Jim came out to tune up our 2 gas fireplaces yesterday. The service exceeded my expectations—found a small gas leak (yikes) & addressed it, replaced the starter (part was free) and Jim graciously shared is knowledge to help me maintain the fireplaces for the future. I definitely recommend Grenz Service.
My AC unit stopped working on a Friday morning. Jim was able to come out within a couple of hours that afternoon. He was very knowledgeable and knew right away what the problem was. I appreciated that he explained to me what was wrong. I have Grenz scheduled for general maintenance coming up and know I’ve got a great company coming.
Awesome customer service. Fully explained what he was doing. Reasonable pricing. Would definitely recommend.
Explained situation well
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 .
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.
I own four retail stores, and Grenz has been doing our repairs for at least the last five years! Very prompt and dependable to get your equipment running! Highly recommend!
Returned phone call, they were able to diagnose problem and fix the same day. Was a tough job that they found a way to handle. My new cooler company!!
Good Company......friendly,professional people.....knowledgeable in their products.
Very fair price, install was very professional. I purchased a new HVAC system, largely based on their reputation
Jim Jr is a very personable and highly qualified technician. We will call him from now on!
Great service, very knowledgeable and reliable. Jim not only solved the problem with my ice maker but he also walked through preventative maintenance recommendations.
