Do Air Conditioners Dehumidify?


In short, yes. Air conditioners do dehumidify the area they are cooling. But how do they remove the humidity? And how much humidity is actually removed by your air conditioner?

These are important questions for those of us who live in naturally humid locations. For example, in the Southern and Coastal states humidity is a constant attribute of the environment all year long. And I personally don’t like it, but that’s another story!

So, experiencing high humidity levels in our homes and businesses can be something that we deal with in these humid locations. The problem with this is that when humidity levels are high inside, it makes it seem hotter than it really is. Think “heat index”. It has the same effect as it does with the outside “heat index”. This can cause us to run our air conditioners at a lower temperature simply because the humidity makes it feel hotter than it really is. This leads to higher energy bills and more money spent. High levels of moisture can also increase the chance of mold and mildew, along with other issues.

So, removing the humidity from our indoor environment is important, as you can see. Now, let’s get into some important questions to answer as we move forward.

r22 refrigerant that is being phased out in a green bottle on a wooden table

R22 Phase Out – Say Bye Bye to Freon


If you haven’t heard about the R22 Phase Out, then this post is for you. This is a very important topic, especially for those who own heating and air units that use R22 refrigerant, typically referred to as Freon. R22 Freon will no longer be available, and will actually be illegal, on January 1, 2020. For this reason, there are important things homeowners and business owners need to know concerning this matter.

We’re going to go over the details of the R22 phase out, why it’s happening, and what it means for you (and me).

What is the R22 Phase Out?

Over 30 years ago the Montreal Protocol was put into affect to cease the production of ozone layer depleting substances. It’s a international agreement to rid the Earth of these substances. It was determined that R22 refrigerant was one of these substances. They stated that Freon was contributing to the depletion of our ozone layer. Chlorine is believed to be the main compound in the refrigerant that causes the most harm to the ozone layer.

thermostat setting for summer with blue screen and black numbers and letters

Best Thermostat Setting for Summer?


Is there a perfect temperature to set your thermostat at for the Summer in order to save energy and still be comfortable? Well, yes, but it varies for each homeowner or business owner. There are recommendations out there by respected organizations that we will discuss in this post, along with some helpful formulas. After reading this post, you will have a better idea of what temperature you should set your thermostat at for the savings you desire.

Let’s get started!

In our last post, we discussed how turning off your air conditioner when you’re away does actually save energy. We also pointed out that turning up the thermostat 7-10 degrees (at least) is the better option when away, in our opinion. But, we didn’t really go over the preferred thermostat setting for Summer months in order to experience true energy (and money) savings.

Well, that’s what we’re going to focus on here.

So, What is the Best Temperature to Set Your Thermostat at for Summer?

turn ac off when hot home

Turn AC Off When Not Home: Good Idea?


A common thought and practice by many homeowners is that it’s a good idea to turn the AC off when not at home. After all, if you aren’t home, what’s the point of keeping it cool and comfortable? This does seem to make sense initially and seems like it would save money on the energy bill.

The Department of Energy says that 48% the average American household’s energy consumption is related to their air conditioning system. That’s a lot!

So, let’s look at all of the factors and truly come to a conclusion on the idea of turning our ac system’s off while we are away and if it actually saves us money.

Is It More Efficient to Leave Air Conditioning On?

Turning off the air conditioner for ANY part of the day in the South can feel like a death sentence! This is especially true in the Summer months, which can seem to last for about 8-9 months out of the year.

closing vents in unused rooms

Closing Vents in Unused Rooms: Good Idea?


I didn’t grow up around HVAC professionals, nor was I one of them. As a child, I remember a common practice was people closing air vents in unused rooms to save money on their electric bill (or gas bill). This always seemed to make sense to me from a common sense perspective. But, does closing off the vents in unused rooms actually help save energy and money? Can closing the vents actually cause problems with the HVAC unit?

In this post I will be answering these questions along with other related questions!

Let’s get to the first question….

Does Closing Vents in Unused Rooms Save Money?

