What Is a Whole House Pressurization Test and Should I Get One?

Wednesday, July 13th, 2011

If you have a forced air heating or cooling system in your home, you also have a system of ducts through which that heated or cooled air circulates. And most people don’t give a second though to those ducts. After all, if your heating and cooling systems are working, the ducts must be doing their job, right?

Unfortunately, that’s not always the case. If ducts are not working properly, the whole system will be in trouble, even when you don’t realize there is a problem. That’s why a pressurization test is so important – it provides peace of mind knowing that your home’s ductwork is not only properly installed, but that it doesn’t need any special repairs.

Why Pressure Matters

Your duct system depends on proper pressurization to evenly and efficiently distribute air throughout your home. Leaks, cracks or clogs in the system can disrupt that pressure and lead to uneven or inadequate movement of air through your ducts. This causes problems you may not notice, so if you haven’t had your ducts checked for proper pressure in a while, it’s worth looking into.

Improper pressurization causes symptoms like hot or cold spots in your home or an overall drop in the effectiveness of your home heating and cooling system. When loss of pressure is due to a leak that lets in unfiltered air from outdoors it can also lead to a decrease in indoor air quality. Often these symptoms are easy to ignore. But by doing so, you only allow the situation to get worse.

A whole house pressurization test is the best way to determine the state of your home duct system. By using high tech diagnostic equipment, home HVAC professionals check over your entire system to determine whether you have a pressurization problem. If so they can then quickly pinpoint the source. Once that’s done, the repairs are usually quite simple and you’ll get much more out of your home heating and cooling system than you did before.

Even if no symptoms of improper pressurization in your ducts have presented themselves, it’s worth having one of these tests performed. Especially if you don’t know when the system was last checked, a whole house pressurization test can help uncover small problems before they turn into bigger ones. And the peace of mind this provides is well worth the day it takes to perform the test.

Control Your Home’s Moisture – Humidity Is Key

Monday, July 11th, 2011

Most people don’t give a second thought to humidity until it is either much too high or uncomfortably low. And if you have a state of the art home comfort system, you’re probably comfortable inside all year long anyway. But there are several reasons to pay attention to the humidity level in your home and take action if you realize that it isn’t providing the comfort level you’ve come to expect.

Many problems arise from excess or inadequate indoor humidity levels. For instance, a lack of humidity causes your skin and nasal passages to dry and crack, which is obviously pretty unpleasant. But air that’s too dry can also make the symptoms of allergies, asthma and colds worse. Anyone in your home suffering from these conditions will be much more comfortable when the right level of humidity is restored. Another great benefit is that the indoor air quality will no longer contribute to longer and more sever colds and flus in the winter.

Too much humidity is a problem too, though. It promotes the growth of mold, which is a big contributor to indoor air pollution. Mold spores are a big time allergen. The more moisture there is in your home, the more mold there’s likely to be. High indoor humidity levels also promote the growth of dust mites, another major indoor air contaminant and allergen.

Of course, you probably have a great indoor air cleaner in place to get all of those contaminants out of your home’s air supply. But if the air inside your home is too moist or too dry, it can actually make it harder for the air cleaner to remove all types of contaminants. Not only are you putting a greater strain on your body and immune system, you’re asking your air cleaners to work much harder, which can cost you money in repairs and filter replacements.

For all of these reasons, it’s important to put in a humidification system to maintain the overall quality of your indoor air. Plus, a properly humidified environment is simply more comfortable to live in. A humidifier can easily be integrated into your current home heating and cooling system, so you don’t have to worry about high installation costs or equipment compatibility. All you have to do is sit back, relax and breathe in the fresh air that your humidification system makes possible.

Considering Remodeling? Tips To Be Sure It’s Done Right

Friday, July 8th, 2011

Remodeling your home is a great investment and can be a satisfying accomplishment once it’s done. Any remodeling project is a major one, however, and therefore requires some strategizing and careful execution in order to prevent setbacks, added expense, and a great deal of frustration. Here are some tips to help your remodeling project go smoothly, and help you keep your sanity.

Think like a Boy Scout

The best first step in any remodeling project is to prepare yourself by planning ahead. Every little bit of time and energy spent on planning and preparation can greatly reduce the amount you have to spend on tough decisions and corrections later on. Before starting your project, be sure to:

  • Hire a professional, licensed contractor to perform the work.
  • Make sure the contractor you hire is well-versed on the most recent building codes in the area.
  • Use a detailed design process to develop a plan for the room(s), choose materials and fixtures, and create a realistic budget for the project.
  • Consider staging the work ahead of time to give yourself a realistic idea of the work to be done and cut down on labor costs.

