Does it know HVAC equipment brands and specs?

Can I use it for both residential and light commercial jobs?
Yes. Whether it's a residential split system swap, a new construction install, a mini split, or a light commercial rooftop unit, WonTheJob handles it. Just describe the scope and it writes the appropriate proposal with the right terminology for each job type.
