Geothermal Heating In The News

A geothermal heating system still needs some electricity to run its pump and air circulating fan, but it uses much less than traditional heating and cooling systems which keeps the cost of running one very low. However, getting a geothermal system for a house also involves a more complex installation process.

Geothermal heating and cooling systems are gaining popularity because they use very little energy to keep a home at a steady, comfortable temperature. Geothermal technology transfers heat between your home and the earth’s crust where heat is a naturally renewing resource.

We know from experience that on the earth’s surface the temperature varies, making us cold in the winter and hot in the summer. However, the temperature only six to ten feet below the surface maintains a relatively constant temperature of about 50-60 degrees Fahrenheit.

Geothermal technology takes advantage of the steady underground temperature and the fact that heat naturally flows out of hotter areas into colder areas.

It works by circulating a refrigerant fluid through pipes that run from inside your home to below the earth’s surface. On hot days, the fluid will absorb heat from the air in your home and transfer it down to where the cooler ground will absorb it. On cold days the fluid brings the heat from below the surface up to where it releases into your home. A compressor in the system intensifies the temperature change of the fluid so that it can warm or cool a home quickly.

Installing a geothermal system still comes with a large price tag right now, but it may become more affordable and practical in the near future as we look for cleaner ways to heat and cool buildings.

Despite an uncertain economy, geothermal heat pump adoption is increasing in the United States. Over 1,000,000 geothermal (or ground-source) heat pumps are used in U.S. residential, commercial and government buildings. And each year, U.S. homeowners install approximately 50,000 more geothermal heat pumps. American homeowners are clearly warming up to the fact that green geothermal energy is available anywhere in the United States - literally in their own back yard, thanks to ground water heat pumps.

The big news: compared with other sources of energy, geothermal energy is only beginning to reach its potential - even though the history of geothermal energy in the U.S. dates back more than 10,000 years and first geothermal ground-source heat pump was installed in 1945.

Cool Arizona Places: Hiking in the Lost Dutchman State Park

Thinking of a spring hike in the Superstition Mountains in Lost Dutchman State Park. They are beautiful, majestic, and just lurch out of the desert floor. They are unbelievably overwhelming in contrast to the vast emptiness of the desert.



The awesome hiking trails around the base of the mountain offer beautiful views, and for first-timers try the #56 trail loop (Treasure Loop Trail, 2.4 miles) because it gives you excellent viewpoints and is easy enough that you can be up and back in about an hour and a half, give or take. If you’d like to hike longer, you can extend your hike by taking the #57 trail (Prospector’s View Trail, 0.7 mile) over to the #53 trail (Siphon Draw Trail, 1.6 miles to Flatiron).

Gold in the Superstitions

There are so many legends surrounding these mountains. Until the mid-1800s, most of the legends revolved around the Apache Indians.

In the 1800s a German prospector named Jacob Waltz emerged from the hills with gold ore. Apparently, he didn’t tell a single person until his deathbed. Before he died in 1891 he left clues to the location of the Lost Dutchman Mine. There was even a movie that depicted the gold, and that led to a fever rush of gold prospectors. Jacob revealed the clues on his deathbed, and even revealed for the first time.

At the age of 45, Jacob Waltz immigrated from Germany to the United States, and later became a citizen of the United States (in California). In 1863 he left California, and headed to Arizona. He became known as “The Dutchman” and claimed a homestead near the Salt River. At this time, the Apache Indians were still active in the area, including the Superstition Mountains.

There have been over a 100 documented deaths in the Superstition Mountains. Some of them have been shot and killed, over a piece of dirt that they thought was the location of the mine, but later turned out to be nothing. It may be a fools promise of hidden riches. There’s something about those mountains that is very rough, and very intriguing, but you can’t go into them thinking you’ll become very rich, because you most likely won’t.

When he died, he had 24 pounds of very rich gold ore hidden under his bed.

There are so many stories related to the lost gold, and to get started read about the gold mine, and the Peralta stones (rocks left by the Peralto family in the 1800s to help them find the gold).

