Tips for Improving Indoor Air Quality During the Winter

According to the Environmental Protection Agency, the air inside our homes and within other buildings can be more polluted than the air that fills the dirtiest, busiest, most polluted industrial cities in the world. Not only that, but research also indicates that lately, people spend about 90% of their time indoors.

For these reasons, the health risks that poor air quality brings to many people can be serious. This is especially true regarding the elderly, the chronically ill, young children, and anyone who suffers from cardiovascular disease or respiratory ailments.

Understanding Causes of Indoor Air Quality Problems

Appliances and devices like outdated, unmaintained, or malfunctioning HVAC systems that release particles or gases into the air are the biggest causes of indoor air quality problems in peoples’ homes. Having inadequate ventilation throughout the home can make it worse. If the air inside is humid or hot, the concentration of pollutants increases.

Some of the most common causes of indoor air pollution include:

  • Household products
  • Improperly adjusted HVAC systems and appliances
  • Smoking
  • Building materials and furnishings
  • Pet dander

Combustion sources also contribute to indoor air pollution. These include:

  • Kerosene
  • Gas
  • Coal
  • Wood
  • Tobacco products
  • Radon
  • Pesticides
  • Humidification devices
  • Asbestos insulation
  • Damp carpet
  • Furniture made of pressed wood

The health effects from indoor air pollution can be experienced upon exposure or even years later.

How to Improve Indoor Air Quality this Winter

The first step in improving the air quality in your home is to identify the main causes of such issues. The presence of any of the above causes of indoor air pollution does not in itself guarantee that you have an indoor air quality problem. However, any ill effects people experience may very well be.

Think about Your Lifestyle and Activities

Another way to identify potential air quality problems is to consider your activities and lifestyle. Do you smoke indoors? Do you own any pets? Do you cook often in the home? The EPA suggests that the most effective way to improve indoor air quality is to control the sources. Always operate stoves with a fan vented to the outdoors if possible, and with wood-burning stoves and other combustion sources, always follow manufacturer instructions exactly.

Improve Your Ventilation

In addition, you’ll need to look for problems with your home’s ventilation. Some signs that may indicate ventilation issues include:

  • Stuffy or smelly air
  • Dirty HVAC equipment
  • Mold in areas where books or shoes are kept
  • Condensation on walls or windows

It’s recommended that you weatherize your home in order to reduce the need to run your HVAC and ventilation systems. Weatherizing your home doesn’t add new pollutants to the air. Adding insulation, weather stripping, and caulking, along with installing storm windows, can make a big difference.

Weatherizing your home can not only decrease your furnace usage but also save you money on your energy bills and reduce polluted air that may otherwise enter the home. Adding a fan that vents to the outdoors over your range will decrease pollutants from cooking. You can also use a dehumidifier in moisture-rich areas.

Have an Air Cleaning System Installed

Having home comfort experts come to your home and perform an air quality audit will reveal sources of pollution, identify pollutants, and help you understand what steps you can take to reduce allergens, dander, and other pollutants.

This is especially important if you or someone in the household suffers from asthma, allergies, COPD, or any other breathing ailment. A-1 Guaranteed can install a new air cleaning system for your home. These systems are able to remove up to 99.98% of all airborne allergens indoors!

Should You Upgrade Your HVAC System Now, Before It’s Too Late?

“If it ain’t broke, don’t fix it,” right? Although this little quip is appropriate for some situations, when it comes to your HVAC system, that may not be the best advice to follow.

Maybe you’ve noticed that your furnace or air conditioner isn’t working quite as well as it used to, or that your heating bill has crept up over the past few months. It’s still working, though, so why call a Contra Costa HVAC company for repairs or replacement?

Because that “kinda working” HVAC system is wasting your energy and money, and you risk having it break down completely at the worst time, like during the middle of winter.

Why You Need to Get a New HVAC System

Not everyone needs a new HVAC system right at this moment, of course, but if yours is several years old, isn’t producing air of the appropriate temperature anymore, is making strange noises, or your energy bills are through the roof, you should seriously consider it. A qualified HVAC company in the Bay Area can assess your system and determine if yours should be repaired or completely replaced.

More Comfort, More Safety

No one needs a furnace breaking down in the dead of winter or an air conditioner going out in the prime of summer. Aging and malfunctioning HVAC systems not only gamble with your comfort levels, but also your safety. Cracks and defects could cause carbon monoxide to leak into your home, resulting in serious health issues…or worse.

Save Energy and Money

You might be surprised at just how much money is wasted with HVAC systems that are not functioning at optimal efficiency. Annual tune-ups are key factors in making sure your system operates as efficiently as possible. A system that is poorly maintained becomes more of a money pit than most people realize. In fact, Energy.gov estimates that 42% of a homeowner’s utility bill is a result of a high-energy, inefficient heating system.

