Indoor Air Quality And You - Part 3

     Here in the Treasure Valley area of Boise, Idaho, we live in what is called the high desert. We have good share of dust and allegens from trees and desert grasses and weeds. So, let's talk about HEPA filters. HEPA is an acronym for 'High Efficiency Particulate Air'. A true HEPA is a type of filter that removes at least 99.97% of particulates such as dust, animal dander, smoke, mold and other allergens that are 0.3 microns or larger, from the air. Most residential heating and cooling systems are not able to accommodate such filters because of there physical dimensions and increase in airflow resistance. There are bypass HEPA air cleaning systems that are ducted off the heating and cooling system but only clean approximately  30 percent of the air traveling through the duct work.

      Portable air cleaners, are the type that treat the air in the immediate vicinity of the unit and are not intended for whole-house filtration. Here is why I discourage using them.
         1. They treat the air only in the room they are being used in.
         2. Separate units are required for each room.
         3. Often they are noisy and obtrusive in living areas.
         4. May not be as energy efficient due  to the need for multiple units.
         5. Require more frequent cleaning and maintenance. Filters need changed every 
             one to three months.
    

All of that being said, why not consider the best solution for your home and health? A WHOLE-HOME air cleaning system. I know that sounds expensive, but in reality, they are not. They can improve the efficiency of the central heating and cooling system by as much as 25% by trapping and removing harmful dust, dirt, dander and hair that would otherwise settle on your equipment.
       They are designed to last as long as your heating and cooling system, and filters require changing anywhere from 1 to 2 years, or some can be cleaned and used for up t 10 years before changing.

HVAC Cost Reality Check

       Probably the most common question I get in the heating and cooling business, is, how much does a air conditioner or furnace cost? Most folks are surprised at how expensive a new heating or cooling system can be. The reason for their surprise is most likely due to the fact that they have never had to purchase a new unit, or system in their life. People today are so mobile that every few years we move to a different city or home, and there is already a working HVAC system installed.
     I know that here in the Boise, Idaho area in the past 10 years we have had a phenomenal growth spurt in new housing, so there are many fairly new systems installed already. So, you have been in your home 15-20 years old, it is time to replace your HVAC system. You call around and arrange to have someone call on you, and evaluate your needs and give you a proposal for new equipment. That is when the shock comes! The cost! Most folks have no idea. Well, allow me to give you a reality check and bring you up to date.

     The most popular size of Air Conditioner here in the Treasure Valley, is a 2.5 ton unit. That is what most homes that are 1500-1700 square feet will need. That air conditioner will cost, installed, on average $2800.00 to $7000.00. The huge spread is determined by what EFFICIENCY you want to purchase. Efficiency ranges from a rating of 13-20 SEER, for most central air systems. (kind of like miles per gallon on a car). Back in the day you could only choose from one or two efficiency models from any dealer because that is all they had.
      On the furnace side, most people who have a 20 year old home most likely have a 80% efficiency furnace installed and today you can get a much more efficient 95% furnace installed in that same house size mentioned earlier, for $3000.00 to 6500.00. Now, I will mention that right now you can still replace your old furnace with a 80% efficient model just like you have, and they are less money, but it really is not a good idea. If your going to spend the money, why not upgrade to a more efficient model.

     Now, do the math. a complete system will cost between $6300.00 and $13,500.00. Now, here's what I want you to think about: Most people will spend $20,000-30,000. for a brand new car. They spend maybe an hour or two a day in their car traveling to work, shopping, etc. Most folks keep their automobile on average about 7-8 years.  When you purchase a new HVAC system, it is half the cost of a new car and you spend about 15 hours a day in you home, plus you won't be replacing it for 15 to 20 years. When you just look at the money side of the issue, which is the better investment, and which is going to give you the greatest return on your investment?

Breathe Easy With Clean Air At Home

     More and more we are hearing about the importance of clean air in our homes. Part of the work of the Environmental Protection Agency (EPA) is to promote and insure clean air in our homes, cities, and states. It is a well known fact that often there are more pollutants IN our homes, than those outside our homes. It is also well known that millions of people suffer daily with asthma, pulmonary lung disease, allergies, hay fever, and reactions to mold, mildew and dust. What is a person to do to have clean air in their homes?

