What Do HVAC Systems Do?

HVAC is short form for heating, ventilating, and air conditioning. It includes air conditioners or systems that allow you to experience indoor comfort. It also allows you to thermal control your space.

They include the cooling and heating systems you may have in your home. Have you seen the large air conditioner boxes on top of office complexes or apartment blocks? These are essential, visible parts of the HVAC system.

HVAC has become very popular in homes and commercial properties. It handles the movement of air between the inside and outside of your workplace and home. It allows you to stay comfortable by regulating the air to your desired temperatures. HVAC technology ensures that the heating and cooling of air in your space is to your needs.

For instance, during the summer, it keeps your air fresh. In the winter, it allows you to have warm temperature in your home. Additionally, it handles reduction humidity indoors and filtering the air. HVAC is one of those systems you use in your home but never stop to think about until it requires maintenance.

How HVAC Works?

If you’ve visited an old house before, then you must have experienced the ventilation it’s prone to. In the past, most old homes had no ventilation systems. They allowed air to come in through gaps and cracks.

Unfortunately, older homes become airtight with time. This is why all homes should have the proper ventilation to allow fresh air to come in. It is crucial to have systems in place that will help you to get rid of carbon dioxide, bad smells, and moisture.

A good system will do all this. It will also help you to deliver fresh air into your home. When you introduce air into your system, it will filter it. It will also remove all the dirt, allergens, and excess humidity.

From here, your air conditioning can cool the air, or your heater can warm it up then send it around your home.

If you’ve got central heating and air system, the air moves throughout your home using tubes and pipes. A window system blasts air into your room. The result of using both approaches is clean, filtered air.

The HVAC system working principle regulates the movement of air. This movement of air is between the outside and inside of your home or workplace. There are different advantages and disadvantages of an HVAC system. Before we dig into the disadvantages of HVAC, let’s first learn what benefits the technology has to offer.

The benefits of HVAC

benefits of HVAC

* Improving Your Indoor Air Quality

The quality of indoor air isn’t as good as the outdoor air. Also, the the flow of air inside a home is usually congested. Inadequate airflow and congestion can cause pollution in your home.

This may cause colds or trigger allergies in some people. Using an HVAC system in your home helps you improve air quality. The system introduces fresh air and filtering dirt and allergens from your air.

* Conservation of Energy

Buying an HVAC system can be costly the first time as compared to purchasing a gas furnace. But, an HVAC system has some long term benefits that you shouldn’t ignore. It comes with both cooling and heating within the same unit.

This aspect saves you a lot on construction fees, power usage, and construction space. The HVAC system has a non-chlorine based coolant. This is excellent for energy conversation.

* Ensures Consistency in Moisture

Your home will always have some moisture in it. It doesn’t matter if you live in an unpredictable climate, or an area where you know how the weather will be. The air inside the home does not circulate well.

Thus, it may be subject to retaining a lot of moisture that may result in mildew or mold on the walls or under the floors. The growth of mold can result in various health issues and damage to the structure of your home. To reduce chances of damage, your HVAC system will move air between the inside and outside of your home.

Doing this guarantees you fresh, cool, dry air that’s more suitable for your home.

What Are The Limitations Of HVAC Systems?

The Limitations of HVAC System

HVAC technology comes in different forms. Some have furnace combinations and gas heaters that use energy pumps. The performance and quality of HVAC systems is varying. They have to stick to the advisable guidelines.

This is essential to ensure that they perform well. HVAC systems are great for making our lives comfortable. But, they also have some disadvantages. You must know the cons of an HVAC system before installing them into your home. Here are some of them.

> They Are Costly To Maintain

Your HVAC system needs regular maintenance to keep it working in tip-top condition. You will have to change the filter often to keep the air clean and check the belts. To do all this, you will need to enlist the services of a professional.
An HVAC system is usually in regular use. So, the maintenance required includes more work than some of your residential systems. They are very complex and will need more effort to maintain.

> They Are Expensive To Install

Even though in the long run, you may save a lot of money by installing an HVAC system, the initial upfront fee isn’t cheap. If your home has many rooms, you will have to ensure that the level of comfort matches every room. To achieve this, you need to install an indoor terminal system into each room. The process of installation can be draining, especially if you aren’t prepared for the high costs.

> Ventilation Air

The HVAC systems come with a couple of disadvantages. Ventilation air is one of them. If you have a central system, it introduces outside air and then distributes it all over the home. Without ducts, this isn’t possible.

> Central Unit Add-Ons

Ductless systems have a lot of limitations. Your technician can add many features to a cooling system or a central heating system. These include dehumidifiers, air purifying systems, and dehumidifiers.
One cannot install all these features with a ductless system. The reason is that there are no pipes to send airflow around the home.

> Renovations Are Hard

If you’ve installed a ducted system into your home, it may not be possible to do extensive renovations. The pipes are usually installed into the house walls, so bringing down walls may be risky.



HVAC systems are useful for maintaining comfort in our homes. Before installing one system, know “what are the limitations of HVAC” and how you can plan to get around them. Even with the limitations, it is an excellent system to have in the home to ensure your comfort. If you install an HVAC system , remember to only get a skilled and professional technician to do the maintenance for you. Anyone else can cause major damage to your system.
