Knowing the components of the HVAC system will enable you to maintain it. Being knowledgeable about your heater & air conditioner can make troubleshooting simpler. By doing this, you can keep your system operating at its best and avoid expensive and inconvenient malfunctions. So, before you opt for an AC repair Hickory, NC, here are some major HVAC parts you need to know about!
When your thermostat starts your furnace & the heat from combustion rises, your heat exchanger absorbs heat & warms chilly air. Heat exchangers are a feature of all furnaces, even electric ones. To prevent cracks & other damage, this crucial component is made of sturdy stainless steel with air temperature alloys. Additionally, certain models also include a specific duct. This duct allows cool air to reach your heat exchanger more quickly & get you comfortable.
A carbon monoxide leak from your heat exchanger could result in nausea, headaches, or even death. If you have a wood or gas furnace, you should put detectors in your kitchen & bedrooms because carbon monoxide has no color and no smell. Additionally, you should have a professional check out your HVAC system’s components for issues at least once a year.

When the air in your heat exchanger gets hot, an electric blower motor drives a fan. This fan pushes the heated air through your home’s ductwork, air registers, & into all the rooms. All the heated air in your heat exchanger and ductwork will reach the rooms in your home before the blower motor stops to wait for the next heating cycle.
A blower motor with a variable speed setting may operate at various rates, allowing you to regulate the airflow in your house precisely. It can keep an eye on your HVAC system & fix a lot of issues. Variable-speed blower motors are less noisy. Moreover, it can reduce humidity more effectively in the summer because they increase to full speed. Furthermore, homes also save energy. That’s because they oft attain the optimal temperature before variable frequency appliances do. Get your blower motor checked by air conditioner repair Hickory, NC.
Your furnace supplies air to the fuel inside a combustor because oxygen must be present for proper combustion. When a tiny amount of an air & gas combination enters the combustor, the heating process starts. The mixture is then lit by a pilot light, which causes a controlled fire to burn as more gas & air are introduced into the burner.
A pilot light is nothing more than a tiny tube that emits a minute amount of gas to serve as a flame’s fuel. A glow stick is an electrical igniting mechanism. While pilot lights must be relit if they burn out, glow sticks light evermore. Pilot lights are only found in older furnaces since they consume more gas than glow sticks. Additionally, if they burn out, they may produce carbon monoxide, posing a safety risk.
Many high-efficiency gas furnaces contain an additional combustion chamber. Here carbon monoxide & unburned fuel are captured, compressed, and then ignited again. In this manner, you can use all the energy in natural gas & other fuels. Additionally, some systems feature integrated circuit boards. When a problem arises, it watches over your furnace and turns on light-emitting diodes (LEDs).

