An HVAC system tends to break down at the most inconvenient times. Fortunately, many times the solution when a furnace is not working properly is simple and cost-effective, such as replacing the dirty furnace filter inside the unit. When those simple fixes and tune-ups don’t work, however, it could be time to contact a trusted HVAC contractor to help you decide if either professional furnace repair or furnace replacement services are for you.

Is it time to upgrade to a new furnace? Ask yourself the following questions:

  • Is your current furnace over 13 years old?
  • Do you frequently have high energy bills?
  • Are there obvious temperature fluctuations inside your home?
  • If you have a gas furnace, are your furnace flames no longer blue, but yellow?
  • Are you frequently shelling out money for numerous furnace repair services (more than two to three times on a single unit)?

If you answered “yes!” to any of these questions, then yes it’s time to replace your old furnace!

Considerations for Furnace Replacement and Installation

Looking for a new system to replace your old one? Keep the following factors in mind.

1. Check the size – Make sure the size of the unit is proportionate to the size of the area, in square footage, that you are trying to heat.

2. Inspect the blower motor specs – Weigh the benefits of a furnace containing a high efficiency, variable speed, and standard speed motor.

3. Choose a new unit with the right heat settings – Access the benefits of a single-stage, dual-stage, or modulating furnace.

4. Mind short-term and long-term furnace costs – Determine if the short-term expenses like labor costs and installation costs are worth more than the long-term energy savings when considering an efficient furnace to a standard furnace.

5. Don’t forget the savings – Check rebates available in the St. Louis and St. Charles areas. You can check for savings from the local government, energy companies like Ameren and Spire, and even your furnace’s manufacturer and tax incentives.

6. Keep your furnace type in mind – Know what type of furnace (natural gas furnace or electric furnace) you have now and whether you have access to natural gas lines.

Natural Gas Furnace Installation vs Electric Furnace Installation—Which is Right for You?

You have two primary types of furnaces to choose from in the St. Louis area: natural gas and electric. Most homes in the St. Louis area run on natural gas, although electric furnaces are becoming more and more popular. If you cannot decide between a gas or electric home heating system, the following points may help you make a more educated decision on which is best for you.


Gas furnaces are incredibly popular for their ease of use, effectiveness, and long-term costs. They require more maintenance and produce more noise than electric units, however, and also pose the risk of gas leaks and more pieces to fail.


  • Lower energy costs
  • Up to 20-year lifespan
  • Higher heating efficiency
  • More effective at colder temps


  • Equipment is more expensive upfront
  • Carbon monoxide concerns
  • Requires regular maintenance
  • Produces more noise


Properly maintained electric furnaces can outlive most gas-powered furnaces, cost less upfront, and give homeowners peace of mind that gas leaks aren’t a safety concern. They are, however, more costly in colder temperatures than their gas-powered alternatives.


  • Equipment is less expensive upfront
  • Requires less maintenance
  • Up to 30-year lifespan
  • Produces less noise


  • Less effective at colder temps
  • Lower heating efficiency
  • Higher energy costs
