The Big Idea Behind HVAC System Design

So often, we get used to thinking about a home, store, office building, or any other structure as its component parts. For instance, when you head out to do some shopping, you see the open space that houses cash registers and products. You may know, in a distant sort of way, that there are also offices and storage/warehouse space that help support the business’s operations, but since they’re out of sight, they’re out of mind. As a homeowner or business owner, however, it’s important to think about your home/building as a whole, not just a collection of connected spaces, when you’re thinking about basic operational needs. 

The idea behind the best HVAC system design is that your space is treated as a whole, not just component parts. In doing so, your local HVAC technicians can set up a system that provides ample heating and cooling throughout your home or business without sending your utility costs through the roof. The overarching idea is that, by looking at the structure as a whole as well as the component parts, it is easier to make a more efficient and effective HVAC system.

Big Benefits to Comprehensive HVAC System Design

It’s commonly thought that HVAC system design is restricted to businesses and commercial properties, but it certainly doesn’t have to be. The benefits are the same whether applied to a full shopping mall or a single-family home — and the benefits aren’t limited to just the enjoyment of a higher efficiency system! Here’s why we recommend and provide custom HVAC system design:

Improved Comfort

The biggest benefit of HVAC system design is that you’ll be able to trust that spaces are heating and cooling appropriately — meaning no awkward super-cold patches in your office, or rooms of your house that are positively sweltering all summer. HVAC system design helps ensure that each room or space is set up with the right combination of insulation, ductwork, air returns, and registers to bring the room to the desired temperature and keep it there. With an HVAC system designed purposefully for your space, the ambient temperature can stay where you want it throughout each room or portioned-off space. 

This can include elements like additional insulation and the purposeful dispersal of vents to make sure the heated and cooled air ends up where it’s most needed. For example, in a multi-story home, you may not need to be able to pump as much warm air into the upper level because heat rises. However, you’ll still want plenty of cool air to move through the house during warmer months. HVAC system design takes these factors into account during design and installation. The result is improved comfort for everyone because the air is more evenly distributed throughout, rather than collecting in uneven patches, and it’s distributed in a way that makes sense for the season and the structure. HVAC system design is an ideal way to enjoy better comfort throughout the entirety of your home or commercial property. 

More Efficient Airflow

One of the most common reasons an air conditioner or heater doesn’t work as well as they should is not because they need maintenance. While regular HVAC maintenance is important for the ongoing health of your furnace and air conditioner, that maintenance isn’t necessarily going to have a huge impact on overall function unless the technician finds damage that needs to be repaired. If you want more efficient airflow (and you do), the answer doesn’t lie in maintenance alone; you need HVAC system design first to provide that efficient airflow, which can then be upheld over time with HVAC maintenance. 

The big reason we place so much value on a more efficient airflow is not only for better temperature comfort, but also because it means your HVAC system won’t have to work as hard to maintain a comfortable temperature. With the proper set up of insulation, ductwork, and HVAC equipment, it takes your system a lot less effort to get a space appropriately cool or warm. It also takes a well-designed system less energy to maintain that temperature. 

Reduced Environmental Impact

Heating and cooling options have come a long way over the years, but they do still have some impact on the environment, however small. Investing in HVAC system design is a great way to further reduce the environmental impact of your home’s or business’s heating and cooling needs. The big reason a custom system that has gone through the HVAC system design process is because of the improved efficiency, as we’ve already talked about. A more efficient system uses up less fuel and requires less electricity to operate because it can maintain the ambient temperature without kicking on as often or staying on as long. In addition to that, though, there’s the ongoing fact that a more efficient system will last longer and need less work done. 

Better Return on Investment

Getting full HVAC system design work and installation done is going to cost more than your typical furnace or air conditioner installation. But it’s well worth that upfront cost because of the return you’ll be able to enjoy for years to come. As we’ve already touched on briefly, HVAC system design helps make the whole system more efficient. First of all, this means you’ll spend less on utility costs because the system will need less electricity and less fuel than a non-efficient system. In addition to that, a more efficient system means there will be less strain on the system over all. Assuming you keep up with regular HVAC maintenance, the efficiency will mean there is less strain on your system, which cuts down on damage that will call for costly repairs down the road. And then, because your system doesn’t have to work as hard to provide appropriate temperatures, you can reasonably expect all of your HVAC equipment to last longer — sometimes to a magnitude of years longer than a non-efficient system.

Then, as if that wasn’t enough of a return on your initial investment, there’s also the appraisal value and resale benefits to consider. No, we don’t mean re-selling the HVAC system itself. Instead, we’re talking about the value a good HVAC system design can have for your home, business, or commercial building. It can add more to the appraisal value of your property, and can also help boost resale value when you eventually choose to sell. 

Cleaner Air

For many businesses and homes with a resident who has respiratory concerns, air quality is a big concern. The good news is that HVAC system design can take this into account from the start, making it much simpler to get a system that removes contaminants and provides cleaner air. First of all, purposeful HVAC system design means you can add in air purification technology to one space, multiple rooms, or simply bolster the air filtering for the system as a whole. In addition, the efficiency of the ductwork often means that there are fewer opportunities for dust, pet dander, outdoor air pollution, and other airborne contaminants to filter into your HVAC system. 

HVAC system design is also a good way to protect your home. A big element that many homeowners and business owners forget to consider is the damage done by humidity, mold, and fungi — something that is a pretty prevalent concern here in New Jersey. Most HVAC systems have some level of humidity control, but HVAC system design ensures that your system will offer the right amount of drying or moisturizing effects based on the local climate. For commercial properties that see higher levels of activity, especially gyms, your HVAC system can even help account for humidity added to the air via perspiration and similar causes (especially for gyms, yoga studios, and so on).

Increased Control

In some instances, especially multi-home properties and commercial buildings, it’s important to be able to segment an HVAC system and provide independent controls. Think, for example, of an apartment complex. Each unit will want to have total control over their home’s ambient temperature, which can be hard to do if someone in an upper unit wants it cooler, but the unit below them keeps their rooms roasting hot. A purposeful HVAC system design takes factors like that into account and helps give increased control to each segment of a property. Even in a residential home, HVAC system design can give you greater flexibility to control temperatures in different rooms or “zones” in your home. 

Overall, the idea behind HVAC system design is to make sure your heating and cooling needs are met with the best level of energy efficiency, cost effectiveness, and flexibility that your property needs.
