"Lake County Mechanical is the best!  They are always so quick to respond and fix the problem quickly.  We needed a new furnace in the middle of winter (Brrr) and they were able to install a new furnace in a day.  And it was a reasonable and cost efficient model.  We will trust LCM with all our heating and air issues.
