- Strange noises like banging, rattling, or whistling

Gas Furnace Diagnostics, Repairs & Restored Comfort
When you schedule a gas furnace repair with Koontz Heating & Air, we start with careful diagnostics to identify the root cause—not just the symptom. During service, our technician may inspect and test:
- Ignition system (pilot, hot surface igniter, or spark ignition)
- Burners, flame sensor, and gas valve operation
- Blower assembly and airflow performance
- Thermostat communication and controls
- Safety switches and operating limits
- Venting and combustion-related components
Before we leave, we confirm safe operation, verify proper heating output, and answer any questions you have about your system’s performance.
Repair vs. Replace: When Is a New Furnace the Better Choice?
Not every furnace issue requires replacement—but there are times when upgrading makes more sense. Our team will give you an honest recommendation if we believe replacement is the smarter long-term investment. You may want to consider replacement if:
- Your furnace is older and requires frequent repairs
- Repair costs are rising or involve major components
- Comfort is inconsistent throughout the home
- Efficiency is declining and bills are climbing
- There are safety concerns related to combustion components
If replacement is the right option, we’ll help you choose the best system for your home with accurate sizing and a professional installation plan.
Prevent Breakdowns with Annual Furnace Maintenance
Many emergency repairs can be avoided with preventive service. Annual furnace tune-ups help your system run efficiently, reduce wear and tear, and catch small issues before they turn into major breakdowns. If you want fewer surprises and more reliable comfort, ask our team about scheduling maintenance.

Frequently Asked Questions
Is a gas furnace blowing cool air always a repair issue?
Not always—sometimes it’s a thermostat setting or airflow problem. However, it can also indicate ignition issues, burner problems, or safety shutdowns. A professional diagnostic is the best way to confirm the cause.
What should I do if I smell gas near my furnace?
Leave the area immediately and follow your gas utility’s safety guidance. If it’s safe to do so, shut off the gas supply and contact your gas provider. Once the immediate safety concern is addressed, schedule service for inspection and repair.
Why is my furnace turning on and off so frequently?
Short cycling can be caused by restricted airflow (dirty filter), thermostat problems, overheating, or faulty sensors. It should be addressed quickly to prevent increased wear on the system.
How long does a typical gas furnace repair take?
Many repairs can be completed in a single visit. The timeline depends on the issue, system accessibility, and whether parts are needed.
Can I run my furnace if it’s making loud noises?
Loud noises can indicate loose components, blower issues, ignition problems, or other mechanical faults. Continuing to run the system may worsen damage—schedule service as soon as possible.

Yes. Koontz Heating & Air offers 24/7 emergency service so you can get help when you need it most.
