Arlington Heat Pump Tip: Heat Pumps and Humidity

Monday, April 30th, 2012 by siteadmin

Humidity is a big problem for a lot of families. When not properly controlled, excess humidity can lead to damage to your furniture, excess mold growth and dust mites. In the warmer months of the year, this is a big problem. Fortunately, if you have a new Arlington heat pump, you have a strong weapon against excess humidity.

Heat pumps have both cooling and heating modes. In the winter, when your heating mode is active, you likely don’t need dehumidification. However, in the summer, excess humidity can make everyone uncomfortable.

Air conditioning has long been a natural dehumidifier. Because the process works through evaporation and condensation, water can be extracted from the air by the device whenever it is on.

However, for your heat pump to truly provide the dehumidification you need to remain comfortable, it must first have a dehumidification setting – often called the “dry” cycle. During this cycle, the device will dehumidify your home, pulling air from inside the house and extracting moisture from it through the indoor evaporator coils.

Dry cycling is effective because it doesn’t draw new air in from outside to cool your home. It uses the same air already in your home and can therefore remove humidity over time. While new air is draw into your home through vents, the system is designed to continuously cycle the humidity out of the air and keep you from being uncomfortable.

Choosing the Right Heat Pump for Humidity Control

Not all heat pumps offer humidity control settings, so you should talk to an Arlington heat pump professional about your needs before selecting a new model for your home. Make sure it offers the dehumidification options you’re looking for and can cover the full area of your home.

How to Lower Energy Costs for Your West McLean Home: Water Heater Tips

Friday, February 24th, 2012 by siteadmin

If you want to lower the energy costs for your West McLean home, the water heater might not be the first place you’d think to save energy. However, when you add up the savings from a few easy steps that can improve your water heater’s efficiency, it can make a significant difference in your utility bills.

Here are some of the ways you can reduce the use of hot water in the home and increase your energy savings.

Saving Energy by Using Less Hot Water

Even if you own an energy-efficient, tankless water heater, and you try to conserve water as much as possible, hot water usage can always be reduced in other areas. Installing low flow faucets and fixtures can provide up to 60% in water savings because they reduce the flow rate (gallons per minute) for each fixture. Tankless water heaters are also more efficient when they are used with any application with a lower flow rate.

Replacing older appliances that require a lot of hot water with more energy-efficient models is worth the money and effort because of the energy savings you will get in the end. Make sure you fix any leaks on older hot water faucet or fixtures. A leak that costs a dollar or two extra per month doesn’t seem like much, but it will add up over time.

Lower the Temperature on Your Hot Water Heater

For every 10°F that you lower the water temperature on your hot water heater, you save between 3% to 5% in energy costs. The manufactured setting for most water heaters is 140°F, but most homes only require a maximum temperature of 120°F. Check your owner’s manual before you lower the temperature on your water heater to find out what the recommended settings are and how to change them.

Insulate Your Water Heater Tank and Water Pipes

Whether you have a gas or electric hot water heater, you can find fairly inexpensive and easy-to-install insulators or “jackets” for your water heater tank. Every tank has an R-value that determines how much heat it loses, so unless it is a high value, your water heater tank needs insulation. Call a professional or check your owner’s manual for the R-value of your hot water heater, but the general rule is that if the tank is warm when you touch it, you need more insulation.

You can reduce emissions and your energy costs simply by paying more attention to how much hot water you are using in your West McLean home. For more tips and expert advice, call Millie’s Heating and Air Conditioning to speak with one of our technicians.

Lorton Heating Tip: Most Energy Efficient Upgrades for Your Home

Friday, February 17th, 2012 by siteadmin

Before you decide which upgrades will make your Lorton home more efficient, it would be best to get a home energy audit. You can do this yourself with a few simple tests, or you can hire a professional auditor. The auditor will use advanced equipment and techniques, such as blower doors and infrared cameras, to detect air leaks and places that need more insulation.

When your home is properly insulated and sealed, here are some upgrades you’ll want to think about to make your home more efficient.

