The Signs and Causes of a Broken AC Unit

a white kitchen

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 »

What Is a HEPA Air Filter?

Studies show that the air inside our homes is often much more polluted than the air outside. That is why many people have started turning to air purifiers to help make the air in their home healthier. However, not all air filtration systems are the same. Some offer a much higher level of protection.

HEPA air purifiers offer one of the highest levels of protection available to homeowners. HEPA stands for “high efficiency particulate air,” and it indicates the product uses a certain type of air filter. For a product to say it is a HEPA air purifier or HEPA air filter, it must meet the standards set by the U.S. Department of Energy.

This means that anything labeled as a HEPA filter must remove at least 99.97% of particles from the air that are just 0.3 microns in diameter. A micron is a unit of measurement used to determine the size … 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.

It’s never a good thing to catch a whiff of a foul smell coming from your home. It’s even worse when you can’t name it or find it. It seems familiar, like gym socks that fell behind the washing machine. But that isn’t quite it. A quick check of the laundry room finds everything in order.

You know when the cat’s litter box needs changing, or if the laundry has been sitting in the hamper too long. A fragrant trash bin is easily identified. Maybe the house just needs a good cleaning? No, even after the kitchen, bathroom and floors get a good scrubbing, the off-putting scent lingers.

Once you have run through the list of usual suspects and still haven’t discovered the source, you might want to zero in on your HVAC system. Your house might have caught a case of dirty sock syndrome!

What Is a SEER Rating?

a living room

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 »

My Heating Won’t Turn Off: What’s Going On?

It’s frustrating when you find that the heating won’t turn off and your furnace is running nonstop. Could it be something simple that you can fix yourself? It’s possible, and it’s always a good idea to check the simplest things first.

Thermostat Setting Is Too High

You might have accidentally set the thermostat to a temperature that’s too high. The heater then has to work overtime to make the house warmer than it needs to be.

Fan Set to On

Or maybe the fan setting on your thermostat was accidentally switched from “Auto” to “On,”. This causes the furnace blower to run constantly. Switching it back to Auto allows the furnace to cycle on and off again as needed to keep your house at the temperature that you set on the thermostat.

It’s important to note that your furnace itself isn’t actually running nonstop when you set the fan to On. Only the blower runs … Read Full Post »

If your AC seems to be cycling on and off more often, running longer, blowing warmer air or in general not working well, it’s time to investigate. The sooner an AC problem is fixed, the better. When an AC stops working, it’s not only uncomfortable and inconvenient; it can be downright dangerous. When your AC malfunctions, you may wonder, “Are the coils frozen on my AC unit?” If you fear you have a frozen evaporator coil on your AC unit, it should be diagnosed quickly to avoid bigger and more costly problems.

By now, you might be wondering, what is an evaporator coil and what does it do? The evaporator coil is the part of the air-conditioning system that absorbs heat from the air inside a house. It is a series of U-shaped tubes filled with refrigerant and connected to the indoor components of the AC system.

Depending on the AC system, … Read Full Post »
