If your AC unit has been running poorly, you need to check the drain line frequently. Water can back up inside the unit, making it useless. Using a shop vacuum to clean it can remove the dirt and debris. Once the drain line is clear, you can recharge the refrigerant, if necessary.
Another quick and easy fix for your HVAC is to change the filter. The airflow from the vents is affected if the filter is clogged. A dirty filter prevents warm air from reaching the vents. A damaged filter can also affect the performance of the blower, slowing down airflow.
If your air conditioner runs continuously but doesn’t have any airflow, you might have a malfunctioning thermostat. A malfunctioning thermostat can cause many HVAC issues. To prevent this, make sure the thermostat is working. If it isn’t, you need to replace it. Checking the thermostat can be the solution for a number of common HVAC issues.
If you notice that the airflow from your HVAC system is reduced or stalled, it’s time to change your air filter. A dirty filter will prevent the airflow from reaching the entire system and reduce the efficiency of the system. The first step in this process is to remove the old air filter. Locate it and purchase a new one that is the same size and rating as the old one. The old filter will have the dimensions printed on it. Also, make sure the arrow on the filter points towards the direction of airflow.
