Heat Pump Air Duct Requirements

Monday, April 23rd, 2012

Between the concerns about climate change and the rising costs of energy production and consumption, there is a lot of experimentation with new heat pump replacements in Beavercreek.  Standard choices are being re-evaluated and new designs are changing the requirements for various parts.

In homes and other buildings where systems were designed and installed according to the cheaper energy parameters prevalent in the day, it may be time to consider drastic changes to increase the efficiency and decrease impact on the carbon footprint.  Room for improvement can be found in many corners.

Heat Pump Technology

Among the systems getting a fresh look are heat pumps, a device that transfers thermal energy from one location to another, usually in the direction of from a colder temperature to higher and generally the opposite of the natural flow.  While compressor-driven air conditioners and freezers are technically heat pumps, “heat pump is the term that usually implies one of the less-common devices in the class that are not dedicated to refrigeration-only.

Heat pump installations that maintain a thermally conditioned-space can be used to provide either heating or cooling, depending upon whether the environment is cooler or warmer than the conditioned-space.  Typically pumps utilize some thermal energy from the environment itself, such as the natural heat beneath the Earth’s surface.

By simply transferring the energy rather than producing it, heat pumps are being more seriously considered as attractive alternatives to provide an efficient and clean system for conditioning public and living spaces.

Change of Use

In considering a change from an existing system to a heat pump, there are many details to compare to see if it makes any sense at all.  The overall local climate (cool or hot) in general, and the availability of geothermal heat, in particular,  are two major factors.

Since a heat pump typically moves conditioned air through ductwork, the advantages of the change are much more realistic with a system of pre-existing ducts such as a forced air furnace or central air-conditioning unit.  While a heat pump often requires a larger volume of ducts, the old network of metal tunnels was often over-sized for inefficient furnaces and should do fine in a conversion to a heat pump.

The Right Data

Since the required formulas are dependent upon variables such as size, distance, volume and oomph, the design is strategic and makes all the difference.  Call Clean Air Act to speak with a trained and experienced professional.

Do the homework to get the best recommendation for your home.

Heat Pump Refrigeration Problems

Wednesday, March 7th, 2012

Heat pumps in Damascus are very complicated pieces of equipment that use a number of moving parts to compress and circulate refrigerant, and extract heat from one environment and place it in another. So, if your heat pump has refrigeration problems, it will almost certainly cause problems for the heating or cooling of your home.

Common Refrigeration Problems

There are a number of potential problems your heat pump might face, especially as it begins to age and components become worn. Some common issues include:

  • Compressor Issues – The compressor is a component in your heat pump that compresses the refrigerant gas into a liquid. This liquid is what circulates through the device and extracts heat from the outside air (or inside your home when in cooling mode). If the heat pump doesn’t turn on properly, isn’t producing enough heat or is using a large amount of electricity suddenly, it may be a compressor problem.
  • Refrigerant Leaks – Your heat pump doesn’t consume any refrigerant during operation. So, if it starts to leak refrigerant, there is likely another problem your heat pump needs to be repaired immediately (for health and environmental reasons). Common signs of a leak include suddenly higher electrical bills, inefficient heating and possibly even a faint odor near the device.
  • Freezing Up – If your heat pump freezes, you should check for any blocked air vents or registers, check the condensate line and check your filter for blockage. Most often, a freezing problem is directly related to something being clogged and is a relatively easy fix. The only way to know for sure is to call a professional to investigate, however.

A heat pump is a very complex piece of machinery with a number of moving parts that can all cause issues if not properly maintained. If your heat pump stops heating or cooling effectively and it is not a simple fix such as a filter or belt, you should call Clean Air Act to inspect for more significant problems such as the compressor or refrigerant.

Different Types of Furnace Maintenance

Friday, January 20th, 2012

There are different types of maintenance tasks associated with keeping your automobile in tip top shape. Did you also know there are tasks that can be performed at various intervals to keep your Happy Valley home’s furnace in peak running condition?

For example, the most frequent maintenance task is checking the filters in your air handling unit. These are often called furnace filters but in reality, they serve the same function to filter air to and from your air conditioner, too. It might be easiest to just call them air filters. The frequency of replacing or cleaning air filters usually depends on the type of indoor environment you live in – like humidity levels, number of household pets or occupants, etc. In general, filter maintenance should occur every one to three months.

