Heat Pump Refrigeration Problems

Wednesday, March 7th, 2012

Heat pumps in Damascus are very complicated pieces of equipment that use a number of moving parts to compress and circulate refrigerant, and extract heat from one environment and place it in another. So, if your heat pump has refrigeration problems, it will almost certainly cause problems for the heating or cooling of your home.

Common Refrigeration Problems

There are a number of potential problems your heat pump might face, especially as it begins to age and components become worn. Some common issues include:

  • Compressor Issues – The compressor is a component in your heat pump that compresses the refrigerant gas into a liquid. This liquid is what circulates through the device and extracts heat from the outside air (or inside your home when in cooling mode). If the heat pump doesn’t turn on properly, isn’t producing enough heat or is using a large amount of electricity suddenly, it may be a compressor problem.
  • Refrigerant Leaks – Your heat pump doesn’t consume any refrigerant during operation. So, if it starts to leak refrigerant, there is likely another problem your heat pump needs to be repaired immediately (for health and environmental reasons). Common signs of a leak include suddenly higher electrical bills, inefficient heating and possibly even a faint odor near the device.
  • Freezing Up – If your heat pump freezes, you should check for any blocked air vents or registers, check the condensate line and check your filter for blockage. Most often, a freezing problem is directly related to something being clogged and is a relatively easy fix. The only way to know for sure is to call a professional to investigate, however.

A heat pump is a very complex piece of machinery with a number of moving parts that can all cause issues if not properly maintained. If your heat pump stops heating or cooling effectively and it is not a simple fix such as a filter or belt, you should call Clean Air Act to inspect for more significant problems such as the compressor or refrigerant.

What Does an Air Handler Do?

Wednesday, February 8th, 2012

A Portland resident’s HVAC system is a complex system filled with vital components tasked with keeping you comfortable. One of the most important of those component is the air handler – the device responsible for circulating the heated or cooled air produced by your system through the vents in your home and into each of your rooms.

The air handler is a metal box, usually consisting of a blower and the heating or cooling elements. It might also include dampers and sound attenuators along with an air filtration and humidity control system. The simplest air handlers are designed only to transfer the heated or cooled air to the various parts of your home, while the most advanced devices are designed to perfectly condition and clean that air as it is circulated.

Types of Air Handler

There are a few different types of air handler as well, depending on the size of the HVAC system and the nature of the heating and/or cooling used. Most homes, for example, use terminal units which consist of just an air filter, blower and coil. This very simple system is all you really need to heat and transmit air through your ductwork.

However, for larger systems, there are also makeup air units which use outdoor air instead of recirculated indoor air. There are also packaged and rooftop units which are designed to be placed outside. These devices are most commonly used for commercial applications when space is limited.

How the Air Handler Works

An air handler’s most basic component is a blower fan. This device is run by an AC electric motor and can be either single speed or variable speed depending on the size and scope of your air handler. The dampers on the fan will control the flow rate of the air going through the blower fan. Most residential blowers are part of the air conditioning or furnace system, while commercial systems often have multiple blowers to maintain steady airflow for a larger space.

Because an air handler passes all of the air that will go through your vents, it is the best place to install high quality MERV or HEPA filters to remove pathogens and contaminants. It is also a good place to install humidity control devices to either raise or lower humidity depending on the time of the year.

Your air handler is an incredibly important component in your home heating and cooling system. Without it, all that heated and cooled air you pay for each year wouldn’t reach you. So, make sure to keep your system in tip top condition.  If you have any questions about your heating and cooling systems please contact Clean Air Act Heating and AC experts

A Brief History of Geothermal Energy

Wednesday, January 25th, 2012

Geothermal energy is nothing new – it just gets more ink because of its increasing use to naturally heat and cool buildings in Gladstone, leaving a smaller carbon footprint and providing for an efficient, more cost-saving method to achieve indoor comfort.

History shows that geothermal energy dates back over 10,000 years when American-Paleo Indians used hot springs for bathing and heating, possibly even as a source for healing. And geothermal energy is not just a North American idea either. The oldest known hot springs spa was built in the Qin dynasty in China in the 3rd century B.C.

Romans used the water from hot springs for their public baths. Geothermal water was also used by the Romans for treating skin and eye diseases. Minerals found in hot springs water has been long believed to have healing qualities. Geothermal water was also used to heat the buildings in Pompeii. Subsequently, building heat was obtained from under floor systems.

