Our Heating Replacement and Installation Process

A new heating installation takes careful planning and a thorough analysis of your current system. Our process goes far beyond removing your old furnace and plugging in a new one. We start by examining your current system and ductwork to identify issues that may be causing inefficiency. Even with a brand new unit, an inefficient or damaged system can put unnecessary stress on the unit and cause you to spend more on electricity. 


  1. Our technicians examine and assess your current system, including all ductwork, to identify damaged areas and design issues that may be causing inefficiency 
  2. If needed, we’ll modify and/or repair your ductwork to ensure your new unit is attached to a system that will maximize efficiency 
  3. We’ll calculate the appropriate unit size based on the size of your home and the features of your current system 
  4. Our technicians will prepare the area by covering your flooring and moving your belongings away from the space we’ll be working in
  5. We will then begin disassembling your old system and installing your new unit according to the manufacturer’s specifications
  6. Once installed, we’ll test and adjust the gas pressure of your new furnace – we’ll also test for combustion safety, carbon monoxide and gas leaks, and temperature control
  7. After testing and adjusting your new heating system, we’ll walk you through operation and maintenance steps, answer your questions, and explain your warranty
  8. Your old furnace unit will be removed and recycled, rather than brought to a landfill

We only install high-quality heating units from trusted, industry-leading brands like Heil. All of our products and services come with excellent warranties for your peace of mind and protection.
