Efficient, energy-friendly heating and cooling systems can cut costs and maintain the perfect temperature inside your home. Heating, ventilating and air conditioning (HVAC) systems provide homes and office buildings with temperature controlled, clean air. For people who don’t want or need an entire HVAC system, individual heating, cooling and air quality units are available to increase the air quality and comfort in your home or business. There are many factors that set one heating or cooling brand apart from another, such as price, size, efficiency and more.

If you own a home or business, you might need to purchase or replace your current HVAC system or individual units. You can make these purchases from a distributor or contractor. When an HVAC system or individual unit needs maintenance or repair, you might contact the distributor or contractor who installed it, or call a company that specializes in repair.

What features should you look for in a heating and cooling system?

Is the unit quiet during operation?

Most new HVAC units run quietly so they don't disturb people who are inside the building. Some window unit air conditioners and space heaters are noisier. It's best if you can see a demonstration of a unit before purchasing, to determine how quiet or loud it is.

  • Sealed combustion chambers: Heaters and furnaces either have an open or sealed combustion chamber where the actual burners are located. Sealing the combustion chambers reduces noise coming from the furnace, so if you’re looking for a quiet furnace, be sure the combustion chambers are sealed.
  • Compressor sound blankets: Sound blankets insulate an HVAC system or air conditioner by absorbing sound waves. Many units come with sound blankets, and they can also be added to noisy units to 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. Talk to your installer about your options.

Is the unit energy-efficient?

Energy efficiency refers to whether a unit’s output makes good, efficient use of the electricity or other power source it needs to operate. Both federal guidelines and individual design help HVAC units, air conditioners and heaters save energy.

  • High Energy Efficiency Ratio: Heating and air conditioning units are required to include information on their Energy Efficiency Ratio (EER). This is a ratio of the systems output (measured in British thermal units, or BTUs) to the energy input it needs to operate (measured in watts). This ratio tells you how efficiently the system uses energy; the higher the number, the more efficient the unit.
  • Built to federal standards: Since air conditioners are one of the worst environmental offenders, federal guidelines in the United States require air conditioners to have an efficiency rating of at least 13-SEER. This means they provide a specific amount of air conditioning for each unit of energy used. For a more efficient and cost effective machine, look for an even higher SEER rating.
  • Financial savings: Not only will having an efficient machine use less energy and meet federal and local guidelines, but energy efficiency also means a cost savings to you. The energy savings generally translate into lower electricity bills, plus some states offer tax rebates for people who purchase new energy efficient systems and household appliances.

Does the unit hold a constant temperature?

HVAC units, air conditioners and heaters help keep indoor temperatures stable and consistent so users feel more comfortable. But some units can hold a consistent temperature, while others create fluctuating temperatures in your home or office.

  • Heating and cooling capacity: Most HVAC units are designed to keep rooms at constant temperatures for optimal comfort. However, even if it is brand new and working properly, whether or not an HVAC system, heater or air conditioner can actually maintain that temperature depends on the temperature and humidity in your region. In very hot regions, you will need an HVAC or air conditioner with a high “tonnage” (a measure of air conditioning capacity). Space heaters and other types of room heaters may also be less effective in severely cold regions, and you may need to purchase more than one per room. Be careful to never plug more than one heater into the same outlet, which can overload the outlet and cause a fire.
  • Adjustable ducts: Most HVAC systems allow users to adjust ducts to control temperature in different rooms. This means you can keep bedrooms or living areas cooler than less frequently used rooms, conserving energy and saving money on your electric bill.
  • Return air diffusion: Some HVAC systems are set up so as much air is circulated into the room as is circulated out, thus keeping temperature constant and air clean. Air circulation increases the ability of the unit to hold steady temperatures throughout your home or building.

Is the equipment compliant with safety standards?

There are a lot of health and environmental risks associated with the chemicals and equipment in heating and cooling systems. Federal and state governments issue safety standards to ensure that heating and cooling equipment works correctly and safely.

