Cobblestone Lane in Lincolnton
Last night the outside unit fan stopped working and will no longer kick on when you turn on the thermostat. The inside unit does kick on though, it's just the outside which keeps it from blowing cool air. My fiance only gets paid on Fridays and we have a young child in the house. Do you offer free service estimates and possibly billing options? We are hoping to avoid going all week with no air. Thank you for your time.

Smith Farm Road in Lincolnton
We just moved into an older home but a newer HVAC unit. We are looking into possibly wanting to set up a maintenance plan for someone to come maybe 2 times a year to inspect the system and make sure it is running properly. Additionally, currently we would like to have someone come take a look at the system and possibly adjust dampers if needed since we just moved in and want to make sure everything is set correctly. And lastly, we have installed a Honeywell wifi thermostat but are unsure if it is properly connected to the unit with the emergency heat. If these are items that someone might be able to handle and look at for us, could you please send me an email? My parents have been impressed with the work you have done for them so I thought possibly these are things you might be able to take care of for us. Thanks, Mindy
