Extremely Responsive. Honest Work.




Review of Grenz Service Company, LLC

Contacted Grenz on a Sunday. Jim was back in touch within an hour. The problem was fixed the next day, after other contractors either didn’t know how to or didn’t want to repair. Or worse, they pushed to replace the furnace. This long time issue is now fixed and no longer a worry.

Attentive Service!




Review of Grenz Service Company, LLC

Grenz has been our heating/cooling service provider of choice over the years. We own a 1800’s Victorian home where we find most home service providers flee. Jim and team are super friendly, consistent with great service and pricing is competitive. Thanks for updating both our heating and cooling systems, the new energy efficient systems are awesome!
