An HVAC System’s 6 Most Critical Components

Knowing the ins and outs of your heating and cooling equipment can help you prevent expensive breakdowns and unwanted repairs while keeping the system performing at an optimal level. 

Fixing a mechanical issue is not easy, especially when you don’t know how the equipment works. When it comes to HVAC maintenance, however, it’s important to understand the role each piece of equipment plays. Air conditioning (AC) and heating systems are engineered with several moving parts, and this blog will show you the purpose each one serves.

The Most Important Parts of Your HVAC System

If you take the time to really examine your heating and cooling system, you’ll notice six particular components: 

  • Heat Exchangers 
  • Blower Motors
  • Combustion Chambers 
  • Condenser Systems
  • Evaporator Coils
  • Thermostat

These mechanical parts are more than just pieces of equipment; they are essential to greater indoor comfort, safer air quality, more cost savings, and long-term peace of mind. Here’s what you need to know about each element: 

Heat Exchangers

The heat exchanger houses the furnace. It not only absorbs heat from the outside, but it also masks cold indoor environments with warm temperatures. Every furnace is equipped with a heat exchanger, and it must be protected with layers of stainless steel and temperature-resistant alloys. Damage to your heat exchanger can lead to carbon monoxide leaks, which can be poisonous and even fatal. Make sure to have this piece of equipment professionally inspected at least once a year.

Blower Motors 

Once the heat exchanger presents the right temperature, the blower motor activates. Blower motors move warm air through the duct system before it enters the air handling vents. This sets up warm air to be appropriately distributed throughout each room. Blower motors do not produce any mechanical sounds, despite running at high speeds. They do, however, help keep humidity at an appropriate level. 

Combustion Chambers

The combustion chamber is the most important part of your furnace. Its purpose is to trap an appropriate amount of heat in the furnace. Combustion chambers work like a science experiment in which a mixture of air and other gases are combined, resulting in the beginning of the heating cycle. This component also captures carbon monoxide and compresses it into a safe, natural gas, allowing you to get every bit of energy from each fuel source. 

Condensing System (Compressor)

HVAC condenser coils can be found in all air conditioning and heat pump systems. Their purpose is to cool the building by releasing heat into the outdoor air. This occurs when a refrigerant is compressed into a cool gas that is released in the fan blower. Inspect your condenser on a regular basis and make sure it is free of any leaves, grass clippings, dirt, or other debris. Additionally, you’ll want to protect it by letting the unit rest in the shade. This helps mitigate the risk of overheating.

Evaporator Coils

Evaporator coils are essential elements in any air conditioning system or heat pump. Commonly referred to as the evaporator core, these coils help absorb heat the refrigerant generates. They are often located inside the air handler right below the blower fan. And while this mechanical part helps your AC system lower the building temperature, it also helps bring heat indoors when the temperature starts to drop. Be sure to perform maintenance on your evaporator core at least twice a year to prevent condensation. Otherwise, it may start to breed mold and cause significant damage to the rest of your HVAC system.

Thermostat

Thermostats are usually centrally located in your home or office building. These temperature sensors are connected directly to your HVAC system through a special set of wires. Some heating and cooling systems are equipped with multiple thermostats for different zones of the building. For maximum energy efficiency, it would be in your best interest to invest in a programmable thermostat. With this solution, building owners and facility managers can easily control different temperatures and humidity levels straight from their computers, smartphones, or tablets.

    I like that you mentioned that all the mechanical parts are essential to comfort and good air quality. I’ve been considering trying to install my own ac but with all these different parts it might be difficult to keep track of. Maybe I should reach out for air conditioning installation services to make sure it’s done right to avoid any problems.

    You made a great point that there are several components like the condensing system that can be very important to maintain in your unit. I’ve been wanting to make sure my systems in my home are running as efficiently as possible. Maybe I should get in touch with a residential air conditioning contractor and see how they can make all the parts function well.

    With my HVAC system, it’s imperative that all the parts work perfectly together. I do think that the blower motor has been giving me some trouble as even on high, it blows very softly. I might see about getting that component replaced since it’s not working as it should.
