Call 847-306-8990 to find out more. What is two-stage heating? Two-stage heating permits the furnace to heat at two levels of output: high for cold winter days and low for mild ones. Approximately 80 percent of the time, your home’s heating requirements can be met when the furnace is left on the low setting, permitting your two-stage unit to run for longer periods of time. Two-stage units also give more even heat distribution, fewer temperature swings, quiet operation, better air filtration and energy efficiency. What is Precise Comfort™ technology? Precise Comfort™ technology is an operating and control system used in Lennox furnaces. The technology can automatically adjust heat by increments as small as 1 percent, improving energy efficiency and helping you experience more comfort. Will my new furnace work differently than my old one? Modern furnaces are designed with a number of innovative features older furnaces don’t have. Today’s heating systems give you more even heating and are better at governing 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 bonus of modern furnaces is their ability to integrate 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 operate more efficiently and quieter than ever. What is the energy efficiency standard for air conditioners? The Department of Energy recently boosted the minimum efficiency levels for air conditions, and the standards vary by region. Contact Assured Appliance and Heating & Air at 847-306-8990 to find the requirements for the Genoa area. How can I reduce my energy costs? Lennox offers a variety of HVAC products with high efficiency ratings, which can help cut back the amount of energy they require to run. 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 think about the following: Maintenance – making sure your system obtains regular maintenance by a trained expert can keep your system operating at its best performance. Zoning – zoning systems enable you to only heat or cool only specific areas of your home, so you won’t have to pay to heat or cool spaces that you use infrequently. Programmable thermostats – using a programmable thermostat allows you to set the temperature in your home around your schedule. They can be programed to provide the comfort you desire when you’re home, and increase or decrease the temperature while you’re away, helping you save on heating and cooling costs. Why should I buy a Lennox product? There are a number of 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. High quality furnaces, air conditioners and home comfort systems include innovative features to help your home stay more comfortable and energy efficient. Reputation of excellence – high quality products are not the only arena Lennox excels in. Lennox dealers, like Assured Appliance and Heating & Air, provide high quality service at all times, from your first consultation to your planned maintenance appointments. How can I improve my home’s indoor air quality? Strategies to improve your indoor air quality can be as basic as vacuuming your home to something as large as installing a new ventilation system. Overall, good IAQ has four strategies: Eliminate – get rid of the pollutants floating in your air by cleaning your home regularly, 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 prevent 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 diminish odors and chemical vapors. Monitor – keep your humidity levels in check with a programmable thermostat. High temperatures and humidity levels can increase concentrations of mold, mildew and germs. A programmable thermostat will make certain that your home is comfortable without letting humidity get too high. How do I know which indoor air quality product will work best for my home? Try checking out our Healthy Solution Finder, where you can select the indoor air quality problems that affect your home. After you pick the items that apply, the system will show the IAQ products that fit your needs. You can also call Assured Appliance and Heating & Air and walk our techs through some of the problems you experience. They can evaluate your home and needs and provide options and explanations. How does an air conditioner work? Most homeowners believe that air conditioners make the air in your home cooler, but it actually removes the heat from your house, sending the hot air outside. That hot air goes across a cold indoor coil where refrigerant in the lines sends the heat to the coil in your outdoor unit, releasing the hot air 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 increasing 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 by region and carry varying requirements based on your location. Assured Appliance and Heating & Air can help 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 around the top of the sticker. M/N denotes model number while S/N is your serial number. What size equipment do I need for my home? There are a handful of ways to determine what size system is the best fit for your home, but the most reliable way to choose a system is by having your local Assured Appliance and Heating & Air technician come out and perform a load calculation. This calculation considers your home’s: square footage, insulation value, amount of insulation, and a variety 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 impede your system’s ability to work efficiently. For heat pumps, it is normal to have frost or ice on them during the winter, but they also include defrost controls to ensure they work efficiently in those kinds of weather. What is two-stage cooling? Two-stage cooling means that your cooling unit has two levels of operation. When summer is in its hottest weeks, the high setting is used, and when it’s cooler or more mild, the low setting handles the duties. Typically, the lower setting can take care of your cooling needs, but even when the high setting kicks in, you may not realize it because it can produce such even temperatures for your comfort. This can also mean a quieter cooling system, greater efficiency and better humidity control. Why is my cooling unit freezing up? Your system could be freezing up for a variety of reasons, but the most typical are dirty filters, low refrigerant, a dirty evaporator coil and/or a faulty blower motor. Changing a filter is something any homeowner take care of; however, you should call the professionals at Assured Appliance and Heating & Air at 847-306-8990 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 to think about. That’s why it’s nice to have such a great variety of choices from Assured Appliance and Heating & Air. 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 pick from. Some thermostats will depend on what type of heating and cooling system you have, but the team at Assured Appliance and Heating & Air will be able to help determine what options fit your needs and your budget. What is a heat pump? Heat pumps can be a tad confusing due to their name, but they actually cover both your heating and cooling needs throughout the year. When it’s hot outside it operates like an air conditioner in that it removes heat from your home, but when it cools off, the process gets reversed and it collects heat from outside and brings it inside. Heat pumps are also very efficient, and could 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 unit as a total system, efficiency might be diminished. As with a lot of products, advancements have brought about newer, more efficient ways of doing things. Heating and cooling systems are no different. These advances most importantly include better heating and cooling efficiency, but also include 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 have outdated technology, but they are also less efficient than newer models. Getting a new indoor unit at the same time means you’ll have a matched system to provide you with even more comfort and efficiency for years to come. How can I tell if my solar HVAC system is performing to its potential? The communication module on your SunSource® Home Energy System sends the system’s performance records for each module to a website. You can visit this website to view the system’s status, energy production and environmental benefits. The site also shows real time updates of carbon offsets. 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 seeing 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 at no cost for five years. Should I clean my solar modules? 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 could help improve performance. However, detergents and high-pressure hoses should never be used to rinse solar modules. What is the best thermostat for my home comfort system? The best thermostat for you depends on your heating and cooling equipment. Assured Appliance and Heating & Air sells programmable and nonprogrammable thermostats that can help enhance the efficiency of your HVAC systems. Check out our available products or contact us at 847-306-8990 to learn more. How can I control my energy expenses? Heating and cooling can represent a significant chunk of your utility bill. The innovative and high efficiency heating and air conditioning products available from Lennox® can help decrease these costs. If you’re in the market 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 product efficiency, and the higher the number, the more efficient the product. Other than purchasing a new home comfort system, consider these other factors: 1. Is your system regularly maintained? Whether it’s a furnace or air conditioner, HVAC systems will run 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 utilizing 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 systems give you the the comfort of sectioning parts of your residence and control the air differently in each part of your home. Zoning equipment is best for when you have spaces of your home that are rarely used or when you and your family are often in disagreement of what the temperature in each area of your home should be. Zoning systems are almost noiseless and efficient, giving you more control over the comfort of your home. Learn more about the equipment available from Assured Appliance and Heating & Air.
