What to Look for when a Home is 10 Years Old

Monday, May 30th, 2011

A ten year old home is likely to be in great condition, presuming the previous owner(s) treated it well. But, there are some things you should watch out for that can arise in newer constructions, even if they were treated well.

Poor Craftsmanship

While it is possible for a 100 year old home to have poorly crafted parts, it’s highly unlikely if the house is still intact and is being sold this long after it was built. Newer homes, however, wouldn’t show signs of cheap materials or shoddy work until a bit later in their life. That’s why it is important to pay for a thorough inspection of the property as soon as possible – definitely before it is purchased and possibly again afterwards to check for possible improvements.

Specific things you should check for include roofing, your heating and cooling systems, the insulation and the drywall used. Especially in freshly renovated or built houses it’s impossible to be sure a home was built with the highest standards of modern craftsmanship.

Proper Maintenance

For a home that is only 10 years old, there is a good chance you can get the original records for the heating and cooling system, any appliances in the home and all maintenance performed on them since their installation. If not, don’t fret – a good technician will be able to easily check the status of a piece during an inspection.

You should also check to find out the last time the sewer lines and plumbing were inspected. Owners of new homes often forget to have these things checked because they never deal directly with the contractors after the home is bought. To avoid falling into that trap, you should make sure the maintenance plans have been followed carefully and kept up with since the system was installed.

Overall, if your new home is only 10 years old, you are likely in a very good place. The home will be in good condition, the parts will be new, and your heating and cooling system should be efficient. Original parts installed during construction may need to be replaced, but otherwise, if everything else checks out, you can count on having a comfortable, wonderful place to live for some years to come.

Home Repairs You Don’t Want to Ignore

Friday, May 27th, 2011

There are a lot of things you need to take care of around your home. But, everything costs money so many homeowners will put off certain home repairs for weeks, months or even years until they can afford them. However, there are certain things around the house you simply should not put off. Not only can they cost you more money in the long run, they can put your home and your family at risk if you wait too long.

Dirty Filters

Dirty filters in your air conditioning, heating, or air quality system are a problem. Not only do they force your HVAC system to work harder to maintain a good temperature, they are frequently a major cause of airborne contaminants and pathogens. Imagine it this way; those filters are meant to remove something from your air. If they get dirty and are not replaced or cleaned, they probably aren’t working any longer and you can get sick. Dirty filters are inexpensive and easy to fix. Both you and your HVAC repairperson should see to them regularly.

Dryer Vents

Clogged dryer vents are more than just an inconvenience – they are dangerous. If your home has dirty dryer vents, the exhaust from your dryer isn’t able to escape. When this happens, heat will build up in the ducts. Not only can exhaust backup into your home, the risk of a fire goes up significantly. Have your dryer vents cleaned at least once a year and if you live in a two or three family house, make sure it is more often – closer to every 6 months.

Flexible Gas Connectors

Gas connectors are used to transfer gas from the supply entering your home to various appliances like your stove, water heater and furnace. So, there is a lot of natural gas passing through them each day. If they are not properly cared for, that natural gas can start to leak from the connectors and eventually build up in your home to an unsafe level. You should have a carbon monoxide detector installed on every floor of your home and you should have someone come out and check your system regularly for problems.

Water Leaks

Water leaks are more than just messy – they can cause damage to fixtures and floorboards and over time can lead to the growth of mold and the weakening of your entire home. Especially in concrete or foundational walls, water leaks need to be seen to immediately. Even just a small leak can cost you money and put your home at an increased risk of damage.

My HVAC System Has a 10 Year Warranty – Why Do I Need a Maintenance Agreement?

Wednesday, May 25th, 2011

While every new furnace sold comes with a limited 10 year warranty for the unit and parts, it is a good idea to supplement your warranty with a more complete maintenance agreement with your HVAC provider. Why pay for a secondary maintenance plan when you already have a warranty?

For the most part, the limited warranty provided by the manufacturer is meant to cover things like faulty parts, abnormal breakdowns or recalls. If your system simply needs to get a checkup because you use it a lot or there is a clog that isn’t caused by the actual furnace or air conditioner, you will likely end up paying the maintenance cost. So, by paying for an upgraded service plan, you cover all potential breakdowns and you’ll never again need to worry about your system. It’s like getting the upgraded warranty for a new car that covers everything from a busted crankshaft to old windshield wipers.