Be Creative

For most of your remodeling goals and objectives, there will usually be more than one option. By considering all your options and discussing them with your contractor, you can save money while still achieving the desired result. Some examples include:

  • Rather than repairing minor blemishes on walls by doing costly structural work, considering using materials to mask the wall, as long as it is still structurally sound. With minor imperfections, discolorations or slight damage, you can use a decorative painting technique or a heavier, textured wallpaper to cover up the area.
  • Likewise, if a room just needs to be livened up, consider repainting first before getting more involved. You may find that the new color is enough to spruce the area up.
  • Rather than creating new space by knocking down walls or building new additions, try instead to create the illusion of more space. Mirrors, skylights, and additional windows are all simple ways to make a small room seem bigger without the trouble of adding square footage.

By keeping some of these tips in mind, you can help to ensure that your house becomes the dream home you have always wanted, without the nightmares of costly or incorrect updates.

Pest Control

Wednesday, July 6th, 2011

Pests are a virtual inevitability in every home at some point, so it is important for every homeowner to know how to deal with that unwelcome stranger when it comes poking around.

Insects Be Gone

From ants to roaches, insects love to make themselves right at home. They invade in search of food, water, and habitable space, and they don’t care whether they are wanted or not. Here are some helpful hints to get rid of these multi-legged tenants.

Borax works just as well as a pest poison as more expensive commercial products. For roaches, sprinkle a bit in your cabinets. Make sure to take extra care that your dishes are free from the residue. Avoid areas where the borax could affect children or pets. Likewise, make a homemade ant trap by mixing equal parts sugar and borax in a jar with holes punched in the lid.

Ants are also repelled by the calcium carbonate found in common chalk. Draw a chalk line around any visible ant holes to keep them trapped inside. Keep termites away by keeping your yard free of wood debris and standing water. Fix any leaks immediately and clear out any thick growth close to the house.

Furrier Pests

Insects are not the only pests to be concerned with, as sometimes intruders come in a larger, furrier form. Mice and other small rodents are fairly common inhabitants, as well as the occasional garbage-scavenging raccoon.

The best way to keep animals from invading your home is to keep potential entry holes sealed. For a temporary fix, try stuffing small holes with steel wool and covering larger ones with wire mesh. Eventually, however, you should have all holes permanently filled by an exterminator or a contractor who is familiar with the strategies needed to stop these unwanted invaders.

In general, it’s best to avoid poisons that put your family or pets at risk. Not only do poisons create a dangerous environment, they often result in dead pests in your walls or under your floorboards where they are hard to remove. Traps are always best so you know where the rodents are at all times.

If you have tried these tricks to no avail, or you have a serious infestation problem, don’t be a hero. Call a professional and have the whole home treated so you can rest easy.

Keeping Your Home Toxic Chemical Free

Monday, July 4th, 2011

So, you have decided you want to try to go chemical free in your home. Whether you want to be friendlier to the environment at large or just foster a healthier home environment for yourself or your kids, eliminating toxic chemicals is a big step. Below are some tips to help you go about it the right way.

Removing Toxins

The first step is to eliminate some of the major toxic chemicals that may already be in your home. First, make sure your home’s ventilation system is functioning properly. Clean vents regularly and inspect the system and change the filter annually.

Consider using a water purification system to remove chemicals like chlorine — which is used to kill microbes in many water systems — as well as drug residues and heavy metals. Remember as well that lead is a dangerous toxin, so have your home inspected for it. Remove and replace any paint, pipes, or other materials made of lead. This is especially important if your home was built prior to 1978.

Finally, have your home checked for radon and asbestos. These are both harmful toxins that can easily be breathed in without being noticed. Check for radon especially if your home has a finished basement, or if your family spends a significant amount of time in the basement.

Keeping them Out

Now that you have expelled these contaminants from your home, look for ways to avoid inviting other potentially dangerous chemicals in. Most of us use toxic chemicals every day without even realizing. To help keep these toxins out of your home, you should look for cleaning supplies that are chemical-free. Companies that manufacture and distribute chemical-free cleaning products include Method, Seventh Generation and Ecover.

You can take it a step further by using DIY cleansers. Baking soda, lemon juice, vinegar and salt are all useful in household cleaning and are much safer for children and pets than chemical-based products. Drain clearing products contain extremely harsh chemicals that can contaminate water supplies and even damage your plumbing. A combination of baking soda, vinegar and boiling water can be just as effective without the toxicity.

Finally, use soap as an alternative to chemical air fresheners. Simply leave a few bars around the house in strategic locations. The soap will absorb nearby odors. For added effect, use scented soap.

Start with these simple steps and you will be off to a good start in keeping harmful chemicals out of your home and away from your family.

Sealing Your Home Can Bring Big Rewards

Friday, July 1st, 2011

You use a lot of energy – and money! – keeping your house at a comfortable temperature. But if there are holes in the “envelope” or “shell” of your home, air from the outside can get into your home and drive up your energy costs.

