Are you looking to hire an HVAC installer but want to know what to expect? From installing new units to maintaining existing ones, these professionals play an important role in keeping homes and businesses comfortable all year round. In this article, we’ll delve into what they do so that you can better understand the process.

What Does an HVAC Installer Do?

HVAC stands for Heating, Ventilation, and Air Conditioning. These systems in residential houses and commercial buildings not only keep temperatures at comfortable levels but can also maintain healthy humidity levels. Air that is too dry dries out your skin and often makes it more difficult to breathe. Air that is too humid increases your chance of mold and mildew. So maintaining temperature and humidity are pretty important!

Do Professional HVAC Installers Have Licenses?

Yes, professional HVAC installers are required to have a license to work. Depending on the state they will need different certifications and training to obtain a license. The certification process may require refresher courses and an exam every few years for the installer to remain certified. 

In addition, most states also require liability insurance before any installation can take place. It’s important for homeowners or businesses looking for an HVAC installer they check their credentials and make sure everything is up to date.

What Are the Different Kinds of HVAC Systems?

Forced Hot Water Systems

Hot water heating systems use hot water to heat your home. They have a boiler that heats up the water and a heat pump that sends it through pipes throughout the house. The hot water, flowing through radiators, warms up each room, keeping you and your family comfortable during the colder months.

Often these systems have super cost-efficient insulated storage tanks to hold the water once it’s heated to reduce the heating cost.

Geothermal heat pumps

A Geothermal HVAC system uses energy from the ground to heat or cool your home. It pumps hot or cold air into your house, (depending on the season), using a special type of pipe buried underground. The system works by exchanging energy between the ground and your home. Since the temperature deep underground stays relatively stable, you can use it as an air conditioner in the summer and a heat pump in the winter.

Forced Hot Air

Forced hot air heating systems use hot air to keep your house warm. The furnace heats up the air and sends it through ducts in the walls. Then the hot air is blown into each room of your house to make it nice and cozy when it’s cold outside.

However, while it’s nice to have warm air circulating through your house, many people find this kind of heat to be too dry. Plus, these systems require air duct cleaning as well as space to run the ducts for both heating and cooling.

Mini-Split Systems

Ductless mini-split systems use small decorative indoor units and an outside unit; together they delivers heated, cooled, and dehumidified to the conditioned space. 

Central Air Conditioners

Air conditioners are a popular choice in many homes. A central air conditioner provides efficient cooling by using a refrigerant to transfer heat from the inside of a home to the outside air.

This is accomplished through two main parts: an outdoor compressor unit, which compresses and circulates the refrigerant, and an indoor coil unit, which receives the cooled air and distributes it throughout the home.

Central air conditioning units are connected to a thermostat, allowing you to control the temperature without having to adjust the system manually. Additionally, central air conditioning units are designed to remove pollutants from the indoor air, making them ideal for allergy sufferers or those with respiratory issues.

What Kind of Services Do HVAC Installers Provide?

HVAC installers provide a variety of services including installation and maintenance of heating and cooling systems, such as furnace systems, boilers, heat pumps, air conditioners, and humidifiers.

These professionals can also help upgrade or replace existing HVAC systems with the latest energy-efficient models that save money on energy costs. In addition to installation services, they may also offer repair services when needed. They typically work with a range of materials including copper tubing and galvanized steel ductwork.

They are also knowledgeable about ventilation issues so they can prevent potential problems associated with mold growth due to humidity levels.


When it comes to HVAC systems, there are a variety of options for homeowners. From forced hot water and geothermal heat pumps to central air conditioners, each system has its own advantages and disadvantages. It’s important that you understand each option’s pros and cons before investing in your home’s comfort. Furthermore, having access to qualified installers who can provide installation and repair services is essential when selecting any kind of heating or cooling system. With the right information and professional help, you’ll be able to find the perfect solution for keeping your home comfortable all year round!