Help Your System Last Longer

Another benefit of a maintenance agreement for your HVAC system is that the system lasts longer when it is regularly maintained. The best maintenance agreements come with unlimited checkups and service visits, any day of the week, any time. So, if you think your system is running poorly, call a professional in to check it out and it won’t cost you anything. The ability to do this will ensure your HVAC system lasts significantly longer than if you were forced to wait until you could afford an extra visit from your repair man.

So, not only do you ensure your system keeps working, you add a lot of valuable years to its lifespan. Imagine how much money you’ll save if your furnace or air conditioner lasts for 20+ years instead of just 10. Any breakdowns after the 10 year mark would require hefty repairs or replacement since your warranty is expired. So, it’s in your best interest to keep your system running smoothly throughout its lifespan.

Ultimately, an HVAC system is only as good as what you put into it. If you’re careful about your investments and are willing to spend a little extra now, you’ll stand to benefit far more in the future from a smoothly operating, efficient heating system.

Energy Recovery Ventilator – What Is It and When Do You Need It?

Monday, May 23rd, 2011

It isn’t cheap to heat and cool the air you circulate through your home every day. In fact, heating and cooling can be the most expensive energy related systems you operate. So, the last thing you want is to open a window and pour all of that conditioned air into the great outdoors.

That’s why most modern homes are sealed up so tightly. The heated and cooled air you enjoy so much needs to be retained, both to save money and to reduce your energy use. It’s why the government offers credits for things like insulation upgrades and the purchase of more energy efficient comfort systems.

But, while sealing everything saves you money and reduces your energy use, it can negatively impact your indoor air quality. Without proper circulation and ventilation, the air in your home grows thick with indoor contaminants like pet dander, pollen, dust, and possibly even bacteria or gasses. Normally, these things would be circulated outside through traditional ventilation. But, because of your heating and cooling system, the age old method of cracking a window to let a little fresh air in just doesn’t work anymore.

An energy recovery ventilator solves this problem. Instead of just pouring heated or cooled air outside and replacing it with fresh air, an energy recovery ventilator passes the air through a series of chambers. Within those chambers the heat is transferred from the warmer air to the cooler air.

In the winter, this means the indoor air passes its energy to the incoming air, retaining the heat your furnace or boiler generated. In the summer, the air coming in from outside passes its heat energy to the cooled indoor air as it leaves and only cool air enters your home.

In effect, an energy recovery ventilator works to reduce the cost of both heating and cooling. It is true that most indoor air quality systems are designed to remove many of the contaminants you flush outside, but relying solely on your air purifier or filter puts undue stress on the equipment. Not only will you need to replace filters and cartridges more often, you may need to replace the entire system earlier than you would otherwise. If you’re tired of losing all that conditioned air just to get a fresh breath, look into these amazing machines for your indoor air system.

Heat Recovery Ventilator – What Is It and When Do You Need It?

Friday, May 20th, 2011

While the design of modern homes is to retain as much energy as possible while minimizing the cost of heating and cooling, that very design can have a negative impact on your indoor air quality. Because air cannot pass freely between indoor and outdoor environments, you are stuck breathing the same air day after day.

Luckily, there are t options that will exchange the heat in your indoor air to the outdoor air as it enters your home. In effect, you can retain all of the heat your home produces each day before it leaves the house. It works equally well in the summer to retain the cooled air your air conditioning units produce.

How Heat Recovery Works

Heat recovery ventilators come in many forms, including simple ventilation, heat exchange, or air exchanging. There are even some indoor heat pumps that will carefully draw heat from the air as it’s removed from your home and recirculate it through your air ducts.

The idea is the same no matter how the system is installed. As air leaves your home through a ventilator, a counter-flow heat exchanger transfers energy between the air leaving and entering your home. So, instead of warm air leaving and cold air entering, the air coming into your home takes the heat from the air leaving your home. Air comes and goes, but heat stays inside.

In the summer, the same system works in reverse to remove heat from the air coming into your home and keep it outside. The one thing to keep in mind with a heat recovery ventilator is that it doesn’t retain the humidity in your home as an energy recovery ventilator would. If you live in an area with very high or very low humidity during summer or winter, an ERV may be a better solution for your needs.

Air Quality Benefits

The goal of a good heat recovery ventilator is not just to retain the heated or cooled air in your home. It is also to ensure you have clean, fresh air to breathe each day. Most people don’t realize, but when you don’t circulate your air and your home is sealed up with enhanced weather-stripping and high quality insulation, unwanted contaminants begin to build up. A heat recovery ventilator makes sure you not only get fresh air, but that it’s properly filtered and the heat or cooling your comfort system produces is retained. No money is lost, energy is saved, and your family stays comfortable and healthy – everyone wins.

