Problems such as lost opportunities due to door failures can also be avoided.<\/p>\n<p>2- Maintenance of comfort: The performance of the automatic door device that repeats opening and closing each time a passer passes is continually deteriorating. By carrying out periodic inspection and maintenance, it is possible to maintain a comfortable state at the beginning of installation for a long time.<\/p>\n<p>3- Extension of service life: Periodic inspection and maintenance and appropriate preventive maintenance prevent sudden failures, prevent equipment performance degradation, and slow down the overall deterioration rate of the equipment.<\/p>\n<p>4- Ensuring safety: In addition to daily inspections, regular inspections and maintenance by specialists will ensure that you can always use the automatic door safely and securely.<\/p>\n<p>5- Reduction of running costs: By carrying out regular inspection and maintenance, sudden expenses can be avoided. Carrying out appropriate repairs in a timely manner extends the life of the equipment and does not lead to major repairs, resulting in a reduction in total costs.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-large wp-image-15034\" src=\"https:\/\/sonha.com\/wp-content\/uploads\/2025\/04\/after-sale2-1024x576.jpg\" alt=\"\" width=\"1024\" height=\"576\" srcset=\"https:\/\/sonha.com\/wp-content\/uploads\/2025\/04\/after-sale2-1024x576.jpg 1024w, https:\/\/sonha.com\/wp-content\/uploads\/2025\/04\/after-sale2-300x169.jpg 300w, https:\/\/sonha.com\/wp-content\/uploads\/2025\/04\/after-sale2-768x432.jpg 768w, https:\/\/sonha.com\/wp-content\/uploads\/2025\/04\/after-sale2.jpg 1536w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Details_of_Inspection_Maintenance_Services\"><\/span>Details of Inspection &amp; Maintenance Services<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<table style=\"width: 100%;\" border=\"1\" cellspacing=\"0\" cellpadding=\"0\">\n<tbody>\n<tr>\n<td style=\"width: 31.318%;\">\n<p><strong>\u00a01.
