    Folks, I'm rebuilding my A/C recovery pump. I have never done one before but it seems pretty straightforward. Mine has the Robinair CP1320 compressor. Datasheets state that this machine is "oil-less." The rebuild instructions state to soak seals and o-rings in refrigerant oil. Other than...

    I've been having minor, periodic issues with my ac for a bit, but it always starts working right before I decide I need to call someone out. The gist of the issue is when the ac kicks on (typically in cooler weather or when it hasn't run in a while), the compressor starts then immediately...

    I have a new Senville 110v, 12,000 btu unit. Finished install and hookups. It blows the 20A circuit breaker whenever compressor tries to kick on. It will run the blower fan if I disconnect the compressor lines. Inside unit seems fine. I checked continuity on the three compressor lines, A,B,C...

    I have a Craftsman 150 PSI Compressor (Model: 919.167310). I just purchased a new Air Regulator to replace the original one that I thought had gone bad since it would drain the main tank pressure to whatever I set the Regulator pressure to. However, when I replaced the old reg with the new reg...

    My neighbor complained that the A/C is too loud and they are unable to sleep in the night. Our compressor is about 12 ft from the fence and their bedroom window is about 10-15 ft from the fence. The unit is Lennox that we bought last year. I bought a decibel meter and it measures around 60-62...

    Hello everyone, Two days ago, my attic unit was making crashing noises to the point where air flow completely stopped. After investigating, some of the blower wheel blades were broken and broke the wheel in general. After replacing the blower wheel with the exact same specs, the attic unit is...

    So I live in a college/University community and every year, regardless of viral disease and mayhem, the students throw away tons of furniture, appliances, and the infamous mii fridge. I've scooped a few over the years selling them on craigslist and the like. About 6 months ago I was coming home...

    A few days back, I found out that the fan of the HVAC system is running (fan inside is running and heating works fine) but the outside condenser unit is not running. The circuit breaker was tripped and whenever I switch on the circuit breaker, it trips again in 3-5 seconds. I changed the circuit...

    My AC has always worked fine. A couple months ago I replaced a battery powered thermostat with a Honeywell Wifi smart thermostat. The new thermostat needed a "C" wire for power and there was an unused dark blue wire behind the old thermostat so i connected it to the "C" port at the furnace...

    Not sure this is the right place. Our fridge started to cool less over the last few days. There is a clicking sound but neither the compressor or fan seems to be running. Tested both, as well as the starter relay with a multimeter, all compenents are fine and give appropriate readings.The coils...

    The other day I noticed that hot air was coming out of my vents when I had the A/C running. I went and looked at the condenser and the compressor was running but the fan was not and the fan motor was very hot. After doing some studying, I replace the cap and turned the A/C back on but the fan...

    I just replaced my condenser fan motor because the bearings were shot in my old one. My unit is a Keeprite KSSD 19-36, probably around 25 years old. The old motor had 4 wires, red, black, brown and white. The new motor's wires are yellow, black, brown, and brown/white. After I installed the...

    I just bought a small (3 gallon, 100 max PSI) Harbor Freight air compressor, and I'm trying to figure out what else I need to operate my 18-gauge brad nailer with it. The manual says to attach a regulator, which I don't understand because the compressor itself has a regulator that you can set to...

    Hello - I need to replace my 20 year old HVAC system and have about six different contractor quotes - ranging in price from about $5K to $10K. Many of the contractor/mfger websites I visited recommend the 2-stage compressors, but the cost difference between single stage (16 SEER) system...

    Is there any data out there that correlates AC compressor starting or running amps (vs. max rated values) with overall condition of the AC unit, compressor condition in particular. For example, I'm guessing that as a unit ages it's LRA & RLA with gradually increase...and begin to approach...

    Couple nights ago I noticed it was getting warm and muggy in the house. The a/c fan was running in the house, but the air coming out of the register wasn't cool. Went out to the yard and saw that the condenser fan wasn't running. Took the cover off and saw that the capacitor top was domed...