History notes that France is home to the world’s oldest known geothermal district heating system. The system in Chaudes-Aigues has been in use since about the 14th century. And starting in 1960, France began using geothermal heating for homes in other areas. Up to 200,000 homes in France are heated by geothermal means.

History also shows geothermal energy use during the late 18th century near Pisa, Italy. Geothermal energy had been used to extract boric acid from the Larderello Fields through the use of steam. In 1904 at Lardello Fields, steam was successfully used to generate power for the first time. At the time, geothermal energy was seen as the power of the future.

In the U.S. in 1892, the first district heating system in Boise, Idaho was powered directly by geothermal energy, and was soon copied in Klamath Falls, Oregon in 1900, where geothermal water was pumped under sidewalks and roads to help prevent freezing and ice build up. In New Mexico rows of pipe were placed underground to keep soil warmer for agricultural purposes.

A deep geothermal well was used to heat greenhouses in Boise in 1926.

For the residential market, an inventor built a “downhole heat exchanger” in 1930 to heat his house. The heat pump, which was invented in 1852, was patented to draw heat from the ground in 1912. However, it was not until the 1940s that the geothermal heat pump was successfully launched. Records show that the first commercial heat pump was put into use in Portland, Oregon in 1946. The first residential open loop system was installed in 1948.

In the 1960’s, the first large scale industrial geothermal energy power plant was constructed, producing 11 megawatts of geothermal electricity. From the 1960’s to the present day organizations and governing bodies have been set up to manage, research, and develop new and improved geothermal energy sites and technologies.

Today, there are many geothermal power plants in working order in the U.S. and across the globe.

Why AFUE Ratings Matter For Your Heating Installation

Wednesday, January 18th, 2012

When you are in the market for a new furnace for your Newberg home, there are several reasons you should pay attention to the annual fuel utilization efficiency (AFUE) rating. All newer model furnaces get an AFUE percentage, which measures how much fuel a particular model converts into heat. Furnaces with higher AFUE ratings are more efficient, but the size and type of furnace will also factor into how much you’ll save on energy costs.

Understanding the AFUE Ratio

The minimum AFUE rating for new furnaces is 78%. This means that seventy-eight percent of the fuel is turned into heat, and the remaining percentage is lost either through poor insulation, air leaks, or the ventilation system in the home. Because there’s no heat loss through a chimney flue, some all-electric furnaces can have an AFUE rating as high as 98%. However, if the cost of electricity used to meet your normal heating needs is higher than the efficiency savings, you may want to consider other options. Talk to a qualified HVAC contractor for advice about the most cost-efficient heater for your home.

Furnace Efficiency Features

Furnaces manufactured 15-20 years ago have significantly lower AFUE ratings (between 55%-70% for most older models) because they are typically single-stage, or single-speed systems. Single-stage furnaces are less efficient because they are designed to cycle on at full capacity and shut off when the desired temperature is met.  Newer, two-speed models have a second setting that runs consistently at a lower speed, which saves energy by burning less fuel. Multispeed furnaces that have variable-speed blowers are the most efficient because they operate at various levels and automatically adjust to the thermostat to maintain a constant temperature.

If you look at the AFUE ratings for multispeed and variable-speed furnaces, the ratios should be above 80%. Keep in mind that this only determines the efficiency levels for the furnace itself. You’ll need to factor in whether or not your home has proper insulation and other upgrades, such as double-paned windows and doors.

Troubleshooting Your Problematic Heat Pump

Friday, January 6th, 2012

If your Gladstone home’s heat pump isn’t working properly, there are a number of things that might be wrong. But, where do you start and how do you solve these problems quickly and inexpensively? Here are some tips for common heat pump problems.

Low Air Flow

Your heat pump is designed to provide steady air flow to the entire house. When it was originally installed, the technician sized it to do so. If it suddenly stops providing enough air flow to your entire house or if the air flow it provides isn’t as comfortable as you’re used to, something is probably wrong.

More specifically, there is likely an issue with the heat pump itself since the device will compensate for most external problems by running longer and harder. A quick inspection will often rule out serious problems, so you should have someone inspect your device as soon as you notice a problem.

Leaky Duct

If there is an external problem, such as leaky ductwork, it tends not to be as noticeable right away. Often, when ducts are leaking, air flow problems will occur only in certain rooms of your home. Even then, the heat pump might be able to maintain the right temperature in those rooms – you’ll just have a higher energy bill because of the energy loss in the ductwork.

