Indoor Air Quality and You

     Air is absolutely essential for life. The problem is that the purity of the air is not assured. Outdoor air pollution is pretty obvious, but indoor pollution is not always so readily noticed. The impurities found in homes can build to levels that have a direct effect on our health and quality of life. One report from 2007,  based on independent testing of the air in 10,000 American homes across the country, that 96% had a least one type of indoor air quality or IAQ.
     What does this mean to you? When allergy problems send people to the doctor, invariably the patient asks about about air filtration. Patients want to know what they can do to reduce the pollutants in their homes. Many ask about air cleaners and doctors are telling them that air filtration should be part of their comprehensive health strategy.

     To help you understand about air filtration for your home, there are three approaches to improve air quality.  They involve, Source elimination, Ventilation, and Air Cleaning.
     Source Elimination is just as implied. Doing things in your home to reduce or remove the source of pollutants. Examples would be, not smoking indoors and removing animals, plants and solvents from your home.
     Ventilation is critical, especially in newer homes. New construction methods utilize energy efficient window and doors, extra caulking and weather stripping, along with more insulation. The problem created is, that tighter construction means decreased movement of outside air through the home. The lack of ventilation leads to a build up of stale and dirty air. According to the EPA, the lack of air movement throughout homes can lead to concentrations of pollutants up to a hundred times greater inside a home than outside.

     Air Cleaning by the use of filters and or whole house filtration systems are a vital part of the strategy in improving your overall health. These cleaners remove the particulate matter that remains AFTER source elimination, and ventilation have failed. Some whole house electronic air cleaners can capture particles as small as .01 microns. That is pollutants like influenza, and other bacteria. Because they are part of your heating and cooling system they clean the air in your entire home.
     As time goes on I will share more things about indoor air quality. You can read more of my blogs at www.hvaccomfortguyjerry.blogspot.com, or go to our website at www.greensheating.com.

Summer Energy Tips for Home and Business

Summer is here in the Treasure Valley of Idaho, and so is the heat. It will get to 100 degrees today and high 90's the rest of the week. When the temperatures rise, cooling can be the largest part of summer electric bills. The Idaho Power Company has provided these tips to help you be energy efficient.

FOR YOUR HOME
Adjust your thermostat up to 78 degrees, or use natural ventilation to cool during the night.
When practical, use your microwave or barbecue grill instead of your stove top or oven.
Use a clothesline or a clothes drying rack when possible. (Who knew)
Turn off fans when you leave the room. Fans cool people, not rooms.

FOR YOUR BUSINESS
Make sure your thermostat program direct digital control system is programmed properly.
Evaluate and replace outdated lighting.
Install occupancy sensors in all enclosed offices, small spaces and meeting rooms.

FOR BOTH HOME AND BUSINESS

Close your blinds on south-and west-facing windows during warm summer days to keep out un-wanted heat and reduce air conditioning use.
Tune up your HVAC system. Get you system serviced regularly and  replace air filters.

What Matters Most In the Summer

It's good for us to stop for a minute and think seriously about our planet, and our use of it's resources. Slowly, we here in the western world are becoming more and more aware of our energy consumption, the waste we dispose of or recycle, and how we care for our small piece of the planet. Sometimes we think it is just too overwhelming for us to think about protecting the resources we have come to love and appreciate. So my suggestion is to start small, start in our own homes. If each of us would start there, our small differences would eventually make huge differences for our water, our atmosphere, our food, not to mention our health.
     Here in the Boise, Idaho area of the Treasure Valley, Idaho Power Company has outlined some things we can do to in our small corner of the world. Did you know that heating, air conditioning and water heating account for 46.7% of our energy consumption in the summer months? Our home appliances account for 13.6% of our energy consumption. So if we want to rein our summer electric bills, then we need to concentrate on the biggest pieces of the pie first.
     Questions we can ask ourselves:
        Are you using fans to stay cool and cooking outdoors when possible?
        Does your A/C filter need cleaning or replaced?
        Are the coils on your A/C unit dirty or clogged up?
        Can you adjust your Thermostat up or use natural ventilation to cool at night?
        Are you doing full loads of laundry and dishes, line drying your clothes if  
        possible.       
        Any incandescent that could be changed to compact fluorescent lights?
        Could you upgrade appliances or HVAC units to 'energy star' rated products?
        Do you have an extra refrigerator that could be recycled?
        Is your water heater temperature set at 120 degrees farienheit?
Most of the things I have listed from Idaho Power are fairly inexpensive to do or cost us nothing. It's just something we need to think about more often. You would think the power company would be interested in selling you MORE energy but in reality there is only so much energy to go around and so they are very much interested in our saving energy and I am sure all power companies are as well. I hope this blog causes all of us to think a bit more about our planet and to let you know that @comfortguyjerry is interested in more than just 'comfort'.

