How Your HVAC System Uses Electricity

Monday, June 18th, 2012

While not every HVAC system in your Portland home requires electricity, many of them do. Your air conditioner, electric furnace or water heater and ventilation system all need access to the central power line. So what does that mean for your system and what problems should be you beware of?

How Your HVAC System Uses Electricity

How your HVAC system works depends largely on which components need electricity to operate. Here is a quick summary of how each system uses electricity:

  • Air Conditioning – Most air conditioners are electric and therefore use electricity based on the number of BTUs produced. For example, if your air conditioner produces 25,000 BTUs and has a SEER of 16, it can produce 16 BTUs for every watt of electricity consumed per hour. As a result, it consumes 1,562.5 watts per hour when the system is running at maximum capacity. If it runs at full capacity for 8 hours per day, 30 days a month in the summer, that’s 375 kilowatt hours – which is the measurement unit you’ll see on your electric bill.
  • Heating – Your heating system may not use electricity, as many homes today use gas or oil combustion furnaces or boilers to produce heat. However, if you have an electric furnace, that electric power is used to heat the filament in the furnace. Electricity also powers the blower fan motor which pushes air across the filament and into the air handler. An electric furnace sized to heat a 1500 square foot home can use up to 8,000 watts per hour to produce enough heat for your home. That converts to roughly 5,000 kilowatt hours per month. The current price of electricity will determine how much this actually costs, you but it can really add up quickly.
  • Ventilation – Your ventilation system is almost always going to use electricity to circulate and filter air. While mechanical filters rely on the movement of air to remove certain particles, ventilation systems have a variety of components including fans and possibly even condenser coils to conserve energy as air is exchanged between the inside and outside.

Electricity plays an important role in your Portland HVAC system no matter how your system works. To ensure yours continues to operate as intended, have your power system checked on a regular basis when the rest of your HVAC system is serviced.

Can I Use Geothermal Heat if I Live in a Cold Climate?

Monday, June 4th, 2012

Geothermal heat pumps in Beavercreek are able to extract heat from the ground, even when outdoor temperatures are well below freezing. They use a system of pipes installed in the ground below or around your home to collect this heat and then return it to your home where it can then be used to heat the air. While these types of heating systems are certainly more efficient the warmer the ground is, they can be effective even in very cold climates.

This is true even in areas where the ground freezes from time to time or for parts of the year because the frozen layer does not typically extend more than three or four feet below the surface. As long as the pipes for your geothermal heating system are below this level, they will still be able to gather plenty of heat from the warmer ground below the frozen layer.

In fact, there are two different ways that the pipe loop for a geothermal heating system can be installed. Most geothermal systems have a horizontal pipe system which sits about four feet below the surface and extends out from the house. This type of installation is typically cheaper than the alternative, but it also usually needs to be larger. Plus, you need to have the space for it to stretch across.

On the other hand, a vertical installation goes straight down into the ground below your home. With a vertical installation, you can usually get away with less pipe overall, but you will probably pay more for the installation because it is harder to drill straight down than it is to dig out a relatively shallow trench to lay the pipe in.

However, if you live in an area that has particularly harsh winters when the ground can be frozen for significant periods of time, it may be worth it to opt for the vertical installation. That is because the further below the surface the pipes go, the farther away they will be from the frozen layer of ground.

With a vertical pipe installation, a geothermal heating system can work quite well in a climate in which the ground usually freezes in the winter. While you will always want to have a backup heating system in place in case of emergencies, this type of heat pump should be all you need under normal conditions.  Please give The Clean Air Act a call if you have anymore questions about geothermal heating and cooling.

How Animal Dander Affects Indoor Air Quality

Monday, May 7th, 2012

One of the single most common indoor air quality pollutants in Gladstone is animal dander. The flakes of dead skin, fur or feathers produced by pets and outdoor creatures can be an allergy nightmare for millions of people. Even those without allergies tend to be less comfortable in spaces that have animal dander issues. Here are some things you should know about animal dander and allergies.

What’s the Issue?

Dead skin from dogs and cats is the biggest problem, with 27% of US homes having cats and 32% having dogs. Cats are a much larger allergen producer however. The number of allergy related complaints among cat owners is twice as high as that of dog owners according to the American Lung Association. Male cats are slightly worse than female cats as well. Don’t forget either that fur is not the primary source of dander. Dead skin, dried saliva and even specs of dried feces can contribute to indoor air quality issues. So, short haired cats or dogs are not any better for your home.

Another thing to consider is that pet dander is suspended in the air much longer than any other allergen because of how light it is. We’re talking about days of suspension, after which it settles into carpets, furniture, clothing and anything else with enough surface area to attract the dander.

