The company serves both Phoenix (602.328.5000) and Tucson (520.292.6858), with extended daily hours from 6 AM to 10 PM weekdays and 7 AM to 10 PM on weekends — broader coverage than most competitors.

The plumbing division includes full residential plumbing services including toilet installation, shower drain repair, and general plumbing work. Additional services mentioned on the site include ductwork and system installation.

Chas Roberts is a notable presence in the Phoenix new construction market — the company is the installed HVAC contractor for Lennar home builds in the region, meaning many Phoenix homeowners with newer construction may already have a Chas Roberts system in their home. This makes them a logical first call for warranty and service work on those systems, though the warranty experience has generated some complaints (see below).

Named technicians who received specific positive mentions include Jesus (spring maintenance), Faran (thorough system check), Nick (damper diagnosis), Dylan (efficient service), Misael (technical explanation quality), Jesse (HVAC), and Ramon (plumbing). The technicians consistently receive praise for professionalism, communication, and thoroughness.

The one notable negative review involves a homeowner in a Lennar build who spent $3,000 over four years on a system installed by Chas Roberts, citing an unlevel furnace that had been collecting water above the master bedroom, and a motor replacement at four years old — with ongoing trip fees for warranty issues. That warranty experience reflects a specific risk for new construction homeowners using any contractor-installed system, but is worth noting for prospective customers.
