After the repair is still bad, the central air conditioning service is very important

The scorching heat of summer forces us to seek refuge under the central air conditioner, but after prolonged use, these systems can develop issues. When problems arise, many people simply call in the after-sales service team. However, it's not uncommon for the unit to break down again after repair. Why does this happen? Let’s take a closer look. **1. Over-Repairs and Unnecessary Replacements** Many users who have bought commercial central air conditioning units may experience issues such as poor cooling performance, refrigerant leaks, or excessive noise after some time. In such cases, they often contact the after-sales service team. But for those outside the warranty period, they might opt for a local repair company. Unfortunately, unprofessional technicians may perform multiple repairs without properly diagnosing the real issue. They might replace various parts unnecessarily, leaving the problem unresolved and even causing more damage. This not only wastes time and money but can also render the system completely unusable. **2. Fake Brand After-Sales Service** Another common issue is encountering fake or unqualified after-sales service providers. Some small companies may claim to be authorized dealers or official service centers of well-known brands. Without proper verification, users risk falling into their trap. These companies may lack the technical expertise required for proper maintenance. As a result, instead of fixing the problem, they could make it worse, leading to further breakdowns or even making the unit inoperable after the so-called "repair." **3. Choose a Professional Installation and Maintenance Company** It’s often said that “a central air conditioner is 30% product and 70% installation.” This highlights how crucial professional installation is. If the unit was installed correctly from the start, it should function smoothly for years. If issues arise later, users should contact the manufacturer’s designated after-sales service team. Even if you decide to go through another channel, make sure the company has the proper certification or carries an official brand logo for central air conditioning maintenance. This ensures you’re getting quality service and protecting your investment. By being cautious and choosing the right service providers, you can avoid unnecessary breakdowns and extend the life of your central air conditioning system.
