Sources of Carbon Monoxide: A Guide from Issaquah

November 14th, 2011

The risks of carbon monoxide have been well documented for years, and everyone in Issaquah knows how dangerous it can be. CO can be fatal at high concentrations, but even in low levels it can be poisonous enough to make you sick.

What you may not know is that there are many sources of carbon monoxide, also known as CO. This poisonous gas is formed by any incomplete combustion process. Since combustion is not 100% efficient, that means carbon monoxide is released any time something burns.

To be more specific, here are some examples of carbon monoxide sources you might encounter around your house:

  • A furnace or chimney can leak exhaust gases, including CO, into the home if it has been improperly sealed or vented. For example, if the chimney has a small crack in the flue that goes unnoticed, CO from the fireplace can be vented back into the house.
  • A furnace supplied by an under-sized gas line will often burn the gas at a sub-optimum temperature. The result is incomplete combustion of the gas, which means a source of CO.
  • Old, dilapidated or poorly maintained heating systems are a big culprit. Often the seals or fittings are loose on these units, causing CO to leak out of them and into your house. Or they may not burn fuel as efficiently as they used to, so carbon monoxide is more readily released.
  • Using machinery, like a propane generator or a gas-powered saw, in a poorly vented garage can be very dangerous. Sometimes people don’t think about this one because the garage is large enough that it seems to be ventilated better than it is.
  • There’s a reason that barbeque grills are labeled for outdoor use only: they release a lot of carbon monoxide. Both charcoal and propane grills should only be used outdoors, and you should avoid the smoke from charcoal in particular as much as possible.
  • Smoking tobacco releases carbon monoxide into the air, along with other potentially dangerous gases.

There are plenty of other sources, as well, but those are some common ones. To protect yourself and your family, make sure any areas where combustion occurs are well-ventilated, keep your HVAC equipment well-maintained and in good repair and invest in a home CO detector. They are inexpensive, and many are combined with a smoke detector, so you only need to buy one unit.

How to Clean the Parts of a Heat Pump? A Question from Yelm

November 11th, 2011

It is very important to keep your heat pump clean. It improves efficiency, helps performance and prevents malfunctions. Cleaning your heat pump should be part of your Yelm home’s maintenance routine in order to keep the house as comfortable and worry-free as possible.

That is all well and good, but how do you go about cleaning the components of your heat pump. It’s one thing to advise you to clean, clean, clean…but it doesn’t do much good if you do not know how. To correct that, here are some tips to help you clean the different parts of your heat pump.

Caution: before doing any maintenance on your heat pump, including cleaning, be sure to turn off the power to the unit. This is a necessary safety measure.

Filters

  • If you use disposal air filters in your heat pump, skip this part. Just make sure to change them regularly, in accordance with the manufacturer’s instructions.
  • To clean air filters, follow the directions of the manufacturer that were included with the filter. This is also a good time to double check that the filters are installed properly.
  • Clean or replace your filters monthly during heavy use seasons, such as the warm summer months and cold months of late fall and winter.

Coils

  • Remove any debris from the outside of the coils and the surrounding area. Sticks and leaves may have accumulated near the outdoor coils, so just brush them away.
  • Using a soft brush attachment, vacuum the exterior of the coils. Take care not to bend or dent the coils.
  • Using a hose with a spray attachment, flush the coils with water from the inside out. This will remove any stubborn debris. Take care not to spray any electrical components, such as the fan or any nearby wires.
  • While you are inside the unit, vacuum the bottom inside to get rid of any more stray debris.

With that done, put everything back, replace the grille covers and power the heat pump back on. It should run smoothly with a fresh filter and no debris to gum up the works. Clean the coils every few months to keep the heat pump in tip top shape.

Pros & Cons of Heat Pumps: A Guide from Bonney Lake

November 9th, 2011

When deciding on any major purchase in Bonney Lake, a critical step is to weigh the pros and cons. This helps you to decide on the best option and reach the best decision for your needs and preferences.

