What Are the Components of a Residential HVAC System?

While the main parts of an HVAC system are the heating, ventilation and air conditioning units, most modern systems also include air filtration and a cleaning element. Within residential buildings, heating is usually done by a furnace or boiler which consists of a pipe system for the fluid providing the heat or duct work in case of forced air systems.

A home’s heating system may also be connected to the water system, so warm water for bathing can come from the same device that supplies fluid for the radiators. While a ventilation system can be either forced or natural, a forced ventilation system is helpful for air cleaning purposes. Natural ventilation is also more limited during the warm, humid months.

Your air conditioning system is basically the opposite of your heating system because it removes eat from the inside of the house. One of the big advantages of installing an integrated HVAC system is that you don’t have to buy as many machines, which saves a great deal of time on installation not to mention the increased efficiency and reduced energy bills. A good idea to is to combine the function of the air conditioner and the furnace. Not only are heat pumps capable of both heating and cooling, but they can also function without the need of a back-up system, if calibrated correctly. At Precision HVAC, we look for the most economical solution to household heating and cooling needs for our customers in Summit and Chatham. For this reason, we prefer integrated systems when replacing or upgrading an older furnace, especially if you are designing for a new house.

Heating and Cooling Systems to Suit Your Needs

In addition to residential heating and cooling systems, Precision HVAC also services and installs light commercial systems for businesses in towns such as Madison and Millburn. The main difference between commercial heating and cooling systems and residential ones is that industrial systems have to be larger and more powerful than ones used in single residences.

For instance, a single split system may not be practical for a high-rise office building. On the other hand, it may be just right for smaller businesses such as shops or restaurants or individual offices within buildings. At Precision HVAC, we know how challenging it can be to figure out the type of HVAC system that works best for a business or residence. For this reason, our specialists look at the running costs, space dimensions, climate insulation and energy regulations among other factors to determine the type of system that suits our customers throughout Springfield and Short Hills.

Packaged Units

The lighter commercial AC units (three to 10 tons) typically include a gas or electric air conditioner or heat pump or a combination of both. On the other hand, larger heavier units (12.5 to 25 tons) ordinarily have a horizontal downflow to cover large areas and to control airflow. Nevertheless, nearly all packaged units come with durable scroll compressors to ensure they work efficiently, although they still require routine maintenance. The components for these systems are housed within one unit, usually on a rooftop. Although they are generally more expensive to run than single split systems, they also take up less space.

Split Systems

Due to their affordability, split systems are one of the most popular HVAC choices for small commercial buildings. They are great for shops, small offices and restaurants because you can control the temperature in individual rooms using a control panel or thermostat. It's called a split system because the main components for the air conditioning unit are separated and installed in different places.

There are actually two types of split systems that we work with on a regular basis: single split (or a central system) and a mini-split (also known as a ‘ductless system’)

  • Single Split System
  • Usually, a single split system has an air conditioner to cool a refrigerant and a furnace evaporator coil, which converts the refrigerant and circulates air using a system of ducts. Its main advantages are that they are much cheaper than bigger central systems, and they are also self-contained. Basically, other units can still work even if one unit of a single split system malfunctions. On the other hand, they may take up extra space on your property since each indoor commercial AC unit requires installation of an outdoor unit.

  • Mini-Split System
  • The mini-split or ductless system is the smallest of all types and is usually intended for smaller spaces such as a large single room or a series of small rooms. They don’t need much wall space, and the compressor and heat exchanger unit can be located further away from the main building, making it more flexible. Because they’re perfect for residential use and they are easy to install, mini-split systems are the most common type of AC unit on the market. The disadvantage is that they can be more expensive to operate than central systems. They are, however, popular for retrofitting buildings because you don’t need to install any ducts.

Ground Source or Geothermal Heat Pumps

Because these systems concentrate existing heat instead of producing it, they are an efficient renewable source of energy. For this reason, they are popular both for residential and small commercial buildings throughout towns we service such as Livingston and Florham Park.

Because the temperature below the earth’s surface stays relatively constant all year long, it’s colder than the air above ground in the summer and warmer in the winter. A geothermal heat pump works by transporting the heat from underground storage to a commercial space in the winter and then extracts heat back into the ground during summertime. Essentially, the area beneath the earth’s surface absorbs heat during the summer and functions as a heat source in the winter.

Another benefit of geothermal pumps is that they can also supply hot water. Installation costs, however, can run high because this technology is relatively new. Nevertheless, as a renewable source of commercial heating and cooling, it has the potential to reduce your long-term energy costs while also helping the environment.

Differences Between Commercial and Residential Systems

While we already mentioned that size and operating power is the most obvious difference between commercial and residential HVAC systems, there are other important differences to keep in mind.


In addition to being larger, a commercial HVAC system is much more complex than a residential system that only serves a single-family dwelling. A commercial building may have numerous office spaces or departments, each with their own heating and cooling needs with multiple thermostats that control different areas.

One company might, for instance, manufacture products that must be kept at a certain temperature. Another company may regularly host large groups that require variable temperatures to keep everyone comfortable. Additionally, the amount of people in the building, whether its use is periodic or constant and the end use of the structure are all factors that contribute to the complexity of the HVAC systems we install for our clients in Maplewood and nearby communities.


A residential HVAC unit is usually kept out of the way of the occupants on the side of the house or in the backyard while still allowing for easy access and service. A commercial unit, however, is normally located on the roof of a building instead of at ground level for a number of reasons.

  • It cuts down on noise pollution and complaints from the building occupants because these units are normally much louder than residential ones.
  • It avoids taking up usable space since most of the space on a rooftop isn’t used.
  • It’s also great for maintenance due to easy access and not having to interrupt any building activities during repairs.
  • It also reduces the chances of vandalism or accidental damage from the large amount of foot traffic in a commercial building.


While the drainage system for a residential unit drains into a single pan that is located outside the residence, a commercial drainage system consists of many pipes and pans to handle the greater amount of condensation produced by a larger system. Proper drainage helps to ensure total evaporation and to keep the system from overflowing.

Manufacture and Installation

Because commercial and residential systems have distinct uses, it stands to reason that they are manufactured differently. Typically, residential units are built as standalone systems that are split between the indoors and the outdoors and cannot be modified or expanded. A homeowner will usually purchase an HVAC system based on whether it can accommodate the square footage, number of rooms and windows, and the number of occupants of the dwelling.

On the other hand, a commercial unit is customized to the structure it will support. Because commercial systems are modular, they can be changed or added to if a building's heating and cooling needs increase whereas the entire unit would have to be replaced in a residence. Instead of splitting components between the inside and the outside, commercial systems keep the components together outside of the building with the exception of the ducts and zone dampers. This also aids in maintenance and upgrades.

Maintenance Costs

While homeowners are responsible for basic maintenance of their HVAC systems such as changing air filters, Precision HVAC is always available to help our clients within Union, Essex and Morris Counties with any issues that require professional HVAC expertise.

At a minimum, an annual maintenance check by a professional is important to make sure that your residential HVAC system is working correctly. Commercial systems, however, are more complex, and therefore, the maintenance and repairs are more costly. In order to maintain energy efficiency, their repairs must be performed by an HVAC technician who has experience with that building’s systems.

Because units function differently, it is crucial to work with an HVAC technician who specializes in the systems you own. At Precision HVAC, our experienced technicians are well-equipped to install and maintain a broad range of commercial and residential HVAC systems.
