Upon arrival found system heating supply temp at 99. House at 55 degrees set at 65. Checked all settings and tested system. Found blower foam packaging still attached to blower. Removed and retested. Supply temps now at 133. And running to standards.

Gas furnace tuneup on 2 furnaces . Checked the air filters and replaced supplied by the customer. Checked the wiring connections and the voltages . Flushed the drain lines and furnace traps and inspected the condensate pumps on both units. Inspected the burners and flame sensors and cleaned . Inspected both flue pipes for leaks and bellies. checked the thermostats in heating mode and checked the gas pressures and the furnace safeties. checked the motor amps on the inducer operation and blower motors. Took indoor heat temp rise and tested for combustion on both units . Both furnaces are in good working order at this time of service.

Estimate

Customer called in for no heat. There’s three systems in the house. One is the sunroom which is working fine the other two main floor and second floor not working properly. After troubleshooting both units for first and second floor systems found out that both of them have crack heat exchangers. Main floor system had a blocked filter unit kept going off on high limit. On second floor unit inducer assembly is seized and not working. Provided estimate for repairs. First floor system needs heat exchanger, second floor needs new heat exchanger and inducer assembly. Burn heaters are red tagged, from now on customer is liable and they want to continue running main floor system.

Perform six month inspection on a recently install heat pump for first floor. Everything checked out good on new unit replace air filter 18 x 18 by one. Supply return our temperatures 25° outside temperatures and refrigerant level was OK. Also perform check up on the second floor heat pump check electrical low and high voltage connections and components test 5KW electric heater replace filter supply return air temperatures outside refrigerant levels, capacitor contactor recycle unit test defrost. Unit is from 2006. Customer is aware of age and condition. Running little harder than normal.

Performed two heat pump tune ups. Small heat pump front lobby checked out ok replace filter check back up heat ok. Supply and return air ok. Refrigerant levels ok on dojo unit, found unit running on auxiliary heat. Outdoor heat pump locked out on low pressure error code. Replace all 3 filters test back up heat. Reset unit and check levels. Refrigerant levels are lower than normal. This explains why they received high electric bill. Provided estimate to add refrigerant and dye to find out where unit is leaking. Would consider getting an estimate to replace system due to past history on repairs. Office to follow up with customer.

Fully assessed breaker tripping on strap heater situation. Found outdoor defrost board not wired correctly. Connected white and brown wires at outdoor unit and wired Correctly indoor air handler. Ran outdoor defrost board through test mode and found that now it is energizing strip repeater at 43 A when running in defrost mode, which is correct. After talking to tenet the breaker on the strip heater has several Nuisance trips. Whould still recommend replacement of strip Heater and breaker. Talked to landlord he would like our office to just email him over the strip heater quote only.

No heat room 109. Made a call for heat. Indoor fan motor runs but no operation from compressor check compressor capacitor reading 25 MFD check resistant across all three leads between run and start 7.4 ohms common to start zero ohms common to run zero ohms. Told Bill that the compressor it’s open on overload I cannot check compressor winding because we will need to pull the whole unit apart to get to compressor terminals. Most likely compressor over load stuck open.

No heat found no power to unit. Check 15 amp fuse and was no good. Check wiring found compressor start terminal reading high ohms between S to C and R. Install new fuse and fuse went bad as soon as the power was restored to the unit. Bill will change this unit.

No heat room memory care center 16 found unit with no thermostat. Check wiring electrical low and high voltage, jump thermostat connections to test the heat, everything came on. Check supply and return air ok getting 24° differential plate between supply and return. Bill will install thermostat.

No heat, found unit with no power, bill reset breaker and test operation found capacitor to be at fault. Reading 0 mfd rated at 25 bill had spare capacitor on site. Replace capacitor and test unit operation ok supply air 94 return air 72 cycle unit couple times ok.

Completed plan member heat tune up for 100,000 BTU modulating natural gas furnace. Homeowner replaces filter, in good condition at this time Inspected burner, heat exchanger, inducer assembly, pressure switches Cleaned flame sensor with fine steel wool, verified flame rectification circuit Ignitor in good condition, measured correct ohms Cleared EZ trap, added treatment tabs to condensate pump Inspected wiring and controls, left estimate for ECM surge protector for blower motor Measured temperature rise and static pressure Combustion and draft tests: Pass System operating well at this time. Homeowner paid for plan today.

Customer has heat pump from 2012. Tenants states that some times heat pump would pump cold air. Based on customer explanation could determine where to start. Check emergency heat 10 kw ok. Run unit in heat mode refrigerant levels and temps ok. As I was running unit the breaker for air handler tripped it stemmed like this has happened in the past. Also noticed when heat pump goes into defrost it does not send signal back to indoor air handler, wires are wire nutted on outdoor and indoor unit. Based on what I’m able to see during today’s visit. Would recommend replacement of electric heater outdoor defrost and sensor, and wired unit based in manufacture specifications. Would recommend system upgrade as main option. Customer to decide.

Me and Jacob arrived on new boiler Install not heating correctly. On arrival we did find the boiler was running . We went into house and found the temperature set at 75° house temperature was 55° for both zones . We went back to the boiler. Noticed that boiler was making a call for domestic hot water More often than the house heating. I got a hold of tech-support and tech-support showed me how to check for water flow for a call for domestic. We are getting .28 water flow, which will activate the call for domestic. We did find that a toilet was piped backwards with hot water and was leaking at the flapper, causing the domestic to run more than normal. Right now the toilet is valved off so now the house is getting a call for heat. The customer has a plumber coming back to fix the toilet issue tomorrow. Everything is back up and running at this time with the boiler, and temps are rising. no charge for today from the recall .

Arrived at call for no heat and noticed thermostat was set for recovery mode on a schedule of 5 ht cycles an hour and when I removed the schedule the unit fired in at full capacity and heated right up, told customer to set the schedule closer together, he had it at 58 and 75 so it was taking forever to heat back up, tested radiators that were all at 140 degrees and boiler was at 160, set unit for 70 degrees and to hold so it would bypass thermostat.

Perform six month inspection on recently installed heat pump no questions from customer. Replace air filter. Check supply return air temperatures test 15 kw back up electric heat check outdoor unit electrical and refrigerant pressures. Check any active error codes on thermostat no codes were showing. Cycle heat pump OK

Pump down remaining refrigerant in the system. Disconnect and remove the Coil from the Air Handler. Install new Coil in the Air Handler and braze connections. Pressure test and evacuate system.

Heat tune up for 2 Ton communicating Heat pump with 10KW electric heat kit Replaced Aprilaire 313 filter provided by homeowner Indoor and outdoor coils in good condition Inspected wiring, controls, electric motors and components; control settings 10KW electric heat amps 38.8 Good Measured temperature rise and static pressure Verified integrity of compressor motor Checked defrost cycle/operation Verified refrigerant charge and pressures System is operating well at this time.

Fully assessed no heating situation. Found furnace had tripped rollout switch. Blower motor was not coming on. Found low voltage DC mole plug that inputs power to blower speeds seem to be loose. Pushed on connector and blower motor came on and heat is working correctly. System was recently installed. Todd wanted to increase his blower on speed tapping from tap one to tap two. Measured DC voltages at board. Tap one voltage to ground was 7.2 V DC. Tap five terminal which is energized during heating was 14 V DC. Explain to Todd that this might not be a good idea because it could damage the blower motor . He may call train himself to find out if this is possible. No charge as per recent install.
