Statistically Speaking, the Real Heat is on its Way for Richmond

Thursday, July 8th, 2010

FROM RICHMOND TIMES-DISPATCHRichmond, Va. — After three straight days of triple-digit temperatures, here’s a warming thought: Richmond’s traditionally hottest stretch is yet to come.

The second half of July is, on average, the region’s warmest spell, and early August can be brutal, too.

“I won’t say we will continue to have a heat wave, but we’ve got plenty of hot weather to go,” said James Foster, a National Weather Service meteorologist.

The high temperature in Richmond yesterday hit 104, which broke the record of 103 set in 1977. That followed highs of 103 on Tuesday and 100 on Monday.

The heat has been linked to at least three deaths across the state. It has dried lawns, lowered streams, raised concerns about possible water restrictions, and turned lunch-time power walkers into indoor wimps.

“I am so-o-o hot,” said Sadie Williams, 8, of Short Pump as she visited Brown’s Island in Richmond yesterday with her father and two sisters. “Sometimes, the second I get into my car, I start sweating.”

Richmond’s torrid June and July have produced six days so far that reached 100 or hotter. The record for 100-degree-plus days in a year here is nine in 1954.

Virginia is not yet in a drought, but most of the state, including central Virginia, is abnormally dry, according to the U.S. Drought Monitor, a weekly report by federal and academic scientists.

Richmond and the counties of Chesterfield, Hanover and Henrico are considering asking people to conserve water if the dry weather continues. Requests could come as early as next week.

“However, a strong thunderstorm or two can push that time out,” said Arthur D. Petrini, Henrico’s utilities director. “It’s still a little early to predict.”  Gov. Bob McDonnell warned Virginians that the dry conditions make the state ripe for wildfires.

“Something as seemingly benign as parking your car or truck on a patch of dry grass could result in a fire that burns hundreds of acres of field or forest,” McDonnell said.

Ozone, the main pollutant in smog, hit the Code Orange level yesterday and marked Richmond’s fourth straight day of unhealthful air.  Before this week, ozone had not hit unsafe levels since September 2008. Ozone should be in the safe zone today.

Levels of tiny airborne particles such as soot and dust were high yesterday, which created a whitish haze across the region.

Dan Salkovitz, a meteorologist with the state Department of Environmental Quality, said the pollution may have been produced by, among other things, coal-burning power plants that were working hard to produce electricity during the heat wave.

That heat wave should recede slightly today and tomorrow as cooler air moves into the region and drops temperatures into the mid-90s, the weather service said.

That air will be more moist, so “it might feel a little more muggy,” said Tim Gingrich, a weather service meteorologist.

Beyond that, the forecast calls for a cold front to move through the area tomorrow night and Saturday. That should drop the temperature to about 90 on Saturday and might even cause some rain.

Forecasters expect highs in the low 90s on Sunday and early next week.

Hot Weather Pushes Up June Cooling Costs Nearly 76 Percent; Dominion Virginia Power Offers Energy-Saving Tips

Wednesday, July 7th, 2010
  • Bills will rise with higher usage despite slightly lower fuel rate
  • Company urges consumers to take steps to save energy, money
  • June 2010 hottest on record for Richmond since 1943

RICHMOND, Va., July 6 /PRNewswire-FirstCall/ — With the hottest June on record causing Virginia homeowners to use as much as 76 percent more energy for cooling than in an average June, Dominion Virginia Power is encouraging customers to take steps to save energy and money.

The impact of hot weather on June bills could seem magnified because bills in April and May reflected mild weather as well as rebates from a rate settlement agreement. Dominion Virginia Power’s fuel rate went down slightly July 1 but that will not affect previous bills. For rate information: www.dom.com/varates.

“Outdoor temperatures drive home energy usage more than any other single factor,” said Ken Barker, vice president of customer solutions and energy conservation.  ”The extremely hot weather in recent weeks is sending just about everyone’s energy bills higher, but there are steps you can take to control your energy use.” View Dominion’s video on tips for saving energy in the summer at: www.dom.com/about/conservation/summer-tips.jsp.