Health Problems from Dander

For those allergic to animals, pet dander is an instant irritant. Just walking into a home in which a cat or dog is present can have an instant negative effect – including anything from coughing and wheezing to a runny nose or chest constriction.

Unfortunately, the easiest way to remove pet dander is to remove the pet and for severely allergic people, this is usually the only option. For others, however, there are some things you can do. You can remove the allergens themselves with high powered indoor air cleaning or filtration. You can also set aside areas in the house that the pet is not allowed into and take steps to make sure pet dander doesn’t get into the air supply for that room.  For more information about indoor air quality solutions please call The Clean Air Act

Improving Indoor Air Quality with UV Germicidal Lights?

Monday, April 30th, 2012

To improve the indoor air quality use ultraviolet germicidal lights in Portland homes to kill harmful bacteria, viruses, and toxic mold that can cause respiratory problems and other health concerns. These microorganisms spread by releasing airborne spores containing the genetic material used to create a new organism. UV lights use a wavelength of ultraviolet light to destroy the organism’s DNA, which takes away their reproductive capabilities and also kills them.

UV germicidal lights are fairly inexpensive and can be installed to work with your existing forced air HVAC system. They are typically used in tandem with either an electronic or mechanical air cleaner. While air cleaners can filter pollen and other irritants, UV germicidal lights destroy the viruses and mold spores once these pollutants have been trapped by the air cleaner. After the air has been filtered through your HVAC, it will circulate more easily through system and increase the efficiency of the unit. In addition, UV lights are useful in killing hidden mold growth, which can only be detected by special thermal imaging equipment.

Homeowners with particularly chronic allergy problems or extremely poor indoor air quality choose to install both types of air cleaners, in addition to a UV light, for the ultimate protection from indoor air pollutants—from bacteria to pet dander.  If your home lacks adequate ventilation, or if you are unable to control the source of common pollutants, you might benefit greatly by installing UV germicidal lights. Poor indoor air circulation can exacerbate the spread of harmful microorganisms, so make sure you have proper ventilation if you don’t have UV lights in your home.

UV germicidal lights have also been used to filter tap water because they are more reliable and easier to install than other water treatment systems. However, they are typically used to provide cleaner indoor air quality.

Call Clean Air Act if you have questions or concerns about the quality of the air inside your Portland home.

How Do I Get More Fresh Air in the House During the Winter?

Monday, April 16th, 2012

Winter is a real bummer for many Welches families. It’s cold and dark outside and to top things off, you have to keep your home sealed up nice and tight so the warm air produced by your boiler or furnace doesn’t escape. Not a lot of fun. Luckily, there are solutions to help your indoor air quality in Welches. Which solution you choose will depend on a few factors, however.

The Simplest Way

The easiest way to get fresh air is to open a window. Unfortunately, it is also the most expensive way. After all, the air outside is cold and by opening a window, you force all the air you just heated outside. Most modern heating systems can compensate for the energy loss, but it will cost you quite a bit over the course of the winter to heat not only your home, but your backyard.

That’s why there is so little circulation in the winter to start with. The need for effective insulation and weather stripping to reduce energy use and fuel costs led to increasingly sealed up homes.

Ventilation

So, ventilation is the next best option, and while there are fans and exhaust options that allow you to circulate air into and out of your home, the most cost efficient way to do so is with a heat recovery ventilator or for those with humidity problems, an energy recovery ventilator.

These devices contain advanced heat exchangers that will transfer the heat from your indoor air into new air as it is brought into your home. As fresh air is transferred inside, the heat is passed from indoor air to the outdoor air via a heat exchanger. By retaining the heat with a recovery ventilator, you keep your energy bills low and your home filled with fresh air.

The best part is that this same technology works in the summer if you want to let in a little fresh air on a sunny day. Instead of pouring all of that cool air conditioned air outside, you can simply use an energy recovery ventilator to draw heat out of new air as it enters your home. Heat and humidity stay outside and you stay nice and cool.

There are quite a few types of energy recovery ventilators, ranging from simple heat only models to advanced heat pumps that will gather lost heat from throughout your home. The size of your home and the climate in which you live will determine which the best fit is for you.  If you have questions call Clean Air Act

Heat Pump Maintenance

Monday, December 12th, 2011

Heating and cooling your Cornelius home is a priority. You need your home and family to be comfortable all year round, so you either got or are considering a heat pump. These machines are great because under the right circumstances, they are essentially all-inclusive and incredibly efficient solutions for all your home heating and cooling needs.

Notice the “under the right circumstances” part. A number of things have to be considered when choosing a heat pump, such as the climate and the size of your home. But these are not the only circumstances that influence how well your heat pump works for you. Proper maintenance is a vital component of heat pump ownership, ensuring that you get the best performance out of your heat pump for the longest time possible.

