HVAC refers to the different systems used for moving air between indoor and outdoor areas, along with heating and cooling both residential and commercial buildings. They are the systems that keep you warm and cozy in the winter and feeling cool and fresh in the summer. They also are the systems that filter and clean indoor air to keep you healthy and maintain humidity levels at optimal comfort levels.

Different types of HVAC Systems
- People living in hot or cold climates might go for a single stage system, designed to produce just heating or cooling. These tend to be inexpensive, but are also rather inefficient and will typically be working at capacity even when it’s not required. .
- More advanced models will offer variable fan speeds to cut down on power use, however they remain inefficient when compared to multi-stage systems, and are thus more expensive to run over the long term.
- Zoned systems, on the other hand, have been designed to heat or cool individual parts of your home. This is done by designing zone valves and dampers inside the vents and ductwork that selectively block the flow of air. For people with larger properties this is of immeasurable value as it prevents the system from heating or cooling areas in the home that are not in use.
- HVAC systems can also be built to offer humidity control, and both humidifiers and dehumidifiers can be added as options to heating and cooling systems. People that live in very dry environments or the tropics find these additions to the system essential. With that being said, some people prefer to install separate humidifier or dehumidifier systems, so that they can manage the humidity of their environment without also having to turn on the air conditioner.
Heating systems
Heating systems can take a couple of different forms. Some are furnaces that burn material to provide heated air through the ductwork, while another popular choice is boilers that heat water for steam radiators, or forced-water systems with baseboard radiators, electric heat, and heat pumps. A furnace will generally operate on natural gas or propane, while a boiler will use gas or oil to heat the water.
Another option is a radiant floor, also known as a hydronic heating system. These use piping under a floor, and are made up of flexible tubes that are filled with water or a glycol solution. These can heat any kind of floor, including concrete, and are an efficient method of providing warmth in a home. They can even be retrofitted into wooden flooring, though they need to be carefully installed in sheathing for wooden floors.
Cooling systems
Air conditioners come in many forms, from the massive boxes designed to cool an entire house to a portable window-mounted box that can be pulled out and used in cooler climates to handle short summers.
Many air conditioners can even be installed by the owner, with ductless mini split systems a popular choice. Installation is still a major project, as the interior and exterior elements of the system need to be properly connected, but they are relatively inexpensive to buy and run.
For dryer climates, evaporative coolers are a popular choice. They draw outside air into the system, passing it through water-saturated pads, which cool and moisten the air before pushing it into the living space and displacing the hot air.
