Heating, Ventilating, and Air Conditioning (HVAC) systems provide homes and office buildings with conditioned, clean air at stabilized temperatures. When an HVAC system goes out, it can be as complicated to repair as it is inconvenient.

Contractors and repair personnel make sure these systems are installed and work properly so that building occupants remain safe and comfortable. When an HVAC system needs some work, consumers should make sure they are getting the most from their servicers.

What features matter most?

Quiet operation

Most HVAC units run quietly so that they don't disturb people who are inside the building.

  • Sealed combustion chambers: Sealing the combustion chambers reduces noise coming from the furnace.
  • Compressor sound blankets: Sound blankets deaden the noise created by air conditioner compressors.
  • Outdoor units placed far from windows: Installing the compressor and other outdoor parts far from windows reduces noise that can disturb building occupants.

Energy efficiency

Both federal guidelines and individual design help HVAC units save energy.

  • Air conditioners must be built to federal standards: Air conditioners must have an efficiency rating of at least 13-SEER, which means that they provide a specific amount of air conditioning for each unit of energy used.
  • Saves on electric bills: The energy savings generally translate into lower electricity bills for users who run an HVAC system.
  • Environmentally friendly refrigerants: Many HVAC units offer environmentally friendly refrigerants that help reduce carbon footprints while conditioning air.

Constant temperature

HVAC units help keep temperatures indoors stable and consistent so that users feel more comfortable.

  • Temperatures in line with health and environmental recommendations: Most HVAC units keep rooms at constant temperatures in line with what is needed for optimal health and to protect the environment.
  • Adjustable ducts: Most HVAC systems allow users to adjust ducts to control temperature in different rooms.
  • Return air diffusion: The system is set up so as much air is circulated into the room as is circulated out, thus keeping temperature constant and air clean.

Compliance with safety standards

Federal and state governments both issue safety standards to ensure that HVAC equipment works correctly and safely.

  • Compliance with environmental safety standards: HVAC units must comply with environmental codes for energy efficiency, clean air and more.
  • Compliance with hazardous materials standards: HVAC units must generate heat in approved ways that don't release excessive toxins into the air or use hazardous materials.
  • Compliance with ventilation standards: HVAC units must provide appropriate ventilation to lower the risk of respiratory infections and complications.

Indoor/outdoor units

HVAC systems often contain both an indoor and outdoor unit for compressing and circulating air appropriately.

  • Outdoor compression units: Many HVAC units come with an outdoor compressor that can be placed at a distance from the building to eliminate noise and improve air quality.
  • Ducts and vents: Indoors, there are usually ducts and vents that allow air to circulate in and out of every room.
  • Temperature control unit: The thermostat is usually indoors and can be set to the desired temperature.

What are different types of HVAC contractors?

Commercial contractors

Commercial contractors help install and repair HVAC systems in commercial buildings. This type of contractor often has specialized knowledge of industry-specific health and safety issues and concerns.

Furnace repair specialists

Furnace repair specialists keep furnaces in good working order. They can do inspections as well as repairs.

HVAC installers

Installers have specific skill sets related to installing new systems in homes and offices. They may or may not also repair HVAC units.

Who's it for?

People with health problems

People with health problems, especially respiratory illnesses, may need to get an HVAC system installed in their homes. HVAC systems can help purify air, reduce the risk of respiratory infections and protect immune system health by regulating temperature.

Commercial building owners

Many commercial building owners have HVAC systems installed to keep workplace environments up to code and to ensure a pleasant environment for employees, clients and customers.


Landlords may install HVAC systems in rental units to attract tenants and allow renters to feel more comfortable with where they live. Many states require landlords to keep buildings heated to a specific temperature during cold months.


People who care about the environment may prefer to use an HVAC system as it is more energy efficient.
