What is humidity?

Humidity is the water vapor within a given space. Absolute humidity is the weight of water vapor per unit volume. Percentage humidity is the ratio of the weight of water vapor per pound of dry air to the weight of water vapor per pound of dry air saturated at the same temperature.

Relative humidity by definition is the ratio of the mol fraction of water vapor present in the air, to the mol fraction of water vapor present in saturated air at the same temperature and barometric pressure. Approximately, it equals the ratio of the partial pressure or density, respectively, of water vapor at the same temperature.

Although there is a difference between percentage humidity and relative humidity, it is only very slight and is practically negligible at normal room temperatures. So, for our purposes, we can say that relative humidity indicates the amount that the air could hold under the same conditions.

Will my new furnace work differently than my old one?

Maybe. When you install a new indoor comfort system in your home, you’ll probably notice it operates differently than your old system. Radical changes have taken place in the technology of the comfort industry in recent years. These changes will affect how your system operates, and also may affect what you notice about your system.

HIGH EFFICIENCIES

Higher efficiencies in furnaces and air conditioners have become increasingly important over the past few years. Consumers, government agencies, and manufacturers all see higher efficiencies as a way to conserve our natural resources while reducing consumer energy costs. Today, furnaces are designed with high-efficiency in mind.

To achieve higher efficiency, new gas furnaces must move more air over the heat exchanger than older furnaces so that as much heat as possible can be sent throughout the house.

The air that comes out of your furnace registers may not seem as warm as with your old furnace, but it will heat your house just as well. In fact, better airflow can improve overall comfort by reducing air temperature differences from the ceiling to the floor, throughout your entire home.

ADD-ON AIR CONDITIONING

Modern furnaces are designed to handle high-efficiency air conditioners and must have blowers that are efficient yet powerful enough to accommodate the add-on cooling. Since cold air is much heavier than warm air, your system needs an extra boost from the blower to get cool air throughout your home to provide you with efficient total comfort during the summer.

Higher airflows required for cooling operation can contribute to unfamiliar sound levels when your new furnace is operating, because in older homes air duct systems were designed for heating only. Most Lennox products have multiple speed settings to allow for the varying air needs of both heating and cooling cycles.

YOUR NEW SYSTEM: FINE-TUNED FOR YOU

Your Lennox dealer can tell you if the changes you’ve noticed are normal when upgrading from an old, inefficient system to a new, highly efficient system. Consult your Lennox dealer to evaluate your entire heating and cooling system. Sometimes minor adjustments and modifications can be made to existing duct systems to maximize comfort and minimize sound levels.

These changes are a small price to pay for the high efficiencies that mean significantly lower fuel bills and improved total comfort!

Is there anything you can do about lingering odors?

It’s not unusual for smells to linger in a home. New carpet, fresh paint, even the fish you cooked last Thursday can be the source of unpleasant odors. Many people use scented air fresheners and deodorizers to solve the problem, but these products simply mask smells. Also, these products may contain chemicals that contribute to poor indoor air quality (IAQ). The best way to clear the air of odors and odor-causing compounds is to install a whole-house air purification system.

BETTER HEALTH

Air purification can be crucial to your health and to the health of each of your family members. Studies conducted by the U.S. Environmental Protection Agency indicate that the air inside the average home can be two to five times—and occasionally up to 100 times—more polluted than the air outside.

Pollutants can come from many places in and around your home. Chemicals in carpets, household cleaners, furniture and building materials all contribute to poor IAQ, as do dust mites, animal dander and mold. An air purification system can reduce and even destroy these potentially harmful pollutants.

CLEANER AIR

The most effective solution for controlling indoor air quality is the PureAir™ air purification system. The PureAir™ system uses patented photocatalytic technology to filter, purify and freshen the air, and it combines all these capabilities into one integrated system. For best results, combine the PureAir™ system with an ultraviolet germicidal light, which inhibits the growth of biological contaminants like mold spores and bacteria.

HOW MUCH ENERGY DOES AN AIR PURIFICATION DEVICE USE?

