Came in today because system was no keeping up with thermostat. When arrive notice that system was cycling. When testing system found that blower motor was heavily cover with hair and dust stoping air from circulating properly and overheating system. Also found sings of biological growth spreading through the system. Let costumer know about this issues and presented options. Costumer decided to move forward with enhancements. Proceed to clear blower motor, coil and added Germicidal light. System is not working properly. Thank you for choosing TE Certified. Would greatly appreciate a review, if you are happy with my services today.
