Five Ways to Reduce Indoor Air Pollution This Summer

When most people think about air pollution, they envision smog and exhaust that heaves from factories and cars, contaminating the air that we breathe outside. But did you know that the air inside your home can be shockingly more polluted than what you’re breathing outdoors? Believe it or not, lead, radon, formaldehyde, dust, cleaning chemicals, mold, mites, and pet dander are all hidden pollutants living inside your home, affecting your family’s health on a day-to-day basis. While we don’t want to think about it, it’s a common reality that I see in houses all over our area and it’s doing more damage than you probably realize.

Because people are spending more time indoors when the weather gets as hot as it has been, we are seeing indoor air pollution take its toll more severely, especially in young children and elderly people who can develop asthma or breathing problems due to the hidden contaminants in their home. So what can you do to make sure your air quality is up to par? Here are five simple tips:

Get tested. Radon and lead tests can be done by a professional and are also available in at-home kits. If your home was built before the late 1970’s it’s a good idea to have it tested as lead-based paint was highly common and can cause a range of health problems, especially in young children. As for radon, it just so happens to be the number two cause of lung cancer in the USA.

Watch the water. Mold loves moisture, so if your home regularly clocks humidity levels above 50 percent, you’ll want to start running a dehumidifier. The amount of mold and mildew build-up I see in people’s homes would shock you, yet they wonder why their kids have asthma and their elderly parents can’t breathe. Here’s an extra tip: a humidity reader costs less than $10 at the local hardware store.

Clean your vents. Proper ventilation is vital to ensuring your home can breathe properly. While most people don’t have enough attic ventilation as it is, they also forget to clean the vents that are accessible and easy to maintain. The air conditioning filter, dryer vent, and even a blow-dryer are likely full of dust and dander, so be sure to keep them clean.

Go green. Household plants are a fantastic natural ally in keeping your air quality up to scratch. Palms, ferns, English Ivy, and Peace Lily are common indoor plants that also earn top marks for ridding the air of toxins. Just remember that you’ll need one plant for every 10 square yards of living space to keep the air clean.

Make it a habit. Cleaning the house regularly will improve air quality simply because dust traps chemicals and allergens in it. Upgrade your vacuum cleaner for one with a high-efficiency particulate air (HEPA) filter and make sure to wash kids stuffed animals regularly with hot water as dust mites love living in fabric materials. When you start running low on a household cleaning product, swap it out for an all-natural alternative without the harsh chemicals. While you’re at it, say goodbye to those synthetic fragrances too - according to one study, a popular plug-in air freshener was found to contain 20 different volatile organic compounds (VOCs), including seven regulated as toxic under U.S. law. An essential oil diffuser will do the job without the poisonous toxins.

Keeping Cool as the Temperature Rises

Mother Nature has decided to turn that heat dial up this weekend, leaving many people with nothing to do but crank up the air conditioning. Sure, a little A/C is a great way to provide fast relief, but keeping it blowing all summer long can do a number on your energy bill and your home. So this week I thought I’d put together a few simple tips to help you keep cool, but first, here is a story that might make you rethink your current set up.

A few years ago, I was called to a house in Bristol for a leak repair. When I got to the home, I found that the entire ceiling had fallen onto the dining room table. We hadn’t had rain for weeks, so I was confused how the leak occurred. It turns out that the home had no insulation or ventilation, and to combat the stifling heat seeping into the house from the attic, the homeowner had two window air conditioning units set on full blast all day. The cold air from the units and the hot air from the attic created so much moisture and mold that it completely deteriorated the plaster, causing the ceiling to fall in.

Having little or no insulation and ventilation in the attic will heat up your home like you wouldn’t believe. Most people think insulation and ventilation are only important in the winter, but they work as regulators, controlling air in both the warmer and colder months. Did you know that an attic can easily get up to 150 degrees on a hot summer day? Stand on a chair and put your hand as close to the ceiling as possible. Feel that heat? It’s a telltale sign that your house doesn’t have proper air flow, which, in addition to making you uncomfortable this summer, can also become a breeding ground for mold.