A major part of properly maintaining any machine is to keep it clean. A heat pump is no exception. Dirt and dust can affect the efficiency of your heat pump, as well as speed up corrosion problems. Keep the compressor and coils clean. Check them monthly or so and remove any accumulated dirt. Also, consistently check and change filters according to the manufacturer’s recommendations.

Simple cleaning is an easy and effective first step to heat pump maintenance, but there are some things that you just won’t be able to do on your own. For more intensive maintenance, it is best to call in a professional for an annual inspection.

During a routine maintenance check of your heat pump, a technician will inspect the whole heat pump system for problems. He will clean the compressor and coils, tighten any connections that may have loosened up and change the filters as needed. In addition, a skilled technician will be able to detect any early signs of trouble and make necessary repairs to prevent break downs. These small repairs can prevent big problems later on, thereby preventing some serious discomfort and a possible big expense.

If you are considering a heat pump as a heating and cooling solution for your home, great. If you have already decided on one and had it installed, congratulations on making a smart decision. Now, make another smart decision to protect that investment by keeping your new heat pump properly maintained.

How to Calibrate Your Thermostat

Friday, December 2nd, 2011

Have you ever set the thermostat in your Cornelius home to a desired temperature and “hoped for the best?” Maybe it’s because the temperature setting you expected this finely tuned instrument to maintain just isn’t right. You may see 70 degrees on the thermostat but the home feels more like 65 degrees. In fact, if you used a hand-held thermostat, you might get real proof that your thermostat is not working like it should.

There are reasons for a malfunctioning thermostat and solutions to correct them, namely calibration. First, let’s look at some reasons why a thermostat can be out of kilter.

The first thing to note is that thermostats are very sensitive instruments and change to the slightest changes in temperature. An incorrectly installed thermostat or one that is accidentally bumped or jarred can malfunction. It may wind up out of level, causing it to operate incorrectly. Possibly the most common problem affecting accuracy is a build-up of dirt, which can affect the calibration of the thermostat. Other problems may be caused by loose wiring.

Here are some steps you can take to check your thermostat for accuracy and recommended actions.

  1. Use a standard glass thermometer to check the room temperature. You should mount it on the wall nearby your thermostat and use some padding to keep it from actually coming in contact with the wall, which could affect the readings.
  2. Wait 15-30 minutes for the thermometer to adjust to the temperature and enable it to give the most accurate reading. Once the time has elapsed, compare its temperature reading to that on your thermostat.
  3. If there is more than a one degree variation, your thermostat may be dirty. Remove its faceplate and examine it. If there is dirt or dust inside, blow it out. If you can reach the contact points, you can clean them with a new dollar bill (and speaking of dollars, a clean and accurate thermostat will make your furnace run more efficiently and save you money on your utility bill).
  4. Some thermostats use a mercury vial which can indicate if the thermostat is level or not. If it is not level, a simple adjustment using a screwdriver may do the trick. In the worst case, you may have to remove the thermostat and drill a new hole to reinstall the mounting screw in a different location.
  5. Now that you have made these corrections, check both thermostats to see if the temperatures match. If they don’t, try steps 3 and 4 again. If that still doesn’t work, your problem may be more than just a dirty, lopsided thermostat. You may need to replace the thermostat – or even look at the heating system in its entirety. It could be time to call a professional heating contractor to check out your entire system.

Today’s thermostats have few working components but are very sensitive, advanced instruments. It takes little to throw off a thermostat but luckily, it takes little effort to correct the resulting problems.

HVAC Maintenance the Whole Family Should Know

Monday, November 14th, 2011

If you think the most important thing a heating and cooling (HVAC) system can do is to provide an comfortable environment in your Cornelius home, you are right. But there is another thing an HVAC system does that is very important and it affects your entire family. It provides a safe indoor environment, too.

Besides warmth in the winter, a finely-tuned HVAC system can clean and filter the air you breathe. That’s important to people who suffer from allergies and is especially important for minimizing the spread of germs that cause colds and the flu. The key phrase in this paragraph is finely-tuned. If your HVAC system is not working correctly – out of tune – it can cost you a great deal in monthly utility bills and can be harmful to your health.

It is important for you and your family members to understand the basics of HVAC system maintenance so you can all understand the symptoms of improper maintenance and its consequences. For example, if anyone in your home is suffering from flu-like symptoms or are constantly drowsy or listless, they may be suffering from the a silent killer: poisonous carbon monoxide gas. This gas is formed during incomplete combustion of fossil oils like natural or propane gas. A malfunctioning furnace can emit carbon monoxide gases and you may never even realize it, until it is too late. Long-term exposure to the gas can cause brain damage and/or chronic sleepiness. It some cases, it can even cause death.

