He freely acknowledged he did not open up to do an actual visual inspection on the unit. He said it was because the flames were Orange. Another contractor came and told me the Orange was caused by dirty burners in crossover tubes. He told me my furnace was a safety hazard and had to turn it off and I must buy a new heating system.. You wouldn't offer me a replacement part option even though the parts are under the factory warranty I do. He told me that he'd exchange her how to factory recall and I asked for a manufacturer's bulletin. The bulletin he provided stated The furnace needs an additional grounding wire for a lot of models in my model was not one of them.. Dishonest, Deceptive, And clearly is not trained in basic service and maintenance on heating equipment. He clearly only cared about selling me new equipment equipment and not resolving my basic me this thing my basic maintenance problem.

We decided on a new Carrier high efficiency as repairs would be too costly. Their crew came on Tuesday and removed and installed a new furnace in 2 1/2 hours.

When my furnace was not running right I called only to be told that now they joined a larger company they do not do mobile home furnaces, really a furnace is a furnace right. So I needed to find another HVAC company. I called Trinity Heating and cooling solutions. Zack was not concerned if my furnace was a mobile home furnace at all. He came, fixed what was going on and we decided to get a new furnace. Him and his crew was here today on time like he promised. I had to leave for an emergency and when I got home everything was done and cleaned up. Very polite, knows what he is talking about and is dependable. Thank you Zack and crew for the great job.

Korthase and Sons gave us all of our options and took the time to bring the whole unit back to their shop and rebuild the engine, saving us thousands over a new unit!

My 95 year old mom lives on a fixed income, in her own home, which was built in 1936…read more Her kids (including me) have been worried that she needed her electrical updated bc we had no idea if it ever had been. We got 3 estimates from licensed, insured electrical companies in the Muskegon area. The estimates were all fairly similar. BUT Korthase was the only one that was honest in telling us that her current electrical actually looked pretty good (it must have been updated from when the house was built, but we had no way of knowing that) and given that she would not likely be in her home for all that much longer, they said in their assessment, a big upgrade was not necessary. This saved my mom 5k! Apparently, there ARE honest companies and Korthase appears to be one of them.

To my disappointment, I experienced no return calls, not showing up for scheduled appointments, fully paid for unfinished jobs, overcharging and mediocre quality of work. Then, I contacted Marcos (Real Remodeling). When I called, he answered. If I had to leave a message, my calls were returned right away. Appointments were kept as scheduled. Pricing was more than reasonable and the work quality was outstanding. Marcos is intelligent, friendly and actually knows what good customer service means.