Some of the lowest-cost, most effective measures include:

  • Raising the thermostat setting to 78 degrees to recognize savings of 1 percent or more on the monthly electric bill for each increase of one degree.
  • Changing the direction of a ceiling fan so that the air blows downward in the summer.  A ceiling fan uses less power than air conditioning and increases comfort, particularly when used in conjunction with raising the thermostat.  It can make the room feel 10 degrees cooler.  
  • Closing drapes during the hottest times of the day to block heat from entering the home. Sunny windows account for a significant amount of unwanted heat and make air conditioners work much harder.
  • Scheduling activities that require hot water — such as washing dishes or clothes — for the early morning or late evening. This will result in less heat and humidity being added to your home.  

More tips and videos on conserving energy are available on-line at:  www.dom.com/about/conservation/index.jsp.

Weather impact on cooling needs

Summer temperatures in Virginia thus far have been significantly higher than normal.  As a result, the amount of energy needed to cool a typical single-family home also has increased significantly. Compared with last year, cooling energy needs for June 2010 increased by the following amounts compared with an average June:

  • Northern Virginia: 55 percent;
  • Richmond: 76 percent; and
  • Hampton Roads area: 53 percent.

Many other uses of electricity — such as lighting, cooking, washing and drying clothes, and computers — are not affected by the weather.

At Marshall Mechanical, we are also concerned about your home’s energy costs. That’s why we specialize in geothermal heat pumps and solar-ready air conditioning units and solar heat pumps.  Simply call us today at 804.323.0189 – we can show you how you can reduce your energy bills by up to 70%.  Even something as simple as a programmable thermostat can help you manage energy costs effectively.

100+ Degrees Again? Take Care of Yourself in the Heat

Monday, June 28th, 2010

From Henrico Public Health Department

RICHMOND, VA (WWBT) – With severe heat expected again today in the metro Richmond region, the Henrico County Public Health Department advises residents to be aware of the signs of heat-related illness and take steps to protect themselves.

Individuals especially at risk for heat-related illness include small children, seniors and people with chronic medical conditions who are not in an air-conditioned environment; however, anyone can be affected by severe heat.

Early signs of heat-related illness can include cramping, fatigue, dizziness and fainting. Heat exhaustion and heat stroke are medical emergencies requiring immediate attention – call 911.

Drink two-to-four glasses of cool fluids each hour; if working outside or exercising, drink fruit juice or sports beverages.

If possible, conduct outdoor activities before noon or at night. Limit physical activity and rest frequently. Avoid sunburn. Wear a hat and light, loose-fitting clothing. Use the buddy system if working outside.

Never leave children or pets in vehicles with closed windows, even momentarily. Temperatures quickly can reach 150 degrees, resulting in heat stroke and death.

Keep cool indoors. Spending at least two hours per day in air conditioning significantly reduces the number of heat-related illnesses; be aware that a fan may not prevent illness when temperatures reach the upper 90s. Seek shelter from the heat by going to air-conditioned facilities such as indoor malls and public libraries.

For more information, read the complete story from the Henrico County Health Department

Heat Pump Fails in Richmond Basement with no Air Flow

Thursday, May 27th, 2010

Unless a low-end unit, heat pumps should last between 10 to 20 years, especially with annual maintenance.  But a lot of it has to do with other factors like proper ventilation, and where the heat pump has been located —  in or outside the home.

This photos is of a 9-year old heat pump unit in a Richmond home that failed because it was installed in a basement with no air flow whatsoever.  That’s why most heat pumps are installed outside the home, particularly in a shady area that gets proper air flow and protects them from the sun.  Being in the sun makes them have to work harder to keep your home cool and therefore they are less energy efficient and thus end up costing you more.

If you are in the Richmond area, and you have a heat pump installed in a basement, you may end up having to replace it earlier than the typical lifespan of the product.  If you haven’t had your heat pump unit checked within the last 12 months, please call us today at 804.323.0189 and we’ll get one of our highly-trained HVAC technicians to inspect the unit and make suggestions on how to keep it running longer and more efficiently.

