Watch Out for Air Conditioner Capacitor Problems!

Monday, August 31st, 2015

In our last post, we discussed some issues your air conditioning system might face at the close of the summer. It’s always a smart idea to see to any repairs your air conditioner may need right away, even as the weather begins to cool off. You may still need the AC to work for you in September, and the earlier you have any fixes done, the less expensive they are likely to be.

A Few Air Conditioning Problems to Watch for at the End of the Summer

Monday, August 24th, 2015

Summer is coming to an end, although we can still expect some lingering heat through the early autumn. The air conditioning system in your home has probably spent most of this last season working hard, and all that stress and wear could possibly cause the system to break down. During these final weeks of hot weather, make sure that you pay close attention to some of the warning signs that your AC is having trouble. (And don’t wait to have any problems fixed in the spring! The sooner repairs are done, the less expensive they will be.)

Warning: Your Air Conditioning System Is Not a Dedicated Dehumidifier

Monday, August 17th, 2015

High humidity is a major problem with staying cool during the summer. Especially during the late summer. The high levels of moisture in the air make it harder for your body to release heat through sweating, and that trapped heat makes the hot temperatures feel even hotter. There isn’t much you can about this when you’re outside… but you can change it inside your home.

Signs You May Need to Replace Your Water Heater

Monday, August 10th, 2015

Modern water heater manufacturers construct their products to last. But of course they cannot make them invincible: no mechanical device can endure forever, and wear and tear will eventually lead to the need to replace it. The water heater that delivers hot water to the taps and appliances in your home—from showerheads to washing machines—will at some point need a professional to remove it and put a new system in its place.

How Air Conditioning Refrigerant Leaks Start

Monday, August 3rd, 2015

Among the many different problems that can occur in an air conditioning system, one of the most common (and serious) is a leak along the refrigerant lines that allows the liquid/gaseous refrigerant to escape. Refrigerant, sometimes known as “Freon,” is essential for an AC to work, and if the level should ever drop, the system will not only start to work poorly, it could suffer from a catastrophic breakdown. When refrigerant leaks happen, you need to call on professionals who will 1) locate the leaks, 2) seal them, and 3) recharge the refrigerant to its proper level.

What did I do wrong that caused these leaks?

Don’t worry: you almost certainly aren’t at fault for refrigerant leaks. The unfortunate part of this problem is that it is difficult to prevent and almost impossible, even for professionals, to notice before it starts. You must simply be vigilant about your AC’s performance and call on repair technicians immediately. Regular maintenance will also catch any leaks when they are still small.

Now, as to what causes the leaks in the first place: formaldehyde. You are probably unaware of it, but this chemical is a common pollutant in residential air, and even with excellent air purifiers it is hard to remove it entirely. Formaldehyde causes something known as formicary corrosion along copper lines, such as those in an AC, as it leaves formic acid along the surface. Although copper is resistant to most forms of corrosion, formicary corrosion is an exception. It’s almost impossible to notice along copper surfaces until it weakens the metal to the point the leaks occur.

Any AC over four years old is susceptible to this kind of corrosion, and high-efficiency air conditioners are more likely to suffer from it  because they have narrower refrigerant coils to help with heat exchange. Make sure that you have quality air conditioning technicians to help you in Winnetka, IL in case your air conditioner encounters refrigerant leaks.
