What’s the difference between mechanical and electronic air cleaners?

Monday, September 24th, 2012

There are a number of air cleaners on the market, each of them offering a number of specific features and benefits designed to match the types or air pollutants and allergens your Portland home has. However, a common question we get is about the difference between mechanical and electronic air cleaners.

Mechanical Air Cleaners

Mechanical air cleaners are also called filters and are generally some form of physical device installed in the air flow system for your HVAC device or air handler. The air flows through the filter and particles are removed because they are smaller than air particles. Mechanical filters come in different MERV ratings, and some are rated as HEPA filtration devices, removing up to 99.9% of contaminants 0.3 microns or larger. These devices are highly effective for almost all forms of allergens and contaminants in the Portland area.

Electronic Air Cleaners

An electronic air cleaner uses a different process, actively removing particles by ionizing the air and pulling the particles out of it. The difference is that such a process only works on smaller particles like gas or smoke and fumes. So, an electronic air cleaner removes the stuff that a mechanical filter never could, and is generally only necessary if your home suffers from such contaminants.

When the time comes to have a new air cleaning system installed in your home, the first thing you should do is determine what you need to have removed. Most people will benefit from a mechanical filter upgrade, but if exhaust is a problem due to proximity to a major road or if someone in your home smokes, an electronic filter can go one step further and remove a lot of additional particles.

There are also air purification systems that combine both technologies to create a fully-featured air cleaning system. You can check if this type of system is compatible with your air handler and then have one sized for your needs.

HVAC Repairs That Will Save You Money

Monday, September 17th, 2012

Your air conditioning and heating system operate frequently throughout the year – so much so that regular maintenance and repairs are a basic necessity if you want to ensure absolute comfort for your family year round. There are certain routine repairs or maintenance tasks that can actually save you money though, even if they are not immediately necessary for the proper operation of your HVAC system. Here are a few such repairs and the benefits you will gain.

Clean Your Ductwork

Ductwork cleaning in Portland is an important component of annual HVAC maintenance. We recommend having this done at least once a year to remove the natural buildup of debris and dust in your ductwork that will reduce energy efficiency of your system by as much as 30%.

Clean and Replace Filters

Filters are designed to block debris and dust, among other things, from entering the air flow of your Portland home or from blocking the moving parts in your home’s HVAC system. However, those same filters, when they become clogged, are an equal impediment for your HVAC system. The blocked air flow can not only reduce efficiency but also increase the risk you’ll need repairs.

Calibrate Your Thermostats

Improperly calibrated thermostats can lead to improper cooling and heating in your Portland home, resulting in higher bills or a lack of proper comfort control. These are easy to fix but calibration needs to be done regularly, especially if you have mechanical thermostats. You might also consider an upgrade to a programmable digital thermostat.

Clean the Coils

Dirty coils can be a major impediment to heating and cooling efficiency, as the transfer of heat is blocked by a layer of dust or dirt. Regular HVAC maintenance should include full cleaning of your evaporator coils, as well as your heat exchanger and fan blower motors.

When done regularly the four maintenance tasks above will greatly reduce the cost of operating your HVAC system and save you quite a bit of money over time. Call us today! Portland air conditioning and heating customers can rely on The Clean Air Act, Inc. for quality service.

How Do I Know if I Have a Radon Problem?

Monday, August 27th, 2012

Radon is a gas that is invisible, odorless, and radioactive.  Thus it is important to know if you have a radon problem.  The experts at Clean Air Act Inc. in Portland can help you understand exactly what radon is and how to determine if you have a radon problem.

While naturally occurring, radon usually comes from the breakdown of uranium which happens in soil.  It is also frequently found in areas where granite is present in the soil.  It can be transferred into a building through foundation cracks or even via the water supply.  Once it enters a building it gets trapped and can cause health problems as it is continually breathed in and out.

Some of the main symptoms of radon exposure include repeated respiratory infections, chest pain along with shortness of breath, and a sever cough.  Ultimately radon exposure leads to lung cancer because it is breathed in.  While there are some symptoms associated with radon exposure, it can be hard to truly know whether or not these symptoms are in fact a result of radon exposure, or if they are due to some other environmental problem.

Radon in and of itself is impossible to detect without the proper testing equipment.  The only proof positive way to know if you have a radon problem is to have your building professionally tested for radon.  During the radon testing process, if radon is found, the source of the radon will be identified so that it can be addressed during the radon mitigation process.

There are some home-methods of testing for radon which includes a charcoal canister, an ion detector, and an alpha track detector.  However, these must still be sealed up and sent to a lab for analysis.  Additionally, use of these is not considered completely accurate and it is best to work with a professional when radon testing is concerned so that a complete and thorough analysis can be made.

We are specialists in understanding radon and dealing with it properly, so call Clean Air Act Inc. if you need radon testing and mitigation in the Portland area!

Features to Look for When Buying an Air Conditioner

Monday, August 6th, 2012

Air conditioning systems have come a long way from the loud window units you may remember from years past. If you’re in the market for a new central air conditioner in Portland it can be overwhelming trying to navigate through all the new models and technologies available to you. The important thing to keep in mind is not what the “best” air conditioner features are, but what features are the best for you. New and improved options are only relevant if they’re options that you’re actually interested in. At The Clean Air Act Inc. we want to make sure that you get the air conditioner that’s right for you and your home. Here is some information to give you an idea of what features are available and whether or not you will benefit from them.

Programmability

The ability to program your air conditioner’s output is a great way to fight inefficiency. Programmable thermostats paired with zoning technology will help you cut down on your energy use and reduce utility costs. By breaking your home into cooling zones, each controlled individually from the thermostat, and cooling your home only during the necessary times of day, a programmable system can really reduce the energy and monetary concerns of running your air conditioner.

Versatility

Take into account any comfort issues you know to exist in your home. If your home is consistently, uncomfortably humid, think about an air conditioner with a dehumidifying feature. Should indoor air quality be a priority for you, look into systems that continuously filter air even when the cooling system is off. Fresh air intakes and exhaust settings also allow air to be vented without cooling. With so many options available there is no reason for you to wind up with an air conditioner that will not satisfy all your comfort needs.

Keep Your Home in Mind

When it comes to a home cooling system you must keep your home’s needs in mind as well as your own. If you have preexisting ductwork then a central forced air system will be an easy installation. If you do not have the room for ductwork there are ductless mini split systems available that require only a conduit to connect the outdoor components to indoor blowers. For historic houses, look into small-duct high velocity systems to avoid virtually all renovation. There are enough air conditioning options out there to suit every individual and every home.

A home cooling system is an investment. Don’t rush into a decision. Take your time, consider your options and available features, and get the air conditioner that’s right for your Portland home. The Clean Air Act Inc. is here to answer any questions you may have, so call us anytime.
