OUR REPUTATION IN THEIR WORDS trusted by Dane County families

“It’s been 20+ years since being in the market for an AC/Furnace and consider myself fortunate to have found Greiber Heating & Sheet Metal to work with.

Clearly knowledgeable and experienced, Devon Greiber provided thorough explanations of all product options with no pressure sales.

Greiber offered the best product pricing and most detailed accounting.

During installation, the staff were considerate and pleasant and provided a patient explanation on how to use the new thermostat.

All calls and emails have been promptly replied to as well.

I have every confidence in the professionals at Greiber Heating & Sheet Metal and the products they offer. Highly recommended.”
- Mariann M.

“Reese was incredible! He explained things thoroughly. He laid out my options and spoke about what to do when my HVAC stops working. Thank you so much Reese G. I truly appreciate you!”

- Taylor Z.

“Reese serviced my Carrier gas furnace that was not heating the condo properly, running constantly and never getting above 67'. He determined the issue was caused by condensation due to a plugged line and corrected it with a service call. I highly recommend contacting Greiber for their prompt service and professionalism.”

- Richard G.