Lennox® air purification devices are designed to clear the air effectively and efficiently. For instance, the energy cost to operate a germicidal light is about the same as the cost of using a 40-watt light bulb.

DETERMINING IF AN AIR PURIFICATION SYSTEM IS RIGHT FOR YOU

If you are wondering whether you are in need of an air purification device for your home, you might ask yourself these questions:

Is anyone in your home particularly sensitive to strong odors, such as smoke?

Air purifiers, especially the PureAir™ air purification system, have been proven to be effective at controlling unwanted odors in the air. In fact, the PureAir™ system cleans the air in your home better than any other single system you can buy.

Do you or other members of your family have allergies or respiratory difficulties?

Mold, mildew and other airborne contaminants can cause people with allergies or asthma additional discomfort. Through the use of air purification devices, concentrations of these pollutants can be drastically reduced.

INSTALLATION AND MAINTENANCE

The PureAir air purification system and germicidal lights are fairly easy to install and maintain. Optimal solutions for central heating, ventilation and air-conditioning (HVAC) systems, these products install easily into your ductwork.

The PureAir system contains a pleated media filter that should be changed on a regular basis to prevent buildup of contaminants. It’s also equipped with ultraviolet (UV) lights that need to be replaced annually to ensure peak performance. Filters and UV lights can be obtained through your local Lennox dealer.

What can you tell me about air conditioning refrigerants?

Refrigerants are what make air conditioning possible. Contained within the coils of an air conditioning system, these agents make it possible to cool and dehumidify indoor air. Today, there are several types of refrigerants used in air-conditioning systems. The most common is R22, which will be phased out over the coming years in response to international environmental concerns. Though the transition away from R22 is just beginning, Lennox is one step ahead with a full line of products that use a more responsible, chlorine-free refrigerant.

R22. CURRENT STANDARD.

Acting in accordance with an international treaty called the Montreal Protocol, the U.S. Environmental Protection Agency (EPA) has mandated the eventual phaseout of R22 through the Clean Air Act. By 2010, the manufacturing of heating and cooling equipment using R22 will be prohibited, and by 2020 the production of R22 itself must cease.

The main reason for this regulatory action is that R22 is a hydrochlorofluorocarbon (HCFC) compound, which contains ozone-depleting chlorine.

R410A. THE REFRIGERANT OF THE FUTURE.

Many of Lennox’ newest air conditioners use the EPA-recognized, chlorine-free R410A refrigerant.
Because R410A contains no chlorine, it’s ozone responsible.

R410A is better suited for use in higher-efficiency equipment because you get a higher heat transfer rate than with R22. R410A allows

Lennox, as a manufacturer, to design and make units that are more efficient than ever, like the XC21, the world’s first 20+ SEER air conditioner. Choosing an air conditioner or heat pump with R410A not only makes sense environmentally – it may also reward you with energy cost savings.

LENNOX. LEADING THE WAY IN COOLING INNOVATION.

The introduction of cooling systems that use the latest in refrigerant technology reflects our ongoing commitment to developing innovative products that maintain a comfortable home environment, while helping preserve the global environment.

As a result of this commitment, the EPA and U.S. Department of Energy have named Lennox as an ENERGY STAR® Manufacturing Partner of the Year for the third consecutive year. Lennox is the only heating, ventilation and air conditioning (HVAC) manufacturer ever to be chosen for
this annual award.

Why should I choose a variable speed furnace for my home?

There are many reasons for choosing a variable speed furnace, but the main reason is comfort. The term “variable speed” refers to the furnace’s fan motor, which moves at different speeds to precisely control the flow of heated and cooled air throughout your home. Better airflow control means a better balance of temperature and humidity.

MORE COMFORT AND EFFICIENCY, WITH LESS SOUND

More Comfort

Variable speed home comfort systems like the Dave Lennox Signature™ Collection SLP98 and SL208V gas furnaces precisely regulate airflow to provide better control of temperature, humidity and air distribution.

More efficiency

Compared to a conventional single-speed furnace, a Lennox® variable speed furnace performs better and uses about two-thirds less electricity. During cooling operation, variable speed technology typically results in an efficiency gain of 1 SEER (Seasonal Energy Efficiency Ratio). The higher the SEER, the lower your utility bills.

