Why Does AC Consume More Electricity Than Other Home Accessories?

An air conditioner uses a lot of electricity, but a loss of efficiency can result in high electric bills. There are many reasons why your air conditioner will cause high electric bills, including dirty filters, duct leaks, malfunctioning parts (motors, capacitors, etc.), low refrigerant, inadequate maintenance, an old system, and poor installation.

1. Dirty Air Filter

Air filters help keep your home’s air handler, ducting, and indoor coil clean. Over time, debris will accumulate if filters are not routinely replaced. This can end up blocking the flow of air through ducts and impair your system’s ability to cool your home efficiently. Longer run times will mean higher electric bills due to overheated motors and compressors. We suggest using replaceable disposable filters which should be changed every 30 days for optimum airflow; this is one of the simplest ways to ensure that your unit does not cause excessive electricity use.

2. Leaks on Duct

Air is distributed throughout your home by your ductwork, which contributes significantly to the efficiency of your air conditioning system. The ability of your system to distribute air and satisfy your thermostat is reduced by a duct leak. The longer your unit takes to satisfy your thermostat, the higher your electric bill will be. If it takes too long to satisfy your thermostat, it will run harder and longer. To fix this problem, we recommend having a duct seal (we use Aeroseal) done.

3. The Lifespan of Running Parts

Inadequate parts in your system like motors, capacitors and the compressor can lead to high power bills. Such failing components reduce efficiency and impede performance, resulting in extra strain on the system. For instance, when the condenser motor is unresponsive and the thermostat is not satisfied, it needs to work harder and for longer; thus causing an increase in energy costs. This may continue until the motor fails entirely leading to a breakdown of air conditioning.

4. Low Refrigerant

In air conditioners and heat pumps, refrigerant (r-22 Freon or r-410a Puron) is used to transfer and remove heat. The system will have to work harder to satisfy the thermostat if it has low refrigerant. If your units are running low then your bills will increase. In most cases, low refrigerant is caused by a leak. Leaks can occur throughout the coils and line sets that transfer refrigerant through the system. To determine if there is a leak, where it is occurring, and what needs to be done to fix it accurately, professional service is needed.

5. Lack of Maintenance

An HVAC expert can maintain your home’s air conditioning system efficiency and prevent possible breakdowns. Furthermore, the technician has all the tools necessary to determine the condition and performance of your system and its components, which can prevent high electric bills.

In addition to cleaning the coil, replacing a capacitor or motor, installing a surge protector, a hard start kit, and sealing the ducts, the technician may recommend installing a programmable thermostat as well.

6. Old System

It is likely that your air conditioner isn’t very efficient if it is old. The highest SEER rating back then was only 10, and with years of working under the hot Arizona sun without maintenance, air conditioners can become expensive to run. Some units are so old and under-maintained that they rust out.

7. Wrong Installation

Last but not least, it could be that the unit was not properly installed. There is a possibility that the contractor oversized the unit, causing it to short cycle and turn on and off rapidly, resulting in high electric bills. Air conditioners use the most energy at start-up which is why they are more efficient when they are less frequent.

There are also problems caused by bad initials such as missing parts, bad electrical connections, bad brazing and welding, and duct connections that are not sealed. In addition to high electric bills, a bad installation can lead to many frustrating breakdowns.

Tips for Reducing Electricity Consumption on AC

There are simple ways to not have a high utility bill even when using an AC

1. Right Installation

If your air conditioner is installed incorrectly, it will work harder, reducing its efficiency and durability, and increasing your energy bill. If you get a local handyman to do the installation, chances are, he may not do it right. Incorrect installation can also void your warranty.  We recommend that you install your AC  only by an authorised service professional if you want it to perform flawlessly for a long time.

2. Proper Insulation of Room

In addition to ensuring the AC outdoor unit is not placed in direct sunlight for an extended period of time, you should also make sure that the room where the AC is installed does not have a lot of windows and doors that allow sunlight to penetrate, making it hotter. As a result, your air conditioner’s performance load increases, which reduces its efficiency. Make sure all windows and doors are closed. If they are not, warm air from outside will enter the cooling area, thereby increasing your utility bills.

3. Non-Stop Usage

Using an air conditioner 24/7 will put a lot of strain on the entire unit as well as its components. Turn off your AC unit when you are not present or after the room has cooled down enough. This will allow the unit to take a break and prepare it to operate efficiently the next time you turn it on. Besides reducing your energy bill, it will also give your unit a break.

4. Regular Maintenance

Ensure that your AC manufacturer provides service and maintenance when you buy it. As with any machine, your AC needs to be serviced regularly as well. During service, all components are checked and dust or dirt is removed from coils. If oil or lubrication problems arise, they are also addressed. During servicing, all tasks help reduce energy costs.

5. Maintain a Constant Temperature

During summer, temperatures can be very high, usually up to 40°C in the early or late summer. Setting your thermostat for temperatures under 18°C puts a lot of strain on your air conditioner. In order to feel comfortable and cool, you need to set your thermostat between 20-25°C. Therefore, setting a temperature lower than necessary is not necessary. Keeping the temperature between 20 and 25 degrees Celsius will prevent the AC from working overtime and save you money.

6. Choose the Right Energy Efficient Star-Rated AC

In order to help customers understand the efficiency of an Air Conditioner, BEE (Bureau of Energy Efficiency) provides a Star rating. A 5 Star Air Conditioner cools a room in the most efficient manner compared to a 1 or 2-star air conditioner. The highest star rating for Air Conditioners is 5, and the lowest star rating is 1. Simply put, a 5 Star AC cools a room faster, while using less electricity than a 1 Star or 2 Star Air Conditioner.
