Condensers and Coils are Vital to Your HVAC System

Published on: May 9, 2012

Each component of your HVAC system is important and especially true for air conditioning equipment. Maintained components reduce the cost of air conditioning repairs over the life of the system. The condenser and evaporator coils are the lifeblood of your system and keeping them clean mean no unwanted air conditioning repairs. Use a professional HVAC contractor to service your HVAC system.

Split HVAC Systems and Packaged Units

Although the term HVAC system is the general category for heating and cooling systems, air conditioning systems are split systems or packaged units. A separate air conditioner unit from the furnace is a split system. An outdoor metal cabinet contains the condenser and compressor, and the indoor cabinet houses the evaporator coils. Additionally, a split system’s indoor cabinet could include the furnace or indoor portion of a heat pump. Installing a split system is the most cost effective.

In contrast, a package central air conditioner unit has the evaporator, condenser, and compressor in one cabinet. A commercial building typically places this system on its roof, and residential structures place the unit on a slab of concrete near the foundation. Often, these systems have electric heating coils or natural gas furnaces. The system does not have a separate indoor furnace.

Evaporators and Condensers

Evaporator and condenser coils work together to cool the interior of a building and remove the hot air. The evaporator coils cool the interior while the condenser coils collect heated air and removes it from the building. An evaporator has cold interior coils and the condenser has hot exterior coils. Both types of coils have copper serpentine tubing surrounded by aluminum fins. Refrigerant, heat transfer fluid, moves between the evaporator and condenser coils by a pump called the compressor.

If refrigerant needs replacing, make sure it is environmentally friendly and does not contain CFCs. Keep the condenser and evaporated coils cleaned and adjusted to minimize air conditioning repair bills.

Whether you need air conditioning repair, service, or overhaul of your HVAC system, contact a HVAC contractor before the summer season and avoid delays in service and expensive air conditioning repairs.
