Not cooling, not heating, strange noises or a code on the thermostat? Our technicians diagnose Trane systems on site and give you a firm price before any work begins. Have your model and serial number handy if you can see the label safely — it helps us check your warranty.

 ## New Trane systems: good, better, best

Trane offers single-stage, two-stage and variable-speed systems. Two-stage and variable-speed models run longer at lower speeds for steadier temperatures and better humidity control — a real advantage in Columbia summers. Your technician will match the right Trane system to your home's airflow, comfort goals and budget, and check that your ductwork can deliver the performance you're paying for.

 ## Repair or replace your Trane?

If your system is older or the repair is major, your technician will give you prices for both repair and replacement and a straight answer on which makes more sense. Replacing? We'll size the new system for your home — not just copy the old one — and give you one firm installed price. Financing is available for qualifying projects.

  ## A few common questions.

### Do you only work on Trane?

No. Trane is the brand we install most, and our NATE-certified technicians also service Carrier, Goodman, Daikin and other major brands.



### Is my Trane system still under warranty?

Send us your model and serial number and we'll help you check with Trane's warranty lookup. Trane warranties typically cover parts; labor and service charges depend on your terms, and we'll tell you what applies before any work begins.



### My Trane thermostat is showing a code. What does it mean?

A code points your technician in the right direction, but it doesn't always name the failed part. Write it down and share it when you call — then we'll diagnose it properly.



### How much does Trane repair cost?

Our residential diagnostic fee is $89, waived when you go ahead with the repair at the quoted price. You'll get a firm price before any work begins. Pay on site by cash, check or card, and your technician can walk you through financing options in person.
