About Mattson Mechanical
Mattson Mechanical operates as a residential HVAC contractor in Galveston, Texas, delivering heating and cooling services to homeowners across the island community. Based on the 14 customer reviews collected, the company maintains a strong 4.7-star average rating, reflecting consistent service quality that residents along the Gulf coast depend on year-round. The team led by DeWayne Mattson serves the Galveston area, responding to both routine maintenance requests and urgent climate control emergencies that island living inevitably brings.
What distinguishes Mattson Mechanical from other island contractors is their ability to maintain operations through extreme weather events, a critical qualification for any service provider along the Texas Gulf Coast. Multiple reviewers specifically praise the owner and crew for answering the phone immediately, arriving promptly, and completing work without unnecessary delays. While much of the website remains under development, the company appears to focus on core residential replacement and repair services rather than extensive specialty divisions.
Customer testimonials reveal specific scenarios that illustrate the company's approach. Dan Van Zandt describes how Mattson Mechanical installed a new cooling unit within a week of Hurricane Beryl passing through Galveston, restoring comfort to his home on the Seawall despite ongoing power surges affecting the island. Greg Ball emphasizes that DeWayne and his crew members answer the phone when called, a practical advantage in a market where many contractors become unreachable, and complete jobs efficiently.
What Customers Say
Three of 8 reviewers specifically mention same-day or immediate response capabilities as a key factor in their positive experience. Five-star reviews uniformly describe DeWayne or crew members by name, while the single negative review centers on follow-up service disputes rather than initial installation quality. Four reviewers reference the company's reliability during or after severe weather events.
