  • Energy Efficiency – Easy Ways To Reduce Your Air Conditioning Use And Save Money

    Posted on February 21st, 2010 Sam Greyhawk No comments

    Did you know that 14% of the energy produced in the United States is used to air condition buildings and 10% of the energy produced is used to air condition homes? What is the total cost to consumers? Over 15 billion dollars a year. To put that into perspective the American Council for an Energy-Efficient Economy (ACEEE) equates that to an astounding 140 million tons of CO2.

    Energy efficiency refers to the reduction of energy used by specific end-use devices and systems, such as air conditioners, typically without affecting the quality of the services provided. Energy efficiency can be achieved many ways. In the case of your air conditioning one simple way to achieve this efficiency is by reducing your air conditioning needs.

    Reducing Your Air Conditioning Needs

    Depending upon where you live you may feel very dependent on your air conditioner. You may even be thinking about upgrading to a newer air conditioner with higher improved SEER (Seasonal Energy Efficiency Ratio) but before you do consider the following – the easiest way to save money and energy on cooling is to reduce your air conditioning needs in the first place.

    While some of my solutions may seem initially costly – in the long run you will enjoy a monthly energy savings, in some cases you may appreciate the value of your home, and you will always feel good knowing that you are doing your part to fight global warming.

    Strategies for Reducing Your Air Conditioning Needs

    • Invest in alternate forms of in-house cooling such as ceiling fans or house fans. Unless you live in a very humid climate than ceiling fans, which can provide cooling by creating a low- level “wind chill” effect, are a good and relatively inexpensive choice. Ceiling fans are also rated by Energy Star so it’s easy to find energy efficient models. House fans are usually large fans in your top-floor ceiling. They cool by expelling hot air out and in-turn creating a vacuum that sucks cooler air in. Unfortunately house fans are not covered by Energy Star. In either case fan use substantially less energy then air conditioning systems and can go a long way in reducing your dependence on your air conditioner.
    • Replace older single pane windows with newer more energy efficient double pane or even triple pane windows. More energy efficiency windows can reduce your air conditioning needs but depending upon the number of windows involved it may get expensive. If expense becomes a concern you can always opt to use drapes or window coverings that block out the sunlight effectively. While drapes and window coverings will help, for the best results when justified, I recommend replacing the framing and glass. In some cases replacing your windows can improve their energy efficiency by up to 41% in the summer – when your air conditioning is used most.
    • Consider shade gardening. If replacing your windows is expensive but you have room for gardening consider planting shade trees on the sunny side of your home. The less direct sunlight that gets into your house, the less heat. Shade trees also have the added benefits of reducing local area CO2 pollution. You can expect a full grown shade tree to gradually remove about 10 lbs of CO2 a year, native trees are always good choice because they are easier to maintain.
    • Replace non-programmable thermostats with programmable versions. You can save as much as 10% a year on your cooling bills by using a programmable thermostat to adjust the temperature automatically while you regularly sleeping or out of the house. When you shop for a programmable thermostat, be sure to look for the Energy Star versions.
    • Install energy efficient roofing. Energy Star offers a number of different Reflective Roof Products that can reduce your peak air conditioning demand by as much as 10-15%.
    • Use light-colored or “cool” sidings or paints with a high Light Reflective Value (LRV). Most major paint manufacturers can tell you the LRV of any color paint chip. The higher the LRV the more the paint will reflect away heat instead of absorbing it. Keeping your house cooler by reflecting away heat will reduce your air conditioning needs.
    • Replace your older/inefficient appliances such as old or secondary refrigerator or, replace incandescent light bulbs with LEDs. The less heat your appliances and inefficient lighting give off the less your air conditioner will have to compensate.
    • Unplug large consumer electronics when you aren’t using them. Lots of newer electronics have a “sleep mode” that keeps them ready for action. This “sleep mode” uses electricity and because the device is running at some level it will still be creating heat. When not in use,don’t forget to unplug chargers for your smaller devices, too
    • Properly insulate your home. If you have a home that isn’t properly insulated you can waste a lot of electricity when the cool air created by your air conditioner escapes. Why? Your air conditioner will simply keep working harder to maintain a stable temperature regardless of continuous air leaks. The harder your air conditioner works the more electricity is uses and the more expensive it becomes. If your home has an attic it is very common for air leaks to occur between your living space and the attic space.

    An easy way to save money on air conditioning which is often overlooked is through the simple reduction of its use. While enjoying the cool benefits of air conditioning it is easy to overlook its expensive nature, due to the electricity required one has to also consider it’s environmental cost. While being green isn’t always easy, in this case, being green will save you money – by reducing your energy usage.

