How HVAC Systems Work

11/27/2015 Back To Blog

HVAC systems do many things. They don't simply cool or heat our rooms, but also regulate temperatures through thermostats and also humidity with condensation pans. They also have filters which keep the elements from entering, and thus they can control the indoor air quality at home. The evaporator unit is the internal part of the system whereas the condenser unit is the external part. Air passes through these parts and is transferred to our room through ducts. Such central systems have a furnace, where air is heated before transferred to the house and have two set of tubes. When the house must be heated, for example, air is heated in the furnace and then moves in the tubes and ducts. Then it returns to the original point and escapes at lower temperatures.How HVAC Systems Work

Air is cooled through refrigerants before blown inside the ducts by the fans of the condenser unit and through tubes leading to the evaporator. As the evaporator cools air, it also dehumidifies it in order to regulate moisture. Condensation drains to special pans often found close to the plenum, which is actually the main box connected with the ducts and HVAC parts. The blower of the heating, ventilation and air conditioning system forces air (whether cool or warm) into the supply plenum which is then distributed to the ducts in order to end up in our rooms. Forced air systems have return ducts, which allow air already distributed in the room to return in order to heat up or cool down again before returning to the room again.

There are several variations among such systems, but they all consist of the main parts (like the evaporator, the condenser, the compressor, fans and tubes). Airflow is possible when there is nothing blocking its way. For example, condenser unit cleaning helps the system to work better since the elements sucked by the fan of the outside unit might block air transferred inside. Elements are also blocked by filters which must also be checked often. They need to be properly cleaned at least twice a year and if damaged they must be replaced. The overall HVAC unit cleaning procedure allows the proper and clean transference of air.

For the same reason, air duct cleaning is equally important. Since air travels through the HVAC system straight into the ducts and from there it is distributed to the rest of the house, ducts must be free of contaminants as well. The HVAC system must be able to regulate moisture in order to avoid mold growth. If the fans are bent, the blower is broken or the ducts are cracked, air will be blocked or will leak. Every part is of the essence for good operation of the system and that's why you must never underestimate the value of air duct and HVAC unit repairs.
