We have seen only industry professionals and the wealthy ones use the term “HVAC” in the past. However, with time, there is an entire industry of HVACs out there which means that getting one is as simple as walking to the market and buying one.
HVAC has replaced air conditioners as a general type for cooling. However, HVAC is a lot more than that. Some questions pop up about HVAC, such as its specific use, and some even question what it is.
Well, you are in the right place! In this article, we will be talking about everything that there is to discuss HVACs. So let’s uncover HVAC together!
What is an HVAC System?
Let’s start by covering the basics first. HVAC is an abbreviation used for heating, ventilation, and air conditioning. It’s an efficient system that provides heating and cooling and is integrated mainly in residential and commercial buildings.
Whether a single-family home or a submarine, HVAC systems are used widely and can be found everywhere. HVAC systems are gaining popularity and becoming more efficient as new models are released. An HVAC system uses fresh air outdoors to provide quality indoor air quality.
When we talk about HVAC ventilation, it replaces or exchanges air within a space. The ventilation bit of HVAC helps the users achieve an idealistic environmental system, where the outdoor air is replaced with the indoor air. Ventilation provided by the HVAC system results in a better quality of air indoors and rids the environment of commonly known pollutants.
How Does an HVAC System Work?
Since most people mainly focus on indoor air quality and thermal comfort, you will find that all three main functions of HVAC are interrelated and best suited to offer comfort. We will discuss some of the main components of HVAC and explain what part they play in making the HVAC functional.
1. Air Return
The air return is the part of the HVAC system that counts as the starting point of the entire ventilation cycle. This component sucks in air, drawing it through the filter, after which it passes the air into the central system. Consider dusting your returns frequently as debris and dust can quickly form up on the filters.
The filter in the HVAC system counts as the second part o the air return through which the air is drawn. To keep your system healthy, it’s suggested that you change its filters regularly.
3. Exhaust Outlets
The exhaust outlets are another part of your system responsible for expelling the exhaust created by the heating system. They are an essential component when we talk about heating, so you must keep them in good condition.
You must check your chimney flue or vent stack once a year and if the conditions require, tune them too.
The duct is the HVAC part where the air, either heated or cooled, passes. Experts suggest that it’s best to get the ducts of an HVAC system cleaned every 2 to 5 years to ensure the durability and functionality of your system for a long time.
5. Electrical Elements
There are various electrical elements in your HVAC system, and dealing with them is often trickier. However, you must know that most HVAC problems will originate from here.
As soon as you feel that something is off, it’s best to check for a tripped breaker or ensure that your thermostat batteries haven’t died.
6. Outdoor Unit:
The outdoor unit makes up a considerable part of the HVAC system. The outdoor unit comes with an integrated fan that provides airflow. Debris and vegetation in the outdoor unit can land you in trouble if the fan stops working.
The compressor is one of the main components of the outdoor unit, and they are used for converting the refrigerant from a gas to liquid and sending the cooled air to the coils.
In most cases, if the ac stops working normally, the problem usually is the compressor. Failure of the compressor is one of the prominent reasons behind HVAC system failures, so it’s best to ensure that they are checked regularly.
The coil is another component of the outdoor unit, and it is mainly responsible for cooling the air passing through the HVAC with a bit of aid from the refrigerant. To keep your system in the best shape, it’s recommended that you check your coils annually. If they freeze up, the best idea would be to check your filters or refrigerant levels.
The blower is responsible for drawing in warm air through the main section of the HVAC. Regular maintenance of an HVAC system can ensure that the air moves through more efficiently and makes your system more durable.
Health Benefits of an HVAC
We have already established that HVACs are a step up over your traditional conditioners. However, according to Dr. HVAC, a considerable benefit of having an HVAC system in your house is its health benefits!
Some of them include:
1. Reduce High Humidity
The most significant advantage to having an HVAC system in your house is that it reduces the humidity of your house. You are likely to stay healthy when you live in a house that prevents high humidity. Furthermore, having less humidity will also make your house feel less damp.
When you ensure that your house is less damp and the humidity level is not too high, you can prevent your house from known issues, including dust mites, mold, heatstroke, and dehydration.
2. Reduce Asthma Attack
If you have asthma, getting an HVAC system for your home can be a great way of making your home a haven! Using an HVAC system to keep your house cool gives you a chance to avoid asthma attacks.
The HVAC system can block asthma attacks by filtering out dirty air that might contain dust mites, allergens, or pollutants. An HVAC system can also eliminate any dampness, further leading to mold.
However, even with the HVAC, there is a chance of getting an asthma attack. You must change the air filters regularly. If you do not change the air filter, you’re cycling dirt filtered by the HVAC back into your home.
Consider changing your air filters every 30 to 60 days. Changing air filters is a considerably easy process. However, if you want an expert to do it for you, look for HVAC companies near you. If you don’t know anything, the best idea is to go to the internet and search for it.
You can search for an HVAC company near you by going to Google and typing something like “HVAC companies in Toronto” if you live in Toronto. Beware when looking to hire an HVAC company and only go for those with good reviews and rank high on the list.
3. Better Air Quality
Installing an HVAC system can make breathing easier as air quality improves significantly. There are many pollutants in the indoor air, including dust to bacteria, that can result in a hazard to your health if not appropriately ventilated and due to excess heat. It is common for you to go through diseases such as coughs, colds, headaches, and fatigue.
Your HVAC system can filter out the impurities and hazards as it properly ventilates your house and manages the temperature of your house.
4. Reduce the Risk of Dehydration and Heatstroke
You might think dehydration only happens because of a lack of water, right? When you sweat, your body loses water, leaving you vulnerable to dehydration. The more sweat, the more water you lose from your body, leaving you vulnerable to dehydration. And when the temperature is higher, it’s easy to fall sick to diseases such as heat stroke and dehydration.
Installing an HVAC can manage your house’s temperature and ensure that your house is safe from such diseases. The cool air circulated by the HVAC will lower the temperature of the entire house, which will cause you to sweat less, and your body temperature will remain low too.
5. Stop insects and parasites
The neverending insects and parasites exasperate most of us, and it’s safe to say that you may have already tried a handful of the solution to rid your house of them.
Now, you may not know this, but having an HVAC can work wonders in this regard! Having an HVAC system lowers the temperature, which is not ideal for these creatures, so they are forced to leave. HVAC will also ensure that your body temperature stays low, ensuring that insects such as mosquitoes stay away from you.
At this point, you must be aware of the differences between the HVAC and the air conditioners. There is no real difference between either of them. Consider Air conditioners to be a subsection of HVACs as they focus on more than just cooling the air.
We have also discussed some critical components that make an HVAC system. Our experts have also offered insights into prolonging each part of the HVAC. Keep in mind that regular maintenance of the HVAC system is necessary if you want to ensure that they last you for a good long time.
