Why Indoor Air Quality is Essential For Good Health

Ask many people about air quality problems, and they will check out the outdoors. Nevertheless, the Environmental Protection Agency (EPA) called indoor air pollution one of the United States’ top environmental health issues and has also recognized the call to improve indoor air quality.

The quality of air features a direct impact on the health, comfort, and concentration levels of every person. Poor indoor air quality might be the reason for most people falling ill. Consequently, indoor air quality testing is a good investment in the health of your family and safety of your property.

Who Is Affected By Poor Indoor Air Quality?

The air pollutants set stress on your immune system, in which can bring about other medical problems. The results of poor indoor air quality on an individual can vary significantly based on age and relative health. Nevertheless, in general, poor indoor air quality leads to allergy symptoms, respiratory problems, and weakened immune systems. Youngsters are especially prone to the health risks of polluted indoor air since their lungs are smaller and they’ve got to take more breaths throughout the day. If you experience allergy symptoms or asthma attacks in your home, you may have poor indoor air quality.

There are many factors affecting the quality of indoor air. This can include uneven temperatures, poor ventilation and air circulation, mold and fungi, a high level of pollutants as well as other suspended particulate contaminants. Hence, fresh air, adequate sunlight, good ventilation systems, and controlled humidity could dramatically bring about a healthy working environment at any workplace. Oftentimes, odor control can also be an important aspect of maintaining the high quality of indoor air.

How Can Quality Be Improved?

To raise the quality of the air, you will want to set up high quality air filters in your house. High quality air conditioner filters are created to trap air pollutants as the air goes through the filter material, effectively getting rid of these pollutants from the indoor air. This greatly minimizes exposure to airborne contaminants and will prevent allergic reactions, asthma attacks, as well as other respiratory problems linked to poor air quality in the home.

You may also Improve your ventilation by opening windows when it’s possible to, turning on the fans at home to circulate air and purchasing a home air purifier. Make sure you keep ventilation running in areas that are constantly wet, just like your bathroom. Get rid of the unwanted chemical pollutants at home. Going green appears to be a trend, but it is a healthy one. There are a wealth of green cleaning supplies available online or at your local supermarket or convenience mart.

 

5 Benefits of HVAC Duct Cleaning

 

It’s easy to disregard the air ducts at your residence. In fact, you cannot see them. But these hidden systems are a really crucial section of your house. Just like other areas of your property, they might occasionally have to be cleaned. Duct cleaning have several benefits.

1. Duct cleaning can improve your health. Air duct cleaning is crucial to healthy and clean indoor air. Allergens (pollen, pet dander, hair, etc.), debris and dust and toxins (mold, mildew, mouse droppings, etc.) are consistently found in home HVAC systems. If a person residing in your home already suffers from allergies or asthma, air duct cleaning can help provide a healthy environment for asthma and allergy sufferers. Typical cleaning has been confirmed to reduce the quantity of allergens and pollutants present in your home, ultimately decreasing the possibilities for allergies as well as other certain illness.

2. Duct cleaning will help your HVAC system last longer. It’s estimated that 90% of heating and air conditioning systems breakdown or fail because of a insufficient proper maintenance. Expenses for repairing heating or cooling system is frequently quite expensive and total replacement of your HVAC systems may cost thousands of dollars.

3. Duct cleaning offers energy savings .The Environmental Protection Agency (EPA) estimates that by cleaning as little as four-tenths of one inch of accumulated dust (slightly under ½ inch) out of your heating/cooling system coils could lower energy usage by up to 21%. Think about saving 21% of your next heating or cooling bill!

4. HVAC functions at an optimum performance. If the unit is dirty from the inside, its components, such as net, filter and exhausts are covered in dust. This decreases the unit and there’s a reduction in the efficiency of the system. Once the system gets slow, it signifies that the unit is working hard to deliver less. As long as the servicing and cleaning of the system is carried out frequently, it’s going to work at its optimum efficiency.

5. Duct cleaning could keep your home smelling fresh. Have you noticed a moldy odor in your house? Unclean air ducts could possibly be the reason. A professional cleaner could inspect your house, as well as your air ducts, and allow you to know if HVAC cleaning could help reduce the odor and help your house be a more pleasant spot for your family.

