We have been using Rucker Mechanical for at least 15 years or so. They are always willing to fit us in if there is an emergency, and if we need to reschedule, they work with us on that, too. If there is any kind of problem, they come right back out to take care of that for us, too. Most recently, they did some electrical repair work for us, and they also did the routine seasonal work on the HVAC system. Overall, they are trustworthy, courteous and knowledgeable people! We have been very happy with them!
