Airstar serviced our air conditioner when we first moved in or home. They did a great job at a good price. I used a coupon that was in a local ad that made the price better. The only reason I use a different company now is because the other company is smaller and can get here sooner than Airstar. But Airstars time range isn't unreasonable at all especially during peak season they got here faster than most other company. I would recommend them to anyone.
