I have been using a Llyod 1 ton AC since the past 4 years. Faced several problems in the beginning due to an improper installation, which was done by the dealer. Finally, had to pay extra for a Lloyd technician, who did a good job. My bedroom is 14x14 and in a single storeyed independent house, the 1ton compressor runs more than usual, but does a good job of cooling up the room, in Hyderabad's summer. I'm looking to upgrade to a 1.5ton and Llyod is my first choice, again. But will ensure the installation is done by the company mechanic, instead of some unscrupulous dealer sent guy.
