Learning about normal AC noise versus AC noise that signals a problem is important. This knowledge comes in handy for anyone wanting to know what to do if their AC breaks. After all, there are several noises AC systems commonly make that are perfectly normal. Knowing what isn’t normal is key to keeping your AC in good working order and extending its life as long as possible.

There are a few normal sounds that any well-running AC might make. There’s the humming, starting-up sound the AC makes when it first kicks on, for example. There’s also the gentle whirring noise the outdoor condenser unit makes while it runs. The metal ductwork that connects your AC to the vents in your home might also make noises over time. These sounds come from normal expansion and contraction due to temperature changes through the seasons.

Other noises, on the other hand, can mean the AC … Read Full Post »

It’s a big inconvenience when you have a broken AC unit. It could even be a dangerous situation if your AC breaks when it’s very hot or cold outside. That’s why it’s so important to get the problem fixed as quickly as possible. Of course, that requires determining what the problem is, so that it can be properly addressed.

It’s important to note that sometimes, AC units have problems that don’t cause obvious symptoms. The main thing you might notice is a gradual increase in your monthly utility bills. This is because an AC with worn-out or broken components can’t run efficiently. It may keep limping along, using more and more electricity as it struggles to keep up with demands on the system until it finally breaks completely.

Some AC problems are simple enough to figure out and fix on your own. Others are more complex and need fixing by a professional. … Read Full Post »

There are certain sounds your furnace should never make—at least if it’s well-functioning and in good condition. So when you hear your furnace making noise, it’s smart to pay attention. This is especially true if it’s making a strange noise you haven’t heard before.

When furnaces make strange noises, it’s a sign that something within the heating and cooling system is wearing out or broken. These strange noises might include humming, clicking, banging or rattling sounds. Let’s learn more about what it means when your furnace is making noises.

1. Making Banging Noises

If your furnace starts making banging noises, it’s time to contact a heating and cooling specialist to determine what’s going on. Depending on when the noise happens and for how long, it might signal several different problems with your furnace.

If the banging noise happens when you turn on the heat, it could mean the furnace won’t ignite like it’s supposed … Read Full Post »

If you’re shopping for a new AC, you might feel confused by how many different units there are to choose from. One way to narrow down your choices is by looking for a unit with a higher SEER rating. But what is SEER rating? Think of it as an indicator of how efficient your heating and cooling system is—and the more efficient, the better.

If you’ve never heard of SEER ratings before, you aren’t alone. Lots of people aren’t familiar with the term. SEER stands for Seasonal Energy Efficiency Ratio. It’s calculated by dividing an AC unit’s total BTUs of cooling output during a given period of time by its total watt-hours of energy input during the same time period.

Fortunately, you don’t have to do complicated math to understand that a higher SEER rating means better AC unit efficiency. The concept is pretty simple. When your heating and cooling system runs … Read Full Post »
