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.

Where Are Air Cleaners Installed and How Do They Work?

Monday, 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.

Oregon City Home Air Filtration Installation Experts

Your family deserves to breathe clean air. For people suffering from existing respiratory problems, air filtration can be a necessity. Whole home filtration systems can reduce allergy flare-ups that result from pollen, dust and other pollutants like pet dander. Many homes in the Oregon City area are well-insulated which can leave little room for ventilation of normal allergens. Clean Air Act, Inc. has a full range of products that can remove pollutants from your air and ensure that you and your family are comfortable all year long.

When to Replace Parts of Your Geothermal System

Tuesday, 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!
