Mull Bros Inc.

Mull Bros Inc operates as an air conditioning and heating contractor in Wethersfield, Connecticut, earning a 4.7-star average from 26 verified customer reviews. The family-run business maintains standard weekday hours from 8 AM to 4 PM, providing service calls throughout the Wethersfield area and neighboring Connecticut communities. Customers consistently describe the team as professional, efficient, and reliable, with particular praise directed toward a lead technician named Tom who handles consultations and installations.

What distinguishes Mull Bros Inc from neighboring contractors is their involvement with the Energize CT rebate program, enabling homeowners to access state and federal tax incentives when upgrading to heat pump systems. Reviewer Michael Wilkosz documented his experience qualifying for these rebates while having a heat pump installed to replace aging central air, noting that the team provided upfront assessments of what the project would require. The company also offers competitive pricing, with customer Brittney Davis noting they beat every competing quote for a new AC installation including duct work.

Two recent projects illustrate the company's approach to tricky installations. Sam Thomas called on Mull Bros when his heating boiler failed, and the team completed a replacement quickly without lengthy downtime. In a more complex case, Michael Wilkosz discovered that previous contractors had cut numerous corners in his home, including wiring both indoor and outdoor units to a single electrical breaker, and the team resolved these code violations during his heat pump installation.
