Common Types of HVAC

Based on our experience as the leading Irving HVAC service provider, know about the different types of HVAC (heating, ventilation, and air conditioning) systems. And we can tell you that each of them has its set of advantages and disadvantages. Some of the most common types include the following.

Common Types of HVAC

Central Air Conditioning:

This type of system is the most common in homes and buildings. It consists of a central unit, typically located in a basement or attic, that cools and dehumidifies the air, which is then distributed through a system of ducts. Central air conditioning is efficient and can cool a large area, but it requires ductwork to be installed, which can be costly.


  • Efficient cooling: Central air conditioning systems can cool large areas effectively and quickly.
  • Whole-house cooling: A central air conditioning system can cool the entire house, rather than just one room or area.
  • Better air quality: It can help to improve indoor air quality by removing pollutants and allergens from the air.
  • Low maintenance: Central air conditioning systems have relatively low maintenance and only require occasional service and filter changes.
  • Versatility: The system can be integrated with other systems such as furnaces or heat pumps to provide heating as well as cooling.


  • High installation costs: Installing central air conditioning can be costly, as it requires the installation of ductwork throughout the house.
  • Reduced energy efficiency: If the ductwork is not properly sealed and insulated, it can lead to leaks and drafts, which can decrease the system’s energy efficiency.
  • Noise: Central air conditioning units can be noisy and can be disruptive, particularly if they are located in a bedroom or living area.
  • Limited control: With central air conditioning, it is difficult to control the temperature in different rooms or zones within the house, as the temperature is controlled by a single thermostat.
  • Dependence on electricity: The system requires a significant amount of electricity to operate, which can be a problem during power outages.

Central air conditioning can be a great option for many homes, but it’s important to weigh the pros and cons before making a decision. It’s also important to consider the location, climate, and architectural layout of the building as well as your budget before deciding on a specific type of HVAC system. And you can contact our Irving HVAC team for professional advice.

Ductless Mini-Splits:

This type of system does not require ductwork and instead, consists of an outdoor unit that is connected to one or more indoor units, typically installed in individual rooms or zones. They are easy to install and are more energy-efficient than central air conditioning. It also provides greater control over the temperature in individual rooms and zones.

  • Improved air quality: Ductless mini-splits can help to improve indoor air quality by removing pollutants and allergens from the air.
  • Flexibility: They can be used for both heating and cooling, and can be easily installed in a variety of settings, including homes, apartments, and commercial buildings.


  • Higher upfront cost: Ductless mini-split systems can be more expensive than traditional window air conditioners.
  • Limited heating capacity: Ductless mini-splits may not provide enough heat for extremely cold climates or large areas.
  • Limited lifespan: They have a shorter lifespan than central air conditioners.
  • Limited control: Ductless mini-splits allow only limited control over temperature, as the system’s thermostat is usually controlled by the indoor unit.
  • Outdoor unit: Ductless mini-split systems require an outdoor unit, which can be unsightly and take up space.

Ductless mini-split systems are ideal for many homes, particularly for those looking for an energy-efficient and flexible HVAC system. However, it is important to consider your home size, budget, and location before deciding on a specific type of HVAC system. Proper sizing and professional installation are critical for the best performance of ductless mini-split systems. That’s where we come in. We can guide you in your choice of HVAC units and even install them for you. It starts with you contacting our Irving HVAC installation and maintenance team.

Geothermal Systems:

It uses the constant temperature of the earth as the exchange medium instead of outside air. And it utilizes a closed-loop system that circulates a water-based solution through buried underground pipes. They are highly energy efficient and can provide both heating and cooling, but they can be relatively costly to install, and the long-term savings on energy bills can be significant.


  • High energy efficiency: Geothermal systems are highly energy-efficient, as they take advantage of the constant temperature of the earth to heat and cool a building.
  • Low operating costs: They have low operating costs, as they require little energy to function.
  • Long lifespan: These systems have a longer lifespan than traditional HVAC systems, as they are less affected by weather conditions.
  • Fewer emissions: The units do not produce emissions, making them an environmentally friendly option.
  • Versatility: Geothermal systems can provide both heating and cooling, making them a versatile option.


  • High installation costs: Geothermal systems can be expensive to install, as they require the drilling of underground loops.
  • Limited by location: The units are limited by location, as they require certain geological conditions to function effectively.
  • Limited scalability: They may not be suitable for large commercial or industrial buildings.
  • Limited retrofit: Geothermal units are typically not suitable for retrofit, as the installation of underground loops can be difficult.
  • Limited maintenance options: Geothermal systems require professional maintenance and it may be difficult to find a qualified professional.

Geothermal systems are a highly efficient and environmentally friendly option for heating and cooling buildings, but they may not be suitable for everyone. It’s important to consider your location, budget, and building size before deciding on a specific type of HVAC system. It’s also important to note that geothermal systems work best in areas with moderate climate and suitable geology.

Boiler Systems:

They use hot water or steam to heat the building. It is commonly used in colder climates or older buildings with radiators. They can be fueled by oil, gas, or electricity. This type of system is efficient and reliable, but it may require regular maintenance and service to keep it running smoothly.


  • Reliability: Boiler systems are generally reliable and have a long lifespan.