A less frequent maintenance task is cleaning the moving parts of the internal mechanism. You may only need to have your furnace cleaned every six months to a year, depending on its use. In some cases you can perform the cleaning yourself or it is included in an annual cleaning as part of a service agreement with a qualified heating and cooling contractor. A furnace can typically run at peak efficiency when it is cleaned on an annual basis.

You can also make it a regular habit of checking the motor bearings and fan belt, too. You can lubricate the bearings and tighten or replace the fan belt on a same schedule as cleaning the moving parts.

Other maintenance tasks related to your furnace, which may require longer interval times include ventilation system cleaning, or more commonly known as duct cleaning. Some homes don’t require this type of maintenance more than every five to ten years – perhaps longer. Unless there are unusually high levels of dust, allergens, or contaminants in the air, most ventilation systems can remain clean for several years.

Of course, you can turn all of your maintenance tasks over to a Happy Valley heating and cooling contractor – and have the most peace of mind.

What to Expect in a Low, Medium or High Efficiency Furnace

Friday, December 9th, 2011

When buying a new furnace in Eagle Creek, you have many options. You can purchase a low end model to save money up front and you’ll still get exceptional fuel efficiency, but as you go up the scale, more innovative, money saving features become available. Here is a brief look at what you can expect based on which type of furnace you purchase.

Low Efficiency Furnace

This is a bit of a misnomer as even entry level furnaces have efficiency ratings of at least 80%. For comparison, if you’re still using an old gravity furnace, your efficiency rating could be lower than 50%. Modern furnaces are built to conserve, and while you won’t receive all of the bells and whistles that tend to accompany high efficiency models, you will get a durable, affordable furnace that will last for 10-20 years.

Medium Efficiency Furnaces

Furnaces in the mid-efficiency range have AFUE ratings of between 85% and 92% and are therefore significantly better than those in the entry level range. They also have some of the higher end features available in high efficiency models like programmability and the option for zone control. Because they are still mid-range, they are affordable without skimping too much on features too – a must for any homeowner wanting to save money on both ends.

High Efficiency Furnaces

The highest efficiency furnaces on the market are very different from those you would have purchased even just 10 years ago. Top end furnaces can carry AFUE ratings of up to 95% with a boat load of added features to conserve energy. These features include two stage gas valves so you can maintain a low BTU heating system for most of the year but crank up the heat when the temperature outside drops too low. They are also programmable, which allows you to easily change the temperature settings, fan speed and more from anywhere in the house.

And while they cost more to install, high efficiency furnaces use less energy over their lifespan, last longer and are more environmentally friendly than any other furnaces on the market today.

What Is a Downflow vs. an Upflow Furnace?

Wednesday, October 12th, 2011

When you go looking to buy a furnace in Clackamas, you may well be surprised by how many different elements go into making a good purchasing decision. There are simply so many different kinds of furnaces available now and they each are more appropriate for certain situations. That means that finding the one that’s right for you is less about finding the one best unit than it is about finding the one that is the best match for your particular circumstances.

This applies to the type of fuel the furnace uses, its energy efficiency, and whether it’s an upflow furnace or a downflow furnace. Energy efficiency and fuel types are probably things that you’re more or less familiar with. But what are we talking about when we classify a furnace as an upflow or downflow model?

Well, it’s pretty much what it sounds like. These terms refer to the direction the air flows as it is taken in and heated by the furnace. So in an upflow furnace, the cool air is taken in at the bottom, warmed, and then expelled at the top. A downflow furnace, on the other hand, takes in cool air at the top and expels heated air at the bottom.

While this is all very exciting, it may still not be obvious what impact this will have on your decision about what type of furnace to buy. The main thing you’ll have to think about when you’re deciding between an upflow and a downflow furnace is where the furnace will be placed in your house.

An upflow furnace is generally installed in the basement so that the heated air is directed towards the parts of the house you want cooled and so that the furnace can be appropriately vented outside of the house. On the other hand, a downflow furnace would be installed in your attic for the same reasons.

So where you want to have the furnace installed is probably the biggest thing to take into account as you’re comparing these two types of equipment. Of course, whether you pick an upflow or a downflow furnace, you’ll still have to select the appropriate AFUE, size and fuel source to best meet your needs. But making the choice between upflow and downflow can at least make it easier to narrow down your options.

