Healthier Homes Using Air to Air Exchange Systems Can your own home be making you sick? The overall performance and indoor air quality of any home is dependent upon its ability to function properly. Homes of today are uniquely designed with energy efficiency in mind. Hence, the structure becomes much tighter raising serious indoor air quality, comfort and structural concerns. Indoor Air Quality Ventilation and Moisture Control Newer construction methods can improve air tightness conflicting with the ability of your home to function properly. Air flow, ventilation, temperature control, air filtration, dust (mites) problems and more are very serious concerns for the health of your family. Question: Can your own home be making you sick? Answer: Yes. Indoor Air Quality. Any structure must have the ability to breathe by mechanical means and function as a complete system. Any building structure is composed of a wide variety of manmade, natural building materials and components that need to function in harmony during our adverse weather conditions throughout the year. Moisture problems can lead to significant health problems and indoor air quality concerns of its occupants. Structural dry rot or overall weakness can derive from the inability of the structure to prevent or move moisture away from the home. Major respiratory ailments can develop from these unhealthy conditions, especially in the elderly and young infants. Indoor Air Quality concerns include a lack of ventilation which can be a contributing factor from within our homes as a major contributor of Sick Building Syndrome (SBS).  PDF version Inadequate ventilation is very common in many homes which can lead to mold growth and other respiratory ailments causing Indoor Air Quality issues. There are more than 100,000 species of molds. Over 1,000 different molds are found in the United States. Some common molds found are species of Cladosporium, Aspergillus, Penicillium and Alternaria. These molds produce airborne toxins called Mycotoxins which can cause very serious breathing difficulties, memory and hearing loss, dizziness, flu like symptoms and possible bleeding of the lungs possibly related to our indoor air quality. Many other indoor air quality symptoms may include running nose, eye irritation, chronic cough, congestion, severe respiratory problems and aggravation of asthma. Common molds can be toxic and sometimes lethal for individuals with weakened immune systems. A 1996 Mayo Clinic study had linked chronic sinus infections afflicting over 37 million people to molds. Radon, The Invisible Intruder, effecting our indoor air quality can be lethal effecting an estimated 20,000 people per year. Ranked #2, and a known leading cause of Lung Cancer in the United States. There are many causes for alarm that can be related to our indoor air quality and this disease to include much tighter surroundings within our own indoor living environments. As we spend up to 90% of our time indoors, the air we breathe, as much as 200,000 liters per day, can be related to our indoor air quality and contains microbiological and solid airborne submicroscopic particulates that can be dangerous and very harmful to our immune system especially in young infants. Over 90% of these harmful particulates are less in size than .03 microns. One micron is 100 times less than a human hair follicle. Most filters generally capture less than 10% its required rate of filtration and are very restrictive to air flow, which can therefore increase energy costs and reduce heating and cooling performance. Penetration into structures from cracks, non-existent moisture barriers and weakened foundations may increase the risk of radon and affecting our indoor air quality. This poisonous gas is now the leading cause of lung cancer in the United States. Second-Hand smoke can also cause severe respiratory...

