5 Reasons Your AC Is On The Blink

5 Reasons Your Central Air System Really Blows

Extreme weather is a fact of life. It happens. You expect your central air and central heat systems to be working at peak efficiency, keeping your family comfortable. After all, it’s a good quality system and it is fairly new. But overall you are dissatisfied with the performance of your system, and this may be why. A federal study published in 2015 by the National Institute of Standards stated that a typical central air conditioning system installed in the United States operates at 65% or less of its rated capacity from the moment it is installed.

Most people think that buying a central air conditioner is like buying a oven or a dishwasher.
This is simply not true. With those types of appliances, the equipment is a black box. It is a self-contained unit, fabricated in a factory that has a consistent environment, with highly control standards. They make it, you buy it, bring it home, install it and it just works. I am a phone buff and I look at it from this prospective, you may want Google to make your smart AC and Heating system, because they design technology ripe for customization. And these systems need customization according to the environment, elevation, climate, and these factors are important to account for when you’re choosing an AC and Heating system. You would want Apple to design your smart oven and smart dish washer because there is little need for customization, you probably just want a big oven or a small oven.

AC and heating installation required a lot of components. And these must be carefully selected for optimal performance. You can customize your AC System kind of like the computer your kid built for a school project. As with computers the sky is the limit. You can buy an Internet enabled game console and it just works, and you can play games on your home network, it is all plug-and-play. On the other hand installing any air conditioning filter you find at the store will not allow your AC system to operate at peak efficiency.

HVAC Components

AC systems are customized and put together in your home by a contractor. Your system is made up of many components that all must work together for peak efficiency. AC systems typically have an airflow system (ducts), a condenser, an air handler or furnace, an evaporator coil, your filter, and so much more. All of these must be properly selected for your specific home and climate, then installed correctly in order for your new super duper high-efficiency AC equipment to properly work to cool your home and achieve the performance and efficiency that you paid for and expect. Because your system is custom built in your home, there are actually five major reasons why you may not get the expected HVAC performance from your system.

Air Conditioning fixes

I just had a contractor perform a tune up, and he said all components are in good working order, but I am still not satisfied. Now what?
There are four common problems with central air systems, it is too big (that’s what she said), the refrigerant is overcharged, the fan speed is off, and a poorly designed airflow system.

The system is not properly sized for your home – This doesn’t always mean the system is too small. A system that is off-the-charts huge is a serious problem, too.
The refrigerant is not properly charged – Charging the equipment to 90% or 110% will cause efficiency to drop 20% or more. Charging the refrigerant is a tricky matter and AC installers typically prefer to pull a number out of their posterior and save time, which can cost you thousands.
Fan speed wasn’t set correctly – Most systems come from the factory with the fan set to its fastest setting. The fan must be adjusted to match the needs of the other components installed, otherwise the system may be straining to move far too much air for optimal performance. Check on this if your system is making a lot of noise and using more electricity than needed. When the air moves through your system too quickly, the moisture, or humidity, may not be dissipated as effectively as it could be with slower moving air.
Airflow systems (returns, registers, ducts,) are not sufficient for the needs of the home – The duct system must be designed and laid out with attention to detail, there is no margin for error. The ducts needs to be optimized for the airflow needs of the home and the AC components. If the ducts (returns and registers) are not properly designed and installed, your central air equipment can be damaged and your system can not perform properly, leaving you paying more for electricity than you should and enduring an uncomfortable home.
Air Duct Leakage – Several years back, Austin Energy found that most duct systems need to be resealed, and those systems lose more than 25% of their air to leakage. With duct leakage, you are getting hot or cold attic air into the system (rather than conditioned air from your home) or you’re throwing money away sending the air you just paid to cool or heat up through the attic or outside your home.

In conclusion, there are many issues that can lead to poor HVAC efficiency. In most cases, it’s not one culprit that causes the system to act up, rather it is a combination of factors. The experts at Service Pros will work with you to diagnose performance issues. Call us (325) 455-0894
