Our regular HVAC guys no longer check their messages on the weekends. My sister found Atzl on yelp. We called and spoke to Tom. Within half an hour, he was in my home, checking the thermostat and the heating unit. He found the issue immediately. He then very thoroughly checked out all the connections to make sure there was nothing else wrong. Then he explained the situation to me so I know what to do if it happens again in the future. He couldn't have been nicer. To put icing on the cake, his fee was very reasonable. I cannot recommend him enough.

Second, loved the time they took and the way they cleaned up. It was quick and the result was awesome and professional. Third, although had a tiny leaking issue, they came right back next day in the morning and fixed it quickly. Last, I was worried that I would get some feedback regarding to like "it will be hard to do etc, so the estimate price will need to be adjusted. But turned out I worried too much! They went with the estimate they provided in the beginning, worked on the job without a single complain, and provided fast response and help after service. There was nothing I could complain!!

I met with Grossman to swap out a toilet & the water controls in a shower (non-emergency service call). Matt came to my house to provide an estimate. We scheduled a time for him to return a few days later (11/2020). They came and they did a good job. There were no economic surprises. They cleaned up their mess and everything works fine. I've attached a picture of his neat workmanship of the shower cartridge (hidden behind the wall). IMO, he did a good job & I will be using Grossman again.

The installation of said unit caused the condenser unit to overflow and shut off, so no AC because of their maintenance, and no value of maintenance contract because they cant honor their 24 hour service guarantee.
