LEAF GUARDS


What is a leaf guard? Very simple. The leaf guard is a protective material placed over the outdoor condensing unit top grate. The material should have openings large enough to let air escape so as not to damage the unit. The material we use has a 1/4" opening and is an ultraviolet rated mesh (polyethylene resin). We cut it to fit the size of your grate on the outdoor condensing unit. This leaf guard protects the components in your outdoor condensing unit by stopping twigs, rocks, leaves, etc. from entering. Leaves can sit in the bottom of the unit and cause rust, twigs can get stuck in the fan blade, and rocks can do considerable damage. When the leaves collect in the bottom of your condensing unit, it enable small rodents to nest and cause damage to the wiring. This is a very inexpensive product to help protect your condensing unit. Give us a call and we can give you a quote.

NEWS FROM HONEYWELL


Some very interesting news from Honeywell:
Honeywell's Programmable Thermostats Edge Out Competing Products in Features, Rates Favorably on Other Factors

In Frost & Sullivan’s survey of 1,013 U.S. homeowners, 646 owned programmable thermostats and rated various brands on several specific points. Homeowners using Honeywell programmable thermostats rate their thermostats higher than users of any other major brand. “Honeywell users appreciate the features offered by its brand – 33 percent cite that having the ‘best features’ is their main reason for using Honeywell, compared to nine percent among users of other brands stating the same,” said Christina Alfaro Research Analyst with Frost & Sullivan’s Customer Research Team. “Supporting Honeywell’s overall best rating is that it rated well for other factors too, such as ease-of-use, energy efficiency, and cost savings.”

Honeywell conducts extensive – and on-going – customer research to ensure the products they develop are simple-to-install and are easy-to-use. For instance, their Prestige™ programmable thermostat incorporates a patented, interview-based interface that walks a homeowner through the set-up process by asking a series of questions, such as “what time does the first person wake-up in the morning?” or “what time do you go to sleep at night?” The answers help the thermostat program itself – no owner’s manual is needed. The graphic user interface displays information in an easy-to-understand format, the on-board user’s manual provides definitions and directions for each display screen and can be customized to display in English, French or Spanish.

Some Honeywell programmable thermostats also have the ability to wirelessly communicate to accessory devices using the company’s RedLINK™ technology, the first wireless protocol developed exclusively for the HVAC industry. The thermostat can be used with an outdoor sensor that sends a signal to the thermostat to display outdoor temperature and humidity on the home screen. This makes it simple for the homeowner to get access to that information.

RECLAIMING R-22 REFRIGERANT



With the impending phaseout of R-22 looming, the price and availability of the product will soon make it impractical to use.

With virtually tens of millions of R-22-designed a/c systems in operation, refrigerant users and equipment owners will need to employ a number of alternative options to satisfy their cooling needs. Due to the special application designs and cooling requirements found in multifamily structures, there are a unique set of challenges in maintaining cooling equipment and fewer practical options.

It is illegal to purposely vent any refrigerant. All refrigerant users must possess an EPA 608 certification (required by law under The Clean Air Act) to recover all refrigerants. Recovered refrigerants are to be recycled or returned to an EPA-registered reclaim service provider.

The law does allow equipment owners to recycle and reuse refrigerants in their own equipment without processing it through a reclaim company. However, this practice adds additional costs in the form of equipment, labor, and energy, and, if done improperly, can create additional service problems and even equipment failures.

HOPEFULLY SPRING IS ABOUT TO SPRING



Like any type of heating and cooling equipment, maintaining your heat pump is essential to keep it in top working order.

It’s easy to neglect your heat pump and postpone maintenance, but once you realize why regular service is so important, you’ll never miss a routine appointment again.

Regularly maintaining your heat pump provides the following benefits:

• Greater energy efficiency: A heat pump that is serviced every six months operates more efficiently than one that never receives professional tune-ups. Inspections that improve heat pump efficiency include changing the filter, sealing ductwork leaks and verifying proper refrigerant charge.

• Longer equipment life span: A well-maintained car can last years longer, and the same is true of a heat pump. Tightening electrical connections, replacing worn belts and cleaning the indoor and outdoor coils are all measures that protect system components and help them last longer.