 

How to Hire an HVAC Expert

 When hiring for an HVAC expert there are things we need to consider before hiring them. We don’t simply just hire but we also need to be responsible to avoid more damage. This article posted below are some of the tips that helped before that I would also like to share with you all.

The heating and cooling system is one of the most complex systems that can be found in a home. It’s essential that the HVAC service provider you hire is well-trained to deal with the inherent safety issues in heating systems — electricity, natural gas, oil — or cooling units that use toxic refrigerants such as Freon.

A few decades ago, before home air conditioning, the job was simply known as ”furnace repair,” and even ductwork was an afterthought since heat rose naturally and air flow was only marginally understood. Today, ventilation has become a technology of its own.

An HVAC contractor will play a crucial role in your home’s comfort, air quality and safety. Consider these steps when making your hiring decision.

HVAC Contractor Requirements

Many states that license HVAC contractors require that the applicant have a minimum amount of on-the-job or training experience — typically 2 to 5 years — working with HVAC systems.

That experience is critical since an HVAC contractor will need to have a competent understanding of how things like electrical wiring, refrigerant, combustion systems, and airflow through heating ducts all work together to add heating or cooling comfort to a home.

Boiler Maintenance and Repairs Tips

For those who have a boiler, you must discover how to look after it to be able to get the very best service. Regular maintenance will assist to make sure that you do not have to keep repairing the unit. How you take care of your system determines just how long it’s going to last and how effective it’ll be. You can avoid the costly repairs by following quick and easy tips.

Unfortunately, lots of people do put their boilers’ maintenance out of their minds until there’s a problem. Without a doubt, it really is appealing to do so, as boilers are difficult, and several problems encountered by users do require specialist. Understanding the distinction between work that can be done by the average operator and that which requires a specialist can save you from a realm of expensive and time-consuming repairs.

Regular Maintenance

When you buy the boiler, it arrives with a user manual. This manual come in very handy when you really need to make emergency boiler repair. Familiarizing yourself with the system will help you to know how to troubleshoot the equipment if it has a problem. Should you have misplaced your manual, contact the manufacturer for a replacement. In most cases, you can download the manual straight from the manufacturer’s website.

Regular maintenance starts off with initial start-up. This is the most important step impacting the boiler. Boiler start-up must be done by the manufacturer’s authorized agency. Inspect all gauges, controls, water glass, and blow-down piping, relief valves and others. Also check for foreign objects on both fireside and waterside. Check interiors for rags, scrap material and tools. Run electrical equipment to check the operation and ensure lubrication to rotating parts. Fill with water and boil promptly to drive off dissolved gases in order to avoid corrosion.

Resetting your Boiler

As outlined above, the majority of boilers have several emergency shut-off safeguards. When one of these shut-offs is triggered, restarting your boiler is a straightforward matter, but you need to bear in mind that the shut-off was triggered for a reason.

Possible causes of emergency shut-off include low water level, excessively high or low gas/water pressure, as well as other conditions that make it dangerous for the burner to function. Keep in mind that a few boilers also have shut-off devices tied to time clocks and outdoor temperature, thus a shut-off doesn’t necessarily show a problem.

Modern boilers have emergency shut off systems which will shut the boiler down if you experience a problem. Additionally they shut the boiler down if they are tied to clocks and outdoor temperature therefore it doesn’t always mean you have a issue. A few of the explanations why a boiler uses the emergency shut-off may be simple things like low water pressure.

 

 

An Energy Efficient Home

Have you ever envisioned your life without power? What is going to happen to devices and home appliance then? Most people are aware that energy is one of our basic essentials. Nevertheless, energy is really a fast reducing resource and we all must take each possible measure to sustain it. One of the simplest ways to do so is to make your home more energy-efficient. Sometimes people have the tendency to waste a lot of energy being that they are not fully conscious of our ecological situation. They don’t know that within their simple acts, a major progress can occur.. Becoming more energy-efficient isn’t only constrained in your own home, you can also utilize it in your workplace or some other places you’re going. Below are great tips how

Conduct an energy consumption assessment

A home energy audit is usually the first step in making the house more energy-efficient. An audit will help you examine the amount of energy the house utilizes and assess what steps which can be done to be able to improve energy-efficiency in the home. Through this process you’ll find what particular system at home is not working economically. Yet, should you be interested in getting specific tips for boosting the efficiency of your home, consider getting in contact with an expert Home Energy Auditor..

