What is HVAC, and how do HVAC systems work?
With the advancement of modern technology, HVAC systems have become a crucial part of our day-to-day living. Whether it’s fighting off the summer heat or keeping out the winter chill, life without your HVAC systems would be highly uncomfortable—possibly unbearable! To help you gain a deeper understanding of this modern-day miracle, Big Sky Heating and Cooling Systems Inc. has created this reader-friendly article, showing you just what this machine is and how exactly all the different components work to keep your indoor space comfortable.
What is HVAC?
Before we get into the mechanics of the setup and what is residential HVAC let’s cover the basics first. The name of the system is an acronym of all the main functions that the products perform for homes and businesses, as well as in industrial settings. It stands for “heating, ventilation, and air conditioning”—a fun and clever way to refer to such a large and intricate system!
HVAC System: Components & Functions
Alright, the name was pretty simple, but what exactly makes up a typical HVAC system? Instead of typing in “What is HVAC” into your browser, scroll down as we explain each separate component and how they work in tandem to keep your indoors comfortable and safe all year long.
Here’s an in-depth look at how this happens!
Heating & How It Works
Non-negotiable during the frigid months, the heating of any HVAC system is an efficiently working boiler, heat pump, or furnace. When you step into your home and find it cozy or work without freezing your fingers off at your office, the heating is what’s keeping your interiors from feeling like a snow palace. The heater can be either solar, electrical, or gas-powered, using the ductwork to circulate warm air throughout any given property.
Air Conditioning & Its Mechanics
Conversely, an AC unit keeps your indoors cool and comfortable throughout the summer months. Whether it’s escaping the July heat when you step into your home or the long hours you spend at the mall with friends, none of that would be possible without the air conditioning extracting indoor heat and expelling it outdoors while also balancing out the moisture levels.
Ventilation and Its Workings
If you keep your windows tightly shut during humid seasons to preserve the cooling and have every nook and cranny of your property insulated to keep out the frosty winter air, then how does the air inside remain fresh? The ductwork throughout your house or business establishment constantly circulates fresh air, ensuring your comfort, safety, and health.
What Ties Your HVAC System Together?
So, these are the major components of your HVAC system, but is that all? Of course not! There are a few other—smaller yet integral—parts of your HVAC systems that work efficiently to help these products perform efficiently.
Let’s examine one by one all the other parts of your HVAC system!
The Thermostat: The Brains Of The Operations
Okay, so we explained that your HVAC system keeps you cool during summer and warm throughout the cold season, but how does it know to do that? The answer lies in the thermostat. Users can easily adjust it to their preferences, setting the temperatures low during heat waves and cranking up the heat during blizzards. Integrating your thermostat with your smart home systems even allows you to pre-program the temperatures depending on the time of day and your schedule.
Filters and Their Functions
An integral part of any efficiently working HVAC system, they filter out dust, allergens, and other contaminants from the air. These are what keep you from sneezing every time you enter a closed space and even prevent mold growth.
The Refrigerant Lines
Finally, the refrigerant lines are what enable the system to cool down as well as warm up your indoors throughout the year by absorbing heat during sunny seasons and releasing it during chilly months.
Your HVAC System: More Than Just Comfort!
While the most obvious function of an HVAC system is to regulate indoor temperatures, it is also the most basic. Over time, your heating and cooling systems have also evolved, expanding their roles in your day-to-day life.
Let’s go through a few purposes of your HVAC system you might not even know about!
Protecting your health
First off, your HVAC unit is a silent hero, constantly protecting you and your loved ones from falling sick or succumbing to allergies. HEPA filters trap pollutants such as pollen and even pet dander. These systems can also balance out humidity, preventing mold growth and making it easier to breathe.
Structural Safety
Though you might not think about it, if your HVAC doesn’t control the temperature, the mold growth can cause structural damage, costing you thousands of dollars in repairs. Some HVAC systems even come with carbon monoxide detectors, warning occupants if there is a gas leak within the structure.
Improving Energy Efficiency
Finally, another impactful role that these systems play is to control your monthly energy costs. The newer HVAC systems are designed in a way that they consume 20–30% less energy, meaning that you free up your budget by opting for upgrades. As previously mentioned, smart thermostats also play a vital role in lowering energy costs.
Conclusion
HVAC is a fun and fast way to refer to your heating and cooling systems and uses a variety of energy sources to keep your indoor space comfortable throughout the changing seasons. They are an inextricable part of modern-day living and are widely used in homes, at workplaces, schools, and even factories. From keeping air fresh to preventing asthma triggers, they offer comfort along with safety. We hope this article helped you expand your knowledge on these systems and gave you a deeper appreciation for them.
FAQs
1: What are the most common types of HVAC systems?
Split systems are by far the most common.
2: What is the most common issue with an HVAC?
Dirty filters block your vents and cause your systems to work overtime to reach the required temperature
3: Why is HVAC better than AC?
Because the heatpump uses less energy and adapts throughout the changing seasons.
4. How long does an HVAC system usually last?
With regular maintenance, an HVAC system can last between 15–20 years.
5. How often should HVAC filters be changed?
Typically every 1–3 months, depending on usage, pets, and indoor air quality needs.