If you’re curious about looking for the gold while you’re hiking, you’ll want to consult the list of clues that are based on research people have conducted. 

Cactus and Plants

On your hike you’ll see lots of saguaro’s, ocotillo, cholla, and a variety of other cactus. There’s a lot of Palo Verde trees and Mesquite bushes.

At Aaron’s Mechanical Services we want you to stay comfortable all year round.  If your HVAC unit needs service or replacement please think of us and call at 623-388-4436 and we will come to you and solve your air conditioning service needs.

Aaron’s Mechanical Services: Phoenix Weather Is Unpredictable

Just a few days ago we saw eighty degree temperatures here in the Valley of the Sun and now in March we start out with two days in the fifties and sixties. Just seems like when we think we are warming up and getting ready to think air conditioning we find we need our heating systems and warm jackets.

That sure isn’t news for the folks at the National Weather Service. It is their job to predict our local weather. Something that isn’t easy to do.

The outlook for the Phoenix Metro Area for March is cooler (3 degrees) and just a bit wetter than average.  At the end of March we will see how accurate that is.

If we take a snapshot of a weather forecast here is what we see;

AT 8 PM MST THE COLD FRONT HAD SHIFTED INTO EASTERN ARIZONA ALONG
WITH THE PRECIP BAND. IN THE WAKE OF THE COLD FRONT THIS EVENING A
FEW SHOWERS CONTINUED OVER PORTIONS OF SOUTHEAST CA...SOUTHWEST AND SOUTH CENTRAL AZ. THIS EVENINGS UPPER AIR DATA CONTINUED TO SHOW LOW LEVEL SOUTHWEST WINDS STILL ENTRAINING BOUNDARY LAYER MOISTURE INTO SOUTHWEST AND SOUTH CENTRAL AZ FROM THE BAJA REGION. THIS MOISTURE COMBINED WITH A BROAD UPPER TROF THROUGH TUESDAY WILL CONTINUE A MARGINAL THREAT OF SHOWERS. CLEARING WEDNESDAY.

I’m not sure that the National Weather Service does a review of the forecast and then publishes on average how accurate the forecasts tend to be. If anyone knows please let me know.

Before looking at why longer-term forecasts are less accurate than current forecasts, lets looks at basic definitions on the types of weather forecasts made in relation to time:

A short-range forecast is a weather forecast made for a time period up to 48 hours.
Extended forecasts are for a period extending beyond three or more days (eg. a three to five-day period) from the day of issuance.
Medium range forecasts are for a period extending from about three days to seven days in advance.
Long-range forecasts are for a period greater than seven days in advance but there are no absolute limits to the period.

Weather forecasts still have their limitations despite the use of modern technology and improved techniques to predict the weather. For example, weather forecasts for today or tomorrow are likely to be more dependable than predictions about the weather about two weeks from now. Some sources state that weather forecast accuracy falls significantly beyond about 10 days.

Most important we want you to spend the least amount of money possible while you stay comfortable.

Aaron’s Mechanical Services: Can We Call Phoenix An Oasis?

If we look up the definition of an “Oasis” we find; a small fertile or green area in a desert region, usually having a spring or well. Something serving as a refuge, relief, or pleasant change from what is usual, annoying, difficult.  I don’t know about you but that sure describes the Phoenix Metro Area for me. Phoenix… an oasis in the desert.

We have been comparing our great weather for Boston over the last few weeks.  Yes, that isn’t really fair.  So we thought we would compare the Valley of the Sun with El Paso Texas this week. After all they are a relatively large southwestern desert city.  They lie south of Phoenix and even though they are somewhat higher you would think our temperatures would be very similar.  Many people think of an oasis is a very livable place.

El Paso, Texas


Phoenix, Arizona


As you can see, both of these cities are expecting some rain in the coming week. But look at the difference in our overnight lows. El Paso is running some nights that are twenty degrees lower than here in the Phoenix Metro area.

