2 Types of HVAC Systems and Installations

Heating, ventilation, and air conditioning (HVAC) systems help residential and commercial property owners regulate temperature, humidity, and air quality in their buildings. There are different types of HVAC systems suited to different needs and preferences.

The techniques in HVAC installation differ depending on the HVAC type. Here are two common HVAC systems and their installation methods:

1. Furnace and Air Conditioner (AC) Combo Units

Furnace and AC systems are a traditional combination ideal for homeowners who want a separate heating and cooling system. Furnaces run on natural gas, oil, or electricity, while all ACs run on electricity. HVAC installation for a furnace and AC combo unit is easier when both systems are electric as installers do not have to install a separate gas or oil system for your furnace.

Installing an electric furnace and AC combo is also safer as it eliminates the risk of gas and oil leaks, which can be hazardous. It is also more cost-effective as you only need access to electricity to operate your HVAC system. Here is how HVAC technicians install furnace/AC systems:

Home Assessment and Planning

When you hire an HVAC company to install your system, they send technicians to inspect your property to determine the right size HVAC. The technicians also check your property’s layout and take measurements to determine where to install ductwork. The HVAC system can circulate hot and cool air into your home through that ductwork. 

Mapping out the ductwork in each room before installation allows the HVAC technicians to place the ducts strategically. This reduces the distance that cool or warm air needs to travel, preventing energy loss. Planning the ductwork also reduces temperature variations in different rooms. Installers also determine a central place to mount the thermostat to get accurate readings.

System Installation

HVAC technicians begin by installing the ductwork throughout the building. Installers may place your HVAC’s electrical system first if there is a risk of conflicts between the electrical system and the ductwork. After installing the duct systems, HVAC technicians install the system’s indoor and outdoor units and connect the AC’s refrigerant lines and drainage pipes. They then power the system to test its heating and cooling functions. 

2. Ductless Mini-split Systems

Ductless mini-split systems are beneficial due to their flexibility and energy efficiency. These HVAC systems combine a heating and cooling system into one unit which helps reduce installation time. They do not require ductwork for air distribution, making them ideal for installations in older buildings. You can also install a ductless mini-split system as a room addition where installing ductwork is inconvenient. Here is the installation process for ductless mini-split HVAC systems:

HVAC Selection and Site Preparation

It is necessary to choose the right unit size for adequate heating and cooling. Your HVAC technician can guide you on the right unit size based on your home’s square footage. Once you select a unit, installers inspect your home to determine the best place to mount the indoor units. They also install an electrical system with enough amperage to power your unit.


HVAC technicians install the indoor unit on a wall connected to your house’s exterior. The wall must be free of obstructions and in an area with minimal sunlight exposure to avoid interfering with the system’s ability to read indoor temperatures. Installers then mount the outdoor unit to a wall or on the ground in an area clear of bushes and other obstructions. They then connect the line set through which refrigerant flows from the outdoor unit to the indoor unit. 

Get Professional HVAC Installation Services

When installing an HVAC system in your home, hire a professional with experience with diverse types of HVAC systems. Your HVAC technician can help you select the right unit size and install the system according to building regulations and safety standards. After installation, the technician tests the system for optimal functionality and gives you tips to maintain your system.
