Why do you need to have an energy efficient Air Conditioner

When monthly utility bills start shooting up, you realize that summer is scorching your pocket too! Thus relief lies in having an energy efficient Air Conditioning system which lets you manage the cooling level as per your needs; so that your monthly electricity bills are intact. A yearly assessment is suggested for AC systems which have started aging. Exorbitant energy bills and insufficient cooling are some indications to explore energy efficient cooling options for your home.

A simple replacement decision is not enough. It is very important to be armed with precise information which will help in purchasing an energy efficient air conditioner. The first step should begin from your home.

Know What your Home Needs

• Your home location; i.e. whether it experiences extreme/moderate weather conditions.
• What kind of home you live in, what is the total sq. ft., how many stories it has.
• Your standard comfort level i.e. whether you want extreme cold or excess warmth in your home.

Once these questions are answered, you will be able to shortlist the best AC system within your budget.

Types of Cooling Options

Window AC – Those who are followers of the old school method might prefer this cooling option. The best thing about a Window unit is that it is fairly inexpensive to purchase and really simple to install. However, such a system works best for single rooms but definitely not for the entire home. Unfortunately, it is not an energy efficient option which you realize once those seals start leaking, thereby allowing heat and moisture to seep through the room.

Central Air Conditioning – It helps to control even temperature throughout the house. Then this hidden unit, if properly installed, is a great value addition to your home. The only thing is that you should be prepared to spend a hefty sum for purchase and installation purpose.

The Split Air Conditioning system – It is the most convenient option for maximum homes. Energy efficient and easy to install, the split system cools your entire home thoroughly and quickly. Then there are units which come with special filtration and bacteria killing techniques thus presenting you with fresh indoor air. Some feel that if purchase costs are compared then the Spilt system is comparatively expensive than the Window one. However, the split AC emerges winner in the long run, since it keeps both your home and wallet cool!

Now that you have decided to install a new Air Conditioning system, the next prudent step is to consult any recognized air conditioning specialist for customized analysis of your home cooling needs. Accordingly, you should make the purchase/replacement decision.

What you should Know about Air Conditioning Filter

Talk about air conditioning components and the first which comes to mind is air conditioning filter. The AC’s performance depends a lot on how the filter is being maintained. A clean filter means you are breathing pure air whereas a dirty filter lets circulation of air filled with pollutants. Each part of the air conditioning system, be it ductwork or the air conditioning refrigerant, needs filter which is thoroughly washed.

What can happen if the air conditioning filter is not maintained properly?

Firstly it will place excessive stress on your monthly energy bills since the AC system works harder to keep the place cool. Since action of each air conditioning part is interlinked, an unclean filter puts greater pressure on other components, thus shortening their life spans. This is turn means the AC system might conk out anytime forcing you to spend more for repair and maintenance purposes. Finally, if you don’t want to compromise with your family’s health then give proper attention to the AC filter.

How often do you change it?

It depends on the AC load, e.g. for home cooling systems, changing the filter every month or alternate months will suffice. However, for commercial or industrial installations, this should be done every alternate week. Don’t wait till the filter turns pitch black with dirt. Rather, follow a proper maintenance schedule.

Sometimes performance of the filter depends on its brand too. You might find some brands sturdier than others. A good idea to judge the filter's ability is by assessing its Minimum Efficiency Reporting Value (MERV), which ranges between 1 to12. Higher rating ensures the filter is more effective in removing not only dust but also animal dander, mold, pollen and other allergens. In general, an air conditioning filter can screen out 3 to 10 microns of particles. A good idea is to consult an air conditioning specialist in this regard to know how often the AC filter should be maintained.

Ensure proper installation of the Air Conditioning Filter

If it is placed inaccurately or loosely, then the ultimate purpose of filtering is lost. Thus the filter needs to be placed in accurate direction which is usually indicated by an arrow marked either on the side or on the face of the filter. Air flow should be in the direction as indicated by the arrow. Then the air conditioning filter needs to be fitted tightly. A perfect seal prevents unfiltered air from seeping in and damaging your air conditioning system. Thus, it is always advisable to get in touch with an HVAC expert only for accurate fitting of the AC filter.

