The Answers to Your FAQ's

Frequently Asked Questions – Furnace Repair & Maintenance in Barrington, IL

Some common signs that your furnace may need professional attention include:

  • Cool or weak airflow
  • Unusual noises like rattling, banging, or whistling
  • Inconsistent room temperatures
  • Short cycling (frequent on/off patterns)
  • A yellow pilot light instead of blue
  • A sudden spike in your energy bill

If your furnace shows any of these symptoms, it's best to schedule a diagnostic with RJ's Heating, Cooling & Water Heaters before the issue becomes worse or leads to a full breakdown.

First, check your thermostat settings, furnace switch, and circuit breaker. If everything seems normal, the issue may involve the ignition system, gas supply, or internal safety switches. Call RJ's for emergency furnace repair in Barrington, IL—we'll quickly diagnose the problem and get your heat back on.

Yes! Our technicians are trained to repair all major furnace brands, including:

  • Armstrong Air
  • Ducane
  • Trane
  • Carrier
  • Goodman
  • Rheem
  • Lennox
  • York
  • MagicPak

Whether your system is newer or over a decade old, we can fix it or recommend an efficient replacement if needed.

A standard furnace maintenance visit includes:

  • Cleaning and inspecting the burner assembly
  • Testing the flame sensor and ignitor
  • Inspecting the heat exchanger for cracks
  • Lubricating motors and blower components
  • Checking and tightening electrical connections
  • Inspecting and replacing air filters if needed
  • Calibrating the thermostat
  • Testing gas pressure, startup sequence, and system shutdown

This full-system check helps ensure safe operation, consistent heating, and maximum energy efficiency.

We recommend scheduling annual furnace maintenance in the fall, before peak heating season. This helps catch minor issues before they lead to major failures and keeps your system ready for heavy use during winter in Barrington, IL.

Yes—especially for gas furnaces. Regular tune-ups help:

  • Reduce utility bills
  • Prevent costly repairs
  • Ensure safe operation (CO testing & exhaust)
  • Extend equipment life
  • Maintain manufacturer warranties

Neglecting maintenance can lead to performance issues, breakdowns, and voided warranties.

Short cycling occurs when the furnace turns on and off frequently, often before reaching the set temperature. It can be caused by clogged filters, a malfunctioning thermostat, oversized equipment, or heat exchanger issues. Left unresolved, it increases wear on components and leads to higher energy use.

Repair costs vary based on the issue. Minor fixes like replacing a flame sensor or capacitor can be affordable, while major repairs involving a blower motor, gas valve, or control board may cost more. We provide upfront pricing and transparent repair estimates before performing any work.

Absolutely. A clogged filter restricts airflow, which causes the system to overheat and puts strain on the blower motor. This can lead to short cycling, premature wear, or shutdowns. We recommend checking your filter monthly and replacing it every 1–3 months depending on use.

Banging sounds can be caused by dirty burners, ignition delays, or expanding ducts. If it happens when the furnace starts up, it may be a delayed ignition, which can be dangerous. Schedule a service appointment to ensure your system is operating safely.

Yes. Homeowners should:

  • Replace filters regularly
  • Keep the area around the furnace clear
  • Monitor for strange smells or noises
  • Check that vents and registers are unobstructed

Still, nothing replaces the value of a professional tune-up for safety and performance.

If your system is outdated and parts are hard to source, our technicians will explain your options. We never push unnecessary replacements, but we will recommend modern, energy-efficient systems if repairs are no longer cost-effective or safe.

Yes! Our Comfort Club Maintenance Plan includes:

  • Two precision tune-ups (heating + cooling)
  • Priority repair scheduling
  • Discounts on parts and labor
  • System performance evaluations

This plan is ideal for keeping your furnace running efficiently and avoiding costly emergency repairs.