Seal the leaks

Air sealing is the process of sealing leaks in a building envelope to restrict the amount of air that escapes out of and into the house. The air leaks through your envelope just like the outer walls, windows, doors, along with other openings. Consequently there’s a squander of a lot of energy and so grows your utility costs. A well-sealed envelope can create a real difference on the utility bills and energy utilization.

Try insulation

To explain simply what insulation means, it’s simply basically your barrier between your house and the outdoors. Heat flows naturally from a warmer to a cooler place. In summer time, heat goes from outdoors to the house interior while during winter the high temperature moves directly from all heated areas towards the outside. Insulating roofs, wall structure, and floors lower the heating or cooling essential to offering an efficient resistance to the flow of heat.

Whilst making use of air conditioners or heaters, remember to opt for temperatures that make you feel comfortable rather than selecting an intensive climate. For example, when you’re utilizing an air conditioning unit, there’s no sense in keeping icy cold temperatures and wearing sweaters even if you are inside.

You’ll find simple tricks that can be effortlessly implemented in your daily routine in making your home more energy efficient in a relatively shorter period of time.

 

Home Insulation Guide

Insulation helps make one’s house more comfortable by helping to keep a consistent temperature in the home. Walls, floors and ceilings tend to remain comparatively warmer during the cold months and much cooler in the summertime. A great home insulation system helps in avoiding environmental damage a result of air conditioners and heaters that emit greenhouse gases.

In choosing insulation, keep in mind that the greater the R value, the better it is at saving energy and helping make your home comfy. You can choose from a number of insulation types, according to your requirements and what you would like to pay. One of the benefits associated with having chosen the correct material would be a home that is correctly insulated and efficient with regards to heat and consumption. There are 4 different types of insulation you must know about if thinking of your house;

Fiberglass Insulation
You’ll usually find the fiberglass type placed between wall studs and roofing joists. It is composed of synthetic fiber with fine strands of glass kept together in a sheet or mat by a minimal amount of resin coating. It is lightweight and does not wear out its functionality progressively. Although it is pretty versatile, it is found to be not as safe for use. If you’re planning on adding this on your own, make sure to wear gloves, a safe mask/glasses and a fully sleeved shirt.

Loose-Fill Insulation
Loose-Fill is either blown or added into a section of a property, often put to use in enclosed spaces for example attics, ceilings, walls and floors. Loose-Fill insulation is available in a number of materials just like fiberglass, rock wool and cellulose.

Spray Foam Installation
The spray foam insulation is comprised of a type of foaming agent plus a polymer one. In most cases sprayed into tiny cracks or spaces. These kinds of insulation are great for the areas that do not have a regular shape. When it’s applied it comes in liquid form, however in a short period of time it turns into a solid mass.

Rigid Foam Insulation
Rigid foam home insulation, also called foam boards are more widely used to insulate the foundation of a home due to their water resistance abilities. Another popular use of this type of insulation is for exterior insulation on walls or under siding. They should be fit tightly together in order to avoid any loss of energy. It has a higher R-value than fiberglass, which is the reason many householders and builders opt to use it.

 

How to Choose the Air Purifier For Your Needs

Running an air purifier may be one of the smartest decisions that one could make for the comfort and safety of your own house. It’s going to assist you with removing all contaminates from your home that may trigger allergies and even asthma in you or your loved ones. Odors is treatable if you choose the right model of purifier and you may also work at removing the presence of bacteria, fungi, and infections in the air.

Well, here are the factors to consider when choosing an air purifier.

1. HEPA Filter Standard Air Purification. By definition, a HEPA filter removes at least 99.97% of all particles as small as 0.3 microns.

2. The size of the room and the capacity of the air purifier system. Unless the two are compatible the efficiency will be largely reduced.

3. The noise created by the air purification system.

Here are a few tips given by experts in air purification systems:

• Identify your needs. Examine aspects like size of room, air currents, human traffic, and use.
• Review the different selections in air purifying systems before choosing one. Systems with HEPA filters eliminate particulate matter while electrostatic systems clean air using charged plates. Others introduce ozone into rooms while yet others have got activated carbon that eliminates odors.
• Find out the area coverage of the purifier. Make sure the square footage listed for the air purifier is about the same or a bit greater than the square footage of the room in which you intend to use it.
• Go through the features and the corresponding price. Immediately after narrowing your budget range down a bit, think about not only the initial price, but also the long-term operational cost.
• Look into the CADR rating: Clean Air Delivery Rate (CADR) is a rating in which lets you know how effective an air purifier is in getting rid of dust mites, pollen particles, and smoke out of your indoor air.
• Most air purification systems have regular maintenance requirements. Thus determine about servicing the filters and changing them. Go through suggestions of the manufacturer.

