HVAC Systems-All There Is To Know

HVAC stands for heating, ventilation and air conditioning. The function of an HVAC system is to provide heating and cooling to your home while also releasing moisture through the vents.

If you have decided to get a new HVAC system installed in your home, you have made the right decision. However, you need to be careful as they are significant investments. The last thing you want is to spend several thousand dollars only to find out the system isn’t suitable for your home.

Here are some important aspects of HVAC systems that you need to know before making a purchase:

Different Types of HVAC systems

The first thing you need to assess is the type of HVAC system that is suitable for your home. The two most commonly used HVAC systems in USA are splits systems and packaged systems.

The split systems come with a coil, a furnace and a condensing unit. However, you can only install a split system in your home if you have a crawlspace, an attic or a basement. Split systems are quite efficient as well as economical to run.

If you don’t have enough space in your attic or basement, then you go with a packaged system. It comes in a closet setting and is easier to install. The components of a packaged system include heat pumps, air-conditioner, evaporator, fan coil and thermostat.


The next most important consideration is the size of the HVAC unit. The size of an HVAC system is usually measured in BTUs (British Thermal Unit), with 12,000 BTUs representing 1 ton.

To determine how much BTU you need, you will have to calculate the square footage area of your home. Once you have that, multiply the square footage by 25 and add 400 for each person in your home. For each window, add another 1,000. The number that you end up with represents the BTUs that your HVAC needs to provide.

If you get an HVAC that is too small, your system won’t work efficiently and won’t be able to provide you with adequate cooling or heating.

SEER Rating

You mustn’t ignore the SEER (Seasonal Energy Efficiency Ratio) rating of the HVAC system as well. The SEER rating system is developed by the US government, which is why it is quite reliable.

The higher the rating of an HVAC system, the more energy efficient the system will be. Try and go for an HVAC system that has a SEER rating of 12 or higher.
