How do I calculate what size air conditioner I need?

Finding the right size air conditioner for your home is important for many reasons. This not only ensures that your home is at the perfect temperature all summer long, but it can also save money on your utility bills. Before you invest in a new air conditioner, or call for Denver air conditioner repair, read up on some of the best tips for calculating what size AC unit you need for your home.

Why choosing the right size AC matters

Choosing the wrong size air conditioner can negatively impact your home (and your bank account!). An AC unit that’s too big often results in more upkeep than you have time for and can cost a lot upfront. Smaller units may save your wallet from the get-go, but they’ll do a poor job of cooling your space and cost you more in energy efficiency. A unit that’s not sized correctly to your home won’t run at the capacity that it’s supposed to, causing excess breakdowns and maintenance issues in the long-term. This is why it’s so important to size an AC unit correctly.

How to calculate size

Calculating an air conditioning unit’s size is rather easy once you know the equation. To find the perfect size air conditioner for your home, you’ll need to find the overall BTU needed. Per professional sizing guides, air conditioners require around 20 to 25 BTU of cooling capacity per each square foot of living space.

First, find the square footage of your home. Square footage is found by multiplying the overall length and width of an area. For example, if the room or area is 12 feet wide by 15 feet long, 12 x 15 = 180 sq. ft. Then, multiply the square footage by 25 BTU (the recommended cooling capacity per square foot) to find the overall BTU cooling capacity needed. For this sized space, that would be an air conditioner with a BTU of 4500.

Although this number may seem high, experts recommend 20 to 25 BTU per square foot so that AC units continue to function at high-efficiency no matter fluctuating temperatures or levels of humidity.

What is a good seer rating for an air conditioner?

Shopping for a new air conditioner can be overwhelming. These units not only have a wide array of specs to peruse, but choosing the wrong type can leave you either overspending or uncomfortable during those summer heatwaves.

One important number to keep in mind when shopping for a new Denver air conditioning unit is the SEER rating. Find out more about what a SEER rating is, why it’s important that you choose a good SEER rating, and where to find the best Denver heating and air assistance.

SEER Rating Explained

SEER is an acronym, though you may see two different phrases for it. Both Seasonal Energy Efficiency Ratio and Rating are correct when referencing SEER. The rating is important because it measures the cooling efficiency of an AC unit. According to the U.S. Energy Information Administration, air conditioning units are one of the highest energy spenders in your home. So, paying attention to the SEER number can help keep energy costs low – if you know what to look for.

You can calculate a SEER rating by dividing the total electric energy output by the cooling capacity ratio. If a unit has a high SEER rating, this indicates that it has higher energy efficiency. Each SEER rating can be ranked from most to least effective in terms of efficiency, as well. The average SEER ratings for any given air conditioning unit include:

  • Low-ranking: units with a 13 or 14 SEER are considered the least effective and energy efficient nationwide
  • Average: the most average SEER ratings are between 15 and 20
  • Above-average: units with SEER above 21 are considered the most energy efficient. Some high-efficiency AC units rank as high as 23

Finding the right SEER rating for your home

Having a unit with a high SEER rating doesn’t always mean that it will perform at maximum capacity, however. Like homes, air conditioning units are all different, and most are not designed with a one-size-fits-all approach. HVAC systems are constantly evolving, however, and new technology updates have shown improvements with energy-efficiency, consistency, and cost.

Before you look into air conditioning replacement, be sure to consider your home’s size, as well as your budget. Although a higher SEER rating may impact the upfront cost of your AC unit, it will eventually save you more on your utility bills.

Other energy-efficient tips

SEER isn’t the only determining factor for energy usage when it comes to air conditioning units. There are many other ways you can limit excess energy usage to cut down on utility bills. You can utilize a free, online energy-usage calculator provided by the U.S. Department of Energy. This not only helps calculate energy costs for your home, but will help you determine which units are the best in terms of SEER ratings per your location.

Regular maintenance and upkeep for your current HVAC unit can also help prevent it from using excess energy each month. Check with your local heating and air conditioning professional on how you can use less power or get a home energy audit.

How to Test Air Conditioner Efficiency

Air conditioners are a household essential. Find out how well yours works.

Your home’s air conditioner is a valuable tool. Chances are that you can’t imagine your home without it. When the warm summer air comes rolling in, you might find yourself wondering how well your air conditioner works. Is it an efficient system—or is there something that you can do to make it more efficient? Let’s explore this in more detail.

Testing Air Conditioner Efficiency

The efficiency of your air conditioner really comes down to how well it works. Air conditioner efficiency can change depending on our systems, our homes, and our personal choices. There are many factors at play here, so we will discuss a few of the more common ones.

Consider Areas Where You’re Losing Cold Air

The first consideration when determining the efficiency of your system comes down to the efficiency of your home. Factors like your windows and level of insulation can play a huge role here. Do you have windows that leak cold air? Is there a large gap under your door? How old is your home’s insulation? Consider these factors to determine the overall efficiency.

Keep a Clean Air Filter

Your filter can tell you a lot about the efficiency of your system. If your filter is filthy and clogged, your system’s efficiency will automatically drop. Be sure to look at just how clean your filter is—and clean or replace it if necessary. A dirty filter is an indicator of an inefficient system.