Less sound

A variable speed furnace also ensures quieter operation. At Lennox, we call this SilentComfort™—a technology that combines variable speed operation with sound-reducing design. The furnace slowly ramps up to speed, so there’s no sudden “kick” or blast of air at startup.

BETTER INDOOR AIR QUALITY

Cleaner air.

When the furnace is not heating or cooling and the fan is in constant operation (indicated by the “Fan” setting on your thermostat), a Lennox variable speed furnace will continue to slowly and inexpensively circulate air throughout your home. This allows your filters to capture more contaminants (because air is constantly passing through them), so you can breathe easier.)

Enhanced humidity control.

When moisture levels are high, there’s a higher potential for mold growth and other pollutant problems. Compared to a single-speed furnace, a variable speed furnace is more effective at drawing moisture from the air for improved air quality and comfort.

HOW IT WORKS

For any furnace, providing maximum comfort means achieving the proper amount of airflow. This is true for both heating and cooling operation.

Unlike conventional single-speed motors, a variable speed motor runs at a wide range of speeds. Using intelligent technology, it continually monitors incoming data from your heating and cooling system, and it automatically makes the adjustments necessary to meet your comfort needs.

The motor varies the amount of air circulated, compensating for factors like dirty filters by increasing speed. Put simply, it delivers just the right amount of air necessary to provide the desired level of heating and cooling comfort.

Calculating Your Energy Savings

The variable speed motor will typically use only about 75 watts of power per hour, compared to a conventional blower that uses about 400 watts. Thus, over the course of one year, you can expect to save money on your electric bill with a variable speed motor.

Use this simple formula to calculate your potential energy savings, based upon your existing power costs per kilowatt-hour:

Example: 2,847 kilowatts* x $.80/kW/h = up to $240 in energy savings per year

Note: Savings are based on an HVAC system that is always operating either in heating, cooling or “Fan” mode.

*Average kilowatts saved per year is calculated by saving 325 watts of power per hour with a variable speed motor using 75 watts per hour, versus conventional blower motors using 400 watts per hour, times 8,760 hours in a year, equals 2,847,000 watts/1000, which equals 2,847 kilowatts.

Why is ventilation important for proper indoor air quality?

We were once able to achieve natural ventilation in our homes by merely opening a window. However, with the concern for energy efficiency in recent years, we have been busy making homes “tighter” from an energy standpoint. Armed with weather stripping and caulk guns, we have eliminated air leaks from our homes. Unfortunately, that has also eliminated the opportunity for outside ventilation that could help to reduce concentrations of indoor contaminants. But, thanks to some innovative engineering, it isn’t necessary to throw energy efficiency out the window in order to grab a breath of fresh air.

HOW CAN I VENTILATE MY HOME AND STILL BE ENERGY EFFICIENT?

It is now possible to exchange stale indoor air with fresh outdoor air without compromising the energy efficiency of your home. With heat recovery ventilators (HRVs) and energy recovery ventilators (ERVs), it’s out with the bad air and in with the good – all without wasting energy. HRVs and ERVs are electronically powered units that circulate air throughout your home, using the existing forced air system or specially installed ducts. The units pump stale air out of your home and replace it with an equal volume of fresh outside air. The HRV is a compact unit that conditions the temperature of the outside air, while the ERV is a packaged unit that conditions both the temperature and humidity of the outside air. Because these units condition the air before it enters the home, your energy costs remain stable.

PROVIDING FRESH AIR FOR EXCHANGE

The HRV uses virtually noise-free fans that draw in fresh cool outdoor air while it removes stale, heated indoor air. The ERV performs the same function, only utilizing a rotary energy recovery wheel. In both cases, the units transfer the temperature and moisture properties from one air stream to the other, without allowing the two airflows to mix. Both units offer easy access for change of filters and necessary maintenance, making them not only energy efficient, but easy to use.

DETERMINING IF AN HRV OR ERV IS RIGHT FOR YOU

If you’re wondering whether you need to clear the air in your home, you might ask yourself these questions:

When was your home built?

