Frequently Asked Questions

  • How much does furnace repair cost in Bel Air?

    It depends on the issue. Minor fixes like ignitor replacements or thermostat malfunctions are more affordable, while blower or control board repairs may cost more. We’ll diagnose the problem and provide a clear quote before any work begins.

  • How often should I schedule furnace maintenance?

    We recommend a full furnace tune-up once per year—typically in the fall—to keep your system efficient and reduce the chance of breakdowns.

  • My furnace is 15+ years old. Should I repair or replace it?

    If your furnace is nearing the end of its lifespan, constantly breaking down, or driving up your utility bills, we may recommend replacement.

  • Why is my furnace blowing cold air?

    This could be caused by a dirty filter, malfunctioning thermostat, pilot light issue, or a more serious internal fault. A service call will help identify the exact problem.

  • Can I fix my furnace myself?

    For your safety, we don’t recommend DIY furnace repairs beyond checking filters or thermostat settings. Gas and electrical systems are best handled by trained professionals.
