servicearea_w_hendrickscty_mapControl Tech’s service department is one of the finest in central Indiana. All of our Service Vehicles are radio dispatched; this provides us with timely service. When our customers call us we have a live person answer the phone not a machine with a recording. Our customers are provided with a time that our service technician will be at their home or place of business. If for some reason that we are behind schedule our service dispatcher will notify the homeowner, we feel that this is very important in today’s busy schedules. We do follow up calls after service is done to insure that you are satisfied with our services. We back our repair parts with a one-year part and labor warranty on most repairs; this gives our customer a peace of mind. Control Tech provides 24-hour emergency service 365 days a year.


All our estimates for new equipment are free of charge. Our estimates give detailed information about the job, there is no hidden cost and all options for Auxiliary products and upgrades are provided on estimate with cost, this allows our customers to make their own decision if they want to add any additional options or upgrades. Our customer makes their own decision and there is no pressure to make the customer uncomfortable. Control Tech is locally and independently owned and operated, we employ certified installers (no subcontractors) to insure that the work we do meets or exceeds manufacturers specs. When you choose Control Tech for your heating, cooling, and geothermal needs you can rest assured that we will stand behind our products and workmanship. Contact us today for a free estimate.
