New construction heating and cooling, Nashville
Felder Mechanical is a heating and cooling subcontractor for Middle Tennessee homebuilders and general contractors. We take each lot through rough-in, trim-out, start-up and the mechanical inspection, and keep the paperwork your office asks for in one packet.

The schedule
Each phase has a crew date, a list of what we need from you and an inspection where one applies.

The packet
Every builder account gets the same file. Our office keeps it current, so a superintendent is not chasing a certificate in closing week.

From the builders
“The rough-in crew sets the date with me the week before, and the passed inspection record reaches our office the same day. I stopped chasing paperwork.”
“Their bid sheet lists each phase and what they need from us. That ended the argument about who owed what at trim-out.”
“We send the plan set on Monday and get a scope sheet back with equipment and tonnage called out, so purchasing can compare line by line.”
“The license copy and the insurance certificate are in the packet every time, with our company named, before a draw goes out.”
Sample reviews.
Crews start from the shop on Elm Hill Pike. We bid lots in these counties; call about anything near the line.
We do not bid lots outside Middle Tennessee. For Knoxville, Chattanooga or Memphis, call a mechanical subcontractor in that market.
Before you bid
The plan set with the floor plans and, if you have them, the mechanical sheets. Add the lot count, your equipment spec and the window when framing finishes. We return a scope sheet and a bid that lists each phase.
For work under our permit, we request the mechanical inspections and tell your superintendent the date. If the permit is in your name, we tell you when the work is ready to call in.
Call the office by mid-afternoon the day before. We move the crew to the next ready lot on your list. The bid terms say how a return trip is handled when a crew arrives and the house is not ready.
What your spec calls for. We send the model, tonnage and efficiency rating for each plan for your approval before anything is ordered.
Yes. They are bid separately from a plan set, with the phases and the inspection plan laid out for the whole building.
We seal and prepare the duct system for the test. The test itself belongs to your energy rater, and we coordinate the date with them if you ask.
Tell us the building type and the lot count. A coordinator replies with the scope sheet and a rough-in date once the plan set is in.
