What is two-stage heating? Two-stage heating enables the furnace to heat at two levels of output: high for cold winter days and low for mild ones. About 80 percent of the time, your home’s heating requirements can be met when the furnace is kept on the low setting, enabling your two-stage unit to operate for longer periods of time. Two-stage units also give more even heat distribution, fewer temperature swings, quiet operation, increased air filtration and energy efficiency. How does Precise Comfort™ technology work? Precise Comfort™ technology is an operating and control system used in Lennox furnaces. The technology can automatically adjust heat by increments as tiny as 1 percent, improving energy efficiency and helping you experience better comfort. How will my new furnace work differently from my old one? Modern furnaces are developed with a number of innovative features older furnaces don’t have. Today’s heating systems offer more even heating and are better at controlling airflow. Although the air coming out of your vents may seem cooler than your old furnace, the airflow is much better and more efficient. Another benefit of modern furnaces is their ability to work with other HVAC products as part of a high-efficiency whole home comfort system. When combined with a high-efficiency air conditioner, furnace blowers can more easily accommodate add-on cooling. Other innovations, such as Precise Comfort™ technology and variable speed motors, will help your furnace work more efficiently and quieter than ever. What energy efficiency standard should I look for in an air conditioner in Keokuk? The Department of Energy recently raised the minimum efficiency levels for air conditions, and the standards vary by region. Contact WM J Kraus & Son at 319-524-3714 to find out the requirements for the Keokuk area. How can I reduce my energy costs? Lennox carries a variety of HVAC products with high efficiency ratings, which can help lessen the amount of energy they require to work. Aside from picking products that have received Energy Star® certification or achieved high SEER ratings for air conditioners or AFUE ratings for furnaces, you can consider the following: Maintenance – ensuring your system obtains regular maintenance by a trained expert can keep your system working at its top performance. Zoning – zoning systems permit you to only heat or cool only certain areas of your home, so you won’t have to pay to heat or cool spaces that you don’t usually use. Programmable thermostats – using a programmable thermostat allows you to set the temperature in your home around your schedule. They can be programed to give you the comfort you desire when you’re home, and increase or decrease the temperature while you’re gone, helping you save on heating and cooling costs. Why should I buy from Lennox? There are various reasons to go with Lennox, but the top three are: Lennox is a name you know and trust – known around the world for quality HVAC products, you can rest assured Lennox will provide you with high quality equipment. Innovative and high quality products – Lennox has been on the leading edge of innovation in the heating and cooling industry for years.

Reputation of excellence – high quality products are not the only arena Lennox excels in. Lennox dealers, like WM J Kraus & Son, give you high quality service at all times, from your first consultation to your scheduled maintenance appointments. What can I do to improve my home’s indoor air quality? Strategies to boost your indoor air quality can be as simple as vacuuming your home to something as large as adding a new ventilation system. Overall, good IAQ has four strategies: Eliminate – decrease the pollutants floating in your air by cleaning your home routinely, particularly vacuuming carpet, washing linens and safely storing household chemicals. Ventilate – make sure your home is well-ventilated to move airborne pollutants out of your home. In newer homes, well-done insulation will hinder ventilation, so Lennox systems such as the Healthy Climate® ventilation system can help. These systems bring fresh air from outside into your home and direct the stale air out. Clean – correct air filters, such as our Healthy Climate® air filters, will ensure even the smallest particles don’t get through and are let out into your home. Germicidal lights can kill the germs that do make it through, and purification systems like the PureAir™ will help destroy odors and chemical vapors. Monitor – keep your humidity levels in check with a programmable thermostat. High temperatures and humidity levels can raise concentrations of mold, mildew and germs. A programmable thermostat will ensure your home is comfortable without letting humidity get too high. How can I find out which indoor air quality product will is right for my home? Try utilizing our Healthy Solution Finder, where you can pinpoint the indoor air quality issues that affect your home. After you choose the items that apply, the system will show the IAQ products that fit your needs. You can also call WM J Kraus & Son and walk our techs through some of the concerns you experience. They can evaluate your home and needs and provide options and answers. How does an air conditioner work? Most homeowners believe that air conditioners make your home cooler, but it actually removes the heat from your house, directing the hot air outside. That hot air moves across a cold indoor coil where refrigerant in the lines sends the heat to the coil in your outdoor unit, releasing it outside. This cycle continues until the indoor temperature reaches the desired level that you set on your thermostat. What is the minimum energy efficiency standard for air conditioners in my state? Due to the amount of energy used by heating and cooling systems, the Department of Energy (DOE) hiked up the minimum efficiency levels for air conditioners, heat pumps and packaged units manufactured after January 1, 2015. These levels are determined based on region and carry varying requirements based on your location. WM J Kraus & Son will be able to answer any questions you may have regarding these minimum requirements and let you know what choices are available when you’re looking for a replacement system. How can I confirm the model and serial numbers for my cooling unit? These numbers are located on a nameplate or sticker that is near your system’s service panel. The sticker is white with black letters and have both of these numbers located at the top of the sticker. M/N signifies model number while S/N is your serial number. What size equipment do I need for my home? There are a few ways to determine what size system will best suit your home, but the most reliable way to size a system is by having your local WM J Kraus & Son