Good service all around, explained what needed to be done and how much cost would be. I was disappointed that his boss told him to forego injecting dye into the system to check for leaks since he seemed to have fixed the problem. I am selling the house and would much prefer the peace of mind knowing that there are positively no more leaks.

Upon arrival inspected system and found in limit failure inspected limit and limit was physically blown and would not reclose. Replace with truck stock same temperatures. Test run heat unit operational at this time
Upon arrival, inspected systems and did not find any concerns with HVAC systems. Checked ohms for wiring supplying disconnects and found a few wires with direct shorts to ground reading 0.0 and a few wires with .60 ohms on them. OL on all wires supply HVAC units. No issues discovered with hvac equipment errors are internal in the electrical supply
Electric heating maintenance inspection performed Inspect filter:16x25x4 new today Inspect electrical components Turn on electric heat at thermostat Check volt and amps draw on each element Blower Motor amps: 4.05 All wiring OK Humidifier: panel new today water panel #10 Temperature rise for electric heat: 43⁰ Electric heat is running in optimum conditions.
Performed heating maintenance on a 2011 Carrier Infinty 3 stage 97% efficient natural gas furnace Replaced humidifier water panel (aprilaire #10) 16x25x4 filter is still good Pulled flame sensor and cleaned Pulled condensate trap and flushed with water Blower wheel is clean Burners are in good shape Run tested furnace while performing combustion test and checking temperature rise High fire set to 3.7" Med fire set to 1.75" Low fire set to 0.65" No concerns found
Gas heating preventative maintenance performed Check filter - 20x25x1 due soon Clean flame sensor Ohm test igniter: 65.3 ohms Inspect wiring for loose connections and/or hot spots - no concerns Inspect exhaust flu - no concerns Set thermostat for heat Check amp draw on blower motor: 4.31 Check amp draw on inducer motor:0.93 Check delta T - 61° Furnace is in optimal running conditions
Disconnect switch (standard light switch) failed Bypassed the switch Breaker #3 in the kitchen controls the furnace Quote single zone mini split for 400sqft addition on the back of the house. May need an electrician to run power to it May also be able to put a junction box off the current AC disconnect. It's on a 40A Breaker and the min ampacity is 16.6A
Gas heating preventative maintenance performed Check filter - 16x25x1 new today Clean flame sensor Ohm test igniter: spark n/a no concerns Inspect wiring for loose connections and/or hot spots - none found Inspect exhaust flu - no concerns 4” round Set thermostat for heat Check amp draw on inducer motor: 1.0 Check delta T - 50° running hot building at 78° upon arrival Furnace is in optimal running conditions
Explained thermostat operation Mode button needs pressed to change between heat and cool settings Performed maintenance on gas furnace Pulled and cleaned flame sensor Adjusted gas pressure to 3.2"wc Filter is in good shape Blower is clean Drain is clear Exhaust venting is in good shape No concerns found with the furnace
Adjusted blower sheave on RTU 3 to maximum blower speed Had to adjust belt tension to not have belt too tight Installed new belt provided by Jeff. Two split systems for front offices at the main entrance had blower speeds both set to medium-high. Moved both of them to high speed. Small packaged unit on the low roof north of the main entrance: increased blower speed to high.
New expansion valve restricted from system contamination Contaminated due to the hole in the outdoor unit being open for many months.
Replaced expansion valve under parts warranty.
Service recall Refrigerant charge still good Suction pressure low, superheat high Removed txv sensing bulb and heated with a lighter No change in pressure or superheat Signed estimate for non-warranty txv, but it may still have parts warranty.
Replace filters on each unit Wash condenser coils for each unit. Test run cooling operation and verify delta T on each system Flush drain traps on each unit Verify capacitance for each system with capacitors Replace pulley on #2 motor to reduce condensation by speeding airflow up. All systems in good health at this time found no errors.
Service warranty System running 8⁰ subcool Washed filter Adjusted blower speed to a higher rate
Upon arrival inspected thermostat and didn’t find obvious concerns, inspected air handler and found no concerns. Inspected rooftop and found unit running in heat pump function and reversing valve not actuated. Went through thermostat programming and found thermostat programmed for gas heat not heat pump so unit was running heat pump instead of AC. Reprogram and test run unit. Unit is properly cooling now.
