Top 5 Reasons to Install an Indoor Air Quality System

October 8th, 2012

We spend a lot of our time indoors—whether it’s sleeping and eating or just relaxing with our friends and family. In Portland, we tend to have pretty clean air. But what you may not realize is that your indoor air is often more polluted than the air outside. In fact, poor indoor air quality is the fourth largest environmental threat to our country, according to the EPA. Here are a few reason why you should invest in an indoor air quality system:

Allergy relief

For any of your family members who suffer from allergies, having an indoor air quality system can trap pollen and pet dander that would otherwise irritate them. Indoor air cleaners like media filters, electronic and HEPA filters are specifically designed to capture exactly those kinds of contaminants. Installing an air cleaner in your air handler may reduce the effect that pollen and pet dander have on your family.

Reduces amount of dust and contaminants in the air

Dust can also be a respiratory irritant and can accumulate on your furniture. Media filters installed in your heating and air conditioning system can trap dust and remove it from your indoor air leaving your house cleaner. Electronic air cleaners ionize the air to filter out smaller particles like smoke and exhaust fumes.

Removes bacteria and viruses

Electronic and HEPA filters can also capture microscopic bacteria and viruses before you can even breathe them in. This can reduce the number of illnesses that occur in your home. Additionally, an ultra-violet germicidal light can further increase the purity of your home’s air by killing germs inside your ductwork before they can recirculate into your home.

Allows fresh air inside

Part of a good air purity system is to make sure it is properly ventilated. By increasing the “tightness” of your home—how much air your home lets in—you can control exactly where the air in your home comes from. By properly ventilating your house, you can continually cycle in fresh air from outside.

Keeps humidity constant

A house that has too much or too little humidity can cause you a lot of problems. With too much humidity, your house can become a breeding ground for mold. It can also make it difficult to breath in your house. But too little humidity can cause your nasal passages, skin and even your furniture to dry out and crack. With a humidity control system from Clean Air Act, you can kep your humidity at the perfect level—around 30-50%.

Proper Ventilation for Improved Indoor Air Quality

October 1st, 2012

When you think about your Portland home’s furnace, you’re probably not thinking about indoor air quality. But the truth is that there are several ways in which your furnace can impact the quality of the air in your home. When you have a furnace in your home, it’s important to understand the relationship between these heating systems and your home’s indoor air quality.

Proper Ventilation for Byproducts of Combustion

Especially if you have a gas furnace, you need to be aware of the gasses that are produced by the combustion of natural gas to generate heat. The two that are the most relevant to indoor air quality are carbon monoxide and formaldehyde. In a furnace that’s working properly and is well maintained, these gasses will be kept from the living spaces of your home and vented outside where they can disperse and are not harmful.

Air Filters

In addition to venting fumes outside, your furnace also should have air filters that can remove all types of indoor air contaminants that may be found in your indoor air. These air filters are a great way to keep the quality of your indoor air high, but they also need to be changed out or cleaned on a regular basis to ensure they’re working properly and that you’re getting all of the benefit you should from them.

If you have a particularly severe indoor air quality problem, or if anyone in your home has asthma or allergies, you may want to invest in an upgrade to the stock filters that come with your furnace. Opting for a higher quality filter can dramatically improve the quality of your indoor air.

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

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

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.

Where Are Air Cleaners Installed and How Do They Work?

September 10th, 2012

Just from reading the name, most people in Oregon City can figure out what whole home air filtration systems do. But what many people don’t know is where they are placed in your house and how they actually filter the air. There are many different kinds of home air filtration systems and each one cleans your air in a different way.

Mechanical Air Filters

Air filters are installed as part of your heating and air conditioning system. They are most commonly installed in the air handler that distributes clean air to the rest of your house. As the air passes through the filter, particulates, bacteria and viruses, pollen, pet dander and other contaminates are trapped and removed from your air supply. Depending upon your needs, the filters come in varying sizes: some are designed to filter very tiny contaminates like viruses, while others are made to trap larger particulates like dust. Ask the experts at Clean Air Act, Inc. which filter is right for your Oregon City home air filtration needs.

Electronic Air Filters

Electronic air cleaners differ from mechanical air filters in that they use an electronic charge to trap particles similar to the way static electricity works. There are several types of electronic air filters. Electrostatic precipitators are installed in your air handler where they draw air across an ionized section of the filter and attach a positive electrical charge to the particles in the air. These charged particles are attracted to, and accumulate on, negatively charged collector plates.

Ion generators, another type of electronic filter, work in a similar way but without the collector plates. These devices emit charged ions into the air where they attach to other particles and collect on objects like furniture, walls or the ground.

