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. Around 80 percent of the time, your home’s heating requirements can be met when the furnace is kept on the low setting, permitting your two-stage unit to run for longer periods of time. Two-stage units also provide more even heat distribution, fewer temperature swings, quiet operation, improved 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 small as 1 percent, boosting energy efficiency and helping you experience precise 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 provide more even heating and are better at regulating 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 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 energy efficiency standard should I look for in an air conditioner in Baltimore? The Department of Energy recently boosted the minimum efficiency levels for air conditions, and the standards vary by region. Contact Quality Refrigeration at 410-355-6010 to learn the requirements for the Baltimore 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 – making certain that your system receives regular maintenance by a trained expert can keep your system working at its peak performance. Zoning – zoning systems permit 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 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 throughout 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 Quality Refrigeration, give you high quality service at all times, from your first consultation to your routine maintenance appointments. What can I do to improve my home’s indoor air quality? Strategies to boost your indoor air quality can be as basic 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 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 destroy 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 run rampant. How can I find out which indoor air quality product will is right for my home? Try checking out our Healthy Solution Finder, where you can pinpoint the indoor air quality problems 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 Quality Refrigeration and walk our techs through some of the problems you experience. They can evaluate your home and needs and provide options and solutions. How does an air conditioner work? Many homeowners believe that air conditioners make it cooler in your house, but it actually removes the heat from your house, moving the hot air outside. That hot air flows 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) increased 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. Quality Refrigeration 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 searching for a replacement system. How can I confirm the model and serial numbers for my cooling unit? These numbers can be found 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 signifies 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 will best suit your home, but the most reliable way to choose a system is by having your local Quality Refrigeration 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,” because dirt and other debris can inhibit 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 that type of weather. What is two-stage cooling? Two-stage cooling means that your cooling unit has two levels of operation. When summer is its hottest, the high setting kicks in, 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 is in use, you may not realize it because it can generate such even temperatures for your comfort. This can also mean a quieter cooling system, greater efficiency and enhanced humidity control. Why is my system freezing up? Your system could be freezing up for a variety of reasons, but the most frequent are dirty filters, low refrigerant, a dirty evaporator coil and/or a faulty blower motor. Changing a filter is something you, the homeowner, can take care of; however, you’ll need to call the professionals at Quality Refrigeration at 410-355-6010 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 big variety of choices from Quality Refrigeration. Whether you’re looking 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 experts at Quality Refrigeration 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 tad 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 created to work with to ensure efficient performance. When they aren’t paired with the other piece as a total system, efficiency might be affected. 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 developments most importantly include better 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 today’s 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 full potential? The communication module on your SunSource® Home Energy System sends the system’s performance records for each module to a website. You can go to this website to learn about 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 offered by an independent third party, Enphase Energy Inc., and the monitoring service is provided at no cost for five years. Do my solar modules need to be cleaned? In most areas, rain will clean the solar modules off automatically. 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 clean solar modules. What is the best thermostat for my HVAC system? The right thermostat for you depends on your heating and cooling equipment. Quality Refrigeration sells programmable and nonprogrammable thermostats that can help enhance the efficiency of your HVAC systems. View our available products or contact us at 410-355-6010 to learn more. How can I control my energy costs? Heating and cooling can contribute to a significant chunk of your utility costs. The innovative and high efficiency HVAC products available from Lennox® can help reduce 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 additional factors: 1. Is your product 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 parts 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 systems give you the the comfort of sectioning parts of your house and control the thermostat differently in each area. Zoning tends to be ideal for when you have areas of your home that are seldom used or when you and your family are always in disagreement of the perfect temperature for the house. Zoning systems are nearly silent and efficient, allowing you more control over the comfort of your family home. Discover more about the zoning equipment available from Quality Refrigeration.
