I had not used Westenn before and wondered if any emergency service repair companies would be answering during the holidays. My call was promptly answered and a service person was on his way.

When I was shopping for a new heating and AC unit, I received three bids. I chose Two Seasons in Walworth and Mike explained the various units available with expert detail.

Checked my spam, snail mail and junk mail, nothing. I finally picked out another contractor and just had it installed yesterday. I told my new contractor about not getting a quote from 1 company without naming this company. He said to me Would that be JC Hvac? I said yes. He said you wouldn't believe how many other customers tell me they never got their quotes either after Jason showed up. So obviously JC Hvac has enough business without quoting new jobs. I got a better idea. How about not wasting my time and others when you have no intention of doing the job or providing a quote?
