Do All HVACs Have Fresh Air Intake?

HVAC systems are a great way to maintain a comfortable indoor temperature all year round. However, the question is whether they have fresh air intake or they simply recirculate the same stale air over and over. This article takes a closer look into this issue so that you can gain a better understanding of these systems and of their mechanism of action.

To start with, if you have a split air conditioning system you should be aware of the fact that it doesn’t have any fresh air intake. The design of this system isn’t meant to allow bringing in the fresh air. This is why it is very important to clean these units on a regular basis, preferably at least once a year. Besides, you should replace their filters as often as needed, in order to avoid contamination with airborne germs and pollutants. On the other hand, split systems have the advantage of a lower price. Their installation is also easier. All these may compensate for a certain lack of fresh air intake. In addition, some may argue that hot, humid and polluted air from the outside could do more harm than good. These being said, it might be better for a HVAC system not to bring in the fresh air, as it would need to work harder to purify and cool down this air, hence increasing the operating costs.

There are some HVACs that provide fresh air intake. These systems are usually more complex. This fresh air intake is usually located on the ceiling, and it features filters that prevent dust and dirt from polluting indoor air. Such systems have a very smart functioning principle. They allow outside air to enter only in certain conditions of pressure and moisture difference between the air inside and the outdoor atmosphere. These systems are actually beneficial, as they help to maintain a safe atmosphere and constant temperature and humidity levels inside the building.

As a general rule, a percentage of 5% to 10% of fresh air is desirable. However, if your HVAC system doesn’t allow it, you’ll be fine without it, so you won’t have to replace it. Just make sure that you clean the filters and perform routine maintenance at regular intervals and you won’t have any problems. Also, keep in mind that a certain amount of uncontrolled and unfiltered air will enter your home anyway through various cracks and crevices. You won’t be able to seal your home completely, so you’ll always have this fresh air intake, whether you want it or not. In case you worry that your indoor air won’t supply you with enough oxygen, you can relax and forget about it. Your home isn’t a sealed container, so there will always be some air coming in through holes and cracks you don’t even know about.

If you want to know whether your HVAC system has fresh air intake, you can read the owner’s manual or contact the representative office of the manufacturer to ask for such details. You’ll have your answer right away.

Does My HVAC System Have Humidity Control?

Where would we be without our trusty HVAC systems? For most of us, we quite simply could not imagine life without them. However, from time to time we may have questions about our systems and how they actually operate. For instance, you may be wondering whether your HVAC system has humidity control. This isn’t as straight forward a question as it may initially seem, however, let’s take a look at how most HVAC systems operate and the effect this has on room humidity.

What Is A HVAC System Capable Of Doing When It Comes To Humidity?

HVAC systems are usually able to remove humidity from an indoor space. This is especially the case when the air conditioner is running.

How Have Engineers Designed HVAC Systems With Humidity in View?

Engineers tend to design HVAC systems to control temperatures. This is usually the main focus as opposed to a focus on removing moisture, however, the two are directly linked as we shall now see.

How Does A HVAC System Cool The Air?

To cool the air, the HVAC system needs to remove excess humidity. For the HVAC system to be able to carry out this task it needs to be efficient, often there are variable speed capacities which allow the system to have more time to remove humidity from the indoor space.

Why Is A More Efficient System Worthwhile In Controlling Humidity?

Systems which are more efficient can control the temperature in a more precise way. They will eliminate cold or hot swings which are noticeable and hence not allow humidity to build up in the air. In this way, we could say that such efficient systems do indeed control humidity.

What Are Other Benefits Of Choosing An Efficient System Which Can Control Humidity?

When the HVAC system that you have installed in your property, whether this is your home or place of work, is highly efficient it means that the air is constantly being conditioned. The direct result of this is an atmosphere where there is less chance of stagnant humid air. With less risk of such humdiity, there is less risk of mold in the walls, as well as in the attic.

Highly efficient systems also tend to run more quietly which can be a real plus when you are trying to sleep at night. In addition, many homeowners may find that their energy bills are lower thanks to an efficient HVAC system since the running of the system is generally more energy-efficient overall.

The Bottom Line On Whether HVAC Systems Have Humidity Control

Humidity can be a real challenge to cope with in any property. HVAC systems vary in both efficiency and quality, and this can affect how much of an issue humidity is in your home. By choosing a system which is efficient and of good quality it is possible to control the humidity in your indoor space and to ensure that everyone feels fresh, comfortable and ready to take on whatever happens to come their way.
