Review of Grenz Service Company, LLC

This company is fantastic; they go above and beyond to do more than just sell an HVAC system but to make sure you get exactly what you need and are comfortable with the entire experience. Very friendly, professional and knowledgeable. We interviewed multiple companies before selecting Grenz and they were miles ahead of their competition on so many levels. Call them and give them a chance!

Quick response to service call




Review of Grenz Service Company, LLC

As normally occurs with Grenz Service Co, Jim was prompt with a response to a service call. Arrived to the site on time and found the vent blocking issue in a few minutes and corrected the problem


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.


Excellent Service!




Review of Grenz Service Company, LLC

We couldn't have asked for a better company to replace our furnaces. We reached out to three companies for a quote - all were good, but Grenz went above and beyond. First to respond to our request for a quote, first to provide the actual quote, and took the most time to work with us to find the right furnace solution. The installation was perfect, and now that the cold weather has hit - we can confirm we're 110% happy with our new system. Thank you to Jim and team for such great work!


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!


Saved our older fireplace!!




Review of Grenz Service Company, LLC

We have an older fireplace that other companies would not look at. Jim is very knowledgeable. He fixed various issues including a gas leak. Highly recommended.


Awesome service!!




Review of Grenz Service Company, LLC

Great service




Review of Grenz Service Company, LLC

Great work, love the explanation of what is being done and why. They are super thorough and give great advice about how to make the units last longer, work more efficiently, etc. They are kind, efficient, on time, hard working, and easy to work with!


Very quick and efficient




Review of Grenz Service Company, LLC

My motor went out on my fireplace. I called Grenz and they got back to me within 2 days and serviced and replaced the motor 1 day later. I would highly recommend them .


Great service, will definitely use Grenz again




Review of Grenz Service Company, LLC

With fall weather fast approaching, I was able to get inspections scheduled very quickly for my furnace and gas fireplace. Jim was so friendly and helpful. I like being able to have one company to call for furnace, AC and fireplace service.
