Hardware Store Dehumidifiers "Yeah I got one of those hardware store standalones. They work great for about 18 months and then crap out. I've been tallying my costs and after almost 4 years I'm coming up on the cost of a professional grade unit anyway. I should've just grabbed one of those in the first place." ​ Time and time again we hear the same concept: I wanted to save money. A good thought, but as I am sure you're well aware: not always an easy thing to do. Buying a simple dehumidifier from the hardware depot will certainly save you some cash up front, but costs add up and you get what you pay for. ​ If you're fed up with paying out for lesser goods, then consider a Santa Fe Dehumidifier. They recently merged Ultra-Aire into their line-up and their options for standalone or whole-house dehumidification are looking great. Santa Fe Made in the U.S.A. by the same folks who make top trusted commercial brands like Quest and Phoenix; Therma-Stor has been making top-of-the-line Santa Fe Ventilating Dehumidifiers since 1977. ​ They also offer warranties that are unmatched in the industry. No other manufacturer comes close to matching it. After all, when you build a quality product, you’re not afraid to stand behind it. Ventilating Dehumidifiers...? Oh yeah, they exist. Taken directly from the manufacturer's website : ​ "A whole house ventilating dehumidifier is a dehumidifier designed to work with the home’s HVAC system to bring in outdoor air, which improves air quality by diluting indoor contaminates, all while dehumidifying the entire home to maintain a set relative humidity (RH) level. Santa Fe is the only manufacturer to offer a complete line of whole house ventilating dehumidifiers that are energy efficient and offer superior MERV-13 filtration." ​ While a common application in some areas of the U.S., you do not need to have a full HVAC system to take advantage of the benefits of fresh air. How do I get one? If you'd like us to deliver the unit, hang it and potentially run some duct work; you can fill out our dehumidifier estimate request or- if you're more of a DIYer -we can provide you with the unit, hanging kit and controller options from our office in Gray, ME. It's best to order a week or two in advance, due to CoViD supply isn't always immediate, though we do try to keep a few of the most common (Ultra70 ) in stock. ​ Give us a call or order one directly from our online store if you prefer.

Ventilation & IAQ - FAQs Are the contents of indoor air really that bad? Maine residents face exposures: Radon Formaldehyde Carbon monoxide Lead Asbestos Mercury Pesticides Chemicals Tobacco products ​ That's not including biological contaminants such as: Viruses Bacteria Molds Dust mites Allergens On top of that, all of these are trapped in the air we “re-breath”. ​ In our attempts to be energy efficient, we live in tightly sealed homes for up to 8 months a year. The tighter the construction, the greater the concentration of these pollutants – and our bedrooms are the worst! ​ These pollutants can have an affect on your quality of life and daily tasks and routines. Read Ventilation Rates and Office Work Performance for more information. ​ ​ But I'm healthy, am I really at risk? Certainly kids and seniors are most at-risk, however, indoor air pollution can effect you in a variety of ways. Eye irritation, morning grogginess, fatigue, dizziness, diminished ability to concentrate, headaches, runny noses, irritated throat and lungs are issues regardless of your age. Breathing dirty, mold/bacterial laden air for long periods of time can affect any part of your body, including, lungs, heart, liver, kidneys, brain and nervous system. According to the EPA, indoor air can be up to five times more contaminated than outside air and sometimes even higher. ​ ​ What is Sick Building Syndrome? From the EPA "The term "sick building syndrome" (SBS) is used to describe situations in which building occupants experience acute health and comfort effects that appear to be linked to time spent in a building, but no specific illness or cause can be identified. The complaints may be localized in a particular room or zone, or may be widespread throughout the building. In contrast, the term "building related illness" (BRI) is used when symptoms of diagnosable illness are identified and can be attributed directly to airborne building contaminants." ​ [Signs] of SBS may include: Building occupants complain of symptoms associated with acute discomfort, e.g., headache; eye, nose, or throat irritation; dry cough; dry or itchy skin; dizziness and nausea; difficulty in concentrating; fatigue; and sensitivity to odors. The cause of the symptoms is not known. Most of the complainants report relief soon after leaving the building. ​ ​ What can