How Tightly Should You Seal Your Home?

Thursday, March 22nd, 2012

More and more products, like high velocity heating systems, and solutions are available to Welches residents these days to help seal our homes off from the outside world. The idea is that by keeping outside air out, our homes are more energy efficient and healthier, because all pollutants and pathogens are barred from entry.

This is a good idea in theory, but it can have its drawbacks. Most notably, sealing your home up too much can be bad for your family’s health. If your home is sealed too tightly such that there is not enough air flow from within the home to the outside and vice versa, then the indoor air just…stays indoors.

That means that all the sneezes, coughs, dust, dander, smoke and carbon dioxide stay inside with it. All that stuff can make you sick, completely flying in the face of your efforts to stay healthy by sealing your home.

Now, that’s not to say that sealing your home is a bad thing. Using LEED glass in your windows does keep heat in and increase heating efficiency. Air cleaners do help eliminate pollutants and pathogens from the outside than can make you sick. Good insulation and intact ductwork do help keep your home comfortable and efficient in both the cold and hot months.

So, sealing your home is not a bad idea. The trick is to not go overboard and seal it up so tightly that you are crossing the threshold from having a healthy home to having a giant Petri dish. You want to have a home that is insulated, but not vacuum sealed. You want a home with filtered air, but still plenty of air exchange with the outside world. Thankfully, mechanical ventilation is a way to both keep your home energy efficient and keep your indoor air from getting stale.

To help you with this endeavor, there are guides available online, such as at the ENERGY STAR website. In addition, it is a good idea to call The Clean Air Act and ask plenty of questions when building a new home or making improvements to your current one. A qualified technician will know how to insulate and ventilate your home properly to protect your family’s health.

The Danger of Refrigerant Leaks

Friday, March 16th, 2012

In Heath your air conditioning system is filled with a chemical compound called refrigerant. This substance is what allows your air conditioner to remove heat from and dehumidify your home. It is a necessity, but it is also a dangerous chemical that, if released, can cause damage to the environment and pose health risks to your family.

Why Refrigerant Is Dangerous

There are many types of refrigerant but most air conditioners use either R-22 or Freon coolant – depending on their age. If you have received an air conditioner installation recently you may be using R410-A refrigerant, an environmentally safer, but still dangerous alternative.

All of these refrigerant types are chlorofluorocarbons or CFCs. These chemicals are controlled substances by the Environmental Protection Agency, meaning they must be properly removed and disposed of. Because your air conditioner does not consume any of coolant in operation, it should never need to be refilled unless there is a leak. Such a leak should be stopped immediately due to the immense damage CFCs can do to the environment.

If refrigerant leaks into your home it will evaporate as a gas and is harmful to inhale, causing a variety of health problems, including nausea, headache and in extreme cases asphyxiation. This is not a common occurrence but if you suspect a leak, you should call a professional immediately to inspect your air conditioner.

Damage to Your Air Conditioner

Beyond the environmental and health issues posed by a refrigerant leak, the biggest problem you will face is damage such leaks can cause to your air conditioner. Low refrigerant levels put undue stress on your compressor and can lead to damage in almost every part of the device.

Not only that but the air conditioner won’t work as efficiently. A 10% loss in refrigerant volume can result in up to a 20% increase in electricity cost to run your air conditioner.

What to Do in the Event of a Refrigerant Leak

If you suspect a refrigerant leak in your air conditioner, take action immediately. If you are in Portland, OR call Clean Air Act and they can recapture the escaped gasses and seal the leak fast. It is important not just for your safety but for the well-being of the environment.

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.

Should I Use Propane, Oil, or Natural Gas to Heat My Home?

Wednesday, February 22nd, 2012

In most cases, you’ll have a choice concerning what type of fuel you’d like your furnace to burn in a Portland home. For most people, this choice comes down to propane, oil or natural gas. The one you choose could significantly impact the cost of heating your home for many years to come, but it’s usually a pretty clear cut decision.

One thing to remember is that most furnaces installations that burn natural gas can also burn propane. If you don’t yet have a propane tank but are considering getting one, you might not have to make a final decision just yet. Although it’s generally better to set up your furnace for one type of fuel and then leave it that way, you will likely still have the option of converting later on if you should choose to.

If you do have access to natural gas, though, that’s probably going to be your best option. Furnaces that burn natural gas or propane are generally much more efficient than any other type of furnace on the market. You can get them with annual fuel utilization efficiency (AFUE) ratings as low as 80% and as high as 97+%, so that ensures that you’ll be able to find the one to fit your specific situation.

If you’re facing particularly harsh and frigid winters, you’ll want to choose the most energy efficient option available to you and that’s pretty much always going to be a natural gas furnace. Of course, when you’re looking to decide between natural gas and propane as a fuel source, you’ll just want to compare the relative cost for each in your area. For some people natural gas is cheaper, while it’s propane for others. And since your furnace will operate at the same efficiency no matter which of these fuels you choose, you just need to choose the cheapest.

