What Are the Major Differences Between Heat Pumps and Furnaces?

When selecting a new heating system, you’ll have many choices, thanks to the vast selection of quality heating units on the market. Your first step should be choosing which type of heating system is right for you; a heat pump or a furnace. We’ve put together some information to help you learn about these two heating options, including the differences between them as well as their benefits and drawbacks.

Below are some of the distinct differences you’ll find between heat pumps and furnaces:

  • Furnaces provide only heating, while heat pumps are capable of providing heating and cooling. Heat pumps use refrigerants, like an air conditioner does, giving it the power to serve you both ways.
  • Heat pumps are generally powered by electricity. Electric furnaces are available, though many burn fuels, such as natural gas, propane, or oil.
  • Furnaces heat air using a flame while heat pumps extract heat from an outside source. Heat pumps can be either air source or geothermal.

Benefits and Drawbacks of Heat Pumps and Furnaces:

  • Heat pumps provide heating and cooling, so you only have to buy one unit for year-round comfort. A furnace cannot provide cooling, so it will be necessary to also purchase a cooling system.
  • Heat pumps can be up to 40 percent more efficient than gas furnaces.
  • Furnaces can deliver higher temperatures than heat pumps are capable of, making some feel more comfortable indoors.
  • Heat pumps can provide heating and cooling in areas where natural gas and other heating fuels are not accessible.
  • Heat pumps aren’t as efficient when temperatures drop below 40 degrees Fahrenheit. Gas heating is more efficient than heat pumps at lower temperatures.
  • Furnaces can be used as a backup heat source to a heat pump, providing heating when temperatures drop too low for a heat pump to be efficient.
  • Heat pumps are usually more expensive to buy, but cheaper to operate. Furnaces are usually cheaper to purchase, but more expensive to operate.
  • Furnaces require proper venting to reduce the risk of carbon monoxide buildup in the home. Since heat pumps do not burn fuel, they will not produce carbon monoxide.

  • Humming: A humming noise which occurs as your furnace operates can be an indication that your furnace motor may die soon, which will leave you without heat.
  • Squealing: If your furnace has not been properly maintained, bearings may not have proper lubrication, which can cause a high-pitched squeal as your furnace runs. Without proper lubrication, these moving parts will wear out much quicker than normal, decreasing the service life of your furnace. Squealing may also indicate a slipped blower belt. If your blower belt has malfunctioned, the furnace blower will not be able to push heated air into your home.
  • Grinding: Grinding can indicate that components of your furnace motor require replacement, such as ball bearings and belts.
  • Clicking: Clicking is normal as a furnace turns on and off, but if it repeatedly occurs as the furnace runs, you should call for professional troubleshooting, as it can indicate can indicate problems with your compressor or control panel.


5 Reasons to Install a Geothermal Heating Unit

Geothermal Heating and Cooling in Harrisburg, Huntersville, Charlotte, North CarolinaGeothermal heating systems utilize Earth’s below-ground energy to heat and cool homes and businesses across Charlotte, North Carolina. These systems are composed of a ground loop component which extracts energy and a heat pump which distributes heated or cooled air throughout your indoor spaces. While there are many heating systems to choose from, here are five strong reasons why you should choose geothermal.

1. Efficient heating and cooling

Geothermal heating and cooling is a clean, green comfort system. It burns no fossil fuels to heat your home, like furnaces do. Its heat pump component consumes very little electricity, and it is highly efficient — about 400 percent efficient, compared to the 78 to 90 percent efficiency you’ll find with a fossil fuel burning furnace.

2. Environmentally-friendly, renewable energy

A geothermal heating system taps into energy stored below Earth’s surface. This energy source is considered to be endless, unlike our limited supply of fossil fuels. When using a geothermal heating system, you’ll be accessing a sustainable fuel supply that won’t have the significant impact that consuming fossil fuels do. These systems do not produce the high levels of carbon emissions that gas burning furnaces and traditional air conditioners do.

3. Annual savings on heating and cooling      

Heat pumps are extremely efficient, using very little electric energy to heat and cool your home. Your electric bill will be reduced significantly, and you can eliminate all fuel usage associated with heating. With a correctly designed and installed geothermal heating unit, you’ll experience less energy loss, helping you save even more. Installing a geothermal heating unit can save you up to 65 percent on your monthly heating and cooling costs; considering that heating and cooling make up approximately half of the average household’s energy consumption, this cost savings is quite significant. When switching to this green heating source, you’ll save a lot of green with lower utility bills.

4. Improved comfort

Installing a geothermal heating unit will improve your comfort all year long. They do not have the temperature fluctuations you may experience when using other types of heating systems which can cause you to feel uncomfortable. The heat pump offers quieter operation than a furnace, so you won’t be bothered.

5. Hot water, too!

A geothermal heating system can help you save energy for water heating in addition to space heating. Depending on the configuration of your geothermal heating system, it can also provide hot water for your home or business, at little to no cost. By using the excess heat from the heating system, a Hot Water Pre-Heater can provide for approximately 50 percent of the hot water needed by the average home or business.

Breathe Easy and Improve Your Indoor Air Quality

Airborne microorganisms are tiny, but can cause big problems for you and your children and pets. From allergies to asthma and infections, some of these germs and bacteria are actually originating in something you use to keep yourself more comfortable – your AC unit.

Benefits of UV Light Charlotte Harrisburg, North CarolinaMany people claim that their AC unit causes a multitude of illnesses including colds in the summer, increased allergies, mold reactions, and other bodily responses to unnatural coldness. It is true that there is no air like fresh air. But AC makes us comfortable in the hottest months – and shouldn’t there be a way to be comfortable and healthy?

UV lighting in your AC unit effectively kills airborne mold and bacteria. The particles pass through the unit with the UV lights, which kill the dangerous pathogens, so they do not move back into your home and make your family sick. Filters in your AC units catch some of these germs, but not all. If the filter is particularly dirty or ineffective, it can actually become a breeding ground for new colonies of germs.

Although upfront, UV lights cost a couple hundred dollars to install, the benefits far outweigh the cost.

UV lights can save on energy consumption while improving airflow and comfort levels. Although they do not save energy themselves, UV lights improve and restore coil performance, ultimately reducing energy consumption by up to 35 percent. In a year or less, UV lights can save you what you spent on your bills, and as one person is quoted saying: “the cost is far, far less than I pay for health insurance!”
