Edmonds HVAC Safety Tip: Clothes Dryer Ventilation

Monday, January 9th, 2012

It’s important to maintain the ventilation system in your Edmonds home for many reasons. Increasing the efficiency of your HVAC system and lowering your utility bills are a few of them, but safety is the best reason to keep your vents clean, particularly your clothes dryer vent.

Clothes dryers are one of the leading causes of house fires each year. Poorly maintained venting systems and improper installation are usually the cause. Protect your home with these maintenance and safety tips.

Even if you clean out the lint trap after each use, lint can still get trapped in the exhaust vent and cause a fire hazard or a potential carbon monoxide leak with gas dryers. Maintaining proper ventilation for a clothes dryer includes cleaning out the exhaust duct and hose. To do this, you just need to unplug your dryer and detach the hose, which can be removed with common household tools. If you already do this regularly and find an abnormal amount of lint and debris, call an HVAC technician to inspect it. There could be something in the duct system blocking the ventilation for your dryer.

At least once a year, you should also have a qualified technician inspect and clean your exhaust duct and make sure you have the proper style hose. If you have a foil or vinyl hose, you should replace it with a flexible metal one that is fireproof. You might want to consider installing a dryer box, which protects the flexible hose and saves space.

Dryers that aren’t properly installed or put in areas that could create hazards are often found in older homes; however, some newer homes are built with designs that create longer ventilation paths and more potential for debris to get trapped inside the ducts.

Don’t wait until a hidden safety issue turns into a fire or carbon monoxide hazard in your Edmonds home. Inspect and clean your exhaust hose and duct today!

Green Lake HVAC Guide on New Air Filter Ratings

Friday, January 6th, 2012

Every Green Lake home has need of a handful of filters that provide with comfortable, affordable air quality and temperature control throughout the year. So, when buying a new filter or upgrading your current system to provide the right comfort level for your home, there are a few things to consider. First is the actual rating of your filters. Every filter is rated for a particular level of efficiency. The higher the rating, the more particles it catches, but also the more it will cost.

Air Filter Ratings

Air filters are rated with a number of scales but the only one that really matters is the HEPA filter rating. HEPA stands for high efficiency particulate absorbing. These types of filters are considered the best on the market. A HEPA filter comes with a number of options. The actual device that uses the filter will have an MERV rating that corresponds to how small of particles it can capture.

An entry level MERV rating is usually around 10 and will capture most major particles like dust, debris, dander and pollen. However, the highest rated HEPA filters have MERV ratings of 13 and can capture particulates as small as 0.3 microns 99.7% of the time.

Some filters are even capable of capturing viruses and bacteria, which are often much smaller than those other particles but can be caught in the debris field through the filter.

What You Actually Need

So, what does your Green Lake home actually need? It depends largely on how much you need to filter out of your indoor air. Most often, the contaminants you should worry about include dust, pollen and dander which mean a modest MERV 10 air filter is plenty.

However, if your air is filled with smaller contaminants like mold spores, a high grade HEPA filter is a must – not just for your comfort but for your health.

There are also other indoor air quality products you can get to supplement your indoor air quality system. These include air cleaners with electronic ionization, UV germicidal lights to target airborne pathogens and humidity control devices to create the ideal environment in your home. Whatever you choose, know that it is possible to keep your family comfortable year round.

How Much Ventilation Do I Need for My Mercer Island House?

Friday, December 2nd, 2011

By now you’ve probably heard how important it is to have good ventilation in your Mercer Island home. Especially if your home was built in the 1980s or early 1990s when ventilation issues were prevalent, you may not have enough clean air moving through your home. But, how much ventilation do you need? What is enough and if you don’t have it, how do you ensure your home is retrofitted properly?

How Much Ventilation?

Most recommendations for ventilation come from the Home Ventilation Institute, which provides a series of standards of measurement for builders and contractors retrofitting homes for better ventilation. Here are some of their recommendations and how they might apply for your home:

  • Bathroom – Small bathrooms (less than 100 sq. ft) need 1 CFM per square foot of bathroom. The number goes up for each fixture if you have a large bathroom.
  • Kitchens – Your kitchen range needs at least 100 CFM if against the wall and upwards of 150 CFM if on an island.
  • Ventilators – If you have an HRV for your home, you should have at least 100 CFM for 2,000 square feet and another 50 for every 1,000 square feet of home size being ventilated.
  • Home Ventilators – The actual volume of CFM for ventilators depends on the type of ventilator being used. For example, a whole house ventilator needs upwards of 6,000 CFM for a 2,000 square foot home. Attic ventilators need 1,400 or more.

So, what does this mean for your home? It means in general that you need a lot of ventilation and that the best way to get it is through mechanical ventilation techniques combined with your air handler and ductwork.

Especially if you recently added insulation and weather proofing to your home but have not yet updated your ventilation, you might have a major air quality problem, so have a professional measure your home’s air flow as soon as possible.

Types of Air Filters: A Tip from Ballard

Wednesday, November 30th, 2011

When choosing an air filter for your Ballard home, there are many options. Each type of material is designed to capture a different type of particle to a different degree, so make sure you choose carefully based on the specific air quality problems your home has.

