If you’re considering replacing or installing your central air conditioner, you’ve probably heard that it’s among the most crucial home improvement that you can undertake in terms of comfort. On a hot, humid summer day, few things can make your life enjoyment more than air cooling.

Air conditioning is among the most costly improvements you can invest in, so it is essential to do your research and choose the best option.

The kinds that are available for Central Air Conditioners

This article is about whole-house cooling and not only rooms with a single unit and heat pumps.

Contrary to portable, single-room window or in-wall air conditioners that are mobile or window-mounted central air conditioners aren’t mobile, window or in-wall air conditioners for single rooms. central air conditioner circulates air throughout the house.

If you’re not sure about whether you should purchase Room air conditioning units or central air conditioners look into the article on Central as well as Room AC which offers a comparison between both. For more details on rooms air conditioners that only serve one room, take a look at How to Buy an air conditioner for a room and window AC.

As shown in this diagram as shown in this diagram, the central cooling system is comprised of the condenser unit, as well as an air handling device that includes a blower (such as an air furnace that is forced) and an Evaporator coil. The ductwork system allows you allows the exchange of air inside the room to chilled air.

The condenser is usually outside, while the air handler as well as the evaporator are usually located in the basement, attic or garage. The ductwork is located in the basement or attic and the walls of the house.

The air conditioner makes use of technology to cool the air. (For more information on how it functions check out how a Central Air Conditioner Works.)

It’s connected to the air conditioner. It’s basically an air conditioner which can be turned off in the winter months to keep a house warm. If you’re looking to learn the details about this, make sure to check for our Heat Pumps buying guide.

A/C Sizing & Cost

If you’ve decided that a the central AC model is your most suitable option for your home is the best time to study the dimensions and kinds of units as well as its energy efficiency, as along with the features, warranties and more. These issues are addressed in the following article. For more assistance, visit:

Central AC Energy Efficiency

Because of the high price of energy, air conditioners are expensive to operate and make more use of than they provide to our energy sources. When choosing the right one it’s essential to keep in mind that the primary purpose of this day’s work is energy efficiency. This is the ability of the air conditioner to convert electricity (electricity) in order to chill efficiently. You’re seeking maximum cooling for the smallest amount of cost.

A note about replacing an old model Take into consideration replacing the condensing units inside your outdoor unit as and an indoor evaporator. If you only replace the condensing unit, then any possible advantages of a system with greater efficiency could be removed.

The SEER Rating

To cut down on energy consumption and lower energy consumption to reduce the waste of energy, U.S. Department of Energy set minimum standards for efficiency for air conditioners.

Every AC unit comes with an efficiency score, which is also known as SEER. It is a form of seasonal efficiency rating. Efficiency Rating.

The SEER rating is found on the Energy Guide(r) label that is put on each unit. It is important to examine the ratings. The greater the score, better the efficiency of your system, and the less it will cost to run cooling.

In the last 10 years, the SEER minimum rating for the latest models has experienced a increasing continuously.

Older air conditioners may have SEERs less than 6 models, models manufactured after January, 2006, must be able to attain an SEER of 13. Models that work best are those with SEER ratings between 15-17. In order to help you understand the extent of the distinction the SEER 13 rating can be 30% more effective than a SEER of 10.

Features to save energy

To get the best SEER scores, ACs could include a number of energy efficient features. Be sure to look for:

Large coils to improve heat transfer

High-temperature ratings (EER) greater than 11.6 with an expander valve to allow thermal applications. In the event that the ambient temperature gets high, it is a sign of high efficiency.

* An air blower that has an adjustable rate to assist in reducing the power consumption by adapting the usage according to the requirements

This is a switch only intended for fan. This allows you to shut off cooling however, the fan will continue in order to circulate air, resulting in an cost-effective natural cooling.

The delay is an automated fan switch that will keep the fan on for long enough to make use of the cool air that remains after the compressor has shut off.

* A warning light on the filter that informs users that their filter needs changing. This boosts efficiency and helps ensure that the filter is maintained properly.

Other Features

Many high-efficiency models include a number of these features. They also include that are unique to them. One example is The York Stellar Ultra includes two compressors which work in tandem when a huge cooling capacity is needed. The majority of the time , just one compressor is operating. When coupled with the variable speed motor, will give you the SEER of 16.7.

Programmable thermostats also assist in giving an accurate control.

What’s the matter with Ultra-High Efficiency?