In short, no. Closing air vents in unused rooms actually does not save energy or money. Yes, by closing a vent, air is no longer distributed to that specific area, but that’s likely not what your installed system was designed to do.

What is an Air Handler? What Does it Do?


When it comes to air conditioners and HVAC units in general, there are terms that we hear that we might not have a firm grasp on what they actually are. I want to change that!

For example, have you ever heard of a condenser unit, an evaporator coil, or an air handler? Chances are that you have heard of some of these terms when it comes to heating and air systems. But, do you know what they are and what they do? I’ve covered both what a condenser unit is and what an evaporator coil is in previous posts. In this post I want to go over what an air handler is and the role it plays in the heating and air system.

Air Handler vs Furnace

First off, we need to differentiate between an air handler and a furnace. A typical split unit system consists of an outdoor unit (the condenser unit) and an indoor unit (the air handler or furnace).

What is an AC Evaporator Coil?


In a typical air conditioning system there are primarily two main parts or sections. These sections are usually referred to as the ac condensing unit and the ac evaporator coil. In a previous post we went over the details of what an ac condenser unit is. In this post I am going to go into the details of what an ac evaporator coil is, what it does, where it’s located, and some tips on properly maintaining it.

So, What is an AC Evaporator Coil?

You have probably seen the standard air conditioning systems of today. Normally there will be an outside unit that can be heard kicking on when it begins the air conditioning process. This outside unit is referred to as the condenser unit. There is usually also an indoor unit. This unit is referred to as the evaporator or evaporator coil.

What is an AC Condenser Unit?


Have you ever heard the term “ac condenser unit” or just “the condenser unit” when it comes to an air conditioner? You probably have. And you’ve probably wondered which part of the air conditioner system the condenser unit is. In this post I’m going to share this information with you and much more!

Get ready to learn what the ac condenser unit is, how it works, and how much it costs.

First Off, What is an AC Condenser Unit?

To make it simple, the ac unit’s condenser is typically the outdoor section of the ac unit. This will also be true for a heat pump system as well. The condenser section of the ac unit is made up of the ac compressor, ac condenser fan and the ac condenser coil. All of these components are located in the outside section of the air conditioner. Other components, such as the evaporator coil or air handler, will be located with the indoor section of the system.

Let’s get into how the ac condenser actually works and does it’s job.

home ac compressor is bad

How to Tell if Home AC Compressor is Bad


Nobody wants to have to face a bad home ac compressor, but it does happen. In this post I’m going to share some signs and symptoms of a bad ac compressor along with some maintenance tips to help prevent the ac compressor from going bad. Replacing an ac compressor is one of the most expensive ac repair jobs out there, so properly maintaining this component is important. If the ac compressor is indeed bad, you will want to decide if you should replace the ac compressor or the whole unit.

First off, let’s get into some of the signs to tell if your home ac compressor is bad.

Symptom #1: Air Conditioner Keeps Tripping the Circuit Breaker

If your air conditioner keeps tripping the circuit breaker, then it might be due to the compressor. When compressors get old and start to go bad they can have a hard time starting. This can result in the compressor drawing more electricity than the circuit breaker limit and it “trips” as a safety precaution. If this is happening consistently do not keep resetting the circuit breaker. Simply contact a HVAC technician to come out and assess the problem.

Replace AC Compressor or Whole Unit?


Replacing an ac compressor can be fairly expensive. It’s one of the most expensive repairs in the air conditioning world. That’s why the Replace AC Compressor or the Whole Unit debate is such a common question. Sometimes, replacing the whole ac unit is the better option.

Think about it.

Let’s say that you have a big car repair that has to get done for the car to operate properly. A transmission for example. Let’s say that repair is going to cost $1,500 – $2,000. The car is old, has high miles, and is only worth around $3,000 – $4,000 (with a working transmission). Would it be wise to consider buying a newer car, with lower miles and the less likely chance to have any major repairs spring up? I think most people would say yes.

But, what if it’s a newer car that is still under warranty? Then the likely response would be to use the warranty to have the repair performed.
