Zero Stars if possible. Summer of 2017 one of our HVAC units was freezing over and not functioning. Hanna's Mechanical (then contractor of American Home Shield AHS ordered a new valve based upon their leak diagnosis. When the valve came in (a LONG and HOT time later), the repair work was finally completed on November 9th. A new valve was installed and I was told that the system was pressure tested. I was advised, based upon the pressure test, that the system was holding the pressure and that the system could be re-filled with freon (any remaining freon had to be emptied in order to run the test). Based on their statement that the system was holding pressure, I paid them $725 to re-fill the unit with Freon. I later learned that they really should have preformed a dye test. Since it was November in NJ, the system was changed over to winter/heat for the season. I requested a written receipt from Hanna's Mechanical for work that was conducted and a receipt has never provided. In April 2018 the system was switched back to Air Conditioning for summer. The system did not function. I called Hanna's Mechanical and spoke with Barbara on April 16th @ 3:36 pm. I advised her that the unit was not working. She would not help me or send someone for service and told me to follow up with American Home Shield as they no longer worked with AHS. (Hanna's Mechanical refused to stand behind their work.) I phoned American Home Shield. I was again notified that Hanna's Mechanical no longer worked with American Home Shield. Another AHS HVAC contractor was sent out for service on 4/18/18. They diagnosed that the upstairs AC unit was extremely low on Freon and that they needed to conduct a leak test to determine the source. Preforming the leak test would release any remaining Freon in the system. The system was not used since the November repair until April 2018 when it was diagnosed as almost empty of Freon, so Hanna's Mechanical either did not perform the fix properly or they did not fill the unit with Freon. read more

Mike and Mark will definitely be back to do more future work. Not only did they show up on time, they were clean, and really provided great customer service. Honest workers too. Thanks, guy. 5 Star girl.... read more

They did a great job. Mike the owner went above and beyond. They quoted me about half of what every other company had quoted me for a coil change. His guys came and completed the job in a very short period of time. They were very informative. They also do plumbing and electrical. I will definitely use them again and I recommend them to all of my friends and family read more

Hanna's Mechanical Contractors - Heating & Air Conditioning/HVAC Near Me - Milltown, New Jersey

Talk about quick service! My central heat decided not to work on the coldest day of the year. I called Hanna's, Barbra answered and was very helpful. She forwarded me to a tech who then came to my house and solved the problem. Professional young crew who were very respectful. The price wasn't outrageous and they do CLEAN work. Very professional. I recommend this place for anyone or business. read more

We recently moved into a rented townhome in Franklin Park, NJ and these contractors were given to us through American Home Warranty. We had an emergency repair that needed to be done as a toilet was leaking through the floor from our upstairs into the dining room and we had a sag in the ceiling literally filled with water! They were able to squeeze in my request and had someone over within a few hours. Not only was the person who serviced us, by the name of Carlton, friendly, prompt, and thorough, he also told us what to do with the sag in the ceiling as well as checking out the toilet in the other room. I wish every service request was like this! Thank you so much Carlton and Hanna's :) read more

I like family owned businesses especially when they take pride in their work. So I have no shame in saying that I know nothing when it comes to any large appliance in my basement. I guess I was putting off turning on my heat because I was in denial that winter was upon us. Anyway I go to turn it on and it's not working...problem. I call the big name company and tell them they need to come take a look. Their technician told me I had to replace this and that and if I didn't it would be dangerous and so on and oh this will cost 8,000... Wow so I decided to get a second opinion. I heard about Hanna's through mutual friends that said they did a great job. I called and they were able to come that day. I explained what had happened and they said they would take a look. So very long story made a bit shorter Hanna's technician explained it was an easier problem to fix and they quoted me pretty much half what the other guys said. Well this all happened in late September and I'm happy to report my heater is still working perfectly. I definitely recommend them. It's hard to come by honest workers these days. read more

Hanna's Mechanical Contractors, specifically Mike and Mark, came to our house to inspect a leak we had noticed coming from our water heater, and kindly looked into a couple of other plumbing issues we had. As a courtesy, they tightened the valve leading to an outdoor faucet which had recently been leaking (preventing any further leaking), and they also replaced a washer for a different outdoor faucet which was attached to our watering hose. I was impressed with their knowledge, efficiency, and inclination to help. It is good to know that someone is trying their best to help! read more

Beware! Our A/C has now been broken for over 4 weeks because this company keeps coming back and simply refilling the AC with free-on instead of actually fixing it. The receptionist Barbara is extremely rude and doesn't communicate well over the phone. The repairman is always late (they've been here 4 times already and always show up 2 hours late), he also smells of smoke and drags dirt all over my living room floor. It's extremely frustrating to deal with this company when it's 85 degrees and all I want is for them to fix my AC. They ordered a part supposedly 3 weeks ago, it's still not in so we are suffering in the heat. Their "emergency" phone number goes to a cell phone for the manager who never calls back. Every time I've left a message to check on this part, I never get a call back and as a result I have to deal with the receptionist, Barbara, who instead of answering questions, always says "I don't take threats well". Ugh... How frustrating!!! read more