If your home is new, chances are it has been built “tighter” to be more energy efficient. This may mean concentrations of air pollutants in your home could be a concern.

Have you upgraded your home to be energy efficient?

If so, it may need an additional source of ventilation.

How often during the year can you comfortably open your windows?

Due to cold winters and hot summers, it is not always possible to have your windows open year-round. This means that you may not always have a constant controlled source of ventilation.

Do odors tend to linger in your home?

If this is the case, it is a sign of poor ventilation. There isn’t enough air being circulated throughout the home to dilute unwanted odors.

Your home comfort should include products and accessories that improve indoor air quality. Ask your Lennox dealer about the complete line of indoor air quality products from Lennox.

Why should I zone my house?

WHAT IS ZONING?

Zoning divides your home into separate comfort areas and makes your comfort equipment cool or heat only areas that need conditioning. For example, a living room with large windows may stay too hot in the summer and too cold in the winter. A zoning system will send more conditioned air to the living room, to make up for the heat gained or lost through the windows.

WHY ZONE?

Today’s families have different lifestyles and comfort needs. Maybe you have a home office that needs extra conditioning during the day, and none at night. Or you only use the upstairs bedrooms when guests visit. Whatever your needs, zoning can keep each area of your house at the perfect temperature for you and each family member.

WHEN TO INSTALL ZONING

If you are replacing your air conditioner, furnace or heat pump, it is an excellent time to install a zoning system. When your new comfort equipment is matched with a zoning system, you will have precise control in each zone. Houses that had been nearly impossible to keep comfortable are a thing of the past.

Zoning is also excellent for new homes, since it is installed during construction. If you are buying a new home, check with your builder about a zoning system. It could make the difference between enjoying your new house and being truly comfortable in it!

ZONING ALTERNATIVES

Installing more than one comfort system can work to keep temperatures comfortable, but multiple systems are expensive. Typically, in a two-story home, one comfort system is installed for the downstairs, and one for the upstairs. This way, when hot air rises, the upstairs unit can keep it cool upstairs, even in the summer. And in the winter, the downstairs unit can keep that area warm.

Zoning uses only one comfort system to control the temperature for each zone. Installing a comfort system with a zoning system costs quite a bit less than installing two systems, and the yearly maintenance is also less expensive.

HOW DOES ZONING WORK?

In almost all zoning systems, zoning is controlled by thermostats in each zone. For instance, if you have four zones in your house, you will have four thermostats. Depending on your zoning system, you may have a choice of thermostats. With separate thermostats, each zone signals the heating or cooling unit independently. This lets the system deliver cooling or heating only where it is needed. You will never have to cool or heat the whole house just to make one room comfortable.

ZONING SAVES YOU MONEY!

Zoning can drastically lower your cooling and heating bills. Zoning systems can use setback thermostats in each zone to make the most of energy savings. No more closing registers or shutting doors with each seasonal change. A good example of this is a guest room on the north side of the house. You do not want to condition it like the rest of the house, but in the winter, it needs to be kept from freezing. With zoning you can set the thermostat back, and know you are not wasting money.

Another way zoning can save money is when you are not at home. When you leave for work or vacation, you can set the whole house at an energy-saving temperature to avoid conditioning an empty house. And if you have setback thermostats, you can program them to have your living areas comfortable when you arrive home.

Lennox products have always led the way in design and performance innovation. So when you see the Lennox label, you can count on exceptional performance and reliability. And when you see the Dave Lennox signature, you know you’re getting the finest, most innovative heating, cooling and indoor air quality products available.

Why should I choose an ENERGY STAR® product for my home?

Whether you live in a warm or cold region, you’re probably feeling the pinch of high utility bills. An ENERGY STAR® qualified comfort system can help you cut energy costs and save hundreds of dollars every year.

A GOOD SIGN

ENERGY STAR is a U.S. government- sponsored program that helps businesses and homeowners save energy and protect the environment by giving them the information they need to make smart choices about efficiency. A key component of this program is the ENERGY STAR label,
which recognizes excellence in energy-efficient performance.