Condenser Coil or Compressor
Your air conditioner’s condenser coil or compressor, a component of your heat pump, is often positioned outside your house. A condenser disperses heat into the outside air to cool your house. This occurs when the refrigerant is compressed and condensed from a warmer gas to a liquid. To scatter the heat & accelerate the cooling of the refrigerant, the air is blasted over the compressor at the same time. The liquid refrigerant is then delivered to an evaporator coil by the HVAC system through a line or tube made of aluminum or copper.
Keep leaves, dirt, grass clippings, dirt, and other waste away from the condenser to conserve energy and avoid issues with your HVAC system. Please turn off the power to the outside unit once a year and give it a thorough cleaning with a garden hose. For optimal ventilation, a few feet of space should be left open on both sides. You should add a canopy for more shade and security for your unit.
If your AC compressor is not working, contact Air Conditioning Hickory, NC.
The evaporator coil, which is located inside the indoor air handler of your system, is a crucial component of any ac or heat pump. Your HVAC system pumps refrigerant to expansion valves. It then showers the liquid refrigerant to speed up its gas conversion. This absorbs heat & causes your home’s temperature to drop.
The fan in your HVAC system circulates cool air via your ductwork & into the interiors of your house. It does so after blowing warm air from your house through return ducts & over the evaporator to chill it. Your system then restarts the cooling cycle by returning the refrigerant gas to your condenser coil. Condensation occurs when heated air comes into contact with a cool evaporator coil. As a result, your home’s humidity level drops, the air inside feels cooler, and you can conserve energy throughout the summer.
The components of heat pumps and air conditioners are identical. In the winter, they can flip the heat transfer process, drawing heat from the outside air into your house and pushing out the cold. Your skin, eyes & nose can become irritated, and your air can dry when you use heat. To improve the comfort of your house and avoid these issues, use a humidifier.
Your evaporator’s condensation can promote mould growth, and moist coils accumulate dirt and dust. Even at the peak of summer, a refrigerant line leak can cause ice to form on the evaporator coil. These issues reduce heat transfer effectiveness, degrade air quality, and may harm your HVAC system. Enough ice buildup or mold development may impede airflow in your system. This leads to an expensive and uncomfortable breakdown. Get your AC repaired via Air Conditioning Repair Hickory, NC.
Many articles will not likely mention the duct system on a list of HVAC components. Ducts may be quite old and even predate the HVAC system that is now in use. They shouldn’t be disregarded as they circulate air throughout your structure. This makes them a crucial component of system function.
Your ductwork needs to be clean and undamaged for most of your HVAC system to function. AC repair Hickory, NC, is here to assist you with clean ductwork.
Older buildings may have narrow ducts susceptible to clogging since they don’t meet modern HVAC regulations. You can help increase the life span of other components by cleaning the ducts once a year. Remember to clean or change filters as directed by the manufacturer for the filter you are using.
A thermostat features controls for users and thermal sensors that determine when your heater & ac will turn on and off. It has specialized wiring that links it to your system. The optimal location for a thermostat is close to the middle of your house, away from draughts or stuffy spots. Some heating and cooling systems feature many thermostats, each regulating a distinct zone. In this manner, you may conserve energy by only cooling or heating inhabited rooms. Moreover, every member of your home can pick the temperature that they find most comfortable.
You may program your thermostat to change the temperature based on your route using a programmable or setback thermostat. You might save time, money & energy by doing this. Well, some devices can vary the temperature plan every day. On the other hand, some can establish distinct schedules for weekdays & weekends.
In the winter, lower the temperature setting on your thermostat; in the summer, raise it. Set your programmed thermostat to return your house to a comfortable temperature around 30 minutes before you return. That way, the air inside would have time to warm up or cool down. Many programmable thermostats can be controlled using a computer or smartphone. Other devices can track the humidity in your house & even learn your preferred temperature range.

HVAC System Types
HVAC systems come in four main categories and various sizes. They are:
- Split HVAC systems
- Hybrid Heat Split HVAC systems
- Duct-free or Ductless HVAC systems
- Packaged heating and air HVAC systems.
SPLIT HVAC SYSTEMS:
The most popular and traditional type of HVAC system, a split HVAC system, offers energy efficiency at a reduced price. In this approach, the system is divided into two major units for heating and cooling. Components are housed both outside and inside the structure. Split HVAC system installation is quite difficult. Air Conditioning Hickory, NC, is the best stop to get your AC unit serviced. Therefore, it must be carried out under expert guidance. A split HVAC system includes:
- An exterior component, often known as a condenser, including a heat pump or air conditioner
- A furnace that converts refrigerant and aids in air circulation, together with an evaporator coil, is part of an interior component
- A network of ducts that distribute the building’s air from the HVAC system
- A thermostat to control the system, either programmable or not
- Accessories that enhance the comfort and quality of the air inside the home, such as purifiers, UV lights, air cleaners, and humidifiers
HYBRID HEAT SPLIT HVAC SYSTEMS:
HVAC systems with hybrid heat are a more advanced type of split system with higher energy efficiency & lower utility costs. This type of HVAC system consists of
- Furnaces and an evaporator coil that converts refrigerant & circulates air
- 2. A heat pump that uses refrigerant to cool or heat it
- 3-A gas or oil furnace
- Ducts transfer hot or cold air throughout the structure
- 5. Add-ons that enhance indoor air quality
DUCT-FREE OR DUCTLESS HVAC SYSTEMS:
A ductless HVAC system is an effective HVAC system with high initial costs. For some needs & applications, it offers significant advantages over traditional duct systems.
The following components make up ductless or ductless-free HVAC systems:
- An ac or heat pump to heat or cool refrigerant
- Tubes and wires to connect the outside unit’s refrigerant to the fan coil
- A little fan coil
