During the 15 years we've owned this place, we've had the "pleasure" of replacing both the heating and the air conditioning units of our home. Both times we're relied on Crain Heating & Air here in Jeffersonville.
http://www.craincomfort.comThey were prompt, efficient and reliable in all our dealings. We did have one issue with the level of the central HVAC unit which resulted in some water damage to the ceiling downstairs when the A/C side froze up. But, they came out, repaired the unit, repaired the damage and it was as good as new.
All in all, we would call on them again for future problems and they come out annually for the inspection/checkup. Also, they have 24-hour emergency service available.