Understanding House Ventilation Options

Wednesday, May 18th, 2011

All the fancy air quality control tools in the world are useless if you don’t have a good ventilation system to circulate air through your home each day. An air filter removes larger particles like dust, dander and pollen, and an electronic air filter removes smaller particles like bacteria, mold, and gases. However, your indoor air will still be poor without a fresh supply of air constantly circulating in from outdoors.

Types of Ventilators

There are a few options here, depending both on the number of contaminants your home has and the amount of heated or cooled air you are willing to lose each day through vents.

The simplest method is an exhaust fan. Fans blow air from your home, creating a negative pressure zone inside. Air inlets then allow new air to enter your home and equalize that pressure. There are also balanced exhaust fans – one fan blowing indoor air out and another fan pulling fresh air in. If you have open flames or gas burning appliances, a balanced exhaust fan is necessary to keep the flames from going out due to the negative pressure caused by a single outlet exhaust fan.

Traditional ventilation, while simple, is also inefficient. In the middle of winter it blows all of your heated air outside and in the summer, it does the same to your cooled air. Your home comfort system likely can keep up with the loss of heat or cooling, so you won’t be less comfortable, but you will certainly pay more on your energy bill.

That’s why heat and energy recovery ventilators are popular in many homes. Especially if you went to the trouble of having your home sealed up tightly to minimize energy loss, these ventilators will save you money.

When air is ventilated through a recovery unit, the energy and heat is transferred between indoor and outdoor air as it passes. In the winter, this means the energy in your indoor air is retained and during the summer, the energy in outdoor air is removed before it enters your home.

Which Method is Best?

The method you choose will depend largely on your current cost of heating and cooling and what types of contaminants you face. Energy recovery ventilators have the added benefit of patching directly into your indoor air quality units, so you won’t need to worry about new contaminants coming in either.

How a Thermostat Works

Monday, May 16th, 2011

Your thermostat is designed to closely monitor and maintain the temperature in your home. When you flip the switch, you want your furnace or air conditioner to respond immediately. So, it’s a good idea to learn how it works so that if there is a problem, not only will you know better what needs to be fixed – you can decide whether to call a professional in for help.

Thermostats shouldn’t need input from you other than to set the initial temperature. From there, they are automatic switches. A thermometer inside the thermostat measures the indoor air temperature. When it gets above or below the limit you’ve specified, it triggers the thermostat to send a message to your home comfort system and keep things nice and comfortable.

Types of Thermostat

Thermostats come in two forms –electromechanical and electronic. An electromechanical thermostat is the simplest and has been used for decades to regulate temperature in homes. It has a simple strip or coil of metal that expands as the temperature rises and contract as it lowers. A mercury thermometer is placed on top of the strip. The coil’s movements cause the vial to tip as the temperature changes. There is a pair of electrical contacts on either end of the vial. The mercury can absorb that electrical current when the electrical contacts touch the thermometer. The mercury then acts as a switch to turn on your comfort system.

An electronic thermostat simply has an electronic sensor that measures the indoor air temperature. You set a temperature for your room and when it changes significantly, the switch inside your electronic thermostat is triggered, causing it to turn on your comfort system.

Ways to Upgrade Your Thermostat

Most homes only need the bare minimum in their thermostats. However, there is some very exciting technology on the market these days that can add quite a bit of value to your system. Not only can you install a programmable thermostat, you can opt for zone control systems that allow multiple thermostats in different rooms of your home.

Programming allows you to set temperatures for certain times of the day. This is especially great if you are gone from the house for long periods of time each day. Why heat or cool a home when it is empty? And if you have multiple people with different temperature needs, zone control temperature control allows you to set specific temperatures for specific rooms in your home – a very enticing option for large families or multi-story homes.

Installing Automatic Thermostats – Quick Fix to Energy Savings

Friday, May 13th, 2011

While you probably spent a lot of time researching your home heating and cooling system to make sure you got one with great energy efficiency ratings and all of the other features you were looking for, one thing you may not have thought a lot about is your thermostat. The thermostat in your home is your direct link to your home comfort system, and the type and quality of the product you have in place can have a much bigger impact on the performance of that system than you may initially realize.

Of course, any thermostat will get the basic job done. You set it for the desired temperature and it will communicate that information down the line to the heating and cooling system. But the better the thermostat you’re using, the better the communication and coordination between the two devices will be. And many advanced thermostats come with all types of special features that can both enhance the quality of your indoor environment and save you some considerable money in the long run.

