We decided to replace our 14 year old condo split system before the heat really gets chugging here in Scottsdale. Tomer took a look at the unit top (4 story roof) to bottom, tested every function and said we could get another season or 2 out of it if we needed to. The estimate was clear and concise. From our agreement to installation was only 3 days. His crew was timely, courteous, efficient and FAST.