  • Disposable – Disposable filters are the simplest and least expensive option on the market but they are usually rated as low as 1-5 MERV and don’t last very long. These types of filters are usually designed for basic mechanical filtration to stop debris from causing problems for your furnace or air conditioner and are therefore not ideal for actual air quality improvement.
  • Fiberglass – Fiberglass filters are very common in almost all HVAC systems and are more permanent than disposable filters. They come in MERV ratings of between 4 and 12 and are highly efficient at capturing larger particles like dust, pollen and dander. These can be dangerous, however, as they fragment and can send fibers into the air.
  • Polyester – These have a higher resistance rating than most fiberglass filters and are therefore more durable against larger particles like dust and pollen. They also don’t fray like fiberglass and are more durable over time.
  • Electrostatic – Electrostatic filters have a charge to help collect dust particles and are usually made with multiple layers of polypropylene material.
  • HEPA Filters – This is a completely different category of filters and is designed to capture everything as small as 0.3 microns – well below the threshold most commonly provided by standard HVAC filters. They can be purchased for your HVAC system or as standalone filters for individual rooms.

There are a number of different filter types to maintain the air quality in your home. If you’re interested in getting the most out of your home’s air quality control system, make sure you do it with the best possible device available to your system. Contact a professional if you’re not sure what options will suit you best.

Is My Home as Comfortable as It Could Be? A Question from Startup

Wednesday, November 23rd, 2011

When it comes to your Startup home’s indoor comfort, there are a surprising number of things you need to take into account. 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 and dehumidification 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 checked 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.

How Do You Measure Your Air Cleaner’s Performance? A Question from Bothell

Friday, November 4th, 2011

Your air cleaner is designed to keep your family comfortable and healthy in your Bothell home, regardless of what contaminants make their way inside. This is important because homes these days are sealed up tightly to minimize the loss of heating or cooling, but as a result they have poor ventilation and frequently they will suffer a buildup of excess contaminants like mold, dust, pollen and dander.

To ensure you get the best possible air cleaner for your home, there are a number of measurements available to help you in the purchasing process. Let’s take a look at a couple of those measurements and what they mean.

MERV

MERV ratings are used to measure the ability of a filter to remove dust from the air that passes through it. The higher the MERV rating, the better the filter works at removing particles. The MERV rating scale goes from 1-16 with 16 being the best possible rating you can obtain from a residential (non-HEPA) grade filter. Usually, they are designed to measure things like dander, dust, smog, wood smoke, spores, bacteria and mold.

When choosing an air cleaner, it is recommended that you look for a MERV rating of at least 8, which is good enough to remove almost all common household contaminants. Higher MERV ratings (17 and up) are found in HEPA filters which are considered among the best on the market, able to remove particles as small as 0.3 microns.

CADR

This rating stands for Clean Air Delivery Rate and is a measurement of how efficiently the air cleaner delivers clean air for tobacco smoke, pollen and dust (the common measurements given for each device). This is not a measurement of the efficiency of the device, so much as the speed of it the device. So, the higher the CADR measurement for all three contaminants, the faster those particles are removed from the indoor air.

The best way to choose a device to match your needs is to look for a CADR rating of at least 2/3 of the size of the room you are cleaning. So, if you are cleaning the air of a 150 square foot bedroom, you should get a device with a CADR rating of at least 100.

When choosing a good air cleaner for your home, make sure you do your research and choose on the best possible option for the space you need to clean. MERV and CADR allow you to do this.

The Benefits of Duct Sealing: A Guide from Seattle

Wednesday, November 2nd, 2011

Ductwork is an integral part of any Seattle home HVAC system. It moves heated or cooled air between your air handler and the rooms of your home and it usually contains the filtration and humidity control devices needed to keep your air clean and healthy. Unfortunately, despite how important ductwork is, many homeowners ignore it, even when extra sealing is needed.

What Duct Sealing Does

Duct work ideally should be a closed environment. Crafted of sheet metal, duct work is tasked with keeping the conditioned air in one place until it can be delivered to each room of your house. If gaps open between ductwork or if it starts to erode with time, you lose a lot of conditioned air, and you guessed it, your bills go up.

Unsealed ductwork forces your air conditioner and furnace to work harder, increasing your energy bill in the process. The lack of sealing also makes it possible for things like exhaust fumes to escape the ventilation system and enter your home. This is a serious air quality issue and can be harmful to your health.

Solving the Problem

Fortunately, the problem is pretty easy to fix. You just need to have your ductwork checked on a regular basis and sealed when a problem is found. Checking the pressure retention in your ductwork will usually uncover any gaps that need to be sealed and with modern technology, inspections are easier than ever.

How do you know when this is needed? Look for spikes in your energy bill or uneven cooling or heating in your home. If your upstairs bedroom simply doesn’t stay warm, you may need to have your ductwork inspected a little more thoroughly. Don’t forget your ductwork – it is just as vital a component in your HVAC system as the furnace, air conditioner or air handler.

