I had problems with my A/C this week and have a medical condition which means I need it working. Phoned Gam Air Conditioning, spoke to Jack. He and Gary arrived the next day, a very difficult fault to find and fix. If it was me I would have given up. They didn’t and now working perfectly. Thanks to both of you, very professional.

I have been using GAM for my air conditioning maintenance for over 20 years. Gary helped me replace an old system in my first home keeping as much if the existing system as sensible. He and his sons then helped me move this system to my next home and keeping what we could. GAM has always attempted to assist me with my plans and also giving advice to ensure I am on the right track. Their advice, work methods and skills have been excellent and the really care about the impact on my family and the outcome. Recommend them to anyone.