Minnesota Heat Pump Systems Repair & Installation Heat pumps efficiently heat your home in winter and cool your home in summer. During winter, an electric or gas furnace supplements your heat pump by providing the additional heat needed to keep you comfortable when outside temperatures are low. As your heating system ages, it can lose efficiency or stop working altogether. With the cost of home heating fuel constantly on the rise, there’s never been a better time to explore alternative means of controlling temperature in your home. Heat and Cool Your Home Efficiently Heat pumps have been now increasingly used as an efficient, convenient and cost effective alternative to heat and cool indoors from a single unit. In fact, the installation of a heat pump is a long term investment. It is therefore vital to undertake a thorough research, prior to its purchase. These are some important factors that should be taken into account while purchasing a heat pump. First, compare the efficiency ratings such as SEER and HSPF of different heat pumps now available in the market. The higher the SEER and HSPF ratings, the more efficient the functioning of your heat pump will be. The SEER (Seasonal Energy Efficiency Ratio) is used to rate its cooling efficiency while the HSPF (Heating Seasonal Performance Factor) serves as a way to measure the efficiency of heat pump’s compressor. A reliable heat pump will usually have a SEER rating ranging from 14 to 19. When it comes to HSPF, it will be mostly between 8 and 10. Another important factor that should be considered for the right selection of heat pump is to check whether it is environmental friendly. For best results, opt for a heat pump with ozone friendly refrigerant, R410a. Equally important is to review its unique features. It would be a good option to choose a heat pump with features like two stage compressors as well as motors, and scroll compressor that help for its quieter performance. Further, make sure that your chosen heat pump is covered by excellent warranty options. The EPA has mandated that manufacturers stop making R-22 equipment (that is most likely the refrigerant your current system uses).  This means that if you make a major repair to your existing system, you have made an investment in a piece of equipment that is no longer going to be manufactured after 2009. New systems are installed with R-410a, which is the new refrigerant being used by manufacturers.  This refrigerant is more environmentally friendly than R-22, its predecessor. Because these units provide both heating and cooling, it is even more important that you have the proper size. The wrong size unit will steal money from your pocket the whole year long. That can add up in a hurry! A heat pump’s heating and cooling capacity should match your home’s heating and cooling demands to work most efficiently. An undersized system won’t adequately cool your home, while an oversized one won’t dehumidify properly and can make the house feel drafty in the winter. Ask a licensed Minnesota heating and air conditioning contractor for a heating and cooling load system analysis. With any major repair on your furnace and air conditioner that is older than eight years, you investing money into an old system, there are no guarantees that something else won’t fail in the near...

MN Heating And Cooling Systems Minneapolis MN Indoor air quality is important. We breathe about 5,000 gallons of air daily. Indoor air can be more polluted than outdoor air, even in large industrialized cities. We spend 90% of our time indoors. Especially at risk are infants and the elderly, who spend almost all of their time indoors. Indoor pollution can be as serious as carbon monoxide poisoning, which can be life threatening. Excessive moisture inside the home can also contribute to indoor air contamination. Keep Your Home Healthy Reduce your exposure to indoor pollutants It’s best to focus on changes you can take to reduce your exposure to indoor pollutants. Heat Recovery Ventilation Ventilation can be provided by natural airflow through doors and windows. A heat exchanger (heat or energy recovery ventilator) is an efficient and economical way to have air exchanged and yet reduce heating and cooling costs. Heat exchangers require maintenance to be efficient and effective. Optimum Relative Humidity Moisture levels need to be monitored. Too much moisture can cause damage to a home and affect health. Molds and viruses multiply with too much moisture in the home. At low relative humidity, incidents of respiratory infections and allergic rhinitis increase. Other concerns of low humidity are static electricity, damage to furniture and musical instruments, and dry skin. Controlling Excess Moisture Use exhaust fans when showering Repair plumbing leaks Vent clothes dryer Dry and clean flooded materials People produce 3 pints of water per day just breathing. Other sources of moisture include cooking, cleaning and taking showers. About one pint of moisture comes from a 10-minute shower. Moisture coming from basement walls and floors can be up to 100 pints per day with wet soil. Removing Moisture Ventilate in cold weather Dehumidify or air condition in warm weather Relative humidity is the amount of moisture in the air relative to the amount it can hold. Cold air can hold very little moisture, so even at 90% RH there is little moisture in the air. As the air is warmed, the amount of moisture it can hold increases and the RH decreases. Air at 0°F and 90% RH will have a RH of only 5% when warmed to 70°F. Since outside air is very dry during the winter, ventilating is the best way to remove moisture. Summer ventilation may increase the humidity in a basement. Cooling air increases its relative humidity. Air at 75°F and 65% RH will have a relative humidity of about 90% if cooled to 65°F in a cool basement. A dehumidifier or air conditioner is recommended to reduce basement humidity during the summer. Reduce Condensation Winter — 30-40% humidity Summer –less than 65-70% humidity Even with energy efficient windows, relative humidity in the home or in one room can cause condensation on windows. Prolonged moisture from condensation can damage the window by rotting wood around the window and lead to mold growth. Reduce condensation by keeping the indoor humidity level below 40% in winter. You can reduce window condensation by adding an additional layer, such as plastic, which warms the window surface. This is similar to dressing in layers. Dehumidifiers generally only lower humidity to about 50% so dehumidifiers are not adequate for limiting condensation during the winter. Hygrometer Hygrometers measure relative humidity but are often not accurate. Some can be as much as 20% off. Electronic digital units tend to be more accurate. To calibrate, place the hygrometer in a sealed plastic bag with a mixture of 1/4 cup table salt and 1/2 cup water for 12 hours. The gauge should read 75% humidity....

