Should I Repair or Replace My Furnace?

While it’s impossible to predict just when your furnace will go out, there are a couple of clues that a furnace needs to be replaced.

How Old Your Furnace Is

Heating systems usually last between 12–17 years. If yours is 15 years old (or older), there is a higher possibility of breaking down. You should start to prepare for replacement by learning more about new furnaces now.

Frequent Repairs

You should think about HVAC installation if the heating needs repairs more frequently.

Larger Energy Bills

Older furnaces won’t be as efficient. If you haven’t scheduled yearly furnace maintenance, you’re vulnerable to losing further furnace efficiency and ending up with increasing energy costs.

Spotty Heating

An older heater can struggle to keep up with heating your home. Broken ductwork and a clogged furnace filter can also stir up trouble.

Three Benefits of a New Furnace

While furnace installation sounds daunting, new furnaces offer benefits worn down systems can’t contend with. In addition, you can relax knowing you won’t need to replace your system for years to come.

A new furnace should provide:

1. Increased Efficiency

New furnaces are very resilient and provide exceptionally better efficiency ratings than models from 20 years ago.

2. Quieter Operation

Modern furnaces offer the latest in quiet operation technology. You might not notice when it starts running.

3. Peace of Mind

Modern HVAC technology ensures your heating will last longer and run with greater energy efficiency. With our service agreements, you’ll never lose out on an important furnace tune-up again.

Frequently Asked Questions: Furnace Installation

Proper sizing is based on factors like home size, building envelope, air leakage, layout, and regional weather. Many contractors use a load calculation to avoid problems caused by oversizing, such as short cycling.
Many installations are completed in a single day, but timing can vary depending on ductwork modifications, electrical or gas updates, permits and inspections, 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 variable-speed blowers. Your contractor can confirm control requirements and recommend the best option.
Before the appointment, it helps to clear a path to the furnace, keep pets in another room, 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 how old your system is, thermostat habits, ductwork condition, and overall heat loss. A technician can help you compare efficiency ratings and expected performance for your home.
