We often mention the central air conditioning cleaning and maintenance, naturally think of is the related matters of the central air conditioning machine, many people often ignore the cleaning and maintenance of the central air conditioning machine, the external machine is as important as the internal machine, in long-term use is also the need for regular cleaning and maintenance. So how much does it cost to maintain the central air conditioner? Next central air conditioning maintenance Xiaobian to discuss with you.

First, does the central air conditioner need maintenance

Due to the requirements of the location of the outdoor unit heat dissipation, there may be debris left inside the outdoor unit. If it is not cleaned in time, it may affect the life of the fan blade and cause the fan blade to crack. For a long time, because the fan speed is relatively fast, the fan blade may fly out and damage other parts in the machine. The finishing work includes checking the screws of the frame. If they are loose, they should be tightened and reinforced. If the frame is found to be seriously rusted, the housing should be replaced immediately.

It is necessary to check the outdoor unit condenser fins regularly to ensure that the fins are upright, and no inverted pieces are allowed to occur. If so, the air conditioner fin carder or tweezers and pliers are used to carefully trim the fins.

Central air conditioning cleaning and maintenance needs about 50-200 yuan/unit, of course, this is only a small cleaning. If it is a large cleaning, the outdoor unit is generally 400-600 yuan/set, the indoor unit is generally 100-300 yuan/set, blowing water, fluoridation, system debugging, equipment maintenance, etc., also need to add money. This is the approximate price range, and the fees will be a little different in different regions.

Second, how much is the maintenance of the central air conditioner

The VRV system host is about one thousand, in addition to the end 50-100, the water system depends on the brand model and the use area of the host, generally 20,000 to 50,000 a year.

Third, central air conditioning external unit location selection and installation suggestions

1. Select a place where ventilation is smooth;

2, the selection can ensure that the inlet and outlet air have enough distance, while not any obstacles, in order to facilitate the heat dissipation of the external machine;

3, do not choose in the bedroom window or near the bedroom, to prevent noise interference;

4, choose the location near the indoor unit to shorten the refrigeration pipeline and save costs;

5, choose no smoke or other corrosive gas position, to prevent damage to the external machine;

6. Select a position where the weight is more than 2-3 times the weight of the outdoor unit;

7, the height of the outdoor unit should be as low as possible than the indoor unit, the height difference is generally within 5000mm, if possible, can be installed on the ground, or installed on the tightening platform that will not produce noise;

8. A rubber shock absorber or strip of rubber with a thickness of less than 10mm should be set under the base to maintain the stable operation of the outdoor unit;

9, the inlet and exhaust air should be smooth, to avoid backflow phenomenon, the outdoor unit against the wall side should leave a gap of more than 200mm, the heat exchanger to create good heat exchange conditions.

10, in the street ground installation, the bottom of the unit must be more than 2500mm from the ground, can not impede traffic and passers-by walking, outdoor unit discharge of hot (cold) wind, can not be close to the neighbors or passers-by, if necessary should be set up a guide fence plate.

11, in view of the coastal areas of air pollution and acid rain is more serious and the air contains more salt, under the premise of not obstructing air circulation, to install a sunshade, to avoid outdoor units by direct sunlight and rain, to improve the refrigeration effect of the unit and prevent outdoor unit rust.

12, Kunshan central air conditioning maintenance in the upper level of the integrated building installation of outdoor units, drainage, including condensate water should be connected to the building's centralized sewer pipe, so as not to affect the normal life of the downstairs and passers-by walking.
