Services
Three services. One call.
HVAC, electrical, and plumbing for commercial tenants across DFW. Pick the service that broke, or tell us what happened and we’ll sort the rest.
Built around the corridor we work
Big Dog runs three commercial trades — HVAC, electrical, and plumbing — across the older Farmers Branch, Addison, and Lewisville building stock. Most of our work happens in 1950s and 1960s industrial and retail buildings: rooftop units that have outlived two ownership groups, panels sized for a different decade, and small-diameter drain lines that retail kitchens push past their original spec. Same crew on all three trades. One phone number. One invoice.

See detailsWhat each trade covers
HVAC
Commercial HVAC repair, maintenance, and replacement for tenants in older DFW buildings. Rooftop package units that short-cycle on the first 95° day, split systems that gave up over a long weekend, blower motors and compressors past their service life. Same-day dispatch.
Electrical
Commercial electrical for tenants who need an outlet added, a panel rebalanced, a circuit traced after the lunch-rush trip, or full tenant-improvement work before a Monday move-in. Every job runs under a licensed master electrician — to-code, signed off, and explained in plain language.
Plumbing
Commercial plumbing for the everyday calls — clogged floor drains in the warehouse, fixtures that quit in the lobby, water heaters that died on a Friday, small-diameter pipes patched twice already. We handle the work and the line-item invoice you can take to a CAM reconciliation.
Why one call beats three
Half the facility issues we get called on are not the trade the tenant thinks they are. A plumbing leak ends up an HVAC condensate line. A tripped breaker ends up a failing rooftop compressor. With three separate vendors, you finger-point. With one call, we dispatch the right tech — and bring the others if the job turns out to need them.
