About Virginia Air Conditioning and Heating Companies

With its proximity to the nation’s capital, Northern Virginia is a great place to live and work. World-class attractions are a stone’s throw away, and the climate, with its four distinct seasons, is hard to beat. Warm summers and chilly winters are only enjoyable, however, when you have a functioning, efficient air conditioning and heating system.

If your home’s HVAC system isn’t working quite as well as it used to, or if you’ve noticed a steady climb in your utility costs, a service visit from an experienced, reliable HVAC technician is probably in order.

Heating and air conditioning system efficiency

An efficient HVAC system is a win-win: It has less of an environmental impact than an older, inefficient unit, and it costs less to run. Both the planet and your bank account benefit.

But as air conditioners, furnaces, boilers, and other types of HVAC systems age, they lose efficiency. In some cases, an equipment retrofit can help regain some efficiency, but in others, a new system is your best bet.

If a new HVAC unit is in your near future, keep the following efficiency tips in mind as you shop and compare models:

  • Pay attention to SEER (Seasonal Energy Efficiency Ratio) ratings. If you’re purchasing a new system, look for an ENERGY STAR-rated model with a SEER rating of at least 14. Higher SEER ratings equal more efficient systems.
  • Make sure the system is correctly sized. An HVAC system that too small for your home will be forced to work harder and run more often, which will increase your utility costs and decrease the system’s lifespan.
  • Consider less traditional solutions. A ductless mini-split system, for example, may be a better, more cost-effective option for heating and cooling a basement or home addition.

Be sure to talk to your HVAC contractor about your specific needs and preferences in a new heating and air system so that they can help guide you to the best solution.

Northern Virginia HVAC system best practices

While your HVAC system’s size and SEER rating have a significant impact on its overall efficiency, how you use and maintain the system matters too.

Follow these best practices to keep your system running properly:

  • Stick to a regular maintenance schedule. The standard recommendation is two maintenance visits per year: One in the spring, before the weather gets hot, and another in the fall, before you turn on the heat.
  • Don’t forget about your air filters. Dirty furnace filters can obstruct airflow, which decreases your system’s efficiency. Replace your filters every quarter, or once a month if you have allergies or furry family members.
  • Install a programmable or smart thermostat. They really do help keep your utility costs down (assuming you set reasonable temperatures, of course), and once you set it up, your part is done.
  • Use the recommended thermostat settings. To keep your energy costs low, the US Department of Energy recommends that you keep your thermostat set at 78 degrees in warm weather and 68 degrees in cold weather.

Increasing (or maintaining) your HVAC system’s efficiency doesn’t have to involve major lifestyle changes. All it takes is a few small adjustments here and there, and the proof will show in your monthly expenses.

How to Improve HVAC Energy Efficiency

According to ENERGY STAR, a joint program of the Department of Energy and the Environmental Protection Agency, the average home is responsible for twice the greenhouse gas emissions of the average car.

Furthermore, almost half of the average household’s energy bill consists of heating and cooling costs. This fact can be alarming to the environmentally conscious homeowner. 

Fortunately, there are many things homeowners can do to reduce their heating-and-cooling energy consumption and, consequently, their environmental impact.

HVAC Maintenance

The leading cause of HVAC inefficiency is simple dirt and disrepair. Homeowners should inspect their filter after every month of heavy use and change it when necessary. They should also schedule a professional maintenance check annually.

These precautions will keep the system running as efficiently as possible for the longest amount of time.

HVAC Equipment

No matter how well-maintained your HVAC system is, it will only be as efficient as its capabilities allow. Generally speaking, the older the system, the less efficient it is.

Currently, the government requires air conditioning systems to have a minimum SEER (Seasonal Energy Efficiency Ratio) of 13. Many older units, however, operate at 10 or even 8 SEER. 

Most professionals recommend that homeowners invest in a high-efficiency system if they plan on staying in their home for at least six years. In terms of heating, high-efficiency gas furnaces tend to work at a low level throughout the day, as opposed to working for bouts at a high level.

This keeps the temperature relatively constant throughout the day, leading to lower energy use and increased comfort.

Programmable Thermostats

To get the most out of your programmable thermostat, make sure that it’s installed away from sources of heat or cold, including registers, fireplaces, lighting, and areas that are drafty or receive direct sunlight. 

Also, if you have multiple heating and cooling zones, it’s best to use a different thermostat for each zone. This will prevent your system from performing unnecessary work.

Your Home's "Envelope"

Your home’s “envelope” is the entirety of its exterior—windows, walls, ceiling, and floor. According to ENERGY STAR, you can save up to 20 percent on your heating and cooling costs by sealing your home’s envelope.

This might include adding insulation to the attic, replacing windows, or sealing air leaks in the ductwork. Consider hiring a certified Home Energy Rater to conduct an evaluation of your home.

Besides reducing your energy bill and environmental impact, an efficient heating and cooling system will increase the overall comfort level of your home.

Consult an HVAC professional for more information on energy-efficient HVAC systems and to determine if one is right for you.