     We can't live in a bubble, so the best thing we can do is to first, eliminate as many of the products from our homes that cause irritation to our lungs. Things like perfumes, chemical cleaning compounds, pesticides, and the like. Even carpet can be a host home for many airborne allergens and dust. Personally, I like carpet. Living in the Boise, Treasure Valley of Idaho, carpet feels really nice on a cold winter morning. So for me, getting rid of my carpet is not going to work. In the summer we live outdoors as much as we do indoors so the doors are being opened and closed and that allows more pollutants into our home.
     What I can suggest, and what I am using, is a 'whole home' electronic air cleaner.
These units install right in the return air duct of your central heating and cooling system. There are some units on the market like, Trane CleanEffects, that will purify the air down to .01 microns. This will scrub the air of 99.98% of mold, mildew, influenza, allergens and the like.

     A good air purifier should be at least a three stage system, including a pre-filter that will pick up most dust, lint, pet hair, & etc. The second stage is usually the electronic part in which the atoms are changed to attract pollen and other allergens. The third stage generally consists of specially manufactured filter material that filter out the microscopic bacteria and dangerous influenza. At the same time as these filters are working, your system delivers clean, purified air to your home. A quality system like Trane CleanEffects does not require purchasing new filters for up to ten years. The filters can be vacuumed, washed, and replaced.
     Some folks like to use small portable air cleaners but, frankly, these do not perform as well as a whole house unit in delivering clean air. Plus, they are really only good for a single room or area. Others use what are called "HEPA" filters and 4" pleated filters in their furnace, and these are good, but again. they do not capture 99.98% of pollutants and they do not capture influenza virus. So, to breathe easy at home. To save money by not going to the doctor so much. To ease up on your purchase of over-the-counter allergy medication and perscription medication. Invest that saved money in a whole-home air cleaning system. For more information, check my other blogs at hvaccomfortguyjerry@blogspot.com or go to our website at www.greensheating.com.

What Size HVAC System Do I Need?

@comfortguyjerry had an interesting sales call this week here in the Boise, Idaho valley, and I thought it was important enough to blog about it. It has to do with the size, or tonnage of an air conditioning unit you need for your home.
     This gentleman, called our service center and wanted a quote on a 3 ton air conditioner. Immediately our receptionist put him on the phone with me and instead of just ball parking a price, not knowing the whole picture, I set up an appointment to go to his home.
     At his home I found out that several years ago his brother-in-law provided him a "refurbished" 3 ton A/C unit when his original unit went out. I ask him what the square footage of his house was. He told me 1300 square feet. Needless to say, a 3 ton unit was too big. He only needed a 2 ton unit, based on square footage only. I told him 3 ton was too big, due to the fact that the DUCT WORK in his house, when it was built, was sized for a 2 ton unit. Guess what? His current three ton unit was freezing up in the hot summer months and the house wouldn't stay cool. The rings in the compressor have warn out as well. The reason? Over sized A/C unit!  But he kept insisting he "wanted it cool!" this summer. He wanted a 3 ton unit!
     Why am I telling you all of this?  I hate to say it because I am a man, but men have this idea that more is better. You know, if one aspirin is good, then taking four aspirin must be better. "Bigger is better". "Heavier is better". Its a man thing.
      Here's the point. When you have a heating and cooling system, remember it is a 'system', not a air conditioner or a furnace. It is a complete system. That includes the outdoor unit, the furnace, the evaporator coil, the duct work, the return air ducts, and even the thermostat is important. They all have to work in concert with one another to achieve the desired results. For more information go to our website at www.greensheating.com.

Clean Air and Heart Health

      Seventy percent of U.S. households are affected by allergies or asthma. These folks are more susceptible to harmful particles and allergens from the air INSIDE their homes. In fact, up to 72 trillion allergens find their way into your home every day. Add to that, if these family members have heart issues, the problems caused by unclean air are compounded.

     The EPA states, that exposure to fine particles impairs breathing, and increases the risk of stroke, heart attack and other serious health problems. Particles like dust, smoke and bacteria are often .3 microns in size or less. At that size allergens can get deep into your lungs because they aren't filtered well by your nose and throat.
    Many experts tell us that there is often more allergens and contaminants inside our homes then there are outside. Why is that? Well, today's homes are built better, tighter, and insulated better then in decades past. Now, this is a good thing, but it is also a bad thing, in the sense it traps particles, off gases, pet dander and the like inside our homes. We rely on a little one inch pleated filter in our furnace, or in some cases a four inch filter to clean our air. These filters are okay if you don't have health issues related to unclean air. What is the answer for those of us allergy sufferer's?

