Grossman installed a new AC at my house and there was an issue with the existing duct work. Grossman repaired the duct work free of charge. Great customer service and very fast service.

The technician who came out couldn’t have been more accommodating. I was actually fine with the first thermostat he installed, but he wasn’t—he wanted to make sure everything was perfect. He literally left and came back with a better option that fit perfectly and is so easy to use. That level of care and attention is what really showed. I highly recommend Grossman’s A/C to anyone looking for a reliable and professional company.

We just wanted to say a big THANK YOU to Michelle and Gary. Our heating stopped working on a very cold night. Early next morning I left a message and within 10 minutes, Michelle returned the call and scheduled Gary to fix the problem at 9:00 am. What a great find for AC care! May God continue to bless the Grossman Air Conditioning Company. Tom and Andra Webb
