Should I Repair or Replace My Furnace?

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

Furnace Age

Furnaces usually last about 12–17 years. If yours is 15 years old (or more), there is a higher risk of breaking down. You should start to prepare for replacement by researching new furnaces promptly.

Constant Repairs

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

Higher Energy Bills

Old furnaces are less efficient. If yours hasn’t undergone yearly furnace maintenance, you risk losing additional furnace efficiency and dealing with higher energy costs.

Weak Heating

An old furnace can struggle to properly heat your home. Leaky ductwork and a clogged furnace filter can also cause issues.

Three Benefits of a New Furnace

While furnace installation can feel intimidating, new furnaces can boast efficiency worn down systems can’t contend with. Additionally, you’ll be able to relax knowing you don’t need to replace your system for a long time.

A new furnace should provide:

1. Increased Efficiency

New furnaces are very resilient and can boast exceptionally better efficiency ratings compared to equipment from 20 years ago.

2. Less Noise During Operation

A newer furnace includes the latest in quiet operation technology. You may not even notice when it turns on.

3. Peace of Mind

The latest HVAC technology ensures your furnace will live longer and run with greater energy efficiency. With our service agreements, you’ll never forget an important annual tune-up again.

Furnace Installation FAQs

Proper sizing is based on factors like home size, insulation levels, window efficiency, ceiling height, and regional weather. Many contractors use a Manual J-style calculation to avoid problems caused by undersizing, such as short cycling.
Many installations are completed in one visit, but timing can vary depending on venting changes, utility connections, permits and inspections, and whether you’re upgrading equipment. Your installer should provide a clear schedule 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 clear a path to the furnace, keep pets in another room, and have someone available for questions. After installation, the team should verify safety controls, review system settings, and explain maintenance needs.
A newer furnace can improve efficiency, but savings depend on your current equipment condition, temperature settings, air leaks, and overall heat loss. A technician can help you compare efficiency ratings and expected performance for your home.