4 Ways to Improve IAQ and Reduce Air Pollution

Friday, September 23rd, 2011

Your Gresham home could be  a haven for pollutants that can cause irritation to the upper respiratory system of anyone who comes inside. These allergens and pollutants are easy to remove however by taking some simple steps such as the four listed below:

  1. HEPA Filtration – Step one is to use HEPA filtration to remove as much of what is on the floor as possible through vacuuming. HEPA vacuum cleaners can remove years of cleaners, solvents, dander, mineral build ups and other toxins that tend to accumulate in spaces that normal vacuums cannot reach. It may be a bit of an investment, but a high powered vacuum cleaner can have a tremendously positive impact on your lifestyle and reduce pollutants.
  2. Stop Outside Stuff from Coming In – Some of the worst pollutants your home will face are from outside. So, make sure you have doormats at every door and that your family and friends remove their shoes before coming inside. You can have a second mat inside as a friendly reminder that cleaning the shoes is not an option but a strict necessity.
  3. Humidity Helps – Humidity levels between 30% and 50% reduce the presence of dust mites, molds, bacteria and many other indoor pollutants. Air conditioning in the summer is helpful to reduce humidity, though a dehumidifier is recommended for those days when the temperature doesn’t justify full blown air conditioning. Additionally, look for sources of excess humidity like leaky pipes, standing water, or clothes drying.
  4. Cut the Chemicals – There are a number of high quality household cleaners that don’t contain chemicals. Avoid ammonia, bleach and other chemical laden cleaners that can inflame allergies and pollute the water supply. Your home will be just as clean and you won’t feel uncomfortable afterwards.

Proper cleaning and careful selection of compounds and what goes into your air will help you avoid creating new air quality problems in the house. Done right, this process will make everyone in your home feel more comfortable.

What is R410A?

Wednesday, September 7th, 2011

If you’ve recently started researching a new air conditioner for your Newberg home, you may have run across “R410A” – a newer form of refrigerant increasingly being used in high end air conditioning equipment. What is R410A and why is it different from the existing refrigerant most air conditioners have?

Chemical Composition

R-410A is a composite of diflouromethane and pentafluoromethane. This mixture of R-32 and R-125 creates a new compound designed to be used in commercial and residential air conditioning devices. Sometimes referred to as Puron, Genetron and EcoFluor, R-410A is a more environmentally friendly approach to cooling than the existing coolant most air conditioners use – R-22.

To date, R-22 has been the refrigerant of choice for millions of devices. However, because R-22 will no longer be permitted in new devices starting in 2020, R-410A is growing in popularity rapidly and will soon become the standard refrigerant option in new devices.

Environmental Impact

Despite being very similar in chemical composition to other refrigerants like Freon and R-22, R-410A does not contribute to ozone depletion, a major step forward for air conditioning. However, it has as very similar global warming impact – producing nearly 1725% more damage than carbon dioxide. One of the factors that negates this high global warming risk is the fact that R-410A is being used in a more efficient manner than past refrigerants.

Choosing R-410A

You cannot simply replace the R-22 in your cooling system with R-410A. Because it requires higher pressure, the devices that run with R-410A must be built specifically for this refrigerant. As a result, many manufacturers are starting the transition to the new refrigerant now, in anticipation of the 2020 phase out date for R-22. If you are preparing to buy a new unit, keep this in mind. You can still buy R-22 devices, but they are not as environmentally friendly as this newer form of refrigerant.

Benefits and Disadvantages of Window and Through Wall Units

Monday, August 15th, 2011

When you’re trying to decide what type of air conditioner to get for your Troutdale home, you’ll first have to determine whether a central air conditioning system or smaller individual unit is best for you. These smaller air conditioners are generally installed either in a window or through the wall of your home, and they can provide excellent cooling under the proper conditions.

