Rated 4.8 out of 5 stars based on 4 customer reviews

Professional and reasonable prices

We've been using DiBiase for several years. They've always had competitive prices and are very professional. Brian was out today to perform a checkup. He was here almost an hour, and he appeared to actually do things. He's friendly and kept things clean.

Performed Quality Assurance on American Standard AC unit. Only inspected the outdoor unit because no one was home at the time. Corrected any issues that were found. Completed appropriate fields on the Checklist Form. I would not pass this installation. It looked nice from farther away, but the details of it were missing. For an AC and Coil install the minor details I listed on the checklist should have been completed.

Reclaimed and removed old ac and coil. Installed a new American standard coil on top of existing furnace. Adapted all supply ducting as needed , taped and sealed all duct. Installed a new condensate drain with a ez trap wired in.installed a new condensate pump with new vinyl tubing ran outside. Installed a new American standard ac unit on a new plastic pad . New disconnect box and electrical wiring to unit. Brazed all joints and leak checked with nitro and bubbles. Tested unit and it is working great.

Checked no cooling complaint and coil icing up. Checked air filter ok, checked refrigerant charge, found low on charge. Recommend replacing air conditioner vs repairs due to age and condition.

Service call that both the First Floor and Second Floor Systems were not operating. The First Floor Thermostat was calling for Cooling but the Indoor Temperature was at 79 Degrees. The system was not running due to the Safety Interlock Switch on the Condensation Pump being tripped which shut power off to the unit. Found the Vinyl Tubing for the Pump was clogged. Cleared the Vinyl Tubing and System began operating again. Filled Pump multiple times and tested operation. Measured Refrigerant Charge and found System to be slightly low on Charge. System is still Cooling with a 18-19 Degree Temperature Split but the Superheat Levels are higher than normal indicating that the system is below the recommended refrigerant level. System was calling for a 19 Degree Superheat and was running at a 40 Degree Superheat. Second Floor System was running but was not cooling. Measured Refrigerant Charge on system. The Compressor is running but is failing and is not pumping Refrigerant Through the system

Performed Precision AC Tune Up on the First Floor and Second Floor System. Replaced the Air Filter on the Second Floor System. Cleaned EZ Traps on both Systems and Condensation Pump. Inspected Electrical Components on Indoor and Outdoor Units. Measured Refrigerant Charge on both Systems. The First Floor System Refrigerant Levels were slightly off. Superheat Levels were higher at 26 Degrees and the Indoor Coil Temperature was around 33-34 Degrees. This indicates that the system is low on Refrigerant. Also found the Compressor is drawing high Amp readings. It is still within its rating of 19.7 Amps but is higher than normal at 17.1 Amps. This is an indication that the system is not running efficiently and the Compressor is worker harder to operate. While System is running and cooling, due to the Refrigerant levels being lower and the higher Amp readings of the Compressor, it would be recommended to begin planning for replacement of the First Floor System.

Performed cooling maintenance, checked air filters ok inspected cooling coils. Blew out condensate drain and cleaned condensate pump. Checked voltage, amperage and electrical connections, measured capacitor values ok. Started air conditioners, checked refrigerant charge, found second floor air conditioner low on charge. Topped off refrigerant charge on second floor air conditioner. Checked operation and temperature drop across coils. Need sales to quote for new second floor system

No ac found, unit off upon arrival, set thermostat to call for cool, noticed outdoor fan motor runs but no compressor, found open capacitor and short hard start relay, quoted for repairs, customer ok during repaors , noticed contactor high resistance getting 24 volts but not engaging sometimes informed customer about situation and installed new contactor cycle and test unit r22 pressure ok 180/70 supply temp 49 return air 71

Found locked up condenser fan moter, and 40/7.5 mf cap that needed replaced, bearings in moter had locked up. Replaced with rescue moter. Fan on old moter was rusted on shaft. Drilled and pressed off fan blade and installed on new moter. After installing checked pressures they were 223/60 r-22. Fan does have a slight shake to it when running this is caused by not a perfect balance but is not to be a concern. Ac is back working again.

Found second floor system leaking from the furnace, secondary heat exchanger. Water is leaking out of the appliance cabinet on to the second floor ceiling. Due to the age and application of the system, it is highly recommended to replace the propane gas furnace. Homeowners insurance should be contacted to see if the HVAC equipment can be covered under the homeowner insurance policy along with remediation and drywall repair. I also found a direct vent propane gas water heater leaking on to the basement floor. The hot water heater is past its average lifetime expectancy. The pressure relief valve and the expansion tank have failed. Which is causing water to leak on to the floor and the wood stud walls. Recommend replacing gas furnace asap to avoid future damage, repairs can not be done on this system and application in a cost effective manner.

Service call that the one of the Gas Furnaces for the Home was not working properly. Upon arrival found the First Floor Unit was not to Temperature but the Second Floor Unit was to Temperature. Found the First Floor Unit was running but was blowing Cold Air. Also found that the Auxilary Pan for the Second Floor Unit was full of Water. Began troubleshooting the First Floor Unit and found that the Limit Switch for the Burner Box was missing and the wiring was not connected to anything. This was causing the Furnace to think that a Limit Safety had opened and was causing the Fan to continually run. Called Manufacturer to get rating for the Limit Switch. Spoke with Jane who gave approval for the pricing to replace the Limit Switch. Also informed Jane of issue with the Second Floor System. Water was leaking from the Drain Tubing. Installed Clamps onto the Drain Tubes to seal and put system back in operation. The Went to Supply House to pick up the Limit Switch for the First Floor System.

Performed Precision Heat Tune Up on both the First Floor System and Second Floor Systems. Replaced both Air Filters. While testing Electrical Components on the First Floor System, found Blower Motor Capacitor was measuring below its rating. Spoke with Homeowner about Capacitor and Installed a new Blower Capacitor. Homeowner was concerned that the Humidifier for the First Floor System was not working. Found the Humdifier was Turned Off at the Humidistat Control and the Damper on the Humidifier was closed. Performed Humidifier Cleaning and Servicing. Tested operation of Humdifier and set Humidistat to 35%. Performed Combustion Analysis on Furnace. The Combustion Levels were slightly higher than recommended. The Gas Pressure could not be adjusted due to the Gas Valve being pinned at its highest level. Overall the First Floor System is in ok condition. Due to age and condition, recommend to begin planning for replacement of the First a Floor System in the Future. Performed Combustion Ana
