Should I Repair or Replace My Furnace?

While no one can predict exactly when your furnace will break down, there are some signs that your furnace has to be replaced.

Furnace Age

Furnaces usually last around 12–17 years. If yours is 15 years old (or older), you have a greater possibility of breaking down. You should start to prepare for replacement by learning more about new furnaces now.

Constant Repairs

You should think about HVAC replacement if a furnace needs repairs more often.

Increased Energy Bills

Older furnaces won’t be as efficient. If you’ve put off yearly furnace maintenance, you’re vulnerable to losing further furnace efficiency and having steeper energy costs.

Inconsistent Heating

An aging HVAC system can do a poor job at heating your home. Bad ductwork and a clogged furnace filter can also lead to problems.

Three Benefits of a New Furnace

While furnace installation can feel overwhelming, new furnaces offer benefits worn down systems can’t contend with. In addition, you can sit back and relax knowing you won’t have to replace your system for a long time.

A new furnace could mean:

1. Better Efficiency

New furnaces are highly reliable and offer exceptionally better efficiency ratings than furnaces from 20 years ago.

2. Quieter Operation

A newer furnace includes the latest in quiet operation technology. You won’t always notice when it turns on.

3. Peace of Mind

Innovative HVAC technology ensures your furnace will stay in good shape for longer and run with greater energy efficiency. With one of our service agreements, you’ll never lose out on an important furnace tune-up again.

FAQ: Furnace Installation

Proper sizing is based on factors like square footage, insulation levels, air leakage, ceiling height, and local climate. Many contractors use a load calculation to avoid problems caused by oversizing, such as uneven comfort.
Many installations are completed in a single day, but timing can vary depending on venting changes, electrical or gas updates, local requirements, and whether you’re upgrading equipment. Your installer should provide a project timeline before work begins.
Sometimes your existing thermostat works fine, but upgrades may be recommended for better control—especially with modulating systems or advanced features. Your contractor can confirm wiring compatibility and recommend the best option.
Before the appointment, it helps to make the mechanical area accessible, secure pets, and make sure the thermostat is easy to reach. After installation, the team should verify safety controls, show you how to use it, and explain maintenance needs.
A newer furnace can improve efficiency, but savings depend on your current equipment condition, thermostat habits, air leaks, and home insulation. A technician can help you compare efficiency ratings and expected performance for your home.
