    Well our HVAC saga continues but hopefully on a better path…read more This process as my reviews describe has been a challenge but I will give kudos when due. Arlinghaus has decided to change out the outdoor unit increasing size thus matching what was replaced. This is considerable expense to them but was the honorable thing to do. Hopefully this will be the final. Update to this review. In the end, Arlinghaus made a mistake sizing our replacement equipment up front but has gone a long way correcting that mistake in the end which is what really matters!

    It's been almost 2 years since they installed our new HVAC and it still doesn't work and we can't…read moreget a call back. The technicians are lovely, friendly and polite. But the thermostats installed have never worked right. We've complained about them and had them out to check them and program them multiple times. Only one guy understands them so most of the techs made it worse. He got them to sorta work, but he revealed that they reset to defaults if the power goes out. They finally agreed to switch them out a week ago. Tech couldn't do it. Now there's a problem with the wiring. We've had no AC or fan for a week. We've called every single day and can only get their call service. They had to cut a hole in our ceiling to run duct work. They had a contractor repair it. The repair fell apart in months. Nobody EVER returned our calls. We finally had to pay our handyman to fix it. If they ever finish the job I'll let you know how their work is.

    I started with these guys when they were small. Needed them for a problem with my daughter's…read morefurnace this past winter. I was unable to get a return call. Also am out $180.00 for purchasing a yearly membership when they had last serviced my furnace in fall. Not to mention I purchased a furnace from them 3 years ago. I used to think the owner, Josh, was pretty decent as were his crews. I wouldn't give you 3 cents for them now .

    If there was no star , that would be the most accurate. JM Mechanical in Cincinnati is the…read moreoriginal installer of our AC HVAC unit. I called them because the AC was not cooling enough, ( Chris ) from JM came and said that there is a leak, need to find the leak, fix it and fill it with Refrigerant. He gave an estimate of $1070. I gave the okay to fix it. After they did the work, it still not working properly. They came the next day and got the unit to work and bring the temperature to 72 degree. That was in April, 2026. On June 12, 2026, I called JM Mechanical again for the same problem, the AC is on all time and temperature will not drop below 78-79 degrees. Nick Bell from JM came and said that the Coils are clogged and need to be clean. Not sure why they didn't diagnose this issue the first time. The worse part was Nick Bell told me that they couldn't clean the clogged coils because they are very busy and the earliest they could come is over a month from today. Nick gave me the company owners name ( Kyle) and asked to call him. I call Kyle and his phone number is no longer in service. Then I called the direct company phone number and no one picked up. Left messages and I am still waiting for a call back. It is now 5 days! And still waiting! What kind of company is this. I DON'T recommend this company JM Mechanical and will never use them again.

    We woke up to our house being 59degrees and the furnace not working. Tyler W. Was able to make it…read moreout before lunch time and was a great help! Customer service was absolutely fantastic and Tyler W. was accommodating and gave us clear explanations as to what was wrong. We received a text message with a picture of the employees so we knew who to expect and what they looked like. Arlinghaus has to send another worker out to discuss prices on a new furnace. Tyler was able to get our furnace working temporarily as we look into buying a new furnace. It cost $89 for him to come out and diagnose the problem. They will remove this from any extra work they may need to do. Unfortunately, in the end we could not afford even the lowest option they had for a furnace. They use a top furnace line brand and are more expensive then the national average. This was the only draw back for me that it was to expensive and I did not want to enter into a loan for a $7,000 furnace when the average homeowners pay is $3100. Regardless, they were transparent and did not pressure me into anything we didn't want to do. I highly recommend Arlinghaus for their professionalism and honesty with their customers.

    Total rip off. Please don't use them! They hire young people who have no idea what they are doing…read moreor talking about, they are just sales people dressed in uniform. Their price is outrageous and no they still charge you if you don't use them for repair. Basically they bait and switch