P.S. If you’d like to know more about the most efficient heat pumps you can buy, including solar units, you can check out the various heat pumps from Lennox on our website:  Lennox Energy Efficient Heat Pumps from Marshall Mechanical, Richmond VA

A/C Efficiency: 5 Tips to Keep Your Richmond Home Cool in Summer

Thursday, May 20th, 2010

Flowers Spring Richmond VAIt may be “spring” on the calendar, but here in Richmond,  the weather has been providing some early doses of summer recently.   Already,  home air conditioners have been humming throughout the region. 

For many, the sound of that A/C unit outside can be justification, in and of itself, to break out into a cold sweat. After all, the more it runs, the bigger the power bill at the end of the month.

In an effort to calm the nerves and put less strain on your wallet, here are five ways to make your air conditioning unit work better and save money:

  1. The top way to make your A/C unit work better and save money is to replace your filter EVERY MONTH.   Having a clogged filter in your air conditioning system slows down the flow of air, which makes the air unit work harder to cool your home. Clogged filters can even cause costly damage to the system.  Replacing filters will ensure that you have cleaner air at a lower cost, with lower risk of your AC breaking.
  2. Use household fans to help keep the house cool.  When people try to figure out how to make their AC work better to save money they often forget about this.  A fan uses significantly less energy than your AC unit.
  3. Try to pay it forward to your AC unit and protect it from the sun.  If your AC unit was placed in an area where it is in the sun most of the day, try planting shrubs or trees around it.  The cooler the AC unit, the better it will cool your home. Just make sure not to plant too close to the unit – leave enough room for proper ventilation and comfortable servicing.
  4. If you make your home drier by getting rid of humidity you will see a change in comfort right away, because your body’s natural cooling systems work better in low- humidity air.  Your AC unit removes some moisture from the air by itself ( thus, the delightful drip and drainage from the outside unit ). However, if you live in a tropical or subtropical climate with high humidity such as Richmond, a dehumidifier can ease the strain on your AC unit and keep everyone more comfortable at higher temperatures.
  5. By hanging curtains in front of the windows of your home, or thick blinds (not mini-blinds), your home will stay cooler on its own. For many a decorator,  the mere thought of insulated drapes causes a recoil and cringe reaction.  But don’t be so quick to judge. Insulated drapes have come a long way in the past few years. They come in different styles and colors now and should at least be considered if you have South facing windows.  They really do help keep the heat out in summer and the cold out in winter. Draperies keeping the heat out in the hottest part of the day can keep your air conditioning unit from working so hard.

Your heating and cooling specialists at Marshall Mechanical know additional ways to save on cooling costs, and we would be happy to help you if you have any questions. Contact us at  804-323-0189  for more information today.

How to determine if you should replace your heating and air conditioning system

Saturday, March 13th, 2010
It’s not always easy to determine if you need to replace your home’s heating and air conditioning system.  A professional HVAC engineer can work with you to determine whether fixing or replacing it is the best option.
But here are the some points to help you make your decision if you are considering replacing your HVAC system:

 ❏ Some of your rooms are too hot or cold. 

Duct problems, inadequate air sealing or insulation could be the cause. No matter how efficient your heating and cooling system is, if your home is not properly sealed and insulated against air leakage, you will not be as comfortable and your system will have to work harder.  

❏ Your home has humidity problems and/or excessive dust.  

Poorly operating or improperly sized equipment could be to blame. Leaky ductwork can also cause these problems, so having it sealed may be a solution. Monthly maintenance of your heating and cooling  equipment’s filters may also help.  

❏ Your cooling system is noisy.  

Your duct system could be improperly sized or there may be a problem with the indoor coil of your  cooling equipment.  

❏ Your equipment needs frequent repairs and your energy bills are going up.  

In addition to the rise in energy costs, the age and condition of your heating and cooling equipment may have caused it to become less efficient.  

❏ Your air conditioner or heat pump is more than 12 years old.  

Consider replacing it with newer, more efficient equipment. And, remember, high efficiency levels begin with ENERGY STAR.  

❏ Your furnace or boiler is more than 15 years old.  