It will also be smart to constantly compare as there are several models and brands of air purifier prior to purchasing one. This will give you the best indication of all of the various forms of technology which are available and help you identify what exactly you may want for your house.

Visit the internet and go to websites that gives fair air purifier ratings and reviews that will help you make an informed decision. Make use of the valuable tips and information given on the World Wide Web to buy the most suitable air purification system to suit your needs.

 

 

Should You Have the Air Ducts in Your Home Cleaned?

Proper maintenance is key to ensuring heating and cooling systems work efficiently. Here are some tips on maintaining the home’s system, including important information about duct cleaning.

 

 Should you have air ducts in your home

Duct cleaning has never been shown to actually prevent health problems. Neither do studies conclusively demonstrate that particle (e.g., dust) levels in homes increase because of dirty air ducts. This is because much of the dirt in air ducts adheres to duct surfaces and does not necessarily enter the living space. It is important to keep in mind that dirty air ducts are only one of many possible sources of particles that are present in homes. Pollutants that enter the home both from outdoors and indoor activities such as cooking, cleaning, smoking, or just moving around can cause greater exposure to contaminants than dirty air ducts. Moreover, there is no evidence that a light amount of household dust or other particulate matter in air ducts poses any risk to your health.

You should consider having the air ducts in your home cleaned if:

checkmark

There is substantial visible mold growth inside hard surface (e.g., sheet metal) ducts or on other components of your heating and cooling system. There are several important points to understand concerning mold detection in heating and cooling systems:

  • Many sections of your heating and cooling system may not be accessible for a visible inspection, so ask the service provider to show you any mold they say exists.
  • You should be aware that although a substance may look like mold, a positive determination of whether it is mold or not can be made only by an expert and may require laboratory analysis for final confirmation. For about $50, some microbiology laboratories can tell you whether a sample sent to them on a clear strip of sticky household tape is mold or simply a substance that resembles it.
  • If you have insulated air ducts and the insulation gets wet or moldy it cannot be effectively cleaned and should be removed and replaced.
  • If the conditions causing the mold growth in the first place are not corrected, mold growth will recur.
checkmark

Ducts are infested with vermin, e.g. (rodents or insects).

checkmark

Ducts are clogged with excessive amounts of dust and debris and/or particles are actually released into the home from your supply registers.

If any of the conditions identified above exists, it usually suggests one or more underlying causes. Prior to any cleaning, retrofitting, or replacing of your ducts, the cause or causes must be corrected or else the problem will likely recur.

Some research suggests that cleaning heating and cooling system components (e.g., cooling coils, fans and heat exchangers) may improve the efficiency of your system, resulting in a longer operating life, as well as some energy and maintenance cost savings. However, little evidence exists that cleaning only the ducts will improve the efficiency of the system.

You may consider having your air ducts cleaned simply because it seems logical that air ducts will get dirty over time and should be occasionally cleaned. Provided that the cleaning is done properly, no evidence suggests that such cleaning would be detrimental. EPA does not recommend that the air ducts be cleaned routinely, but only as needed. EPA does, however, recommend that if you have a fuel burning furnace, stove or fireplace, they be inspected for proper functioning and serviced before each heating season to protect against carbon monoxide poisoning.

If you do decide to have your air ducts cleaned, take the same consumer precautions you normally would in assessing the service provider’s competence and reliability.

Air duct cleaning service providers may tell you that they need to apply chemical biocide to the inside of your ducts as a means to kill bacteria (germs) and fungi (mold) and prevent future biological growth. They may also propose the application of a “sealant” to prevent dust and dirt particles from being released into the air or to seal air leaks. You should fully understand the pros and cons of permitting application of chemical biocides or sealants. While the targeted use of chemical biocides and sealants may be appropriate under specific …

A Guide to Understanding HVAC Filter Maintenance

“The air filter units play a vital role of improving air quality where they trap dust particles and allergens thus preventing them from gaining access into the house. For the units to continue working efficiently you need to take good care of them.”