"Mini-Splits" Are Not A Small Banana Split!

     Now that I have your attention, I want to talk about electric ductless heat pumps and cooling systems. These are often called 'mini-splits' because there are actually two parts to the system. There is an outdoor unit or compressor, and a indoor unit that mounts on the wall that is the evaporator/fan blower. There is no duct work involved. The ductless heat pump can both, heat and cool your space. A cooling only option is available in ductless units also.

     In countries like Japan and China, upwards of 90% of homes use this kind of system, and have for decades. Central America uses them extensively in private homes and resorts. The U.S. Military uses them to cool the barracks and mess halls in Iraq and Afghanistan. It is just here in north America that we are slow to catch on to the idea.
     The most common question @comfortguyjerry gets regarding ductless heating and cooling is: "Will that one unit take care of my whole house?" The answer is, no. They are designed to provide comfort for a single space. That single space can be a 'great room', a bonus room or upstairs family room, room addition to a house, or a shop. It is also very effective for mobile or manufactured homes. I think you get the idea. To do an entire home would require additional outdoor units, and multiple indoor 'heads', depending on your needs and size of your home.
     You say, 'that sounds expnsive', and it can be, depending on what your needs are. The economy comes in during the monthly operation. They are so, so much more efficient, than traditional heating and cooling systems, and super high efficient central heating and cooling is expensive also. Ductless units are super quiet as well, being rated at just below a human whisper for many brands.

     Let me share with you what I mean by cost efficiency. In the Norhtwestern states of Idaho, Washington, and Oregon. To heat with a wood stove will cost $24.31 to produce a million BTU. A propane furnace will cost $57.45, a natural gas high efficiency furnace (95% efficient) will cost $14.73. A ductless heat pump, aka, mini-split, costs only $8.20 to produce that same million BTU, and no pollution to the atmosphere. You do the math. They will pay for themselves in no time.
     Think of it this way. Why turn on every light in the house when you need to use the bathroom? That's what you do every time your furnace or A/C come on. With ductless you only heat or cool the rooms that you need to, or use. I am also convinced that Mitsubishi makes one of the best ductless units on the market today. So the next time you hear the word "mini-split", don't start to salivate for ice cream and banana's.

Reducing Electricity Use in Your Home

     In most parts of the country we see a slow but steady rise in our utility bills. To help buffer the rising costs of electricity in our homes, many folks inquire of their local utility companies what they can do to save money. So, what are the 'best' energy improvements you can make? Well, first look at your insulation levels in your attic, and in your floor crawl space. Make sure your attic insulation is up to code, or what your power company recommends for your area. Some states offer rebates, or tax credits for adding more insulation to the attic. Insulated floors or crawl spaces are important to keep cold air from getting into your house through the floor. (An extra tip, is to close your foundation vents in the winter to keep cold air out, and to open them in the summer to allow ventilation. Easy to do if you just remember to open them the first time you mow your yard in the spring)
     The next thing you can do, is to install compact fluorescent light bulbs (CFLs) in your home's most-used fixtures. Also, if you have an old, inefficient refrigerator in your garage, think about upgrading to a 'energy star' rated fridge. Some utility companies will even 'pay' you and pick it up and get rid of old ones. They call it 'Cash for Clunkers' programs, etc.
     What about good DIY projects for spring and summer that can save on your utilities? I feel like I have said this a million times but, CHANGE THE FILTERS in your furnace and air conditioning systems. Clean leaves and debris away from the outside A/C unit. Spring is a good time get up in your attic and check to see that your duct work is all connected and sealed. Go into your crawl space with a flashlight and make sure duct work is connected and not leaking. If you feel that this is a bit beyond your DIY abilities, then call your local heating and cooling professionals, and have them come out and do it for you. It may cost you as little as a hundred dollars or so to have that checked.
     Okay. You say you just don't have any money to spend for improvements. What can you do?
Electricity use is determined by two variables - watts and time. Efficient appliances save you money because they either take less time to do a job, or use fewer watts. So use this principle and apply it to each electricity consuming activity in your home. Turning things off when not in use, like lights. Enabling power saving features on you computer and monitor reduces watts used. I looked around my house one morning while it was still fairly dark outside and I was amazed how many things were using watts! Every little red, blue or green light on our clock radio, cable television boxes, wall chargers for our phones, tablets, & laptops The clock lights on our stove and microwave, our alarm clocks, our irons that are still plugged in and flashing. There may be lights on our digital washer and dryer that are on all the time. Now, I'm not saying run around and turn them all off, or unplug them, but, could we do a better job of turning off or unplugging the non-essential cords and apparatuses we have.
     Raising the thermostat a couple of degrees can also reduce watts being used, by reducing run times on your air conditioner, and saving you money. I know these are little things, but little things begin to add up, and over the course of a year save you money.