Five common types of air conditioning filters are available in the market. Conventional/ Pleated fiberglass disposable filters, Electrostatic filters, Electronic filters and Carbon Filter, of which the first two are generally used for home/office/industrial/commercial settings. Rather than trying it on your own, better get in touch with an expert to know what filter best suits your AC and how often it needs to be maintained/changed.

How to Reduce Air Conditioning Costs of Sizeable Homes

If you are the owner of a spacious home, then maintenance and consumption costs of the HVAC system must be a matter of concern. It is quite natural that the air condition costing of a three-storied house has to be greater than a two roomed flat. Does this mean you compromise with the comfort factor, fearing an exorbitant utility bill? Absolutely not! A study shows that by adopting a balanced scientific perspective you can easily save up to 20% in terms of monthly utility bills, irrespective of the home area. Some knickknacks can help you get some positive results:

Routine Cleaning of the HVAC Unit

This is one procedure which should be followed on a regular basis, especially for large buildings. A general cleaning helps remove dusts particles from air that could cause health hazards. Also the cleaning puts lesser pressure on the AC since dust-free air remains cooler and circulates faster throughout the building.

Check  Air Conditioner Unit Components

This should include a detailed checkup and maintenance of ducts, airflow gauges, air filter, coils and refrigerants. If needed, necessary repair/replacement should be done immediately. With this procedure the AC system can function better. Simultaneously energy consumption is reduced. Always keep in mind that delay in air filter replacement, duct status or refrigerant check means hike in electricity bill. At the same time, your AC maintenance costs shoot up too.

Now, that you are aware of basic guidelines, the next logical step is to consult a reliable and experienced HVAC contractor. It is very important to entrust the job to a qualified company only, if you are really serious about reducing carbon footprint. Primary responsibilities of the HVAC contractor are to provide fresh indoor air and keep energy consumption to a minimum level. Here are few aspects you need to assess prior to engaging a firm for AC installation/ upkeep of your expansive home.

• How long the company is in business?  A sound track record of at least over 20 years does help in offering specialized air conditioning assistance, especially for huge setups.
• Does the firm have technicians and installers who are properly certified and up-to-date with relevant information? This is one crucial factor which is to be verified. After all you don’t want to end up with incompetent technicians who have no idea if your AC needs filter replacement or coil cleaning!
• Is the company located at a convenient position? Do they respond promptly to your emergency call? A central location and an exemplary customer service mean the company technicians will be at your doorstep within minutes of receiving the emergency call.
• Does the company adopt a transparent approach while explaining its terms of services? Be it offering customized services for your three stored building or even a money back guarantee, everything should be explained clearly along with a written warranty, before taking up the project.

A prudent approach is the only way to tide over uncomfortable summer months with a comfortable utility bill.

Air Conditioning Requirements

Air conditioning is a necessity in certain parts of the United States while, heating arrangement is a must-have in some other areas. When it comes to air conditioning needs in San Francisco Bay Area, one thing can be said is that the requirement is not that intense as compared to the southwest or deep south. Actually residents of the Bay Area are blessed with quite a pleasant weather. Hence they don’t always require the same degree of temperature control as is needed in some other states. Residents in SF Bay Area can thus enjoy diverse air conditioning options. The ultimate aim of San Francisco air conditioning service providers is to guarantee the most pleasant living condition at your home within reasonable price.

Different Types of San Francisco Air Conditioning Options

In general, air conditioning options for San Francisco residents are almost the same as in other parts of the country. As mentioned, it is the moderate temperature of the Bay Area which makes it best fit for nearly every type of air conditioner that is available in the market. What is needed is to pick up an AC unit which is energy efficient, easy to maintain and  cost saving.

To ensure comfort in every room, central air conditioning is the most logical, efficient and cost-effective option.

The only problem with central AC is that if you are installing it for the first time then be prepared to spend a lump-sum amount. Since the installation for most central AC systems involves huge amount of ductwork, the overall process indeed comes at a price. Ductless or mini-duct AC is economical alternative for those who have limited budget. Again if you are already having the central cooling unit but thinking of upgrading it, then better try out a latest and efficient condenser. This will surely help improve the system performance and cut down your monthly electricity bills too.