Heat Pump Installation Minneapolis MN | Install Heat Pumps Heat Pumps are a great way to heat your home that draws heat from the air outside your house, just as an air conditioner does.  Heat pumps are the ideal solution for Minnesota climates, where half the year we need heat pumped into our homes and during summer months we need heat extracted out of our homes.  Heat pumps can meet all your cooling and heating needs in one single system, unlike most conventional air conditioning systems that only provide cooling at high costs. Heat Pumps Are Perfect For Minnesota Climates A heat pump is an all in one heating and cooling system.  Heat Pumps Defined: Here’s how Wikipedia describes them: “A heat pump is a machine or device that moves heat from one location (the ‘source’) to another location (the ‘sink’ or ‘heat sink’), using work. Most heat pump technology moves heat from a low temperature ‘heat source to a higher temperature heat sink. Common examples are food refrigerators and freezers, air conditioners, and reversible-cycle heat pumps for providing thermal comfort.” Heat pumps operate most efficiently when outside temperatures range between 30 and 65 degrees. That’s typical of fall and spring weather here in Minnesota, so heat pump technology is ideal for those seasons. When temperatures drop below 30 degrees, your furnace system automatically takes over. A heat pump works as a very efficient air conditioner, in hot weather, with SEER ratings up to 19, and is much more efficient than your furnace to heat your home in cool weather. It’s an ideal hybrid system that helps you make the most of your energy budget and keeps your home even more comfortable. Heat Pumps For Cooling During summer months it works like an air conditioner. They are designed to take heat from inside your home and transfer it to the outdoors. Even on the hottest summer days heat pumps provide maximum cooling while maintaining the highest level of efficiency and comfort. Heat Pump For Heating Heat Pumps will also heat your home when the weather is cooler, it does the exact opposite, extracting heat from outside and moving it indoors. Now that might sound a bit strange to anyone other than a certified Heating Ventilation and Air Conditioning (HVAC) Contractor.  After all, how can you find heat outdoors in the winter, right?  Imagine that you took a window air conditioner and flipped it around so that the hot coils would be on the inside of your house and the cold coils would be outside. Now reverse your fan so it blows inside again and you would have a heater. It turns out that this heater works extremely well. Rather than burning a fuel, it is moving heat from outdoors and “pumping” it inside. Heat pumps combined with a gas furnace, it creates a dual-fuel system providing optimal comfort and efficiency. By adding it to your gas furnace it will allow the option of electricity-fueled heating and cooling, in addition to gas furnace heat. When heat pumps are added to gas furnaces it is known as “hybrid heating” or “hybrid heat”. Consider installing a new heat pump when designing your heating and cooling system to cut your heating and cooling costs significantly.