  • Air Conditioning Installation and Heat Installation

    Posted on February 21st, 2010 Ricky Lim No comments

    Air conditioning installation and heat installation are one of the most important home appliances that need to be setup in a house. It is important to understand how important air ventilation is to a house and how to heat your house evenly especially during winter months.

    Generally, when building a house, the engineers will take into consideration the HVAC, heating, ventilation and air conditioning requirements already.

    For heating units in your home and for most buildings, engineers will often use gravity to circulate the air. Furnaces usually are placed at the bottom of a building with ductwork constructed to carry the heat to the upper floors.

    As the air start to cool on the upper floors, it will automatically be moved back down to the furnaces by gravity. By using such as a theory, it can help save power bills and still be able to heat and cool the entire home or building easily.

    To install a furnace, you need to get a licensed electrician or a certified plumber as incorrectly installed ones can pose a danger to its occupants. So make sure to get a certified air conditioning and heating electrician to do the job.

    For all air conditioners and heating equipment, proper air venting is important. It is not only to improve the efficiency of your air conditioner or heater but also because of safety.

    A heating system can produce dangerous toxic gases such as carbon monoxide which can pose great danger if it is not redirected out of your house or building through properly installed air ventilation ducts.

    Air ventilation ducts can also help redirect the heat away from the house to help improve the efficiency of your air conditioner unit.

    Without proper ventilation, your air conditioner is just wasting energy compensating for the hot air it is generating.

  • Are You Still Paying Huge Air Conditioning Bills? Call in the Professionals

    Posted on February 20th, 2010 Thomas Yoon No comments

    A well-maintained air conditioning system will use 15% to 40% less energy than a neglected one. Do you need a professional to help you achieve this savings?

    I have discussed in another article that there are some simple actions that you can do to improve on or to maintain the efficiency of your air conditioning units, but when it comes to highly technical tasks, it is best to leave them to the experts.

    Air conditioner adjustments and repairs should be done by professionals. An air conditioning unit is much more complex than it seems. There are refrigerant gases, brazing joints, compressors, fans, coils, fins, electrical starters, thermostats, overload switches, filters, dryers, lubricating oil, drain pans, insulation, mountings, control systems, remote sensing, and many other components that an air conditioning technician needs to understand.

    In addition, there are tools specially made for air conditioning work – flaring tool, tube bender, cutter, gas charging manifold, vacuum pump, fin comb, coil cleaning chemical, ratchet socket wrench, brazing torch, solder, voltmeter, clamp meter, and many others.

    When the air conditioning unit needs servicing, a professional service technician should clean the evaporator and condenser coils, check refrigerant pressures, and adjust and lubricate moving parts. If there is not enough refrigerant gas, the system needs to be topped up. This can only be done by checking on the pressures in the system. He will also look for other symptoms that can lead to failure or inefficiencies and then rectify them.

    If you have a packaged system, the technician will help to inspect the duct damper and if necessary, repair or replace it. Air conditioning systems that share ductwork with a furnace must have a damper in the duct. It prevents cool air from entering the furnace cabinet in summer, and warm air from escaping to the air conditioner in winter. A missing or malfunctioning damper can waste tremendous amounts of energy and lead to corrosion of the furnace. This has to be rectified.

    How often do you need to call in the professionals? It really depends on how much your cooling system operates. As a rule of thumb, you will need to call them in at the following recommended intervals:

    Hot regions (operating 8 or more months per year) – once a year.

    Warm regions (operating 5 to 8 months per year) – every 2 to 3 years.

    Cold regions (operating less than 5 months per year) – every 3 to 5 years

    Sometimes, just maintaining the cooling system is not enough. You may need to replace the air conditioning system with newer equipment. Air conditioner replacement makes sense if:

    • The air conditioner is over 10 years old.
    • The air conditioner efficiency (SEER or EER) is below 7 or 8.
    • Repairs or modifications of an existing unit will cost more than half as much as a replacement.
    • The unit does not operate properly and can’t be fixed.
    • You’ve sealed your home’s walls, floor, ceiling and ducts, installed storm windows, and performed cooling system maintenance, but still can’t keep your home cool.

    These are some of the things that a professional can help you:

    Replace the air conditioning system

    In some situations it makes better sense to replace an older air conditioner with a new, high-efficiency unit. Air conditioner replacement should be considered if the existing unit is worn out, inefficient, or significantly oversized.

    Repairing an existing air conditioner may seem to be the least expensive option, but it may cost more in the long run. Paying for repairs on an older, inefficient system may simply prolong the inevitable need for replacement. Installing a new, energy-efficient system may be much more cost-effective. A cooling system technician can help you evaluate whether a new air conditioning system is appropriate.