High-Efficiency Furnaces & Heat Pumps

If you have an old single-stage furnace, it is time to upgrade. These furnaces were designed to run on two settings—either off or on, and when they are on, they run at full speed. Not only do they lose heat this way, but they also take longer to warm up your home. The new two-speed and multispeed models run at lower speeds to maintain a constant temperature. You can also buy ones with variable-speed blowers that operate on various speeds, which are the most efficient. Heat pumps are a good option if you need both heat and A/C in your home. While most heat pumps are manufactured to be efficient by design, the newer models are the most efficient way to heat and cool your home. If you have a heat pump older than 15 years, talk to an HVAC technician about a heat pump replacement.

Tankless Water Heaters

When you’ve upgraded your heating system, it may be time to install a more efficient water heater. Tankless water heaters heat your water with individual units located near hot water applications. You also have the option of installing a single, whole-home tankless water heater, or for appliances that use more hot water, such as dishwashers and washing machines, you can install tankless models just for their use.

Water-Saving Toilets & Low-flow Plumbing Fixtures

Duel flush, or water-saving toilets are an excellent choice for an upgrade if you want to save water. These toilets use less water overall, and you have the option of using more or less water each time you flush. Installing low flow faucets and fixtures can also provide up to 60% in utility savings. Low flow plumbing fixtures reduce the flow rate for each fixture or application, which reduces the overall amount water used in the home. These are a good option if you’ve installed a tankless water heating system. Your tankless water heaters will be more efficient if the sum of the flow rate total for every fixture in the home is lower.

Don’t hesitate to call Millie’s Heating & Air Conditioning if you have any questions about upgrading your Lorton home.

Sterling Heat Pump Tip: Outdoor Maintenance

Monday, February 13th, 2012 by siteadmin

Sometimes, the trickiest part about owning a heat pump in Sterling is keeping the outdoor components maintained. Because they are outside and generally out of sight, it can be easy to forget or neglect them. But because they are outside and exposed to the elements, outdoor heat pump components need attention and maintenance to keep them running properly.

The two most important routine maintenance functions you can do as an owner of an outdoor heat pump are keeping it free of debris and keeping it level.

Every month or so, inspect and clean your outdoor heat pump to make sure it is free of leaves, dirt and other debris. These can easily be sucked in by the fan and reduce the efficiency of the whole system. Turn the power off to the unit and use a vacuum or broom to remove any accumulated debris.

Once or twice a year, use a carpenter’s level to make sure the whole thing is sitting level on the pad. Use the level to gauge both side to side and front to back. While you are doing this, check the insulation for erosion or gaps. If you see that it is not level or the insulation is wearing thin, have a contractor come out reset the unit on the concrete pad or patch up the insulation.

These are two small maintenance tasks that you don’t have to do very often, but they can make a big difference in the performance and life of your heat pump.

In addition, you should always have your whole heating, ventilation and cooling system inspected by Millie’s Heating & Air Conditioning annually in order to keep everything maintained and in good repair.

Burke Heating Replacement Advice: Reasons You Should Consider an HVAC Upgrade

Wednesday, February 8th, 2012 by siteadmin

It’s an eternal question that plagues all Burke homeowners — or anyone who owns a valuable piece of machinery — from time to time.

Is it time to get a new one?

From cars to TVs, the most valuable devices we own have finite lives and eventually need to be replaced. Often it can be hard to know when the time has come to get a new one. Do you fix it one more time? Make due with its limitations? Or finally bite the bullet and upgrade?

The same is true of HVAC systems, sometimes on a larger scale because of the expense and importance. So how do you know when that old HVAC system is ready to be retired and replaced by something new? Take a look at some of these indicators:

  • Repairs are becoming very frequent or costly. This can be hard to gauge, as all HVAC systems need service from time to time. But if you are having a repairman out to your house every month, or if you have spent more in the last year on repairs than a new system would have cost, it’s time to stop repairing and replace instead.
  • Some of your rooms are either to hot or too cold. This means your system is having trouble distributing heat evenly, which is a sign that it is on its last legs.
  • Your home is unusually humid or dusty. This can be difficult to detect, as the change is usually gradual. Humidity and dust can aggravate respiratory problems like allergies or asthma, so a new system may be in the best interest of your family’s health.
  • Your current system is over ten years old. This is about the lifespan of a system. Even if it seems to be running fine, trouble may be on the horizon, and the advances in technology mean that newer systems are more efficient and effective.

