HVAC systems consist of several main components.

  • Heat pump or furnace for heating
  • Air conditioner or Heat Pump for Cooling
  • Ductwork for air circulation
  • Thermostat for temperature control
  • Air filters improve air quality

It is easy to understand how these systems operate. In heating mode air is heated by the furnace, heat pump, and then distributed via the ductwork. For cooling, the process is reversed, with the air conditioner or heat pump removing heat from the indoor air and expelling it outside.

HVAC systems come in different varieties, each with their own advantages.

  • Many homes use central air systems to provide heating and cooling. These systems utilize a network ducts.
  • Heat pumps are versatile and can be used in both hot and cold climates.
  • The Ductless Mini-Split is a great option for homes with no existing ductwork, or for rooms that need to be cooled.
  • Radiant heating systems are often installed under floors and provide a comfortable, efficient warmth.
  • Forced air systems heat the air in a furnace and distribute it via ducts.

Understanding these basics will help you communicate more effectively with HVAC professionals and make informed decisions about your home's heating and cooling needs.

You can improve your home's efficiency by following these simple tips. After making these changes, many homeowners have reported savings between 10-30%.

Maintenance and Troubleshooting Your HVAC System

Keep your HVAC running smoothly by performing regular maintenance. Homeowners can perform some DIY maintenance jobs, even though they may require professional knowledge.

  • Air filters should be changed regularly. Depending on the type of filter and usage, this can range from 1-3 months.
  • Airflow is improved by cleaning vents, registers and other air intakes.
  • Check thermostat batteries and replace them as necessary.

Professional maintenance should be scheduled at least once a year, ideally before the start of the heating or cooling season. These tune-ups are performed by a technician who will inspect, clean, and check various components. He or she will also ensure that the system is functioning correctly.

Most common HVAC issues have simple fixes. To start with, if the system doesn't work, you should check your thermostat and circuit breaker settings. The dampers inside your ductwork may be adjusted to fix an uneven heating or cooling. If you have a more complex issue or if it involves electrical components, refrigerant or other complicated items, then call a pro.
