Updating a Heating System for Modern Functionality

Recently, we got a call from a homeowner who wanted a new thermostat installed in their home. They called us hoping we would be a knowledgeable McHenry heating company. Their first question they had was whether or not their furnace was compatible with a new thermostat. We let them know that our technicians would be able to let them know the answer to that question when he comes out to their home. The homeowner was ready for us to come out as soon as possible, and we were able to send out a technician that same day.

The heating company experts were on their way!

One of our professional HVAC contractors arrived at the McHenry residence about thirty minutes after the homeowner had contacted us. The homeowner showed our technician the furnace and the thermostat. We checked out the system and determined that a new digital model would absolutely work for them.

Our technician started removing the old thermostat. Once he had it removed he started installing the new digital thermostat. Our technician connected the wired precisely until he had the thermostat was installed. Our tech started showing the homeowner the different features that the digital thermostat has and how the homeowner could set it. They were really happy with all of the new features, as they had a dial thermostat before we completed our work.

Our tech showed the homeowner the manual for the thermostat and he let him know that most questions that he may have will probably be covered in the manual, but if it wasn’t, then he could contact the office and our of our techs would be able to answer any questions for him. The homeowner couldn’t get over all the different features that were provided and him and his family were having fun just getting familiarized with the new digital thermostat.
