However, there are certain things that you can or should expect when an HVAC contractor visits your home. In fact, it is a good idea to have knowledge of the things that you can expect when you call an HVAC contractor. This is because if you are aware of the things an HVAC contractor is supposed to do you can challenge them if you think that they are not doing their job as per the expected norms.
First of all an HVAC contractor should start with systems check. This will involve checking all the system functions and safety controls to ensure that the system is functioning well. In case it is required they will have to make the necessary adjustments so that the system does not face any operational problem.
The system check of an air conditioner takes place step by step. First the contractor has a look at the outdoor unit that is the condenser and does all that is necessary to ensure that the condenser does not have any problem. Along with the mechanical components, the electrical components are checked as well as part of the safety measure.
The next step is checking the indoor unit or the evaporator coil. Along with thoroughly cleaning the coil, it is checked for any sort of biological growth like mold because mold has an adverse impact on human health. As part of routine maintenance it is mandatory that the air filters of the air conditioners are replaced because dirty filters have the potential to reduce the efficiency of the air conditioner.
