All installations are done to New York State code, and we provide full testing before leaving your home.

FAQs About Furnace Repair & Installation

  • How long does a furnace last?

    With regular maintenance, most furnaces last 12–20 years. After 15 years, efficiency and reliability often begin to drop.

  • Should I repair or replace my furnace?

    If repairs are frequent or the unit is more than 15 years old, replacement may be more cost-effective. We’ll help you weigh your options.

  • Do you offer maintenance services?

    Yes. Seasonal tune-ups help extend furnace life, improve performance, and catch problems early.

  • What size furnace do I need?

    We calculate furnace size based on your home’s square footage, insulation, and layout. Oversized or undersized units reduce efficiency and comfort.
