What happens after
you reach out.
Whether it's a repair or a full system, the process is the same one we've refined over three generations — measured, written down, fabricated in our own shop, and backed after we leave.
Comparing replacement quotes? Bring us the other company's — the second opinion is free.
Step 1
Free in-home estimate
We measure your home and run a real Manual J load calculation — the right size system, not a guess off square footage.
Step 2
A written quote with the rebate math done
Options across brands and tiers, in writing — with every utility rebate you qualify for identified before you sign, never after.
Step 3
Custom fabrication in our own shop
Transitions, plenums, and duct modifications get built in Glendale's in-house sheet metal shop, fitted to your home's actual mechanical space.
Step 4
Install day
Licensed, background-checked technicians install, commission, and test the system — and leave the workspace the way they found it.
Step 5
Walkthrough & registration
We walk you through the system and thermostat, then register your manufacturer warranty so the full published term applies.
Step 6
Backed after we leave
Our workmanship guarantee covers our craftsmanship for the life of your installed equipment — the same accountability three generations have traded on since 1938.
