Performed tune up on 28 year old Carrier. Unit is not cooling the home. It is too small for this house and there is no attic insulation. Unit is also very loud, likely from having to work very hard to overcome issues. Unit is drawing more amps than it should, surprised it is still running. Client would like to upgrade his system and have attic insulation blown in.

Performed diagnostic on air conditioning system, operating upon arrival but not cooling. Checked refrigerant levels found system very very low. Dual run capacitor below manufacturer specifications, contactor burnt and pitted and compressor amperage high. 35 year old system with known leak. Recommend leak search and repair and parts or full replacement. Client declined needed repairs and recommendations except refrigerant. Added 4 pounds R22 and balanced no guarantee or warranty on refrigerant with known leak. Compressor running at 20 amps at 80 degrees outside with a max of 23 at 100. With amperage high it is at a higher rate for failure and compressor can lock out or trip breakers.

Performed tune up on air conditioner, replaced filter and cleaned outdoor unit. Heat exchanger burnt up and rusty very poor condition. Ductwork undersized for system, return duct and plenum full of rust and water, duct has multiple holes and debris. Blower motor leaking oil and over amping and blower capacitor below manufacturer specifications. Compressor over amping rated for 129 max on start up and is at 136, running max allowed amperage is 18 currently at 23, Compressor will fail. Dual run capacitor below manufacturer specifications and contactor is burnt and pitted. Metering device in evaporator coil not operating properly refrigerant levels constantly fluctuating which causes more stress on compressor, higher utility costs and poor performance. 20 year old Tempstar system operating upon completion but not well

Performed diagnostic on air conditioning system found low on R410A refrigerant. Advised client there is a leak in system, and a leak search would be needed to fix problem. Declined leak search at this time, added refrigerant but there is air in system so pressures are correct at 300 and 115. But getting 0 subcool and 28 superheat. To charge correctly without leak search full pumpdown and vacuum would be needed. System 14 years old recommend upgrading system due to age, efficiency and condition. System cooling upon completion but cannot guarantee system will operate properly through summer

Providing estimate to replace current system, 2003 Trane furnace and condenser, that is out of refrigerant. Current system is oversized for the home, which is likely the cause of premature failure. Put together a package for clients and look forward to working together to bring them comfort for many years to come. Thank you for choosing Certified.

Performing precision tune up service on 2004 Tempstar condenser, system runs. Checked refrigerant levels, removed second Contactor to reduce strain on transformer (should not be installed), fixed mounting bracket for dual capacitor, tested and inspected electrical and safety components. Added hard start kit to protect system from overamping, system was drawing 119 amps during start up and should not have exceeded 102 amps. System is now functioning much better, thanks for choosing Certified!