The best way to determine what is happening and how best to tackle the problem is to have someone test your ductwork for leaks, a relatively quick process.

High Energy Bill

If your energy bill suddenly increases dramatically, it is usually due to energy loss somewhere in the transfer between the heat pump and the rooms of your home. Leaky ducts can be the culprit, but so too can the air handler or the heat pump itself. If you notice a sudden increase in your energy bill, look for other symptoms like uneven heating or cooling in certain parts of your home or noises coming from the ductwork or your air handler.

No matter what other symptoms accompany the increase, you probably need repairs. Your home may still be comfortable now, but the heat pump can only make up for the problem for so long and in the interim, it is being put under excessive stress that reduces its lifespan.

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.

The Effect of Dust Mites on Indoor Air Quality

Wednesday, September 21st, 2011

There are three types of indoor air pollutants in your Oregon City home  – particles, bioaerosols and gases. Dust mites are a special case because they are nearly invisible to the eye, but represent a substantial bioaerosol that can make it harder to breathe and result in a number of sometimes debilitating symptoms.

What Are Dust Mites?

Dust mites are tiny arachnids related to ticks and spiders that cling to fabric like curtains, carpet and upholstery. They resemble dust in the air and thrive in high humidity conditions. So, the easiest way to treat a dust mite problem is with proper dehumidification. Knowing whether dust mites are a real problem if you simply have a lot of dust and pollen floating around is tough. Here are some common symptoms to look for:

  • Dizziness
  • Nose Irritation
  • Respiratory Irritation
  • Cough
  • Chest Tightness
  • Asthma (made worse)
  • Allergic Reactions

Because dust mites are alive when you breathe them in, they can cause severe irritation to your throat and lungs and result in a number of uncomfortable reactions – ranging from a runny nose to a full blown allergic reaction.

Getting Rid of Dust Mites

So, how do you get rid of these tiny arachnids? The first step is to improve the humidity level in your home. Anything under 50% humidity makes it impossible for dust mites to survive, so air conditioning in the summer and dehumidification in the spring and fall are the best steps to remove the threat of these little bugs.

Tiny dust mites are among the larger air pollutants and can be captured by most MERV 10+ filters on the market. A HEPA filter will absolutely remove them as well, along with any other particulate or bioaerosols in your home. You might also consider an air cleaner.

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

Wednesday, July 13th, 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.

Keeping Your Home Toxic Chemical Free

Monday, July 4th, 2011

So, you have decided you want to try to go chemical free in your home. Whether you want to be friendlier to the environment at large or just foster a healthier home environment for yourself or your kids, eliminating toxic chemicals is a big step. Below are some tips to help you go about it the right way.

Removing Toxins

The first step is to eliminate some of the major toxic chemicals that may already be in your home. First, make sure your home’s ventilation system is functioning properly. Clean vents regularly and inspect the system and change the filter annually.

Consider using a water purification system to remove chemicals like chlorine — which is used to kill microbes in many water systems — as well as drug residues and heavy metals. Remember as well that lead is a dangerous toxin, so have your home inspected for it. Remove and replace any paint, pipes, or other materials made of lead. This is especially important if your home was built prior to 1978.

Finally, have your home checked for radon and asbestos. These are both harmful toxins that can easily be breathed in without being noticed. Check for radon especially if your home has a finished basement, or if your family spends a significant amount of time in the basement.

Keeping them Out

Now that you have expelled these contaminants from your home, look for ways to avoid inviting other potentially dangerous chemicals in. Most of us use toxic chemicals every day without even realizing. To help keep these toxins out of your home, you should look for cleaning supplies that are chemical-free. Companies that manufacture and distribute chemical-free cleaning products include Method, Seventh Generation and Ecover.

You can take it a step further by using DIY cleansers. Baking soda, lemon juice, vinegar and salt are all useful in household cleaning and are much safer for children and pets than chemical-based products. Drain clearing products contain extremely harsh chemicals that can contaminate water supplies and even damage your plumbing. A combination of baking soda, vinegar and boiling water can be just as effective without the toxicity.

Finally, use soap as an alternative to chemical air fresheners. Simply leave a few bars around the house in strategic locations. The soap will absorb nearby odors. For added effect, use scented soap.

Start with these simple steps and you will be off to a good start in keeping harmful chemicals out of your home and away from your family.
