With two-stage heating, furnaces may run on two different levels: high and low. Since you can heat your home on the low setting a majority of the time, a two-stage furnace can run longer and more efficiently. Two-stage heating also works more quietly than traditional furnaces and can give you more even heat distribution and fewer temperature swings. How does Precise Comfort™ technology work? 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 runs similar to cruise control, making adjustments gradually to meet your comfort demands with energy efficiency. How will my new furnace work differently from my old one? Depending on how old your previous furnace was, you could experience a number of differences. Furnaces today are created to provide 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 crafted to integrate with other high-efficiency HVAC products, such as air conditioners. The air conditioner blowers give your heating system an extra lift so it can deliver cool air around your home efficiently. Special features like variable speed motors will also help lessen noise associated with operating your equipment and easily meet your family’s airflow needs. What energy efficiency standard should I look for in an air conditioner in Manassas? The Department of Energy recently increased 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 Twin Air LLC for the efficiency standards for Manassas. How can I reduce my energy costs? Heating and cooling makes up a huge portion of your monthly utility bill. Getting new HVAC equipment with high efficiency ratings, such as SEER for air conditioners and AFUE for furnaces, is a simple step that can go a long way in lowering energy output. Beyond these ratings, also think about: Routine maintenance – regularly having an expert tune-up your equipment will keep it working at its greatest potential. Adding a zoning system – by focusing your heating and cooling on the rooms you use most frequently, you won’t have to pay to heat or cool areas of your home that aren’t routinely used. Installing a programmable thermostat – the Department of Energy estimates that a programmable thermostat can reduce heating costs by up to 35 percent and cooling costs by up to 25 percent. Leave it up to your thermostat to turn down the heat when you’re away and return to your preferred temperature when you’re home. Why should I buy from Lennox?

What can I do to 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 full of with air pollutants floating around your home, so to improve IAQ, the first step is to eliminate 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 out stale air for fresh, filtered outside air. Clean – good ventilation and regular cleaning are a start, but Healthy Climate® air filters, germicidal lights and PureAire™ purification systems take your IAQ to the next level by picking up microscopic particles, killing germs and removing particles and germs while destroying chemical vapors. Monitor – programmable thermostats will help you control the humidity levels and temperature to help prevent particles and germs from building up and keep your home comfortable. How can I find out which indoor air quality product will is right 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 Twin Air LLC pros who can make a recommendation based on their evaluations of your home and your current indoor comfort system. How does an air conditioner work? You may be surprised to learn that air conditioners don’t technically make your home cooler; they actually remove the hot air and move it outside. This hot air is pushed across a refrigerant coil on the indoor unit and then is sent to the outdoor unit where it is released. Your air conditioner transfers as much hot air outside as is necessary to reach the temperature you have set on your thermostat. What is the minimum energy efficiency standard for air conditioners in my state? Different regions have different minimum energy efficiency standards. Additionally, air conditioners, heat pumps and packaged units made after Jan. 1, 2015, have higher minimum efficiency levels than HVAC products manufactured prior to that date. The team at Twin Air LLC can help you determine the minimum requirements for Manassas, let you know if your current products meets those requirements or help you find a replacement air conditioner that does. How can I confirm the model and serial numbers for my cooling unit? Your system’s service panel will have a white label on it, with your system’s model and serial numbers at the top. M/N signifies the system’s model number and S/N is the serial number. What size equipment do I need for my home? Since equipment size needs differ for each home, the best way to figure out the correct size equipment for your home is to have a technician from Twin Air LLC come out to perform load calculation tests. The tests take measurements such as square footage, insulation value and amount, and more into account to determine your home’s individual HVAC equipment needs. Can frost, ice, dirt or other debris keep the outdoor unit of my cooling system from operating effectively? Yes – debris can affect your system’s ability to function effectively. It’s normal for heat pumps to have frost or ice on them during the winter, but many include defrost controls so they can work efficiently regardless of the weather conditions. What is two-stage cooling? When a cooling systems has two-stage cooling, it means that there are two levels of operation. This lets the system work as efficiently as possible since there is one level for milder weather and one for harsher weather that demands the system work harder. Two-stage cooling also enables more even temperatures so you don’t