Pittsburgh HVAC Guide: How to Improve Your Indoor Air Quality

Monday, May 21st, 2012

When we think of air pollution we often think of outdoor “smog”, but the air in your home or office may also be polluted, even if it looks clean. Sources of indoor pollution include

  • Mold
  • Pollen
  • Cigarette smoke
  • Household cleaners
  • Household décor and furnishings (like rugs and paint)
  • Household pesticides (like rodent or ant-killers, or plant sprays)
  • Radon
  • Carbon monoxide
  • Building materials (like asbestos and lead)

Indoor air quality is of particular concern in newer, better-insulated homes, or in older homes that have been recently weatherized. The “tightness” of modern houses means that any pollutants that get into the home stay there – and perhaps even increase in concentration over time if the source of the pollution is inside the house.

Indoor air quality problems can cause discomfort and even serious disease, especially in children. The good news, though, is that there are many effective ways to improve indoor air quality in your Pittsburgh home.

There are three basic strategies for improving indoor air quality:

  • Air purification. Air cleaners range from small tabletop models to full-house models that are part of the central heating and cooling system. Small air purifiers are typically not very useful, but central air filters can be very effective at removing airborne contaminants. If your heating and cooling system does not include central air filtration, you should consider an upgrade to a new system.
    • It is important to note that air purification will not remove gases like carbon monoxide or radon from your home. Gas pollution must be remedied by professionals.
  • Ventilation. Many forced-air heating and cooling systems do not bring outdoor air into the home. Kitchen and bathroom exhaust fans and attic ventilation fans (when weather permits) can be very important in promoting the circulation of air. Also, opening windows is very important, especially when doing short-term activities such as painting that increase the number of pollutants in the air.
    • You should also consider upgrading to one of the newer central heating and cooling systems that bring outdoor air into the home.
  • Source control. This is the most important indoor air quality strategy, and in many cases, the simplest one. Source control is definitely the most cost-effective strategy for improving indoor air quality, because purification and ventilation both require a constant use of energy.
    • Switch to all-natural household cleaners, buy household furnishings made of natural fibers (instead of synthetic fibers that can “off-gas” volatile organic compounds). When painting, use VOC-free paint. Quit smoking, if you haven’t already.
  • And, don’t forget to install a carbon monoxide detector in your home, ideally next to the sleeping areas.

Gibsonia HVAC Tip: Seasonal Air Quality Control

Wednesday, January 25th, 2012

For people who suffer from seasonal allergies in Gibsonia, air quality is a key concern. Allergens in the air cause brutal bouts of sneezing, runny nose, itchy eyes and even sinus headaches. Even taking refuge indoors will often not assuage these symptoms, as indoor air is often comparable to outdoor air in terms of allergens and overall quality.

That is, unless you take care to control the seasonal air quality in your home, which can not only help ease the suffering of allergies, but also soothe asthmatics, keep out pollutants and generally promote better overall health.

How do you go about controlling the air quality in your home? To start, try these 9 tips:

  1. Vacuum carpets regularly. Use a vacuum with a HEPA filter and invest in some allergen suppressing bags.
  2. Keep your vents clean. This is also a good maintenance practice to lengthen the life of your ventilation equipment.
  3. Dust hard surfaces and wash bed linens weekly.
  4. Install HEPA filters in your ventilation system, such as in air conditioners or other air handler units. Use a higher rated filter to keep out more allergens and pollutants.
  5. Invest in and use an air purifier. Again, make sure to get one with a HEPA filter.
  6. Have your home tested for radon and carbon monoxide. Have smoke, carbon monoxide and radon detectors working properly at all times.
  7. Use a humidifier to keep overly dry air from irritating sinus passages.
  8. Keep doors and windows closed tight, especially during allergy season(s).
  9. Prohibit smoking inside. Banish smokers to the outdoors.

By taking charge of the air quality in your Gibsonia home, you also take control of a measure of your family’s health. Some of these measures require at least a bit of an investment – for example, higher rated HEPA air filters are often more expensive and need to be changed more frequently – but the benefits to your well being and that of your family are clearly well worth it.

What is Air Purification? A Question from Wexford

Wednesday, October 26th, 2011

The air around us is getting more and more polluted these days in Wexford, and people are trying to do more and more to combat it. Cars come with ratings like “ultra-low emission vehicle” and windmills generate power from moving air rather than burning coal. No doubt, these efforts help, but if you want to take an active role in improving the quality of air in your own home, consider an air purification system.

