Jim called me back very shortly after I had left a message. He was able to come out to my house the same day. He had been recommended by my son and I too would recommend him. My air conditioning was not working and Jim was able to fix it the same day because he explained that he carries these parts with him so his clients don’t have to wait. Especially in the recent humid days we are having
I called at 8 AM with a down AC unit and the service came out and it fixed in hour. Unbelievable response.....
They responded to my concern immediately, were there quickly the day before a holiday, diagnosed and fixed the problem within minutes, good price. Definitely recommend. Family owned business.
Great service, friendly, knowledgeable & trustworthy
Grenz has been providing service in our homes since 1999 and we are very satisfied customers! They’ve done maintenance, installed new furnaces and air conditioners. All work has been top notch for 20 years.
Knowledgeable, honesty, Integrity, and trustworthy are not words I just throw around. Grenz earns all of them in spades. They have earned my business for as long as I have breath in my lungs. Call them, you won’t regret it.
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.
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!
Grenz and Jim Jr give consistently outstanding service.
We are so happy to have found someone to fix our problems.
