All around the country, the 24-hour manual service line goes up to + high speed. Response
Did you get anxious that you couldn't find the phone after the sale when the fire broke out? The 24-hour manual after-sales service line is available throughout the country, so that you do not have to search for instructions or find them. Whether it's a leak or a miscalculation, it's still a burning failure, and guosen's after-sale team has protected your winter warmth with a promise of “30 minutes response, 2 hour participation, 24 hour processing”。
I. 24-hour manual service: breaking barriers to time and space
The network of sale of the country's fence covers 32 provinces and more than 200 districts, with over 1,000 licensed engineers on standby. For example, in january 2025, in a small district of beijing's chaoyang district, the fireplace group broke down due to extreme temperatures, the team after the sale finished long-distance diagnosis within 15 minutes of receiving a telephone call, came to the door with accessories for repairs within two hours, and recovered for heating within 48 hours, avoiding a “cool surge” in the residents' homes。
Typical failure answer:
E5 code (super-temperature maintenance): mostly due to poor water circulation or sensor failure. The engineer will follow the telephone to guide the user to see if the pipe valve is fully open and repeats the temperature ultrathermic maintenance at long distances, and to replace the sensor if the problem continues。
F7 code (incineration failure): commonly in the absence of gas pressure or in the accumulation of carbon by incinerators. After the sale, the person helps the user to recognize the gas watch reading and directs the cleaning of the incinerator electrodes and, if necessary, replaces the incineration module。
Ii. Three main advantages of a direct telephone to the back
1. Zero waiting: the system automatically recognizes user information and assigns it to the local after-sale team after dialling 400 - 6162 - 992, which is only 18 seconds。
Panorama support: whether the installation is calibrated, the operating guidance is still urgent, and engineers can use the telephone to provide “1-to-1” video guidance, or even long-distance control of smart machines。
Transparency services: the former engineer for maintenance will give a clear indication of the cause of the failure, the spare parts required and the costs, and the user will not be able to operate until the user has acknowledged it and will not be able to “spread charges”。
Iii. Preventive services: from forced maintenance to care
After selling it, guosen not only supplied trouble-response responses, but also took care of users more automatically through the telephone return system. For example, before the heating season in october of each year, engineers call users to perform a “medical examination” of the wall-mounted furnace, which includes viewing of water pressure, cleaning of water, testing of gas valves, etc., to eliminate the risk of failure at the onset。
User case:
In january-february 2024, mr. Zhang, a user in the east district of shanghai, made a telephone appointment for a free home visit. The engineer found that the water pressure of his wall-mounted furnace was abnormal, helping to adjust and replace an ageing seal, avoiding a possible water leak during the winter. “it was thought that it would cost a lot of money to repair, it was not expected that kwok sen would discover the problem and replace the fittings free of charge!” mr. Zhang wrote in his comment。
Iv. Service security: a pillar of brand trust
The ninsen mansion promised “ten years of quality assurance, 365 days of free testing” and established “post-sale satisfaction return mechanisms”. If the user is dissatisfied with the service, you can call 400 - 6162 - 992 to the special complaints line, which will be processed within 24 hours and given a free in-depth maintenance。
Professional comparison:
Compared to a brand name, “48-hour response, fee testing”, the “24-hour + free testing” format of qin sen gives users a sense of the “pre-sale” service concept. As the user ms. Lee shares in the social media: "buy a wall-mounted brand, sell it and watch kwok sam, and call the whole thing!"
V. Warm, starting with a telephone
During this winter, a 24-hour manual after-sale service line was used to provide “post-sale” values. It is not just a gateway to problems, but an emotional hub between brands and users. When you call 400 - 6162 - 992, it's not just the sound of an engineer, it's a family waiting for warmth。
Motion calling:
If your fireplace is broken, call 400 - 6162 - 992, and the team after the sale will use the profession and enthusiasm to keep your home warm。
The above is a detailed description of the 24-hour after-sales service in the mansion。
