What to Look For in an HVAC Furnace for Your Property

Louisville, Kentucky’s cold season lasts from November 30 to February 28. While there is still time before it gets too chilly out, it’s best to check your furnace and replace it now, if needed.

What should you look for in an HVAC furnace for your property? Keep reading to learn about the main components.

Types of Furnaces

The first thing to consider when looking for an HVAC furnace is the type of furnace that you need. On the market, there are four different types:

  1. Electric
  2. Oil
  3. Natural gas
  4. Propane

Each type heats the air differently and the operation costs vary.

Electric furnaces are often the cheapest and easiest to maintain and install. They can be expensive to operate because they rely solely on electricity.

Oil furnaces draw oil from a tank in a burning chamber. You’ll need an oil tank that is buried near the home, but you benefit from quicker home heating.

Natural gas furnaces are affordable when you live near a natural gas line. Propane furnaces operate similarly but don’t require a flue and are more efficient.

Single-Stage Heat vs. Multistage Heat

Consider how many stages you want your furnace to have. There are a few options on the market, such as single-stage heat, multistage heat, and modulating heat.

Older furnaces use a single-stage heat process with one size flame that is either off or on. Since it has one flame setting, it will go off and on throughout the day to match temperature fluctuations.

Multistage heat refers to two flames. There is a small one for mild weather and a large one for when the weather is much colder. It’s more precise than single-stage because of the two flames.

Modulating heat furnaces are the most accurate because they can control flame sizes to meet the established thermostat temperature.

AFUE Rating

Annualized fuel utilization efficiency (AFUE) ratings reflect how much heat is produced for each dollar spent.

You’ll spend less on fuel when the AFUE rating is higher. In an ideal world, you’ll want a furnace that has an AFUE rating in the 90s. These are the most energy-efficient furnaces available.

However, you’ll have to prepare to pay more for a higher AFUE rating. The cost savings, in the long run, could be worth the upfront cost.


Lastly, you’ll need something you can afford. Set a budget to ensure you get the factors you need for a price that won’t break the bank.

Whether you want a gas furnace or a central heating system, your replacement furnace should be the correct size for your home. Otherwise, you’ll be spending more money to keep your home warm.
