What is an HVAC Pump?

Keith Koons

Heating ventilation and air conditioning (HVAC) is a contemporary concept designed to regulate the temperature and quality of the air as well as level of humidity in commercial and residential buildings. The practical face of this technology is the HVAC pump, which performs the heating, cooling and dehumidifying functions through its two main components: the external condenser and an internal evaporator coil. Installing multiple systems in a single unit makes it a cost effective and efficient choice as compared to the traditional heating and cooling options. Apart from resulting in a significant reduction in consumer electricity bills, it also helps customize the climate within the room through insulation and constant filtering.

One of the first aspects governing the purchase of an HVAC pump is a close scrutiny of the equipment, which comes in a variety of dimensions. The size of the HVAC equipment generally determines its capacity; while a unit meant for home use would be typically small, one being purchased for industrial requirements would be much larger and bulkier.

HVAC systems can generally be categorized into four different types based on their method of operation and the design of the space in which they will be installed. An HVAC pump can be a furnace and condensing system, a heat pump and fan coil system, a zoning system, or a combination of each. Another innovation within the field is the introduction of more sophisticated HVAC system that has the added advantage of being eco-friendly as well.

For an HVAC pump to keep the occupants of a room cool in summer and warm in winter, preventative maintenance in the form of regular checks by a certified expert is a must. A routine inspection includes a complete examination of the unit, an estimate of the extent of wear and tear, cleaning the air filter, and replacing parts as required. In case of a sudden breakdown, assistance should be sought only from qualified professionals in the field. It is imperative for an HVAC owner to realize that because HVAC repair is a specialized industry, many repairmen are not licensed to diagnose or service an HVAC pump.

When compared to older HVAC pump models, modern HVAC models are more consistent and reliable in terms of performance and safety. One of the more recent major technological advancements is the replacement of the traditionally used Freon® with more eco-friendly refrigerants to help conform to various government regulations. As a result of this research, it is not only the HVAC pump, but also the entire range of HVAC products that are being redesigned to achieve both energy efficiency and a safer planet.