Oil is certainly an option as well, but if you’re looking for a very high efficiency furnace, you’re not going to find one that burns oil. That doesn’t mean that an oil burning furnace might not be a good investment for you. If you don’t have access to natural gas in your area and your heating load isn’t that high, oil might be a perfectly economical choice for you.

If you do opt for a super high efficiency furnace, but don’t have access to natural gas lines, propane is probably the way to go as opposed to oil. If you have any questions about different heating options please call The Clean Air Act.

Things to Look for When Buying a Heating System

Friday, February 17th, 2012

If you are in the market for a new or replacement heating system in Gladstone and don’t know much about heating systems, you are not alone. Many homeowners are in the same boat as you. And many of that number put their trust in their local, professional, and qualified heating and cooling contractor to find the right furnace for their homes.

Before calling for an estimate, there are some things you can do to “prepare” yourself for one of the most important purchase you can make. Here is a checklist of things you should look for when buying a heating system.

Know your energy alternatives. There are lots of options today when it comes to heating your home. Gone are the days when the choices were so cut and dried. Check with your heating and cooling contractor for suggestions.
Know what size your furnace should be. Furnaces are not “one size fits all.” The size of the furnace is determined by its Btu (British thermal unit) rating. For example, a one-story ranch home on a crawl space requires less heating capacity than a two-story colonial with a basement, thus it would require a furnace with a smaller numbered Btu rating. A home with a great deal of heat loss through windows and doors may require various furnace sizes. And don’t forget about insulation. Insulation can affect the furnace size, too. Again, check with your heating and cooling contractor for recommendations.
How much room do you need for your furnace? Some homes have mechanical rooms for furnaces and water heaters while others utilize attics, basements, or crawlspaces for furnaces. If you think you need a big furnace to heat a big home, think again. Furnace manufacturers have been downsizing their heating equipment for years, while maintaining the same heating capacities. One example are wall hung boilers, which utilize water and electric as heating sources and are installed on a wall, making the unit easy to locate and easy to service – while at the same time being off the floor and out of the way.
Will your heating system be “plug and play?” New furnaces can take the place of the ones they are replacing by using the same space. But sometimes a replacement unit may need some altering to fit into an existing duct system. It is almost a given that a new plenum (the part attaching the furnace to the ductwork) will have to be fabricated. But the new furnace may also require some other modifications to an existing duct system. You should understand this ahead of time and be prepared to pay additional costs.
A box is a box is a box. As a rule, most heating systems are made the same. In some cases, one furnace manufacturer may produce several different brand names. The best “brand” is the heating and cooling contractor who installs and services your heating equipment. Do your homework ahead of time and find a qualified and professional contractor. Ask friends and family for recommendations. This is may be the most important thing to look for when buying a heating system

If you have any questions about this article please give Clean Air Act a call.

Crawlspace Heating Tips

Monday, February 13th, 2012

Keeping your crawlspace warm and insulated in Washington County might not seem like something that should be at the top of your priority list. However, if you really want to find ways to save money on your heating and cooling bills and keep your home as comfortable as possible, it’s definitely something you should look into.

The crawlspace of your house is generally located beneath the floor and since it’s not someplace that you’re likely to spend much time, it’s generally not insulated or sealed against the elements very securely. In some cases, heating and cooling ducts and pipes carrying hot water can run through the crawlspace as well.

The lack of insulation in the crawlspace of your house can impact your indoor environment in a couple of ways. First of all, it often means that your floor is cold to walk on and that cool air can seep in through any cracks there might be in your flooring. This infiltration of cooler air means that your home heating system will have to work harder to maintain a comfortable temperature inside.

Also, the air and water traveling through the ducts and pipes in your crawlspace will be losing heat as they go, so you won’t be getting all of the heat you’re paying for on that end either. Adding insulation in your crawlspace is the best way to keep from losing heat in this way. It’s generally not a huge investment and it will save you quite a bit in the long run. It can also help your heating system last longer because it won’t have to work so hard to keep your home warm enough.

If you live in an area with relatively mild winters and hotter summers, you might think that investing in some crawlspace insulation wouldn’t be worth it for you. But the truth is that you can save just as much by keeping your cool air inside in the summer as someone in a cooler climate can by keeping hot air inside in the winter.

And insulating and heating your crawlspace isn’t just about keeping the rest of your house warm. It can also help to keep moisture problems from developing. An excess of moisture in your crawlspace can quickly allow mold to develop and too little moisture is damaging to wood and can cause your heating system to function less effectively overall. If you have any questions about these issues please contact Clean Air Act.

How Do Electronic Air Filters Work?

Friday, February 10th, 2012

For a long time, the most frequently used kind of air filter in Fairview has been the mechanical variety. This is the kind you probably think of when you hear the terms air filter, air cleaner or air purifier. They use pleated fibrous filters in-line with an air handler to trap particles in the air before circulating it back out into the home.

Many models of these work very well and have for many years. They have the added benefit of being flexible because you can put in whatever filter you need depending on what size particles you need to trap.

However, these traditional devices are not the only option. A second kind of air filter exists for trapping particles in the air– one that does not use a fibrous filter that physically snags them out of the air on the way through.