You may be able to diagnose the problem, but you aren’t qualified to test and repair a furnace that is creating deadly carbon monoxide gas. Your best bet is to call a qualified HVAC contractor who can diagnose the furnace and offer repair or replacement suggestions. But there are things you can do to prevent the build-up of carbon monoxide gas.

Check all exhaust vents, like chimneys and flues for any blockages. A blocked or partially blocked vent can cause the build-up of carbon monoxide gas. And never, EVER, use a gas or propane powered heater in an unvented area of your home. These types of heaters create various levels of carbon monoxide gas that needs to be circulated out of each room and replaced with clean, fresh air. So, your family can actively ensure that there is no debris, bird’s nests, animals, leaves, or snow in the ventilation system.

You can also “help” your HVAC system by keeping vents clean by vacuuming dirty vent grilles and, in general, keeping the home clean. The cleaner the home, the easier it is for your furnace to do its job and the easier it will be for you and your family will breathe. These are a few easy maintenance tips will keep you and your family warm – and safe – this fall and winter.

Did You Change that Furnace Filter?

Friday, October 21st, 2011

No matter what type of furnace you have in your Cornelius home, it’s important to remember to change or clean the filter on a regular basis. This is a relatively straightforward process and doesn’t require any professional help. However, if you’re not sure how to go about doing it, you can always have your heating technician demonstrate the process for you on their next regular maintenance visit.

Indeed, changing or cleaning out the furnace filter is an important part of regular furnace maintenance. However, it often needs to be done more than once a year. The specific amount of time that you can go between filter changes depends on many things, but typically it’s good to check on it once every three months or so.

If you have a lot of pets or if anyone in your family has severe allergies, it may be worth it to check and change the filter even more often. Check with the manufacturer to see what their recommendations are as well. Some high performance furnace filters can last up to six months or even a year, but you should still check on the filter periodically to make sure that too much hasn’t built up on it in between replacements or cleanings.

You’ll need to make sure you have the right type of filter to install as a replacement as well. You can get this information from the owner’s manual of your furnace, from the manufacturer or by taking out and examining the current filter in your furnace. Some furnaces also have filters that are meant to be cleaned and then put back in and the cleaning instructions are usually located near the filter itself.

Of course, in order to change your filter you’ll first have to be able to find it. Most of the time, the filter will be located near the blower towards the bottom of the furnace. However, if you’re not having much luck finding it, your owner’s manual should be able to tell you quickly where it is and how to remove it. Before you go to open the chamber and take the filter out, however, be sure you’ve turned off the power to the furnace.

Changing your furnace filter can help improve the air quality in your home and it is also very important when it comes to keeping your furnace running efficiently and effectively. The filters are there to trap airborne particles that can get into the blower and clog it up. When that happens, the performance of your furnace will likely drop and you’ll need to have a professional come out and complete the necessary repairs.

Furnaces vs. Heat Pumps

Monday, October 10th, 2011

If you’re preparing to replace your existing heating system in Cornelius, you may very well be struggling with the question of whether to go with a furnace or a heat pump for all of your future home heating needs. Each of these systems have their own advantages and drawbacks, and once you’ve narrowed it down to one type or the other, you’ll still have a pretty wide variety of products to choose from.

Furnaces are still the most popular type of home heating equipment on the market. You can get furnaces that run on gas, oil or electricity, although gas furnaces are by far the most common type of furnace around these days. The latest models are extremely energy efficient, with AFUE ratings reaching into the high 90%s.

Like heat pumps, furnaces use ducts to transfer heated air throughout your home. They typically require regular maintenance once every year or two depending on the type of furnace you have, and they can be expected to last anywhere from 15 to 25 years when properly maintained. Most modern furnaces are also made to be compatible with a central air conditioning or cooling system as well.

Heat pumps, on the other hand, don’t generate the heat that they circulate throughout your house. Instead they are able to extract the heat from the air outside and pump it inside. This means that they use much less energy than even the most energy efficient furnaces.

However, heat pumps are only capable of heating your house comfortably when the outside temperature is above freezing. If you live in an area with particularly long and frigid winters, you’ll probably find that you need to supplement your heat pump with another heat source. Because of this, it actually makes little sense to use a heat pump in more extreme climates.

On the other hand, if you live in an area with relatively mild winters, heat pumps can be a great option. They provide a constant flow of warm air to all parts of your home and can also keep you house cool during hot summer months. To cool your home, heat pumps simply reverse the process they use to warm it. They take the heat out of your indoor air and pump it outside. This is a very effective home cooling method and makes heat pumps a great solution for year round comfort.
