When to Repair or Replace Your Furnace

If your heater is more than 15 years old, frequently breaks down, or has rising energy bills, replacement may be the smarter investment.


We’ll provide an honest assessment and help you decide whether to repair or upgrade. Our goal is always to fix your current system if possible — but if replacement makes more sense, we’ll guide you through your options for a new, high-efficiency model.