Phoenix is considered a very livable city. Livability is critical to the establishment of a sustainable community, if for no other reason than if it is not present people will not stay in the community. But 'livability' as a term is exceedingly difficult to define. For some, it is intrinsically tied to physical amenities such as parks and green space; for others to cultural offerings, career opportunities, economic dynamism, or some degree of reasonable safety within which to raise a family. 

Where livability is linked to sustainability and infrastructure issues it is normally as an alternative development model to the expansion of sprawling suburbs with low densities of both population and services and where infrastructure provision is costly to ecological, economic, and social capital.

One thing that makes many cities livable is a comfortable climate.  If parts of the year are such that you home and business needs to be climate controlled to be a comfortable temperature you need to have a reliable HVAC system. 

If you are looking for fast and fair HVAC service or replacement we want you to think of Aaron’s Mechanical Services.  We want you to stay comfortable all year round. Most important we want you to spend the least amount of money possible while you stay comfortable.

Aaron’s Mechanical Services: The Future of Heating and Cooling

Contemporary practice in heating, ventilation, and air conditioning (“HVAC”) is inadequate to fulfill the stringent demands of the 21st century. It can be deficient in comfort, ventilation, indoor air quality, fire safety and perhaps most important energy efficiency.

For several decades now, HVAC designers have known that they must make their systems more energy efficient, but combining efficiency with high standards of comfort and health has proven to be an elusive goal. It may seem that performance compromises are inescapable, but that is not true. 

Present problems stem from continuing along an evolutionary design path that took a wrong turn in the past.

How HVAC Reached Its Present State

The evolution of HVAC has not been a steady march toward systems that are ideal for today’s conditions. On the contrary, as in biological organisms, HVAC systems evolved in response to conditions that existed at various times in the past. As a result, HVAC has accumulated historical baggage that make s it poorly adapted to present conditions.

Contemporary HVAC began its evolution about 120 years ago, when centrifugal fans were introduced in the first large steel frame buildings to circulate outside air for the purposes of cooling, odor removal, and prevention of infectious diseases. In quick succession, these ventilation systems acquired additional functions and requirements. With each new requirement, variations of existing methods were attempted, and new problems usually accompanied them.

Steam heating coils were added, creating central forced-air heating. These introduced the problem of temperature control for individual spaces, which was met with manual dampers.

Soon, prior expertise in mechanical cooling for meat preservation, ice making, and beer brewing led to the addition of cooling coils in central systems. This increased the problem of space, temperature control further, as cooling became associated with uncomfortable “dumping” and stratification of chilled air.

The Solutions In Future HVAC

The accumulation of unsolved problems in contemporary HVAC requires us to stop and take a fresh look. While we exploit the lessons of past experience, we will abandon assumptions that are no longer relevant and change practices that fail to achieve optimum performance. HVAC today uses two broad approaches. For compartmentalized buildings, the dominant design approach is using centralized air handling systems that serve multiple zones. For smaller buildings, and for individual spaces whose conditioning requirements do not match the rest of the building, the dominant approach is using single-zone systems. The first step toward optimum HVAC is recognizing that multiple-zone air handling systems inherently cannot optimize all HVAC functions, nor can they operate with a high level of energy efficiency unless they seriously degrade the comfort and health functions of the systems. This is a theoretical limitation, not just a practical one. Therefore, multiple-zone HVAC systems must be abandoned. The need to abandon multiple-zone systems for ces HVAC to rely on single-zone systems. However, contemporary single-zone systems have serious shortcomings, to the point that they are widely viewed as inferior alternatives to centralized systems. Fortunately, the deficiencies of single-zone systems are curable. They result from lack of care in design and from inadequate evolution of the equipment.

Cool Arizona Places: Borden Milk Company Creamery and Ice Factory

The Borden Milk Co. Creamery and Ice Factory is a historical site in Tempe, Arizona. Built originally as an ice plant, it was altered to also produce pasteurized bottled milk. The Pacific Creamery Plant was sold in 1927, and it operated under the Borden name until its closure in 1953. The building stood empty until it was reopened as Four Peaks Brewery, a restaurant and regional brewery.