Simply put, air purification is the process of removing contaminants and pollutants from the air. There are a number of devices on the market that can purify the air in your home. While anyone can enjoy the benefits of cleaner air, they are of particular utility for people which suffer from asthma or allergies, or who live in areas with higher concentrations of outdoor air pollution.

There are three main kinds of air purifiers, categorized by the kind of technology they use:

  1. HEPA filtration
  2. Negative ion generation
  3. Electrostatic precipitation

HEPA filtration purifiers simply filter the air that passes through them using a sieve-like filter or series of filters. Depending on the efficiency of the device and the filter, some of these purifiers can trap not only solid and like particles, but also gases and odors. One advantage of this type of purifier is that the HEPA filters can last for years before they need to be changed.

Negative ion generation and electrostatic precipitation models are more complicated and technical because of the technology they use. Consult with a professional to choose which kind of technology is best for your needs, depending on the air quality problem you are experiencing. Some air purifiers can trap bacteria, viruses, fungi or chemicals, so there is bound to be one that will suit your needs.

After deciding on which type of technology you need, you will also have to choose whether you want a portable air purifier unit or a central system that covers the whole house. Obviously the former works well if you are only concerned about the air in a room or two, while the latter is better if you have chronic asthma or a more widespread air quality problem.

How Can You Improve Your Home’s Air Quality? A Tip from Pittsburgh

Wednesday, October 12th, 2011

One of the easiest ways to protect the health of your family is by maintaining high air quality in your Pittsburgh home. Without good air quality, you run the risk of contracting Sick Building Syndrome or making other problems like allergies or asthma worse. Depending on what type of air quality system you already have in place, there are many things you can do to improve your air quality.

Filter Changes

The easiest way to improve air quality is to maintain the equipment you already have. Specifically, change your filters regularly. Filters each have a specified period of time for which they will last. However, if your home has high levels of larger contaminants like pollen and dander, you may need to change your filter more often.

Beyond filter changes, make sure your filtration device uses high quality HEPA filters, capable of stopping debris as small as 0.3 microns.

New Equipment

Finally, you can buy new equipment that does a better job of removing contaminants from your indoor air. If you have only a simple air filter, consider getting a purifier as well to remove other contaminants like smoke and gas. If you have a smaller piece of equipment that works well but longer keeps up with the entire house, there are larger purifiers on the market that can handle a bigger space. Additionally, proper ventilation can help with your indoor air quality if you don’t currently have enough fresh air circulating through your home.

No matter what your problem, there is a solution you can work toward to keep the indoor air quality of your home high.

Staying Safe with Clean Indoor Air in Gibsonia

Friday, October 7th, 2011

Millions of homeowners are living in polluted air and don’t even know it, and some of them are even in Gibsonia. In fact, the quality of air inside homes is a significant factor influencing the health and wellbeing of millions annually. The World Health Organization estimates that 1.6 million people die every year as a result of poor indoor air quality. That makes it the 8th most common risk factor for death in the world and a huge contributor to cancers and other respiratory health problems.

So why is indoor air quality such an issue? Consider for a moment what a home does. At its core, a home is designed to keep you and your family protected from outside threats. It does that with solid walls, tightly sealed windows and a well-built roof over your heads. But the same technology that has made homes better sealed than ever also contributes to safety and health problems for residents of those homes by trapping air pollutants inside.

What’s at Stake?

The most common indoor air pollutants are mere irritants. Things like pollen, dust and dander are uncomfortable but don’t necessarily make anyone deathly ill. However, when a home is sealed up too tightly and the air isn’t filtered and cleaned regularly, the result can be downright dangerous to the occupants. Those seemingly innocuous pollutants suddenly make up a much larger percentage of the air inside.

In some cases, according to the WHO, the amount of smoke and other particles inside the home can be up to 100 times higher than what is considered safe outside. Now consider the other pollutants that can be inside the house. If pollen and dander cannot get out, what about exhaust from your stove, radon gas in your basement or mold spores in your ductwork.

You’re breathing all of it and the result is a significant increase in health risks for diseases like pneumonia, respiratory disease, and asthma – all of which are highly dangerous to anyone, but especially children and the elderly.

Solutions Abound

Luckily, this is not a problem you must deal with indefinitely. Modern HVAC systems integrate advanced ventilation technology, air filtration and air cleaning systems to remove the vast majority of these pollutants. But, first, you need to have them installed. It’s just a matter of finding the right contractor.

