Trusted HVAC Specialists in Davenport, FL

Performed a complete evaporator coil pull-out and cleaning service. I pumped the refrigerant down into the outdoor condenser, removed the evaporator coil, and chemically cleaned it using evaporator coil cleaner. The coil was thoroughly rinsed and reinstalled. I also removed and cleaned the blower wheel and performed a microbial sanitizing treatment on the air handler cabinet, evaporator coil, blower wheel, and return area. Installed surge protectors at both the indoor air handler and outdoor condenser. Replaced the filter-drier, evacuated the system, and achieved a vacuum of 198 microns. I then released the refrigerant back into the system and checked the system operation. The customer provided a new air filter, which was also installed. Additionally, I installed a separate transformer for the UV light, as recommended, to prevent the UV light from being powered directly through the air handler circuit. After completing all work, I checked system operation and verified that the sys

Performed a diagnostic on a Goodman air conditioning system, approximately 4 years old. Customer stated they previously cleaned the system drain line because the drain was clogged. Customer also replaced the dual capacitor themselves. I checked the complete system operation and found the unit cooling at this time. I checked the system pressures, subcooling, superheat, and temperature split. The system is equipped with a piston metering device, not a TXV. The manufacturer target is approximately 10°F subcooling, while the system was reading 5.4°F subcooling. The measured temperature split was 78°F return air / 56°F supply air, for a 22°F delta T. During the equipment inspection, I found the blower wheel dirty, the condenser coil dirty, and the contactor pitted. The refrigerant charge also needs to be adjusted to bring the system within the manufacturer’s specifications. I provided the customer with a proposal for the recommended repairs and with a maintenance agreement. Customer req

Performed preventive maintenance contract on Carrier system, which is currently out of the manufacturer’s warranty period. Checked system operation in cooling mode, including system pressures, subcooling, superheat, temperature split, compressor amperage, condenser fan motor amperage, and blower motor amperage. All readings are within acceptable range, and the system is cooling properly at this time. Indoor humidity is also at an acceptable level. Inspected all electrical components. The capacitor and contactor are in good condition, and no electrical issues were found at this time. Tested the system’s safety float switch and confirmed that it is operating properly. No issues were found with the system pressures, amperage, or overall operation. Performed maintenance on the drain system by cleaning the drain line and drain pan and adding Viper treatment. Removed debris from inside the condenser and rinsed the condenser coil. During the unit inspection, found bacterial growth undernea

Recommend replacing the safety switch because it is a critical protection device designed to shut the system down in unsafe conditions (such as a clogged drain or overflow). If it is not working, the system could continue running and potentially cause water damage or other issues. Recommend replacing the contactor due to visible pitting on the contacts. Pitting is a sign of wear from electrical arcing, which can lead to poor electrical connection, overheating, or eventual failure that could cause the system to stop running. Also recommend surge protection for both the indoor and outdoor units to help protect sensitive electrical components from voltage spikes which can cause costly damage to boards, motors, and other parts.

Performed a diagnostic on an 11-year-old Carrier 3-ton system. Upon arrival, found the system drain line completely clogged. The safety float/flow switch did not shut the system down, causing the return flex duct to fill with water. Water had also leaked onto the garage floor. The return flex duct had detached from the collar and was saturated with water. I cleaned the system drain line and removed the water from the return flex at no charge. I attempted to address the disconnected duct, but the flex is too heavy and wet to safely reattach to the collar at this time. The system is temporarily operating and cooling, although it is currently pulling some return air from the garage and blowing some cool air into the house. The system and platform are in poor overall condition, with significant deterioration and bacterial growth present. Due to the age and condition of the equipment, the customer requested a proposal for a complete system replacement. I contacted the office and created

Performed preventive maintenance contract and checked system operation in cooling mode. Checked system pressures, subcooling, superheat, temperature split, compressor amperage, condenser fan motor amperage, and blower motor amperage. System is cooling properly and operating well at this time. Inspected the electrical components. Contactor is in good condition, and capacitor is within manufacturer specifications. Performed a complete unit inspection and found significant microbial growth inside the air handler cabinet and on the blower wheel. No surge protector or UV light was installed on the equipment. I recommend removing and thoroughly cleaning the blower wheel to help restore proper airflow and bring the system closer to manufacturer specifications. I also recommend microbial sanitization of the air handler cabinet and blower wheel. Recommended installation of a UV light to help prevent future microbial and bacterial growth inside the air handler cabinet, as well as surge protec

Customer requested to enroll in the Arctic Maintenance Agreement. Credit card information was already on file, so I proceeded with enrollment in the maintenance agreement. As part of the Arctic Maintenance Agreement, I completed the summer tune-up, including cleaning the condensate drain line and drain pan, flushing the drain line with approximately four gallons of hot water, applying biocide treatment to the drain pan, checking the temperature split, and inspecting the air filter. The temperature split was within the proper operating range. The air filter needs to be replaced ASAP; no spare filter was available in the garage. Property management should be notified regarding the filter replacement. The system was restarted after service and is operating properly and cooling at this time.

Performed preventive maintenance under the maintenance agreement. Cleaned and flushed the condensate drain line and drain pan using a drain snake to scrub the inside of the drain line, followed by a 4-gallon hot-water flush. Applied Viper treatment to the drain pan and drain line. Rinsed the condenser coil. Verified system operation and checked compressor amperage, condenser fan motor amperage, blower motor amperage, refrigerant pressures, subcooling, superheat, and temperature split. All readings are within acceptable operating range at this time. Checked the air filter; filter is currently in good condition. Customer reported significant air leakage from the evaporator coil cover. Found a missing screw at the platform and only three screws securing the front evaporator coil cover. Secured the front coil cover and lower panel properly to reduce air leakage and ensure the panels are secured. Recommendations: * Pull and clean the evaporator coil due to visible bacterial growth and d

Performed diagnostic on 2019 Goodman 3.5-ton system. Customer stated Del-Air previously diagnosed a bad compressor, bad capacitor, and leaking evaporator coil. Checked system operation and refrigerant pressures; pressures are below manufacturer specifications. Capacitor tested within tolerance, temperature split is normal, and air filter is clean. Found pitted contactor, evaporator coil approximately 50% compacted with debris, and dirty blower wheel. Customer approved contactor replacement and a return visit to perform a pull-out cleaning of the evaporator coil and blower wheel. Customer also enrolled in the Club Club Maintenance Membership. Replaced the contactor today. System is currently operating and draining properly. Recommend performing leak detection on the return visit, as customer stated Del-Air has never performed a leak check on the system.