• Lower energy consumption: More efficient heat pumps consume less electricity, which lowers your bills and helps the environment. Fixing refrigerant leaks, checking electrical connections, checking amperage, and cleaning away dirt all help to lower energy consumption.

• Improved comfort: A few adjustments and inspections can improve the heating and cooling output of the heat pump, helping you feel more comfortable in any season. Measures that improve your comfort include verifying correct electric control and ensuring that no return and supply registers are blocked, a just a few.

These types of inspections take place during professional tune-ups. However, there are things you can do on your own in between professional maintenance visits that provide similar benefits. These include:

• Changing the filter

• Keeping plants and other vegetation trimmed back from the outdoor unit

• Cleaning supply and return grilles and making sure they’re not blocked

Make sure you give us a call and set up your maintenance.

WHAT TO LOOK FOR IN A HEAT PUMP



When you start shopping for a heat pump, there are a few things you need to look for. First, manufacturers rate the efficiency of most heat pumps in two ways: SEER and HSFP ratings. Higher SEER and HSFP ratings indicate a more efficient unit.
•SEER stands for seasonal energy efficiency rating, and is a ratio of how much energy (measured in BTUs) is pumped outside in cooling mode divided by the electricity used (in watts) for cooling. Look for a SEER rating between 14 and 18.
•HSFP stands for heating seasonal performance factor. It calculates the ratio of energy pumped indoors for heating to energy used for heating, but it's a more complicated equation than the SEER rating because it also takes into account supplemental heating needs and the energy used to defrost the unit. Look for an HSFP rating between 8 and 10.

Heat pumps often feature options that make them more efficient. These include:
•A desuperheater coil that heats water by recycling waste heat (or on an RCC system, a refrigerant heat reclaimer that also uses the pump's extra capacity to heat water during mild winter weather).
•Dual-mode compressors and motors that save energy by adjusting up or down according to the level of heating or cooling needed.
•Scroll compressors that are quieter, more efficient and last longer than traditional compressors.

Though many of these features can only be found on more expensive heat pumps, they make up for the initial expense by helping heat pumps work more efficiently and save more energy throughout the pump's life.

TRANE'S HISTORY



Information straight from the Trane site that we thought would interest our readers.

For more than a century the Trane name has identified products and technology that stretched the world's idea of what was possible – a tradition that's still very much with us.

In many ways Trane is a classic American success story that grew into a global one. It began with our founder, James Trane, a Norwegian immigrant who opened his own plumbing shop in La Crosse, WI, in 1885.

With the inspiration of cold Wisconsin winters, James Trane invented a new low-pressure heating system he proudly called the Trane Vapor Heating System. His son, Reuben, was just back from college with a degree in mechanical engineering, so father and son began manufacturing operations in 1910 and incorporated as The Trane Company in 1913. It was Reuben's invention of the convector radiator in 1923 that firmly established the company's reputation as an innovator, a reputation Trane people have been building on ever since.

Growth through innovation

The idea of using technology to give people relief from summer heat was a radical and unproven idea when Trane became an air conditioning pioneer in 1931.

Trane fundamentally changed the concept of air conditioning large buildings with the 1938 launch of Turbovac, the industry's first hermetic, centrifugal refrigeration machine. This was the beginning of a long chain of innovations leading to Trane's current CenTraVac®, the industry standard for large commercial air conditioning systems. This is the most energy efficient system available anywhere for large buildings and it has earned Trane the "Best of the Best" Award from the U.S. Environmental Protection Agency.

Expanding our offer to customers

With the acquisition of Sentinel Electronics in the late 1970s, Trane moved into the important building automation and management field. The company was the first to offer integrated controls for all its products and became a leader in the still new field of energy management, a leadership position that continues to expand.

Our days as a leader in residential air conditioning began in 1982. That's when we took advantage of an opportunity to acquire General Electric's Central Air Conditioning Division.

We're proud that over the decades we've enriched the scope of our products and technology as well as the scope of the total solutions we can offer each customer.

