Benefits of Furnace Replacement

Snow, sleet, and ice are not uncommon during Maryland winters, so you’ll want to make sure your furnace is prepared to handle the coldest of nights and keep you cozy all winter long. When you choose to install a new furnace, you’ll notice an overall improvement of the air quality in your home. Other benefits include:

  • Improved energy efficiency – New technology, particularly Bryant® furnaces, have a higher AFUE rating. This means new a new furnace installed in your home will convert more fuel directly into heat, resulting in lower monthly energy bills.
  • Reduced repairs – If you’ve repaired your furnace more than once in the past two years, it’s time to consider furnace installation. Furnace repairs should be few and far between if your heating system is maintained properly. So, installing a new furnace will reduce the number of service calls and keep your money where it belongs—in your pocket!
  • Lowered home energy bills – After installing a more energy efficient furnace, your home heating system will use less energy to heat your home, ultimately lowering your energy bills.
  • Improved comfort – A new furnace is better at producing consistent temperatures in your home and from room to room. New models also operate quieter than older, louder furnaces.

Furnace FAQs

  • Can a homeowner install their own gas furnace? A furnace installation, and especially in the case of a gas furnace, requires a very specific set of tools and knowledge. Without a professional installation, you risk not only wasting a lot of money, but also potential health and home risks.
  • How long does it take to put in a new furnace? The answer will differ slightly according to the system and home in question, but in most cases, a new installation project can be completed within a day, sometimes two.
  • How long does a gas furnace usually last? When properly maintained a gas furnace should last a minimum of 15 years—20 or more with professional service.
  • How much does it cost to replace a furnace? Furnace prices fall within a rather wide range, depending on the technology and efficiency.
  • Should I repair or replace my furnace? Generally, speaking if the system is too old, or if the cost of repair equals a third of the cost of the system itself, it is time to replace.
