Replacement A/C Hose lines don’t have to be from the Original Manufacturer !
In the past it was difficult to find a supplier capable of doing AC hose repairs but with today’s wide selection of high quality fittings and hose, your replacement could be right here at ATC. The Air Conditioning System provides the desired cabin temperatures to ensure operator comfort. The AC hose is used to effectively transfer both liquid and gas between the components and should be inspected for leaks and repaired or replaced ASAP, to ensure the system continues to performance as expected.
Today many hose sets come with metal tube sections, some of which we offer. If no suitable fitting is available, using hose to replicate the metal tube is the next best thing.
Our experience suggests using Aeroquip hose and E-Z Clip may hold an advantage over crimp fittings for replacing metal tubes. Aeroquip EZ Clip & Hose fitting are a simple option for making or repairing Air Conditioning hose lines on heavy duty trucks, agricultural, construction and other industrial applications. No hydraulic equipment is needed, rather a simple, easy to use Crimping pliers enables quick and easy Ac Hose repairs in the field.
Each Aeroquip fitting comes with 2 Clips which slide over the hose and a Cage which locks into the fitting, goes through the cages and is secured with crimper pliers.
This example shows an OE Hose at the top and using 4 Aeroquip fittings and hose, we can quickly provide a quality solution for your application.
The reduced diameter hose enables tighter turns but not right angles, without concern for “kinks” which would compromise the hose and AC system.Call ATC at 800-295-4156 for all your mobile heavy duty HVAC parts, supplies and solutions – Burlington, Mississauga and Montreal.
AC Hose Repair using Aeroquip EZ Clip Fittings and Hose, is a quick solution for quick turn around needs and mobile technicians. Providing even greater flexibility, when the E-Z Clip fitting is lubricated with a slight amount of refrigerant oil, before it’s inserted into the hose, the direction/index of the fitting can be changed by rotating the fitting in the hose. Once the refrigerant oil used has dried (1-2 hours) the fitting can no longer be turned or re-indexed.
When it comes to air conditioning a good preventative maintenance program will increase operating time and save money by identifying concerns before they become problems. Once the hot weather arrives, implementing planned maintenance allows you to schedule repairs versus reacting to sudden unexpected issues. A/C filters, coils, and fins require regular maintenance to ensure optimum performance and neglecting necessary maintenance ensures a steady decline in performance and increases energy use.
Clogged, dirty filters restrict airflow and reduce a system’s efficiency. When airflow is restricted, the air that by bypasses the filter will carry dirt directly into the evaporator coil and reduce the coils heat absorbing abilities. To ensure efficiency routinely clean or replace filters.
The condenser and evaporator coils collect dirt over time but a clean filter helps to keep the evaporator performing. Debris reduces air flow, insulates the coil and reduces it’s ability to absorb heat. Being exposed to the elements, you can easily see dirt collecting on the fins. Cleaning the coil fins and removing any debris around the coil will ensure optimal performance.
The aluminum fins on evaporator and condenser coils are easily bent and can block airflow through the coil. Air conditioning wholesalers sell a tool called a “fin comb” that will comb these fins back into nearly original condition.Remember to always use caution when performing preventative system maintenance, as ambient conditions (heat load) will increase refrigerant hose temperatures and don’t forget having the right quality parts on hand makes all the difference.

Tech Tips From RedDot – Heavy-duty A/C components rarely fail. In fact, the system fails the components because of contaminated refrigerant oil and general lack of preventive maintenance.
One of the best ways to improve uptime and reduce maintenance costs for the customer is to promote a basic visual check of major A/C components, hose connections, and fittings at regular intervals, like with every engine-oil change. This inspection routine has another benefit: it can generate business for your parts and service department.
Many A/C components are consumable items. It’s more cost-effective to replace them than to repair them. So preventive maintenance is an opportunity to sell a range of OEM-quality all-makes replacement parts for the air conditioner. Here are some examples:
1. RECEIVER DRIERS
The receiver-drier’s moisture indicator provides a quick visual cue about the refrigerant’s condition: a blue dot means the refrigerant is dry; pink, white, or grey indicates acid or moisture in the system. Checking the sight glass during an oil change or any scheduled maintenance procedure means the truck can receive necessary service while it’s there in the shop, before moisture and acid damage critical A/C components and lead to a failure on the road.
Dust, bugs, feathers, and other debris collect on the face of fins and tubes and act as a thermal barrier, making it hard for the condenser to shed heat. Condensers also fail because of vibration, which can cause hose connections to come loose and fatigue the condenser tubing adjacent to the fittings. Every 12 months, the condenser should be cleaned (taking special care not to bend or damage the fins) and the hose connections securely clamped.
3. COMPRESSOR/CLUTCH ASSEMBLY
The compressor provides the mechanical energy to circulate refrigerant and manipulate the pressure inside the system. It’s the heart of the A/C system, and the No. 1 HVAC maintenance expense item. Excessive noise and poor cooling performance are the two most obvious symptoms that a compressor is failing. Replacing the compressor involves pulling down the system, which adds refrigerant recovery and recharge to the repair cost.
Next time you see, “A/C won’t blow cold air” on a work order, note that the repair and downtime probably could have been avoided with a simple visual inspection of the truck’s air conditioning system. Any time you change the truck’s oil, check the A/C.
A relatively new feature in the heavy duty industry, the cabin air filter is often overlooked in regular vehicle maintenance. That’s unfortunate because the cabin air filter is just as important to the passengers as the engine air filter is to the vehicle and a likely cause of “A/C Not Blowing Cold“. A cabin filter processes the air that enters the passenger compartment via the vehicle’s heating and air conditioning system, increasing passenger comfort by trapping particulates, pollen, and other irritants.
For people with allergies and other sensitivities to airborne agents, the cabin filter represents a significant advance. Replacing the cabin air filter at the recommended interval, or sooner especially in areas of high particulate, allows the A/C system to run at optimal efficiency and passengers to breathe cleaner, fresher air, which makes any journey more enjoyable – Courtesy of Denso Corporation