In 1984 Trane was acquired by American Standard Companies and remained the largest of its three businesses: Air Conditioning Systems and Services, Vehicle Control Systems (WABCO) and Bath and Kitchen.

On Nov. 28, 2007 we successfully completed a plan announced the previous February to separate the three American Standard businesses, leaving each free to concentrate exclusively on the markets it knows best. Over the course of the year WABCO was spun off as an independent corporation and Bath and Kitchen was sold to Bain Capital Partners. On Nov. 28th American Standard Companies changed its name to Trane, reflecting our business focus and our leadership in providing integrated heating, ventilation and air conditioning services and solutions..

On June 5, 2008, global diversified industrial company Ingersoll Rand acquired Trane, furthering its transformation into a multi-brand commercial products manufacturer serving customers in diverse global markets, and away from the capital-intense, heavy-machinery profile of its past. With Trane now part of the family, Ingersoll Rand is better able to provide products, services and solutions to enhance the quality and comfort in homes and buildings, and enable companies and their customers to create progress.

Some of Ingersoll Rand's other brands include Club Car golf carts, Hussmann stationary refrigeration equipment, Ingersoll Rand industrial equipment, Schlage locks and Thermo-King transport temperature-controlled equipment.

New chapters in Trane's history of growth through innovation are being written every working day. Now as part of Ingersoll Rand, our momentum continues to build because - as our people have said for years - "it's hard to stop a Trane."

AN INTRODUCTION TO:


How heat pumps achieve energy savings and CO2 emissions reduction.
This section gives a brief introduction to heat pumps. Based on six basic facts about heat supply the value of heat pumps is discussed. It is argued that heat pumps are very energy efficient, and therefore environmentally benign.
An efficient technology.
Heat pumps offer the most energy-efficient way to provide heating and cooling in many applications, as they can use renewable heat sources in our surroundings. Even at temperatures we consider to be cold, air, ground and water contain useful heat that's continuously replenished by the sun. By applying a little more energy, a heat pump can raise the temperature of this heat energy to the level needed. Similarly, heat pumps can also use waste heat sources, such as from industrial processes, cooling equipment or ventilation air extracted from buildings. A typical electrical heat pump will just need 100 kWh of power to turn 200 kWh of freely available environmental or waste heat into 300 kWh of useful heat. For more information about the technical aspects of these energy savings are achieved, see the section Heat pump technology.
Six basic facts about heating.
Through this unique ability, heat pumps can radically improve the energy efficiency and environmental value of any heating system that is driven by primary energy resources such as fuel or power. The following six facts should be considered when any heat supply system is designed:
*direct combustion to generate heat is never the most efficient use of fuel;
*heat pumps are more efficient because they use renewable energy in the form of low-temperature heat;
*if the fuel used by conventional boilers were redirected to supply power for electric heat pumps, about 35-50% less fuel would be needed, resulting in 35-50% less emissions;
*around 50% savings are made when electric heat pumps are driven by CHP (combined heat and power or cogeneration) systems;
*whether fossil fuels, nuclear energy, or renewable power is used to generate electricity, electric heat pumps make far better use of these resources than do resistance heaters;
*the fuel consumption, and consequently the emissions rate, of an absorption or gas-engine heat pump is about 35-50% less than that of a conventional boiler.

