5 Star HVAC Contractor in Elkton, MD

Completed comfort call inspection of residential HVAC system located in attic space. Documented existing air handler unit with associated ductwork, refrigerant lines, and electrical connections. All components appeared to be functioning within normal parameters, with reflective insulated ductwork properly installed and fiberglass insulation present between floor joists throughout the attic space.

I successfully installed a new air conditioning unit, ensuring it was properly sized for the space. The installation involved mounting the outdoor condenser unit securely and connecting it to the indoor evaporator coil. I meticulously ran and insulated the necessary refrigerant lines, ensuring no leaks. The indoor coil was installed in the designated area, and the necessary ductwork was connected to facilitate efficient airflow. After the installation, I performed a thorough system check to confirm optimal performance and energy efficiency. The new air conditioning system is now fully operational, providing enhanced comfort.

I conducted a comprehensive rejuvenation of the AC system, ensuring optimal performance. The system was thoroughly cleaned, and all components were tested. The AC is now operating efficiently with no major concerns. I advised the customer to acquire additional filters and to change them more frequently, recommending no higher than a MERV 10 filter. I also identified a potential issue with water dripping from the fresh air intake into the furnace, which could lead to problems. A small water buildup inside the furnace cabinet was addressed. Measurements showed a Delta T of 19, MEG refrigerant system at 1000/1000, MEG air circulation system at 1000/1000, and a voltage enhancement system within range. The drain line was cleared, and both the outdoor and indoor coils were cleaned.

I performed comprehensive maintenance on a one-to-one mini split head and outdoor system, along with rejuvenating a furnace. The mini split system achieved a 20-degree delta T. The filters were already clean, so they were not taken outside for cleaning. I removed the hard white plastic cover and cleaned it. The evaporator coil was lightly brushed to remove trapped debris. The condensate system was tested and found operational. For the outdoor unit, I ensured it ran in cooling mode with voltages at 244v. I sprayed the coil to clear debris and cleaned the cover. The furnace ignited after the second try, with a voltage reading of 119v. The heat exchanger was tested and inspected, and further testing confirmed it was in good condition. I identified air contamination around the unit and made small repairs to limit air leakage. A gas leak detector pinpointed the manifold valve as the source of the leak, which I recommend replacing before using the furnace for heat. The outdoor unit ran in c

Upon arrival, I inspected the system and found low airflow from several supply vents. The indoor unit showed excessive condensation on the ductwork and evaporator coil cabinet. The refrigerant line set was frozen, with ice buildup and water dripping from condensation. The entire system was frozen, hindering proper airflow and cooling. The system needs to thaw completely before further diagnostics. Once thawed, I will conduct a refrigerant leak inspection and evaluate system performance to identify the cause of the freeze-up and necessary repairs.

Upon arrival, I conducted a thorough inspection of the electrical components, ensuring all specifications were met and confirming that the system was charged correctly. I then assessed the head pressure, discovering it was higher than the recommended range. I provided a detailed quote for coil cleaning to address this issue. Although the customer chose not to proceed with the quote, I reassured them that the AC system was operational. I explained the importance of addressing the high head pressure to prevent potential future issues and offered to schedule a follow-up visit if needed. The customer appreciated the detailed explanation and left satisfied with the current functionality of their AC system.

Job WO-TNFR697430 involved a comprehensive heat transfer rejuvenation process. I meticulously inspected the system, identified areas of wear, and executed precise rejuvenation techniques. This included cleaning, realigning components, and ensuring optimal performance. I also educated the client on the importance of regular maintenance to prevent future issues and costly repairs.

Upon arrival, the air conditioning was operational and the thermostat was set correctly. I thoroughly cleaned the oil furnace, replacing the oil filter, pump strainer, and oil nozzle. I also cleaned the heat exchanger openings. I verified the oil pump pressure and confirmed a 50°F temperature rise. Using a combustion analyzer, I ran the heater and ensured all system operations were normal. I recommend an oil tank treatment for winter preparation and suggest duct cleaning. See attached estimates.