So what should you do? Start by investing in a hygrometer which measures water vapor in the air. A comfortable humidity reading is 30-60%, but 45-55% is an ideal level to maintain. If you’re seeing higher than 60% humidity in any area of your home, you’re going to be susceptible to mildew and bacteria growth.

Remember, attic ventilation allows your home to “breathe” so you want to balance your intake and exhaust to ensure that what is coming in is going out equally. The best ventilation system will include soffit vents which are installed underneath the overhang of the roof to take in the air and ridge vents which are installed at the top of the roof for the hot air to escape. For this method to work efficiently, all louvered vents must be sealed off and you have to ensure that your insulation isn’t blocking the airflow. Believe it or not, most roof manufacturers will void the warranty if a proper ventilation system is not installed. Luckily, new roofing technology enables contractors to add intake ventilation directly into the roof as opposed to using soffit vents so if you’re in the market for a new roof, be sure to ask for that option.

It’s important to note that homes have different characteristics and what works well for one may not work well for another. With the right balance of air, homeowners can optimize their home’s health but it’s always a good idea to get advice from a professional before taking on a big remodeling project. Stay cool friends, and have a Happy 4th of July!

Give Your A/C a Routine Check Before It Gets Beat by the Heat

Now is about the time when your central A/C or window units start to get some heavy play time. But with the first day of summer barely behind us, there are a lot of hot days left for those appliances to continue to perform at their best. A quick maintenance check now will give you peace of mind and ensure that your cooling units won’t kick the bucket during the most critical part of the summer. Plus a regular check-up will likely extend the life of the appliance too. Here are some of the things that you can do.

1. Pick a cooler day, such as tomorrow, to work on your A/C as you’ll need to shut off the power. This means both flipping the switch on the button and either unplugging it from the wall or locating the exterior shut off box on a central A/C unit. Remember, these are run on electricity so it’s always better to be safe than sorry. If you have a breaker box, you can cut the power there too.

2. For those of you with an exterior compressor, it’s time to remove the fan. First, unscrew the fan cage with a screwdriver and then take the fan right out of the unit. You’ll be shocked to see how many leaves, pollen, and debris can accumulate here. Clean the interior of the unit out with a regular or wet/dry vacuum and wipe down the fan blades too. Any dust, dirt or pollen will slow your A/C down and since there has been so much this year, it’s worth doing a thorough job.

3. Next, use a garden hose to clean the fins from the inside out. I know I spoke about the wonders of a pressure washer last week, but A/C unit fins are delicate and a pressure washer will break them. For this job, stick to the garden hose with a light flow of water. After you clean the inside, you can repeat on the outside. If the exterior is really dirty, you can apply a non-toxic cleaning solution, but just be careful not to damage the fins by scrubbing.

4. Like I said, those fins are easy to break and you may notice that the metal is bent in some places. This can cause air flow reduction and less power in and out of your machine. Using a butter knife, straighten any misaligned fins, taking caution not to pierce the tubing underneath.

5. Now you can put the unit back together. I would clear all debris from around the base of the unit as anything that is constricting the airflow will make the unit less efficient. This is a good time to take a level to it as well. If the unit is out of alignment, this can cause improper function. Remember, the ground often shifts so checking it periodically is a good idea.

6. Finally, it’s time to move inside and clean the vents and filters. Most HVAC specialists will recommend changing the filters at least twice a year and for window units, I recommend cleaning them at least once a month. Not only will your air flow be more efficient, you’ll also reduce the amount of dirty air blowing through the house. When replacing filters, make sure to match the airflow rating from your previous filter to ensure that it will work properly.

Now it’s time to breathe easy and turn your units back on. Remember, there are some jobs that should only be tackled by a professional, so if you come across a leak, major rusting, or something else that doesn’t seem quite right, do yourself a favor and get in touch with an HVAC expert. An early catch might just save you from suffering through a stifling, uncomfortable summer and an expensive bill.
