Consider This Before Going Thermal In Your Home

Tuesday, May 29th, 2012

With energy costs rising and supplies dwindling, people are taking much more serious looks at alternatives that in the past have seemed unfeasible and too “weird” to realistically contemplate.  One type of heating and cooling appliance that is gaining popularity in Portland is geothermal heating and cooling.

Plentiful beyond imagination just ten feet below the surface, geothermal is being used to provide more than 30% of Iceland’s electrical needs and it is fast becoming a viable option to provide heat and electricity for your home as well.  Before digging straight down, however, it is important to look around and consider some important points.

Geothermal 101

Thermal energy is a force that is produced from the movement of warm temperature to cooler.  The term “geo” is from the Greek word for Earth.  Geothermal energy is the unlimited resource of power that is the result of the formation of the Earth billions of years ago (20%) and the on-going process of melting rocks nearing the core of that heat (80%).

From harnessing the energy of hot springs in ancient times to technological advances to create electricity today, geothermal has long been considered, but often was ruled out as an expensive and unnecessary alternative to other cheaper forms of energy.  Now that those are harming the environment, more expensive and harder to get, geothermal has grown attractive.

Location, Location, Location

Difficult to retrieve from deep within the Earth, geothermal is most often considered for large production where natural breaks in the crust such as volcanoes, hot springs and faults are close to the surface.  Just ten feet below the surface, however, there is enough temperature difference to make available enough to efficiently supply a home.

Still, it’s not a guarantee of success, however.  The density of the bedrock, the water table and the balance between extreme hot and cold temperatures with the temperatures of the thermal energy are all factors to be considered.

Dollar for Dollar

For new construction, geothermal is a great alternative because after the more expensive installation, the cost from month to month can produce enough savings to quickly pay for the system.  The savings are potentially so significant, there are situations where the cost of replacing an old inefficient conventional system can be neutralized by the savings in just two to ten years.

Beyond cost and feasibility, the comfort level is a major consideration.  One of geothermal energy’s major attractions is that to help save the Earth, it offers a better way to tap into the Earth.

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.

Signs of an Undersized Furnace

Friday, December 16th, 2011

If you’re purchasing a new furnace for your Sherwood home, you want to avoid buying one that is undersized for your particular space. To do that, here are some common signs that the furnace isn’t powerful enough for the heating needs of your home. These signs might appear for an older furnace as well, especially as it ages and loses its ability to provide adequate heat for your home.

Maintaining Temperature

The most common (and in many cases only) sign that your furnace is undersized is that the device simply doesn’t maintain the temperature in your home properly. This means that when turned on to full and left for a few hours, your furnace doesn’t heat your home to the thermostat setting.

This can be due to an improper load calculation or a load calculation that wasn’t taken at all. The perfectly sized furnace will heat your home evenly on the coldest day your area is likely to have. So, undersizing should be pretty evident – if it doesn’t heat your home evenly and it’s not exceptionally cold outside, you might not have enough BTUs under the hood.

How to Fix the Problem

The problem is one that varies depending on the severity of the undersizing. Modern furnaces are often available with two stages, meaning they can operate at both a low BTU rating (often around 40K or so) and a higher BTU rating (70K or higher). This is the perfect solution for homeowners worried about undersizing because it ensures that your home always has enough heat in reserve should the weather get exceptionally cold.

For example, most furnaces are sized for extremely low temperatures, but if the temperature jumps up to 50 degrees F outside, your furnace is now oversized for that weather. A two stage furnace offers solutions for both common conditions and extreme conditions and will resolve most of the concern you have about undersizing and not having enough heat to offset outdoor temperatures.

Should I get a space heater or upgrade my heating system?

Monday, November 7th, 2011

If your heating system isn’t really cutting it in your Molalla home anymore, it may be time to take a step back and consider what your options are. After all, upgrading to an entirely new heating system is a big investment and a large project that will likely disrupt your life at least for a short period of time. However, under certain circumstances it’s the best alternative out there.

One option to consider when you’re unhappy with your home heating situation is supplementing your central heating system with space heaters. These are generally inexpensive and can be placed virtually anywhere in your house or taken with you from one room to another.