cause SBS? There are a number of potential causes which the EPA has kindly collected and presented here: https://www.epa.gov/sites/production/files/2014-08/documents/sick_building_factsheet.pdf ​ There seems to be a lot of moisture in my home, is that bad? Mold spores are just waiting for enough moisture to start growing. Mold uses the cellulose in wood fiber as a food source – this is how dead trees disappear in the woods. The outbreak of Legionnaires Disease demonstrated just how deadly mold can be. There are a number of ways that excess moisture occurs in a home, and reducing them is a good step forward to helping reduce this issue. Some of these examples are: ​ Plumbing and roof leaks Cooking without a range hood Showering without properly venting the steam (bath fan or ventilation system) Larger families or homes with multiple large animals Humidifiers Improperly vented clothes dryers Drying clothes on an indoor drying rack or line drying indoors Flooding and sewer backups Poorly maintained gutters, downspouts and drains Water seeping into the basement without proper drainage Open and/or unvented crawl spaces ​ With so many problems, I'll just get an air purifier! That will fix my air, right? There are 3 main types of air pollution: particles, gases and moisture. Most room air filters only filter out particles. The gases may be the biggest threat to our health. A filter will do nothing for moisture and depending on the type of unit, likely will not help with gases. They also do just a relatively small area: one room. So to help with the whole house, you would have to get one for each room. Air purifiers do not effectively aid in the reduction of radon in the air. ​ ​ ​ ​ ​ So is Radon really that much of an issue? Radon is an odorless, naturally occurring gas produced from the decay of uranium in the ground. It has a high statistical correlation to lung cancer for people who have never smoked. Here in Maine, the problem is serious. In residences tested, from 44% to 74% of the homes (depending on the county) produced levels high enough to require remediation. According to recent CDC reports, Maine has a Lung Cancer death rate 20% higher then the national average. ​ Radon is the number one cause of lung cancer among non-smokers, according to EPA estimates. Overall, radon is the second leading cause of lung cancer. Radon is responsible for about 21,000 lung cancer deaths [in the U.S.] every year. About 2,900 of these deaths occur among people who have never smoked. ​ ​ ​ What if I don’t want the system running all the time? Since our focus is to improve the overall health of occupants like heating your home, our recommendation is to run the system while the home is expected to be lived in. Main controllers always include the option to turn the unit off, whereas others have a manual on/off button on the unit itself. ​ Won’t we lose heat if we are constantly bringing in fresh cold air? Yes. You will lose some heat. This is why we are tightening up our homes. The truth is, you already are losing heat energy by running the bath fan, clothes dryer, range hood, or any other movement of warm air from inside to the outside. The difference is that with a mechanical ventilation system, you can control the air flow. Energy recovery ventilation systems provide a way of ventilating a home while minimizing energy loss. They reduce the costs of heating ventilated air in the winter by transferring heat from the warm inside exhaust air to the fresh (but cold) outside supply air. In the summer, the inside air cools the warmer supply air to reduce cooling costs. A better question is whether we can stay healthy and avoid health care costs by ventilating out harmful pollutants!! Because of the health care burden of our houses, the Government is making steps to address this issue. ​ If my system is on all the time, how much of an increase in my electric bill can I expect? There are a lot of variables to consider however, the average home is between $6 and $10 per month. The Broan ERV200TE uses under 20 watts at low speed and that equates to $2 a month in electricity usage. The Venmar EKO uses as little as 26 watts and uses less then $3 a month in electricity. Others use a little more, some up to $20 per month. The question is really this: Is your health worth it? ​ ​ What if it's the stuff in the outside air that bothers me most? Allergens from outdoors like pollen, especially in the spring time, can cause a lot of problems. One of the advantages of a ventilation system is you control the inbound air stream; this gives you the opportunity to filter (clean) said air stream. A variety of filters can be used such as Pleated, Carbon(Charcoal), Electrostatic and HEPA Filters. ​ Pleated Filter - UL Class 2 filter. Arrestance (measure of the ability of an air filtration device to remove synthetic dust from the air. The arrestance describes how well an air filter removes larger particles - such as dirt, lint, hair, and dust). is 90-92% and efficiency at 1 micron is 21% ​ Carbon Filter(Charcoal) - UL class 2 filter. Average arrestance is 80% according to ASHRAE. ​ Electrostatic Filter - The filter's electric field captures particles of 0.3 microns or more without producing ozone or ions. The efficiency at 1 micron is 90%. DC 12 volts & uses 1 watt. ​ High Efficiency Particulate Air (HEPA) Filter - Removes 99.97% of particles that are 0.3 microns (also called micrometer) or larger. ​ As a point of reference, the average human hair is ~50 microns in diameter; the longest chromosome in our DNA is ~10 microns long and a strand spider web is ~3 microns in width. ​ Is it a big job to install an air exchange system in an existing home? It all depends on the home. Most can be installed in 3 to 5 days ​ How long before I notice an effect on my Indoor Air Quality? Many customers notice that within only a few hours, the house feels fresher. Many of them have shared with us the various benefits they receive. ​ Is a whole house system going to be noisy, will I hear it? Due to these systems being designed for homes, there are ratings on the noise level that these systems generate and are called sones. These units are designed to produce little noise. Most systems when run on low speed, are very quiet. High speed will carry a higher level of noise due to increased fan movement and air speed and is typically is not a complaint issue in the home. In fact we have had very few complaints on noise levels. ​ Considering other things in the home that produce noise such as furnaces, heat pumps, refrigerators, air conditions most people think these systems produce a lot less noise than those. Unit location plays a hand in how much noise can be heard. ​ What exactly does home ventilation mean? As we move to the future we try to be as energy efficient as we can. With that, we close up our homes nice and tight to make sure no heat gets out; but is living in a balloon really very healthy? Energy-efficient homes -- both new and existing -- require mechanical ventilation to improve and then maintain indoor air quality. ​ How do I know if it's right for me? Is it expensive? The first thing you need to consider is how high a priority is the well being of you and your family? If there is something harming you and you can't see it, do you want to know? If you knew, would you want to fix it? Price varies per house by quite a bit. The best way to know the cost is to Request An Estimate . Generally speaking however, for a ventilation unit prices range from around $1,000 to about $3,000. The higher you go in price, the more energy-efficient the system is. ​ What process do you take to create an estimate for me? There are several questions we ask to help us determine the closest possible response. Please see our estimate page, currently on our .net website to Request an Estimate. ​ My electrician/plumber/contractor says he can do it for a lot less, why is that? If they're installing a system properly for a significantly lower cost there's probably something wrong. In the United States there is no certification and no requirements for a "correct" system. Kurt Johnson went to Canada where they have a certification program and received proper training for system design and installation through the HRAI SkillTech Academy, Certification #8630. ​ ​ What about specific rooms; or just ventilating my basement? Ventilating a basement is a good start as radon and mold are very common there. But due to a phenomenon known as 'stack effect' air wants to move up. Ventilation in the basement will reasonably reduce the effects of radon and mold, but it's still possible to find their way into the rest of your home. Regarding effectiveness of reducing radon levels, in a basement or elsewhere, the Maine Radon Director Robert Stillwell has stated that ventilation can reduce radon by up to half. ​ ​ What is Cross-Flow, Counter-Flow an Enthalpy Wheel? These are different design strategies each intended to extract the most heat and/or moisture from the outgoing airstream as possible. ​ Cross-Flow is the more commonly recognized in which the shape is a square turned at an angle, some call it a diamond, in which the air moves through in an X shape without mixing. ​ Counter-Flow ​ Enthalpy Wheel, also called a rotary heat exchanger or thermal wheel, is a cylinder turned on it's side inside of a cassette. Sensible efficiency around 85%. We usually encounter these in older units, and the cost to replace the wheel is roughly the same as a newer unit. ​ ​ Still have questions? Well speak up then!