BRILLIANT SAVINGS

One of the strongest reasons for choosing an ENERGY STAR-labeled product over a conventional model is that it can deliver significant savings. An ENERGY STAR furnace can reduce your heating costs by as much as 40%.1 And an ENERGY STAR air conditioner can save
you up to 50% on your cooling bills.1 Proper sizing and installation of equipment is critical to achieve optimal performance. Split system air conditioners and heat pumps must be matched with appropriate coil components to meet ENERGY STAR® criteria. Ask your Lennox dealer for details or visit www.energystar.gov.

Given that average household heating and cooling costs amount to about $600 a year (nearly half of your home’s total energy bill),2 it makes sense to choose a higher-efficiency system.

EXTRA CREDIT

If you install a new ENERGY STAR heating or cooling system, you may qualify for a federal tax credit of up to $500.3 You may also be eligible for utility rebates in your area.

CLEANER GLOBAL ENVIRONMENT

By creating a more efficient home environment, you are contributing to a cleaner global environment. According
to the EPA,4 if just one in ten households installed ENERGY STAR heating and cooling products, the change would keep more than 17 billion pounds of pollution out of the air.

MORE COMFORTABLE HOME ENVIRONMENT

Advanced technologies that improve energy efficiency also enhance your comfort, so you can enjoy more even temperatures, better humidity control and a constant flow of warm air. Lennox® high-efficiency home comfort systems are designed with the finest features available, so you get the best of all worlds.

For three years in a row, Lennox has been named an ENERGY STAR Partner of the Year. Lennox is the first and only heating, ventilation and air-conditioning (HVAC) manufacturer to receive this prestigious award, which reflects our ongoing commitment to
making and selling energy-efficient solutions that save money and help protect the environment.

What is a heat pump?

A heat pump is an efficient method of cooling your home in summer and warming it in winter.

WHY SHOULD I CHOOSE A NEW HEAT PUMP?

A new energy-efficient heat pump is a good investment, providing years of worry-free heating and cooling and significant year-round savings on your utility bill.

HOW A HEAT PUMP WORKS

A heat pump works by moving heat. In the summer, a heat pump collects heat from the air inside your home and expels it outside, just like a standard air conditioner.

In the winter, the process is reversed, collecting heat from the air outdoors to provide warm air inside your home.

HOW DOES IT WORK IN THE WINTER?

“You’re saying that when it’s 38 degrees outside, my heat pump can still take enough heat out of the air to warm my home?” Right. Even the coldest winter air contains some heat. It is not uncommon to use a modern heat pump on days when the temperature is near or below freezing (32 degrees Fahrenheit).

When it is too cold for a heat pump to keep you comfortable, a backup source of heat is often used, such as electric resistance heat strips or a gas furnace.

HOW WELL DOES IT WORK

While many people find the winter operation of a heat pump the most difficult to understand, it is during the heating cycle that the heat pump produces the most significant savings.

Unlike a furnace that turns fossil fuel or electricity into heat, the heat pump collects heat that already exists in the outdoor air by means of its refrigeration cycle. Consequently, your heat pump will produce two to three times more heat than the energy it uses!

HOW MUCH MONEY CAN I SAVE?

Savings depends on these factors:

  • The efficiency of your old equipment
  • The efficiency of your new heat pump
  • Your climate
  • Your electric rate

SAVE ON COOLING!

Cooling efficiency is rated by SEER (Seasonal Energy Efficiency Ratio). The higher the SEER, the higher the savings. If your home is over eight years old, your current air conditioner or heat pump probably has a SEER of 10.00 or lower. A new, higher efficiency heat pump can be as much as 56% more efficient.

SAVE ON HEATING!

Heat pumps are rated for heating efficiency by HSPF (Heating Seasonal Performance Factor). Heat pumps are available with HSPF ratings up to 9.70. Since a heat pump is more efficient than other forms of heating, the coefficient of performance (COP) is often more than one. This means, you may pay for a dollar’s worth of electricity, but a heat pump can deliver as much as $3.45 worth of heating. That’s quite a bargain!

