Determining the Best Furnace for Your MD or VA Home

Before you decide which type of heating system is right for you and your family, take a minute to consider a few points that can help you choose the best furnace to meet your needs.

  • Your home and unit’s size. Having a furnace that’s too small can mean insufficient heat during the middle of the cold weather season. However, purchasing a furnace that’s too big can also shorten the lifespan of your system. A good HVAC contractor can help you determine the correct size furnace for your home.
  • The system’s energy-efficiency rating. All new furnaces and heating systems are marked with an annual fuel utilization efficiency (AFUE) ratio. Most furnaces built in the 1970s have an AFUE ratio of around 65. Today, the lowest ratio allowed by law is 78. At Bonsby HVAC & Plumbing, we offer systems with near perfect efficiency ratios of 90 or more. Generally, you’ll pay more for your new furnace the higher the AFUE ratio, but it can pay for itself in the long run with lower monthly heating bills.
  • Warranty. A new furnace is a major investment. You want the system to be protected should something go wrong after you buy it. Most furnaces come with a limited warranty. Common terms are 20 years for the heat exchanger and five years for other mechanical parts, but we can provide you with specifics based on the unit you choose.

Residential Heating Systems

At Michael Bonsby HVAC & Plumbing, we recommend natural gas furnaces for their ability to provide optimal heat production and energy efficiency. Plus, they tend to have longer life spans and cleaner operation with less maintenance than other heating systems. The various models of gas furnaces include:

  • The single-stage furnace is the least expensive option for those replacing their heating systems on a budget, however it also only has one “on” stage for the burner and blower. This means that you may not receive the optimal level of heat that you can with other types of gas furnaces.
  • The two stage furnace, also known as the dual stage furnace, has greater capacity to heat in different settings and can be set to high, low, or off. They are slightly more expensive, but they also are known to provide quieter operation.
  • The modulating furnace provides the most accurate temperature reading of all the models, so you can rely on the thermostat to be pretty precise. It supplies the most comfort of all furnaces as well, which is ideal for especially cold periods, and tends to be the most efficient. However, installation costs are higher.

The best furnaces can last you 15 years or longer and slash your heating bills for greater comfort at a fraction of the price. At Michael Bonsby HVAC & Plumbing, we offer a range of high quality systems from leading brands like Mitsubishi and American Standard and have been helping residents of the Maryland and DC areas with the selection and installation process for over 20 years.
