What Is the Most Efficient Way to Heat My Home? A Question from Washington

Wednesday, November 23rd, 2011

When it comes to Washington home heating, efficiency is one of the main factors most people take into consideration. There are quite a few different options in terms of home heating, including furnaces, heat pumps, and boilers, and each of these have their own set of advantages and disadvantages depending on your own particular situation.

For better or worse, there is no one system that is universally more energy efficient and effective than the others. The one that will turn out to be the best choice for you is the one that fits best with your specific heating needs, the climate you live in and the relative price of the fuel sources available to you.

For instance, if you live in a relatively moderate climate, a heat pump may very well be a good option for you. These systems are able to operate much more efficiently than furnaces because they extract heat from the air rather than generating it themselves. That means that in the winter, a heat pump can take heat from the outdoor air and pump it indoors to heat your home. In the summer, the heat pump can actually do the opposite, taking the excess heat from indoors and transferring it out to provide you with a yearlong temperature control solution.

Heat pumps generally run on electricity which can be expensive, but since they use so much less energy than something like an electric furnace, they can still be a very energy efficient home heating option. However, these systems are not as effective in areas with harsh, long winters, and so would likely require a supplemental heating system as well. Also, the lower the outside temperature, the less efficient a heat pump is going to be.

Furnaces, on the other hand, are quite effective at heating homes no matter how harsh or cold the climate. Gas furnaces are generally the most popular of the models available now, mostly because the cost of natural gas is lower in most areas compared to the cost of other potential fuels.

However, it may be worth considering an oil or electric furnace if these types of energy sources are relatively inexpensive in your area. No matter what type of furnace you get, you’ll be able to choose how energy efficient you want it to be as well, with lower efficiency 80% AFUE furnaces costing substantially less than those with an AFUE of 90% or more.

Things You Should Have Inspected: A Tip from Capitol Hill

Wednesday, November 16th, 2011

Life would be great on Capitol Hill if we could just depend on things to work and last without requiring any sort maintenance or upkeep. Unfortunately, that is not the case. As good as modern manufacturing and engineering are, our devices, appliances and machines still need attention in order to stay in peak condition.

The Body Is a Machine

To illustrate this, think about the human body. We put a lot of wear and tear on ourselves, which can lead to minor illnesses, injuries and the like, especially when combined with the effects of aging. One way we attempt to stay ahead of the game is to get an annual physical. Once a year, we pay a visit to our doctor to make sure everything is in tip top shape. He checks everything out, lets us know what’s going on, helps us treat anything that may be acting up and then off we go, ready to go for another year.

And So Is Your Furnace!

Likewise, your furnace needs annual attention as well. Although newer electrical furnaces can go up to three years without regular maintenance, gas and oil models should be inspected every year, as should older systems. During an annual inspection, an HVAC professional will:

  • Clean out fuel lines, keeping every flowing freely and efficiently.
  • Check for parts that are wearing out or need to be replaced.
  • Clean and inspect the heating ductwork as well as the vents.

These simple and routine maintenance tasks can extend the life of your furnace by years, keeping your home warm and your heating costs low.

Annual inspections and maintenance are important for health and longevity, both for you and your furnace. You can even schedule your physical and your furnace inspection around the same time so you don’t forget. Make an appointment for your car while you’re at it, too.

HVAC Maintenance the Whole Family Should Know: Some Pointers from Washington

Wednesday, November 9th, 2011

If you think the most important thing a heating and cooling (HVAC) system can do in your Washington home is to provide indoor comfort, you are right. But there is another thing an HVAC system does that is very important and it affects your entire family. It provides a safe indoor environment, too.

Besides warmth in the winter, a finely-tuned HVAC system can clean and filter the air you breathe. That’s important to people who suffer from allergies and is especially important for minimizing the spread of germs that cause colds and the flu. The key phrase in this paragraph is finely-tuned. If your HVAC system is not working correctly – out of tune – it can cost you a great deal in monthly utility bills and can be harmful to your health.

It is important for you and your family members to understand the basics of HVAC system maintenance so you can all understand the symptoms of improper maintenance and its consequences. For example, if anyone in your home is suffering from flu-like symptoms or are constantly drowsy or listless, they may be suffering from the a silent killer: poisonous carbon monoxide gas. This gas is formed during incomplete combustion of fossil oils like natural or propane gas. A malfunctioning furnace can emit carbon monoxide gases and you may never even realize it, until it is too late. Long-term exposure to the gas can cause brain damage and/or chronic sleepiness. It some cases, it can even cause death.