Lessen the Risk of a Breakdown

A mid-winter breakdown of your furnace (or mid-summer breakdown of your A/C unit) can often be prevented by replacing an aging unit before it quits completely. If you notice unusual noises or odors from the vents, a lack of warm or cool air, poor airflow, or unusual noises, that’s your warning that a breakdown may be on the horizon.

Boost the Property Value of Your Home

Your first thought here might be, “I’m not planning on selling my home, though.” Whether you are or are not, an HVAC system upgrade is always an excellent investment. When your home value goes up, that becomes a benefit that will pay off later.

You never know what the future might bring, so if you do end up putting your home on the market in the future, you won’t have to worry about inspections and you’ll also get better offers on your home.

Don’t Take Chances with a Sub-Par Furnace this Winter

It’s too risky to ignore a furnace this fall that isn’t performing up to par. Whether your HVAC system is just a year or two old or it’s going on 10 years of service, it needs to be regularly serviced and maintained with an annual tune-up by a Napa County heating technician.

Doing so can bring small issues to light before they become big, expensive, inconvenient problems. In addition, keeping your system properly maintained saves you money, reduces the amount of energy you pay for on your utility bills, and limits the chances of you having to call for emergency HVAC service in the middle of the night during a holiday.

Most of all, making sure that you have a proper furnace keeps you and your family comfortable and safe. If it’s been a while since your HVAC system has had a tune-up, it’s more than a decade old, or you’re noticing some issues with it, contact A-1 Guaranteed Heating & Air Conditioning and let us know how we can help.

What is a Clean Room and Why Should You Have One?

Half of the biggest wildfires in California in 2021 began in the months of September and October. This is the time of year when the winds are relentless as they bring extremely dry air through the area, exacerbating the risk of wildfires.

However, wildfires are not the only concern during this time of year: It’s critical that air quality remains at healthy levels, but this can prove to be a difficult challenge if a wildfire is in the area.

There are several things every homeowner should do to prepare for wildfire season in California, many of which you may already be aware of. One of the lesser known preparatory steps for homeowners before wildfire season is to integrate a “clean room” into their homes.

What is a “Clean Room”?

A clean room is a closed-off area of a home that is prepared to keep levels of airborne pollutants, particles, and smoke to a minimum during wildfire events. This space should be off-limits to activities that create polluted air, including cooking and smoking.

Windows and doors should always be kept closed during wildfire season to prevent contaminants and smoke from entering. In addition, it’s a good idea to keep a portable air cleaner in the clean room.

The Benefits of a Clean Room

Good air quality is important at all times; however, during a wildfire event, it becomes even more critical. Your home may already have an excellent HVAC system and even a whole-house air purifier, but a clean room can reduce your exposure to smoke and pollutants better than the rest of your home can.

If there is an active fire in your area or the air quality index indicates dangerous smoke levels, you may be advised by the authorities to remain indoors. Conditions can change quickly, so always follow your local media channels for updates.

Do I Need a Clean Room?

Everyone can benefit from maintaining a clean room in their home, as long as it remains safe to stay indoors there. Those who may benefit the most from a clean room during a wildfire smoke event are people who are at an enhanced risk from the effects of smoke. Some of these people include:

  • Children
  • The elderly
  • Anyone with heart disease
  • People with breathing problems
  • Those with a lung disease

Please note: If the electricity in your home goes out, too much smoke is entering your home, or you cannot stay cool at home, seek shelter elsewhere.

How to Set Up a Clean Room

  • The first step is to choose an appropriate room. This room needs to be large enough for everyone to fit comfortably. A good choice would be a large bedroom with an attached bathroom, because you can not only close it off from the rest of the house, but you can do so for a long period of time.
  • All windows and doors must remain closed, but don’t barricade it or do anything that would make it very difficult to get out. If there is an exhaust fan in the room you can use it, but only for short periods at a time.
  • Use a portable air cleaner that is appropriately sized for the room. If possible, run the purifier continuously on the highest setting. If you have a setting that produces ozone, do NOT use that setting.
  • If you have a central HVAC system, consider installing a filter that is high-efficiency with a MERV 13 rating or higher. Run your HVAC system’s fan as often as possible. It should be noted that during times of heavier-than-normal smoke in the air, you should plan to change your air filters much more often than usual.
  • Stay cool, but be careful. You can run fans, central air conditioning, and window A/C units. However, if your HVAC system or window air conditioner has a setting that pulls air in from the outdoors (usually a “fresh air option”) do not use that setting. Close the intake, turn it off, or set the system to instead recirculate indoor air.
  • Do NOT use a portable air conditioner or evaporative cooler that has a single hose unless there is a heat emergency. These single-hose devices can cause substantial smoke to get into your clean room.
  • Don’t create smoke or pollutants in the room. This includes smoking cigars, pipes, or cigarettes, using propane, wood-burning stoves, or gas, spraying aerosol products, frying foods, burning candles or incense, and even vacuuming (unless the vacuum uses a HEPA filter). Wipe surfaces in the clean room with a damp cloth to prevent particles from re-entering the air.
