A white and gray kitchen with an ac that won't run

As temperatures start to rise, most people count on having a working air conditioner. Having a fully functional AC system isn’t just a matter of simple comfort; it can actually be a real health issue, especially on the hottest days of summer. When you turn on the AC, you expect it to do its job quickly and efficiently, which is why if your AC won’t run, it’s a big and urgent problem. The cause of the problem might be as simple as a tripped circuit breaker or a blown fuse, but it could be something more complex and potentially costly to repair, such as a bad motor, burned wiring, a broken thermostat or a refrigerant leak.

When you turn on your air conditioner, you expect your home to become a cool and comfortable reprieve from the outdoors. This is why it would come as quite a surprise if you hear your unit shut off quickly after turning on, even though your home isn’t cooling down. After this happens a few times, you’re probably wondering what is going on and what you can do about it.

Before we get into what might be causing this to happen, it’s important to be able to recognize what is considered short cycling and what is considered normal for a typical cooling system. The cycle on a properly-working air conditioner should be roughly 15 to 20 minutes, and your system will run two to three times each hour. In very high temperatures, the cycle will be longer as the AC tries to get the home down to the correct temperature.

Short cycling, in … Read Full Post »

There’s nothing quite like the cool relief our air conditioners bring us on hot summer days.

This is why it can come as quite a shock when you step through your door only to find that your house is warm. After some investigating, you may realize that warm air, and not a cool blast, is blowing out of the vents throughout your home.

Unfortunately, there is no easy answer as to why your unit might start blowing warm air. While some of these issues warrant professional help, there are certain steps some homeowners may feel comfortable doing on their own, especially those who are familiar with how HVAC systems work.

Why Does My Air Conditioner Smell Musty?

When we turn on our air conditioners, we expect our homes to become cool and comfortable. In some unfortunate situations, however, homeowners turn on the AC, only to detect an unpleasant odor. If your air conditioner smells musty, you’re probably trying to get to the bottom of the problem and figure out what you can do to fix it.

The most common culprit of an air conditioner that smells less than fresh is the presence of mold somewhere in the system. The other possibility is that your AC unit’s coils have started to corrode. Either way, your air conditioner has likely experienced a buildup of moisture, and the warning sign that that this may be the case is a bad smell.

Not all musty smells coming from your vents start in your air conditioner, however. Identifying the cause of this problem is the first step to resolving it. There are a couple … Read Full Post »

When you enter your home after spending time outside on a hot day, there’s nothing quite like the gust of cool air coming from your air conditioning vents. That’s why if you find yourself in a situation where you have no cold air coming from your AC, panic can quickly start to set in. Most likely, you switch into high gear, trying to determine what went wrong and what you can do to get your air conditioner working normally again.

There are several things that could be preventing your AC from blowing cold air, including a problem with your thermostat, dirty filters, a clogged condensate line, a blocked compressor or dirty coils. Your air conditioner is a machine with many parts that need to work together. If any one of these parts isn’t working correctly, you wind up with a system that doesn’t cool anything down or maybe doesn’t blow air … Read Full Post »

Water Leaking From AC Unit: Should I Be Worried?

Water leaking from an ac unit

Finding a pool of water near your air conditioner can be alarming. You may ask yourself: Why is this happening? Is this liquid water, or could it be refrigerant? While being in this situation can be alarming, you should know that it’s not uncommon to find moisture near your AC unit, and this may not actually be a bad thing. To determine whether your water leak is serious, it’s helpful to understand how air conditioning systems work.

Air conditioners use refrigerants to cool down the air that flows through your home. These systems operate thanks to a handy piece of physics: When a liquid turns into a gas, it absorbs heat. So, with a substance that changes from a liquid to a gas at a relatively low temperature, as is the case with refrigerants, you can harness that heat-absorption power to cool down a home on a hot summer day.

While this is arguably a better situation than having an air conditioner that won’t turn on, it’s still wasting energy and money. So, what can you do to turn off your air conditioner? Or is this a problem that requires the help of a professional?

Electrical issues are the most common cause of an AC unit that won’t stop running and these types of problems typically need to be addressed by a licensed heating and cooling specialist. However, before contacting a professional, you can check your fan to make sure this isn’t the problem.
