The technician will use gauges to check the pressure and adjust it according to the specifications of your specific air conditioning unit.
Besides ensuring adequate refrigerant levels, preparing your air conditioner for the summer involves a number of other important steps. Begin with cleaning or replacing the air filters, which ensures that your system operates with maximal efficiency and air flow. Dirty filters can restrict air flow and reduce the system’s efficiency, leading to increased energy usage and costs. Next, inspect and clean the condenser and evaporator coils. Dirty coils can also hinder the efficiency of the air conditioner and cause the system to work harder, which in turn, elevates energy consumption.
Also, check the thermostat and controls to ensure that they are working correctly. If your thermostat is outdated or malfunctioning, it might be wise to upgrade to a more energy-efficient model or a smart thermostat that allows for better control of cooling. Additionally, clearing the drain lines and checking for leaks is crucial; clogged drain lines can cause water to back up, leading to damage and potentially, mold issues.
Finally, ensure the area around the outdoor unit is clear of debris and has adequate air flow. Trim any bushes or shrubbery that might block the airflow to the unit. Properly preparing your air conditioner not only improves its efficiency but also extends the life span of the unit, ultimately saving money and ensuring comfort throughout the hot summer days.