If you’re still on the fence about what type of air conditioner to install in your home, here are a few items to consider:

  • Ducts – If your home already has ductwork installed for a central forced air heating system, it should be relatively easy to hook up a central air conditioner. But if there are no ducts currently in place, your installation costs will be a lot lower with window or wall mounted units.
  • Portability – Most window units are designed to be removed and stored at the end of the summer, so you can have your windows back and not have to look at that unit all winter long. Through wall units aren’t generally removable, but because they don’t take up window space and provide a more thorough seal against the elements, that’s not as much of a concern.
  • Aesthetics – With both window and through wall units, you’ll have something protruding into your room at least a few inches. These types of units are hard to hide, particularly when compared to the simple air ducts that central air conditioning systems use.
  • Flexible Sizing – No matter how big or small your room is, you should have no trouble finding a window or through wall unit to match it. A central air conditioning system needs to be sized to fit the entire house. If you’re only inclined to use air conditioning in two or three rooms during the hottest months of the year, you may not want to pay to cool the entire house all of the time. Smaller units provide that type of flexibility.
  • Affordability – Installing a central air conditioning system, even if you already have ducts in place, is a large undertaking and likely to cost you several thousand dollars up front. On the other hand, small window and through wall air conditioners are available for as little as $200 and you can buy more whenever you’re ready to spend that extra money. You can also usually install a window unit yourself, and the cost of having a through wall unit installed is minimal compared to that of a central AC unit.

Different Types of Room Air Conditioners

Monday, August 1st, 2011

If you are like most people in Happy Valley, you probably picture the air conditioner hanging out of the window when you think of room air conditioners. However, while these are by far the most popular type of room air conditioners, they are not the only option. When you are shopping for a room air conditioner, it is a good idea to explore all of your options before you make a purchase.

The traditional window mounted air conditioners have plenty of advantages, and that has helped to keep them at the top of the room air conditioner market for a long time. These types of units can be installed in windows of multiple sizes and you can just about always get them in yourself. These units are available in a wide variety of sizes too, so you will be able to match the unit to the size of the space you need to cool.

No matter what type of air conditioner you get, it is very important to make sure it is the right size for the task you have laid out for it. Bigger is not always better and you do not want an air conditioner that is too powerful for the space any more than you want one that is too small. Also, be sure to check the energy efficiency rating of the air conditioner you are considering before making your purchase. That can save you a lot of money over time as well.

Another type of room air conditioner to take a look at is a wall mounted unit. Many of the window mounted units can actually be used in this way as well, but the installation involves actually making a hole in the outer wall of your home so you will most likely need some professional help to get it in place.

Just like window mounted units, wall mounted air conditioners come in all sizes and with all different energy efficiency ratings. Always take care to check out the specifics of the model before you buy it to make sure it is the right choice for your home.

Portable air conditioners are a third option in the room air conditioner category. They typically have wheels so that they can be easily moved from one room to another and they have an exhaust hose that must be hooked up to a window to ensure adequate ventilation. These types of room air conditioners are usually more expensive than wall or window mounted units, but it is definitely convenient to be able to move them from one place to another. If you have more questions, contact your local air conditioning professional.

Freon and Load Capacity – How Are They Linked?

Wednesday, July 27th, 2011

If you’re like most people, you probably don’t think too much about how your air conditioning system works. All you really need to know is that when you switch on the system, your house gets cooler. But if you’re looking to purchase a new air conditioner for your home, it’s a good idea to know how to select the right one to fit the space you’re trying to cool.

Air Conditioning Basics

Air conditioners use Freon as a coolant to remove heat from indoor air and transfer that heat outside. To do this, they cycle the Freon through a closed loop of coils. When the cold Freon enters the cooling coil of the air conditioner, it absorbs heat from the air passing by, thereby lowering the temperature of the air. That cooled air can then be transferred into your home and more warm air can be cycled past the cooling coils.

Air Conditioner Sizing

The more air your air conditioner can cool at once, the larger its load capacity. In order to keep a particular space cool, an AC unit has to have a large enough load capacity to accommodate that type of air volume. A unit that’s too small will obviously never be able to keep your room cool enough, but one that’s too big will have a similar problem.

The truth is that when it comes to air conditioner sizing, bigger is not better. It’s best to simply get as good an estimate as you can of what type of load capacity is ideal for the space you’re trying to cool and stick as close to that as you can.

Load Capacity and Freon

Of course, if you want your air conditioner to cool more air at a time, you’ll need more coolant. But simply increasing the amount of Freon in your air conditioner won’t make it cool any better. Freon is simply one of many elements that contribute to effective cooling. And the larger the entire system is, the more Freon is needed.

So more Freon technically contributes to greater cooling capacity, but it’s not enough to accomplish that all on its own. There is really nothing you can do to increase the load capacity of your air conditioner once it’s in place. So for best results, make sure you pick out an appropriately sized unit the first time around.
