1. Visually inspected condenser coil for debris/ dirty. 2. Inspected condenser fan motor. 3. Inspected condenser fan blades. 4. Inspected/ cleaned wiring connections. 5. Tested compressor/ condenser fan motor capacitor. 6. Checked compressor amp draw. 7. Checked condenser fan motor amp draw. 8. Inspected / replaced return filter. 9. Inspected return plenum for debris/ dirty. 10. Inspected evaporator coil. 11. Inspected blower motor/ blower wheel. 12. Checked blower amp draw. 13. Measured temperature differential from supply to return. 20 degrees measured. 14. Inspected drain lines and treated to prevent blockages 15. Washed condenser unit to promote heat exchange Was not able to offer duct cleaning as the vent was on the roof with a very steep pitch. Advised by office not to cut it open to see if it was blocked. Found big air leak from large deformation of the bottom of the unit that was hastily taped up. Found high start amps on compressor. Sealed coil to prevent air from leaking
Performed single system cooling maintenance on 2018 heat pump. I checked amps, capacitor, filter, drains, cleanliness, refrigerant temperature, and temperature differential. The system is performing within manufacture specifications. The son spoke to me about the room still being warm. I advise that a return be installed in that to help cycle the heat out. If issue persists after return installation, it is advised to add more insulation in the attic space. The evaporator coil has minor oxidation and could use light cleaning to allow better temperature transfer. This would restore some of the system’s lost efficiency.
We arrived at our clients home for the main unit not cooling properly. The homeowner showed us the thermostat and said that the unit would run continuously without dropping the temperature in the home. We spoke with Will over the phone and he informed us that the indoor air handler had been replaced last year with some additional duct work done in the entire home. We first proceeded into the attic and verified the unit was on and calling to cool. We then went outside and tested all the electrical components on the 2009 heat pump. It has had multiple parts replaced already. Everything is currently testing within manufacture specification's with the exception of the defrost control board. It has a significant burn mark from overheating on it. When we read the refrigerant pressure we immediately found the unit to be nearly empty of Freon. We proceeded back inside and preformed a courtesy leak search in the air handler. We found the leak in the middle of the evaporator coil. I attempted t
I performed visual inspection of HVAC system and found the thermostat shutting off due to a shorted contactor for the heat strips. Contactor was replaced and the customer was reimbursed for the difference in cost. No further issues at this time.

I thoroughly examined the cleanliness of 2 gas systems. Systems are from 2012 and the manufacturer is carrier. 1. Both systems have excessive dust build up within the ducts and plenums. 2. The blowers have minimal build up and should be fine for another year or two. 3. Both systems have poor filtration and this allows dust to bypass the filter. 4. The downstairs system has a compromised emergency drain pan. This makes it a major risk for causing water damage. 5. I observed that neither system has water safety switches and having them is highly recommended. 6. The upstairs system is short 600CFM on return air. This causes unnecessary wear and tear on your blower motor, heat exchanger, evaporator coil, and compressor. This wear leads to premature failure in major components.
Checked refrigerant pressure and attempted to force the outdoor into defrost and it would not cycle. Defrost board is faulty and needs replaced.
Performed operational inspection of air handler and systematic check. We found out that there was a short to the thermostat when the system operated under electric heat strips. The holding coil on the contactor would slightly short to ground without popping the fuse but would cycle the thermostat off and on when in defrost mode.
Perform system maintenance on unit cleaned electronic air filters outdoor condensing coil had laid debris across it rinse coil off for better airflow condensing coils. Notice partial growth across the motor and debris in evaporator coil debris in the evaporator coil causes the lack of airflow, reducing efficiency and causing your compressor to wear a little faster than normal recommending installing APC_X UV light to eliminate continuous growth on fan motor evaporator coil also eliminating dust particles and contaminants inside your home. Also recommending cleaning the evaporator coil while in place to free up more area on the coil for better airflow, efficiency, and to extend the life of your unit.
Ductwork repair. Tied into existing Return Plenum, cut in a new Return Duct using R6 Flex 14” Duct, boot, and Grill. Add VIP Annual Preventive Maintenance (includes 2 preventive Seasonal Maintenance and 10% off future parts/repairs, and priority service with discounted service dispatch charges) Washed Coil inside out on outdoor Heat Pump Everything is functioning properly at this time
Emergency Ac Repair. Found out the system was low on Freon and not cooling properly. Performed a leak search and found one leak at the shredder of the suction line at the evap coil leaking. I tightened it with the customer and re checked it with him present and there in no leak present at this time. I charged the system with 4 pounds of Freon and the unit is cooling well at this time. Noticed the capacitor is gust out of the recommended range but we will hold off on that today in hopes of changing it out at the next visit.