When to Replace Parts of Your Geothermal System

September 4th, 2012

A geothermal system isn’t much different from other Portland heating and air conditioning systems in that it will require regular preventive maintenance visits, may need repairs on occasion, and eventually certain components will need to be replaced. But when will those replacements be needed and how will they compare to the frequency of part replacement on systems such as those for a furnace or air conditioner?

 The Condenser

A geothermal system may draw heat from a unique source, but the technology used to extract that heat and distribute it throughout your home is largely the same as in a traditional heat pump or air conditioner. So, you will have a condenser unit outside your home, coils inside your home and an air handler to distribute the air that is heated or cooled.

Each of these components needs to be properly maintained over a period of time to keep it from breaking down but there will be times when certain things need to be replaced. For reference, the average condenser unit has a limited warranty of up to 10 years. The system will likely last beyond that if well maintained, but it will probably need replacement sometime between 10 and 15 years of age.

Your indoor coils will likely last longer, though if they are not cleaned properly or if your system runs a lot, they may need replacement between 15 and 20 years. The air handler is different because different models are rated for different lengths of time, but it should be inspected and checked as often as your condenser and replaced when it gets old.

 Other Components

For the most part, the piping installed under your property to gather geothermal energy is likely going to last for many years – between 20 and 30 in most cases. However, there are situations in which piping may need to be replaced. Root growth from a nearby tree, damage from a natural disaster or improper installation of the system can all lead to early replacement.

Whatever your Portland geothermal component replacement needs, make sure you take action as soon as you suspect a problem to minimize the potential cost of such replacements. Call The Clean Air Act, Inc today for service!

How Do I Know if I Have a Radon Problem?

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!

How Do Limit Switches Work in Air Conditioning Systems?

August 20th, 2012

Your air conditioning system has a lot of components which work together to cool your home.  Here is some information about the limit switches in your AC to help you better understand its operation, and to let you know when you need to call a Gresham AC technician.

What are Limit Switches?

Limit switches are used in a variety of devices for both commercial and residential applications.  Limit switches are created with two main purposes in mind.  They control electrical circuits by either activating or deactivating them, starting or stop specific electric pulses. One of the easiest examples to understand is the light which automatically turns on when the fridge door is opened, and which shuts off again once the door is closed.  Most of the time limit switches are kept out of site, and in fact we often don’t even know when they are in use.

How Do Limit Switches Work in Air Conditioning Systems?

AC limit switches are quite common.  The main example is the link between the air handler blower and the thermostat.  When the thermostat reaches the preset indoor temperature an AC limit switch is flipped. This stops the air conditioning system from creating any more cold air.  An additional AC limit switch turns off the air handling unit simultaneously so that warmer air that has not been cooled does not continue to blow through the vents.  When the temperature read by the thermostat rises once again, both air conditioning limit switches are flipped back on, creating cold air and blowing it through the vents for distribution.

When a limit switch goes bad it will cause an AC to short cycle, turning the air conditioning system off too quickly, or not turning the AC off at all.  It could be that the AC limit switch is stuck or that its wiring has short-circuited.  Whatever the case may be, it is important to contact a trained AC company in Gresham such as The Clean Air Act, Inc. for repairs.

Duct Size and Central Air Conditioning

August 13th, 2012

Having proper duct size is vital to having a Portland air conditioning system that functions appropriately.  If the air ducts are too small not enough cooled air will reach the intended rooms, if the ducts are too large the air will not have enough force to make its way from the AC to the room vents.  As such there are some AC industry standards for duct sizing which should be followed by any Portland air conditioning professional.

Air Duct Sizing for Central AC Systems

While there are many misused rules of thumb in the AC industry, there are also some newer standards which have been put into place such as “Manual D” methods of design that have already begun to improve performance of AC systems in homes and offices.

There is a difference between what is needed for an AC system supply ducts and return ducts.  Supply ducts tend to need smaller ducts while return ducts will often need to be larger.

Proper air duct sizing greatly depends on the square footage of the building being cooled, the air conditioner capacity or BTUs, how many ducts will be utilized, where they are positioned, and how many vents there are.  Additionally, the entire system will need to be properly balanced so that the AC works efficiently.

Duct sizing is based on the air volume that will be produced and the velocity at which it will be flowing through the ducts.  Determining the proper combination of these factors with the AC that will be used is essential to having a duct system that works efficiently.  A good rule of thumb for proper air flow is to have anywhere from 600 to 900 feet per minute of air flow flowing through the ducts.  To reach this, the cubic feet per minute will be determined, which will then be compared with a standard friction rate of 0.1 inches of water per 100 feet.  This calculation will result in an appropriate duct size for either rectangular or round ducts based on the size of the building and how powerful the AC is.

Air ducts should be properly sized prior to being installed.   Call The Clean Air Act, Inc. today to learn more about AC installation!
