HEPA Filters: Why They Matter

hepa filterOne cannot deny the fact that HEPA filters matter. The acronym stands for high efficiency particulate air filter. The HEPA filter is primarily used for several different reasons like the control of microbes and allergens in laboratories and hospitals, manufacturing and production facilities, and even private homes.

There are filters and there are HEPA filters. In order for one to be classified as HEPA, it has to be able to meet specific guidelines laid out by the United States Department of Energy. Of all the specific guidelines, the most notable or basic one is that the filter should be able to remove ninety nine percent of all contaminants from the air. Those contaminants are at least 0.3 microns in diameter.

For information sake, a micron means a millionth of a meter. To have a clearer look at how small it really is, a human hair is about a hundred microns wide while a tobacco smoke particle is between 0.01 and 1.0 micron. Meanwhile, most bacteria particles are within the 0.35 to 10 micron range. Any substance or particle that is smaller than 10 microns will be invisible to the naked eye. Hence, something that is 0.3 microns is considerable small. But then again, a HEPA filter can still capture bacteria or particle of that specific size. That’s why such kind filter matters.

The usual HEPA filter is made up of mat-like material reinforced with fibers. The fibers have to be arranged in precise order so that the small particles will stick to them in three possible ways namely interception, impaction, and diffusion. Interception is actually the first line of defense that is usually utilized in a heating and cooling system. It is in interception where most particles in the air flow stream commonly stick to the fiber. Impaction on the other hand is the second line of defense where larger particles will be trapped in the curved-designed contours of the fibers. Finally, diffusion is the last line of defense. It works by trapping the molecules that are just too small for both impaction and interception through forcing them to bump with gas molecules.

The use of a HEPA filter nowadays is primarily noticed in situations and scenarios where sufficient and ideal indoor air quality is needed. A sufficient indoor air quality may be needed in manufacturing industries and commercial spaces, but today it is also very much a necessity in private homes and living spaces. It means that the lack of good indoor air quality will affect the health of the people living inside the home and will most likely cause or result to allergies, asthma, and other kinds of respiratory illnesses.

In the end, appliances and home equipments that use HEPA filters matter a lot and even play a major role in making sure the indoor air quality is at its best state to ensure the health of everyone living inside. With HEPA filters, there is a greater chance of avoiding and preventing skin and eye irritations, breathing issues, and nasal stuffiness, all caused by contaminants and allergens present in the air.

Carbon County HVAC Tips: Indoor Air Conditioning Components

AC componentsWhat are the various indoor air conditioning components? Read on and we will provide you with a comprehensive list of some of the most important components you ought to know and their functions:

1 – Condensate System

Condensate, or simply water, is produced by the system when warm moist air is cooled. The process is done by blowing it over the evaporator coil. The condensate then runs down the coil into the collecting pan, and then it drains to the piping that is used to route condensate to the drain for disposal.

2 – Condensate Pump

Condensate pumps are intended for systems that are not capable of disposing the condensate through the simple law on gravity to the drain line.

3 – Condensate Overflow Pan/Tray

This refers to the container that is situated below the air handler. It is found in a unit that is located or placed in an attic or in instances where the overflow of the condensate will spill into the building floor or the ceiling. It is actually classified as a safety device designed to prevent the occurrence of spillage. To function properly, it has to have an independent drain or a float switch for shutting down the indoor air conditioner in the event that the pans become full.

4 – Blower Fan

The blower fan is also called the evaporator fan. It is located in the blower compartment and is responsible for circulating the building or indoor air into itself from the return ducts and plenum. In the process, it moves the air across the evaporator coil to the supply plenum and then to the supply ducts in the building. There are several types of blower fans and they are single speed, multiple speeds, and variable speed. There are also blowers that are intended for continuous operation.

5 – Electrical Controls

The electrical controls of an air conditioning include several components. First, you have the shut-off switch or a series of switches, fuse and circuit breaker, capacitor, and others.

6 – Evaporator Coil

The evaporator coil meanwhile is also called as the cooling coil. It is connected to the high pressure and low pressure refrigerant lines. The high pressure refrigerant liquid is released into the cooling or evaporator coil through the thermal expansion valve. It is then converted from liquid to gas. As a result, there is a drop in the temperature of the refrigerant, in the process cooling the evaporator coil.

7 – Air Filters

The air filters are situated on the return duct air inlets or the one or more of the central return air inlets, or even in the air handler unit. They are primarily used to remove and filter dust and debris from the indoor air, to make sure the same air is clean.

8 – Thermostat

The thermostat of the indoor air conditioner plays a major role since it is utilized to turn the AC on and off. It is also the same component that is toggled for setting the desired temperature indoors.

How a New Thermostat Can Improve Your Air Conditioning System

thermostatYour thermostat at home is something that you always see every day but you actually don’t pay too much attention to it. But you do have to understand that it is one of the most important components of your air conditioner and heating system.

The thermostat is that small and handy little device that plays the major role of controlling the heating as well as the air conditioning system in your home – two of the biggest energy-consuming equipment you are in need of. Without heating and air conditioning, you don’t feel the kind of comfort and quality you deserve in your living space.

But in today’s trend of energy consumption and the continuous rise in energy prices, you will be forced to hand out some attention as to how your thermostat works. You see, it’s just like any other appliance, equipment, or device you use – it won’t function well if it is already too worn out, deteriorated, or damaged. Therefore, there will always come a time that you need to have a new one.

A crucial part of your air conditioning system maintenance is the replacement of an old thermostat. At this point, you are most likely going to ask why. Obviously, the main reason is to improve the performance of your system. But we do care about giving you the specifics. So here it is:

Better and Improved Efficiency – One of the greatest benefits of digital thermostats is that they offer you precise control as to the kind of temperature you want for your home while at the same time giving you digital displays that are easier to read. But if you go for programmable varieties for your thermostat replacement, what you get is more than just total control and advanced display. With a new digital programmable thermostat, you are able to set different times of the day or week as to when you exactly want your air conditioning system to operate and turn on. Hence, you are in a way directing your system to operate efficiently, specifically when you’re in the house. In turn, it turns off when you’re not around.

Increased Comfort – A new thermostat also improves your air conditioner by way of being able to provide more comfort to you. How is that possible? It’s actually quite simple – most of the cooling problems you experience with your air conditioning system is due or caused by wrong thermostat installation or fault calibration. For instance, it may be installed in an area where it gets direct sunlight, which means it can detect the wrong temperature due to the heat of the sun. Hence, if you have a new thermostat installed, you also get increased comfort in the process.

Avoid Constant Repairs – Finally, when you decide to have a new thermostat, you prevent the likelihood of always having to call in the AC repair technicians. Most of those repair needs can simply be caused by bad thermostats.