Saving Money with a New Thermostat

So how can a thermostat save you money? There are actually a couple of ways. For instance, an automatic thermostat can be programmed to switch your heating and cooling system on and off at different pre-set times of day. That means you can have the heat or air conditioning turned off during the day and still come home to a comfortable house. Simply set the thermostat to come on right before you get home and you’ll be able to walk into a perfectly temperature controlled environment without having to keep the heat on all day.

Automatic thermostats can come with other great features as well. For instance, you can set them up to maintain different temperatures in different parts of your home. That way, your home comfort system doesn’t have to work harder to keep your whole house warm or cool when only part of it is in use. And when your home comfort system is working less and using less energy, it will last longer so you won’t have to pay for repairs or a new system nearly as frequently as you might otherwise.

You’ll also pay less on your monthly energy bills the whole time, adding up to a great deal of savings. It might never have occurred to you that a new thermostat could save you so much money, but with all of these benefits, it’s definitely worth looking into.

What Do the Energy Stars Indicate?

Wednesday, May 11th, 2011

If you’re in the market for any type of appliance for your home, you’ve probably come across some that boast an Energy Star certification. But what does this really mean? After all, there are all types of special labels that manufacturers put on their products to make them look better, so how can you know which ones are really worth paying attention to?

Why Energy Star Matters

The truth is that no matter what type of appliance you’re looking for, from a coffee maker to a new furnace, buying one with the Energy Star label is definitely a good investment. This certification is conferred by the Environmental Protection Agency (EPA) and it can only be used on products that pass the EPA’s stringent tests for energy efficiency and environmental impact.

Energy Star products create fewer pollutants like greenhouse gasses because they use less energy to get the job done than their inefficient counterparts. This is great for our planet, but it also translates to savings for you as a consumer. Because Energy Star appliances use less energy to heat or cool your home or do whatever else you need them to do, your monthly bills will be significantly reduced.

Quality and Performance Measured

And you don’t have to worry about inferior performance as a result of increased energy efficiency either. Energy Star products can only receive the label if they provide all of the features you’ve come to expect from comparable products across the board. They need to maintain high energy efficiency ratings while still maintaining a superior level of performance.

While it’s true that you may wind up paying a bit more for an Energy Star product, that is only a one-time cost. If you compare the monthly savings you’ll receive by using your Energy Star appliance on a regular basis to what you would pay out over time with a less efficient model, it’s easy to see how the Energy Star product costs you less.

For all of these reasons, the Energy Star rating is definitely worth looking out for when shopping for home appliances and equipment. These products are made to be reliably energy efficient and can save you a ton over the years as long as they’re properly cared for.

What Is LEED Certified?

Monday, May 9th, 2011

If you’ve been looking into purchasing a home or having any type of major construction done, you may have run across the term LEED Certified. Of course, contractors boast of so many certifications these days that it can be tough to tell which you should pay attention to and which you shouldn’t. But the LEED certification is definitely one that’s worth taking into account when you’re choosing a contractor and planning out your project.

The Benefits of LEED Certification

LEED stands for Leadership in Energy and Environmental Design. The standards and guidelines for obtaining LEED certification were put together by the U.S. Green Building Counsel in order to improve construction practices and help buyers find property that meets higher standards in a variety of environmentally significant categories.

For instance, a LEED certified home boasts better water and energy efficiency than the average home that is not LEED certified. It also was put together using techniques designed to reduce carbon dioxide emissions and improve indoor air quality, making it both the healthy choice for you as the consumer and the environmentally responsible one.

When you purchase a LEED certified home, you’re not just helping the environment either. You’re also helping yourself in a variety of ways. That’s because a home that meets LEED certification standards for energy and water efficiency will help you generate smaller energy and water bills each month. That translates to huge saving over time, so even if you pay a bit more initially for your home, you’ll get that money back many times over as time passes.

LEED certification isn’t just something you should pay attention to when you’re buying a new home. Any construction project you undertake for your existing home can also benefit from these guidelines and standards. For that reason, it’s worth seeking out a contractor who can provide services in line with LEED standards. These types of improvements and techniques need to be incorporated in your home improvement project from the initial planning stage, and a contractor familiar with LEED standards will have no trouble doing just that.

You can also have confidence in the contractor you pick if they carry LEED credentials because they’re not easy to get. Anyone who is LEED certified has put a lot of time and energy into obtaining those credentials and is likely just the type of contractor you’d like taking care of your next home improvement project.
