Frequently Asked Questions
Air Conditioning
How does an air conditioner work?
An air conditioner seems as if it cools your home’s air, but it actually makes your home less warm by removing heat from the indoor air and transferring that heat to the outdoor air.
Heat is extracted from the home by passing indoor air across a refrigerant coil in the indoor unit. Refrigerant lines then carry the heat to the outdoor unit, where it is released into the outside air. The cooling cycle continues until the indoor temperature reaches the thermostat setting.
What do all those air conditioner and heat pump ratings mean?
SEER (Seasonal Energy Efficiency Ratio) is a system for rating the efficiency of cooling equipment. The higher the SEER rating, the less your unit will cost to operate.
HSPF (Heating Seasonal Performance Factor) is a measurement similar to SEER, but it measures the efficiency of the heating portion of a heat pump.
What is two-stage cooling
Two-stage cooling means the air conditioner or heat pump has a compressor with two levels of operation: high for hot summer days and low for milder days. Since the low setting is adequate to meet household-cooling demands 80% of the time, a two-stage unit runs for longer periods and produces more even temperatures.
Longer cooling cycles also translate to quieter, more efficient operation and enhanced humidity control. Compared to a single-stage unit, a two-stage air conditioner or heat pump can remove twice as much moisture from the air. This is important because when moisture levels are high, there’s a higher potential for mold and other pollutant problems.
What size equipment do I need for my home?
The only reliable way to determine the size that best matches the needs of your home is to have a trusted Soundview Heat and Air Conditioning Corp. associate perform a load calculation, which takes into account the square footage of your house, the insulation value of your windows, the amount of insulation in your walls and roof and many other factors.
What is a heat pump?
A heat pump is an all-in-one heating and air conditioning system that works year-round to keep you comfortable.
During warmer months, a heat pump works as a normal air conditioner. It extracts heat from inside the home and transfers it to the outdoor air. In colder weather, however, the process reverses—the unit collects heat from the outdoor air and transferring it inside your home.
Even when the air outside feels extremely cold, the air still contains some heat. The heat pump pulls the heat from this cold outdoor air and sends it inside to warm your home. When there’s not enough heat in the outside air to meet the demand of the thermostat setting, an electric heater supplements the outdoor air to warm the home. Extremely efficient, this process produces two to three times more heat than the energy it uses.
Also, a heat pump can be an effective add-on option to use in conjunction with an existing gas furnace. With this dual-fuel option, the two systems share the heating load, but never function at the same time. Each system operates when it is most cost effective. The heat pump will be the primary heating and cooling system. However, when the temperature drops below the heat pump’s ability to operate as efficiently as the gas furnace, the gas furnace will take over until the temperature rises enough for the heat pump to operate more efficiently.
Why should I zone my house?
A zoning system is designed for the many ways you use your home. Maybe you’re caught up in family “thermostat wars?” Or perhaps you have unoccupied areas that do not need conditioning? A Lennox® zoning system allows you to divide your home into separate areas, giving you the comfort and control you’ve always wanted.
The main benefits of residential zoning are:
Comfort
Zoning meets the specific temperature and airflow requirements of one area, without affecting other areas.
Efficiency
A properly designed zoning system can save you hundreds of dollars in energy costs each year.
Control
Zoning divides the home into different areas and comfort into different levels, giving you more choices and control than ever before.
Quiet Performance
When integrated with variable speed and/or two-stage HVAC systems, zoning allows your heating and cooling equipment to deliver peak performance and efficiency without continually operating at peak capacity. Lower speeds mean lower sound levels.
How can I confirm the model and serial number for my cooling system?
You can find the model and serial numbers (M/N and S/N) for your furnace by removing the top-front service panel and looking to the left side of the interior cabinet or the top of the blower deck, depending on whether your system is an 80% or 90% AFUE unit. Also, the orientation (horizontal or vertical) and flow direction (down or up) of your furnace may impact the location of the information..
Why is my system freezing up?
There are several factors that can cause system freezing. Most need to be corrected by Soundview Heat and Air Conditioning Corp..
One thing you can do to prevent or correct this problem is to make sure the filter is clean or replaced. You can check to see if airflow is restricted.