Clean Your Vents

Your home’s vents are another feature that can influence how efficient your system is. If you notice that your vents all look dirty and messy, you will know that your system isn’t efficient. When you see a lot of debris clogging up your vents, it is time to call in a team to get them cleaned so that cold air can easily be distributed throughout the home.

Look at How Cold Your Home is

The general temperature of your home can tell you how efficient your system is. When you feel like your home isn’t getting as cold as it used to, or if your home seems like it is hardly cooler than the outside air, this can tell you a lot about its efficiency. A home that isn’t getting cold like it should needs some work. It might be your system, or it might mean you need to make some of these other changes.

The Takeaway

An efficient air conditioner is one that will be able to effortlessly cool your home in summer—but there is more at play here than just the system. For the help with heating and air conditioning Denver residents need, we are here to help. You can have an efficient system that will keep your home cool all summer long—and during those hot fall days too!

What Causes an AC Compressor to Stop Working

Your AC compressor is an important part of your system—find out what can break it.

Your AC compressor is a valuable part of your air conditioner. Without it, the system truly cannot run. For this reason, there are times when you will find yourself looking to get your AC compressor back on track—but this means being able to find out what is wrong with it. In this article, we are going to explore a few reasons why your AC compressor might stop working.

Disrupting an AC Compressor

AC compressors are very important. In many cases, they will begin to fade before they will outright quit—but that isn’t always the case. Knowing how to spot the signs, like a system that blows warm air or visibly seems to be malfunctioning, can be helpful. Of course, in order to fix it, you have to be able to spot the problem. Let’s explore a few of the more common disruptions.

Problems with the Lines

Your air conditioning compressor has quite a few lines in it—and these lines can lead you right to trouble. Suction lines, in particular, are a point of concern. When they become blocked with debris, you will find that the AC compressor may outright fail. However, with some systems, the problem comes down to the lines being the wrong size to support AC efforts.

Electrical Issues

Electricity runs the modern world, and your air conditioning compressor is no different. If your system is experiencing electrical problems, you will find that your AC compressor is also going to struggle. This can lead to it failing in the long run.

A Lack of Lubricant

Lubrication plays a vital role in most mechanical systems. You will find that this is also the case with your AC compressor. If you don’t have the right amount of oil lubricant, you might just run into trouble. Worse, a lack of lubricant can damage any system and force you to need replacement parts.

Dirt or Contaminants

Nothing breaks a machine down quite like dirt or contaminants. When your system is dirty, it will always be less efficient. Over time, this lack of efficiency can turn into an outright failure. With any system, you always want to keep everything clean in order to keep it running smoothly. If you’re not sure how to do this, it is always a good idea to call in the professionals.

The Takeaway

When your AC compressor goes out, you might want to handle it yourself—but it’s okay if you don’t want to. We offer dedicated Denver air conditioner repair to restore your system and make sure that it is working exactly how it should. While we work, we always look for other signs of future problems, and we are happy to help with any of your needs. To get your air conditioner back online, contact us today to get started!

Why is my AC suddenly not cooling?

As record heat waves arrive this summer, it’s essential that your AC unit is properly cooling your home. There could be a number of reasons why your AC is suddenly not cooling. Read on to discover the top reasons that impact AC cooling and where to find a quick turnaround for Denver air conditioner repair.

Top 5 AC Cooling Issues

The air filter needs to be cleaned or replaced. A dirty air filter is one of the biggest reasons why your AC unit might suddenly stop cooling. Air filters help keep dust, dirt, and other debris from entering into the system. When they get too clogged, however, this blocks the pathway of air inside the ducts. AC air filters should be cleaned regularly in order to keep your unit working at full capacity. 

You need to adjust the settings. Sometimes AC unit fans can blow warmer air if they are programmed on the wrong settings. Try setting your window AC unit to “AUTO” mode so that the fan only turns on to pump cool air. You can also contact your local Denver air conditioner professional to ensure your home AC unit is on the right setting for your home size. 

The outside unit is blocked with debris. AC units located outside the home can often stop cooling correctly if blocked or damaged by tree branches, leaves, or other debris. Be sure that the AC condenser is not clogged, as this can impact how the unit transforms hot air into cool air for your home. Getting your outside AC unit maintenanced regularly ensures that it’s always cooling properly. 

There is an issue with the motor. Although older units are more susceptible to motor breakdowns, newer units can also experience sudden issues due to extreme temperatures. A faulty or broken motor fan will cause the unit to either blow out hot air – or stop working altogether. Fixing an AC motor is best left to a professional, however. Contact a Denver heating and cooling company for guidance on this issue.

The refrigerant fluid is leaking. AC refrigerant helps absorb heat and turn it into the cool air that pumps into your home. A lack of this fluid is a sure sign that your AC unit will suddenly stop cooling. Check around the unit for leaking refrigerant, a buildup of ice around the unit may be present. Be sure to listen for uncommon noises like hissing or gurgling.

Finding AC repair in Denver

If you’ve checked all of these issues and you are unsure what next steps to take to fix your air conditioning unit, consider the help of a professional. Having a functioning AC unit in extreme temperatures is important for keeping cool and comfortable. Professional technicians at Go Green Heating and Air Conditioning can help fix your AC right away when it stops cooling.