Sealing the envelope of your home is one of the most cost-effective ways to improve energy efficiency and comfort. Energy Star estimates that appropriate sealing can save up to 20% on heating and cooling costs.

There are three ways to seal the envelope of your home:

  • Sealing air leaks to stop drafts
  • Adding insulation
  • Installing Energy Star windows when replacing windows

Sealing leaks. It may be easy to find some of the leaks in your home, because you can feel and sometimes even see them (for example, around windows and doors). You can seal these leaks with caulk, foam, and weather stripping.

Other leaks may be hidden in attics, basements, and crawl spaces. Common leak spots include:

  • Recessed lights
  • Outdoor faucets
  • Dryer vents
  • Attic hatches
  • Around light switches and cable, phone, or power outlets
  • Chimneys and furnace flues
  • The tops of walls that lead up to attic space

To find and seal these hidden leaks, it may be advisable to hire a contractor who can use special diagnostic tools. The expense is often quickly paid back in increased comfort and reduced utility bills.

Adding insulation. There are several common types of insulation — fiberglass (in both batt and blown forms), cellulose, rigid foam board, and spray foam. Different types are appropriate for different places in your home.

The strength of insulation is measured by “R-value” – its ability to resist heat flow. The higher the R-value, the more insulating power. Different R-values are recommended for different parts of your house, depending upon where you live.

Insulating your attic may offer significant savings, and can be a good DIY project if you are handy. To see if your attic can benefit from more insulation, look across your uncovered attic floor. If your insulation is level with or below the attic floor joints, more would probably be helpful.

Remember, however, that even well-insulated attics need appropriate ventilation to prevent mold growth in the summer and ice buildup in the winter.

Installing Energy Star windows and doors. Replacing windows and doors is a big project and may not generate enough energy savings to justify the cost. However, if you are remodeling or building a new home, be sure to choose Energy Star windows and doors. Energy Star windows and doors will not only help seal and insulate your home – they will also act as a sunscreen to protect your pictures, furniture, and carpets.

After Sealing Your Home: Check Air Quality!

After any sealing or insulating project it’s very important to have a professional perform a Combustion Safety Test on your gas and oil burning appliances to ensure that they are still operating safely.

It’s rare that homeowners seal their homes too tightly – especially if it’s an older house. However, if you are concerned, you can hire a contractor to test your home’s ventilation. If your home is too tightly sealed, he or she may recommend that you install a fresh air ventilation system.

What is a Green Building?

Wednesday, June 29th, 2011

A green building is environmentally responsible and resource-efficient throughout its life-cycle, minimizing the building’s impact on human health and the natural environment.

Some of the criteria that can go into evaluating a green building include:

  • Location
  • Design
  • Construction
  • Operation
  • Maintenance
  • Renovation
  • Demolition

Of course, there are many different kinds of green buildings, each with its own particular strengths. Here are a few:

Buildings located in New Urbanist communities. New Urbanism is an urban design movement that promotes walkable neighborhoods with multi-use buildings so that residents can live, shop, and work within their local area. The goal is to promote community, reduce the amount of energy used for transportation, and reduce emissions from car travel.

Net-zero buildings. A net-zero building produces renewable energy equal to or greater than the energy the home consumes from public utilities. A net-zero building saves energy by being extremely energy efficient, and by generating its own renewable power using solar, wind, micro-hydro, or geothermal systems.

“Ultra-small” homes. Super-small houses (30 square meters and even smaller!) are a growing trend in home design. Tiny spaces dramatically reduce the occupants’ energy use – in some cases, the entire home can be run on the equivalent of a couple of light bulbs.

Buildings constructed with local, natural materials. Homes made of earth, straw bales, stone, stucco, and other natural materials are often cheaper to build and require much less gas for transporting construction materials. They can also be extremely energy-efficient to operate because the building materials are suited to the climate.

Buildings constructed entirely or in part with reclaimed materials. Recycling keeps building materials out of the landfill and reduces the energy needed to manufacture new items. One commonly-used reclaimed material is shipping containers, which are strong, cheap, and can be assembled in a modular fashion to create homes of any size.

R-2000-certified buildings. R-2000 is a voluntary standard administered by Natural Resources Canada (NRCan) that evaluates three main areas of construction: energy performance, indoor air quality and use of environmentally preferred materials. Builders are given the freedom to choose the best and most cost-effective way to achieve the R-2000 goals, which means they can incorporate any of the techniques or building styles described above.

LEED-accredited buildings. Probably the best-known green building accreditation system, LEED offers third-party verification that a home is above average in the following areas: sustainability of building site, water efficiency, energy use, sustainability of materials, use of resources, indoor environmental quality, location, transportation connections, and innovation in design. LEED-accredited homes are extremely efficient to operate and have a high resale value.