These electronic air filters work in a different way to produce a similar result. The filtering component is still a fibrous sheet, but the difference is that the fibers are made of plastic, which becomes charged when air passes through it and causes friction.

(Think something like when you rub a balloon and stick it to the wall.)

These friction-charged fibers carry an electronic charge, which attracts the ions in the air around it. These ions — and the particles that they are a part of — get trapped in the fibers and stay out of your air supply.

Electronic air filters are generally very good at trapping particles that are 1 micron in size or higher, putting them about on par with a mechanical air filter that carries a MERV rating of 12. The electrostatic method works well for many common household air pollutants, such as dust, pollen, mold and pet dander.

As with many ventilation-related decisions, the choice of what kind of air filter is right for you depends on your needs and those of your family. If you are having trouble deciding, then an air quality assessment and consultation with a professional can be a good way to reach a decision. If you need any help with this decision please contact Clean Air Act AC.

What Does an Air Handler Do?

Wednesday, February 8th, 2012

A Portland resident’s HVAC system is a complex system filled with vital components tasked with keeping you comfortable. One of the most important of those component is the air handler – the device responsible for circulating the heated or cooled air produced by your system through the vents in your home and into each of your rooms.

The air handler is a metal box, usually consisting of a blower and the heating or cooling elements. It might also include dampers and sound attenuators along with an air filtration and humidity control system. The simplest air handlers are designed only to transfer the heated or cooled air to the various parts of your home, while the most advanced devices are designed to perfectly condition and clean that air as it is circulated.

Types of Air Handler

There are a few different types of air handler as well, depending on the size of the HVAC system and the nature of the heating and/or cooling used. Most homes, for example, use terminal units which consist of just an air filter, blower and coil. This very simple system is all you really need to heat and transmit air through your ductwork.

However, for larger systems, there are also makeup air units which use outdoor air instead of recirculated indoor air. There are also packaged and rooftop units which are designed to be placed outside. These devices are most commonly used for commercial applications when space is limited.

How the Air Handler Works

An air handler’s most basic component is a blower fan. This device is run by an AC electric motor and can be either single speed or variable speed depending on the size and scope of your air handler. The dampers on the fan will control the flow rate of the air going through the blower fan. Most residential blowers are part of the air conditioning or furnace system, while commercial systems often have multiple blowers to maintain steady airflow for a larger space.

Because an air handler passes all of the air that will go through your vents, it is the best place to install high quality MERV or HEPA filters to remove pathogens and contaminants. It is also a good place to install humidity control devices to either raise or lower humidity depending on the time of the year.

Your air handler is an incredibly important component in your home heating and cooling system. Without it, all that heated and cooled air you pay for each year wouldn’t reach you. So, make sure to keep your system in tip top condition. If you have any questions about your heating and cooling systems please contact Clean Air Act Heating and AC experts

Preventative Maintenance For Your Home Heating System

Monday, February 6th, 2012

Ben Franklin once said, “An ounce of prevention is worth a pound of cure.” His famous quotation can apply to many things in life, including the heating system in your home. While heating systems in Ben Franklin’s time consisted of wood burning stove and fireplaces requiring little maintenance, today’s sophisticated furnaces and building controls require a good dose of preventative maintenance in order to avoid mechanical failures and inefficient operation.

For example, a furnace runs better and lasts longer when you maintain a regular schedule of filter cleaning or replacing. A dirty or clogged filter can restrict airflow from the furnace into your home’s ventilation system and cause the furnace to work harder, putting more wear and tear on it and taking months, if not years, off of its useful life. If your furnace uses disposable filters, check them every month and replace them if necessary. If your furnace uses an electronic filter that requires cleaning, check it on a monthly or semi-monthly basis and clean it with soapy water and a hose. Be aware of the change of seasons which could add extra pollutants into the air like pollens, ragweed, and cottonwood. This debris easily finds its way into the filters and creates an unhealthy indoor environment.

You can also perform a simple visual inspection of working components inside your furnace by removing the access cover and checking – with a flashlight – for loose fan belts, frayed electrical wires, or a build-up of dirt and dust. Simple solutions include tightening or replacing belts, repairing wiring, and vacuuming out dirt and dust with a hose attachment. All of these actions will keep your furnace working better and prevent future failures.

You can also do a visual check of your home’s ventilation system, paying close attention to any cracks in duct seams or holes in flex ductwork. Using sealing cement or duct tape can usually fix these problems and allow for better, unrestricted air flow. Again, these actions will help your furnace work more efficiently and avoid premature failures.

Maybe the best advice for preventing heating system breakdowns is to have a regular maintenance schedule with a local qualified heating contractor. Most contractors can set you up with annual furnace and ventilation system inspections. Having a service agreement – as a rule – gives you priority emergency repairs and discounts on parts and services. Besides that, planned maintenance is also preventative maintenance, something that will give you peace of mind in the long run. Please contact your HVAC experts at Clean Air Act if you have any questions about these preventative maintenance ideas.
