Buying an HVAC System? 5 Things You Must Know

HVAC stands for heating, ventilation, and air conditioning. Residential and commercial buildings are heated and cooled using this technology. These types of systems can be found in a variety of places, from single-family houses to submarines, and they provide environmental comfort. Therefore, one of the most significant investments you can make for your house is a new HVAC system as it will not only support the care of your comfort but also your loved ones’ health. Our Greenville heating and air professionals will help you out making the best purchase!

Because of the significant influence an HVAC system can have on your family, it’s important to make an informed decision. For example, if your HVAC system isn’t powerful enough, it won’t be able to heat or cool your home effectively, resulting in an uncomfortable living environment. Choosing a system with too much power, on the other hand, can waste energy and cause it to shut off and on incessantly, which can be annoying.

Here’s what you should know before buying an HVAC system so you can make the best decision possible.

Choosing the Right Size for Your HVAC System

Older homes may lack the proper sizing system, so it is quite common to find furnaces that are more than twice the size required for this type of residence. Oversized equipment cycles too often, reducing its life and failing to deliver the same level of comfort and indoor air quality as a properly designed system.

Au contraire, the inside will be cooled continuously by an undersized system, which will cost a lot more in the long run. The HVAC system is programmed to switch on, heat, or cool to the desired temperature, and then shut down. When a system isn’t powerful enough to heat or cool the full square footage of a home, it merely circulates air and runs continuously to keep up.

Simply multiply the length by the width of the space or area to be cooled to get the size. Then multiply that total by 25 BTU to get a practical number. Whether it’s a wet, humid day or a hot, sunny, humid day, this allows for plenty of cooling or heating.


Another key aspect to consider when purchasing an HVAC system is its energy efficiency. The majority of the energy used in a home is used to heat and cool a room. As a result, your HVAC system’s energy efficiency can have a significant impact on your monthly energy expenses as well as your carbon footprint.

Furthermore, energy-efficient HVAC systems often last longer, resulting in considerable cost savings over time. Pay attention to the seasonal energy-efficiency rating of an HVAC system while determining its efficiency. High-efficiency systems can often save you 30% or more on heating and cooling bills!

Does HVAC Brand Matter?

Basically, yes. While most manufacturers aim to produce a high-quality product, name brands are important since big manufacturers select which contractors are allowed to sell their products. Smaller, less exclusive brands have less control over who installs their equipment.

Because the installer is primarily responsible for the quality of the finished HVAC system, a dealer who offers name-brand equipment and is subject to the manufacturer’s discipline is more likely to perform high-quality work.

Ask for IAQ Add-On For Your HVAC

Humidifiers and high-efficiency air filtration systems are frequent indoor air quality (IAQ) add-ons to HVAC systems. When installing a new system, most contractors will give you a discount on these extras. When you’re sitting at the kitchen table with the contractor, inquire about add-ons.

During the installation of your new system, you may be able to get exceptional deals on the best IAQ systems on the market.

General Air has the Best Contractors to Install Your New HVAC

The single most significant aspect determining the quality of your HVAC system purchase is selecting the correct dealer/contractor! When you buy a television or refrigerator, you unpack it, plug it in, and it starts working. This is not the case with an HVAC system which must be custom-designed, constructed, and installed for each property. A responsible, quality-oriented contractor will take the time to ensure that your system is installed correctly, using the appropriate procedures and supplementary components.

A good contractor will assess your complete system, including ductwork and indoor air quality, ask questions to establish your specific requirements, and provide recommendations that are best for you, your house, and your lifestyle.
