In order to function efficiently, your HVAC system needs regular maintenance. This is because your outdoor central air unit can accumulate all sorts of dirt and debris that must be periodically cleaned. If not, it can impede your system’s performance and cost you a fortune in energy bills. So, how do you handle HVAC cleaning? The simplest answer is to hire a professional. Here are some steps your HVAC technician will take when cleaning your outdoor central air unit:
Clean the condenser. After shutting off power to the system, your HVAC technician will vacuum the condenser fins, and then wash away any excess debris with a hose. He’ll also straighten any fins that may have been bent or crushed. Bent fins restrict the airflow from your unit, wasting energy.
Clean the fan blades. Removing dust and dirt from your system’s fan blades is fairly simple — they just need to be wiped down with a wet rag. However, your HVAC technician will do more than just clean. They’ll also tighten the blades and belt, lubricate the blower and make sure the motor is going in the right direction.
Clean the drain tube and condensate pan. Your HVAC system dehumidifies the air as it heats or cools your home. As such, it accumulates an enormous amount of moisture. To prevent it from growing mold or algae, your technician will drain the condensate pan and clean it out, and then remove the drain tube and flush it out with water.
Replace the air filter. This is something you should do regularly. If your filter gets clogged, not only will it restrict airflow, it will also circulate dust, mold and other contaminants through the system. Your air filter should be checked every month and replaced at least every three to six months. However, an HVAC professional can give you a better idea of how often you should replace your filter, based on your home’s specific needs.
