Whether it’s a hot summer or a chilly winter, we depend on our HVAC Hickory, NC systems to keep us comfortable all year! This, however, implies that the HVAC system will consume a lot of power throughout the year. The dwellings’ energy usage is over 55% for heating and cooling alone!

Running an air conditioning unit is indeed a substantial expenditure, so it’s critical to understand how the HVAC Hickory, NC system works & how to get the most out of it every season.

Understanding the system may be very valuable whether you are a homeowner trying to find out what is wrong with the HVAC unit or perhaps a new technician learning the basics.

What Is an HVAC System?

You’ve probably heard of air conditioning because it’s a widespread phrase, but you might not be aware of the abbreviation HVAC.

HVAC is an abbreviation for heating, ventilation, & air conditioning. In the summer, air conditioning could keep you cool & comfortable, while in the winter, your heater or heat pump may keep you warm and cozy.

Essential HVAC Components

An HVAC Hickory, NC system is made up of numerous interconnected pieces. Understanding the purpose & operation of key components might help you keep your device working properly.

So, let’s get started by looking at some of the fundamental components of the HVAC system:

1. Refrigerant

It is the operating fluid and maybe the most important component of the HVAC system. The refrigerant absorbs heat and circulates cool air around your home. In the winter, it gathers heat from the outside environment & ejects it into the residence when turned on in reverse. It is what circulates the heat.

R410A is the refrigerant utilized in contemporary versions. However, R134 hydrofluorocarbons (HFCs) are also widely utilized and are currently being phased out. Previously, R-22 & R-12 were utilized, but they were phased out due to concerns that they contributed to the greenhouse effect. Newer types do not contain chlorine and are deemed environmentally safe.

2. Evaporator Coils

These coils are housed within the indoor unit/evaporator. The refrigerant circulates the coils, absorbing heat from the interior air that passes over it. After the heat is turned off, cold air is allowed to circulate back into the home.

3. Compressor

It is an outside unit component that compresses the refrigerant, transforming it from a gaseous to something like a liquid condition. This process gets the refrigerant ready to exhaust the heat it picks up in the condenser.

4. Condenser

Because it is an exterior unit, it is in charge of dispersing absorbed heat outdoors throughout the cooling process. When the refrigerant reaches the condenser, the coils here help the refrigerant transmit heat energy to the outside air.

5. Ductwork

It pertains to the network of ducts used for air transportation. They distribute air from the HVAC system to each room in your home.

Ducts that are well-maintained and appropriately insulated are essential for an effective system. And this work can be done with the help of HVAC contractors in Hickory, NC. 

6. Vents

Air enters your home through vents as it moves through the ductwork. They are rectangular coverings that can be found on the wall, floor, or ceiling.

7. Blower Motor

When the air temperature reaches the temperature set by the thermostat, the blower motor activates. It circulates air around your home by pumping it.

How Does an HVAC System Work? 

In theory, an HVAC system moves heat from one section of the house to the outside atmosphere by using refrigerant. This is especially true during the summer. In the winter, the process is inverted, and heat from the outdoors is removed and transported within to provide heating.

The refrigerant is initially compressed in the outside unit’s compressor part. It has now become liquid. The refrigerant is also heated up during this process and must be cooled. This is done inside the HVAC system’s condenser or exterior part.

Fans cool the refrigerant by blowing it over the condenser coils. The refrigerant is then sent via an expansion valve that rapidly expands the refrigerant & converts it to a chilly gas. The gas is transferred through the evaporator through a sequence of coils, where it collects heat from the inside air. A fan circulates air from the chamber over the coils, cooling them.

The refrigerant, which has become hot due to heat absorption, is now fed through the compressor once again, & the cycle is repeated. To make the best use of your HVAC system, you can take the help of HVAC contractors in Hickory, NC. 

Types of HVAC Systems 

There are several HVAC system kinds, each having its own set of advantages and disadvantages. You may use a ductless mini-split if you live in a tiny apartment or a geothermal unit if you are building a new house and want to be green.

Let’s take a deeper look at each option:

1. Cooling and Heating Split Systems – Central

The most popular form of an air conditioner is a split system with separate inside and outdoor units. They are commonly utilized because of their high SEER rating & energy efficiency.

They deliver both warmth and cooling, as the name indicates. The split system’s outside unit consists of a condenser & a compressor. The indoor unit, also known as an evaporator, is installed indoors, commonly in a closet or basement. The 2 units are linked by a copper tube. The blower directs warm air towards the evaporator, where the heat exchanger coils absorb heat before delivering cold air to your home via ducts.

A split system may be simply installed by an HVAC service in Hickory, NC, with little to no adjustments to your home’s existing ductwork. If your property lacks ductwork, the installation procedure will be more expensive.

