What is an HVAC system

Notes:

• Let’s cover the basics first: the initials “HVAC” stand for heating, ventilation, and air conditioning. An HVAC unit is responsible for keeping the temperature of your home within a comfortable standard range.
• Of course, there are many models, varieties, and brands that fall under the HVAC umbrella.
• You might have the popular split system with the heating inside and the AC outside. You may have a hybrid system that operates using one of two energy sources. Your system may be duct-free, with individual units in each part of the house, or it may be a packaged system whose parts are kept in one part of the home.
• Although all of these perform the same essential tasks, it’s a good idea to consider all your HVAC options if you’re in the market. The type of HVAC you choose should always be tailored to your home and your needs—and there’s a lot to consider before you buy.

How does an HVAC system work?

Notes:

• Your HVAC system combines central heating and cooling systems to “condition” the air around you, bringing it to a desirable temperature.
• To understand how an HVAC system works, you need to understand how various parts work together. In general, every system will work in the same way using the same core elements:

  • Thermostat:

    When you interact with the thermostat to change the desired temperature of your home, your HVAC system kicks in.

  • Modern thermostats can be set manually or programmed according to a schedule. Alternatively, when the temperature in your home falls outside of the expected range, your thermostat can automatically start your HVAC.

  • Furnace:

    This part of your HVAC requires the most space, so you’ll often find it in the attic or basement of your house. The furnace heats air and distributes it throughout your home. It can use a range of fuels, although most run on either natural gas or propane.

  • There are many types of furnaces, but they typically have a few core components: a burner to burn fuel, a heat exchanger to pick up heat and move it through your supply ducts, and ventilation pipes or a flue to transfer exhaust outside your home.

  • Air Conditioner:

    This part of your HVAC runs on electricity. The bulk of it can be found outside your house, with the exception of the evaporator coil. When warm air from within your home blows across it, the energy from its heat transfers to the refrigerant within.

  • This energy transfer is what helps to cool the air. The absorbed heat is blown outside, and the cooler air is blown inside.

  • Ducts:

    These are essentially tunnels through which hot or cold air moves into the interior of your home. The ducts are shared between both AC and heating.

How can you tell if there’s an issue with your HVAC?

Notes:

• Now that you know a little more about how your HVAC system works, how can you tell when there’s a problem? In general, your HVAC system can run for years with proper maintenance.
• But there are a few HVAC problems that should throw up a red flag:

  • Higher Bills:

    There is no “normal” cost of running an HVAC unit, as every household has a different system and uses it according to their preferences.

  • However, running your AC—which typically consumes more of a home’s energy than heating—can range from on average.
  • If you’re seeing higher bills than this, especially higher than your personal “normal,” it may indicate that your system isn’t running effectively.

  • Unpredictable Temperatures:

    Of all the common HVAC issues, this is the one that most frequently makes homeowners call for help.

  • Your HVAC should keep your home at a standard temperature throughout the day. If you find that the temperature shoots up or dips lower than this programming warrants, you might need to reach out for some HVAC help.

  • Strange Noices:

    Any sound outside of your HVAC’s range of “normal” noises are worth looking into. If you hear odd clicking, banging, or clattering, you’ll want to have an expert take a look.

  • Older Model:

    Your HVAC’s lifespan is typically . If you’re getting close to that number, you should consider getting an HVAC replacement.

  • Newer models are easier to program and much more energy-efficient, which is why this type of upgrade always makes our lists of ways to cut household expenses.

  • Unusual Smells:

    Any strange smells are a key sign you need someone to investigate. Smells may be musty, or you might smell chemicals or burning. If you notice any of these, ventilate your home and call an expert.