HVAC Ductwork Installation Minneapolis St Paul MN Thinking about that cold air blowing into your home? Fed up with air leakage coming from doors, windows and floors? Concerned about CO levels or the possibility of a furnace failure? A home performance analysis is the best way to find out how safe your home is and how well it’s being cooled, heated and ventilated. The quality of the air we breathe indoors has become an increasingly important environmental concern. Following are facts that have been determined by recognized authorities in the fields of health and air quality: Air Quality and Your Family’s Health Most people spend 60% to 90% of their time indoors. (American Lung Association) 20% of all illnesses are either caused by, or aggravated by, polluted indoor air. (American College of Allergists) The levels of some hazardous pollutants in indoor air has been found to be up to 70 times greater than in outdoor air. (USEPA) Studies have shown that two out of three indoor air quality problems involve the HVAC/Air Duct System. More than 50 million Americans suffer from allergies. One out of six people who suffer from allergies do so because of the direct relationship to fungi and bacteria in air duct systems. (Total Health and Better Health Magazines) 10-12 million Americans suffer from Asthma. (American College of Allergists) Children and the elderly are especially affected by polluted indoor air. (Department of Consumer Affairs) Most commercially available fiberglass furnace filters are less than 7% efficient. (ASHRAE) Protect Your Home & Your Health Also, poorly installed or corroded ductwork can account for up to 30 percent of your heating and cooling costs, costing hundreds if not thousands of dollars, depending on the size of your residence or building. Whether you need ductwork service or installation, contact an experienced MN Cooling, Ventilation & Heating...

Air Exchanger Systems, Energy Recovery Ventilators and Indoor Air Quality This type of ventilation is a mechanical process in which the entire volume of stale air confined within a dwelling is exhausted to the outdoors, while fresh air is supplied back into the building. In many new homes, moisture trapped from within the building wall cavity may cause excessive moisture, therefore causing possible decay and structural rot. Other hazards may include possible internal depressurization and back-drafting of the building. This condition can cause dangerous levels of carbon monoxide to elevate within the home. It is highly recommended that any excess relative humidity is removed from the home by an air exchanger. Other concerns are homes that have been super-insulated beyond the required minimal standards by local code, excessive air tightness, lack of moisture prevention during the construction process, poor attic ventilation and minimal moisture barriers. How Does an Air-to-Air Heat Recovery Ventilator Work? Air Exchangers provide an effective means of ventilation for your home. There are several types of applications for your home. A typical installation usually occurs in the mechanical room near the furnace. HRV or (Heat Recovery Ventilator) are most beneficial in colder climates by recovering over 70% of sensible heat from indoor air. As the exhaust air passes through the heat recovery core, heat from the indoor air stream is transferred with fresh air back into the home. ERV or (Energy Recovery Ventilator) systems can recover additional heat, due to the latent heat of moisture removal from the air stream. These systems are very effective in warmer, more humid climates. Air Exchangers can provide continuous ventilation and moisture control for your home. Overall performance and health of your home is dependent on proper ventilation, humidification and precision temperature control. The design and application is essential in building function and system operation. Air Exchangers are a cost effective and efficient means of improving indoor air quality. Typical applications include residential homes, indoor pools, health clubs, smoking rooms, dental offices, beauty salons, automotive stations and much more. Moisture control is essential in maintaining a healthy indoor environment. Energy-efficient operation lowers operating costs. Annual electrical consumption of less than 2 amps is comparable to a 100 watt light bulb. Application may include pre-heat accessories, control modulation and duct fabrication. Benefits Of Air Exchangers If you have allergies or respiratory problems, you know the importance of fresh outdoor air.  Being in an air-tight home or office can cause some problems for people with these health issues.  Long Minnesota winters do not make it easier.  According to the EPA, studies have shown that air within homes can be more seriously polluted then even the most industrial cities.  With some people spending approximately 90% of their time indoors, they are more susceptible to the effects of indoor air pollution. Proper ventilation with an air exchanger could help. Even if your home is older and not tightly insulated, it is likely that in the winter, the air inside your home gets stale.  Air exchangers can help bring fresh outdoor air inside the home, while exhausting an equal amount of stale air, providing a healthy balance to your ventilation system. Air Exchange Ventilator (AEV) Benefits: Reduce excess humidity which can cause mold, mildew and deterioration to your home Reduce dangerous pollutant fumes or gases Remove particles like dust and dander Help reduce heating and cooling costs for highly insulated homes Remove “stuffiness” and help freshen up the home Air exchangers (also known as heat recovery ventilators or air-to-air heat exchangers) can be used in conjunction with your other residential or commercial HVAC equipment, such...
