  • In our 20+ year history working with WBG, they have proven themselves time and again to be a cut above the rest. As a national HVAC firm partnering with over 150 contractors, we hold our partners to a very high bar—and WBG consistently clears it. From construction projects to urgent service calls, their workmanship is among the best in the country. Their communication is seamless, their response times are elite, and they truly set the gold standard for mechanical contracting. We couldn’t recommend them more highly.

  • “Knowledgeable, dependable, reliable and transparent. WBG are wonderful partners to maintain and install our state-of-the-art equipment as well as our legacy systems. Having several systems ranging from chillers, mini-splits, pack units to boilers and heat pumps, WBG’s wonderful techs have kept us running through quarterly maintenance as well as late night emergencies. We could not function without WBG.”

  • “We have had a great relationship with the WBG team for more than 20 years, and they have consistently provided excellent service, professionalism, and support. They replaced 2 of our 3 AC units in a single day, stood behind their workmanship and warranty, and continue to provide reliable same day service when needed. Their quarterly maintenance program has also helped keep our systems running efficiently and gives us peace of mind knowing we have a trusted partner looking after our HVAC needs.”
