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 set on the low setting, allowing 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? 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 works 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 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 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 Mount Pleasant? The Department of Energy recently boosted the minimum efficiency levels for air conditioners, heat pumps and packaged units created after Jan. 1, 2015, since heating and cooling contributes significantly to a home’s total energy usage. The requirements vary by region, so call Olde Towne Heating & Air for the efficiency standards for Mount Pleasant. How can I reduce my energy costs? Lennox has a variety of HVAC products with high efficiency ratings, which can help reduce 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 – ensuring your system gets regular maintenance by a trained expert can keep your system running at its top performance. Zoning – zoning systems permit 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 don’t usually use. 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 from Lennox? There are a number of reasons to go with Lennox, but the top three are: You know and trust the name – Lennox is well-known around the world for its quality home comfort products.

What can I do to improve my home’s indoor air quality? Boosting 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, regularly 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 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 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 Olde Towne Heating & Air experts who can make a recommendation based on their evaluations of your home and your 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 inside your home, moving 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 cycle 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 high 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 by region and carry varying requirements based on your location. Olde Towne Heating & Air 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 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 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 is right for your home, but the most reliable way to determine the right size system is by having your local Olde Towne Heating & Air 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 are built with 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 starts up, and when it’s cooler or more mild, the low setting handles the duties. Most of the time, 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 may also mean a quieter cooling system, greater efficiency and enhanced humidity control. Why is my system freezing up? When your cooling unit freezes up, there are a couple 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 Olde Towne Heating & Air. Contact them at 843-856-1433 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 wide variety of choices from Olde Towne Heating & Air. 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 choose from. Some thermostats will depend on what type of heating and cooling system you have, but the pros at Olde Towne Heating & Air 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 bit confusing due to their name, but they actually take care of 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 could 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 unit as a complete system, efficiency can suffer. As with many products, advancements have brought about newer, more efficient ways of doing things. Heating and cooling systems are no different. These improvements most importantly include better 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 feature 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 data for each module to a website. You can go to this website to view the system’s status, energy production and environmental benefits. The site also shows carbon offsets as it happens. Do 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 accessing 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 at no cost for five years. Should I clean my solar modules? In most regions, 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 clean solar modules. What is the best thermostat for my HVAC system? The proper thermostat for you depends on your heating and cooling equipment. Olde Towne Heating & Air has programmable and nonprogrammable thermostats that can help enhance the efficiency of your HVAC systems. View our available products or contact us at 843-856-1433 to learn more. How can I control my energy costs? Heating and cooling can contribute to a significant amount of your utility costs. The innovative and high efficiency HVAC products available from Lennox® can help lower 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 system 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 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 spaces of your house. 3. Are you using a programmable thermostat? According to the U.S. Department of Energy, programmable thermostats can 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 your home allows you you the opportunity to divide portions of your house and control the air differently in each room. Zoning equipment is best for when you have spaces of your home that are seldom used or when you and your family are always in disagreement of how hot or cold it ought to be inside. Zoning systems are quiet and efficient, allowing you more control over the comfort of your family home. Find out more about the zoning systems available from Olde Towne Heating & Air.
