Appreciated the honesty of the tech and no sales pitch.
Used particle micrometer to count particulates in the home. Measured the particulants at the return vent and the downstairs supply vent in the living room. Measured the particulants in the kitchen and in the master bedroom.
Upon arrival performed maintenance on hvac system. Checked refrigerant levels system is operating at standards. Hardstart kit in working order. Primary and secondary motor controls in range. Indoor motor and wheel good. Circuit board and electrical connections in range. Ducts and seals good. Recommend adding surge protection to system. Opened up condenser and washed out coils. Temp split in range. Cycled system on and off. System was reset tested and fully functional upon departure.
Tech arrived on site to a 9 year old system. Coil was corroding due to the salt in the air. Did not use chemicals on coil. Hosed it down. Cleaned out electrical. Start components are rusting out. Amps were okay. Compressor start amps getting high. Recommend booster kit to lower. Charge and temp split is perfect. Static is good. Customer declined recommend repairs.
Tested heating system for operation and performed service maintenance. Tested thermostat and measured internal temperature rise. Recorded voltages and motor amp draws. Inspected gas piping. Tested ignitor and cleaned flame sensor. Measured combustion motor capacitor. Replaced filter.
Performed combo tune up on 8 year old Lennox system. Cycled system through heating and cooling modes. Checked indoor and outdoor unit electrical and system components. Homeowner just replaced his filter and it is clean. Heating components all check good. Blower wheel is starting to get dirty and accumulating dust. Recommended homeowner to upgrade his filter to a Merv 16 filter for better filtration. Temperature rise is within range in heat. Checked outdoor unit electrical and system components. Secondary motor control is within range. Primary motor control is in good condition. Refrigerant levels check ok and system is producing proper temperature split and cooling correctly. Pulled off all panels and condenser fan motor and thoroughly washed out condenser coil inside and out. Compressor amp draws are in range as well as condenser fan motor amps. Went over findings and recommendations. Cycled system, system is fully operational upon departure.
Performed diagnostic on 2012 Lennox system. Homeowner states that system is not cooling. Indoor unit is kicking on and blowing air, outdoor unit is not kicking on. Cycled system for cooling. Checked outdoor unit electrical and system components. System is recieving 24 volt command, but primary motor control is not engaging. Found that high pressure switch was triggered, which was not allowing voltage to pass through to kick system on. Condenser coil is completely clogged, which explains why high pressure switch was tripped. Pulled off all condenser panels as well as condenser fan motor and thoroughly washed out condenser coil inside and out. Reset high pressure switch. Primary motor control engaged and system kicked on normally. Amp draws for compressor and condenser fan motor are within range. Secondary motor control is within range. Refrigerant pressures are now good and system is producing proper temperature split. Filter that is inside unit is the incorrect size, advised homeowner
