In mid December my old split system Air Con unit died. I contacted several certified AC installers to quote on a new install, they knocked me back saying the job was too difficult due to two sets of narrow stairs & the location of the internal unit, directly above a bend in the stairs. I found 2 Masters through a friend of a friend. A technician came to my home, looked at the job & said " yes we can do this next week" Their office sent me a quote: Supplying the latest Mitsubishi 7 KW. And installing it. which included removing the old 50 Kilo external & 18 kilo internal units. Two installers arrived on time & did the job. They were very careful with not marking the internal walls, they had drop sheets to protect the floor. They removed all the old stuff & cleaned up before they left. I can't say enough positive things about 2 Masters. Last but certainly not least they beat every other price quote for the Mitsubishi AC unit.