You may be able to diagnose the problem, but you aren’t qualified to test and repair a furnace that is creating deadly carbon monoxide gas. Your best bet is to call a qualified HVAC contractor who can diagnose the furnace and offer repair or replacement suggestions. But there are things you can do to prevent the build-up of carbon monoxide gas.

Check all exhaust vents, like chimneys and flues for any blockages. A blocked or partially blocked vent can cause the build-up of carbon monoxide gas. And never, EVER, use a gas or propane powered heater in an unvented area of your home. These types of heaters create various levels of carbon monoxide gas that needs to be circulated out of each room and replaced with clean, fresh air. So, your family can actively ensure that there is no debris, bird’s nests, animals, leaves, or snow in the ventilation system.

You can also “help” your HVAC system by keeping vents clean by vacuuming dirty vent grilles and, in general, keeping the home clean. The cleaner the home, the easier it is for your furnace to do its job and the easier it will be for you and your family will breathe. These are a few easy maintenance tips will keep you and your family warm – and safe – this fall and winter.

Benefits of Replacing Your Furnace in Washington DC

Wednesday, November 2nd, 2011

You are about to make one of the largest purchases in your life – a new furnace. Maybe your old furnace is on life support and needs immediate replacement or you are looking for a better, more efficient furnace that will raise the comfort level of your Washington DC home while reducing utility bills and carbon emissions.

If the furnace in your basement, crawl space, or attic is 15-20 years old, it may be a single-stage 80% percent efficient model, which doesn’t meet the higher efficiency standards of today’s models. It uses more energy, i.e. gas, oil, or electricity, to operate. And a single-stage furnace does not always provide even heating to all rooms in the home, based on the varying winter weather conditions. There may be large temperature variations from room to room.

Your new furnace will likely be more efficient and environmentally friendly than the one it is replacing – which are the two biggest benefits to replacing an old furnace. So, let’s take a closer look at these benefits, which link energy efficiency to the latest technology – namely two-stage furnaces and variable speed motors.

Two-stage furnaces start out by running in a first stage, which uses less than 70% of its capacity. This stage works well on moderate winter days. On colder days, the furnace will meet your extra heating demand by adjusting to the second stage in the heating cycle. Since the furnace spends most of its time operating in its lower capacity (first or single stage), it burns less fuel than a traditional furnace that always runs at full capacity and then shuts off when heating demand is met. You will see lower utility bills and a shorter payback period on your new furnace investment.

Variable-speed motors can actually save you money on your energy bill as they consume less electricity than standard motors. Variable speed furnaces save you money by having a higher SEER rating. SEER is the abbreviation for seasonal energy efficiency ratio. The higher the SEER, the more energy efficient the unit. The low operating costs of a variable speed furnace can allow you to run your furnace blower. With the low operating costs of the variable-speed furnace you can constantly run your blower without the worry of driving up your utility bill, allowing for continuously filtered air.

The U.S. government, as well as local governments are making it more tempting for homeowners like you to purchase new energy efficient furnaces, too. Government agencies have been offering tax credits to homeowners who switch to energy-efficient appliances, including heating and cooling products. Utility companies also offer rebates to homeowners who wish to lower their utility bills by using high-efficient appliances. Chances are, your local utility has some type of rebate program in place.

And when you shop for a new furnace, look for add-on equipment such as electronic air cleaners and programmable thermostats. Each will raise the comfort level you will be enjoying from your new furnace.

Do I Need to Supplement My Heat Pump with Another Heating System? A Question from Washington

Wednesday, October 26th, 2011

People often turn to heat pumps as a solution for their Washington home heating and cooling needs because they want a single, all-inclusive system that covers all the bases. The convenience and simplicity is part of the allure of choosing a heat pump to begin with.

However, it’s not always that simple. There are situations where a heat pump is not enough to handle the needs of the whole home. This doesn’t necessarily mean that the whole idea goes out the window, but the heat pump may need some help in the form of a supplementary heating supply.