What Happens if You Put Your Air Filter in the Wrong Way? A Tip From Oakmont

Wednesday, September 28th, 2011

Air filters are important pieces in your overall Oakmont home’s comfort system. They keep unwanted debris and sediment out of your indoor air and they help your system run smoothly for years to come. However, if you’re not careful, an air filter put in backwards can lead to quite a few problems with your heating and cooling system.

The Most Common Problems

The most common problem you will face with a backwards facing filter is simple inefficiency. If your furnace is forced to blow air through the non-porous end of a filter, it will take more energy to do so. The blower will be overworked and you will pay more money for your heating. The same is doubly true for an air conditioner which has multiple filters in place to keep outdoor contaminants out of your indoor air.

Beyond the cost of improper filtering, you will likely suffer from a decrease in indoor air quality. The filter is designed to remove a lot of unwanted debris, but only when installed in a certain direction. If you set your filter up backwards, the normally collective end of the device will not face the air supply. In effect, your filter will help keep debris in the air.

This results in a clogged filter and improperly cleaned air when it reaches your lungs. If you have a home indoor air quality system it will help to supplement this problem for a while, but the clog will eventually become too much for your system.

Avoiding the Problem

There are two ways to avoid improper installation. First, you can have a professional install the system for you. Whenever you need a new filter ask someone to come and take care of it. When they do, though, pay close attention to how they set the filter and any other steps they take. By carefully watching you can ideally learn what it takes to do this step yourself and hopefully keep your system running smoothly for years to come.

IAQ – To Zone or Not to Zone my Home Comfort: Some Pointers From Elizabeth

Friday, September 23rd, 2011

There are a lot of decisions to make related to your Elizabeth home’s comfort system. You must decide what type of heating you want, how you’ll implement air conditioning, and then how to keep all of that heated and cooled air clean and healthy in your home.

On top of everything else, you have the option to implement zone control in your house to provide multiple comfort levels for each member of your family. Zone control systems are growing rapidly in popularity because they allow home owners to enjoy an enhanced level of comfort throughout the day, while not negatively impacting any one person.

For example, if it’s chilly outside and you need to turn your heater on, that doesn’t mean everyone in the house wants the thermostat set to 72°F. There are a few reasons for this. You may be in the kitchen, working over the stove or doing dishes where there is plenty of heat to keep you warm. More warm air coming through vents or radiators isn’t going to make you comfortable.

The second floor of a home traditionally needs less heat because warm air on the first floor rises and fills that space. The same is true in the summer when cool air settles in lower floors. Having a zone control system allows you to set specific temperatures in each room which are then controlled by your home heating system. You can even turn off the heating and cooling in a specific room like your office or the attic if it will be empty for long periods of time.

Other Considerations

A zone control system is good for comfort, but also for the overall air quality of your home. Too much conditioned air moving through your ducts carries more allergens and contaminants into your home and causes your air quality system to work harder. Your ventilation system will be asked to work harder as well.

Ideally, a good home air quality system is designed to use as little conditioned air as possible to keep everyone comfortable. A zone control system does this very effectively. When talking to a professional about a new installation, check to find out about programmable thermostats as well. These can make it easier to set and forget the temperature in rooms that are only used for a few hours each day.

Is My Home as Comfortable as It Could Be? A Question From Carnegie

Monday, September 19th, 2011

When it comes to indoor comfort, there are a surprising number of things you need to take into account for your Carnegie home. Of course, you need to have a good heating and cooling system in place so that you can easily maintain a comfortable indoor temperature all year round. But that really isn’t enough when you’re trying to create the optimal indoor environment. So what else do you need to consider?

Humidity 101

Well, for starters, it’s a good idea to check the humidity levels in your home. Improper humidity can lead to all sorts of problems, and it can also make it harder for your home heating and cooling systems to maintain a comfortable temperature. Air that’s too dry doesn’t hold heat as well as properly humidified air, so in the winter, your heating system will have to work harder to keep your family comfortable. Too little humidity can also dry out your skin and cause the symptoms of colds, allergies and asthma to last longer and be more severe.

On the other hand, if there is too much humidity in your home, you’re more likely to develop problems with mold and dust mites. And your home cooling system will have a harder time keeping you comfortable indoors. Luckily, there are plenty of great humidification systems on the market right now that can take care of all of these types of problems for you, and they’re definitely worth looking into if you’re concerned about the overall comfort level in your home.