Take Good Care of Your Air Conditioner

If you have central air conditioning, there are some things you can do to take care of your outside unit, so when it is blazing hot this summer it will take good care of you. Let me tell you, @comfortguyjerry has seen some outdoor A/C units so filthy, and coils so clogged up it was a wonder the motor and compressor had'nt  burned out. So, how can you take good care of your air conditioner? A couple of things I do in the early spring before we start to use it is this. Hook up a garden hose and give the A/C unit a good 'bath'. Flush out the coils both from inside out, and outside in. Over the winter there is a lot of dust, leaves and debris that get trapped in the fins of the coil and a good flushing will dislodge all of that. Let it dry for a couple of days before turning it on. The other thing I do is after I have mowed the yard, I get out my leaf blower to blow the grass off the sidewalk, patio and driveway. I always go by the A/C unit and use the blower on it as well. That keeps the dust from building up. Your unit will run better and more efficiently. Of course the best advice I could give you is to call your heating and cooling professional and have them do a 'tune up' on your unit. Not only will they clean the coil but they will go through the whole unit and check freon levels, pressures reads, electronics, etc to make sure your system is running at max efficiency. Sometimes they can see where there are potential problems that may need to be addressed. Remember: Care for your A/C now, and it will care for you all summer. At Greens Heating and Air we go through a 14 point inspection when we do a tune up. Check our website for more details at www.greensheating.com.

Going Green with HVAC

Usually when we start talking about going green we think in terms of buying a hybrid car, using recycled paper products, recycling, and the like. Literally there are numerous things we can do to be a little kinder to our planet. After all, we have no other place to live. @comfortguyjerry would like to explain the role of a new heating and cooling system, and how it can impact your life in terms of comfort, but also in terms of taking care of our environment. For instance, you might consider installing a Heat Pump instead of an air conditioner before summer. Their are several advantages to heat pumps, and they work well in most parts of the U.S.A. What is the difference between a air conditioner and a heat pump? First, a heat pump will heat your home, AND cool your home. Second, it will usually heat your home at a lower cost than gas, propane, or electric resistance heat like baseboard or ceiling heat. How can that be? Well, a heat pump uses either ambient air, water, or the ground to move heat and cold to and from the home. It requires less energy to MOVE air then it does to PRODUCE air. Furnaces manufacture or produce warm air from the get go. Heat Pumps, essentially pump or move cold air out of your home and replace it with warm air, using less energy. Now in most cases you will still need a back up heat source in the form of a furnace or air handler. Here is why. First you have to have a blower to deliver the air to the home, and your air to air heat pump will begin to lose efficiency at about 30 degrees above zero. So the thermostat is set so when the outside temperature drops below 30 degrees above zero, it will automatically switch over to your back up heat source, ie, gas, propane, or electric furnace. When you are using a gas furnace and a electric heat pump this is called a hybrid system. Its kind of like a car that runs on electricity and gas. So your heat pump will heat your home 90% of the time and the more expensive back up heat source will only run 10% of the time, therefore saving you money. What does that mean as far as going green? Well, your gas or propane furnace is putting less noxious gases in the atmosphere like carbon monoxide, etc.
     Of course in the summer when you're wanting cooling, the heat pump works just like an air conditioner, and as far as efficiency is concerned they are both rated at anywhere from 13 - 20 on the efficiency scale called a SEER rating. The higher the number, the more miles to the gallon, as it were. So if you want to save on electricity use as well, then you are smart to select the highest SEER rated heat pump you can afford.
