My AC Line Is Frozen: What Happened?

Have you noticed that your air conditioner doesn’t seem to have the same cooling power it used to? It’s a good idea to give your AC system a once-over as soon as possible to try to identify the problem.

After removing the cover to your AC, do you notice that the lines or other internal components are frozen, or coated in ice? This is a sign that a bigger problem could be happening.

Why do AC Lines Freeze?

Typically, air conditioner lines freeze up when the unit’s evaporator coils get too cold.

The evaporator coil is one of the key parts of your AC system. The coil is full of refrigerant that is pumped through lines from the compressor. It then absorbs the heat from the air it pulls from the room.

The AC fan blows air over the coils, and this air is cooled as it passes over the refrigerant-filled coils, before blowing back … Read Full Post »

If your air conditioner smells when it runs, there is a good chance that something within the system is broken and needs to be fixed. In some cases, it’s actually a sign of a problem that could be making your health worse. There’s also a chance that it’s something simple you can resolve on your own. Either way, it’s important to do some investigation and troubleshooting. The best option is always to have your AC system checked out by a heating and cooling specialist, to make sure everything is working as it should.

Musty or Moldy Smells Coming From the AC

Humidity within the AC system is one of the most common causes of bad smells coming from the AC when it runs. Many people don’t realize that the AC doesn’t just cool the air in your home on a hot day. It also removes humidity. When there’s too much moisture in … Read Full Post »

Do Air Conditioners Dehumidify?

When the temperatures start to rise, we can all be very thankful for the invention of the air conditioner. The cool air pouring from the vents brings the inside temperatures down to a livable level. The cool air pouring from the vents brings the inside temps down to a livable level.

Hot air might make you uncomfortable, but high humidity can trigger breathing issues for people with asthma or other disorders. It also can increase the chances of mold growing in your home, which is a whole other problem. So removing that moisture from your home’s air is important for several reasons. Doesn’t the air conditioner do the job?

The short answer is yes, but there is more to it. An air conditioner does reduce the amount of moisture in your home. However, it does so as a secondary benefit to its main job, which is to cool the temperature of the … Read Full Post »

Why Do My Lights Dim When the AC Turns On?

If the lights dim when the AC turns on in your home, it may not be cause for alarm. Your home’s electrical wiring is a limited circuit, so when one appliance draws a lot of power, it’s taking it away from anything else that you have plugged in. It’s also possible, that the dimming lights are a sign of a problem.

Of everything in your home that uses electricity, your heating and cooling system use by far the most. The AC needs a lot of power when it first turns on. In some homes, especially older ones with dated electrical wiring, the lights dim slightly when the AC turns on because a lot of power is being drawn momentarily. In this case, the lights dimming briefly is normal and doesn’t signal a problem.

However, in other homes, the dimming lights do signal a problem. It could be within the AC system or … Read Full Post »

AC Is Cooling but Not Removing Humidity

No one wants to be uncomfortable in their own home, especially when the air-conditioner seems to be working fine but something feels off. You have probably heard people living in desert climates say “It’s a dry heat.” But it’s still hot, and even worse than being hot in your house is sitting in a humid chill. What could be going on with your AC?

Usually, an air conditioner’s refrigerant draws in excess moisture from the indoor air. That vapor then condenses into water droplets. This drains into a pan under the unit’s evaporator coils and through a hose to your yard. If your AC isn’t pulling in that moisture, the humidity is just hanging around, which makes everything feel stuffy even if you are feeling a cool breeze. There are several reasons that your AC might not be dehumidifying. You can always contact a pro for AC problems, but there are … Read Full Post »

Why Does My AC Drain Line Keep Clogging?

When your AC drain line keeps clogging, it can be frustrating if you don’t know why it’s happening or how to resolve it. Even worse, a clog in the line can lead to even bigger AC problems that require expensive repairs. Fortunately, a clogged condensate drain pipe is a common issue that usually isn’t too complicated to fix. It’s even easier to take some common-sense steps to prevent the line from clogging in the first place.

Here are some signs that your AC drain line is clogged:

  • There is standing water in the drain pan of the AC’s indoor unit.
  • There are damp conditions or water damage near the indoor unit.
  • A moldy, mildew-y or musty smell is coming from the indoor unit or from the AC vents in the house.
  • The AC isn’t working—either it won’t turn on, it shuts off unexpectedly, or it runs but isn’t cooling the home.

One common reason why AC … Read Full Post »

What Size Air Conditioner Do I Need?

If you’re in the market for a new air conditioner, you’re probably wondering, “What size air conditioner do I need?” Obviously, you don’t want to overspend on a system that’s more than you need. But, at the same time, buying a new air conditioner that can’t keep up with your home isn’t money well spent, either.

While brand reviews, warranties and service agreements are all important factors to consider, they are only really helpful once you’ve determined which products are the right size to do the job.

The two most important factors in determining the size of the air conditioner you need are going to be the size of your home and how much of your home you want covered. Cooling a bedroom in a small home or condo is a very different job that maintaining a pleasant temperature in a large house with an open floor plan. You’ll also want to … Read Full Post »

Air Conditioner Not Blowing Cold Air But Running

a home's ac vent

If you find your air conditioner not blowing cold air but running, there is a problem in your AC system that needs to be fixed. The exact problem depends on whether the AC is blowing warm air or no air at all. If there is no air getting through the system, there may be a blockage somewhere or a bad blower motor. If air is getting through but it’s not cold, there is another issue.

Before you try to figure out what’s going on, it’s a good idea to turn off the AC. Letting it run while there’s an undiagnosed issue could lead to bigger problems. That might mean even more complicated and expensive repairs. After turning off the AC, you can do some troubleshooting. Keep in mind that in the majority of cases, the best course of action is to call a professional to diagnose and repair the problem.

Room Temperature Doesn’t Match Thermostat Setting

The summer sun is beating down or winter’s chill arrives, so you set your thermostat to a comfortable temperature. But, your system doesn’t respond. What do you do next?

You could put on a pair of shorts or a parka, depending on the weather, but that doesn’t solve the problem. The best bet would be to contact a professional who knows exactly what to look for. They know how to get things working properly again. Or, you could take a couple of steps yourself first.

You Set the Thermostat Too High or Too Low

Have you set the thermostat a lot higher or lower than the outside temperature? Forcing the HVAC to “hurry up” and heat or cool your home to your desired temperature only makes the unit work harder. This won’t get you to your comfort zone and it isn’t good for the life of the system either.
