A single stage cooling is an air conditioner that operates at its full capacity all the time. When I size air conditioners in this area where I work, I size them for what it's 88 degrees outside. That's when they need at its full capacity. The benefits of a single air conditioner are a lower initial cost. As well, as to cool the home that it's actually design for. An example of a signle stage air conditioner is the XR 14 air conditioners. As well as the XL 16 air conditioner. A perfect fit for a single air conditioner would be a customer that has as small square footage home and if they don't have temperature swings in the house.
Is an air conditioner that has multi-stages of cooling. The first stage usually, operates at about 60-65 percent of capacity. The second stage operates at 100 percent capacity. A two-stage air conditioner is going to have the ability to be able to remove moisutre much better. The reason to this is because it has a longer run time, but those run times are using less energy. An example would be a product that has two stage of cooling would be an XR 17 model. As well as an XL 18 model. The right fit for a two-stage air conditioner would be a homeowner that is having issues controlling temperatures throughout the house. If the person has a two-story home, a multi-stage would be a much better fit for them.
Is an outdoor unit with a compressor that's varies in stages? It actually starts at 35 percent and goes to 100 percent. And it's all based on the outdoor temporature, the indoor temperature, the run time that is needed. The benefits of a variable speed air conditioner are that you would have a better temperature controlling within the house to within a half degree or less. You would have a better humidity control. An example that has variable speed technology would be X v 18 air conditioner and the XV 20 air conditioner. This is for big houses that have an uneven temperature swings and higher humidity. It's a better candidate for the variable speed.
When you are looking around for a new furnace, you would come across with three different types. A single stage, two-stages and modulating. You may wonder what are the differences between all three and which one is better for your home.
Single stage furnace only has one setting. Which is high heat. On a call for heat, they immediately start running at full capacity no matter what temperature is outside until the signal coming from the thermostat has turn off. These types of furnaces are best suited for budget-concious consumers so in the long run upfront cost savings are not realized.
Two stages gas furnaces have two settings high fire and low fire. Here is how it works. On a typical heating cycle, the furnace will start out running on low fire consuming less gas and electricity. While providing heat and gaining efficiency. After 7-10 minutes, the furnace begins to operate very efficiency because is warmed up. It will jump up into high fire and finish out the heating cycle at full capacity. Control of the high and low burner timing are made by the installers as part of a new furnace for installation. You can control the two-stage gas furnace by using a thermostat. Two stage furnaces are considered more energy efficient than single stage because they are not always running at a full heating capacity of the appliance and are often equipped with an ECM blower motor whcih will also save you electricity costs.
Modulating furnaces gas furnaces are at the top end of the gas furnace spectrum. Are considered to be the most efficient of the three but an added price over two stage or single stage furnaces heating from a modulating furnace ramps up in increments to maintain a consistent temperature and the duct work is always warmed up so there is little efficiency lost during the warming process.
When you are buying a new furnace, you will almost always need to invest in a new thermostat controller specifically designed for this type of furnace to get the most out of the furnace. If you are planning to stay in your home for the long term, a modulating gas furnace may be the right fit for you.
