I will never contact Wolff mechanical for business again and I recommend you finding someone else to fix your air conditioning. It took them a week to fix my air, A WEEK. No apologies from the actually company, just the repair who causally said "sorry this took so long". It was something simple as the external rotating fan. And once they finally got around to actually fixing it, they were missing another part, which they "never have ran out of before" which then took another two days for them to come out again. We called them every time asking for updates or to set up times, not once did they initiate the call. Please choose another company to fix your air. Unless you want to be displaced from your home for a week.