Dirty filter
After replacing or cleaning the filter, you can speed up the thawing process by turning the system off and turning on the fan. If you have a heat pump system, you can try turning the system to heating mode until the ice has melted. After the ice has melted, switch the system settings back to normal. If the system refreezes, contact Soundview Heat and Air Conditioning Corp. to correct the problem.
Low refrigerant
In some cases, freezing is caused by a leak in the refrigerant lines. Weak solder joints, friction from piping rubbing or vibrating against an object, open valves or loose fittings are all factors that can cause leaks. When determining whether to have the system repaired or replaced, the age of the system and the nature and location of the leak are important considerations.
Dirty evaporator coil
Over time, the evaporator coil will become dirty. When this happens, you will begin to lose airflow, slowly enough that you probably would not realize it until it freezes up or cooling performance is compromised. At this point, you will need to contact Soundview Heat and Air Conditioning Corp. to correct the problem.
Defective blower motor or relay
A blower motor not running at the proper speed or not running at all is another factor that can cause freezing. Motor operation may be intermittent, starting at full speed and slowing down after it heats up. Or, a relay could cause it to start one time and not the next. In either case, you will need to contact Soundview Heat and Air Conditioning Corp. to correct the problem.
When replacing the outdoor unit, should the indoor unit also be replaced?
The answer is most likely YES, but this is mainly due to four main reasons:
Matched system design All outdoor cooling units are specifically designed to work with matched indoor units for optimum efficiency and performance. Air conditioner and heat pumps may “work” with other indoor units, but the result is a definite compromise in overall system performance.
Design advances In recent years, indoor blower coil units 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.
Higher cooling and heating efficiency The cooling and/or heating efficiency rating assigned to a given air conditioner or heat pump is based on matched system performance. While you may gain higher efficiency by replacing only the outdoor unit, the efficiency levels (and savings) will not be as high as with a matched system.
Equipment age If an air conditioner or heat pump outdoor unit is 10 years old and needs to be replaced, the indoor 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—you’ll have years of service from both units.
New warranty A new unit also gives you a new product warranty. Replacing the indoor unit at the same time as the outdoor unit gives you added peace of mind, knowing the new warranty covers the entire system.
Cost savings At first, replacing only an air conditioner or heat pump outdoor unit may appear to be a bargain. That is, until you consider the lower efficiency, decreased reliability and high cost of ownership associated with single-unit replacement. It may cost more to replace an entire system, but this gives you more efficiency, reliability and comfort.
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, Soundview Heat and Air Conditioning Corp. is one step ahead with a full line of products that use a more responsible, chlorine-free refrigerant.
Energy Efficiency
Should I be concerned about new energy-efficiency standards?
Heating and cooling your home can represent as much as 44% of your utility bill.* With high efficiency ratings and innovative, industry-leading technology, Lennox® home comfort systems can go a long way toward reducing these costs.
Why should I choose a Energy Star product for my home?
How can I control energy costs?
Heating and cooling your home can represent as much as 44% of your utility bill.* With high efficiency ratings and innovative, industry-leading technology, Lennox® home comfort systems can go a long way toward reducing these costs.
When selecting a new system, pay close attention to the SEER rating of the air conditioner and AFUE of the furnace. The higher the SEER or AFUE, the higher the savings.
Beyond efficiency ratings, other factors to consider are:
Maintenance You can ensure your system operates at peak performance by scheduling annual preventative maintenance checks.
Zoning A zoning system can drastically lower your heating and cooling costs. With zoning, you no longer have to pay to heat or cool areas of your home that are rarely used.
Programmable Thermostats According to the Department of Energy, a programmable thermostat can reduce your heating costs by up to 35% and cooling costs by up to 25%.

Since the low setting is adequate to meet household-cooling demands 80% of the time, a two-stage unit runs for longer periods and produces more even temperatures.
Longer cooling cycles also translate to quieter, more efficient operation and enhanced humidity control.

This is important because when moisture levels are high, there’s a higher potential for mold and other pollutant problems.
What is two-stage heating?
Two-stage heating means the furnace has two levels of heat output: high for cold winter days and low for milder days. Since the low setting is adequate to meet household-cooling demands 80% of the time, a two-stage unit runs for longer periods and provides more even heat distribution.
