Our Story
HVAC Repair Grounded in Fulshear and Fort Bend County
Robert Sullivan started Merrimack HVAC Group to serve the homes and families he knows best around Fulshear. Operating from the Gateway 359 Retail Center at 5430 FM 359 Rd Ste 300A, the team stays available every day of the week with 24/7 emergency HVAC repair so residents never wait when a system fails during the humid subtropical summers.
Work takes the crew through Cross Creek Ranch, Fulbrook, Weston Lakes, and into nearby spots in Katy, Richmond, and Simonton. The older housing stock mixed with newer builds near the Brazos River and Fulshear Town Square means systems face constant moisture and heat load, so repairs and AC replacement focus on real conditions on the ground rather than one-size-fits-all fixes.