If any of these sound familiar to you, it is probably time to upgrade your Burke home’s HVAC system. If for any reason you are on the fence, a consultation with a professional can help you decide on the best course of action.

Annandale Water Heater Maintenance: How to Extend a Life of a Water Heater

Wednesday, January 25th, 2012 by siteadmin

To avoid having to pay for replacing your Annandale home’s water heater, your best course of action is to take care of the water heater you have. Many homeowners forget about this simple part of household maintenance, probably because water heaters are so often out of sight that we take them for granted. For a simple start on water heater maintenance, try this three-step annual routine:

  1. Lower the temperature on your water heater to somewhere between 115 and 120 degrees Fahrenheit. This is more than adequate for all household functions, and it will keep the water heater from overheating. Locate the knob on your unit (refer to the manual or manufacturer website if you have trouble) to dial it down. You’ll never notice the difference in temperature, but your water heater will have to work less and your energy bills will be lower.
  2. Test the temperature and pressure valve by lifting the valve lever part of the way up, then allowing it to snap back into place. This should be followed by a gurgling sound as water is briefly released from the tank into the drain tube. If not, the valve may need to be replaced.
  3. Flush the tank on a smaller scale. Rather than doing a full flush of the water heater, you can do a smaller one in much less time. To do this, just put a bucket under the drain valve and release the valve. When the bucket is full, close the valve back up and drain the bucket outside or into a sink. This will help get rid of sediment, but takes much less time than draining the whole tank.

It is also recommended that you get a professional inspection of your water heater on a regular basis, according to the manufacturer’s recommendations. This three step plan is a good interim measure, however, and it only takes a few minutes each year.

Lovettsville Heat Pump Repair Tip: The Emergency Setting

Friday, January 13th, 2012 by siteadmin

While installing or inspecting your Lovettsville home’s heat pump, you may have noticed that little switch or button labeled something like “Emergency Mode.” And then, you probably scratched your head and thought, “what is that for?”

Hopefully, the emergency setting is not something you will ever have to use. But, it is there for a reason, so it’s possible you may have to resort to it at some point. In that case, it makes sense to know what it is first.

The emergency setting on your heat pump interrupts the normal operation of the device. The compressor shuts off, so the heat pump no longer pumps heat from the outside into the home. Instead, the internal heating element is activated. This backup system is designed to provide a sufficient, albeit minimal, amount of heat when the heat pump is not working properly. The idea is that the element can keep your home warm enough while you get the heat pump fixed.

That’s what the emergency setting is, but when would you use it?

It’s not a trick question. As the name implies, you only want to use this setting in an emergency. For example, if the heat pump has frozen and isn’t operating, the best course of action is to switch on the emergency mode and call a Lovettsville professional to repair it.

You would also want to use the emergency mode when recovering from a power outage. Any time a heat pump is without power for more than thirty minutes the refrigerant can cool and get too thick to properly flow through the coils. Turning the pump back on in this situation can damage it, so instead you would use the emergency mode for a while to warm the refrigerant back up, then return to operating the heat pump normally.

The emergency setting is not to be used in place of a supplemental heating system. If there is an uncharacteristic cold snap, and your heat pump can’t keep up, then it makes sense to use the emergency setting to keep the house warm. However, if you live in a colder northern climate, where temperatures routinely drop below 30 degrees in the winter, you should have a supplemental heating system in addition to the heat pump. Using the emergency heat setting regularly is not a good idea.

What Size Water Heater Do I Need for My Alexandria Home?

Monday, December 19th, 2011 by siteadmin

When installing a new water heater in your Alexandria home, it is important to get one that is the appropriate size. Of course, one that is too small will not handle the capacity you need, so you will be stuck with water that is not quite hot enough.

You may think to just buy one that you are sure can more than handle the capacity you need, but there are drawbacks to this strategy. A water heater that is “too big” will also draw more power, resulting in waste and unnecessarily high bills. Plus, it will cost more up front than you really need to spend.

