Have you ever thought about how many watts an air conditioner uses per hour? Well, that is typically determined by the type of air conditioner and the frequency with which it is used.

However, the AC has a specified power requirement of 2.72 kW for cooling and 2.69 kW for heating. Air conditioners are a must-have for people who live in hotter climates.

It’s a big investment, but it will make their home much more livable, especially in the warmer months. However, the higher your power consumption, the higher your monthly electric bill will be.

That’s why so few homeowners have central air conditioning installed. However, it will be very helpful to know how many watts the air conditioner you plan to buy actually uses. Take the time to read on and gain some knowledge from this piece.

How Air Conditioners Work

Air conditioning is the process of removing heat from an enclosed area and regulating the humidity in the air to make it more bearable to be in.

What Affects How Many Watts an Air Conditioner Uses

  • How Much Does it Cost to Run an Air Conditioner? Although the amount you pay for electricity each month will vary based on the rates in your area, you can get a rough idea by using one of two methods. According to Energy Star, annual heating and cooling costs account for roughly 50% of a typical homeowner’s energy bill, or $1,000. If you live in Florida or another warm state, cooling costs can make up as much as 70 percent of your monthly electric bill during the summer months. That’s a lot of money, so it’s wise to consider energy-saving options.
  • When deciding on an air conditioner, take the size of the room into account rather than the wattage rating. Buying a too-small model is just as bad as going with a too-large one. If you skimp on the size, the system will have to work harder to keep the room at a comfortable temperature. If the unit is too big, it won’t be able to perform at its best. Too much humidity remains in the air after the system has cooled the house. That’s not pleasant, and it could lead to mold issues in the future.

One of Senica Air Conditioning, Inc.’s trained HVAC technicians can look over your current setup and get a feel for your home’s unique requirements. You can then move on to considering energy efficiency and other features once you have determined the appropriate size for your space.

Conserving Energy With an AC

The SEER, or seasonal energy efficiency ratio, measures the effectiveness of air conditioners. For a given amount of work, a higher efficiency rating indicates that the unit was created with efficiency in mind. While window or wall-mounted air conditioners cannot be awarded the Energy Star label, central air conditioners can. Crystal River, Florida has a long warm season, so it’s smart to invest in the most energy-efficient model you can afford if you live there. To get the most out of the money you spent on a good air conditioner, you must maintain it properly. Maintenance should include scheduling annual inspections, changing filters frequently, and keeping the outdoor unit free of debris.

If you want to make sure you don’t forget to schedule routine maintenance — which, as we’ve established, is essential for optimal performance and prolonged service life — but is also easy on the wallet, consider signing up for an annual maintenance agreement. Our licensed HVAC specialists are here to address any concerns you may have regarding watts, running costs, and routine maintenance contracts.

Factors That Affect Your Electric Bill

A/C units can cause your electric bill to skyrocket, so it’s important to think ahead about how that might affect your budget before making a purchase.

Factor #1. Your environment

For this reason alone, most people choose to cool their homes with air conditioning during the summer. People who are subject to high temperatures, particularly during the summer months, will have to spend a lot on their electric bills. The occasional attempt to forego the comfort of air conditioning during periods of extreme heat may be met with resistance, but if doing so will save money, the sacrifice seems worthwhile.

Factor #2. Local electric bill rates

The unit’s price tag isn’t the only thing that could cause a heart attack; the electricity bill you’d have to pay every month could be just as much. You see, every kilowatt-hour (kWh) your air conditioner uses will show up as a line item on your electricity bill.

If you want to save money on your electric bill, it’s important to know when the local rates are high and when they’re low. Energy Star estimates that the annual value of a homeowner’s electric bill is $1,000, with this amount covering the cost of electricity for half a year.

Now picture the electric bill of someone who lives in a warmer state, where the cost of cooling is higher and accounts for as much as 70 percent of the total during the summer. Inconveniences your finances, right? Save money on your utility bills by being resourceful about how you use energy around the house.

Factor #3. The size of your AC unit

The majority of consumers purchase smaller units because they are less expensive, but this practice may be contributing to rising utility costs. Putting a tiny air conditioner in a huge room will waste a lot of energy because it will take longer to cool the entire space.

You shouldn’t buy a larger air conditioner because it will cool the room too quickly, leaving behind moisture that could support mold growth.