technician come out and perform a load calculation. This calculation considers your home’s: square footage, insulation value, amount of insulation, and a handful of other factors. Can frost, ice, dirt or other debris keep the outdoor unit of my cooling system from operating effectively? The short answer is “Yes.” Dirt and other debris can hinder your system’s ability to work efficiently. For heat pumps, it is not unusual to have frost or ice on them during the winter, but they also include defrost controls to ensure they work efficiently in those types of conditions. What is two-stage cooling? Two-stage cooling means that your cooling unit has two levels of operation. When summer is its warmest, the high setting kicks in, and when it’s cooler or more mild, it operates on the low setting. Most of the time, the lower setting is able to take care of your cooling needs, but even when the high setting starts up, you may not realize it because it can generate such even temperatures for your comfort. This also means a quieter cooling system, greater efficiency and better humidity control. Why is my system freezing up? Your system could be freezing up for a variety of reasons, but the most common are dirty filters, low refrigerant, a dirty evaporator coil and/or a faulty blower motor. Changing a filter is something homeowners take care of; however, you’ll need to call the professionals at WM J Kraus & Son at 319-524-3714 for other problems or if you have other questions or concerns. What is the best thermostat to use for my cooling system? Picking the best thermostat for your cooling system comes with a lot of considerations. That’s why it’s nice to have such a wide variety of choices from WM J Kraus & Son. Whether you’re in the market for for a programmable or non-programmable thermostat or want to join the smart home trend, there are various thermostats that you have to select from. Some thermostats will depend on what type of heating and cooling system you have, but the pros at WM J Kraus & Son will be able to help determine what options are best for your needs and your budget. What is a heat pump? Heat pumps can be a little confusing due to their name, but they actually take care of both your heating and cooling needs throughout the year. When it’s hot outside it works like an air conditioner in that it removes heat from your home, but when it cools off, the process gets turned around and it collects heat from outside and brings it inside. Heat pumps are also very efficient, and might produce up to two or three times more heat than the energy it uses. When replacing the outdoor unit, should the indoor unit also be replaced? Of course we think you should also replace your indoor system, but this is why: All outdoor cooling systems have a matching indoor unit that they are designed to work with to ensure efficient performance. When they aren’t paired with the other piece as a complete system, efficiency can be diminished. As with most products, advancements have brought about newer, more efficient ways of doing things. Heating and cooling systems are no different. These developments most importantly include greater heating and cooling efficiency, but also involve improved air handling, filtering and noise pollution reduction to name a few. Heating and cooling systems that are more than 10-15 years old normally need to be replaced. Not only do they consist of outdated technology, but they are also less efficient than more recent models. Buying a new indoor unit at the same time means you’ll have a matched system to provide you with improved comfort and efficiency for years to come. How can I tell if my solar HVAC system is performing to its maximum potential? The communication module on your SunSource® Home Energy System sends the system’s performance records for each module to a website. You may visit this website to see the system’s status, energy production and environmental benefits. The site also shows carbon offsets as it happens. Do I need an Internet connection to use the SunSource® communication module? Yes, an Internet connection is required for you to take advantage of the online monitoring system, which includes viewing energy production and environmental benefit information. The system’s performance-monitoring website is maintained by an independent third party, Enphase Energy Inc., and the monitoring service is provided free for five years. Do my solar modules need to be cleaned? In most regions, rain will be enough to keep the solar modules clean. If you are located in a dusty or industrial area, periodically spraying the modules with water can help improve performance. However, detergents and high-pressure hoses should never be used to clean solar modules. What is the best thermostat for my heating and cooling system? The right thermostat for you depends on your heating and cooling equipment. WM J Kraus & Son offers programmable and nonprogrammable thermostats that can help increase the efficiency of your HVAC systems. Check out our available products or contact us at 319-524-3714 to learn more. How can I control my energy bills? Heating and cooling can contribute to a significant chunk of your utility expenses. The innovative and high efficiency heating and cooling products available from Lennox® can help reduce these costs. If you’re looking for a new heating and/or cooling system, look for products with high SEER ratings for air conditioners and AFUE ratings for furnaces. SEER and AFUE are a measure of system efficiency, and the higher the number, the more efficient the product. Aside from purchasing a new home comfort system, consider these factors: 1. Is your product regularly maintained? Whether it’s a furnace or air conditioner, HVAC systems will opperate more efficiently after regular maintenance checks. 2. Do you need a zoning system? If there are areas of your home that are rarely used, a zoning system will allow you to heat or cool only the commonly used areas of your house. 3. Are you taking advantage of a programmable thermostat? According to the U.S. Department of Energy, programmable thermostats can reduce your heating costs by up to 35 percent, and your cooling costs by up to 25 percent. What are the benefits of zoning systems? Zoning your home allows you you the opportunity to divide areas of your residence and control the thermostat differently in each area. These systems are good for when you have spaces of your home that are infrequently used or when you and your family are always in disagreement of what the temperature in each area of your home should be. Zoning systems are almost noiseless and efficient, allowing you more control over the comfort of your home. Find out more about the zoning equipment available from WM J Kraus & Son.