Installing a new heating system is a perfect example of a situation in which you would need to weigh pros and cons. There are a lot of options, and not all of them are right for all people. Take heat pumps, for example. They are great devices and serve many people extremely well as home heating solutions, but they are not without their drawbacks. Below are some of the pros and cons of heat pumps to help you decide whether a heat pumps if the way to go for you.

Pros:

  1. Inclusive – A heat pump not only heats your home in the winter but also cools it in the summer, thanks to a reversing valve that changes the flow of the refrigerant. Having one appliance for both heating and cooling can be very convenient.
  2. Energy efficient – Heat pumps are extraordinarily efficient when it comes to energy use. Because they simply move and distribute heat, rather than producing any on their own, they use minimal electricity.
  3. Simple – Operating on the same basic principles as your refrigerator or an air conditioner, heat pumps are relatively simple. More importantly, they simplify your life by putting your heating and cooling solutions in one package and running on electricity, so you don’t need any other fuels on hand.
  4. Inexpensive to operate – In addition to being energy efficient – which lowers your monthly energy bills – many heat pumps are eligible for federal tax credit. You can save a bundle by using a heat pump.

Cons:

  1. May need supplementing in cold climates – In climates where winter temperatures stay below 30 degrees Fahrenheit for a while at a stretch, a heat pump will have trouble keeping up and need to be supplemented.
  2. Don’t work in power outage – Obviously, because they are powered by electricity, a heat pump won’t work in a power outage, unlike some other heating solutions that do not require electricity.

Although the pros clearly outweigh the cons here, the cons are important as well. Carefully consider all these factors and more while deciding whether a heat pump is the solution for you.

What Happens if My Heat Pump Loses Power? A Question from Edgewood

November 7th, 2011

One of the advantages of having a heat pump in your Edgewood home is that they operate on electricity, so you don’t need to worry about having maintaining a supply of fuel to keep yours running. Where a furnace or boiler might call for you to purchase supplies of oil or natural gas, and a wood stove means keeping potentially messy firewood around, a heat pump runs cleanly on electricity.

Heat pumps are good at using electricity, too. They are often able to produce heat energy that can be as much as three times the electricity they draw to produce it. This means not just convenience, but also a big savings, just by virtue of using electrical power.

The risk there, of course, is that if and when the power goes out, so does the heat pump. That means when a big winter storm drops a tree on the local power line, things can get cold inside mighty quickly. For these situations, you should have a backup heating solution on hand to keep everyone comfortable in the short term. And, as a responsible homeowner, you likely already have this taken care of.

But what happens when the power comes back on? Can you just fire your heat pump right back up without missing a beat?

The short answer is “no.” You should not do that, for at least two reasons. First of all, after any power outage, you should always take care to turn on appliances gradually over a period of time rather than all at once in order to avoid a spike in demand at the power company, which can blow a grid. That’s just a general tip.

Specific to heat pumps, though, there is a unique concern. If the heat pump loses power for more than 30 minutes, the refrigerant can get too cold to flow properly, so turning it right back on can cause the whole thing to conk right out. Instead, do the following:

  1. Make sure the heat pump is off. You can do this during the power outage.
  2. Once power comes back on, turn the heat pump to the “Emergency Heat” setting. This will allow the compressor to warm up slowly and get the refrigerant warm enough to start flow freely again.
  3. Wait. The time you need to wait varies depending on the size and manufacturer of your heat pump, so refer to the manual. In general, you should wait at least 6 hours.

After this process, your heat pump should be ready to resume normal operation without issue.

Heat Pump Maintenance: Some Pointers from Seatac

November 4th, 2011

Heating and cooling your Seatac home is a priority. You need your home and family to be comfortable all year round, so you either got or are considering a heat pump. These machines are great because under the right circumstances, they are essentially all-inclusive and incredibly efficient solutions for all your home heating and cooling needs.

Notice the “under the right circumstances” part. A number of things have to be considered when choosing a heat pump, such as the climate and the size of your home. But these are not the only circumstances that influence how well your heat pump works for you. Proper maintenance is a vital component of heat pump ownership, ensuring that you get the best performance out of your heat pump for the longest time possible.