  • Environmental safety standards: HVAC units, air conditioners and heaters must comply with environmental codes for energy efficiency, clean air and more. It can be hard to know if a given unit meets these standards, but generally major manufacturers in the United States all meet these standards (or else they would not be able to pass inspections and market their products). To be sure, you can look for the Energy Star certification on any heating or air conditioning equipment (as well as many other home appliances), which indicates that the unit has met or exceeded efficiency standards.
  • Environmentally-friendly refrigerants: Air conditioners can be dangerous to the environment because of the chemicals in their refrigerants. Previously, most units used a refrigerant called R-22, but most manufacturers are phasing out production of these units because this chemical can be dangerous. Instead, look for a unit that uses R-410A, which is chlorine-free and safer for your family and the environment.
  • Ventilation standards: HVAC units must provide appropriate ventilation to lower the risk of respiratory infections and complications. The American Society of Heating and Air-Conditioning Engineers (ASHAE) sets the standards for ventilation, which are updated every few years; check to see that your installer is ASHAE-certified, which indicates that they follow the guidelines set by ASHAE.

Is the unit indoors or outdoors?

While heaters and furnaces are usually located inside, HVAC systems and air conditioners can contain both an indoor and outdoor unit for compressing and circulating air appropriately. If you have no outdoor space or prefer an indoor-only unit, your options will be more limited.

  • 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. This helps to ensure fresh air flow to the dwelling or building.
  • Ducts and vents: Complete HVAC systems typically feature an entire system of ducts throughout a home’s attic or basement area. These ducts connect to vents in every room, allowing warm and cool air to circulate in and out. If your home or building is not equipped with a ventilation system, you can have one installed, but the process is expensive. If you can’t afford or don’t want to install a ventilation system, you will need to rely on window air conditioning units, fans, space heaters and other similar solutions.
  • Furnace location: Many homes in cold regions or areas that experience a cold winter and that do not have a HVAC system often have a furnace instead, which is connected to a duct system to warm the home. Furnaces can be located in any indoor closet but generally should be inaccessible to pets and children, especially if the heating elements are exposed. Many people opt to put the furnace in the garage area. If there is no closet in your garage to house the furnace, consider having one built.

Who will work on the units?

Depending on what type of HVAC or individual heating and cooling units you have installed in your home, you may need to work with various specialists. Be sure there are installers or servic epeople available in your area.

  • 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.
  • Repair specialists: Repair specialists usually focus on the HVAC system as a whole or on individual units like the furnace, air conditioner or fireplace. They keep the heating or cooling system in good working order, perform inspections and complete repairs.
  • HVAC installers: Installers have specific skill sets related to installing new systems or units in homes and offices. They may or may not also repair systems and units.

What are the different types of heating and cooling systems?

HVAC systems

Homeowners, commercial builders and building owners may opt to install a complete heating, ventilation and air conditioning (HVAC) system to regulate temperature and air quality throughout the residence or business. Previous versions of these systems were known as “central heat and air,” but now feature air-purifying and regulating systems in addition to heating and cooling. Most small buildings and small- to medium-sized homes only need one HVAC unit; larger homes and buildings may have more than one unit.

Individual units

Some homeowners, contractors or building owners don’t need or want to install an entire HVAC system in a home or building. In those cases, individual units are available to heat, cool or control air quality. For instance, in some hot regions, heating systems are not necessary for comfort, so homeowners might prefer an air conditioning unit instead of an HVAC. It is often more affordable to install individual systems in older homes and buildings that might not be equipped for an HVAC system without a major renovation.

Portable units

Heating, cooling and air purifying systems can also be purchased in stand-alone units that are portable and plug into an electrical outlet or operate with batteries. For example, you may opt for a window air conditioning unit, tower heater, oscillating fan or HEPA filter instead of an entire HVAC system.

Who would benefit from a heating and cooling system?


Anyone who owns their home may want to install an HVAC system or individual unit. Homeowners with functional but outdated heating, air conditioning or ventilation units might want to replace them with more efficient or cost-effective systems or units.


People who rent a house, apartment or other space may need a portable heating or cooling solution, such as a window air conditioning unit, space heater or electric HEPA filter.

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. People with health issues who rent or don’t want to install an entire HVAC system might benefit from an electric HEPA filter.

Commercial building owners

Many commercial building owners have HVAC systems installed to keep workplace environments up to code and ensure a pleasant environment for employees, clients and customers. Building owners might also opt for portable units like space heaters or window air conditioning units.


Landlords may install HVAC systems or individual heating or cooling units in rental units to attract tenants and allow renters to feel more comfortable. Many states require landlords to keep buildings heated to a specific temperature during cold months or cooled during hot months.


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