Tool kit for installation and maintenance of air conditioners

Equipment for installing split systems should be in the arsenal of the installer if he is engaged in this type of activity as a business. This is a good source of income, especially in the summer season. Installation of air conditioners continues in the form of installing industrial air cooling systems and repairing refrigeration units in shops and shopping centers - this equipment often breaks down there, because it works day and night. The type of activity is especially in demand in small cities. Equipment can be rented for the first time, but it is better to have your own set - it will cost less, and the price will pay off over time.

Air conditioning installation tools

The quality of work will directly depend on:

• the experience of the installation team, which will have to be gained (according to reviews - up to the third delivered air conditioner);
• quality tools.

Equipment for installation of air conditioners should be as follows:

1. Puncher for drilling a wall. The power should be appropriate, since you will have to make a hole of 50-60 mm, into which several pipes will be pulled at once - a cable, two pipes with freon, corrugation from condensate. You can immediately buy an expensive model, for example, Bosch or Makita, to work and not think about repairing the tool. But they choose cheaper ones - Interskol or AEG. The main thing is that power allows drilling concrete or brick - at least 800 watts.
2. A drill for drilling at least 40 mm in diameter. It is better to choose with a reinforced shank, with an impact function. The cartridge formats must match, SDS-max is the best option. Such a product is produced by Hitachi, Sigma. During the installation of air conditioning systems will have to punch holes in concrete, in brick, in natural stone. The drill should work flawlessly.
3. The second hammer drill designed for drilling holes for fastening the external and internal blocks with drills. Mostly will be used with a diameter of 10 and 6 mm. Cordless expensive models are well suited because they hold the charge for a long time, and sometimes you have to work at new facilities where there are power outages.
4. Vacuum pump. You can not use the converted pump from under the refrigerator or something else like that, since the task is to completely drain the system from steam and impurities, and not just to remove the air. If you are engaged in professional installation, you need a two-stage pump to work with two brands of freon. After-sales service will refuse to carry out repair work for free, since the installation will be redone, and the installers will be to blame for this.
5. Manometric manifold. It is advisable to purchase branded digital right away. It is expensive, but the price is justified. Measurement range - up to 60 Bar. The device will check the vacuum and conduct a leak test of the system. In the device’s memory there are up to 60 types of refrigerants, it is possible to add rarely used ones. Especially necessary for large pipe lengths during the installation of industrial equipment - this is for the future.
6. Rolling for copper pipes. Sold in a set. Affect the quality of the connection to the valves.
7. Pipe cutter and device for bending copper pipes, similar to those used for metal-plastic.
8. Wrenches of various diameters. Will be used for mounting blocks outside and inside.
9. Hexagons for unscrewing valves. Without them, it will not be possible to run the refrigerant into the pipes.
10. Screwdrivers for power connection.
11. Level.It is suitable for measuring the inclination of the condenser tube so that the liquid does not stagnate.
12. Wire strippers. If there is, use stripping.

In addition to this list, pliers or a hammer - wooden and metal, as well as consumables - bolts, metal-plastic and copper pipes, wall mounts, freon, oil for a vacuum pump, can be useful.

Many masters avoid the procedure of pressure testing with nitrogen. This is not rational. In the case of installing highways in a suspended ceiling, it will be difficult to find an unchecked leak: you will have to disassemble the ceiling structure. Therefore, it is better not to take risks and buy a nitrogen tank and a reduction gear. These are additional costs, but the work will be done efficiently.

You can buy ready-made sets of refrigeration equipment of various brands. The transportation method is a suitcase with compartments for each tool. The benefit is in price because it is a bulk purchase.

For self-installation of split systems, the above tools will be enough.

Tools for servicing HVAC equipment

Equipment for servicing air conditioners includes:

1. 1. Leak Detector. UV lamps are used. Special glasses are sometimes required if the lamp emits a large stream of light.
   2. Cleaning agents - chemistry. These are acid compounds that brighten aluminum, copper and metal parts. They have antibacterial properties.
   3. Steam generator for professional cleaning. It is better to buy imported - it works longer, heats up better.
   4. The device for topping up freon is a gas station. Allows to do without additional devices - compact and universal.
   5. Refrigerant recovery device. It allows you to work with industrial facilities, has digital pressure sensors and other performance indicators.
   6. Freon cleaning module. It is necessary in the case when the refrigerant needs to be cleaned of accumulated impurities during operation, but not changed. Choose by performance. For household or office systems, they are also used, which helps to save on the purchase of freon.

After-sales service involves the purchase of consumables - freon brands R22 and R410. It’s better for professional installers to buy large cans of refrigerant - it's cheaper.

Equipment for repairing air conditioners

To repair a wall-mounted air conditioner, they first find a problem, that is, they diagnose using the tools described above. Based on the results of the diagnosis, they decide that it is more advisable to repair the unit, part or change. You will need spare parts from a repair kit for air conditioners. Original parts manufactured by the manufacturer of the split system are used.

The most expensive thing is to fix the low-quality work of installers.

Necessary equipment for repair of air conditioners and spare parts:

1. Screwdrivers, hexagons for access to valves.
2. Refrigerant drain to check the circuit for leaks, and then refill.
3. Tools for checking the electrical assembly. Often unprofessional installers confuse the wires and connect them incorrectly, so repair is another connection, only the right one. The tools are the same - a multimeter, a voltage tester, current clamps.
4. Spare parts for the fan - bearings, blades. Replacement is carried out after non-compliance with the rules and terms of service.
5. Replaceable temperature sensors - often fail, so a decrease in performance can happen for this reason.

Serious damage - compressor failure. It is ordered separately and reinstalled. The reason may be the inclusion at low temperatures for heating without a winter kit, wear work if the air conditioner's capacity does not match the size of the room.In cheap models, there is a manufacturing defect of parts, because of which they quickly fail.

Depending on the qualifications of the team and the availability of professional equipment for diagnosis and repair, the process itself can be cheaper or more expensive. The estimate is made after checking the work and determining the problem.

It is not recommended to invite artisans with a minimum set of equipment during the first breakdown - improper diagnosis of the problem will aggravate the breakdown, and repeated repairs will lead to high costs. This is especially true of expensive brands, which are more expensive to service, requires experience and special equipment.