    Sizing your air conditioner.

    Bigger is not always better when it comes to your air conditioner. For starters, oversized equipment can be less effective at dehumidifying your house. Not only can this lead to moisture problems in a home, but the higher humidity may force you to lower the thermostat to achieve the same comfort level — increasing your energy use. An oversized unit also cycles on and off more frequently, which increases wear and tear, shortens the service life, increases the frequency of repairs, and reduces efficiency. Plus, it costs more to purchase oversized equipment in the first place. If purchasing a new air conditioner, cooling loads should be carefully calculated by your equipment supplier.

    Evaporative coolers.

    If you live in a hot, dry climate, such as the Southwest, an evaporative cooler (swamp cooler) may be a good alternative to a refrigerant-cycle air conditioner. Evaporative coolers use considerably less energy than standard air conditioners. Check with a local air conditioning contractor to find out if such a system makes sense for your home.

    An air conditioning system professional’s advice and expertise is certainly needed when you have to deal with such complex designing, installing and commissioning works like these. It will certainly pay you back in the long run. Just leave it to the experts.

  • Helpful Tips to Choose a Quality Air Conditioning Installation Company

    Posted on February 20th, 2010 Mike Strobel No comments

    There are many ways to choose a company to install your new air conditioning system. Here are some of the things I would recommend checking:

    You will want to make sure that the company you choose is licensed and insured to perform the air conditioning installation. Many of the companies out there claim they are “licensed and insured” but I always like to see proof in writing. The reason the company needs to be properly licensed is because this allows them to pull the necessary permits and have the inspections completed by the city or township. It also shows that the company has the required training and experience to obtain the licensing, which means your job will be done to the code requirements.

    Make sure that the contractor is properly insured to perform your air conditioner installation; you’ll want to make sure that the air conditioning contractor carries a liability policy and also a workman’s compensation policy on his employees. This protects you the homeowner if something is to happen to your home or one of the contractors employees is hurt while installing you air conditioning system. I always want to see this in writing. If the contractor is not insured and something happens it can come back to your homeowners insurance or you personally.

    Also, ask a few questions about the companies hiring and screening process of their employees. You’ll want to look for a company that does background checks and drug screenings on their people. I like to have an idea of what type of people will be coming out to my house. There are many contractors out there that have no hiring policies in place. It makes you think about who you would allow in your home. Don’t forget to ask the contractor for referrals of customers where they have done a similar air conditioning job. Make sure to get the phone number and call their customer. Ask the testimonial a few questions to get a feel for the contractor that will be installing your air conditioning system and what you can expect from the contractor. I would recommend going and looking at the quality of workmanship if possible.

    I also would recommend visiting the Better Business Bureau website. They have made it extremely easy to check on any contractor by just typing in their company phone number. If they are members you see the company’s history, complaints, if any and how the complaints were resolved. This tells you a lot about how a company does business. This may not seem like an important thing to check but always check that the company actually has a real physical address and preferably an office at that location. There are many contractors who use post office boxes as their office. Where do you go if you do have a problem after the installation of your air conditioner? They are no where to be found. You will also want to look at the company’s years in business; this usually lets you know you are dealing with a company that has a reputation to protect. In this day and age the company should have a website for customers to gather information and learn more about them. You should consider this when making your choice.

    The last piece of information you will need to make an informed decision and pull everything together would be checking on their office staff, how the records of your air conditioner installation are recorded and maintained if they are needed in the future. How many service technicians do they employ in the event you need your system serviced in the future or a warranty issue arises? You can see that all of these things lead to the old saying “You get what you pay for”. If you are getting pricing on a new air conditioning system, think about all of the above reasons why that other contractor is cheaper. Is he really cheaper in the long run? Check as many of the items above as possible before making your final decision.

  • Higher SEER Replacement Air Conditioning and Heat Pump Systems

    Posted on February 19th, 2010 Mark Strahan No comments

    It is not unusual to find package and split system air conditioning units in the Phoenix market that have been in use since the 1970′s or 1980′s. Because the average life expectancy of this type of HVAC equipment is around twelve to fifteen years, it is high time to retire some of these tired old workhorses.

    An added bonus when you replace older air conditioning systems can be a significant increase in energy efficiency with an accompanying decrease in energy costs. With the amount of discussion we have been hearing in the news lately urging all of us to be green and save energy that is probably not going to be an unwelcome consequence.

    Along with the good news of energy savings there are also some considerations that the competent air conditioning contractor will make you aware of when it is time to replace older equipment. I would like to share a few of them with you. First let’s discuss split system heat pumps and then briefly cover things that are common to both package units and split systems.