Longer, low-capacity operation has many advantages:
Consistent comfort Two-stage heating eliminates the temperature swings associated with standard furnaces, regulating temperature to within as little as one degree of the thermostat setting.
Quiet operation Two-stage furnaces start in the first stage, when the amount of heat required is lower, instead of reaching full capacity all at once. That means there’s no sudden “kick” or blast of air.
Improved air filtration Low-speed operation allows your filters to capture more contaminants (because air is constantly passing through them), so you can breathe easier.
Efficient performance Because the furnace operates mostly in its lower-capacity first stage, it burns less fuel than a standard furnace that always runs at full capacity and shuts off when the heating demand has been met.
Furnaces
What are furnace ratings?
Furnaces are rated by the Annual Fuel Utilization Efficiency (AFUE) ratio, which is the percent of heat produced for every dollar of fuel consumed.
Like the miles-per-gallon rating on your automobile, the higher the AFUE rating, the lower your fuel costs. All furnaces manufactured today must meet at least 78% AFUE. If your furnace is 10 – 15 years old, it very well may fall below the current furnace minimum and waste energy.
This doesn’t mean that you should only select a furnace based on its AFUE rating. The efficiency rating is just one factor to consider when looking for a new furnace.
Furnaces use electricity to run fans and motors. The amount of electricity used varies greatly depending on the type of furnace. Be sure to check electricity usage prior to making a purchase decision.
Will my new furnace work differently than my old one?
Furnace technology has advanced significantly in recent years. Modern furnaces are designed to provide more even and efficient heating than past furnaces, which can impact both how your system operates and what you notice about your system.
To better regulate temperatures and airflow, modern furnaces move more air over the heat exchanger than older furnaces. The air that comes out of your furnace registers may not seem as warm as the air from your old furnace, but overall airflow is improved. Better airflow means higher comfort.
Also, new furnaces are designed to integrate with high-efficiency air conditioners, so furnace blowers are more powerful to accommodate add-on cooling. Since cold air is much heavier than warm air, your system needs an extra boost from the blower to deliver cool air throughout your home. If you have an older home, this performance boost could produce unfamiliar sounds because air duct systems were originally designed for heating only. To minimize sound levels, choose a variable speed product which automatically changes speeds to meet the airflow needs of both heating and cooling cycles.
What is a variable speed furnace?
The term “variable speed” refers to the furnace’s indoor blower motor, which moves at different speeds to precisely control the flow of heated and cooled air throughout your home. Better airflow control has several benefits:
Electrical efficiency Variable speed motors can actually save you money on your energy bills, as they consume less electricity than standard motors.
Cooling efficiency Variable speed technology also means you will gain heating efficiency or AFUE.
Zoning Variable speed motors are excellent for zoning, which allows you to customize your comfort in different areas of your home and control your energy bills.
Air quality A variable speed motor can also help clean the air in your home. When the fan is in constant operation (indicated by the “Fan” setting on your thermostat), the motor will continue to slowly circulate air, allowing filters to capture more contaminants.
Humidity control A variable speed motor combined with a ComfortSense 7000 programmable thermostat Home Comfort Control allows you to control the amount of humidity in your home for improved indoor air quality and comfort.
Can I use my chimney with my new furnace?
Furnace technology has advanced significantly in recent years, raising concerns over chimney use. As a result of changing technology, many existing masonry chimneys aren’t able to meet the specific demands of new furnaces.
There are several reasons for this furnace-chimney incompatibility. First, the size of the chimney can be an issue. Modern, higher-efficiency furnaces transfer more heat into your home and less heat up the chimney than older, less-efficient units. While this means more efficiency for your energy dollar, it also means that the existing chimney might be too large for the new furnace. The result could be improper ventilation of flue products, which can cause condensation problems inside the chimney.
Other considerations include chimney height and location, proper lining and condition of the chimney. Building codes must also be kept in mind to ensure proper draft in the chimney for adequate ventilation.

Indoor Air Quality
Resources
Why should you keep your home’s air clean?
What causes indoor air quality problems?
Do you see what’s wrong with this picture?
Just because you can’t see the problem doesn’t mean it isn’t there.
No home is immune to indoor air quality (IAQ) problems. All homes can contain elevated concentrations of dust, dirt and chemicals. These impurities may not be visible to the naked eye. Homes can also be breeding grounds for mold and mildew.
