Did you know that Americans $14 billion on HVAC services each year?
An important question to ask is “how does an HVAC system work?” Doing so allows you to save money. After all, it allows you to understand how to better take care of it.
It also helps you get an idea of why certain issues arise.
Interested in knowing more? Keep reading to find out more about how an HVAC system works.
What Is an HVAC System?
An HVAC system refers to the equipment and process responsible for heating, ventilating, and cooling your space.
Split systems, heat pumps, packaged units, and ductless systems are four types of HVAC systems available. Split systems have an indoor and outdoor unit connected to a widespread ductwork system running through the house via air vents.
Meanwhile, heat pumps and packaged units are systems that use one unit. Ductless systems have centralized air systems controlled using thermostats.
How Does an HVAC System Work?
To understand how an HVAC system works, familiarize yourself with its primary components. It will help you understand what powers an HVAC system and more.
Heating: Major Components and How They Work Together
Let’s discuss how heating works on your property by identifying the heating equipment. The most important heating equipment of an is the furnace.
Furnaces come in different forms, which include propane, electric, oil, and geothermal furnaces. The most common is the natural gas furnace. As such, we’ll tackle how gas furnaces work.
To start, the gas or fuel valve powers the furnace since it gives the fuel burned to create heat. The heat exchanger then heats the cool air entering the system. Once the air passes through the heat exchanger, it circulates back into the house as warm air.
It’s the blower’s job to push the heated air into the ductwork. It passes through the air filter. It’s where the system removes the impurities that lower air quality.
Ventilation: Exhausts and Brings in Fresh Air
Ventilation handles bringing fresh air and removing contaminated indoor air. It also controls airborne contamination inside your property.
Poor ventilation results in low-quality indoor air quality and causes various health issues. It’s because dirt and bacteria linger inside your home, increasing the chances of inhaling them. It’s especially risky for people with asthma and allergies.
Proper duct installation helps achieve proper ventilation. Chimney flue and vents also count as ventilation systems. These exhaust ventilation systems depressurize and let in fresh air through vents in your property.
Air Conditioning: How Does It Keep Your House Cool?
To provide cold air inside an enclosed space, an air conditioning system is necessary. An air conditioner removes humidity and heat from indoor air using a four-step system.
The compressor in the air conditioning unit uses a motor. It pumps and converts liquid refrigerant into a high-pressure gas. It pumps the pressurized gas into the system to collect and transport heat.
After going through the system, the gas then passes through a condenser. It allows the gas to release the collected heat.
The system pushes the heat out into the exterior part of the air conditioning unit. The condenser then turns the gas back into liquid form. For more information on the condenser, check out https://www.schneidermechanical.com/what-does-a-condenser-do-the-ultimate-guide-to-condensers/.
Once the condenser finishes its part, the expansion valve comes in. It changes the pressure of the liquid refrigerant from high to low.
If you notice that your air conditioning unit is producing warm air, your expansion vent may be the issue. Get a professional to check and fix the issue. Otherwise, your air conditioning system will be less effective.
Evaporator Coil: Where Magic Happens
Magic happens inside the evaporator coil located above your AC unit. The evaporator passes the refrigerant into a coil. It’s where warm air blows over the refrigerant, causing the air to lose heat and humidity.
Other Components of HVAC System You Need to Know
There are several other parts of an HVAC system that help HVAC systems function. Some of these include the air return, which pulls in air through the filter and into the system.
Exhaust Outlets refer to components that help ventilate heat out of the house. If you don’t want stale air, ensure that these outlets remain functional.
Another important component of an HVAC system is the thermostats. It’s the brain of the system as it can sense and analyze the temperature.
The thermostat instructs the air conditioning unit or furnace when to start and stop. When the room reaches the ideal temperature, the thermostat turns the furnace or AC off. As soon as it increases or drops again, the cycle will start over.
Who Should You Call to Service Your HVAC System?
Installing or fixing an HVAC System requires skills acquired through experience and training. Although it may seem like simple work, making HVAC repairs is risky and complex.
Repairing your HVAC system on your own may make matters worse. You might end up cutting wires or installing incompatible parts. It results in more damage or destroys your HVAC system.
Thus, let an HVAC licensed professional handle HVAC installation, repairs, and part replacements. It eliminates the risk of further damaging your system.
When looking for an HVAC expert, inspect their background first. Check their online reviews to see whether they’re mostly positive. Read how they respond to customer concerns to determine their professionalism.
Otherwise, you might end up with a disreputable company. In most cases, they have no insurance to cover possible damages.
