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 kept on the low setting, enabling 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, better air filtration and energy efficiency. What is Precise Comfort™ technology? Lennox’s Precise Comfort™ technology is an operating and control system that allows a furnace to adjust heat and airflow by amazingly small amounts, as low as a 1 percent change. The system is automatic and operates similar to cruise control, making adjustments gradually to meet your comfort demands with energy efficiency. Will my new furnace work differently than my old one? Depending on how old your previous furnace was, you could experience a variety of differences. Furnaces today are designed to give more even and efficient heating than ever before. Modern furnaces also better regulate temperature and air flow, moving more air over the heat exchanger than older furnaces. Additionally, new furnaces are created to operate with other high-efficiency HVAC products, such as air conditioners. The air conditioner blowers give your heating system an extra bump so it can deliver cool air around your home efficiently. Special features like variable speed motors will also help decrease noise associated with operating your equipment and easily meet your family’s airflow needs. What is the energy efficiency standard for air conditioners? The Department of Energy recently raised the minimum efficiency levels for air conditioners, heat pumps and packaged units made after Jan. 1, 2015, since heating and cooling contributes significantly to a home’s total energy usage. The requirements vary by region, so call Superior Comfort Systems for the efficiency standards for Hendersonville. How can I reduce my energy costs? Lennox carries a host of HVAC products with high efficiency ratings, which can help lessen 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 consider the following: Maintenance – making sure your system gets regular maintenance by a trained expert can keep your system operating at its best 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 typically utilize. 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 away, 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: You know and trust the name – Lennox is known around the world for its quality home comfort products. Innovation and high quality – Lennox is an industry leader, giving you a large line of innovative solutions for your home comfort needs. Commitment to excellence – We are committed to giving customers not only quality products, but also quality service. You can trust Lennox dealers, like those of us at Superior Comfort Systems, to help you find the right system for your home, expertly install it, and keep it working smoothly every time. How can I improve my home’s indoor air quality? Increasing your home’s indoor air quality starts with four basic strategies: Eliminate – poor indoor air quality leaves your home filled with air pollutants floating around your home, so to improve IAQ, the first step is to get rid of as many pollutants as possible. You can easily do this is by cleaning and vacuuming at least once a week, routinely washing linens and storing cleaning products safely. Ventilate – proper insulation is great for keeping your home warm in the winter and cool in the summer, but it also makes it more difficult for airborne pollutants to escape. Products like our Healthy Climate® ventilation system help swap stale air for fresh, filtered outside air. Clean – good ventilation and frequent cleaning are a start, but Healthy Climate® air filters, germicidal lights and PureAire™ purification systems take your IAQ to the next level by holding microscopic particles, killing germs and removing particles and germs while destroying chemical vapors. Monitor – programmable thermostats will help you monitor the humidity levels and temperature to help prevent particles and germs from building up and keep your home comfortable. How do I know which indoor air quality product will work best for my home? Our Healthy Solution Finder lets you pick details specific to your family and home and will help you find equipment best suited to meet your needs. You may also consult with Superior Comfort Systems techs who can make a recommendation based on their evaluations of your home and current indoor comfort system. 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 inside your home, directing 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 the heat outside. This procedure continues until the indoor temperature reaches the temp that was set on your thermostat. What is the minimum energy efficiency standard for air conditioners in my state? Due to the high 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 regionally and carry varying requirements based on your location. Superior Comfort Systems can 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 is white with black letters and have both of these numbers located at 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 will best suit your home, but the most reliable way to size a system is by having your local Superior Comfort Systems 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 impede 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 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 kicks in, and when it’s cooler or more mild, it operates on the low setting. Usually, 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 generate 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? When your cooling unit freezes up, there are a variety of reasons why it could be doing so. The most frequent reasons include: dirty filters, low refrigerant, a dirty evaporative coil and a faulty blower motor or relay. A dirty filter is something you can change as a homeowner, but the others need to be fixed by a professional like those at Superior Comfort Systems. Contact them at 828-775-5176 with any additional questions. 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 great variety of choices from Superior Comfort Systems. Whether you’re searching 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 Superior Comfort Systems 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 meet 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 reversed 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 designed to work with to ensure efficient performance. When they aren’t paired with the other unit as a complete system, efficiency might be affected. As with many products, advancements have brought about newer, more efficient ways of doing things. Heating and cooling systems are no different. These developments most importantly include improved heating and cooling efficiency, but also consist of 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. Adding a new indoor unit at the same time means you’ll have a matched system to provide you with better 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 data for each module to a website. You may visit this website to learn about the system’s status, energy production and environmental benefits. The site also shows carbon offsets in real time. Will I need an Internet connection to use the SunSource® communication module? Yes, an Internet connection is necessary for you to take advantage of the online monitoring system, which includes accessing 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 free of charge for five years. Do I need to clean my solar modules? In most areas, rain will clean the solar modules off automatically. 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 rinse solar modules. What is the best thermostat for my home comfort system? The right thermostat for you depends on your heating and cooling equipment. Superior Comfort Systems offers programmable and nonprogrammable thermostats that can help enhance the efficiency of your HVAC systems. View our available products or contact us at 828-775-5176 to learn more. How can I control my energy expenses? Heating and cooling can contribute to a significant amount 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 equipment 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 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 parts of your house. 3. Are you taking advantage of a programmable thermostat? According to the U.S. Department of Energy, programmable thermostats could 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 areas of your residence and control the temperature 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 how hot or cold it ought to be inside. Zoning systems are nearly silent and efficient, allowing you more control over the comfort of your home. Learn more about the equipment available from Superior Comfort Systems.