The Borden operation had enough impact on the city that a new park was designated "Creamery Park" in 1999.

The Creamery Complex on "Old Eighth Street" in northeast Tempe was built in 1892 as F. A. Hough's ice plant, but has been used mostly for processing dairy products. In its first ten years, it served as the Tempe Creamery and the Tempe-Mesa Produce Company. In December 1907, the dairy operation was acquired as a second location by the Pacific Creamery Company, a major California enterprise. The company promoted the fact that it invested in what is conceded to be one of the best equipped plants on the Pacific coast.

Employing about fifty people made it one of Tempe's largest employers. Pacific Creamery produced condensed milk, butter, cheese "and ice, having a capacity for ice manufacture of 15 tons per day and shipped its "product(s) throughout Arizona, New Mexico and Old Mexico. Ownership again changed in 1927 when the creamery was acquired by the Borden Milk Company who expanded and modernized the complex. Façades were updated to reflect the emerging popularity of Spanish Revival architecture. Borden continued operations for the next 26 years until it shut down in 1953. Through much of Tempe's history, the creamery was one of the largest employers in town.

Built in the Mission Revival style, the building is almost entirely red brick, with wooden ceilings and a glass clerestory reaching as high as 35 feet, supported by steel suspension. The nine buildings were listed on the National Register of Historic Places in 1984.

The current appearance of the Creamery Complex dates to 1927, when the original structure was remodeled and new buildings were added, doubled the size of the complex of nine buildings. At that time, the distinctive curvilinear parapet walls were added to the buildings, making it a perfect example of the Mission Revival style of architecture that was popular in early 20th century.

The building shows a variety of construction techniques using brick, reinforced concrete, concrete block, frame, and metal. The Creamery Complex, includes the Tempe Creamery Office at 1350 E. 8th Street which was built in 1915 in the Commercial Box style which provides a good example of the use of Prism block in commercial construction. This building was added to the Creamery Complex as a response to the increased spatial needs of the business.

Are You Still Using Heat With Our 40 Degree Temps

Tonight the National Weather Service forecasts that we will see lows, in some places across the Valley of the Sun, where the night time (early morning) lows can be in the high thirties to low forties.  Most cities across the country would love to see that temperature range for their afternoon highs, let alone their overnight lows.

Forty degrees Fahrenheit as a morning low feels very cool if not cold here in the Phoenix Area. So, when we ask if you are still running your furnace or heating system we aren’t kidding.

Have you compared your utility bills with those from the same period last year? If you are paying more it could be a good indicator that your heating system needs a yearly service call. Some furnace or HVAC brands require yearly service to keep your warranty in good standing.

Saving energy (think saving money) and safety are the two primary reasons for your yearly furnace, heating system tune-up. Did you know that a yearly tune-up also extends the life of your HVAC of heating system?

With the official start of spring just about a month away many folks just aren’t thinking about heating here in the Valley of the Sun. But chilly nights or days (with a storm or cold front pushing into the Valley) can run into mid or late March so heating needs for Phoenix Arizona can still be a concern for the next month.

One of the great things about Arizona is our diversity of climate.  If you want to go play in the snow you can go to Flagstaff. It snowed there yesterday, February 23rd, 2015.

Did You Know?

The latest a freezing temperature (32 degrees Fahrenheit) occurred was on March 31st, 1987.

The record low for Phoenix in February is 24 degrees in 1933.

The average low in February is 48 degrees.

According to the National Weather Service February 2nd, 1939 was Phoenix's snowiest day on record. Snow covered the city to a depth of .4 of an inch. Just so you don’t miss it that was 4 tenths or less than one half of an inch.

Beautiful Weather For The Valley of the Sun… Again

Before you say you have seen this before please don’t think we are just picking on Boston this year… but, well they have been in the news for their cold and snowy weather this year. We checked on them, again this week and the National Weather Service forecast is more of the same.  So we looked at their ten day forecast on weather.com to get a great image of their high temperatures in the next week.

