Furnace Repair FAQ
Is it cheaper to repair or replace a heater?
This is a critical question. While a repair is generally less expensive immediately, replacement may be the smarter long-term financial decision if:
- Your furnace is 15 years old or older and facing a major breakdown.
- The repair cost exceeds 50% of the cost of a new system. This is often called the "50% rule."
- Your heating bills are constantly rising, indicating the unit is highly inefficient.
What are the most common furnace repairs?
In our experience, the most common issues we address during a heating system repair include:
- Ignition System Failures: Problems with the pilot light or electronic ignitor that prevent the burner from starting.
- Malfunctioning Thermostats or Control Boards: Issues that prevent the furnace from receiving the proper commands to turn on or off.
- Blower Motor Issues: Problems with the motor that moves air through your ducts, leading to weak or no airflow.
- Clogged Filters: While an easy fix, a severely clogged filter can lead to overheating and other component failures.
Why isn't my heating system heating my home?
If your system is not heating properly (blowing cold air, producing weak heat, or not running at all), there are several likely culprits. The issue could be related to:
- Ignition Problems: The furnace is running, but the burner isn't lighting.
- Thermostat Error: The thermostat is set incorrectly or has a wiring issue.
- Dirty Filter: Restricted airflow can cause the system to overheat and shut down (short cycle).
- Ductwork Leaks: If your ducts are leaking, the heat is escaping into unconditioned areas (like the attic) before it reaches your rooms.
How much does it cost to repair a central heating system?
We believe in upfront pricing with no surprises. The final cost depends entirely on the specific part that needs replacement and the complexity of the repair. When you call us, we will clearly explain any diagnostic or service fees before we dispatch a technician. Once we are on-site, we diagnose the issue and provide you with a detailed, fixed-price quote for the repair itself.
What is the life expectancy of a furnace?
The typical life expectancy of a well-maintained modern furnace is 15 to 20 years. However, this lifespan can be significantly shortened by poor maintenance, inconsistent use, or improper installation. Enrolling in our preventative maintenance plan is the best way to maximize the longevity and efficiency of your unit.
How long will my heating system repair take?
The duration of the repair depends entirely on the complexity of the issue. A simple fix, like replacing a flame sensor, can take less than an hour. A more complex component replacement may take a few hours. Because we offer same-day or next-day service whenever possible, we work quickly to diagnose the issue and complete the job on the first visit so your home comfort is restored fast.
