We recently purchased a new furnace system complete with a Micro Power Guard air cleaner as a result of a furnace tune-up offer showing that there were some potential issues with the old system. We are completely satisfied with the new system and with the great way that we were treated by your staff: Your service technician reviewed the original system and made recommendations and then handled the sales of the system and arranged the installation; your installers with the installation, trying out the new system and the cleaning up afterwards. We are extremely pleased with the results being shown with the Micro Power Guard air cleaner as my wife has some breathing issues. The dusting required now is greatly reduced compared to the past. This is the best air cleaner system we have had and we are looking forward to its continued working well. Thank you for your excellent service!
