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, permitting your two-stage unit to run for longer periods of time. Two-stage units also offer 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 permits a furnace to adjust heat and airflow by very small amounts, as low as a 1 percent change. The system is automatic and works 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 developed to offer 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 work with other high-efficiency HVAC products, such as air conditioners. The air conditioner blowers offer 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 lessen 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 boosted 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 B & B Heating & Cooling for the efficiency standards for Florissant. How can I reduce my energy costs? Lennox has a host of HVAC products with high efficiency ratings, which can help reduce the amount of energy they require to operate. Aside from selecting 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 technician can keep your system working at its top performance. Zoning – zoning systems enable you to only heat or cool only certain 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 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 away, helping you save on heating and cooling costs. Why should I buy a Lennox product? There are many reasons to go with Lennox, but the top three are: You know and trust the name – Lennox is recognized around the world for its quality home comfort products. Innovation and high quality – Lennox is an industry leader, providing a complete line of innovative solutions for your home comfort needs.

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 full of 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, frequently 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 harder 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 routine 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 keep an eye on the humidity levels and temperature to help prevent particles and germs from accumulating 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 select details specific to your family and home and will help you find equipment best suited to meet your needs. You may also consult with B & B Heating & Cooling techs who can make a recommendation based on their evaluations of your home and current indoor comfort system. How does an air conditioner work? Lots of homeowners believe that air conditioners make it cooler in your house, but it actually removes the heat from 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 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) increased 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. B & B Heating & Cooling 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 looking 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 should be 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 choose a system is by having your local B & B Heating & Cooling 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? Yes, because dirt and other debris can impede your system’s ability to work efficiently. For heat pumps, it is common 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 warmest, the high setting is used, and when it’s cooler or more mild, the low setting gets the job done. Usually, the lower setting will take care of your cooling needs, but even when the high setting starts up, you may not realize it because it can generate such even temperatures for your comfort. This may also mean a quieter cooling system, greater efficiency and enhanced 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 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 change as a homeowner, but the others need to be done by a professional like those at B & B Heating & Cooling. Contact them at 314-838-9800 with any further questions you may have. What is the best thermostat to use for my cooling system? Identifying 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 B & B Heating & Cooling. Whether you’re in the market for 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 select from. Some thermostats will depend on what type of heating and cooling system you have, but the pros at B & B Heating & Cooling will be able to help determine what options fit your needs and your budget. What is a heat pump? Heat pumps can be a little confusing due to their name, but they actually meet 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 reversed and it collects heat from outside and brings it inside. Heat pumps are also very efficient, and may 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 intended to work with to ensure efficient performance. When they aren’t paired with the other part 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 advances most importantly include improved 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 normally need to be replaced. Not only do they consist of outdated technology, but they are also less efficient than today’s models. Adding 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 will I know if my solar HVAC system is performing to its full potential? The communication module on your SunSource® Home Energy System sends the system’s performance information 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 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 offered by an independent third party, Enphase Energy Inc., and the monitoring service is provided free for five years. Do my solar modules need to be cleaned? In most regions, rain will clean the solar modules off automatically. If you live 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. B & B Heating & Cooling sells programmable and nonprogrammable thermostats that can help enhance the efficiency of your HVAC systems. Browse our available products or contact us at 314-838-9800 to learn more. How can I control my energy expenses? Heating and cooling can make up a significant chunk of your utility costs. The innovative and high efficiency heating and cooling products available from Lennox® can help decrease these costs. If you’re searching 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. Besides purchasing a new home comfort system, consider these factors: 1. Is your product regularly maintained? Whether it’s a furnace or air conditioner, HVAC systems will work 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 parts of your house. 3. Are you using 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 equipment gives you the opportunity to divide portions of your home and control the thermostat differently in each area. Zoning equipment is ideal for when you have parts of your residence that are rarely used or when you and your family are constantly in disagreement of the perfect temperature for the house. Zoning systems are nearly silent and efficient, giving you more control over the comfort of your home. Learn more about the zoning equipment available from B & B Heating & Cooling.
