"Jordan was very quick and did a great job installing a new furnace. Completely replaced the entire unit along with the air conditioning unit. Very friendly and respectful and answered all questions asked before, during and after job was completed. Very knowledgeable and explained everything in detail."

"They were here the next day, and installed the furnace in two days, just enough time to wait for parts. They were fast, clean, and their work was great."

"Crome Mechanical is the best! We have hot-water baseboard heat, which we love, but that means no duct-work for a/c. Our research showed a 'split' would meet our needs, and Lennox was the recommended brand. I contacted Crome and was visited within several days by the owner. He was extremely knowledgable and very friendly. His technicians did a perfect installation. We were so impressed by Crome and the equipment, we had a 2nd split installed the next year. I cannot recommend Crome enough!"

"I went with the other contractor due to the fact they included a 7 year maintenance warranty, the company has been around for over 100 years."

"They've maintenanced my furnace before I required a new one and they've always maintenanced the new one since I got it replaced about 3 years ago. Very easy to work with. I think I've been using them since 2008."

"Computer did the "gotta send info to Microsoft" but when tried to reboot it ran through automatic repair without success. I did all the alternative without any success. He came and picked up the hard drive on Tuesday and returned it on Saturday. Fortunately he was able to "restore" without any data loss. Very happy with outcome."

"Went OK. They did the work and it 'mostly worked' when they were done. I say mostly because the pressure valve was blowing off of the boiler when they were done (This was NOT happening before they had done the work). I had noticed this the day after I had paid. I contacted them and they wanted to replace the expansion tank and charge me $200. I asked - shouldn't this be covered under the initial work of $4600? They said the part wasn't explicitly in the quote. Frankly at this point to replace what really was a $40 part and half hour of time to do a fully finished job (for $4600). For 1. How am I supposed to know (as a customer) what should be on the quote for a fully finished job (pumps, piping, etc? - they are the expert) 2. How am I supposed to know this isnt their fault. (Shouldnt an autofilling expansion tank be connected to the incoming water supply?) Frankly not standing fully behind their work and making sure they do everything to do a good, finished job - left a 'bad' taste in my mouth. In the end I replaced the auto-filling expansion tank with an Extrol expansion tank for $40 and it took me less than an hour. After that it all appears to work."

"Excellent. They explained the process to us before starting, took before and after photos of the ducts. They worked hard and cleaned up thoroughly when they finished."

"He removed the old unit, and put in the new unit. A little difficulty getting the old unit out of the wall mount, but he got it out, and aided with the disposal of the old unit."
