Residential Heating FAQ: What Is a Dual Fuel System and Do I Need One?

Monday, November 19th, 2012

Are you considering a dual fuel system but not sure if that is the right type of heat pump system for your home? Call the Bolingbrook heating experts at DuAll Heating & Cooling if you would like to know more about the benefits of a dual fuel system. We can explain the advantages of dual fuel over a standard air source heat pump system, and we’ll be glad to assess your current system to let you know if an upgrade would be a cost-effective choice.

Backup Heating with an Air Source Heat Pump

If you have an existing air source heat pump, you probably have a backup heater. Many people believe that a heat pump will not heat the home during times of extreme cold weather. However, this is not the case. Air source heat pumps—at least the standard ones—simply do not work as efficiently during freezing weather. Using a backup heater is mostly about getting more efficient heat in the winter.

Backup heat is usually provided by a gas furnace, since natural gas tends to be more efficient than electricity. And with a duel fuel or hybrid system, the heat pump control center will know when to switch from the electric compressor to the gas furnace for more efficiency. Before you decide to upgrade, there are a few factors to consider.

Here’s how you can compare the costs of other heat pumps that don’t use this type of technology. First, make sure you know the condition and efficiency of your current heat pump if you have one. If your old system was not sized correctly, or if you’ve made significant improvements to increase overall home efficiency, you may want to upgrade to a more efficient heating and cooling system to take full advantage of those changes.

Make sure you also understand efficiency ratings. They are measured differently for the different types of systems. Check with your heating contractor if you aren’t sure how to read the numbers. You can also just look for the Energy Star label. These models with be about 10% more efficient than the ones that meet today’s basic energy requirements. Also be sure to compare the cost of fuel in your area, and keep a record of your bills every winter so that you can see when you were paying more in heating costs.

Residential Heating Tip: Why Furnace Size Matters

Monday, October 22nd, 2012

Whether you are installing a new furnace or retrofitting your old heating system, you must get the proper size for your home and heating needs. There are several reasons for this. You can always call the Bolingbrook heating experts at DuAll Heating & Cooling if you would like a better understanding of furnace size and why it is important.

To get you started, here are a few of the main reasons that not properly sizing a furnace can end up costing you more in the long run, especially an oversized furnace.

We are focusing on oversized furnaces since this is the most common problem in our industry. Many contractors will try to talk you into getting a furnace that is too big for your heating needs. In addition, the size of your ductwork must be able to deliver the extra BTUs of heating output. If not, you may end up paying more to repair a furnace that has broken down due to constant cycling due to limit switch problems. Not only that, it could wear out the heat exchanger, which is a costly replacement.

The BTU capacity of your new furnace should depend on other factors as well, including the square footage of the space you need to heat and how many doors and windows are in your home. The location and layout will also play a role in the sizing process. Make sure your thermostats are up to date as well. For new high-efficiency furnaces, you’ll need to install a two – stage thermostat that can handle the variable speeds of the fan blower.

If you have further questions, call the Bolingbrook heating professionals at DuAll Heating & Cooling. We can answer all your questions and set up a consultation with a technician to assess your home and current heating system if you are interested in a furnace installation.
