Heating and Cooling Brownstown Township

Provided comprehensive estimate for complete air conditioning system replacement at residential property with non-functional outdoor condensing unit over 10 years old located exterior to basement installation with natural gas furnace. Assessed existing equipment condition including weathered condenser unit with fan assembly, electrical disconnect box, refrigerant line sets, and condensate drainage system mounted against brick exterior wall. Prepared replacement specifications for new cooling system compatible with existing natural gas heating infrastructure.

Responded to service call for non-operational air conditioning system on recent installation. Upon arrival, performed comprehensive system diagnostics using digital manifold gauges and temperature sensors. Inspection revealed system was in vacuum state with both suction and discharge pressures reading -61.3 PSIG, indicating complete refrigerant loss or system not properly charged during initial installation. Conducted thorough leak check of all refrigerant lines, connections, and components. Removed access panel to inspect interior furnace components and verify proper installation of refrigerant lines and electrical connections. Verified all wiring connections to gas valves, control boards, and safety devices were secure. Measured system airflow temperatures with return dry bulb at 79.4°F, return wet bulb at 65.5°F, supply dry bulb at 54.6°F, and supply wet bulb at 51.5°F using calibrated digital instruments. Evacuated system to proper vacuum levels, pressure tested for leaks, and re

Successfully completed installation of a 3.5-ton air conditioning condenser unit and evaporator coil system in rear yard location. The outdoor condenser was positioned on a protective pad adjacent to the residence with proper refrigerant line connections, electrical conduit routing, and disconnect box mounted to exterior wall. Inside, the evaporator coil was integrated with the existing air handler unit, with all necessary ductwork connections completed. All mechanical, electrical, and air conditioning permits were secured prior to installation, and electrical work was coordinated as required for system reconnection and proper operation.

Provided comprehensive estimate for complete HVAC system replacement including non-functional air conditioning unit and natural gas furnace located in basement. Existing equipment over 10 years old with outdoor condensing unit mounted on exterior brick wall connected to weatherproof electrical disconnect box via refrigerant line set. Assessed current installation configuration, electrical service capacity, and existing refrigerant line routing to develop replacement specifications for new high-efficiency cooling and heating system.

Provided comprehensive estimate for complete air conditioning system replacement of 25-year-old outdoor unit that ceased operation last year. Unit located on side of house shows significant weathering, age-related deterioration, and discoloration on exterior surfaces. Assessed existing installation including copper refrigerant lines, electrical disconnect box, mounting pad condition, and associated electrical conduit system for replacement planning considerations.

Completed system start-up on newly installed Lennox air conditioning unit with outdoor condenser positioned on concrete pad and evaporator coil installed in basement. Verified proper operation of condenser fan, confirmed refrigerant charge, and ensured all electrical connections and controls were functioning correctly. Unit is operating within manufacturer specifications and ready for service.

Performed diagnostic inspection of 22-year-old basement furnace that was blowing cold air, confirming DTE's assessment that replacement is necessary. Visual inspection revealed aging components and inefficient operation of the existing unit, which is connected to standard metal ductwork and PVC ventilation system. Documented current thermostat (showing 68°F) for compatibility considerations with replacement system.

Successfully completed installation of a complete HVAC system including a 110,000 BTU furnace, 4-ton AC unit, and whole-home humidifier with proper mechanical and electrical connections. System features a Lennox S40 smart thermostat with humidity control and temperature monitoring capabilities, and all necessary ductwork was properly connected with appropriate PVC venting installed according to manufacturer specifications.

Conducted an estimate for replacement options on a 1999 HVAC system with multiple failures including seized blower motor and grinding inducer motor resulting in no heat. Presented customer with replacement options for furnace-only and complete furnace/AC system configurations, with additional humidifier installation options for both scenarios. System is located in basement of brick residential structure with existing outdoor condenser unit positioned on concrete pad against exterior wall.

Responded to service call for furnace making loud noise in basement. Performed combustion analysis with Bacharach analyzer showing elevated CO(O) levels at 214 ppm and excess air at 81.7%. Conducted electrical diagnostics with multimeter to identify and resolve the issue causing the noise.