Boston February 23rd to 28th


As you can see their best day looks like mid-week where they will be three degrees Fahrenheit above freezing as the daytime high. The worst of it seems to be tonight with five degrees below zero as the low temperature. Of course, with wind chill it will feel even colder.

Phoenix February 23rd to 28th


Here in the Phoenix Metro Area we are forecast to have a very normal last week in February. With one exception we will be in the seventies for our afternoon highs and our worst low looks like mid- forties on Tuesday night (OK early Wednesday morning). That mid-forties as a night time low will be about fifteen degrees warmer than Boston’s afternoon best high this week. I know kind of like comparing Apples and Oranges.

This kind of week is why we have our winter visitors and why many people move to and retire to the Valley of the Sun. Weather you just can’t beat seven months of the year and five months of Oh, thank God for Air Conditioning.

If we have a chance we promise to do this same comparison in the last week of July… After all fair is only fair.

Did You Know?

Boston, MA... 
Average annual precipitation - rainfall: 43.76 inches.
Average Days of Sunshine; - 98

Phoenix, AZ... 
Average annual precipitation - rainfall: 8.03 inches
Average Days of Sunshine; - 330

Two Considerations When Choosing a New HVAC System

If you’re like most of us who live here in the Valley of the Sun, you probably just ignore your air conditioner, at least, that is, until it stops working. Then, you want it fixed, like now, like yesterday, if not sooner.

But taking the time to understand certain air conditioning terms before you fix (or especially replace) your air conditioner can make all the difference in your long-term electricity costs. Understanding the following two terms will allow you to save thousands of dollars next time you replace your unit.

Seasonal Energy Efficiency Ratio

SEER is a measure of a system’s efficiency. The more efficient the system (higher SEER number), the cheaper it is to operate. (And more energy-efficient systems are also better for the environment, so it’s a win-win.) The U.S. Department of Energy states that 13 is the minimum SEER rating for systems produced today (some older ones have ratings of six or less). A unit with a SEER rating of 16 or more could save you about $415 a year (compared against an older, low-efficiency model).

As you might guess, higher-SEER models are also more expensive. The ideal balance for your home will depend on where you live and how often you use air conditioning.

Heat Pump

A traditional air conditioner uses a refrigerant cooling system. The coolant in the coils cools down the air, which is then forced into your home. As you might imagine, this takes a ton of energy.

A heat pump, on the other hand, actually pulls heat out of the air inside your home and dumps it outside. (It can also be used for heating by gathering warmth from outside and funneling it into your house.) This is a much more efficient way to transfer heat and can save you up to $750 a year.

Heat pumps are efficient enough for both cooling and heating in our milder climate. In general this works well in the Phoenix Metro area. You may want to consider a dual-fuel system, which uses the heat pump in spring, summer and fall, but runs a gas pack backup for the very coldest days during our December and January nights.

If you do choose a heat pump, do your research, as there are different types. A geothermal heat pump, for instance, uses the relatively stable temperature underground to provide heating and cooling, but these systems are quite pricey and are more difficult (think expensive) to retrofit to an existing home system.

Cool Arizona Places: Petroglyphs of Signal Hill

Petroglyphs carved into Signal Hill in Tucson's Saguaro National Park West are a perfect example. Believed to be about 1,000 years old, the symbols etched into a pile of boulders there depict what appear to be animals interacting with esoteric circles and spirals. They've been attributed to the mysterious Hohokam or "those who have gone," a title applied collectively to a Native American culture that virtually disappeared around the 15th century. The images are assumed to closely represent the people who left them, yet after much study, nobody can be sure they actually mean anything.

Experts have speculated over religion, ceremony, medicine and historical record as influences, but as suggested before, the figures may just be the result of boredom. Pointlessly chipping away at rocks for hours seems a little gratuitous, though, when there are chores to be done. Like finding food in the desert, for example.

