"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."

"Quenton is very knowledgeable about HVAC Very honest, He added the right size furnace and air conditioner for the size of our house. Others wanted to oversize and up sell to items we really didn't need."

"Since we have lived in this current home, Crome Mechanical Heating & Cooling has installed a new Lennox high efficiency ductless ac/heating system and a Lennox high efficiency boiler. Both units have performed very well in a cost effective manner. Meanwhile, I am certain Crome Mechanical will maintain our equipment at a high level of service."

"I was able to reach the owner during his vacation, which surprised me. He was very prompt at visiting the hoiuse and sending a quote for the A/C and Furnace replacement. The work was completed on the date selected and in very little time. I'm impressed. I would eagerly recommend this contractor to anyone."

"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."

"Very professional. Replaced furnace & Air conditioner plus new water heater a Humidifier plus Hi Tech thermostat. I had made 4 requests to heating and cooling companies. They came in with a lower bid and superior product. Work was scheduled and they completed everything within 1 day. Everything was completed with exception of charging the air conditioner which must wait until Spring weather. A very professional company to work with!"

"PROESSIONAL AND COURTEOUS SERVICE WITH HOMETOWN VALUES"

"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."