Will My Air Cleaners Reduce Health Risks? A Question from Monroe

Friday, October 28th, 2011

There is a lot of talk these days about how important it is to have a good air cleaner in your Monroe home. If you don’t have one, you’re putting yourself at risk, or so says common knowledge. But, do air cleaners really reduce health risks, and if so, by how much?

What Air Cleaners Do

Before we can say whether an air cleaner has any positive health effects, we must first look at what they do. Air cleaners are designed to remove certain particles from the air inside your home. Different air cleaners are designed for different levels of removal.

Ratings like the MERV of an air cleaner measure how small of particles the device can remove. Additionally, the type of cleaner will determine what it is best at removing. Mechanical filters are the most efficient at removing dust, pollen, and dander while electronic filters are best for smoke, bacteria and mold spores.

So, What Impact Does this Have on Health?

The big question then is what kind of health benefits you will gain from a high end air cleaning system. If your home isn’t prone to a large number of contaminants and you have good ventilation, the difference may not be that big, but for those with a well-sealed home, pets, humidity problems or any number of other indoor air contaminant sources, an air cleaner has a tremendous impact on your health.

The problem is that when the house gets sealed up so tightly, we put our bodies at risk of contamination from gasses and pollutants that would otherwise dissipate into the air. Those with asthma are put at an increased risk as they breathe in a variety of different triggers like dust, mold and dander.

An air cleaner removes these threats and while they don’t have a proactive effect on your health – you won’t suddenly lose weight or never again get the flu – they can remove many of the negative effects that poor air quality has on your body.

So, should you get an air cleaner for your home? In most cases, the answer is yes, but if you’re still not sure, consider getting your air quality tested. This way you’ll know exactly what you’re breathing and what kind of impact it’s having on the health of you and your family.

How Do I Reduce Dust in My Home? A Question From Ballard

Wednesday, October 5th, 2011

Dust is everywhere. There is no way to stop it from occurring, so instead we turn to cleaning and filtration to keep the amount of dust circulating through the air in your Ballard home to a minimum. Luckily, there are quite a few things you can do, even without installing new equipment, to reduce your dust levels.

Duct Cleaning

First on the list is regular duct cleaning. You dust your furniture and your floors, so why not clean out your ductwork? Properly cleaned ductwork is very important because of just how much stuff can build up in there over time. Imagine regular air flow in an enclosed space that never gets cleaned. How much dust and debris do you think could build up over the course of a year? Hint: it’s enough to keep a steady flow of dust in your indoor air.

Professional duct cleaning is important and should be done once every year or two depending on how often you use your home comfort system. However, you should also clean in and around the vents and ducts in your home where you can reach. This can be done weekly and will help immensely to reduce dust.

Filtration

Most air filters equipped with high quality HEPA filters work extremely well to remove dust from the air. Because HEPA filters can capture particles as small as 0.3 microns, they won’t just remove dust, but pollen, pet dander and even mold. Mold especially is a problem that occurs in far greater frequency in homes without filtration. Simple air filtration is an affordable solution to a lot of different contaminants, so it’s a good fit for any home.

Humidity

Humidity imbalance can cause dust problems as well. Low humidity leads to more dead skin and dust in the house, while high humidity causes the development of dust mites. Properly regulating your humidity to slightly less than 50% will create a perfect environment in which less dust is created and circulated in your home.

The best way to reduce dust is to take a three pronged approach to indoor air quality. Cleanliness is always first on the list, but after that don’t neglect the value of filtration and proper humidity control. When used properly, these three things will ensure dust never bothers you again.

Regular Duct Cleaning Will Reduce Allergens: Some Pointers From Woodinville

Monday, September 19th, 2011

One of the biggest problems many families face with indoor air quality in Woodinville is the ever persistent presence of allergens. Especially if you have pets or plants, allergens will be in your home from the day you move in. But, that doesn’t mean there aren’t many ways to reduce them – especially in the case of duct work.

Allergens in Your Duct Work

How do so many allergens get into your ductwork? It starts with how the ductwork circulates air in your home. Because air only flows one way and because the ducts are not being used continuously, the air circulated by your air conditioner or furnace leaves behind all sorts of unwanted residue.

In both cases, the air drawn into your comfort system is usually the same air from inside your home. That means it is full of things like dust, pollen, dander and more. Even if the air is drawn from outside, often the case with an air conditioner unit, there are plenty of allergens outside.

How do you stop all of these allergens from working their way into your home and then your lungs? It starts with regular cleaning. You can’t ever truly stop allergens from coming inside or circulating in your air ducts, but you can take big steps in removing many of the contaminants that linger in your ducts.

Annual cleaning of the ducts by a professional will remove excess build up in places you cannot normally reach. Between those cleaning visits, you should supplement the cleaning by dusting and vacuuming vents and the areas of your ducts you can reach.

Going Beyond Cleaning

Cleaning your ducts is a great way to reduce allergens in the house. That alone, along with quality ventilation will take care of the most common allergens. However, if people in your home suffer from asthma or more severe seasonal allergies you may want to upgrade your preventative measures with an air cleaning system.

Whatever your concerns, it is possible to live comfortably in your home despite allergies.
