Motor RPM and blade design are critical when it comes to airflow. Airflow and amp draw are validated to ensure Company assemblies meet the unique requirements of the cooling systems to which they are applied.

As the heart of the A/C system, compressors are also at the heart of success. In fact, 66% new manufactured compressor units are made in house at ISO9001/TS16949 certified facilities. Extensive investment in tooling has provided the opportunity to develop and maintain necessary fixtures, CMM Technology (Coordinate Measuring Machine), smart lock systems and modern testing and validation processes ensure a quality product that is second to none.

Engineering validation process simulates real world environment equivalent to 100,000 miles. Every compressor is 100% vacuum and leak tested and every manufactured lot is subjected to random selection for validation testing, performed under extreme conditions.

When ready to ship, every compressor is shrink-wrapped for secure packaging to prevent damage during shipping and handling. Four Seasons® is the only supplier to provide all necessary hardware, o-rings and sealing washers needed.

As a basic manufacturer, Four Seasons identifies flaws and deficiencies in O.E design and engineers solutions for high pattern failures. The O.E. vane style compressor has inherent design flaws that causes the internal components to break down and accumulate debris in the compressor cylinder. If scoring occurs, the rotary vanes may become stuck in their slots, leading to potential seizing, resulting in premature compressor failure. The Four Seasons® solution uses a variable displacement, durable, proven, piston wobble plate design, noted for reliability and longevity. In addition it is much less sensitive to liquid slugging.

As a basic manufacturer in blower motors, Unimotor® manufacturing facility has the ability to identify known flaws and engineer/manufacturer a solution. Extensive quality control inspections ensure all engineering and quality requirements are met to ensure a superior quality and cost-effective product. Commitment to continuous improvement shows with TS16949 and ISO 14001 certifications. Each unit is 100% tested for functional performance and operational noise, before ever going out the door.

As a basic manufacturer in hose assemblies, capabilities extend past just putting a part in a box. Through modern manufacturing and advanced production equipment. Each unit is 100% inspected to ensure bend pipe consistency is maintained through a highly precise CNC bending machine. Hose assemblies play an important role in A/C system performance by carrying refrigerant and lubrication from one component to another. Poor manufacturing could lead to restricted refrigerant and oil flow to the compressor, resulting in catastrophic system failure.

Hoses are located in rear vehicle, behind tires. Constantly exposed to elements that cause corrosion, leading to a/c fluid leaks. Four Seasons is the first one in the market with a quality replacement solution.

Hoses Are Made Up of a Series of Layers:

As the image shows, hoses are made of four layers: Outer protective cover, reinforcing layer, elastomeric layer and impermeable barrier layer. But something to keep in mind, as hose ages, materials lose elasticity. They are more prone to leak at crimps, also internal layers may disintegrate – Particles slough off and contaminate system.

• Hose Condition – Especially internal, should be inspected if system opened
• Metallic abrasive particles - can embed in barrier layer following compressor failure

Tensioner Pulley and Idler Pulley product lines are manufactured to meet or exceed the original manufactures requirements for both automotive and heavy duty applications.

Tensioner and Idler Pulleys are made from either thermoplastic or steel, depending upon the OEM application demands. The pulleys can be grooved, flat, or flanged and all pulleys meet or exceed the OEM requirements. A Sealed bearings help insure a long bearing life and an aluminum dust cover is used to help prevent the possibility of dirt and other contaminates from entering the bearing which can lead to a premature failure.

Expansion Valves

Four Seasons expansion devices are specifically calibrated to provide proper flow to the evaporator as well as restricting or modulating high pressure liquid causing a pressure drop to lower the refrigerant temperature. They also provide optimum cabin comfort for both the driver and passengers.

Features

• Block Valves are aluminum construction; all internal parts are designed OE specifications.
• Internally and Externally Equalized Valves are copper and brass construction

Four Seasons® brings you the latest technological developments in the design of automotive air conditioning condensers by car manufacturers, providing you with a quality product you have come to expect from company. Company offer every condenser style to match the style, fit, and function of the O.E. condenser which includes a wide range of car and light truck applications.

Why choose Four Seasons® Condensers?

• Four Seasons® condenser brackets are ribbed to increase strength and rigidity for mounting and component support.
• All Four Seasons® integral oil coolers are designed with rectangular tubes to precisely match the O.E. configuration in terms of form, fit and function.
• Condenser tubes should never be used in the oil cooler section, nor should oil cooler tubes be used in the condenser section.
• Condenser side members are “U” shaped to increase rigidity and protection against fin damage from excessive stress.

Micro and Mini - Tube A/C condensers cannot be flushed successfully, small tube passages that are designed to make the condenser more efficient. Latest technological developments in car and light-truck A/C systems include micro-extruded tubes and mini-micro-extruded tubes which CANNOT BE FLUSHED. Do not take a chance with flushing, always replace the condenser when a compressor fails. Replacement will take the guessing out of the installation job.

Condenser technology has evolved dramatically over the past 10-15 years. Designs have changed from a “tube and fin” design to a “micro” tube design which has shown to improve airflow efficiency. Four Seasons® employs the latest technology developments from the O.E., including micro and mini-micro-extruded tubes. These two tube configurations cannot be interchanged, therefore, company condensers accommodate the design to replace the O.E. unit without any guessing.

The purpose of the evaporator is to condition the air in the vehicle passenger compartment. As air is blown across the surface of the evaporator fins, cold refrigerant flowing through the evaporator will remove heat and cool the air. As the air cools, moisture will condense into water on the fins lowering the humidity. The water will collect some of the dust and pollen filtering the air. Evaporators are made of aluminum to resist corrosion and are pressure tested at the factory. Company evaporators also come with the necessary O-rings and gaskets for ease of installation.

When a blower motor resistor fails, it’s recommended to replace the connector. A blower motor resistor connector connects the HVAC control module and the blower motor resistor. The connection between the electrical terminals of the blower motor resistor and the wiring connector that powers the module may be incapable of conducting higher current levels for sustained periods of blower motor operation. In addition, moisture and other contaminants may enter the fresh air intake and corrode the terminals. If any of these were to occur, the blower motor resistor or wiring connector could overheat and burn.