According to the Environmental Protection Agency, the air inside the average home is up to five times more polluted than the air outside.*
Results from in-home air tests across North America support this government finding. Nearly every home (96%)** had at least one IAQ problem:
86% had high levels of particles and bioaerosols like dust, pollen and viruses
71% were filled with odors and potentially harmful chemicals and gases
46% had problems with temperature and humidity
**Source: AirAdvice 2004 field study – 10,254 tests
How to solve the problem of unhealthy air
Odors/Chemical Vapors –
(Perfumes, cleaning supplies, solvents, pet odors, cooking fumes) Airborne chemicals can cause headaches, fatigue, nausea, rashes, dizziness and, in some cases, severe illness.
Purification –
To combat toxins like chemicals, you have to destroy them. The PureAir™ air purification system safely and effectively removes and destroys chemical vapors and odors.
Ventilation –
These systems replace stale indoor air with fresh air from outside, which helps dilute the power of toxic chemicals commonly found in household furnishings.
Odors/Chemical Vapors Particles –
(Pollen, dust mites, dirt, pet dander) Airborne chemicals can cause headaches, fatigue, nausea, rashes, dizziness and, in some cases, severe illness.
Filtration –
High-efficiency filtration products are designed to capture small particles and keep them from recirculating back into your home’s air. This also helps maintain the efficiency of your HVAC system.
Humidity Control –
Products like the Humiditrol® whole-home dehumidification system help prevent moisture buildup, which can promote the growth of mold and mildew.
Bioaerosols –
(Bacteria, viruses, mold) Biological contaminants can cause or aggravate asthma, as well as hay fever and other allergies.
PureAir™ Purification System Total home comfort and peace of mind
The Mayo Clinic has found that air cleaners attached to whole-house systems are generally more effective than freestanding air cleaners. An optimal solution for central HVAC systems, the PureAir™ Air Purification System installs easily on the furnace or air handler (return air side), where a filter would typically be placed.
Unmatched cleaning power of the PureAir™ system,
compared to other technologies
Odors and chemical vapors can come from many different sources inside and outside the home. Once inside the home, these pollutants circulate through the ductwork, entering every room and living space. Using innovative air-purification technology, the PureAir System helps remove the hundreds of odors/chemical vapors that can contaminate your home’s air.

Factors to consider:
Fifty Percent Rule
When the cost of repairs approaches 50% of the value of your heating or cooling system, it’s generally time to replace the system.
Age
Even if needed repair costs aren’t quite as daunting as 50%, you might want to replace your system if it’s more than 12 years old or you’ve had a history of problems with it. Also, it might be worthwhile to take advantage of one of several opportunities:
Convenience
When you purchase a new system, you can avoid the hassle of unexpected repairs down the line, and you don’t have to sit around uncomfortable while waiting for parts.
Lower utility bills
A high-efficiency home comfort system from Lennox can save you hundreds of dollars each year in energy costs, compared to an older system.
Energy tax credits
You can recover up to 30% of the cost of select high-efficiency systems in the form of tax credits.
Enhanced comfort
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 conditioned air.
Improved air quality
Better humidity control means a reduced potential for mold and mildew growth. Lennox home comfort systems are also available with Healthy Climate® filtration, which minimizes the impact of indoor pollutants.

Finding the right system
System Matching
All air conditioners and heat pumps are specifically designed to work with matched indoor units (furnace or air handler) for optimum efficiency and performance.
While an outdoor cooling system may “work” with indoor units, including older systems, it will only operate at its peak potential when it’s paired with the right sized system for your home.
Factoring size into the equation
Bigger isn’t necessarily better when it comes to heating and cooling systems. A system that is too large for your home will frequently cycle on and off, which wastes energy. Plus, it won’t run long enough to remove humidity from the air, which can impact the comfort and health of your home.
A system that is too small can’t do its job of making you comfortable. In this case, it will run continuously to keep up with the thermostat setting, costing you more on your utility bills and potentially shortening the system’s life.
The only reliable way to determine the size that best matches the needs of your home is to have a comfort advisor perform a load calculation, which takes into account the square footage of your house, the insulation value of your windows, the amount of insulation in your walls and roof and many other factors.
