AC and HVAC: What’s the Difference?

Katy AC RepairAlthough the acronyms AC and HVAC are often used interchangeably, they have different meanings. AC stands for air conditioning, referring to equipment that creates a cool indoor environment. HVAC stands for heating, ventilation and air conditioning, referring to a mechanical system that performs several functions for indoor climate control. Licensed Katy AC repair and installation contractors provide a full array of HVAC services for communities in the greater Houston area.

Elements of HVAC Performance

An HVAC system includes a furnace that provides heat during cooler months and an air conditioner that cools the air during hotter months. However, it also does much more. Ventilation is an important part of indoor comfort. Because newer homes are more air-tight, there are fewer leaks in the building envelope. This can trap airborne pollutants inside the building, causing indoor air to become stale. Increasing ventilation improves air exchange, bringing in fresh, outside air and expelling stale air.

Regulating humidity is another important role of an HVAC system. Humidity control is important in Katy and Spring, Texas, where humidity averages 75 to 90 percent. Too much humidity makes rooms feel clammy and uncomfortable. Poor humidity control may allow mold to thrive in ducts, filters and the living space. In the winter, heating dries the air, which can cause respiratory problems.

Professional Katy air conditioning repair services include evaluating the indoor air of your home or business. Recommended equipment that works with HVAC systems to improve ventilation and indoor air quality, include:

  • Whole-house ventilators
  • Humidity control devices
  • Air purifiers
  • UV lights
  • Air filters

Types of Air Conditioners

Because the Houston area has warm weather most months of the year, residents rely on air conditioning for indoor comfort. There is not a one-size-fits-all air conditioning unit because every property is different. There are several types of heating and cooling equipment and Katy AC repair services to suit your needs and budget.

  • Ductless mini-split units provide conditioned air in rooms that cannot be connected to ducts. They are quiet, energy-efficient and easy to install.
  • Heat pumps move heat from one place to another instead of using energy to heat and cool. Flipping a switch reverses the flow of refrigerant, removing heat from indoors during the summer and bringing it indoors during winter. They provide excellent humidity control and are energy-efficient.
  • Ducted systems send conditioned air to rooms through ducts. Both heat pumps and traditional furnaces and air conditioners can be used in a ducted system.

Air Depot’s NATE-certified technicians service all brands of heating and air conditioning equipment and provides an array of Katy AC repair services.
