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.

8 signs that you may need to service or replace your HVAC system

Monday, January 18th, 2010

Is the air quality and temperature in your Richmond home or office less than you would like it to be? Lennox, one of our trusted manufacturers of heating, cooling, and air purification systems, offers the following information to help you improve your air — and save money doing it.

If you’re experiencing any of the problems on this checklist, you might want to consider making a change.  Take a look:

  1. 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.
  2. 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.
  3. 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.
  4. 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.
  5. Dave Lennox Signature® Collection XP19 Heat Pump, the most quiet and efficient heat pump you can buy

    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.

  6. 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.
  7. 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, and then brings it back to your preferred temperature for times that you are awake and doing things in the house.
  8. 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.

If any of these apply to you, consider calling us for a consultation with one of our certified HVAC experts today at 804.323.0189Marshall Mechanical is a certified dealer of Lennox and our experts can help you find exactly the right solution for your home or commercial building.

HVAC engineers keep you comfortable, no matter the weather.

Tuesday, August 25th, 2009
Staying comfy? Thank an HVAC Engineer.

Staying comfy? Thank an HVAC Engineer.

Just ran across this Washington Post article by Roger K. Lewis, an architect and professor at the University of Maryland, talking about the challenges we go through in order to keep indoor climates safe and comfortable.  “Properly conditioning building interiors,” he says, “also means taking care of humidity, unseen condensation, mold and mildew, indoor air quality, acoustics and air drafts, not to mention energy conservation.  Thus, sustainability creating comfortable, healthy interiors entails multiple, often contradictory, demands.”

He’s right.  Temperature regulation is only one small part of what HVAC (heating, ventilation and cooling) engineers have to worry about.  Roger goes on to say, “Beyond regulating temperature and humidity, an effective HVAC system helps achieve favorable, year-round air quality by continuously introducing fresh air while keeping out particulate matter and other toxic pollutants.”

Maintaining humidity levels, filtering air, managing noise from system vibrations, and draft levels are all things us HVAC engineers are concerned about.  That’s why when homeowners are in a rush because their air conditioning system isn’t working, for example, we provide an immediate solution like a window air conditioner in order to give us time to take into consideration all the aspects of the environment to engineer and install the right system that will provide lasting comfort for years to come. 

This is especially true these days when energy efficiency and green building technology are so critically important.   Solar and geothermal heat pumps, for example, are being used much more than ever before because of their ability to not only save on monthly energy costs but significantly reduce the carbon footprint for both homes and commercial buildings. 

Designing a home or building and engineering it with the new HVAC energy efficient HVAC technologies requires solar and geothermal expertise.  At Marshall Mechanical, we are your Richmond heating & air conditioning contactor and engineering experts.  We recently installed the first solar assisted heat pump in central Virginia right here in Richmond and we also successfully completed the geothermal installation for the Caroline Family Practice Health Center in Bowling Green, VA.  For all your HVAC engineering needs, both residential and commercial, call professional engineer Sean Cantrell at 804.323.0189.

You can’t control the Richmond VA summer heat but you CAN control your energy costs.

Monday, June 22nd, 2009

With temperatures rising and energy costs continuing to soar, there are a variety of steps you can take to cut the expenses of cooling your home this summer.

“Cooling and heating equipment use more energy than any other appliance. This inevitably shows up every month on the energy bill, but it’s important to remember that energy costs can be controlled,” said Sean Cantrell, owner of Marshall Mechanical.

Annual Maintenance

One step to control energy costs is to schedule annual maintenance checks to make sure your unit is running efficiently. Most cooling systems require very little owner maintenance. However, operating dirty cooling equipment can result in an unnecessary loss of efficiency and can damage the furnace. You play a vital role in making sure your cooling system continues to operate at peak performance.

High Efficiency Cooling Equipment

If you’re in the market for a new cooling unit, consider purchasing a high efficiency model. They can help reduce your energy costs as well as conserve our natural resources. When selecting an air conditioner or heat pump, pay close attention to the SEER (Seasonal Energy Efficiency Ratio). This is a measure of cooling efficiency for air conditioners. The higher the SEER, the higher the savings. The minimum SEER rating is 13.

Zoning

Zoning can drastically lower your heating costs. With zoning, you no longer have to pay to heat or cool areas of your home that are rarely used. You won’t have to heat or cool the whole house just to make one room comfortable. Zoning divides your home into separate comfort areas, which are heated or cooled based on your needs.

Programmable Thermostats

Programmable or setback thermostats can make a big difference in energy consumption. These thermostats deliver maximum comfort, efficiency, and energy savings. Setback thermostats are used to achieve the temperatures you want throughout your home. For example, if you’re going to be away, you can set the whole house at an energy-saving temperature to avoid heating an empty house. If you have setback thermostats, you can program them to have your living areas comfortable when you arrive home.

To find out more about reducing your Richmond VA cooling costs, call Sean Cantrell or Mike Smith at Marshall Mechanical today at 804.323.0189.