Consider replacing it with ENERGY STAR® qualified equipment. ENERGY STAR has set high efficiency guidelines for both types of heating systems.  

❏ You leave your thermostat set at one constant temperature.  

You could be missing a great energy-saving opportunity. A programmable thermostat adjusts your home’s temperature at times when you’re regularly away or sleeping.  

❏ Your score on the ENERGY STAR Home Energy Yardstick is below five.  

That means you’re using more energy at home than most Americans and probably paying more than you need to on energy bills. Get personalized recommendations to improve your home and/or heating and cooling system. Find the Home Energy Yardstick at www.energystar.gov. Click on Home Energy Analysis.  

The professional HVAC engineers and technicians at Marshall Mechanical can help you determine what’s best for you, your family’s comfort and your home.  Simply call us at 804.323.0189 today.

7 Things to Look for in a Home Heating and Air Conditioning System

Tuesday, March 2nd, 2010

Purchasing a new home heating and air conditioning system is often more important than people recognize.   Not only does your HVAC system need to keep you warm in the winter and cool in the hot Richmond summer months, it needs to run at high efficiency to save you money, have noise reduction features for quiet operations and both balance air flow and keep it at the right moisture level. 

In this way, you’ll enjoy a comfortable home all year long and for many years to come.  It is truly an investment in your home that you should not rush into purchasing, just like any other investment.  Take your time, check the facts and ask questions of your HVAC contractor.

To help you make the best decisions in purchasing your new HVAC system, here are 7 things to consider:

  1. Reliability.  Chances are, your heating and cooling system is one of the most expensive pieces of equipment you will purchase for your home.  That’s why it’s important to choose proven products from a reputable manufacturer.
  2. Efficiency.  A new ENERGY STAR®-labeled system, when properly sized and installed, can save you up to 20% on your annual heating and cooling costs. Plus, it may qualify you for utility rebates and tax credits.*
  3. Quiet operation.  The sound of a standard furnace can be as loud as 100 decibels, comparable to the sound of a kitchen garbage disposal! Air conditioners can produce sounds as high as 80 decibels. Look for technologies and features that help keep operating sound at a comfortable level.
  4. Consistent temperatures.  With a typical furnace or single-speed air conditioner, indoor temperature can vary as much as seven degrees from the thermostat setting. Variable speed and/or two-stage systems give you the assurance of precise temperature control.
  5. Balanced humidity.  To maintain proper moisture levels in your home, choose a thermostat that controls both temperature and humidity. You might also consider a variable speed and/or two-stage comfort system and dehumidifier.
  6. Proper Airflow.  A typical furnace motor runs at one speed and circulates a constant volume of air, so it responds to changing comfort demands by repeatedly cycling on and off. This frequent cycling increases air stratification and stagnation. For optimal air circulation, choose a variable speed model.
  7. Healthy air.  One of the best ways to combat indoor pollution is to attach an air cleaner to your furnace or air handler. That way, you can have peace of mind knowing your system is working to capture small contaminants in every room of your home.

Here at Marshall Mechanical, we partner with Lennox because of their superior heating and air conditioning equipment and because they are the innovation leaders in high efficiency technology.  Their products are superior in many ways.  But we will always talk with our customers to find out exactly how they use their HVAC system and take into consideration their home specifications to make the best choice for each individual family and home. 

For a free consultation on what heating and air conditioning system is the best choice for you and your Richmond-area home, please call the HVAC professionals at Marshall Mechanical at 804.323.0189 today.

Your Spring Home Heating and Air Conditioning Maintenance Checklist by Lennox

Monday, February 22nd, 2010

With the early bout of warm weather in the Richmond area this weekend, it’s not too early to start planning for your HVAC system’s Spring maintenance.  As you may know, Marshall Mechanical is an authorized Lennox dealer and we specialize in helping you to maintain your heating and air conditioning equipment so that you can enjoy comfort and energy savings all year long, for many years to come.  Below is an excellent Spring HVAC maintenance checklist* and reminders to help you best maintain your HVAC equipment this year.

