professional, prompt, respectful, knowledgeable

Kurt was very helpful - as always. Quick response to an emergency was much appreciated. However, I only wish that a member of the DiBiase home service team had strongly recommended to us (prior) to deploy the new Ez trap with the safety valve shut-off float; if we had that unit inserted (prior) we would not have incurred the very significant flooring repair/replacement cost that we now face due to water damage!

Great Service

Many thanks to DiBiase Heating and Cooling for sending Luis to service our A/C unit after working hours. Luis was very informative right from our phone conversation. Once on the scene he diagnosed the problem and stated what the cost would be. He completed the task and tested the unit in timely manner and we were cool once again.Highly recommend Joe DiBiase and his team.

Highly recommended

Technician Luis Tenorio was amazing. He did thorough checking and change our old ugly looking thermostat to new brand one. They are well priced and do the quality work.

Great Air for a Dental Office

The crew came in and cleaned up my entire heating and air conditioning system as well as installing air scrubbers for additional safety during the Corona Virus pandemic. They were neat, careful and they stuck to the agreed pricing with no pressure for upsells. Very professional and knowledgeable outfit.

Found that at end of 3/8” vinyl hose there was a piece of copper to weigh down the line. Found that after talking to homeowner that the pump whould kick on and off on and off pump was overflowing. Removed copper from end of line and water began to flow freely. Told homeowner that it will take several days for all the water to dry up. Cleared blockage and tested condensation pump. Back up and working fine again.

Performed cooling maintenance, checked air filters. Blew out condensate traps and drains. Checked voltage, amperage and electrical connections, measured capacitor values. Started air conditioners, checked refrigerant charge, found first floor air conditioner low on charge. Topped off charge and balanced by superheat. Checked operation and temperature drop across coils.

Performed Quality Assurance inspection on a newly installed 3 headed ductless system. Checked level of all three heads. All good. Outdoor unit and disconnect level. Operating great at time of QA. Indoor head that was leaking stopped yesterday. Investigated the leak issue. Condensate drain looks to be pitched properly. Customer said it was leaking mainly during storm. Checked drain outside. Drain terminates close to the ground. Poured water into indoor head and pan filled up with water and drained extremely slow. Went back out and sucked on end of drain and had restriction then suddenly bunch of debris came out. Debris more than likely blew up drain from tropical storm and clogged drain. Poured 16oz of water into head again and this time drain pan kept up and drained properly. Did raise up drain off the ground some. If water leak happens again we will need to take down line hide and inspect further.

Found water all over the floor in kitchen next to where air handler sits. Found water backed up in condensation line. Also found that it taps into sewer pipe. No what we don’t know is if 2” pipe was clogged or just condensation drain line but blew out with nitrogen. Suggested we install the new ez trap with float switch for water protection. Installed ez trap with float and tested with several gallons of water drain is now taking water. Put a/c back into operation. Told homeowner it will take a long time for all the water to dry up under the flooring.

Noise coming from outside unit, found unit off upon arrival, informed customer to set thermostat to 65 ac mode, check ac operation, after a minute of running unit started making noise, noise is coming compressor, compressor is making grinding noise when it runs, check refrigerant cycle, pressures r22 are 200/70, noticed line set has two liquid line filter driers, one of them could be damaged that could’ve cost compressor failure, piston as meter device, based on today’s findings final diagnostic malfunctioning compressor, new compressor is needed, removed old filter driers and installed New filter drier...emailed proposal to make repairs, due to high costs in repair And unit being r22 would recommend replacing system

Service call that the AC was not cooling and the Auxiliary drain pan underneath the air handler was full of water. Upon arrival found system turned off. Proceeded to air handler to troubleshoot. Vacuumed water out of auxiliary drain pan and poured water into Coil Pan to test drain line. After pouring water through pan multiple times found a crack on the Drain Pan Fitting. Removed the PVC drain line and found the Coil Drain Connection was broken and pieces of the threaded fitting could be removed. Spoke to homeowner about issue. At this time she decline attempting to fix the fitting, and she does not want to operate the AC until it can be repaired. We will call the manufacturer tomorrow and get pricing to replace the Coil and Drain Pan. Air Handler is a Whirlpool. The AC is shut off at the main breaker panel and the Blower Fan is set to on.

Found nothing running, found ez- trap clogged and filter is very dirty. Let Lynn know the situation. Un- clog drain and replaced 20x25x1 air filter. Poured water down drain to test. Checked temperature split at indoor unit. Had a 21 degree temperature split. Checked r410 a pressures at 93 degrees outside air temp. Pressures were 263/141 with 9 degrees of subcooling. System is working fine at time of service.

Found when I first arrived compressor was not pumping at all , checked compressor amp draw with a meter and found compressor having an amp draw of 0. Had to cool down compressor with garden hose to be able to get compressor running again. Explained to homeowner that when a system is low on charge compressor is not receiving adequate oil from the refrigerant. After getting compressor to run at 6.9 amps added 1 lb 14ozs of r-22. Now refrigerant pressures are 190/75 with 7 degrees of subcooling, system is cooling at time of service but explained to homeowner that we do not know how long charge will last in the system.
