Frequently Asked Questions

  • How often should I replace my furnace filter?

    Replace your furnace filter every 1-3 months depending on usage and filter type. Standard fiberglass filters need monthly replacement, while high-efficiency pleated filters last up to three months.

  • What are signs my furnace needs repair?

    Watch for unusual noises, inconsistent temperatures, frequent cycling, yellow pilot light flames, or rising energy bills. These indicate potential issues with ignition, thermostats, or heat exchangers requiring professional diagnosis.

  • When should I schedule AC maintenance?

    Schedule air conditioning maintenance in early spring before cooling season begins. Annual tune-ups include refrigerant checks, coil cleaning, and electrical inspections that prevent mid-summer breakdowns and improve efficiency.

  • How long do HVAC systems typically last?

    Furnaces last 15-20 years with proper maintenance, while air conditioners typically last 10-15 years. Regular tune-ups, filter changes, and prompt repairs extend equipment life significantly beyond average expectations.

  • What causes uneven temperatures between rooms?

    Uneven temperatures result from ductwork leaks, blocked vents, improper system sizing, or poor insulation. Custom ductwork modifications and airflow balancing can eliminate hot and cold spots effectively.

  • Are mini-splits good for Michigan winters?

    Modern mini-split heat pumps work efficiently in Michigan winters, maintaining heating capacity even at sub-zero temperatures. They're ideal for room additions, converted spaces, and homes without existing ductwork.

  • How do I know if my water heater is failing?

    Signs include inconsistent hot water, strange noises, visible corrosion, or leaks around the tank base. Rumbling sounds indicate sediment buildup, while lukewarm water suggests failed heating elements.

  • What's the difference between furnace repair and replacement?

    Consider replacement when repair costs exceed 50% of a new unit's price, your furnace is over 15 years old, or efficiency ratings fall below 80% AFUE.

  • Why does my AC freeze up?

    AC units freeze due to restricted airflow from dirty filters, blocked vents, or low refrigerant levels. Turn off the system, check filters, and ensure vents are open before calling for professional service.

  • Can custom ductwork improve energy efficiency?

    Yes, custom ductwork eliminates air leaks that waste up to 30% of conditioned air. Properly sized and sealed ducts maintain correct air velocity and pressure balance throughout your home.