A major part of properly maintaining any machine is to keep it clean. A heat pump is no exception. Dirt and dust can affect the efficiency of your heat pump, as well as speed up corrosion problems. Keep the compressor and coils clean. Check them monthly or so and remove any accumulated dirt. Also, consistently check and change filters according to the manufacturer’s recommendations.

Simple cleaning is an easy and effective first step to heat pump maintenance, but there are some things that you just won’t be able to do on your own. For more intensive maintenance, it is best to call in a professional for an annual inspection.

During a routine maintenance check of your heat pump, a technician will inspect the whole heat pump system for problems. He will clean the compressor and coils, tighten any connections that may have loosened up and change the filters as needed. In addition, a skilled technician will be able to detect any early signs of trouble and make necessary repairs to prevent break downs. These small repairs can prevent big problems later on, thereby preventing some serious discomfort and a possible big expense.

If you are considering a heat pump as a heating and cooling solution for your home, great. If you have already decided on one and had it installed, congratulations on making a smart decision. Now, make another smart decision to protect that investment by keeping your new heat pump properly maintained.

What is the Emergency Setting on My Heat Pump? A Question from Lacey

November 2nd, 2011

While installing or inspecting your Lacey home’s heat pump, you may have noticed that little switch or button labeled something like “Emergency Mode.” And then, you probably scratched your head and thought, “what is that for?”

Hopefully, the emergency setting is not something you will ever have to use. But, it is there for a reason, so it’s possible you may have to resort to it at some point. In that case, it makes sense to know what it is first.

The emergency setting on your heat pump interrupts the normal operation of the device. The compressor shuts off, so the heat pump no longer pumps heat from the outside into the home. Instead, the internal heating element is activated. This backup system is designed to provide a sufficient, albeit minimal, amount of heat when the heat pump is not working properly. The idea is that the element can keep your home warm enough while you get the heat pump fixed.

That’s what the emergency setting is, but when would you use it?

It’s not a trick question. As the name implies, you only want to use this setting in an emergency. For example, if the heat pump has frozen and isn’t operating, the best course of action is to switch on the emergency mode and call a professional to repair it.

You would also want to use the emergency mode when recovering from a power outage. Any time a heat pump is without power for more than thirty minutes the refrigerant can cool and get too thick to properly flow through the coils. Turning the pump back on in this situation can damage it, so instead you would use the emergency mode for a while to warm the refrigerant back up, then return to operating the heat pump normally.

The emergency setting is not to be used in place of a supplemental heating system. If there is an uncharacteristic cold snap, and your heat pump can’t keep up, then it makes sense to use the emergency setting to keep the house warm. However, if you live in a colder northern climate, where temperatures routinely drop below 30 degrees in the winter, you should have a supplemental heating system in addition to the heat pump. Using the emergency heat setting regularly is not a good idea.

How to Get the Best Heat Pump in Tukwila

October 28th, 2011

Happy Halloween weekend from everyone at Sound Heating & Air Conditioning! We hope you have a fantastically spooky time! But buying a heat pump shouldn’t be scary, even around Halloween. Here are some tips on how to choose the right heat pump for your Tukwila home.

But how do you decide what the best option is, especially when choosing a product that you know little about, like a heat pump? The average homeowner does not spend a lot of time studying his heat pump or reading heat pump magazines for fun, so chances are you are not a heat pump expert. That’s understandable…but it doesn’t help you when you are trying to buy a new one and you want the best.

Fortunately, there some things you can look for to get clues about the quality of a heat pump and how well it suits your needs. Read on to learn more about these indicators in brief.

Efficiency is among the most important factors in choosing a heat pump. Because heat pumps can be used for both heating and cooling, they have two different efficiency ratings, one for each mode.

The heating efficiency for a heat pump is rated on a scale called the heating season performance factor (HSPF). This rating is actually the result of a calculation. To find the HSPF for a heat pump, the unit’s estimated heating output is divided by its energy consumption. Simply put, it’s the ratio of heat put out by the unit to the amount of power it draws. The higher the HSPF, the more efficient the heat pump is. To give a frame of reference, all new heat pumps are required to have an HSPF of at least 7.7. The most efficient units available carry an HSPF of 10.