DUEL-FUEL

If you’re looking for a new cooling system, but your old gas or oil furnace is still working, consider buying an add-on heat pump. With a dual-fuel system, the two systems share the heating load, but never at the same time. Each system operates when it is the most cost effective.

In a dual-fuel system, the heat pump will be your cooling system in the summer and your primary heat source in winter. But when the temperature drops below the heat pump’s set point, your furnace will take over until the outside temperature rises enough for the heat pump to operate more efficiently than your furnace.

To find out what high-efficiency Lennox heat pumps can do for you, call your local Lennox Dealer.

Why should I choose a whole-home dehumidifier for my home?

High humidity can make the air feel warmer than its actual temperature. Plus, it can make your home a breeding ground for pests and mold. Fortunately, we have a solution that can help.

The Humiditrol® whole-home dehumidifier system works with your central heating and cooling system to manage moisture levels in every room, so you can enjoy greater comfort and better indoor air quality.

What’s the advantage of two-stage heating?

Two-stage technology allows furnaces to automatically adjust heating output to maintain consistent comfort throughout your home. More consistent airflow also results in quieter operation and enhanced indoor air quality.

WHY TWO STAGES ARE BETTER THAN ONE

Do you sometimes find it challenging to obtain the ideal temperature within your home during winter months? First, it’s cold, so you turn up the thermostat, which starts the furnace. Then, it’s so hot you turn it down again.

Traditional furnaces are designed to operate only at one level – high. No matter what the temperature is outside, they run at full capacity.

Furnaces with advanced two-stage technology make the distinction between mild and extreme weather, delivering the level of heating output necessary to maintain optimal comfort conditions inside your home.

A two-stage furnace starts in first stage, operating at about 68% of its heating capacity. This reduced capacity is sufficient to keep your home comfortable when the weather outside is mild. Should the temperature suddenly drop, the unit automatically adjusts to high output (second stage) to meet the comfort demands of your home. It’s like having two furnaces for the price of one, and you don’t have the hassle of constantly adjusting your thermostat.

When replacing the outdoor unit of an air conditioner or heat pump, should the indoor unit also be replaced?

The answer is YES, and here are the reasons why!

MATCHED SYSTEM DESIGN

All outdoor air conditioner and heat pump units are specifically designed to work with matched indoor units for optimum efficiency and performance. The result of this matched system is a coordinated, top-performance combination that ensures the dependability and high efficiency today’s applications require.

Outdoor air conditioner and heat pump units may “work” with indoor units other than those for which they have been specifically designed; however, the result is a definite compromise in system performance.

HIGHER COOLING AND HEATING EFFICIENCY

The cooling and/or heating efficiency ratings that are advertised for an air conditioner or heat pump are based on their performance as part of a matched system.

Although a mismatched system may work, it won’t work as well as it should and costly components like the compressor could fail prematurely. Investing in a complete matched system offers many benefits. Not only will you enjoy lower energy usage due to higher efficiency, you’ll also find that a matched system lasts longer because all the components operate as they were designed to, thereby protecting your investment.

DESIGN ADVANCES

Through the years, indoor air handlers have undergone numerous design advances – especially in the areas of air handling performance, filtering efficiency and operating sound levels. A new outdoor unit will also include the latest design advances.

EQUIPMENT AGE

If an air conditioner or heat pump is 10 years old and needs to be replaced, the indoor air handler unit is just as old and has been subjected to the same amount of wear and tear. Replacing both units means you won’t have to replace the indoor unit in a short time.

NEW WARRANTY*

A new unit also gives you a new product warranty. Replacing the indoor unit at the same time as the outdoor unit results in peace of mind, knowing the new warranty covers the entire system.*

A BARGAIN?

At first glance, replacing only an air conditioner or heat pump outdoor unit may appear to be a bargain. But when you consider the lower cooling and heating efficiencies, decreased reliability and the high cost of ownership that results, it’s not such a bargain after all!

Replacing an entire air conditioner or heat pump system costs more initially, but you get more…efficiency, reliability and comfort.