Especially if there is a small part of your home that your heating system just doesn’t seem to reach or that you want to keep a bit warmer than the rest of the house, space heaters can be an excellent option. They’re small, safe and portable and can easily keep a smaller portion of your home or room cozy and warm.

However, you’ll have to take into account the operating costs of a space heater as well as the initial investment when you’re trying to evaluate the overall cost effectiveness of this option. Most space heaters run on electricity, which often costs considerably more than oil or natural gas. If your home heating system runs on electricity anyway, this might not be so much of a factor. But if you have an oil or gas furnace, you could wind up paying significantly more to run space heaters as supplemental heat over time.

Also, it’s worth considering that new home heating systems are likely much more energy efficient than the system you currently have in place. Although the initial installation cost can be pretty substantial, you’ll wind up saving a very large amount on your monthly heating bills by upgrading to a newer model.

Plus, you’ll be getting a system that should be able to satisfactorily heat your home without the need for space heaters or other supplemental heat sources. This translates into a pretty hefty savings over time and that’s something you’ll certainly have to take into consideration when you’re evaluating your options.

Plants & Indoor Air Quality

Wednesday, November 2nd, 2011

In our Molalla 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.

Help your system last longer by scheduling regular maintenance

Monday, October 3rd, 2011

While every new furnace sold comes with a limited 10 year warranty for the unit and parts, it is a good idea to supplement your warranty with a more complete maintenance agreement with your Molalla HVAC provider. Why pay for a secondary maintenance plan when you already have a warranty?

For the most part, the limited warranty provided by the manufacturer is meant to cover things like faulty parts, abnormal breakdowns or recalls. If your system simply needs to get a checkup because you use it a lot or there is a clog that isn’t caused by the actual furnace or air conditioner, you will likely end up paying the maintenance cost. So, by paying for an upgraded service plan, you cover all potential breakdowns and you’ll never again need to worry about your system. It’s like getting the upgraded warranty for a new car that covers everything from a busted crankshaft to old windshield wipers.

Help Your System Last Longer

Another benefit of a maintenance agreement for your HVAC system is that the system lasts longer when it is regularly maintained. This will ensure your HVAC system lasts significantly longer than if you were forced to wait until you could afford an extra visit from your repair man.

So, not only do you ensure your system keeps working, you add a lot of valuable years to its lifespan. Imagine how much money you’ll save if your furnace or air conditioner lasts for much longer than advertised. Any breakdowns after the 10 year mark would require hefty repairs or replacement since your warranty is expired. So, it’s in your best interest to keep your system running smoothly throughout its lifespan.

Ultimately, an HVAC system is only as good as what you put into it. If you’re careful about your investments and are willing to spend a little extra now, you’ll stand to benefit far more in the future from a smoothly operating, efficient heating system.

When to Replace Your Air Conditioning System

Monday, August 22nd, 2011

One of the last things you probably want to think about is replacing the air conditioning system in your Colton home. However, the time will come when you can no longer ignore the fact that your air conditioning system is not getting the job done like it used to. And considering your replacement options early can help save you a lot of money and aggravation in the long run.

Before you can start looking at replacement options, though, you need to be aware that the time has come to replace your current model. But how can you tell that your air conditioner is on its way out? Well, there are actually quite a few warning signs that, if you are attuned to them, will help you determine whether or not it is the right time to replace.

First of all, if you have to call for repairs, even minor ones, on a regular basis, chances are that you would be better off replacing rather than continuing to patch up the air conditioning system you already have. This is true for several reasons including the fact that a system that requires repairs so often is probably not going to last you much longer anyway.

By replacing now rather than continuing to pay for repairs, you will save a lot of money in the long run. After all, you are going have to pay for the new system sooner or later, so you might as well skip the shelling out of extra cash to repair a system you are just going to get rid of anyway.

Problems like inadequate or uneven cooling or mismanaged humidity levels in your home are a good sign that something is not working right in your air conditioning system and that it may be time to replace. At the very least, you should call someone out to take a look and let you know what type of repairs you are looking at.