Indoor Air Quality

Along these same lines, you should take the time to have your indoor air quality upgraded by a professional. Indoor air pollutants are a growing problem, particularly in newer homes that are sealed up tight against the elements. These seals prevent all of your temperature conditioned air from escaping and make your home more energy efficient, but they also lead to inadequate ventilation and a buildup of things like gasses, dust mites, bacteria, mold spores and pet dander in your indoor air.

These are obviously not the types of things you want to breathe on a regular basis, so it’s a good idea to invest in ventilation and an indoor air quality system that can bring in a steady supply of fresh air from outside and remove any harmful contaminants from the air circulating through your home.

IAQ – Ultra Violet Lighting: A Guide From Glenshaw

Wednesday, September 14th, 2011

With a state of the art home comfort system in place, complimented by a high tech indoor air cleaner, you may think you’re set to take on climate and contaminant related challenges in your Glenshaw home. But you’re probably missing one thing, and that’s the ability to remove living contaminants like bacteria and viruses from your indoor air.

Unlike non-living particulate indoor air contaminants, bacteria and viruses are not easily caught by indoor air filters or ionizers. They often slip through and continue to circulate again and again through your home, greatly increasing the likelihood that you and your family will get sick. They also tend to reproduce, so the longer you go without eliminating these germs, the more of them there will be.

Killing those Germs for Good

Fortunately there is a technological solution to this indoor air quality problem. The inclusion of ultra violet lights into your air purification system not only specifically targets bacteria and viruses; it helps to slow the spread of disease when someone in your home gets sick.

UV germicidal lights are extremely effective at removing all types of living contaminants from your indoor air. Unlike HEPA filters and air ionizers, UV germicidal lights don’t try to remove these contaminants by trapping them. Instead, they kill them outright, making sure that the germs can’t stick around to reproduce or work their way free of the containment system.

Installation and Maintenance

For most indoor air contaminants, you want to have someone test your air first. However, with bacteria and viruses, you can rest assured that they are always in the air around you. It often only takes a smaller number of pathogens to make someone ill.

Most UV germicidal lights are easy to integrate into your existing indoor air cleaning system. They are usually installed just past the filters so they can catch the germs without other indoor air contaminants getting in the way. And best of all, UV germicidal lights require very little attention or maintenance.

Simply put them in place and let them do their work. You should schedule a routine maintenance visit every so often to make sure that no part of your indoor air cleaning system needs to be repaired or replaced. But other than that, installing UV germicidal lights in your home allows you to relax and enjoy a completely contaminant free living environment.

Air Conditioners and Humidity: A Tip From Bridgeville

Monday, August 8th, 2011

Ever wonder why all of those air conditioners hanging out of people’s Bridgeville windows are constantly dripping water on hot summer days? All they’re actually doing is disposing of the moisture they’ve removed from the indoor air. That’s right – air conditioners are dehumidifiers too.

When you think about it, it makes a lot of sense. After all, you know how much more uncomfortable 90° is when the humidity’s up around 90% than when it’s closer to 60%. Of course, some air conditioners are better at removing moisture from the air than others, so you should definitely consider how well an air conditioner dehumidifies when evaluating your air conditioning options.

Why Humidity Matters

High humidity, even at lower temperatures is uncomfortable. But there are more reasons than simple comfort to want an air conditioner that reduces indoor humidity levels. For instance, high levels of humidity promote the growth and spread of several allergens like dust mites and mold spores. High indoor humidity can also cause problems for the wood fixtures and furnishings in your home.

The Importance of Proper Sizing

Most air conditioners do a decent job of controlling humidity indoors. But depending on the severity of your problem and the typical levels of humidity in your area during the summer months, you may want to pay special attention to each unit’s capabilities when evaluating your options.

An air conditioner’s ability to maintain proper humidity levels indoors has a lot to do with how well it’s matched to the size of your room as well. An air conditioner that’s too small likely won’t get the humidity or the temperature down to a comfortable level. On the other hand, that doesn’t necessarily mean that bigger is better.

In fact, an air conditioner that’s too large for the space you’re using it to cool will have a hard time bringing down the humidity level. Sure, you’ll wind up with a cold room, but that room will remain damp, making it no more comfortable than it was before the air conditioner was turned on.

For all of these reasons, it’s important to carefully evaluate your options when buying an air conditioner and make sure that the unit you buy is the right kind and size for the area you’re cooling. A little extra time spent researching your options will make your home infinitely more comfortable this summer.

If you have any questions about maintaining your indoor air quality, contact your local HVAC professional.
