Selecting a Filter For Your Home Heating and Cooling System



Filtering the air in your home may seem just like a quite simple task, however, there’s a lot more to selecting a filter than most homeowners and even some heating and cooling contractors realize.

The science of moving the air through your duct must certainly be considered first. The fan or blower motor provides the job of turning the fan blade. The air in your home is then pulled to the return grills and the return duct system; the air then moves through the heating or cooling equipment per the requirements; and is then pushed through the supply duct and grills back in your home as “reconditioned air”. Every component in this ventilation path provides a measurable level of resistance to the flow of air and you will have to ensure that you pick up the best AC filter for air flow so that all pollutants get filtered out efficiently during this process. These air conditioning components range from the grills, duct, filters, and equipment. The style of the equipment and duct is beyond the control of the homeowner, and if properly created by the contractor, shouldn’t present any problems that the fan cannot overcome.

The filter(s) in the machine, however, is produced a really wide array of materials, sizes, and may have varying locations. To properly explain filter selection, we first must provide parameters for both “ends” of the spectrum. On one end, let’s assume “no filter” at all. This would provide zero resistance to ventilation at the filter location. On the other end, let’s assume something solid, like steel. This would provide total resistance to ventilation at the filter location. Every heating and cooling filter available is somewhere between those two points on the spectrum.

As we select a “tighter” filter, we move nearer to the steel example on the spectrum. We should be conscious of the fact that a tighter filter will reduce the amount of ventilation, and cause the fan motor to work harder. It’s possible, without considering this, that people may cause a decrease in heating or cooling capacity and efficiency by selecting too tight of a filter, or by failing continually to re-design the ventilation system to be able to compensate for the tighter filter. That doesn’t mean we cannot use tighter filters. If the material used is denser, then we could compensate by using a larger filter area. Put simply, if your system works on the 20 x 20 x 1 standard filter that you can easily see-through, and you wish to put in an improved filter best air filter for ac, you may need to put in a bigger size so that the same level of air can pass right through to the blower. Here is where your heating and the cooling contractor might help you decide the easiest way to perform this.

In many cases, the ductwork on the return side of the machine may need to be increased in size to allow for the added resistance of the tighter filter. Sometimes, simply adding additional returns to the prevailing ducts will solve the problem . Your heating and the cooling contractor has approaches to measure this resistance and understands how to resolve the ventilation issues.

In conclusion, simply installing a tighter filter of the same size that you currently use may be causing a more impressive problem. You must consult your heating and cooling professional when it comes to filtration upgrades. If the machine is designed correctly, you can install better filters without stopping comfort and energy efficiency, or damaging your expensive heating and cooling equipment.

Roof Height Safety System: The Right Way To Secure Risks While Working at Heights



Falling from the roof of a building is one of the biggest causes of accidental death worldwide.

There is always a range of roof height safety protocols to make sure that their life is safe. Even for residents and those who like to visit the roof from time to time, there have been reported incidents when a cycle of events had led to a dramatic fall from the roof even when the victim was walking on the roof. However, for construction workers, fall from a roof has been reported as one of the biggest reasons for death in construction sites. For this reason, height safety systems should be installed that allow everyone to access the roof in a safe and controlled manner and reduces all risks of falling in these areas.

Who Needs A Safety System?

Most owners who do not visit the roof often or do not provide access to others are under the idea that they do not require to install roof height safety measures because they do not need them. However, safety systems must be installed by everyone who owns a building or has employed workers performing various tasks at lights. This is of prime importance because many construction and other workers lose their life in working from such raised platforms. Hence, any person responsible for the building must provide proper roof height safety measures so that air conditioning unit workers or cleaners can safely perform the tasks.

How To Stay Safe

For construction workers and other personnel who need to regularly work at elevated areas, it is important to follow some basic safety protocols that will help you save your life in a critical condition. Some of the most well-known and important roof safety tips to keep in mind are as follows:

  • Proper Installation And Placement Are Paramount-It is important to make sure that you are always using your ladder correctly. Your ladder must rest on a solid surface, and a ladder leveler can be used if the roof is extremely uneven. You might also invest in anti-slip teeth that can be used on the base of the ladder, especially if you are working on dirt or grass.
  • Try Not To Work Alone At Heights-It would be best if you always worked with others, especially in risky situations. You must have someone with you when working on a roof to call for backup if something is to happen.
  • Avoid Unfavorable Environmental Conditions-You must never work on a snowy or wet roof. Such incidences make the roof extremely slippery, and even if you are wearing safety boots, it can lead to a horrible accident that has to be always avoided.
  • Keep Your Safety Equipment In Good Condition-Always treat your safety equipment with care and respect. Even if you have been working for your years and have a lot of experience, it is important to always wear the proper roof height safety harnesses and equipment.

Training Required For Using The Safety System

A worker needs to understand that several workplace obligations have to be fulfilled to ensure that they have optimal knowledge for working in a dangerous situation like on a roof. Hence, you might require a true set for the training period that will help you understand the basic safety guidelines and safety awareness that needs to be always followed.


By following the right roof height safety protocols and measures, you can make the most of your job without any accidents. Also, the details discussed above will help you select the proper way to choose the right roof safety system.
