Controls
Control units are either cable systems, vacuum systems or electrical. Many systems are a combination of all of these. Modern Auto Air is equipped to handle all types including the installation of custom systems for specialty, classic car and hot rods.
Auto Air Condensers
The condenser for your Auto Airco unit is also a heat exchanger. Its function is to give off heat and remove it from the system. A condenser looks much like your engine's radiator and usually sits in front of it, many times being cooled by the same radiator fan or condenser fan. The cooling fan is essential for low speed operation when there is limited natural air flow. These fans can be electric or manually controlled by a fan clutch.
Auto Air Evaporators
The Auto Air Evaporator, sometimes referred to as the evaporator core, is one of the two heat exchangers in an A/C system. The evaporator is usually located inside the vehicle, often deeply hidden under the dash. Refrigerant (years ago referred to as Freon) enters the evaporator in the form of a low pressure liquid and is metered through a device called an expansion valve or orifice tube.
The evaporator is the part of the system that gets “cold” air passes through it and into the cabin through the vents in your dash. Systems prior to 1993 used Freon or R-12 from 1993 to date R-134A refrigerant is used. We replace all types on all cars, trucks, vans and SUVs
Auto Air Heater Cores
If your car, truck, van or SUV is not heating properly or generating enough heat, your heater core could be at fault. Blockage can often be removed improving hot water flow to restore performance.
Auto Air Heater Cores also may develop leaks and leak anti freeze or coolant into the passenger compartment, usually showing up on the passenger floor.
Auto Air Blower Motors
Auto Air Blower motors move (or blow) air from outside or recirculate air from inside the vehicle through the evaporator / heater core case to cool, heat or defrost. Non-operating blower motors or blowers may be the result of other controls or relays and wiring. Have your system check by a qualified technician before replacing an inoperative blower motor.
Auto Air Engine Cooling Fan Motors
Cooling fans can either be mechanically controlled by a fan clutch or powered by an electric motor sometimes referred to as a radiator fan or condenser fan depending on the application. A faulty cooling fan or motor can cause overheating and damage to your engine as well as high pressure and reduced performance of your air conditioning or “AC” system. High pressure will usually always lead to damaged
A/C components and loss of “Freon” R134A or R12.
R134a Retrofit Components For Auto Air Units
In 1993 the EPA mandated the change from R12 refrigerant to R134A. Modern Auto Air has done thousands of conversions on these older systems. There may be no reason to replace all of the A/C components. Stop by for a free estimate.
Automobile Airco - Air Flow Problems
Poor air flow will result in reduced cooling or heating in your vehicle. Many newer cars have cabin filters much like the filters in your home HVAC system. Poor air flow is also frequently caused by broken or malfunctioning blend doors and mode doors or their actuators. Malfunctioning mode doors will cause air flow to be out of the wrong location such as out the defrost instead of the air vents.
Auto Air Blend Doors
Auto Air Blend doors control or “blend” air flow from a combination of heated and cooled air to maintain a set cabin temperature. They are controlled by cable, electric or vacuum actuators. Located inside the HVAC case, difficulty in replacement ranges from simple to completely removing the dash and air box from the car.
Auto Air Mode Doors
Mode Doors control air flow to the correct “mode” ie: defrost, panel vents or floor vents
They are controlled by cable, electric or vacuum actuators. Located inside the HVAC case, difficulty in replacement ranges from simple to completely removing the dash and air box from the car.
Auto Air Actuators
Actuators are electric or vacuum operated motors used to control mode doors and blend doors
Temperature Control Units both Automatic and Manual Auto Air Units
Many of today’s vehicles have sophisticated automatic HVAC systems to control air flow and temperature settings automatically. These units use a combination of switches, relays, temperature sensors and computers (PCM or power control modules, BCM or body control modules) to adjust your heat and air conditioning
New Auto Air Conditioning Installations
No air conditioning system in your car? Modern Auto Air has installed hundreds of systems in vehicles without factory installed air conditioning.

Auto Air Water Pumps
Auto Air Water pumps are the heart of your cooling system and circulate coolant or “anti freeze” through you car's engine and radiator to remove engine heat. Without a properly operating cooling system your engine will rapidly overheat causing severe and sometime fatal damage. We service all makes and models.
Radiators For Autos with Air Conditioning Systems
The automotive radiator has changed little over the years other than construction materials. Years ago it was cost effective to repair or “re-core” radiators. With new plastic and aluminum construction
they are more efficient and transfer heat better than copper but usually cannot be repaired. Replacement is the best option for a damaged or leaky radiator.
Leaks are often caused by corrosion or excessive temperatures that crack the plastic components. High temperature is most often caused by lack of coolant, a bad cooling fan or fan clutch. Corrosion is your radiators biggest enemy.
Coolant or “Anti Freeze” not only keeps the water from freezing in cold weather but contains corrosion inhibiters to keep the system clean and operating at peak efficiency. Most manufactures recommend a radiator flush and coolant replacement every 3 years regardless of climate.
Auto Air Heater Cores
An Auto Air Heater Cores is much like a small radiator and removes heat from the engine coolant.
They are located inside the HVAC case and air flow is controlled by blend doors that control or blend heated or cooled air to maintain the cabin temperature you set.
Heater cores are also prone to leaks from corrosion and will benefit from a “radiator flush” or coolant replacement.