Save by Buying Low, Buying at the Right Time

Monday, June 27th, 2011

Buying a new HVAC system is a big step and a big investment. You know you will be spending a considerable amount of money, but it is worth it to get the right system for your home. However, that does not mean you should not shop around and compare prices before you buy. Prices in this industry are far from static, and you could get a great deal if you do some research and know what you are looking for.

Of course, you first have to have the luxury of being able to shop around. If your HVAC system has broken down completely, you will be much more limited on what options you can explore and how much you will pay for the system that you want.

But if you know that you are going to be replacing your existing HVAC system sometime soon, the best thing you can do is to start looking around at what is on the market now. Get a feel for the type of system that you want, the features that are important to you and what it will cost you to get all of that in one package deal.

You can also compare the prices for the same system offered by various retailers and installation companies. While it may seem like the same system should cost the same everywhere, this is often not the case. Also, different places may be offering special discounts or installation specials at different times, and you want to put yourself in the best position to take advantage of that.

The time of year can also affect the price of the system you are looking at. Buying a heating system in the middle of the summer, for instance, is often a good way to get a great deal. So if you plan ahead a little bit, you can make out big when you see the deal you were looking for.

Staying on top of the market is the best way for you to see how the prices on different systems change over time and you will be in a great position to grab a good deal when it comes up. You can also often get good deals on HVAC systems that are close to being replaced by a newer model. Just make sure that the newer model does not offer too much more than the previous year’s and you will likely come out ahead.

Save Money with Coupons – HVAC and Plumbing

Friday, June 24th, 2011

HVAC and plumbing services are not things that you usually think about using coupons for. After all, you almost never call an HVAC specialist or plumber unless there is an emergency, and that means you probably do not have time to go hunting for a coupon. You are going to go with the person who is able to respond quickly and get the job done fast.

But that does not mean you should have to pay too much for emergency or other HVAC and plumbing services. In fact, if you know where to look, you can find coupons for great deals on anything from annual maintenance to full new system installation. Of course, not all of these deals are that great. But even saving a little on each service will add up over time. Plus, gathering up some coupons ahead of time will make it easier for you to choose a good HVAC service or plumber because you can see which one in your area offers the best deals.

So where do you find these great coupons? Well, a lot of them can actually be tracked down online. A simple search for HVAC or plumbing coupons in your area should turn up quite a few results for services you could use now or in the future. Some of these offer quite substantial savings as well, so even if they are for something you do not need at the moment, take a look at the expiration date. Even if you are not sure you will be able to use the coupon in that space of time, there is certainly no harm in holding onto it just in case.

It is also important to remember that you do not need to stay with the same company that installed your system, for instance, if you can find a coupon for great savings on annual maintenance with someone else. Just about every company in this field is well versed in handling all types of HVAC or plumbing equipment and they can easily take care of a system that another company installed.

Particularly if you are not satisfied with the service that you get from the company you are now using, look around for coupons from someone else. That is a great way to figure out which new company is worth a try.

Save with Maintenance on HVAC

Wednesday, June 22nd, 2011

You can never save too much money by making improvements and taking steps around the house. Of course, it is hard sometimes to see exactly where the money saving opportunities are. That’s because you expect to spend a certain amount on various types of services when you own a home. You know you are always going to have heating and cooling bills, for instance. But are they higher than they need to be?

For many people, the answer to that question is “yes.” And it is not because they use their home heating and cooling systems inappropriately or because they have the wrong equipment. It is simply because they neglect to get their HVAC systems the regular care and maintenance that would keep them running at peak effectiveness and energy efficiency.

When your HVAC system is new, it runs well and can be remarkably energy efficient. However, over time that energy efficiency will gradually deteriorate. This drop off in efficiency is often not obvious at first, but if you compare your energy bills from the year you got your system to bills for the same time of year and same usage five years later, you will probably notice that the bill has gone up quite a bit, and not just because energy prices have gone up.

You can do a lot to prevent this loss of energy efficiency, though, if you simply have a professional HVAC technician come out once a year and give your system a tune up. During this type of maintenance service, the technician will check over your entire system looking for worn out parts and buildup that could be interfering with your system’s performance.

They can clean out any areas of your HVAC equipment that require it and they will be able to make any necessary repairs at that time. Often, a technician performing this type of maintenance will be able to catch minor issues before they are able to develop into bigger problems. And while you still have to pay for the maintenance visit, the cost is much less than what you would pay for an emergency repair.

It also represents a substantial savings over what you would be paying on your energy bills every month without it. Regular HVAC maintenance can preserve the vast majority of your system’s energy efficiency loss over time, and it is never too late to start. Even if it has been several years since you had your system installed, you will still be able to get back the vast majority of your original energy efficiency by starting with regular maintenance now.
