1. What is an HVAC system?

HVAC systems are complex systems of equipment designed to regulate temperature and humidity in homes or commercial spaces and make informed decisions when investing. To get the most out of an HVAC investment decision, you must understand critical terms and concepts to make an informed choice.

HVAC systems include air conditioners, heat pumps, furnaces, ductwork, and thermostats to create a comfortable indoor environment for residents or tenants and enhance indoor air quality by filtering out toxic waste and allergens from the atmosphere. The goal is to make life comfortable.

2. What is an air conditioner?

Air conditioners cool indoor air by passing it over coils filled with refrigerant to remove heat and humidity, repeated until the saturation point of the refrigerant has been reached.

Before returning to the indoor part of the system, water passes through an evaporator coil to absorb both heat and moisture before being returned as evaporated water.

The air handler then disperses conditioned air throughout the building via ductwork, with all air ducts sealed and insulated for optimal energy efficiency. Optional features of an air handler may include energy-saving switches, “check filter” lights and oscillating vents to distribute air more evenly.

3. What is an air handler?


Air handlers resemble large furnaces and serve as indoor components of heating, ventilating, and air conditioning systems. They work alongside outdoor units like electric heat pumps and air conditioners to circulate conditioned air throughout your home.

An air handler includes a blower that circulates conditioned air throughout your home’s ductwork and filters that remove airborne debris to make your system run more efficiently.

In addition, there are cooling coils in summer and heating elements in winter to create a cycle that helps your ideal temperature and humidity levels remain balanced.

4. What is a ductless system?

Ductless systems, more commonly referred to as mini-splits, are an air conditioning option that does not rely on ductwork for its operation. Instead, refrigerant is piped directly from an outdoor compressor to compact indoor units equipped with air handlers and evaporator coils to cool air before returning it through a wall-mounted unit.

Mini-split technology offers many advantages over other forms of AC systems, including greater controllability. You can set each unit’s temperature remotely using line-of-sight remotes; some even feature Wi-Fi connections so you can stay in contact with it at all times.

Ductless mini-split heat pumps can be an economical and energy-efficient choice when adding or renovating a home. Furthermore, these heat pumps allow for greater control over individual room temperatures as well as being up to four or four and half times more energy efficient than furnaces, boilers or baseboard heaters when operating in heating mode.

Ensure your ductless system is appropriately sized to avoid short cycling and unnecessary energy waste.
