McWilliams Heating Cooling Plumbing

McWilliams Heating Cooling Plumbing has served Livingston and surrounding East Texas communities since the early 1970s, accumulating over five decades of field experience across residential and light commercial projects. The company holds current licenses and maintains an A+ rating with the Better Business Bureau, supported by 1,509 verified customer reviews that average 4.8 stars. Operating around the clock every day of the week, their dispatch team sends licensed technicians throughout Polk County and neighboring areas including Corrigan, Onalaska, and Groveton. This multigenerational family operation handles everything from routine seasonal maintenance to full system replacements and unexpected emergencies.

What distinguishes McWilliams from regional competitors is their ability to address three trade disciplines from a single invoice, eliminating the coordination headache of hiring separate HVAC, heating, and plumbing contractors. Their website advertises financing options through approved credit programs, making large-ticket items like dual system replacements or water heater upgrades more approachable for budget-conscious homeowners. The company stocks common replacement components, reducing wait times on standard repairs. Their service agreements include prioritized scheduling for enrolled clients and documented maintenance records that transfer to new property owners upon sale.