The trick is to get a water heater that is the correct size for your needs. For a conventional water heater with a tank, the metric you will need to refer to is the unit’s first hour rating, or FHR. To determine the necessary FHR, you first need to determine during which hour of the day your home uses the most water. Typically, this is either first thing in the morning or later in the evening, when most people are bathing. Once you know this, determine what the water usage is during that hour based on average usage for each task. For example, let’s say a typical morning in your home consists of:

  • 3 showers (average of 12 gallons each)
  • 1 food preparation (5 gallons)
  • 1 hand dishwashing (4 gallons)

That’s about 45 gallons of hot water needed during that hour, so you need a unit with an FHR somewhere in that ballpark. The U.S. Department of Energy has a good worksheet to use for these measurements, which includes average usage rates for common household hot water tasks.

If you are looking at getting a tankless water heater system, the process is a little more complicated. The important figure to know in that situation is the maximum temperature increase possible for a particular flow rate. That means adding up the flow rates for all the various appliances you may use at once, then figuring out how much you need to increase the temperature.

If you find any of this confusing, consider a professional consultation during the selection process. That will ensure you get the water heater that is right for you.

A Question from Leesburg: Why Should I Clean My Air Ducts?

Wednesday, December 7th, 2011 by siteadmin

You know it’s important to keep your Leesburg home’s air ducts clean, but why?

Actually, there is no one reason why your air ducts need to be kept clean—there are several, all of which are connected to one another. Here are five of them for you to consider:

  • Efficiency – Clean air ducts allow the air to flow through much easier and more readily, so your furnace, air conditioner or heat pump won’t have to work as hard to ventilate the house. This makes for more efficient operation and lower energy consumption.
  • Performance – When your HVAC system does not have to work as hard to push air through the ductwork, it will perform better. Your home will be more comfortable and better ventilated.
  • Longevity – Because your HVAC system is operating more efficiently, it will be able to perform at a high level for a longer period of time. Well-maintained systems last longer than those that are not taken care of, and cleaning the ducts is part of good HVAC maintenance.
  • Savings – Clean ducts can save you a lot of money over time. Your energy bills will be lower because of how efficiently the whole system is running. And, as an added bonus, your ducts will last longer because of the decreased risk of corrosion and damage from being dirty.
  • Health – Last, but certainly not least, clean air ducts mean clean air, which is important for your health and your family’s health. Especially if you have pets, if you smoke or live with a smoker, or if anyone in the house has allergies or asthma, cleaning your air ducts is a must.

Heat Pumps and Energy Efficiency: A Guide from a Leesburg Contractor

Wednesday, November 23rd, 2011 by siteadmin

Heat pumps offer a number of great benefits. For one, they are inclusive heating and cooling solutions, so they can maintain your Leesburg home at a comfortable temperature year round without the need for an additional system.

They run on electricity, so you don’t have to worry about the inconvenience of additional bills and keeping a fuel supply around. They are also quiet and relatively easy to maintain—the list goes on and on. The point is, provided you live in a climate where heat pumps can operate properly, they make for great heating and cooling options.

One other huge advantage of heat pumps is that they are very energy efficient, often much more so than other heating and cooling options. For one, the heating efficiency of heat pumps can range from 150-300%, meaning that the amount of heat energy they are able to produce is 1.5 to 3 times greater than the amount of electricity they draw to do it. That is an incredibly efficient exchange.

The United States Environmental Protection Agency awards the EnergyStar to devices and appliances that surpass energy efficiency guidelines. Heat pumps that have earned the EnergyStar are even more efficient than their brethren, sometimes by as much as 9%, according to the EPA. If you have an older heat pump in your home already, a newer EnergyStar rated model may be as much as 20% more efficient.

While these numbers by themselves may not seem Earth shattering, consider two things. First, in an age of constantly escalating energy costs, any savings are welcome. Second, rewarding energy efficient homes has been a focus of the federal government for a few years. To that end, homes with EnergyStar rated heat pumps installed may be eligible for a federal tax credit of up to 30%. So, not only do these devices help you save on your bills, but on your taxes as well.

The benefits of heat pumps are numerous, but perhaps none is a bigger plus than their extremely efficient use of energy. You can save electricity and save money, all while keeping your home comfortable year round.

If you are considering a heat pump for your home, these benefits are important to keep in mind while making your decision. And if you have any questions, talk to your Leesburg heating contractor.
