My AC broke

Our AC broke and we were not able to figure out what happened. I was recommended DiBiase by my general contractor. So I called them. Nicole was pleasant to talk to and explained their process clearly. Their technician Nathan came on time and fixed the issue and was courteous to talk to. We were happy with the results.

Punctual, professional and thorough

My wife and I have come to expect complete professionalism and reliability from the DiBiase team. They reach out proactively to schedule seasonal check-ups and show up on time. The technicians are always good people and know what they're doing. Our HVAC system is approaching 20 years old, so we have regular discussions about its limited life expectancy, but they do their best to keep it running as efficiently as possible.

Performed six month quality check on a mini split and air conditioner, cleaned mini split air filter. Cycled thru heat cycle and cooling cycle, checked refrigerant charge. Checked main house air conditioner, replaced air filter. Tested water safety’s. Started air conditioner, balanced refrigerant charge. Checked operation and temperature drop across coil Checked stairway defuser, found hanging by the flex. Tried to install but the plastic and framing is preventing the defuser to catch the ears to the plaster. Will need a different style of mounting the defuser.

Found that after checking out the de-humidifier was functioning correctly. Washed off wasable filter again. Found de-humidifier set at 40%. Found humidity inside the home was reading 55% on Ecobee thermostat on first floor. Down in crawl space at the de-humidifier unit it was reading 43 %. Checked the humidity with a psycrometer. Was reading 52%. Found that at the air handler in garage the filter box was not completely sealed. Tapped around filter door to not pull humidity from the garage. Recommend to homeowner that if he really wants to help with the humidity levels during the summer months a new heat pump with variable speed blower and 2 stage compressor would help with reducing humidity levels in side the home. Homeowner is not ready to replace the system at this time. Recommend he keep his thermostat set at 70 degrees for a/c to run more often. Also a return was removed by a previous contractor.

Performed Quality Assurance on customer supplied ductless units. Measured supply and return air temperatures on both units. Checked drain lines on both units. Completed checklist form in system. Reviewed installation with owner. Did not go into attic space due to the room being used for the infants while I was there. Both systems are operating well at time of visit and they said units have been working well since installation.

Performed Precision AC Tune Up on Carrier Communicating system. Replaced the right side 20x25x4 Filter provided by the homeowner. Homeowner ordered additional filters and will replace the left side filter when they arrive. Cleaned Pump and AC drain Line. Filled pump and tested. Found vinyl tubing is dirty and corroded. Also found Condensation Pump working but motor sounds weak. Spoke to homeowner about concern with the pump and tubing and provided an estimate for replacement. Tested refrigerant charge and measured Air Temperatures. While testing system, found the Outdoor Fan Capacitor was testing below rating. Installed a new 7.5 Mfd Fan Capacitor for the Outdoor Unit and tested operation. System is operating but is about 14 years old. Due to overall conditions and previous issues with system, would recommend to begin planning for replacement of system before any major issues occur.

Returned to the job to open the gas valve on the manifold for the oven, found that the Best Buy geek squad broke their gas line and it was leaking. Our end of the gas line was bubble tested on both ends and found no leaks. We shut off the valve that is behind the oven and left the manifold side gas valve open for when geek squad comes back to replace their gas line, they just have to turn on the valve at the oven when it’s fixed. Also we added more hangers to the flu pipe and intake pipe so that they are now at lease 4 feet apart on the whole pipe.

Performed Quality Assurance inspection on a newly installed gas furnace and air conditioning system. This was an oil to gas conversion. System install looks really good. Small corrections while here. See notes in QA form. System running really good. Also met code inspector to complete permit for install. Code inspector only noted two things Venting piping needs hangers every 4 feet at minimum. Need to only add 3 hangers Locking Schrader caps on all outdoor units. Need to add locking Schrader caps. Code inspector passed the installation. No other inspection required. At 6 month inspection please have them add hangers to venting piping and put locking Schrader caps on outdoor unit.

Arrived at customers home and greeted them at the door. Spoke to Molly about the noise they have been experiencing. Sound is basically a ticking or tinging noise originally when system shutoff but seems to be while running too. She said they had a noise like that on the old system too but seems to be more now. Had Molly turn up the thermostat and proceeded to the basement. System started smoothly and flame looks good. Gas pressure is normal. Did start to hear this noise during run time. Turned system off and listened for noise. Found noise inside furnace and ductwork. Noise I was experiencing is thermal cooling of exchanger and ductwork near furnace. The system at that test was in 1st stage. Turned system on again and tested in full stage. Again smooth startup. Heard noise again during run time and on shutdown of blower. Adjusted air settings in cool cloud app and raised air flow during run time and extended blower shutdown timing. Ran system again and didn’t really notice during run