Here are some reasons/situations that may call for a supplemental heat source in addition to a heat pump:

  1. A Particularly Cold Climate – Although heat pumps can serve as the primary heating system when temperatures drop as low as 30 degrees Fahrenheit, they have trouble keeping up when the cold snap lasts longer than a few days. In any climate where temperatures dip below this mark for a length of time, a supplemental heating system is recommended.
  2. A Large Home – Heat pumps come in many different sizes, but if yours does not have the capacity to match the size of your home, then it won’t be able to heat the whole house. It’s as simple as that. If you are installing a new heat pump, be sure to get one that is properly sized. But, if you have an existing heat pump that is overmatched by your home’s size, simply supplementing it may be the easiest solution.
  3. The Power Goes Out – A heat pumps’ use of electricity is a benefit in most situations, but unfortunately it means they are helpless when the power goes out. To avoid suffering in the winter chill when a blizzard takes out a local power line, have a backup/supplemental heat source on hand to use until the power comes back on.

Those are a few situations you may encounter in which supplementing a heat pump is a good idea. Remember, though, that each situation is different. When installing a new heat pump, consult with the professional installer beforehand to see if you should also have a supplemental heat system in addition to the heat pump. This is especially important if you live a cold climate.

How to Get Your DC House Ready for Fall

Wednesday, October 19th, 2011

Now that you have put the lawnmower away for the year and pulled the leaf rakes and blowers out of your garage, you know it is also time to make plans to get your DC house ready for the colder temperatures, too. Getting ready for the fall means sealing up your home a little tighter (but not too tight) and making sure all of your heating equipment is in peak working order.

It’s a good idea to make a mental or physical checklist of everything that needs to be done – and why it needs to be done. Here are some basic tips on how to get your house ready for fall. Let’s first look at ways to assist your heating system to do its job and then look at ways to keep your heating system working efficiently.

First, check all areas of the home where there may be heat loss. Replacing screen windows and screened doors with glass windows and storm doors is the first logical step. Keep all of your screens together and store them in an area that’s convenient to access next spring. Check all of the caulking and weather stripping around windows, doors, roof vents, chimney stacks, etc. You may need to remove older caulk and weather stripping and replace it if it is chipped, cracked, or missing.

  • Make a visual inspection of the ductwork in your house. Ensure there are no openings between joints. Keep a roll of duct tape with you to seal off any obvious gaps, even after you have closed or repaired them. It never hurts to use a little duct tape.
  • Check all of your vents and returns for any obstructions or debris. Move furniture or carpeting away from the vents and returns.

Okay, you’ve done a good job of checking your house for leakage. Now let’s check your furnace for ways to keep it running efficiently. Besides providing warmth and comfort to people in your home, a properly tuned furnace will run more efficiently and use less energy – keeping your utility bills down.

Inspect your furnace filter. Since you will be turning your furnace on for the first time in a few months, you may want to replace the filter in the air handling unit which is connected to your furnace through a plenum. Chances are, the filter will need to be replaced and the timing would be right to do it while getting your house ready for fall. If you have a removable electronic filter, give a thorough washing with a soapy solution and rinse it out. Make sure it is dry before putting it back in the air handling unit.

  • Visually inspect the pilot flame in your furnace. The flame should be a bright blue with a slight shade of yellow on the tip. If it is not, there may be incomplete combustion inside your furnace, which should be checked immediately. Call a heating contractor to schedule an inspection.
  • Ensure there is easy access to your heating system by removing any clothes, boxes, furniture which may have accumulated around it.

The best way to get your heating system ready for the fall is to schedule routine service and maintenance visits from your local heating contractor.  Be safe, warm, and comfortable this fall by taking these easy steps.

Home Energy Myths: A Tip From Washington

Wednesday, September 28th, 2011

Measuring and controlling your Washington home’s energy consumption is a little tricky. There are plenty of talking heads and information resources on the Internet that tell you how it’s supposed to work, but in most cases you’ll find that so called common knowledge about your home’s energy use isn’t always true. Here are some of the most common myths and how to differentiate from the truth.

  1. Conservation and Efficiency Are Different – Many people think that by getting an energy efficient appliance, they are conserving energy and helping the environment. To some degree this is true. However, in reality, you are merely reducing how much energy it takes to complete a task. Conservation is finding ways to actually stop using energy for common tasks. Taking baths instead of showers, not watering your lawn, and turning off lights completely are all examples of conservation.
  2. Turning Off an Appliance Saves a Lot of Energy – Regardless of whether an appliance is physically on or not, it still consumes power as long as it is plugged in. The only way to completely stop your energy consumption is to unplug an item completely or use a power strip that blocks access to electricity when the switch is turned to off.
  3. Turning on Items Creates a Power Surge – While turning a computer on and off uses a bit more electricity than simply leaving it on all the time, it isn’t a significant difference. In fact, the longer you leave an appliance on, the more it wears down and the faster it starts to use extra power to remain effective.
  4. One Energy Source is Cheaper than Another – This depends largely on the type of energy source you have for heating and cooling, the cost of that source and how much heating and cooling you need. A single portable electric heater is cheaper than running your entire oil heating system. But, electric heaters are rarely cheaper if you use them to heat your entire home.