Do you need an ultra-high-efficiency air conditioner? Not necessarily.

Naturally to protect the environment, from energy consumption to greenhouse gas emissions, the more efficient is the more efficient.

If you’re looking at dollars, your savings in comparison to the price you’re paying might not be suitable for you, particularly for those living in climates that isn’t a lot of cooling all year round, or if the house isn’t sufficiently insulated.

But if the air conditioner needs to operate continuously all through the year, the most efficient model will earn a profit from the amount of energy saved over a period of months.

Central AC Warranties

AC warranties are crucial in making sure you that AC units last for an extended period of time.

Before you buy central AC Dealers in Surat and ask for a warranty and then read the warranty carefully.

The warranty for air conditioners may differ between one brand and the next. A warranty could be extended to all the units with a single set of conditions, or offer distinct coverage for different components of the air conditioner.

For example, Whirlpool covers all parts of the mechanical and refrigeration equipment (except filtering for air) for a period of five years, which includes all labor.

Carrier will provide coverage for the cooling unit as well with authorized labor to repair or replace it for one year. When you purchase Carrier the refrigeration components comprising the compressor, condenser evaporator, connecting tubing , and the charge for refrigeration that includes repairs or replacements are covered for a period of one year and five years years under the extended warranty.

A large number of parts from manufacturers are covered under warranty, however the cost of replacement parts like motors, solenoid relays switches , and fans aren’t covered under warranty.

Another option is available that is called that of the “Limited Lifetime Warranty.” Amana is one example. gives this guarantee and will take charge of the compressor of an air conditioner that has high efficiency, as well as heat pumps for the time that you own the property.

One of the most crucial things to keep in mind regarding the warranty on central air conditioning units is to take the time to read them carefully and know exactly what they do and don’t cover.

It is vital to be aware that a warranty will be null and invalid when the AC is maintained by a technician who isn’t licensed and cannot provide coverage for maintenance routine cleaning, damages, or any other damage that result from not taking care of maintenance.

Understanding AC Refrigerants

Air conditioning systems that contained refrigerants that were used up until recent times could be harmful to the Ozone layer of the earth. Equipment that uses refrigerants that are harmful to the environment is being eliminated worldwide.

If you purchase air conditioner for the first time , make sure that you buy the most recent model with refrigerants that do less harm to the environment.

How do refrigerants react when they flow through AC devices into the air? All refrigerant gasses are stored in the air conditioning system which is sealed. The problem is that a damaged sealed system may cause leaks to allow refrigerant gasses to escape. The release of gases could be a problem in the course of maintenance.

AC Refrigerants Being Phased Out

These were replaced by hydrochlorofluorocarbons (HCFCs). R-22 (also called HCFC-22 or, more often “Freon”) is the most frequently used refrigerant for heat pumps and home air conditioning systems. It’s not as detrimental for the layer of ozone on Earth however it’s still an ozone depleting greenhouse gases. In its manufacture, it produces HFC-23 , which could be a major contributor for global warming.

This is a major issue that is the reason why the manufacturing or importation of R-22 AC apparatus was banned by the EPA in 2010 as a part of the Clean Air Act. The manufacturer of refrigerants R-22 was cut by 75 percent. The company plans to reduce it to 90% in 2015 and will be eliminated by 2020. As a result, R-22 is becoming more expensive.

If you’re looking to get R-22 recharged on your current equipment, you must request an estimate and check whether the quote is for maintenance costs of around $115. Don’t be surprised if fuel is priced at $100 or higher per kilogram. It is possible that this price will increase. (Equipment generally needs to be billed if it’s leaky. The first step is to repair your leak!)

Solutions to R-22 Refrigerant

These days, a variety of companies that manufacture air conditioners and units that are designed for use by homeowners offer AC systems that make use of Ozone-friendly refrigerants. To maintain equipment that is already in use, R-22 is available and will remain in stock for a time that is 10 years or more.

The EPA has examined several alternative options to R-22. They’re listed on this list of alternative options in R-22 on the EPA website.

A well-known alternative to R-22 is R-410A which is a mixture that contains hydrofluorocarbons (HFCs). It is available and manufactured under various trade names, including Puron(r), Forane(r) 410A and the GENETRON AZ-20(r) and SUVA 410A. It’s not a depletion or destruction of the Ozone layer, however, similar to R-22 its manufacturer is able to contribute to global warming. R-407C, a good substitute for R-22 is employed in some European cooling systems used in homes.
