How to Choose the Right Furnace

Are you thinking about upgrading your furnace but not quite sure where to begin?

We understand. Furnaces are more efficient than ever, with a plethora of features designed to keep you comfortable. They come in different sizes and shapes, some more powerful than others. They also have different price points based on their efficiency ratings.

The thermostat is the brains of your heating, ventilation, and air conditioning (HVAC) system. But it’s the furnace that provides all the muscle, teaming up with your ductwork to send warm air throughout your Colorado home.

And always remember, a happy home is a warm one! It would only take a few cold days in a row with no indoor heat for all the pipes in your home to freeze.

What matters most is to pick the right furnace that fits your budget and the size of your home. Our team at Kappler Mechanical has the knowledge and expertise to help you make that choice. We’re a trusted name in the Broomfield for creating healthy homes. Give us a call today—we can schedule a free consultation to help with your next home improvement project.

Choosing the Right Furnace by Fuel Type

Your first decision is easy: choosing the fuel type.

The most common source is natural gas. Your local utility company supplies the fuel delivered to your home through an underground gas line. The price of natural gas is relatively stable, so you don’t have to worry about cost fluctuations. Plus, you never need to worry about storage.

  • If you have access to a natural gas line, we strongly recommend a gas furnace. These furnaces have proven their value over the years for providing steady comfort on the coldest of days.
  • Oil furnaces are a popular alternative in the United States, particularly in parts of the Northeast that do not have easy access to natural gas. These types of furnaces last longer than a gas furnace but do not operate as efficiently. Oil prices fluctuate more than natural gas prices, making it harder to gauge your monthly expenses. Plus, you will need a storage tank for the oil.
  • Electric furnaces tend to last longer than gas furnaces and cost less to install. On the other hand, they are more expensive to operate and take longer to heat your home. Anyone living in a cold climate would enjoy more comfort with a gas or oil furnace.

Choosing the Right Furnace Speed

Furnaces run at different speeds. The operating speed you choose will impact your comfort, budget, and indoor air quality (IAQ).

Single-stage furnaces have just two settings, on or off. Your furnace switches on and continues to run to reach the desired temperature. Once it reaches the temperature, the furnace turns off. Single-stage furnaces are the most affordable models and easiest to install. But they are the least efficient and tend to create hot and cold spots in larger homes.

Two-stage furnaces run at full-speed and half-speed. This allows your furnace to heat your home more evenly, producing a more consistent temperature from room to room. In addition to producing better heating, the half-speed setting is much quieter.

Variable speed furnaces are the gold standard of the heating world. These models adjust their speeds to provide precise comfort. They run longer at slower speeds, improving efficiencies while lowering your energy bills. Because they do not frequently cycle on and off, these systems tend to have fewer breakdowns.

Variable speed furnaces are much more adept in maintaining your indoor air quality, catching harmful particles, and eliminating excess moisture that causes mold growth. Larger homes benefit tremendously from variable speed furnaces.

Choosing an Efficient Furnace

The AFUE (annual fuel utilization efficiency) rating on your furnace indicates how much energy it converts. An energy-efficient furnace with an AFUE rating of 95 can convert 95 percent of the energy it consumes into heat.

The higher the AFUE rating, the more money you save on monthly utility bills. Energy-efficient furnaces emit fewer greenhouse gases and make less noise when they operate. If you want to reduce your home’s carbon footprint, the perfect place to start is with your heating and cooling equipment!

How Much Money Can a New Furnace Save You?


Our AFUE energy savings calculator can help determine how much you could save on your utility bills. Just enter your current unit’s AFUE value and compare it to a newer, more efficient system.
