Is It Time to Purchase a New Furnace?

Your unit will always signal when it’s time to replace a furnace. The signs of this are subtle, and if you’re not paying attention, you may miss them. To help you understand your system, we’ve listed six common signs that your system needs to be replaced.

1. System Age

If your furnace isn’t working properly, it could be on its last leg. On average, the lifecycle of a furnace is just over 10 years. This, of course, will depend on how often you use and service your system.

If you’re not sure how old your furnace is, locate your unit’s model number or owner’s manual. It should have the information you need.

2. Built-Up Dirt

Excessive amounts of dander, dirt, and soot can clog your system and impact its function. If you’ve recently had your unit serviced by a professional HVAC technician and it is still malfunctioning, it’s likely time to replace your furnace.

3. Low Humidity

If the air in your home feels dry and irritates your skin, this is an indicator you may need to replace your furnace. Colder seasons will naturally cause the air to be drier than in warmer seasons but a furnace will only worsen your indoor humidity levels. Homes with hardwood floors will have even more difficulty maintaining comfortable humidity levels. To keep your home warm and maintain correct humidity, contact an HVAC technician for an evaluation.

4. Uneven Heating

A fully functioning furnace should always warm your home evenly. However, as your system ages, your unit will naturally decrease in efficiency. One indication of this is a furnace that doesn’t blow air through your home’s ventilation system.

5. Noisy Furnace

A normal furnace will quietly hum and blow air throughout a normal cycle. If your unit is making loud rattling or buzzing sounds, this is a sign you may be required to replace your furnace. To prevent a gas leak and other issues, you will need to contact a licensed technician to inspect your heating system. If the issues in your system cannot be fixed, a professional will help you find a new furnace that is the correct capacity for your living space.

6. Rust & Cracks in the System

Over time, your furnace will naturally deteriorate. Cracked and rusty components will be the initial telltale signs that it is time to replace your unit.

What’s the Differences Between Conventional & Condensing Gas Furnaces?

Conventional Furnaces

These systems are older and use traditional components of a furnace: natural gas, chimney flue, pilot, and a spark.

Condensing Furnaces

These systems are extremely efficient and produce heat after the burner has stopped igniting. This is done using primary and secondary heat exchangers.

What Are the Different Types of Furnaces?

Within the condensing and conventional types of furnaces, there are three subcategories of air warming systems. These stages refer to the technology and sophistication that are in control of the blower and burner.

Single-Stage Furnace

This is the most economical furnace option. Both components of the single-stage furnace (burner and blower) have one function: on.

Two-Stage Furnace

Replace your old single-stage system with an efficient two-stage furnace. This type of furnace has two electronic controls, which allow the flame and burner to simultaneously be at a low and high setting.

Modulating Furnace

The final type of furnace manages the blower motor and burner, which allow small adjustments to the burner setting, motor speed, and overall room temperature.
