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.

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.

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.

Allergies, Clean Air, & You
You know the misery! The itchy eyes, the runny nose, sneezing, and coughing. Even if you stay inside most of the time there seems little relief. In fact sometimes the symptoms of allergies get worse. Why is that?
Well, it is reported that in the spring most allergy symptoms are caused by pollen or mold spores. In fact, up to 72 trillion allergens find their way into your home every day! Mold spores can irritate the respiratory system. Dander from pets can float in the air and be an irritant.
Then there are those pesky dust mites that lurk in bedding, upholstery and other soft material and generate irritating waste particles (poop) that become airborne. Of course DUST is the big culprit. Did you know that the average home generates about 40 pounds of dust per year in a 1500 square foot home. Yikes! If you live in the Treasure Valley of Idaho you know what I am talking about, don't you?
The other factor in allergies and clean air is, homes built today are more airtight then ever, trapping more allergens indoors. So now 70% of U.S. households are affected by allergies or asthma.
Solution? Improve your indoor air quality by installing a 'whole-house' electronic air cleaner such as,
TRANE CleanEffects. As published in BioMed Central Journal, Trane CleanEffects has been shown to remove up to 99.98 percent of particles and allergens from the filtered air. It traps particles as small as .1 microns! That is 100 times smaller than a human hair. If will even capture influenza virus. comfortguyjerry has one in his home and my wife loves it. Check our website for more information at www.greensheating.com.

Why Is A Matched System Important?
As we approach the summer months, we might start remembering how hot is was last summer, and we were remembering that our A/C didn't seem to be keeping up and keeping us cool. Maybe we remember how much noise our A/C was making and how rusted out and dirty our outdoor unit was. In either case, we should think about whether or not it is time to replace it.
If you replace a outdoor unit that is 15 years old, you will need to replace the indoor coil that fits above or below your furnace. The reason being is, that all new systems call for the new R-410A refrigerant that is environmentally friendly.
Here is what you may not know. If your replacing the A/C outdoor unit and the indoor evaporative coil, you SHOULD replace the furnace at the same time. I know, your saying there is nothing wrong with the furnace and we don't use it in the summer!
Air Conditioners, Heat Pumps, Furnaces and Air Handlers have energy efficiency ratings. The only way to achieve those ratings is by installing a matched system. There are SEER ratings. (Seasonal Energy Efficiency Ratio) There are HSPF ratings. (Heating Seasonal Performance Factor) There are EER ratings. (Energy Efficiency Ratings) and the like. These are standards of energy used in comparison with comfort and air delivered. Its all very technical I know. @comfortguyjerry is here to tell you, if you want to get an A/C with a SEER rating of 14, you will have to replace your furnace with a new one. Why? All of these ratings are tied together, meaning, the furnace has to be the right efficiency, the blower motor size delivering the correct CFM's has to be correct and add to that, your duct work has to be sized correctly. All these factors are required to get a 14 SEER unit.
Plus, when the installer comes out to install your new A/C, he going to have to pull your furnace out anyway to be able to install the new evaporative coil. Trust me, they are not just trying to sell you more product. Their goal is to help you get as close as you can to the efficiency that is stated on the equipment or in their literature. Don't make the mistake and assume that if you purchase a 14 SEER A/C that your are going to get 14 SEER. You will 'get up' to 14 depending on these other factors.

Is Your Home "Energy Ready" for summer?
Are you ready for hot weather? I don't mean running out a buying a swimming pool or swim wear. This means making sure your air conditioning system is ready to deliver cool air on hot days. Most of the things are easy DIY things that wont cost you and arm and a leg.
First: Change your filters in your heating/cooling system. You would think this would be a given but I have known folks that have not changed their filters in a couple of years! Change them at least twice a year and if you live in dusty or rural areas change them four times a year. Quick, easy, and cheap.
Next, change your thermostat over to 'cool' and test the system by turning the temperature down. If the air conditioner does not run, check your breakers. If it still does not come on, call your heating and cooling professional. If your system does turn on, make sure it putting out an adequate amount of cool air. Then, set your thermostat to your desired setting, or program it to perform at your comfort level. Setting it at 73 - 76 degrees in the summer will keep your cooling bills easier to swallow. But bottom line it is all about personal comfort.
On the subject of thermostats.Now would be a good time to install a programmable thermostat if you do not have one. You can save up to $100 a year using a new programmable set-back thermostat.
Now, if your air conditioner is 15 years old or older then you might think about replacing it with a higher efficiency model to save money and insure a trouble free summer for many years. The older our air conditioners get, they lose efficiency and even if you bought a high efficient model back in the day, it has lost a good measure of efficiency over time. The key is, DO IT NOW before it gets blazing hot in the summer because your heating and cooling professionals will be very busy when it gets hot. They will want to check your insulation and duct work in your hot attic, look at your windows, and other things to evaluate what system is going to be best for your home. Also air conditioners never go out in the winter do they? They always go out in July or August here in the Treasure Valley of Idaho.
Finally, don't be afraid to install ceiling fans in your home, especially if you have vaulted or high ceilings. I know they are not 'sheek' and decorators hate them and feel they don't go with your decor. But lets face it, we don't buy them because they are hip and fashion forward. We buy them because they move air, help conserve energy, and keep us more comfortable at higher room temperatures.

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.

Think 'Ductless' Heat Pump for Problem Homes
Here in the Treasure Valley of Idaho many home owners complain of rooms in their house that are too hot, too cold, too often. Think about it. If you have a a two story home I can almost guarantee that you complain about that bonus/family room upstairs being too hot in the summer. Many have bedrooms upstairs, or master bedroom at the far side of the house and always seems cold in the winter. Or maybe you have put on a room addition, sun room, or decided to have a shop or craft room put in the garage and now you need it to be comfortable. What is the solution? @comfortguyjerry would highly recommend a ductless heat pump. They are a perfect solution. What is ductless? It is just that. No built in duct work like your present furnace and A/C use. Instead you have an outdoor compressor about the size of a large suitcase. From there they run all the copper lines, electrical, etc up the wall in a covered channel and drill a three inch hole in your wall for the lines to through to the indoor wall unit, which is the evaporative coil/fan. The wall unit usually is mounted up close to the ceiling. The fan runs at whisper quiet, and special technology uses electronic sensors to locate hot and cold areas of the room and adjust the variable speed compressor to make sure of even comfort. No blast of cold air like from a widow air condition and not hot radiant heat that you can't get to close to or you will roast.
The benefits are numerous! No duct work, real comfort. Highly, highly efficient, and super quiet. Clean air to breath through a series of air filtration systems that give you clean air continuously. They provide both heat and cooling in one unit. There are several brands out there but @comfortguyjerry recommends Mitsubishi Ductless Heat Pumps for quality and durability.
Ductless units are being used in over 80% of homes in Japan, China and Europe already, and have been used for decades. For more information check these websites: www.mehvac.com or www.greensheating.com.
