For the most part, the maintenance of air conditioners does not require a teacher. Smaller wind, slower cooling, internal dripping, with three first steps of self-checking: cleaning of filters, inspection of off-sites, plumbing. The problem of high air conditioners in the summer could be solved by doing so; professional maintenance was required only if the air conditioners were not cooled after clearance or repeated failure to report. This paper removes the steps and maintenance points and saves you money。
01 poor refrigeration: first filtering and exterior, no fluorine deficiency
The air conditioner's not cold. The first thought was fluorine? In fact, filter blocking is the number one reason. Dismantling the inner panel and removing the filtration net will significantly restore wind power if the area is covered with dust and dried with water. This is a free and immediate operation。
Re-watching outdoor machines: refrigeration capacity can be significantly reduced if it is blocked by miscellaneous items, pirated nets or dense green plantations, where heat is blocked. Remove the shield and ensure ventilation around the outside. If the filters and off-sites are still uncool, contact the master to detect the chiller pressure - and in most cases not at all。
Basis of judgement: filter congestion is not only small, but may also cause evaporationers to freeze or even trigger e2 protection. It is recommended that filters be cleaned on a daily basis, with a high degree of environmental encryption. For renters or old air-conditioning users, self-cleaning can solve most of the troubles; those who are able to do it are perfectly competent, and the hands-on parties do not worry about breaking the filter simply by opening the panel and using the tools throughout the process。
02 inner drip leak: most of the pipes are blocked, so don't mess with the machine
During the summer, the humidity is high, and if the water is not drained, it spills through the inner machine. There are two common reasons for this: the drain pipes are blocked by sludge or slurry, or their bending leads to a lack of flow. When problems are identified, the power supply is cut, the drainage pipes are smoothed, and any plugs are checked. If it's not too deep, pick it out with wire or toothpicks; it's too heavy to flush with hoses。
Note: do not self-write the water or remove the inner shell. The water supply is well located and worse if the leak is broken. Drainwork is delicate, and it's worth a few dozen dollars to find a master when you can't handle it. However, while leaks do not affect cooling, delays can damage the surface floor and be addressed as soon as they are discovered。
03 good routine maintenance, half-failed: filters, wind delivery, off-site cleaning
The air conditioner wasn't fixed, it was raised. For the first time in a new season, the wind mode will run for 10 minutes and the internal tide will be drained to avoid bad taste. The exterior condenser washes once a year before the summer and clears the wings with a soft brush or a low-pressure water gun, willow and dust, preventing frequent stoppages caused by overheating protection。
Safe red wires: power plugs must be removed before cleaning, and the internal circuit parts cannot be washed directly by water; volatile liquids such as diluents, gasoline can damage the shell and can only be wiped with neutral detergents in soft cloth。
Also, if the air conditioner has a screen failure code, there is no need to panic. E1 (internal and external communication failure) is common in branded variant air conditioners such as conja, which can be rebooted with power outages, e2 (vulner ice protection) is mostly too dirty for filters, and f begins with temperature sensors. Repeatedly miscalculation or stoppage and then call master。
04 discreeted: what about the parties, the center, the old owners? Select
• users who are capable of doing it: daily cleaning of filters and the removal of drainage pipes can be done by themselves, with no cost of a few dozen to hundreds of dollars at a time. The provincial party, which is afraid of troubles, has an appointment every year at the end of the season for a professional depth clean-up, with emphasis on checking the sewers and coolers. Domestic air conditioning has been in use for more than 10 years and is frequently problematic, and no further major repairs are recommended, and the cost of electricity is saved by switching to the new national standard-i energy efficiency model。
05 common faq
Is it fluorine-deficit if air conditioners don't cool
Not necessarily. Most cases of non-refrigeration are caused by filter congestion or external heat dispersion, which can be addressed after cleaning. Refrigeration is necessary only if it remains uncooled. Domestic air-conditioning is less effective in refrigeration, and fluorine deficiency is usually at the end of the screening order。
Can you fix the air conditioning leak yourself
Yes. The power supply is cut first, the drainage pipes are checked for bending or being blocked by stupor, most of which can be resolved after clean-up. However, no self-dismantling is recommended for the recharging and interior structures, and the cost of later maintenance is higher in the event of damage. If you can't handle it by yourself, go to master。
How often do air-conditioning filters wash
It is recommended that this be done once a month, with an appropriate increase in frequency in the dusty environment. Take out the filters and wash them with fresh water and dry them back. When cleaning, be careful to remove the power and not touch the inner wings with your hands to avoid scratching。