Alternatives to Conventional Air Conditioning System

Bay Area residents are well aware of the changing temperature over there. It doesn’t vary dramatically but the weather condition still demands cooling in winter and heating in summer to maintain a pleasurable temperature inside the house  Thus many AC companies have come up with a unique concept whereby installing a single unit will serve both heating and cooling purposes. Since only one ductwork is needed in such units, that helps reduce installation costs. Only word of caution is that such system might not work in extreme weather conditions. However, keeping the moderate temperature of SF Bay Area in mind, such a unit should efficiently serve the basic purpose of heating and cooling throughout the year.

If you are interested in installing a new AC unit or want to modify the existing one, it is recommended that you consult any San Francisco air conditioning specialist for authentic opinion.

How a Typical Maintenance Checklist should Look Like

We dutifully keep a grocery list or a to-do list but for something that accounts for more than its fair share on our expense list, we simply leave on the back burner. Making a maintenance checklist spares your wallet and also avoids much confusion. With regular maintenance you can curb problems when small and ensure optimal performance of your HVAC system.

Here goes the checklist,

Check Thermostat Settings - The thermostat controls both the heating and cooling systems of homes with central heat and air conditioning. It detects the temperature of the room and compares it to the desired temperature setting. Set the thermostat at least 5 degrees higher or lower than your normal setting, depending on the season. Set it 5 degrees higher than normal during summer and 5 degrees lower during winter.

Inspect Electrical Connections - Measure voltage and current on motors. Faulty electrical connections can cause unsafe operation of your system and reduce the life of major components.

Lubricate Moving Parts - Oiling all moving parts can prolong the life of your HVAC system. Parts that are not lubricated may wear out faster leading to repairs. An ounce of prevention is worth a pound of cure in this regard.

Check Condensate Drain - A plugged drain can cause water damage in the house and affect indoor humidity levels in your central air conditioner, furnace and/or heat pump (when in cooling mode).

Clean Evaporator and Condenser Air Conditioning Coils - Over time the surfaces of these coils can become dirty as the air moving through the coils can contain dust, moisture and other contaminants. Clean coils save your utility bills; while, dirty coils consume more electricity.

Clean and Adjust Blower Components – Proper airflow reduces your system's efficiency up to 15 percent. So, keep a watch on the blower components always!

Check Gas (or oil) Connections, Gas Pressure, Burner Combustion and Heat Exchanger - Routine furnace maintenance and cleaning don’t require special skills. Just a few basic hand tools can do it for you. Improper gas (or oil) connections or cracked heat exchanger can make the equipment less safer and efficient.

Seal your Heating and Cooling Ducts - You would be shocked at how much heating and cooling escapes through your ductwork before it ever flows through your vents.

Clean/Replace your Air Filter Regularly - A dirty filter can increase energy costs leading to early failure. If you are using it more, check your filter every month as a dirty filter can slow down air flow wasting energy.

Carbon Monoxide (CO) detector - A furnace that is out of adjustment can leave CO in your home, this device can help protect from CO poisoning 

Over half of the energy used in your home goes to heating and cooling. So making smart decisions about your home's heating, ventilating, and air conditioning (HVAC) system can have a critical impact on your utility bills and your comfort. Take that first step to protect yourself, your loved ones and to secure your home.

When and why would you require a Zoning System

Different areas of the house may have different temperature requirements as do members living in the residence. What may be hot to one member may be cold to another. Heat has a tendency to rise up which leaves the main floor cool and the floor above it hot. Apart from this, windows located to the south absorb too much sun, making certain rooms unpleasantly hot, while the northerly winds make some rooms feel uncomfortably cool.

Add some of modern day’s most desired features, and the problem gets even worse. Cathedral or vaulted ceilings, large glass expanses, solariums, finished basements, lofts — they all can cause room temperatures to fluctuate dramatically. Expecting a single thermostat to control variations throughout the house is next to impossible. This is the reason why we need something that can regulate room temperature to make it more comfortable.

There's only one way to even out the problem, through system zoning.

What is system zoning?

System zoning is a simple process. It involves fixing several thermostats wired to a control panel that operates a number of dampers in the forced air cooling or heating system. The thermostats continuously read the temperature of their particular zone, then close or open the dampers inside the ductwork as per the thermostat's settings. System zoning is not only helpful for houses that have inconsistent room temperatures, but is also a good option for cooling or heating individual rooms based on the preferred temperature setting.

Why Is it Needed?

