What is zoning?
Your home is the place for you to be completely comfortable. So why do you still find yourself reaching for a blanket to watch a movie? Or turning on your ceiling fan, even when the A/C is on, just to get cool after a day out in the yard? Most homes, including yours, have areas that suffer because you are asking a single thermostat located in one area to control the temperature in all parts of your home. The thermostat only knows the temperature where the thermostat is actually located! You simply cannot achieve whole home comfort with one thermostat, just like you can't (and don't want to) control all your lighting with one light switch. Zoning is a control system designed for the way you use your home. With a zoning system, each area of your home is given customized heating and cooling control. Our goal at Calverley Heating & Cooling, Inc. is to educate homeowners about the benefits of "Zoning" and demonstrate that it can be installed affordably, without disrupting your life.

Who can benefit from zoning?
While most homes can benefit from a zoning system, there are applications which frequently require zoning to correct comfort challenges.

  • Multi-story homes-The most common challenge homeowners experience with multi-story homes is called air stratification. It is when the warm air rises and cooler air falls in your home and is the most common and well recognized need for zoning. Whether it is a sweltering second floor during the summer months or a basement that is always cold, you can't stop heat from rising and cool air from falling to the lowest levels. Zoning eliminates this occurrence by pushing more concentrated air to the harder to condition spaces while closing off those which are already at a desired temperature.

  • Changing lifestyles-As peoples' lives change they tend to alter the way their home is occupied. The best examples are the empty nester, parents with a new baby or the family that welcomes an aging relative into the home. In each of these cases, not all family members share the same comfort needs or follow the same lifestyle pattern when occupying various areas of the home. For instance, temperature needs with the elderly or very young children can be more extreme and may spend the majority of their time in one area throughout the day.

  • Home additions-As you look to improve your home by adding on living spaces, you may be faced with a new set of comfort challenges. Bonus rooms, sunrooms, finished basements and other similar room additions try to force more out of the existing heating and cooling system which may be unable to accommodate the new layouts. New additions tend to be better insulated than the original home structure, causing more air to be trapped and become stagnant. Zoning helps maximize operation of your equipment while improving the indoor air quality in new spaces by constantly circulating the air.

  • Exposure to the sun- Depending on your home's design, your heating and cooling can be significantly impacted by the movement and overall exposure to the sun. As the sun moves throughout the day, it heats up certain areas, while leaving others cooler. If your thermostat is in one of the sunny areas, the room temperature will be drastically different than in the unexposed rooms. The placement and size of your windows can affect the temperature throughout your home. Rooms with many windows can quickly cool off once the sun has moved for the day, forcing your system to work harder to satisfy the difference.

Did you know that indoor Air is 2 to 5 times more polluted than outdoor air?
Most of our exposure to environmental pollutants occurs by breathing the air indoors. These pollutants come from activities, products and materials we use every day. The air in our homes, schools and offices can be 2 to 5 times more polluted, and in some cases 100 times more polluted, than outdoor air.

People Spend 90 Percent of Their Time Indoors...
Indoor air quality is a significant concern, because when the hours spent sleeping, working in offices or at school are added up, people on average spend the vast majority of their time indoors where they are repeatedly exposed to indoor air pollutants. In fact, the US Environmental Protection Agency (USEPA) estimates that the average person receives 72 percent of their chemical exposure at home, which means the very places most people consider safest paradoxically exposes them to the greatest amounts of potentially hazardous pollutants.

What Contributes to Poor Indoor Air Quality?


The primary sources of indoor exposure to airborne chemicals are products used in interior environments, including furnishings, building materials and other household and office products, that can emit thousands of volatile organic compounds (VOCs) and particles into the air. Of all the culprits that can affect IAQ, chemical emissions are the most harmful as they can contribute to a wide range of health effects.


Moisture problems are another common source of indoor air pollution as they can lead to indoor mold growth. Mold can also emit VOCs and particulates, compromising indoor air quality and leading to negative health effects. Since it is impossible to eliminate mold spores, the best way to reduce the impact of mold on indoor air quality is to prevent or promptly repair the moisture problems that enable mold growth.


The particles emitted from products such as furnishings, building materials and other household and office products are another source of indoor air pollution. Airborne particulates can also come from dirt and dust that is tracked in from outdoors. Particulates can trigger allergies and other respiratory problems in many people. Installing walk-off mats at doorways and changing air filters regularly are both good strategies to limit these pollutants.

Poor Ventilation

Most of the buildings in which people spend the majority of their time are tightly sealed and insulated to keep out unconditioned outdoor air. Furthermore, most ventilation systems are designed to bring in very little outdoor air and instead recirculate the indoor air that has already been heated or cooled. While this strategy is effective for minimizing energy costs, it can have a negative impact on indoor air quality.

REME HVAC Cell / Product Description

REME or Reflective Electro Magnetic Energy utilizes an electro magnetic energy cell to create Ionized-Hydro-Peroxides™ a friendly oxidizer plasma made from oxygen and humidity. This air purifying plasma is propelled into the HVAC duct or plenum by a silent plasma propulsion module that has no moving parts, yet propels the plasma at 2 cfm. This provides for fan or blower-less operation on a 24-hour basis. The purifying plasma will be propelled through the ducts whether the fan or blower is on or not. This permits a hardwire 110 volt plug-in installation that lets the REME run 24/7 without wiring to the fan/blower circuit.

Why go through another season with these problems when there is a solution - an Aprilaire Whole-Home Humidifier.

According to medical experts, many viruses thrive in low humidity increasing the likelihood of catching colds, flu and upper respiratory ailments. The American Society of Otolaryngology even reports that it is important to prevent an overly dry environment because it makes people more susceptible to infection.
