The decision depends on your system's age, repair cost, and overall condition. General guidelines: If your heating system is under 10 years old and repair costs less than 30% of replacement cost, repair is usually best. If it's 15+ years old, experiencing frequent breakdowns, and repair costs exceed 50% of replacement, investing in a new energy-efficient system often makes more financial sense. Our technicians provide honest advice—we never pressure you into unnecessary replacements. We'll explain your options, show you the numbers, and help you make the best decision for your home and budget.

Preventive maintenance is the best way to avoid heating breakdowns. We recommend annual heating system tune-ups every fall before winter arrives. During a tune-up, we clean burners and heat exchangers, test safety controls, check for carbon monoxide leaks, lubricate moving parts, test ignition systems, inspect electrical connections, and ensure proper airflow. Annual maintenance prevents 80-95% of breakdowns, extends equipment lifespan by 5-10 years, maintains energy efficiency (saving 10-30% on heating bills), and keeps manufacturer warranties valid. Additionally, change your filter every 1-3 months, keep vents clear, and address strange noises or performance issues immediately.

It depends on the problem. Some issues are merely inconvenient while others pose serious safety risks. Turn off your heating system immediately and call for repair if you: smell gas (evacuate and call 911 first), see yellow or flickering flames (carbon monoxide risk), hear loud banging or booming (delayed ignition—can crack heat exchanger), experience carbon monoxide detector alerts (evacuate immediately), or notice excessive condensation or rust on your furnace (potential heat exchanger crack). For less urgent issues like weak heat or strange noises, you can often safely operate the system at reduced capacity until repair, but don't delay professional service.