The rating system used to convey the cooling efficiency of a heat pump is the seasonal energy efficiency ratio (SEER). This is a simple numeric value that rates how efficient the unit is. Many new heat pumps carry a SEER of at least 12, while the most efficient models rate between 14 and 18.

While efficiency is important, it is just one factor. More efficient units are also more expensive, so you will want to consider the upfront cost. The most efficient units will pay for themselves in savings relatively quickly, but the purchase price is still important. Be sure to weigh all the pros and cons when choosing a new heat pump. And if you have any questions, talk to your local contractor.

How Indoor Air Quality Controls Can Help People with Asthma: Some Pointers from Olympia

October 26th, 2011

If you, your child or anyone else in your family suffers from asthma, you know that it can be brutal. The shortness of breath, the wheezing, and the chest tightness—it’s not just uncomfortable; it can be downright scary.

There is evidence to suggest that higher quality air can help keep asthma symptoms in check. While you can’t control air quality everywhere you go, you can be in charge of the quality of the air in your own Olympia home. Take a look at how controlling indoor air quality can help ease the suffering of asthma symptoms.

One study at Johns Hopkins found that indoor air pollution plays a large role in increasing asthma symptoms, especially among children. Without getting too technical, essentially the study explains that there are particles in the air we breathe, including indoors. Aside from the standard mixture of oxygen, carbon dioxide and other gases, air contains these solid and liquid particles, which are essentially pollutants. Common household tasks like dusting and cooking can generate more of these particles.

When these particles get into the respiratory system, they can irritate the lungs, which triggers asthma symptoms. Since children spend about 80% of their time indoors, this is a very big deal.

To help this problem, there are ways to control and improve the quality of air in your home. One simple way to do this is to have filters with high minimum efficiency reporting value (MERV) ratings in your heating and cooling system. MERV ratings describe how well filters catch particles of certain sizes and keeping them out of the air—and your lungs.

The particles identified in the Hopkins study were as small as 2.5 microns, which would require a filter with a MERV rating of about 12 to catch. Higher MERV ratings mean more efficient filtration, but they need to be replaced more often. If you or child has asthma, it’s worth it.

For severe asthma or allergies, consider even higher-rated filters, like HEPA filters, which sport a MERV of 17 or higher. These will catch nearly all allergens, irritants and other particles that can make you sick.

Plants & Indoor Air Quality: A Tip from Tacoma

October 24th, 2011

In our Tacoma elementary school, we were taught that plants are the “lungs of the Earth.” They remove carbon dioxide from the air and release oxygen, which is great because it is the exact opposite of our respiratory process. They also clean the air in the process, like natural air pollution scrubbers, improving the quality of the air around them.

Given this, it’s not surprising that people have sought to harness the respiratory power of plants to improve air quality in their homes. One study by the National Aeronautics and Space Administration (NASA) in the 1980s even identified the best plants for improving indoor air quality.

This seems like great news for people who suffer from asthma or allergies, or who just want a natural way to purify the air in their homes. However, plants are not without their drawbacks. It is not a simple as to just bring a plant into the home. A plant is really an entire ecosystem, with many other organisms latched on for dear life. There are bacteria in the soil, for one, and there may be bugs or fungi in the soil or on the plant that you can’t even see.

Most of these are harmless, but not always. The fungus can be a problem, for example, if the spores get into the air. This can make allergies and asthma worse, not better.

That doesn’t mean you have to toss out that nice spider plant or Boston fern in the garbage, however. After all, it is probably doing a great job of filtering out some inorganic pollutants, it’s increasing the oxygen concentration of the room and it looks nice. Instead of getting rid of it, just give it a partner.

Adding an air cleaner like a fan with a filter can help purge the organic gunk that may be coming from the plant, while the plant is taking care of the other stuff. The result is cleaner, better air, which can be a relief to asthma and allergy sufferers.
