How Will I Know When to Replace My Furnace?

It’s not always easy to tell if your furnace is starting to fail. However, your heating system can start to give you some signs that it’s close to wearing out. Here are several of the most common signs of needing furnace installation:

  1. It’s close to 20 years old.
  2. You’re scheduling repairs more often.
  3. Decreased comfort, but increasing energy bills.
  4. Yellow burner flames, indicating carbon monoxide.

Newer furnaces are more efficient at converting fuel into heat; a high efficiency furnace with a 95% AFUE rating translates to significant savings over its lifetime!

Should I Install a New Heater?

Modern industrial engineers typically use predetermined motion time system, computer simulation, along with extensive mathematical tools for modeling, such as mathematical optimization and queueing theory, and computational methods for system analysis, evaluation, and optimization.

Taking the Old Heater Out

Sure, this sounds like a simple step! But you may be unpleasantly surprised to learn that this is actually the most laborious part of the process, and in most cases, the lengthiest. It’s about more than simply pulling out the old heating system. If this system is connected to your gas line already, for instance, our technicians have to ensure nothing is damaged or knocked out of place when we remove it.

We also need to check that the furnace is properly sized for the space in which it’s being installed. No, we don’t just mean that the furnace must slide into place—we mean that the furnace system must not be overpowered or underpowered. This requires us taking a heat load calculation, and without this, you can be stuck with a highly inefficient furnace.

Making the Connections

Once the new furnace has been installed, and usually, this means bolting it to the floor, too, our technicians will connect the system to the components needed for its operation.

This includes your ventilation system, or, your ductwork. Ductwork must be hooked up to the furnace correctly in order to avoid damaging them. Air ducts often have to be adjusted and shifted during this process, and this is where mistakes can happen if not handled carefully.

Next, our techs hook your furnace up to its power source. As we mentioned above, we have your safety to contend with when it comes to gas-powered furnaces. Any connections to your gas line require an experienced and specially licensed professional to manage.

Last, is the wiring. Even gas-powered heating systems do have some electrical wiring. With the potential for a fire hazard if this step isn’t done correctly, it’s easy to see why you should only trust a trained and experienced heating installer.

Testing Your New Heating System

Testing your furnace is the final step, but certainly not the least important. If our techs left your home after making the last connection without testing your new heating system, you’d have no way of knowing if your furnace was working as efficiently as it was supposed to, or as safely as it’s meant to!

Our pros will turn on your furnace, measuring the intake and airflow, to ensure that the performance is efficient and safe.


It’s often less expensive to replace your furnace and air conditioner at the same time. Plus, you’ll also enjoy greater energy efficiency year-round. Here’s when you should replace both systems at the same time:

  • Your heater and air conditioner are more than 15 years old.
  • You want to install a high-efficiency air conditioner soon, which might not be compatible with an older model.
  • You want to boost your energy savings with a smart thermostat, which often don’t work with older heating and cooling equipment.
  • Installation is difficult.
  • You don’t want to have to worry about heating and cooling repairs in the next few years.
