How to Keep Your Central Air Conditioning System at Top Efficiency

central air conditioning system

Due to the rising costs of energy, it is very important that you ensure you buy central air conditioning system and heating models that consume less energy. It does not matter whether you use oil or gas the overall cost may be very high. We cannot stop using the cooling and heating systems in our homes due to the varying climatic and weather changes. This article offers a number of great tips that will ensure you reduce the energy consumption in your home.

The first tip is to ensure that if you are using any central air conditioning system, then there is proper airflow in your home. If you have dirty air filters they may block the airways making the machinery use more energy.  Always inspect the conditioners filters occasionally and replace those that need replacing. This will enable you to spend less in terms of energy costs every year.

The second tip is ensuring frequent inspection of your evaporator and condenser coils. If you lack the professional know-how of doing this you can seek the services of a professional. This will enable you to know whether or not your evaporator is blocked or not. Normally a blocked evaporator forces the system to consume more energy and thus raises the monthly costs. You also need to understand that if your evaporator is blocked the system will wear out faster. To avoid this you always have to ensure that your coil is clean. You may keep them clean using a low-pressure hose so as not to damage the coil given its fragile nature. You can keep the evaporator coil clean using soap and warm water. But great care needs to be taken when cleaning the coil so as to avoid damaging the fins. An old toothbrush may come in handy when cleaning inside the coil.

Another useful tip is the proper maintenance of your product. There are a number of things that affect the temperatures in your home. Good examples are fallen insulation and crumbled or damaged duct lines. Whenever you detect any of these problems it is highly advisable that you contact the service company to have them repaired or replaced. It is advisable that you contract an expert in duct repair and installation to inspect your system every month.

Lastly, the best decision you can ever make that will help you in lowering your monthly energy costs is by purchasing a service agreement from a service company. This will ensure that an expert inspects your system twice a year and makes all the necessary repairs. The expert will also offer many tips on simple maintenance tasks. The company you choose should be able to offer the best services. You can compare the overall cost and the features of different agreements.

AC Buying Guide

Obviously, the main reason to get an air conditioner is to keep your home colder when it is warm outside. But air conditioning is really a complex system of controlling the air temperature, humidity and cleanliness, as well as the movement of air in conditioned spaces. This short guide was created to help you understand the basics of how air conditioners work and to help you choose the right air conditioner for you. We do not sell any air conditioners ourselves, so you can be assured that all of the information in this guide is independent and unbiased.

In this Guide:

1. Background on Air Conditioners

2. Features and functions to look for in Air Conditioners

3. How to find the Best Air Conditioner for you

1. Background on air conditioners

Did you know that in reality, an air conditioner is really making your home ‘less warm’? A simple description of the process is that when air gets cycled through the air conditioner system, heat from the air is absorbed by the air conditioner, and the cooler air is blown back into the room and/or throughout the house. Since this guide is not for engineers, we will skip the technical discussion of how this happens; curious minds can find out easily enough elsewhere.

2. Features and functions to look for in air conditioners

Air conditioners come in many shapes and sizes, but there are really two main types of air conditioners (swamp coolers and other air cooling methods not included). Air conditioners are either self-contained and designed for single or multi-room use, or they are designed to cool the entire house in conjunction with the furnace and ductwork system. The most important feature of any air conditioning unit is measured in cooling capacity.

Cooling capacity is measured in BTUs or British Thermal Units. This figure represents the amount of heat required to lower or raise the temperature of 1 pound of water 1 degree Fahrenheit. The heat that is extracted from your home by an air conditioner is measured in BTUs.

Single or multi-room air conditioners
These air conditioners are designed to work in smaller spaces, such as one room or one level of a home. They can be the perfect solution in a variety of situations: you want to keep the baby’s nursery room cool, one room in the house gets particularly warm, you live in a ranch and only need one level cool, etc., etc. Single or multi-room units are also known as ‘window A/C units’ because they are installed in windows to allow the movement of air from the inside to the outside of the home. These air conditioners come in different capacities, usually somewhere between 5,000 and 30,000 BTUs.

