Maintaining Your Air Conditioner

, , Comment closed

HVAC maintenance goes a long way to keep your heating and cooling unit functioning properly, safely, and running at maximum energy efficiency. Unfortunately, some preventive maintenance plans do not cover the correct refrigerant charge or proper airflow.

Refrigerant Charge

The refrigerant charge of your air conditioner is the amount of refrigerant in the system. If this charge is not at the manufacturers’ recommend level, the air conditioner cannot perform at its peak efficiency. Furthermore, if a qualified technician does not perform the HVAC maintenance the refrigerant charge problems could go unnoticed or problems become worse by the unqualified technician adding refrigerant when it is already at its maximum level. The best way to ensure your AC functions properly is to have a trusted air condition repair company maintain your unit.


Over time, the air conditioning coils and air filters will become dirty, restricting the airflow and causing the air conditioner to work overtime to keep your home cool. If not regularly maintained with HVAC maintenance, the dirty coils and air filters will lead to premature failure of the air conditioner fans and compressor.

If the refrigerant charge is not at the correct level or the airflow is restricted, your unit will work harder which ultimately causes the HVAC unit to malfunction and shortens its lifespan. Furthermore, improper refrigerant charge and airflow restriction increases your energy use, which in turn causes you to pay more for your monthly utility bill.

The best way to ensure the technician performing your HVAC maintenance is well trained and experienced with refrigerant levels and airflow is to ask them about their maintenance process. Typically, manufacturers recommended that the HVAC technician measure the units’ airflow before checking its refrigerant charge. If the airflow is not correct, the refrigerant level is not accurate. Along with the refrigerant charge and airflow, the technician will also check for leaks and ductwork problems, and ensure the electric controls, connections and electrical terminals are properly connect. These are just a few of the things the technician will check and repair during the HVAC maintenance process.