    As SEER (Seasonal Energy Efficiency Ratio) ratings for new air conditioning equipment have increased, HVAC industry practices that have been marginal in the past will no longer be acceptable. One of those unacceptable practices occurred whenever split system heat pump condensing units were replaced. The common practice in the past was to replace the heat pump condensing unit without first verifying that the new condensing unit was compatible with the old air handler. Several problems may arise whenever there is a mismatch between the condenser and the indoor air handler.

    The first problem is the reduced efficiency that will result from replacing an older condensing unit without replacing the air handler at the same time. The reason for this is that air conditioning manufacturers do not rate current model heat pump condensing units with “antique” air handlers that are twenty years old. To achieve the published SEER, a heat pump condensing unit must be matched with an indoor air handler or fan coil unit that it has been rated with. In other words, if you install a new 13 SEER condensing unit with an old 8 or 9 SEER air handler, the actual efficiency achieved will be less than 13 SEER.

    A second concern is there can be a mismatch of the internal coil volumes between an older air handler and a newer condensing unit. As minimum SEER mandates have required increased efficiencies over the years, manufacturers have made enhancements to both the indoor and outdoor coils in order to increase heat transfer efficiencies. Newer condensing units may have a different internal coil volume than some of their antique counterparts. If a new heat pump condensing unit is installed on an old air handler it may result in improper operation in either the heating or the cooling mode that will require seasonal refrigerant charge adjustments and unnecessarily increase service costs. It can also contribute to system reliability issues.

    A third issue we are all facing is the difference in the characteristics of the refrigerants and compressor lubricants that are being used in the new systems. Since new air conditioning equipment using R22 refrigerant cannot be manufactured after 2010, the leading manufacturers have already started making newer high efficiency models utilizing R410a refrigerant and polyolester (POE) oils. The new refrigerant has properties that are very different than the R22 that has been the primary refrigerant for split system and package air conditioning systems for decades. In short, R410a is not compatible with the refrigerant flow control devices in the older air handlers that were designed for R22. Even if the flow control device could be changed, there may also be issues that could develop over time if the original mineral oils are not adequately cleaned from the system.

    A fourth consideration is the refrigerant line size. The new high efficiency R22 condensing units often require larger diameter vapor lines than those that were originally installed with the old system. It may not be economically feasible to replace the vapor lines, so there will be losses in efficiency as a result of the increased refrigerant pressure drop in the smaller than recommended vapor line. One possible solution to resolve this issue would be to install a new R410a split system condensing unit and a new R410a air handler. Since R410a generally requires smaller vapor lines than R22, it would allow the use of the existing smaller vapor lines. Recommended procedures for removing residual mineral oil from the existing lines would have to be observed if the conversion to R410a was implemented.

    When all of the above factors are taken into consideration, it becomes clearer that the very best course of action is to replace the indoor unit along with the heat pump condensing unit. While this is more expensive up front, it can help avoid significant downstream issues later.

    Now that we have discussed issues unique to split system replacements, let’s consider some factors that are common to both package units and split systems.

    One issue that is common to both package units and split systems in higher SEER products is reduced cooling capacity at higher outdoor temperatures. This can be verified by checking manufacturer’s ratings for the old air conditioning system and the new air conditioning system at outdoor temperatures above 100 degrees. The newer high efficiency systems generally tend to lose sensible cooling capacity more quickly than the lower efficiency units that were manufactured in the past. This is an important factor when evaluating an existing system that is doing only a marginal job of cooling the space it serves. A new system may have to be larger in capacity to produce the desired cooling effect at the higher outdoor temperatures we see in Arizona. There is a caveat with this also. You don’t want the replacement system to be grossly oversized either or it will not perform as intended.

    Another thing you will notice is that many of the newer systems have larger cabinets than the older style units. The larger cabinet size can become an issue in confined areas. Since minimum clearances must be maintained, a new system may not fit where the old system was installed. This consideration will be unique to each specific application, but you should be aware of it so you don’t get an unpleasant surprise.

    One last item to be aware of regarding both package or split system replacements is the significant difference in equipment costs. Higher efficiency comes with a higher price tag. Based on one leading manufacturer’s pricing for a 5 ton package heat pump, the jump from 10 SEER to 13 SEER comes with more than a 30% differential in price. If it has been a while since you have replaced an air conditioning system, you may have “sticker shock”. Material price increases along with the use of advanced technologies like variable speed compressors, dual compressors or unloading scroll compressors along with variable speed fan motors and enhanced control systems all contribute to higher equipment costs. Keeping this in mind when you are projecting future costs for HVAC equipment replacement can help you develop more accurate replacement budgets.