     According to the 2007 Consumer Digest report, Trane 'CleanEffects" whole home air cleaner is the highest rated professionally installed electrostatic precipatator on the market. "CleanEffects" has been shown to capture 99.98% of all airborne allergens, down to .1 microns in size. It will even capture influenza virus like the swine flu.

So, the irritants like hair, pollen, mold spores, skin flakes, bacteria, dust, tobacco and cooking smoke are scrubbed from the air.
     As published in the BioMed Central Journal, an independent publishing house committed to providing access to peer-reviewed biomedical research, and as accepted and presented at the Indoor Air conference, Trane "CleanEffects" has been shown to reduce triggers for allergies and asthma, and can be an important part of your overall allergy and asthma management plan."

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.

Air Conditioner Preventive Maintenance - Rx for Longevity

     This morning I had a doctors appointment to see why I have been having shoulder pain, and It got me thinking about the importance of having health problems checked out by a medical professional. A doctor can evaluate the problem, do a diagnosis, and offer different types of treatment to restore our health. Sometimes it's a simple fix, other times it may involve extensive treatment or even surgery.

      Now, the question is; what does this have to do with my air conditioner, or my HVAC system? Well, think about it. We spend a pretty good chunk of money to invest in a heating and cooling system to keep us comfortable year round. We also hope that we can get some longevity out of that system, so we can feel we have made a 'healthy' investment in our home.
     We usually go once a year to get a physical for our own health and longevity, so, why not see the same importance for the longevity, and health of our air conditioner. Here in the Boise, Idaho area we are going to see temperatures reach 106 degrees in just a few days and that is going to make our air conditioners work overtime and put real strain on its 'heart', the compressor.
   During the 'house call', your HVAC 'doctor will do a physical inspection, run some 'tests' as to the health of the electronics, the 'brain', take the 'blood' pressure of the freon, running through the copper 'arteries' of the system. The 'doctor' will also clean out the system. If you are having problems, he will 'diagnose' the problem and write out a 'Rx' to bring your air conditioner back into a state of health. If something has broken or burned out, he most likely will perform 'surgery' to correct the defect so it can 'live' healthy for many years to come.

  This is why we should have a yearly 'physical' done on our A/C to make sure our system is healthy and operating at maximum efficiency. A yearly check up is really the 'Rx 'for making our A/C operate trouble free for many years.

Save Energy with Proper Insulation

     Almost half of your electric bill goes to heat and cool your home. If you want to save money on your heating and cooling bill, then start by looking at your home insulation.

     Insulation is important to minimize, or eliminate the heat exchange/loss inside your house. Good insulation keeps the interior warm during the winter, and cold during the hot summer. A well insulated house allows your heating and cooling systems to effectively work as needed. The proper amount of insulation can save as much as 10% on your monthly electric bill.
   If your house has air leaks, or if it has insufficient insulation, air will pass through
 and heat exchange will be greater in areas where insulation is inadequate. This will result in heat loss and make your HVAC system run more, and use more energy. Even if your cooling in the summer, and their are leaks or poor insulation, the cool comfortable air will pass right out of the house. Many mobile homes and manufactured homes are perfect examples of this. Because of the style of construction, they have inadequate insulation in the walls and ceilings, so they fail to trap and keep the warm or cool air in the house.

     Make sure you consider factors such as building design, budget, local codes and climate when selecting the R-values of insulation material. Consider parts of your house such as the attic, floors, kitchen bathroom, windows, walls, doors, etc. If you are building a new home, check on some construction materials that provide both structural support and good insulation.
     Some utility companies offer incentives or rebates, to upgrade your insulation.  For more information, contact your local utility company to see what they offer.

Is A Heat Pump In Your Future?

     When you think of cooling your home, you probably think, "air conditioner", evaporating cooler (swamp cooler), or window fan. As it turns out, a heat pump can be a preferred way of cooling your home. Wait! "Heat to cool your home?? Well, that is a bit of misnomer. But a heat pump can both heat, and cool your home.