HEAT PUMP INFORMATION


What is a Heat Pump
A heat pump is a device that moves heat from one location to another using a small amount of energy. It is often used in moderate climates and uses the air temperature difference between indoor and outdoor air to cool and heat your home. While an air conditioning system generates heat, the heat pump moves heat, this way being more energy efficient. Heat pumps can provide up to four times more energy than they use.
How a Heat Pump Works
Naturally, heat flows to a lower temperature from a higher one. With the use of a small amount of energy--electricity, fuel, high-temperature waste heat--a heat pump forces the heat flow into the other direction. A heat pump transfers hot air from sources like surrounding air, ground, water or waste into a building. When it cools a building, the heat is transferred into the opposite direction.
Technology
There are two main types of heat pump technologies used: vapor compression and absorption cycle.
A vapor compression system consists of the compressor, expansion valve and two heat exchangers (evaporator and condenser). The absorption system consists of the absorber, solution pump, generator and expansion valve.
The vapor compression process: the evaporated refrigerant liquid is transformed to hot vapors. The vapors enter the condenser and are transformed into hot vapors. The hot vapors give off the useful heat and are expanded to the evaporator pressure. Finally the working liquid returns to its original state.
Types
The heat pump can be categorized according to the heat source used. The most commonly used type is the air-source heat pump. As the name suggests, it transfers heat from outside air. The disadvantage of this type of pump is that it can only be efficient in moderate climate conditions.
A more efficient type is the geothermal heat pump that transfers heat from nearby ground source or water source. The installation costs more for geothermal pumps compared with air-source pumps, but have lower operating costs, as the ground or water has a constant temperature. This type of pump can be used in more extreme weather.
Other types include the ductless mini-split heat pump--for homes without ducts--and the reverse cycle chiller pump--a type of air-source heat pump that generates hot and cold water.
Performance
The performance of a heat pump is the difference between the energy used and generated energy. A heat pump can generate 100 kWh (unit of power: kilowatts per hour) using just 20 to 40 kWh of electricity. An industrial pump can generate the same amount of heat using only 3 to 10 kWh of electricity, according to heatpumpcentre.org.
Due to the low consumption of primary energy, a heat pump reduces the gas emission that harm the environment --carbon dioxide, sulphur dioxide, nitrogen oxides.

Advanced Features to Look for in a Heat Pump



A number of innovations are improving the performance of heat pumps.

Unlike standard compressors that can only operate at full capacity, two-speed compressors allow heat pumps to operate close to the heating or cooling capacity needed at any particular moment. This saves large amounts of electrical energy and reduces compressor wear. Two-speed heat pumps also work well with zone control systems. Zone control systems, often found in larger homes, use automatic dampers to allow the heat pump to keep different rooms at different temperatures.

Some models of heat pumps are equipped with variable-speed or dual-speed motors on their indoor fans (blowers), outdoor fans, or both. The variable-speed controls for these fans attempt to keep the air moving at a comfortable velocity, minimizing cool drafts and maximizing electrical savings. It also minimizes the noise from the blower running at full speed.

Many high-efficiency heat pumps are equipped with a desuperheater, which recovers waste heat from the heat pump's cooling mode and uses it to heat water. A desuperheater-equipped heat pump can heat water 2 to 3 times more efficiently than an ordinary electric water heater.

Another advance in heat pump technology is the scroll compressor, which consists of two spiral-shaped scrolls. One remains stationary, while the other orbits around it, compressing the refrigerant by forcing it into increasingly smaller areas. Compared to the typical piston compressors, scroll compressors have a longer operating life and are quieter. According to some reports, heat pumps with scroll compressors provide 10° to 15°F (5.6° to 8.3°C) warmer air when in the heating mode, compared to existing heat pumps with piston compressors.

BALANCING or AIR BALANCING



Air Balancing, Digital Flowhood Testing(Adjusting air flow throughout a home)
Air balancing is a scientific way of adjusting the air flow evenly throughout the home or office using several available tools within the heating and air conditioning industry. Unlike big commercial buildings, residential duct systems were never engineered or balanced to properly distribute the air where it's needed in the home. This makes some rooms too hot or too cold. Air balancing is rarely performed in new construction or tract housing which leaves most homeowners wondering why they are uncomfortable in certain areas of their home.

What it takes to achieve even air flow.
Inspect your existing heating and air conditioning equipment, duct system and test your current air flow distribution system using a air flow capture hood.

What's a Air Flow capture hood?
These are essential computerized instruments for diagnosing uneven air flow. It measures the existing air flow coming out of the register vents in a measurement of cubic feet per minute (CFM) and we document those readings.

Make recommendations to correct the problem.
Usually, it is possible to use the existing duct system, or modify the main branch ducts to the proper size. In some cases it's requires that we replace the entire duct system, due to duct leakage or various design issues that can't be corrected properly to overcome the deficiencies. In either case we are installing air balancing dampers in each final duct branch run so the airflow can be adjusted properly.
