Perform precision heat tuneup on 1989 carrier gas furnace. Replaced 16 x 25 x 1“ air filter. Clean flame sensor. Check gas pressure. Check temperature rise. Performed combustion test. After looking at furnace overall blower motor bearings rattle when it runs. Inducer motor also has some noise and control board has some signs of overheating. Would recommend replacement of gas furnace. Also customer did talk to me about The air dry in the home. Would recommend a humidifier when installing new furnace will talk it over with his wife and will give us a call when they’re ready. Furnace is working at time of service., No guarantee on continuing to stay working.

Rooftop unit not heating found blower running but no operation from the heater. Found unit locked out on high-limit error code. Inspect belt, air filters and heat exchanger found all four filters completely clogged restricting 100% air flow, belt It’s all worn out and heat exchanger has holes. Took photos of all items. Unit can’t be runnng under these conditions. Repairs are needed immediately for the unit to be running in safe condition. Provided estimate for repairs.

Arrived to unit claiming for heat to 73° but thermostat on 67°. Came into basement and saw heat running but no blower. Inspected heat exchanger and flame sensor. By flame sensor unit appeared to have been short cycling. Checked blower capacitor and it was 8.9/10. Made a call for fan and the blower motor did not come on. Checked my voltage from control board and it was 0. Shut down unit and tested motor on door switch. Blower came on. Unit has a bad control board. Homeowner was with me and I told him control board and labor was around $1000. Unit is 25 years old furnace and ac. R22 refrigerant which is no longer made. He doesn’t want to make an investment in a unit that old. Would like someone to come out and give him pricing options on replacement. Jumped blower to door switch for temporary heat until replacement.

The following proposal details the recommended upgrades for improving the comfort and air quality of the basement, as well as increasing the comfort and efficiency of the home overall via home performance upgrades in the attic spaces.

Found bathroom exhaust fan locked up. Got our office to run out new exhaust fan. Installed and tested operation. Fan is nice and quiet and working fine again.

No heat for unit 101. Bill, replace unit from an existing working location but still not working upon arrival found mercury style thermostat set to heat but no operation to the motherboard. No heat call to board. Jumper wires at the thermostat base and unit came on test heat and cool OK Replace customer supply thermostat test operation at the thermostat. System is working now providing heat.

Performed tune up on Amana heat pump, ran system in emergency heat mode and checked heat strips and electrical components as well as temperature split and blower motor and coil. Went to the outdoor unit and inspected all electrical and mechanical components, checked capacitor and compressor as well as refrigerant levels and outdoor fan motor. No issues with unit at this time.

Check operation of the unit found open eight amp high voltage fuse to fuse from an extra unit that Bill had at the office test. Found blower motor to be defective. Bill replace blower motor and test operation.. rewire thermostat so it energizes reversible valve on heat after all the repairs test system operation system is now heating.

Upon arrival bill told me the high volt fuse fried and blower motor. He replaced blower motor and fuse. Still nothing he said. I checked fuse it was still ok. Was getting power to the board. I noticed one leg has 287 one leg has 0 and ground. Never saw this before and couldn’t find and information on unit. Called islandaire at 2:30 and waited for a return call. Never called back. I dug deeper into it and found the fuse on board blown. Fuse model number “582”. Bill is going to order some of these fuses. I think we need to get these fuses and speak to islandaire. It’s a 277 volt unit. So should have around 140 on each leg. But I did notice on board it say L2(N). I don’t want to mess with anything until I speak to them. Unit does say nema 6-15 plug which has the voltage on both legs. Will follow up after speaking to islandaire and bill receives fuses.

Unit was in operation when I got here. Homeowner said he had to mess with vinyl on pump this morning. I turned off unit and went to remove pump to inspect it. The safety wires immediately fell apart and wire nut fell off. They had the orange wire nuts on them and not put together well. Stripped all wires and put on blue wire nuts. Added condensate tabs as well. Wired unit back up and tested operation. Pulled on condensate wires and shook pump. No issues. Seems like it was just a loose safety wire.

Completed heat tune up for 2 ton heat pump with 10KW electric heat kit. Aprilaire 401 filter in good condition. Humidifier pad in good condition. Checked operations. Inspected wiring and controls. Verified proper amp draw of 10KW heat kit. 40A Good. Outdoor equipment has surge protection. Indoor equipment does not. Left estimate for blower motor surge protector. After discussing, homeowner agreed to estimate. I completed work and tested today. Indoor and outdoor coils clean Inspected drain and EZ trap. Measured temperature rise and static pressure Verified integrity of compressor motor. Confirmed refrigerant charge/pressures System operating well at this time. Homeowner paid for plan renewal and EXM surge protector today.

Arrived for no heat we are just here yesterday and had told the customer that he would need electrician. The Electrician apparently found no problem with their side of power . I came out to look at the equipment. I had 120 V coming to the receptacle. I checked my wire nuts and the wiring at the furnace coming in from the receptacle and had no 120 volts . I took apart the 4x4 box For the switch and receptacle and found a very loose neutral from the furnace that was barely connected and causing arcing. I Stripped the neutral wire back put new wire nuts and tighten all connections . I Turned the system back on and tested the furnace , it came back on and and started producing heat. The system is back up and running at this time of service, no charge for recall.

Performed QA on Trane Heat Pump/Air Handler install. Reviewed installation with homeowner. She mentioned that there was a noise coming from the return register in the hallway. She also mentioned that before her old system had low airflow everywhere and now some vents have a lot of air and other are still lower. When I went into the attic I checked all of the take offs and none of the, have dampers installed to adjust/balance airflow. Also found they used R-4 Flex in the attic instead of R-8. Checked the return filter grills and the filters need to be changed. Also found she is using MERV-10 or higher filters. Let her know to not use above MERV-8 filters and to see if that stops the noise. She is going to order new filters and change herself. Filter sizes are: 12x12x1 and 12x20x. Also let her know about the dampers and the ductwork in the attic. I recommended that she have all the ductwork reinsulated and new flex duct ran with dampers installed. She said she is fine for now with how th

Upon arrival Tom told me that he had an electrician here installing a dimmer switch yesterday. I came to unit and noticed furnace had power but no led. Traced out power and neutral. Found neutral with 120v in spots and 1.8volts in other spots it is back feeding from panel. If I pull neutral off board and jump n terminal to ground unit runs. I looked in panel and furnace is still hooked up to furnace breaker correctly. Need to have the electrician return from this point.
