Get the right heating system for your building

Our HVAC company provides heater installation services for boilers and furnaces. If you’re trying to determine which type of heater is best for your space, we can help. Here are some of the major differences:

  • Installation cost:  Furnaces typically cost less money and time to install than boiler systems
  • Airflow:  Furnace systems can create drafts, spread dust and worsen allergies. Boilers require no ductwork and help keep your indoor air quality high
  • Energy-efficiency: Boilers are typically more energy-efficient than furnaces, and the heated water can be reused
