Hi there,
I wish to share my experience to help the community to avoid these troubles.
I have a couple of split-type A/c units. I called around to find a company. I chose this company due to the first approach and clear website and their english.
1-I arranged the quotation and time slot on the phone.
2-On the designated day/time no one arrived. I called to discover they forgot the appointment.
3-after many hours they and many phone calls in between they finally arrived.
4-moving their tools they damages a door wood profile where a piece of profile came off.
5-finally they managed the cleaning of the air conditioning units. I paid them.
6-they left just to receive my call as the units where leaking water (to clean intact they have dismantled the whole plastic cover)
7-they came after few hours to fix the leaking.
8-fine? no. A unit after sometimes that is was running started to rattle no-stop. (Yes, of course was the bedroom's.)
9-I called back and after few days they arrived to "fix".
10-after 10 minutes they try to convince the unit was fine.
11-I lost patience. Calling and calling back with them their "Manager" they "solved" the problem putting a piece a paper behind the plastic cover and left.
12-the unit kept rattling all day....all night!
13-I tried to call back but this company never replied me back and avoiding answering my phone calls.
14-I had to call the manufacturer of my A/C to check and change a part broken during the cleaning.
15-From their 1st visit to the fixing this whole process took 1 month = all my weekends and no A/C in the meantime in the bedroom.