experience extreme differences in temperature. Aside from better efficiency, other benefits of two-stage cooling include quieter operation and improved humidity control. Why is my system freezing up? When your cooling unit freezes up, there are a variety of reasons why it could be doing so. The most typical reasons include: dirty filters, low refrigerant, a dirty evaporative coil and a faulty blower motor or relay. A dirty filter is something you can fix as a homeowner, but the others need to be done by a professional like those at Twin Air LLC. Contact them at 703-754-1062 with any other questions. What is the best thermostat to use for my cooling system? Twin Air LLC carries a number of great thermostat options for your HVAC systems. The best thermostat for you will depend on variables such as whether you want one that’s programmable or not. No matter what kind of thermostat you’d like – or if you’re looking for something that can fit with a home automation system – call Twin Air LLC to hear about which thermostats you can choose from. Our team will help you find one that’s right for your system, your family’s needs and your budget. What is a heat pump? A heat pump takes care of both your home’s heating and cooling needs, offering you one HVAC system that can be used in all four seasons. In the warmer months, heat pumps act like an air conditioner, capturing the hot air from inside your home and transferring it outside; in the cooler months, this process is reversed. Heat pumps can be very energy efficient and may produce two to three times more heat than the energy used. When replacing the outdoor unit, should the indoor unit also be replaced? At Twin Air LLC, we do recommend replacing both your indoor and outdoor units at the same time because: Outdoor systems are now built to work with their matching indoor system for the highest efficiency possible. When you replace just one of your systems, you may not see the same energy savings as if you had replaced them together. Thanks to technological advancements, newer systems mean improved efficiency. This is true for HVAC products as well. While the advancements focus on greater heating and cooling efficiency, they also include benefits such as better air handling, filtering and noise reduction. If your heating and cooling systems are 10+ years old, they need to be replaced. Older models have outdated technology that is likely adding to your energy costs due to poor efficiency. So by replacing your indoor system at the same time as your outdoor equipment, both your systems will provide better energy efficiency that helps you reduce your energy bills and keep your home more comfortable. Can I see whether my solar HVAC system is performing at its maximum potential? Yes. Your SunSource® Home Energy System has a communication module that transfers the system’s performance data to a website. The website will show your system’s status, energy production and environmental benefits, as well as carbon offsets in real time. Does the SunSource® communication module need an Internet connection? Yes, you will need an Internet connection if you want to make use of the system’s online monitoring system. The system allows you to view energy production and environmental information. The monitoring service is provided at no cost for five years, and the performance-monitoring website is maintained by an independent third party, Enphase Energy Inc. Do I need to clean my solar modules? Rain will clean the modules by itself in most areas; however, if you live in a dusty area, you might see improved performance after periodically spraying the modules with water. Please note that high-pressure hoses and detergents should never be used to clean solar modules, as they can harm the product. Which thermostat is best for my home comfort system? Twin Air LLC can help you find the right thermostat for you based on your home and current heating and cooling equipment. We carry a variety of programmable and nonprogrammable thermostats, which can help increase the efficiency of your home’s furnace and/or air conditioner. Browse our thermostats or give us a call at 703-754-1062 for more information. How can I improve my energy costs? Your heating and cooling equipment can contribute significantly to your monthly energy costs. However, these costs can be reduced with innovative and high efficiency products from Lennox®. You’ll want to look for high SEER and AFUE ratings when you’re ready to purchase a new air conditioner or furnace, respectively, as higher SEER and AFUE ratings mean higher efficiency products. If you’re not looking for new heating and cooling equipment, consider factors such as: 1. Maintenance: Furnaces, air conditioners and other HVAC equipment run more efficiently when they are regularly maintained. 2. Zoning: When areas of your home are rarely used, you’re spending more money to heat or cool them to the same temperature as the rest of the house. A zoning system allows you to section off different parts of your home and control the temperature by each area. 3. Programmable Thermostats: Programmable thermostats can help you decrease your heating costs by 35 percent and your cooling costs by 25 percent, according to the U.S. Department of Energy. Why should I buy a zoning system? A zoning system allows you to parcel your house and heat or lower the temperature in each part differently. While these systems operate well for buildings that have parts that are infrequently occupied, they could also be great in situations where you and your family can’t agree on the temperature in different areas of your home. There are a number of additional bonuses of zoning systems, including efficiency and comfort.
