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.
- Our technicians examine and assess your current system, including all ductwork, to identify damaged areas and design issues that may be causing inefficiency
- If needed, we’ll modify and/or repair your ductwork to ensure your new unit is attached to a system that will maximize efficiency
- We’ll calculate the appropriate unit size based on the size of your home and the features of your current system
- Our technicians will prepare the area by covering your flooring and moving your belongings away from the space we’ll be working in
- We will then begin disassembling your old system and installing your new unit according to the manufacturer’s specifications
- 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
- After testing and adjusting your new heating system, we’ll walk you through operation and maintenance steps, answer your questions, and explain your warranty
- 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 assurance and protection.