Myths abound when it comes to energy use around your home. Make sure to get all the facts before making decisions that could end up costing you more money in the long run.

2011 AC Federal Tax Credits: A Tip From Washington DC

Wednesday, September 7th, 2011

You’ve probably heard many arguments for why you should purchase an energy efficient air conditioner in Washington DC. They may cost a bit more up front, but they’ll save you money in the long run by cutting down on your monthly energy bills. They’re also better for the environment because their lower energy usage means less fossil fuels are burned to keep them running.

But there’s another reason energy efficient AC units are better buys than your standard alternative. There are Federal tax credits available to consumers who purchase them. This tax credit can more than make up for the higher purchase price of the units, allowing you to enjoy your monthly savings much sooner and know you’re doing your part to protect the environment.

How to Qualify

In order to qualify for 2011 air conditioning Federal tax credit, you need to purchase an appropriate energy efficient AC system. Your HVAC contractor or salesperson can tell you which models and units qualify for this program. Just make sure you save all documentation and proof of purchase in case you need them to validate your claim.

The AC units that qualify you for this tax credit include those with a SEER (seasonal energy efficiency ratio) of 16 or greater and an EER (energy efficiency ratio) of at least 13. These two numbers are the best and clearest indicators of the overall energy efficiency of the product and can easily be found on the packaging for any air conditioning unit. While a 16 SEER is very good, it is not the highest rating currently available, either, so you won’t be forced to buy the most expensive model available to get your credit.

Credit Details

The tax credit is good for up to 10% of the purchase price of the unit up to $300. Keep in mind, though, that you can only claim up to $500 lifetime towards this program. So if you’ve previously claimed $250, you can only claim an additional $250 for 2011. That’s still a significant savings, though, and well worth looking into if you’re in the market for a new AC unit or system.

So if you’ve been thinking about upgrading your AC system, but haven’t quiet gotten around to, now may be the time to take advantage of this great tax credit opportunity before it’s too late.

Cleaning Air Conditioners in Washington DC

Wednesday, August 17th, 2011

One of the best things you can do to help maintain high indoor air quality in your Washington DC home is to clean your air conditioning system on a regular basis. While these systems make it possible to endured a long, hot summer with minimal discomfort, they can also become a breeding ground for bacteria, mold and other indoor air contaminants that can make you sick or cause other types of problems.

Improving your indoor air quality isn’t the only reason you should worry about keeping your air conditioning system clean. A properly maintained air conditioner will function more efficiently for a longer period of time.

Air Filters

Changing or cleaning out your air filters regularly is one of the easiest and most important parts of air conditioner maintenance. These air filters are your number one line of defense against all manner of indoor air pollutants, but if they become saturated, they can no longer do their job. Fortunately, changing out these filters is a quick and easy job. Just mark the date on your calendar so you don’t forget.

Ducts

Without the system of air ducts that run through your home, your air conditioner wouldn’t be able to circulate all that cool air. But they’re also a very attractive place for dust, pollen, mold and other indoor air contaminants to collect. Unfortunately, the majority of your ductwork occupies space behind walls, beneath floors and in other equally inaccessible areas of your home.

For that reason, it’s generally necessary to have a professional with specialized equipment come out and clean your ducts once a year. By keeping up with maintenance, you can be sure that your air ducts aren’t harboring dangerous contaminants that your air conditioning system can then spread throughout your home.

Cooling Coils

The cooling coil is another part of your air conditioning system that needs to be cleaned on a regular basis. If your cooling coil is dirty, it won’t actually affect your indoor air quality, but it will impede your air conditioner’s ability to function effectively. The more sediment and debris allowed to build up on your air conditioner’s cooling coil, the less efficiently it will cool the air that passes over it. And if it can’t cool the air properly, your air conditioner will have to work overtime to maintain a comfortable temperature inside your home.
