Rooftop Condenser Replacement
FLORISSANT, MO
Swapped a failed 30-ton packaged unit on a plastics plant roof with a high-efficiency model — downtime held to a single weekend.
When a rooftop unit dies on the hottest day of July, or a furnace cracks in January, you don't need a salesperson — you need a technician who knows your equipment by model number. We've kept St. Louis commercial and industrial systems running since 2009.

Word On The Street
“Our rooftop unit died on the hottest day of July and Lindbergh had a tech on the roof in under an hour. They got us back up before the afternoon shift even felt it. That's the kind of partner you want.”
“I run a cold storage warehouse and the chiller started losing temp on a Friday night. The technician who answered the emergency line actually knew the unit by model number. Saved thousands in product.”
“Signed up for the maintenance agreement two years ago and we haven't had a single surprise breakdown since. The quarterly reports actually show our energy bill going down. Worth every penny.”
“Redid the whole duct layout in our restaurant kitchen to pass a make-up air inspection. Clean work, clean invoice, passed inspection the first time. I've already recommended them to two other owners.”
System Down? Don't Wait.
Spoiled inventory, cancelled shifts, failed inspections, unhappy tenants — the cost of waiting dwarfs the cost of the call. Our emergency line is answered by a real technician who can start troubleshooting before the truck arrives.