Owners will require system zoning in their houses if one or more of the conditions exist:

• There are huge, open areas like lofts or vaulted ceilings, a solarium, or an atrium
• The house has more than one floor
• There are rooms in the attic or basement
• There are rooms with extensive glass areas
• Cooling and heating temperature patterns tend to vary at different hours of the day
• A part of the house has been built on a concrete floor
• The house has wings spreading off the living area

The Benefits:

Energy efficient:

If utilized in a proper manner, system zoning can help save a lot of money on the energy bills. In fact, it is believed that system zoning can save owners approximately 30 percent on a normal cooling and heating bill. These savings can certainly add up to a heavy sum. Also, because seldom-used rooms and guest rooms don't require continuous cooling or heating, system zoning helps save on unnecessary bills by running temperature-controlled air only when it is needed.

Comfort:

Every floor or room in the house has its own temperature needs. The zoning system removes cold and hot spots from every area of the house, making it more comfortable, regardless of its type, design or size.

Most homeowners are unwilling or hesitant of using programmable thermostats because of the initial fee of installation. This is certainly an understandable concern. However, if they focus on the bigger picture, they will realize the long term financial benefits. It is also very important to get the installation done by a professional. There are several providers that offer superior air quality solutions that cater to varying budgets. The best way to find out about such providers is to search online. Most companies have websites displaying their services and products. Home owners can round off to the one that best suits their budget and needs, after getting a quote from at least four providers.

Whether you're building a new house or are updating your house to be more energy-efficient, healthy, and sustainable, using a zoning system will certainly help you achieve this goal.

Finding the right HVAC contractor

A heating, ventilating and air conditioning system is designed to suit our individual needs. However all of us take for granted the comfort provided by our central air conditioners, heat pumps or furnaces until something goes wrong and the unit needs to be serviced or replaced. When disaster strikes, you need a quality heating, ventilating and air conditioning (HVAC) contractor who is knowledgeable, experienced and competent to do the job. Choosing the right HVAC contractor is almost like choosing a life partner because careful consideration is required.

It is very easy to fall victim to unskilled, even unethical contractors trying to make a quick buck from homeowners eager to restore their cooling systems. Hiring an unqualified contractor may result in the need for expensive and unwarranted repairs to fix problems created by them.

What you need is a quality contractor who knows not only to service your equipment but to design and install the right system for you in compliance with the regulatory and local codes of proper business and workers’ compensation insurance. He must be attentive to your problem, survey the area, reliable, fast, and courteous and most importantly must be abreast with the newest technology and developments, equipment and design procedures to ensure that you get not only an efficient system but one that suits your pocket. If you find one that cares for the environment too that’s a bonus you don’t want to miss. He must also recommend a planned preventative maintenance service to maximize the life of your equipment.

Before making calls in different directions, arm yourself with all the relevant information (brand and model number of the current unit, thermostat[s] and past service history. Knowing your home’s current situation gives homeowners a great place to start. Do remember to ask the contractor for references of customers. Better still ask around your family, friends and colleagues for firsthand experience or if they know someone that recently got some HVAC work done. Check if he comes with the required licenses, certifications and is partners with obligatory associations like NATE, North American Technician Excellence, it is the nation’s largest and most prestigious technical certification organization in the heating and cooling industry. Be sure to obtain bids from a few different companies and weigh what you are receiving with each price. Once you have narrowed it down to your top 3-5 choices, set up times for an in-home estimate. Post inspection and deliberation on the alternatives get a written estimate for the job. Don’t feel shy to ask about a guarantee. It must be written and should state clearly what is guaranteed, who is responsible for the guarantee and how long the guarantee is valid. Make final payments only when all work is completed to your satisfaction and pay by check never by cash. It's always a smart idea to purchase the most energy efficient HVAC system solution you can afford, so ask our contractor to run options by you. Leverage technology - review web sites like Yelp and Google but use caution. Check reviews but ascertain its credibility first. Most manufacturers will not allow poor contractors to be displayed on their web site, so that’s a good starting point. It is helpful to know if the company has a policy to show up on time or refund money.

Remember that not all HVAC contractors are created equal! So do not be afraid to be very diligent in asking questions because choosing the right HVAC contractor can mean the difference between an installation that goes smoothly and provides years of trouble-free comfort and one that winds up costing you thousands in wasted money and aggravation.
