Understanding Furnaces

Without a quality, reliable furnace, your home would be freezing in the winter. Given this, it is very important for you to understand the different kinds of furnaces that are available as well as their functions.

The selection process you may have gone through in the past to buy a furnace may have been more complicated than it is now. However, it is still essential to have some standards in place when it comes to selecting your furnace.

Some companies will try to sell you on the idea that all furnaces work the same. This is not the truth. Furthermore, the process of picking a design as well as the installation of the equipment that you select is the most crucial part of this procedure.

Even if you select the most expensive and best-quality furnace, if it is installed incorrectly, it will fail. In addition, it is important to know the factors that separate mid-range quality from high-end furnaces.

Furnace Efficiency- 80, 90, or 98+ Percent

If your old furnace is running poorly enough to make you consider purchasing a new one, it is most likely running at 50 to 60 percent AFUE (annual fuel utilization efficiency).

AFUE is what measures the percentage of natural gas turned into heat energy, which in turns heats the air in your home. With all that being said, a furnace that is running at only 50 percent AFUE is wasting half of the fuel that it is supposed to use.

When choosing a furnace for your home, you must consider how long you expect to live there. For example, if you expect to live in the house for five years or less, then getting an 80-90 percent AFUE furnace is fine. However, if you plan to live in your home for more than five years, then it is wise to go for a higher-end furnace.

Trane Furnaces

Trane furnaces are an excellent choice because they are built to last a long time. In fact, many people make this their choice for modern homes, as it comes with both central heating and air conditioning. Trane is a reliable brand that has your furnace needs covered, whether you are searching for single-stage heating, two-stage heating, or a variable-speed gas furnace.

Furthermore, Elite HVACs Heating and Air’s wide variety of Trane gas furnaces will keep your home warm, your bills low, and help those bitter winter months to be much more comfortable.

EMC Fan Motors with Variable Speeds

If you have ever had to turn up the television or raise your voice over the sound of your furnace running, we know why—because older furnaces have loud fan motors.

Variable-speed EMC fan motors are virtually silent and operate at different speeds. This flexibility results in a higher level of air quality and comfort for systems that utilize entire-house humidifiers and advanced air cleaners. We would recommend that you consider EMC fan motors with varying speeds as an option for your home.

Stage-1, Stage-2, and Fully-Modulated Furnaces

The stages mentioned are specifically about the flames that are in the furnace. The flame is what heats the heat exchanger, which in turn, transfers heat energy throughout your indoor environment as it passes through. This is due to the furnace’s fan motors that pull air from the return air ducts.

The furnace that you currently own may be a single-stage furnace. What this means is that the flame is either all the way up or off. In comparison, a two-stage heater has two flame settings which allow for more efficient operation.

Modern furnaces can also come with options such as modulating flames, where the flame can adjust at microscopic increments based on necessity. When you see a furnace with an AFUE rating of 95 percent or more, you can assume that it most likely has a fully-modulating flame, which is more effective than a two-stage operation.

Rebates with Elite HVACs

Feel free to contact us to find out what current rebates may apply to high-efficiency equipment. Frequently, a rebate will reduce the price gap of an otherwise more expensive cost for the equipment. When you do not have this initial investment cost, you will have the ability to spend less money on monthly gas bills too.

We contacted Elite HVACS on one of the hottest days of summer(we had no central air for 2weeks) and they sent some1 out same day to assess situation & decided to go with them for the work. I am happy to say that not only did we get the central air going but also replaced the heating unit which was old. Everyone we talked to from beginning to end were very professional, courteous and the work was very efficiently done. I would highly recommend this company.
