Even though I have been in this industry for a long time, I still see new things and new issues every day.
Last month, we scheduled an appointment at certain premises. The customer had contacted us saying that her new air conditioning had malfunctioned. She was worried that the ac workman had done a low-quality job. She complained that it was too early to perform the annual a/c service and we agreed with her. When we visited the premises, we noted that there was an issue with the air conditioning installation. The HVAC unit had been fitted in the wrong place, where there was no free airflow. This situation had caused the ductless multi-split as well as the dial thermostat to malfunction. The customer had opted to get air conditioning technicians online as opposed to from the local business. This had cost her as the engineers did a very shoddy job. These amateurs did not know more about air conditioning than I did. Though they got a legit unit from the air conditioning supplier. My colleague stated that he had seen a lot of these cases but only when installing commercial air conditioning systems as most commercial buildings lack the space to house an entire system. After we re-fitted the unit, we advised on the importance of handling the air conditioning repair services as well as the air conditioning maintenance. One of the other issues that are related to installation is having the wrong size unit. Most homeowners are under the impression that big units are more efficient and this cannot be further from the truth.