Whole-house air conditioners
These air conditioners are designed to work in conjunction with your home’s furnace/heating system to cool your home. Typically, a unit is placed outside the home and additional equipment is installed in your furnace. This is so the cooler air can be blown throughout the home via the existing ductwork that is directly connected to the furnace. Additionally, the air conditioning system will have to be connected to the thermostat or other control devices to give you some way of controlling the settings on the air conditioner system. Whole-house air conditioning systems typically come in capacities of 18,000 to 60,000 BTUs.

Air conditioners are electric devices, and there are standards in place to determine how efficient the air conditioners use electricity to power their functions. This is known as the SEER (Seasonal Energy Efficiency Ratio), and the higher the number, the more efficient the unit is. The government sets minimum efficiency standards as to the lowest SEER levels allowed.

Where to buy
Most of the whole-house air conditioning systems are sold nationwide through companies and independent dealers and the larger home improvement stores. They will provide installation as well. Many of these dealers have excellent web sites that can give you all the information you need and even schedule appointments for estimates and installation. The single and multi-room air conditioning units can be found at major hardware stores and require minimal installation.

3. How to find the best air conditioner for you

Researching online is the best place to start when shopping for an air conditioner. You may or may not be sure which type of air conditioner would be best for your situation, so doing research on specific models will help you narrow down your choices by price and capacity. Many air conditioners can be financed, either directly with the manufacturer/dealer, or sometimes with large retail chains (usually by opening up a store credit card.)

The most important component to consider when looking for an air conditioner is capacity. Unlike other appliances in the home, it IS possible to get ‘too much power’! A unit that is too large is not only more expensive to purchase and operate, but it also won’t work as well. If an air conditioner has too much capacity for your home, the air will cool quickly, but this could be counter-productive. This is because the moisture is removed as the air is pulled across the cooling coil in the unit. If an oversized unit cools the air too quickly, the unit shuts back down and there isn’t enough time for the moisture to be removed from the air and the inside will remain humid. On the other hand, choosing a unit that is too small is bad because it may not be able to do the job on some of the hottest days. It would be possible to run the unit all day long but never achieve your desired cooling temperature.

Many of the top air conditioning manufacturers recommend that you do not leave the decision of capacity to chance or guesswork. As each home is different in terms of its ductwork, heating patterns, and layout, they recommend that you have an experienced professional determine the proper capacity air conditioner.

Beyond capacity, you should consider the efficiency of a unit because this can help save you money over the life of the air conditioner unit. Don’t be fooled by marketing terms like ‘high efficiency’, though. The one and only number to compare efficiency is the SEER number, and the higher the better.

Make sure to compare warranties among competing brands carefully. Do they include the same components, or is there a significant difference in coverage. Are any labor costs included in the warranty?

If humidity is a problem in your area, find out what (if any) additional accessories need to be installed to control humidity.

Air conditioners are controlled by thermostats, which simply measure the temperature of the air and either turn on or turn off the air conditioner once the ambient air temperature has reached a certain level. You may have the option of getting a programmable thermostat, which gives you the ability to program various ambient temperatures based on time of day or day of the week. For example, if no one was at your home during the day on weekdays, you could program the temperature to be a little bit higher, then have the air conditioner cool the house back down to your desired temp for when you get home. Some systems even incorporate humidity controls into your system. Programmable thermostats can save you operating costs because the system is on less often.

Air conditioning units that have more than one speed are generally more efficient than single-speed units because they don’t have to use more energy than needed.


Some air conditioners are noisier than others, and if this is a concern for you, make sure to hear the unit in action before settling on one model.

Finding a dealer or model
OK, you’ve done your research, you’ve found what you think is the type of air conditioner that you want, know the features that are important to you, what range of capacity you’ll need and what price range you’re probably in. What next?

To find the specific model or dealer, it might pay to ask your friends and colleagues if they have had any experience with dealers or if they like or dislike their own air conditioning system. Instead of or in conjunction with personal referrals, you can find out if any of the air conditioner manufacturers, dealers or models have earned the endorsement of any legitimate, third-party rating entity. Finally, you may consider the brand name as a criterion. Generally, the best-known and most successful businesses are those that do a good job, earn a good reputation and earn repeat business.
