Strine Heating and A/C is a family business, but they are large enough to be able to respond to any heating or A/C emergency we've ever had. Last fall, we had very hot weather the whole way into September & October. Our air conditioning unit (which we didn't purchase from Strine) had a part that gave out, and we had to call them on a Saturday afternoon. It was so hot, we couldn't wait until Monday, and they were there lickety-split! The serviceman knew just what to do, and had the part in his van that we needed. We were comfortable again within the hour.
