Call to Schedule →Is Your Key Largo Furnace Showing These Warning Signs?
Furnaces give warning signs before they fail completely. If your Key Largo system is doing any of these, a same-day diagnostic can prevent a full breakdown mid-winter.
- →Error code flashing on the panel — we decode it, find the root cause, and repair the actual failed component
- →Furnace shuts off before the house warms up — high-limit switch tripping due to restricted airflow
- →Gas smell near the furnace — shut off gas, leave the building, and call from outside immediately
- →Condensate drain backing up — (high-efficiency) clogged line trips the safety float switch and shuts system down
- →Inducer motor making a high-pitched squeal — bearing failure; if it fails, the furnace won't start at all
- →House stays cold even with furnace running all day — duct leakage, failing heat exchanger, or wrong system size
- →Carbon monoxide detector going off — leave the building, call 911, then call us after the space is cleared
- →Furnace over 15 years old with repeated repairs — if repair costs exceed 50% of replacement, a new system wins

Frequently Asked Questions — Furnace Repair in Key Largo
Yes. Upgrading from 80% to 96% AFUE reduces fuel use by roughly 16%. Most homeowners see a clear savings difference within one winter.
You can — but ensure each company runs a real diagnostic first. Price differences often reflect different diagnoses, not just different rates.
If a part isn't on the truck, we order it immediately and schedule the earliest available date — usually the next business day.
No. Turn it off, leave the home, and call your gas company from outside. Once cleared, we inspect the combustion system.
The draft inducer vents combustion gases and creates the airflow needed for safe ignition. If it fails, the furnace won't light at all.
Yes — condensate drains and PVC intake pipes can ice over in severe cold, causing shutdown. We clear and repair these issues same-day.
Burning plastic usually means melting wire insulation or a failing component. Turn off the furnace and call us — don't let it keep running.
Look for state HVAC licensing, NATE certification, and manufacturer training. Our Florida technicians meet all these standards.