On the other hand, the petroglyphs' meaning might be hidden right in the shadows. Before his death in 2004, retired technical photographer and Tucson resident Nile Root believed he had quite possibly unlocked Signal Hill's secret. After studying the symbols throughout the last years of his life, he came to the conclusion that the puzzling pile of rocks was an elaborate timepiece.

A number of sites in Arizona have been proposed as ancient solar calendars, but if Root was right, Signal Hill could trump each of them in complexity, or at least imagination. Upon casual observation, the petroglyphs appear to be applied arbitrarily across randomly scattered boulders. After careful examination, however, it appears the glyphs were integrated with the natural play of sunlight amid the boulders' gaps and tapers.

For example, Root noticed that during sunrise on the vernal and autumnal equinoxes, two separate glyphs that appear very much like representations of the sun are "pierced" by similar spearlike shafts of light created by adjacent rocks. Another symbol,

concentric circles connected by radiating lines, appears to act as a sundial. When Root realized the boulder on which it's engraved leans at 32 degrees, the site's latitude, he placed a small stone in the inner circle. The subsequent shadow interacted with the lines to track seasons and upcoming equinoxes; it disappears at exactly midday.

The most prominent symbol, a large spiral etched into Signal Hill's tallest stone, appears to link with the site in multiple ways. At noon on the equinoxes, shadow divides it in half. At sunrise on the summer solstice, a pointed silhouette meets the spiral's center just as the rest of it becomes bathed in light. On the winter solstice, if one stands at the center stone in a small, circular clearing, the spiral aligns precisely with the sunrise. Additional icons appear to correlate with the spiral and aid in the tracking of lunar events, as well.

Location: Western District of Saguaro National Park just west of Tucson on Ina Road

Valley of the Sun We Are In-between Heating and Air Conditioning

With our afternoon highs running just above eighty degrees and our morning lows in the mid to upper fifties you may think that our blog would be out of things to talk about that are either heating or air conditioning related.

Nothing could be further from the truth. This actually the perfect time of year to have either your heating or cooling system serviced or replaced.

1. HVAC contractors are not swamped right now with service requests.
2. Your attic is not yet hot enough to melt metal or have your service tech baked.
3. Many time prices on parts and equipment are at their lowest.
4. You have time to consider your options.
5. You can see if your utility company has rebates for new equipment.
6. There MAY be federal or state programs in place to help defer your costs.
7. Check new regulations that exist or are just about to be implemented to see what they affect.

By replacing your system in the spring you put time on your side.  Time to research the type of equipment that would be best for your situation instead of just replicating whatever you had before.  

Spring replacements also give you time to search for the best contractor in the area to do the installation and chances are, since contractors are in between the cooling and heating seasons, they will be much more available and willing to spend time with you to help you figure out the best ways to solve your cooling problems.  

Since investments in new HVAC systems can be significant, this time might also allow you to line up financing and maybe cover it under a home equity loan and save on financing costs.

If you have Aaron’s Mechanical Services check your AC system in the spring, you both might have time to have him run some new calculations on both the actual cooling requirements for your home as well as the ductwork and airflow calculations.  A lot might have changed with your home since that old HVAC system was installed and these changes can affect both the size and type of system you now need to adequately cool and heat your home.  For example, if you added insulation, or upgraded to more efficient windows, knocked out some walls or added a room, you might need a different system size.  If you get the wrong size system you could have two problems.  First, if your system is too small it won’t keep up on the hottest days.  If your system is too large it will cycle too much and will cause wide swings in your indoor temperature and if you live in an area where humidity levels can be high it will not remove all the humidity from your home and you will have problems – especially at night, when you are trying to sleep.  Also, if you have kids going away to college and you want to shut off the AC vents in their rooms while they are gone, you might be better off with a system that has at least two steps of capacity modulation or you will run into the same problems as having the wrong size system.  Closing room vents and doors effectively makes your house appear smaller to your HVAC system and in addition to comfort problems you could even do significant damage to the system or cause it to fail prematurely.
