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

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.