2. Hybrid Split Systems

These systems, as the name implies, the transition between electrical & gas power as needed. They work in the same way as a split system but consume less power due to their hybrid functioning.

When heat is required, the furnace activates and produces heat using a different fuel source, like natural gas or oil. This warms the air, which is subsequently channeled through the duct system by a blower fan.

When there is a need to chill, the air conditioning system kicks on and delivers cool air to various regions of the house. Furthermore, hybrid split units can help you save money on your energy costs in the long run by reducing energy use.

3. Ductless Mini-Splits

Because they do not require ductwork to cool and heat your house, ductless mini-splits are quickly becoming popular. Furthermore, the absence of ducts precludes the potential of duct-related power losses. The most recent versions combine heating and cooling in a single unit. They are a very efficient device that is ideal for tiny spaces.

Ductless mini-splits are made up of an interior unit that is unusually put on the wall & an outdoor unit that is either placed on the ground or linked to the wall. Both units are linked by a short pipe. The indoor unit functions similarly to the evaporator unit of such a central air conditioning system. It transports heat from the interior to the external compressor unit. In the winter, this procedure is reversed to heat the residence.

There are several varieties of mini-splits on the market, including wall-mounted mini-splits, multi-zone mini-splits, floor-mounted mini-splits, ceiling cassette mini-splits, & concealed duct mini-splits.

4. Packaged HVAC Systems

In these systems, the condenser, compressor, & evaporator are all bundled together. They are often maintained outside next to a wall or even in the attic.

A blower is used in packaged systems to blast cool/hot air into the home & pull untreated air into the unit. The ductwork circulates air from the air management unit into the house and distributes it back.

They use less energy than traditional air conditioners yet are ideal for houses with limited space.

5. Geothermal HVAC

Homeowners favor geothermal systems as they are more energy-efficient and environmentally friendly than typical HVAC systems. They also assist in minimising electrical system strain, particularly during peak summer hours.

Geothermal heating & cooling systems exchange heat with the earth to produce warmth and cooling. It distributes heat from the house to the ground during the summer and vice versa during the winter. It can do this by laying lengthy subterranean pipes packed with a cooling refrigerant. Furthermore, the loops are linked to a heat pump in the home, which serves as both a furnace & an air conditioner.

Difference Between HVAC and Air Conditioning 

An HVAC system is intended to suit your home’s heating and cooling needs. It also offers ventilation to keep the interior air quality high. A specialized heating unit, like a furnace, provides heating in an HVAC system. HVAC systems are meant to keep your home clean by removing pollutants, dust, and allergies.

AC, on the other hand, mostly refers to units that can only offer cooling and heating but not ventilation. Generally, air conditioning is exclusively used for cooling, although this is not the case. They may also heat the room when used in reverse. An air conditioning unit does not include a furnace or perhaps a ventilation system.

While all HVAC units provide air cooling, not all air conditioners provide specialized heating and ventilation facilities. HVAC service Hickory, NCprovides you with the best servicing & installation for your HVAC system.

What Is a Smart HVAC Unit?

Like any similar smart device, a smart HVAC unit may connect to the internet. This gives you a variety of settings & remote access to the air conditioner, which does not arrive with standard remote control.

By connecting the smartphone to smart HVAC equipment, you can use the AC from anywhere, at any time. You can even link the smart HVAC to a smart home system, such as Google Home and Amazon Alexa, & your air conditioner will function in tandem with all of your smart gadgets.

Smart air conditioners, on the other hand, are highly expensive. They can cost anything from $300 to $3,000 or more.

Benefits of Having a Smart HVAC Unit

However, if you still believe that your AC’s remote control provides sufficient setting choices and that a smart HVAC unit would provide additional benefits, let’s take a brief look at some of them.

  1. You can operate your air conditioner from any place in the world. Have you forgotten to switch it off before heading off to work? Have you gone food shopping & have pets at residence? Are your children sleeping at home while you’re away? Or did you go on vacation but were concerned about frozen pipes? All of these issues may be resolved since you can access the AC unit via an app.
  2. Instead of setting the temperature at a single set-point, you may use a smart controller to establish zones and manage the temperature of separate rooms based on individual needs.
  3. With summer approaching and temperatures rising by the day, have you already budgeted for air conditioning costs? You may save a lot of energy by using smart HVAC equipment. And, if you have a smart controller, you may save up to 25% on electricity.
  4. Your air conditioning unit’s efficiency will be greatly improved. It will switch on and off on its own before and after you arrive. You’ll never have to return home to a hot, humid atmosphere. It will always be kept on your favorite stings.
  5. Smart air conditioning equipment, which operates intelligently throughout the day, also assists in lowering your carbon impact.