 

Proper HVAC filtration is at the heart of indoor air quality and provides an important service in keeping indoor environments clean and free from the dust and particulates that may reduce product yields or create other risks. Filters will only do their job and perform as specified, however, when they are maintained correctly.

Proper filter maintenance is crucial to keeping HVAC ductwork clean. If dirt accumulates in the ductwork, and if the relative humidity reaches the dew point (so that condensation occurs), then bacteria and mold may grow. This is especially the case in HVAC systems with acoustical duct liners, which are frequently used in air handler fan housings and supply ducts to reduce sound transmission and provide thermal insulation.

For all of these reasons and more, it is crucial to establish the appropriate filter change-out frequency. However, filters should be changed immediately if they become wet, microbial growth on the filter media is visible, or when filters collapse or become damaged to the extent that air bypasses the media.

FILTER INSTALLATION

After specifying a filter media and selecting a filter, it’s important to pay close attention to proper filter installation. The goal is to avoid bypass air, which causes contamination in housings, coils, fans, and ducts. Do this by making sure that all the air in the system goes through the filter. To avoid problems later on, consider these installation tips:

  • Check for filter media damage such as rips or holes and replace damaged filters.
  • Make sure media is sealed in the frame to avoid bypass air.
  • Install the filter according to the airflow direction indicated on the frame.
  • Ensure that the filter fasteners are in place and correctly installed, especially if filters are serviced from the downstream side.
  • Check to ensure that the bank of filter frames is rigid and well reinforced to avoid collapse.
  • Caulk any cracks between filter frames or …

Top 5 Significance of Biomass Boilers

“Since conventional energy supplying approaches are escalating in price and people have become more aware of the effect they have on the environment, alternative methods have become ever more popular as they are more eco-friendly and reasonable. A very common alternative is biomass boilers. Biomass is used mostly as the fuel however some of the systems may use biomass with a fossil fuel as a back-up for fulfilling peak demands. Biomass systems are a less expensive system for heating and even electrical power. In comparison with those utilizing fossil fuels, biomass boilers bring about lower carbon dioxide emissions.”

Biomass heating systems have become very popular as a sustainable form of heating and this is largely a result of annual increases in energy prices depending on fossil fuels which commonly utilizes wood pellets.

Usage of organic products.

The types of materials utilized to fuel the biomass boiler are organic rather than fossil fuels which can eventually run out. There are numerous alternatives in relation to the types of fuel you may use for a biomass boiler, some of which include wood chip or sawdust or even municipal solid waste, which could reduce the amount present in landfills. Despite the fact that larger amount are essential than previous it’s still far more affordable to gain power in this way.

Versatile in kind.

This kind of heating system can be used for any objective, whether for steam production, water production or area heating in structures. Biomass is made use of primarily as the fuel even though some of the systems may utilize biomass with a fossil fuel as a back-up for fulfilling peak demands. These can be utilized in almost any scale, whether in district, industrial, domestic or slightly commercial heating.

Much cheaper source of heating.

You can be less exposed to increases in energy prices. At this time, global energy prices are unstable and sometimes subject to political crisis. Issues in a few gas and oil regions mean that the energy market may be unstable and price rises inevitable. Budgeting for energy costs in this erratic market can be hard from one year to the next, with the expectation that energy prices will always increase. Biomass fuel costs less than fossil fuel and is sustainable long-term providing a program is put in place to handle woodland and resources.

Lower CO2 emissions.

You are going to decrease your carbon footprint. Biomass fuels do release carbon into the environment but only a portion in comparison to fossil fuels. It is calculated that the annual co2 emissions for heating a medium-sized house determined by oil and gas is roughly thirty times greater than for biomass wood chips. It is a huge difference.

Much safer.

Compared with heating unit employing fossil fuels, biomass system release much lower number of pollutants in to the atmosphere. This guarantees very little health problems for customers, and lowered chance of asthma, bronchial troubles and other medical concerns.

Biomass heating systems can generate considerable cost savings versus conventional heating. The degree of saving vary depending upon the particular system chosen. Furthermore the environmental benefits are a significant reduction in carbon emissions. Getting and looking for Biomass boilers is straightforward; provided that you did your research.
