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. Around 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 work 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. 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 little as 1 percent, improving energy efficiency and helping you experience better comfort. Will my new furnace work differently than my old one? Modern furnaces are designed with a host 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 bonus 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 operate more efficiently and quieter than ever. What is the energy efficiency standard for air conditioners? The Department of Energy recently raised the minimum efficiency levels for air conditions, and the standards vary by region. Contact KDM Service Corporation at 205-758-2703 to find the requirements for the Tuscaloosa area. How can I reduce my energy costs? Lennox carries a number of HVAC products with high efficiency ratings, which can help cut back the amount of energy they require to operate. Aside from choosing 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 gets regular maintenance by a trained technician can keep your system running at its top performance. Zoning – zoning systems allow you to only heat or cool only targeted 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 according to 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 a Lennox product? There are various reasons to pick Lennox, but the top three are: Lennox is a name you know and trust – known across 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 at the forefront 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 KDM Service Corporation, offer high quality service at all times, from your first consultation to your scheduled maintenance appointments. How can I improve my home’s indoor air quality? Strategies to increase your indoor air quality can be as easy as vacuuming your home to something as large as installing a new ventilation system. Overall, good IAQ involves 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 – the right air filters, such as our Healthy Climate® air filters, will make certain 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 get rid of odors and chemical vapors. Monitor – keep your humidity levels in check with a programmable thermostat. High temperatures and humidity levels can elevate 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 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 match your needs. You can also call KDM Service Corporation and walk our techs through some of the problems you experience. They can evaluate your home and needs and provide options and answers. How does an air conditioner work? Many 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 goes across a cold indoor coil where refrigerant in the lines sends the heat to the coil in your outdoor unit, releasing it outside. This procedure continues until the indoor temperature reaches the temperature 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) raised 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. KDM Service Corporation 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 will be 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 couple 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 KDM Service Corporation technician come out and perform a load calculation. This calculation considers your home’s: square footage, insulation value, amount of insulation, and a number 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 normal to have frost or ice on them during the winter, but they also are built with 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 is used, and when it’s cooler or more mild, it operates on the low setting. Typically, the lower setting is able to 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 also means 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 couple 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 should call the professionals at KDM Service Corporation at 205-758-2703 for other problems or if you have other questions or concerns. What is the best thermostat to use for my cooling system? Choosing 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 KDM Service Corporation. Whether you’re searching for a programmable or non-programmable thermostat or want to join the smart home trend, there are a number of thermostats that you have to choose from. Some thermostats will depend on what type of heating and cooling system you have, but the pros at KDM Service Corporation will be able to help determine what options meet your needs and your budget. What is a heat pump? Heat pumps can be a bit confusing due to their name, but they actually cover both your heating and cooling needs year-round. 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 advise you to also replace your indoor system, but this is why: All outdoor cooling systems have a matching indoor unit that they are created to work with to ensure efficient performance. When they aren’t paired with the other part as a whole system, efficiency might 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 typically need to be replaced. Not only do they have outdated technology, but they are also less efficient than more recent models. Getting 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 do I know 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 view the system’s status, energy production and environmental benefits. The site also shows carbon offsets as it happens. Will I need an Internet connection to use the SunSource® communication module? Yes, an Internet connection is needed 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 provided by an independent third party, Enphase Energy Inc., and the monitoring service is provided free for five years. Should I clean my solar modules? In most regions, rain will be enough to keep the solar modules clean. If you reside 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 HVAC system? The best thermostat for you depends on your heating and cooling equipment. KDM Service Corporation sells programmable and nonprogrammable thermostats that can help improve the efficiency of your HVAC systems. Check out our available products or contact us at 205-758-2703 to learn more. How can I control my energy bills? Heating and cooling can represent a significant amount of your utility expenses. The innovative and high efficiency heating and cooling products available from Lennox® can help decrease 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 product efficiency, and the higher the number, the more efficient the product. Aside from 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 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 may 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 equipment gives you the opportunity to divide parts of your residence and control the temperature differently in each part of your home. These systems are ideal for when you have areas of your home that are rarely used or when you and your family are often in disagreement of how hot or cold it ought to be inside. Zoning systems are almost noiseless and efficient, allowing you more control over the comfort of your home. Find out more about the zoning systems available from KDM Service Corporation.