You should also think about replacing an older system even if it is still working fine because the newer systems available are much more energy efficient than even the top of the line models available ten years ago. While you will have to pay the purchase and installation cost up front, you will immediately begin to save substantial amounts on your monthly cooling bills.

What Is a Whole House Pressurization Test and Should I Get One?

Monday, July 18th, 2011

If you have a forced air heating or cooling system in your home, you also have a system of ducts through which that heated or cooled air circulates. And most people don’t give a second though to those ducts. After all, if your heating and cooling systems are working, the ducts must be doing their job, right?

Unfortunately, that’s not always the case. If ducts are not working properly, the whole system will be in trouble, even when you don’t realize there is a problem. That’s why a pressurization test is so important – it provides peace of mind knowing that your home’s ductwork is not only properly installed, but that it doesn’t need any special repairs.

Why Pressure Matters

Your duct system depends on proper pressurization to evenly and efficiently distribute air throughout your home. Leaks, cracks or clogs in the system can disrupt that pressure and lead to uneven or inadequate movement of air through your ducts. This causes problems you may not notice, so if you haven’t had your ducts checked for proper pressure in a while, it’s worth looking into.

Improper pressurization causes symptoms like hot or cold spots in your home or an overall drop in the effectiveness of your home heating and cooling system. When loss of pressure is due to a leak that lets in unfiltered air from outdoors it can also lead to a decrease in indoor air quality. Often these symptoms are easy to ignore. But by doing so, you only allow the situation to get worse.

A whole house pressurization test is the best way to determine the state of your home duct system. By using high tech diagnostic equipment, home HVAC professionals check over your entire system to determine whether you have a pressurization problem. If so they can then quickly pinpoint the source. Once that’s done, the repairs are usually quite simple and you’ll get much more out of your home heating and cooling system than you did before.

Even if no symptoms of improper pressurization in your ducts have presented themselves, it’s worth having one of these tests performed. Especially if you don’t know when the system was last checked, a whole house pressurization test can help uncover small problems before they turn into bigger ones. And the peace of mind this provides is well worth the day it takes to perform the test.

How a Thermostat Works

Monday, June 13th, 2011

Your thermostat is designed to closely monitor and maintain the temperature in your home. When you flip the switch, you want your furnace or air conditioner to respond immediately. So, it’s a good idea to learn how it works so that if there is a problem, not only will you know better what needs to be fixed – you can decide whether to call a professional in for help.

Thermostats shouldn’t need input from you other than to set the initial temperature. From there, they are automatic switches. A thermometer inside the thermostat measures the indoor air temperature. When it gets above or below the limit you’ve specified, it triggers the thermostat to send a message to your home comfort system and keep things nice and comfortable.

Types of Thermostat

Thermostats come in two forms –electromechanical and electronic. An electromechanical thermostat is the simplest and has been used for decades to regulate temperature in homes. It has a simple strip or coil of metal that expands as the temperature rises and contract as it lowers. A mercury thermometer is placed on top of the strip. The coil’s movements cause the vial to tip as the temperature changes. There is a pair of electrical contacts on either end of the vial. The mercury can absorb that electrical current when the electrical contacts touch the thermometer. The mercury then acts as a switch to turn on your comfort system.

An electronic thermostat simply has an electronic sensor that measures the indoor air temperature. You set a temperature for your room and when it changes significantly, the switch inside your electronic thermostat is triggered, causing it to turn on your comfort system.

Ways to Upgrade Your Thermostat

Most homes only need the bare minimum in their thermostats. However, there is some very exciting technology on the market these days that can add quite a bit of value to your system. Not only can you install a programmable thermostat, you can opt for zone control systems that allow multiple thermostats in different rooms of your home.

Programming allows you to set temperatures for certain times of the day. This is especially great if you are gone from the house for long periods of time each day. Why heat or cool a home when it is empty? And if you have multiple people with different temperature needs, zone control temperature control allows you to set specific temperatures for specific rooms in your home – a very enticing option for large families or multi-story homes.