     In some parts of the country where the winter temperatures seldom get below 35 degrees, a heat pump is a great advantage because you won't need a separate back of heat source like a furnace or air handler. Where we live in the Boise, Idaho area, we still get some pretty cold mornings and we have to have a back up heat source, due to the fact that heat pumps began to lose efficiency at about 30 degrees. Once the outside temperature gets above 30 the furnace will seamlessly turn off and switch over to heat pump use.
     Let me explain how they work. I am going to focus on 'air source' heat pumps because, they are most commonly used in residential air conditioning, and they look exactly like an air conditioner. They use the ambient air temperature to heat. The operative word in heat pump; is the word pump. What makes them energy efficient is, that instead of 'making' heat, or 'making' cold air, They are in essence pumping, or transferring cold air out of your home in the winter, and replacing it with warm air. Moving air is more cost effective then manufacturing air. In the summer time, it reverses the process, moving hot air out of your home, and replacing it with cold air. It works much on the same principle as your refrigerator. Not to get too 'techy' on you, but, remember back when you were in school and they taught you in science that 'cold' is merely the absence of heat. and 'heat' is merely the absence of cold. That is basically the same principle heat pumps work on.
     So, why hasn't everyone switched to heat pumps. The reason is, that, in much of the united states we still get some very cold weather and a heat pump is not as efficient as a furnace in those areas. In most cases though, it is less expensive to run an electric heat pump than to run a gas furnace. It is staggering less expensive then propane or resistance heat! (baseboard, ceiling heat, or electric furnace) Overall they are a smart choice for many homeowners, and most heat pumps are energy star rated. They also don't cost much more than an A/C unit. @comfortguyjerry has one at his home and we love it. My  natural gas usage the first winter we had it was cut in half! My electric bill went up slightly. I installed a 16 SEER heat pump and a 95% efficient furnace, and I know I am saving 25-30% on my overall heating and cooling bill. For more information on heat pumps go to our website at www.greensheating.com. Maybe a heat pump IS in your future.

The Most Important Day In The Life of Your HVAC System

     The single most important day in the life of your furnace or air conditioner, is the DAY IT'S INSTALLED. That may seem to you like a strange statement. My blog today is designed to explain why that is true. Simply stated, you can purchase the most expensive, highest efficiency, top rated brand, and, if it is not installed correctly, then you will not get the service, or efficiency that you shelled out your hard earned money for.
     There are several factors that are involved in having a properly installed HVAC system. First and foremost is the importance of purchasing a matched system. That means, the furnace, condensing coil, and air conditioner (or heat pump) should be the same brand. You will also find that there are a number of condensing coils to chose from to match up with the air conditioner, and your HVAC company should and can do a correct match in order to give you the highest efficiency possible.
     The next factor is duct work size. To deliver the correct amount of air to your home the duct work has to be sized properly in proportion to the cfm's (cubic feet per minute) coming from the blower motor in the furnace. To give you an example: Let's say your duct work is sized to handle air movement from a 3 ton blower motor but your blower motor is a 4 or 5 ton blower. Obviously you are going to get back pressure because your duct work cannot deliver that much air efficiently. The opposite of that is true as well. If you have duct work designed to deliver air from a 4 ton blower and your furnace only has a 2 ton blower, then it is going to have a hard time warming or cooling your home. In either case, it will cause increased wear and tear, and shorten the life of your equipment.
     The last factor I will mention is the importance of the correct refrigerant charge. That means too much Freon, or too little Freon in your A/C will also be a problem for your system.
     The North Carolina Alternative Energy Corporation, which is a non-profit organization, examined air conditioning manufactures' efficiencies, versus the actual efficiencies that resulted after installation. They found that 90% of the units tested exhibited some sort of energy-wasting, comfort-robbing problem! What were they? 54% had a incorrect refrigerant charge. 70% had incorrect air flow, 93% had duct leakage, 47% of the units were over sized for the home. So, the hope of @comfortguyjerry is to help you see the importance of hiring a quality company, with the a long standing reputation for doing the job right the first time. Remember, The most important day in the life of your HVAC system, is the day it is installed. Check our website at www.greensheating.com.

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.