Keep your cool with simple A/C maintenance

  • Clear leaves, brush and dirt from inside your air conditioner’s top grille.
  • Trim nearby shrubs and bushes to allow at least two feet of clearance around the unit.
  • Set the thermostat to cooling mode and run your air conditioner a few minutes to make sure it’s working.
  • Schedule an annual checkup of your air conditioning system.
  • Replace your air conditioner filter once a month. Dirty filters restrict air flow and can waste energy.
  • If you use a room air conditioner, install it on a north-facing wall to keep it out of the sun.
  • If it’s time to replace your air conditioner, look for an ENERGY STAR® qualified model to help reduce cooling costs up to 20 percent.

 Don’t let April showers bring May mildew

  • Clear leaves, pine needles and other debris from gutters and downspouts to ensure proper drainage. Check that they’re stable to avoid flying debris during storms.
  • Be sure downspouts slope away from your house. They should carry water at least 5′ from foundation walls.
  • Position lawn sprinklers so they don’t spray your home’s walls.
  • Examine window and door seals and weatherstripping. Reseal if needed.
  • Move furniture a few inches away from the inside of exterior walls to increase air circulation.
  • Check windows for condensation and walls for water stains, which are signs of too much humidity.
  • Keep your home’s relative humidity between 30 – 50%. A humidity control system such as Humiditrol® can safely control humidity.

 Take control of home energy costs

  • Reduce air leaks in your home by caulking, sealing and weatherstripping around doors and windows.
  • Use exhaust fans to reduce moisture in the kitchen or bath, but turn them off when they’re no longer needed.
  • Make sure your refrigerator’s seals are airtight. Test by closing the door over a dollar bill. If you can pull the dollar out easily, the seal may need to be adjusted.
  • Wash only full loads in your dishwasher and clothes washer.
  • Turn off lights you don’t need to save energy and reduce extra heat in your home.
  • If it’s time to replace your air conditioner, choose an energy-efficient model with two-stage cooling, such as the XC-21.  Two levels of operation allow you to rely on the low setting most of the time and it runs at low speed 80% of the time, which means lower operating costs, more consistent comfort and better humidity control.
  • Prepare dinner on your outdoor grill to help reduce your air conditioner’s load.
  • Check ducts for air leaks, including holes or separated sections.

After having such a cold and snowy winter here in the Greater Richmond area, I think we’re all be glad that Spring is not too far around the corner.  Remember, Marshall Mechanical is uniquely qualified to handle all your HVAC maintenance needs and we can help you protect your equipment and the investment you’ve made in your home.  To schedule your Spring HVAC check-up, simply call our office at 804.323.0189 to schedule your appointment today.

Lennox Home Comfort Tip: Can you heat your house with solar power?

Wednesday, February 10th, 2010
Lennox XPG20 solar-assisted heat pump

Dave Lennox Signature® Collection XPG20 SunSource™ Comfort System

Running your home on the sun’s power is a green dream that can cost a small fortune: $30,000 or more to add a whole-home photovoltaic panel system that won’t provide enough electricity to meet most of your home’s needs. Yet a more modest solution will allow you to take advantage of the sun’s power.

Simple ways to use the sun’s power

Solar tubes or tubular skylights can light small spaces if they’re installed in areas receiving several hours of direct sunlight a day. When you choose a solar-assisted home comfort unit (heat pump), you can pair solar power with energy from your local utility to reduce your carbon footprint and lower your energy bills while staying completely comfortable. The SunSource™ Comfort System available from Lennox® is the industry’s first integrated solar-assisted heat pump.

Costing far less than complete solar-powered systems, the solar-assisted heat pump can operate in a wide range of sunlight and temperature conditions. It’s a highly reliable system designed to evenly heat and cool your entire home. The SunSource™ Comfort System requires little routine maintenance and can make a positive change in both the world’s environment…and yours.

Marshall Mechanical is your Richmond-area resource for a wide range of green and super energy efficient solutions for heating and cooling your home, including both solar and geothermal too.  Simply call our knowledgable and friendly HVAC experts at 804-323-0189 to take advantage of Lennox’s superb Solar home comfort system.
