Purchasing an AC Unit For House That Is Energy Efficient

When buying an air conditioner for your house, you want one that is energy efficient. The higher the SEER rating, the more energy it can save. This will save you money in energy costs and lengthen the life span of your unit.

There are four main types of air conditioning: window units (central AC), heat pumps and ductless systems.


The size of your AC unit will have a significant impact on how much energy you consume. Selecting the right unit isn’t something to be rushed through. You need to make sure that the new AC is the correct size for your home. If it’s not the right size will either be too big to cool your home, or won’t work at all. This will cost you money. A qualified HVAC contractor can help you determine the right size unit for your home.

There are several different factors that go into determining the correct size of an AC unit for your home. Some of these are obvious, such as area. Other aspects aren’t as intuitive, such as the amount of technology that generates heat or appliances in your home. These items produce a lot heat that your AC has to deal with.

It is also important to take into consideration the climate of your area, as well as the kind of building materials you’ve used. Certain types of materials reflect and absorb heat differently, which can affect the size of your air conditioning unit. It is also important to consider the degree of insulation your home is and the number and kind of doors and windows. Some of these are designed for letting lots of heat in and might require that you use more of an AC unit.

Affirming all of these variables into account is the only way to make a truly precise decision about the best AC unit for your home. You can utilize a chart of square footage to get a general idea, but the best method to determine the size of AC you require is to have a Manual J load calculation completed by an expert.

When you know the amount, you can choose the model that is suitable. However, you should note that if you have made modifications to your home since the last time you replaced your air conditioner, that you’ll need more power for the new space.

Energy Efficiency

British Thermal Units (BTUs) are used to evaluate air conditioning units. The higher the rating, the more efficient the unit is. On the unit, you’ll find a SEER rating or Seasonal Efficiency Ratio. A lower score means less efficient AC.

The size of your air conditioner is determined largely by the area of your home. There are a variety of other factors to take into consideration. The amount of windows in your home and the orientation of them towards the sun can affect the amount of heat transferred to your home. The insulation level of your home will also affect the quality of your home. Insulation is crucial because it stops cold air from escaping as swiftly.

When selecting an AC unit, it’s important to take into account your family’s lifestyle and habits. If you leave your doors and windows wide open will require AC more than those who close them. You can also look into tax credits for models that use less energy. These discounts can drastically reduce the cost of a new air conditioner. A newer model will also be more efficient than an older model.


When your air conditioner works properly, it will make a light sound that hums when it’s operating. If you hear any other sounds that aren’t, it could be an indication that the unit isn’t functioning properly.

The ringing sound that occurs when your air conditioner is running could be the result of various issues. It is important to get it checked promptly to avoid further damage to your system.

It’s possible that the fan is obstructed in the event that your air conditioner makes an eerie sound when it’s running. This could be caused by debris or dirt that’s stuck within the unit, a damaged blade, or a loose component that could cause the fan to rumble when it turns. It’s important to check the inside of your unit for these types of problems, as they could result in a damaged compressor.

Another common AC issue is when it begins to produce a whining sound when it’s running. It could be because the ducts are not properly sealed. This allows cold air to escape while allowing warm air to be able to. This could be due to cracks and holes in ducts that need to be repaired as soon as possible.

If you hear a sound of hissing coming from your air conditioner, it’s because there is a refrigerant leak. The hissing sound happens when the refrigerant flows from the high pressure side of the system to the lower pressure side, through an instrument for metering that has a small opening. Even though the hissing noise is not a major problem however, it’s an ideal idea to have an HVAC technician look into it just in the event of. It could be costly to fix this problem therefore don’t leave it unattended.


It is essential to maintain your air conditioner, regardless of whether it’s brand new or old. A certified professional will give the unit an general inspection, which can help you spot small problems before they become large ones. They will check the voltage of your unit, check and clean the coils, ductwork and vents, verify the proper refrigerant levels and clean the drain line. They will also lubricate the blower motor and thermostat and replace your filter if needed.

Uneven temperature in the room, inability to start the system, or making loud and squeaky sounds are all indications that the system needs attention. It may also be time to think about replacing the system, particularly in the event that your energy costs have been rising.

A well-maintained AC unit will last much longer than one that is neglected and will save you a lot of money on your energy bills over the years. Making sure you are keeping up with maintenance tasks such as replacing filters frequently as well as washing and wiping the unit outside, and keeping it free of debris will ensure that you enjoy the longest number of years out of your ac unit.

It is important to keep the surrounding area free of obstructions such as leaves, twigs and cobwebs that could restrict airflow. You can also hose down the fins and coils of the outdoor unit to keep it clean. Use a garden hose, not a pressure washer which could cause damage to the components of the unit.

Some AC companies provide maintenance contracts that provide customers with two-yearly maintenance inspections as well as reduced rates on parts and accessories. They are a great choice when you do not have time to maintain your own equipment or if you want peace of mind knowing that a trained technician is watching your system. Additionally, many companies give contract customers priority service whenever a problem occurs. It isn’t necessary to wait long to get an air conditioning emergency repair.
