Great Service - Full System Replacement

We recently purchased a home with a 20+ year old system that needed to be replaced. Based on a recommendation from a friend we reached out to DiBiase. The quoting process was simple and straightforward and I appreciated the multiple quotes using the good, better, best categories to help make a decision. Everyone we spoke to was polite and answered all of our (many) questions and the install was done to our complete satisfaction. I would highly recommend them.

219 Sylvan Drive attn to detail missed

The technicians were courteous and professional but there were several issues with the quality of work performed that I observed after work was complete. 1. Dust and woodchip debris from a board sawed by the technician was left in a pile where it fell in our basement. 2. An elbow duct joining a main duct had a large gap that was neither screwed nor taped and one could feel air being lost through this large gap. 3. Other joints/connections in ductwork where one would expect there to be tape there was none and one could feel air being lost. 4. A new electric line that had to be run from the thermostat to the new furnace was not stapled to the ceiling joist in the basement but was left hanging. 5. Two large holes had to be drilled through our block walls in the basement to accommodate PVC pipes to the outside- The gaps left around the PVC pipes were only partially caulked on the top of the PVC from the outside but were not caulked at all on the bottom of the PVC. On the inside from the basement you could clearly see daylight through both holes and the void from the inside around both holes was not filled in at all. 6. The pump attached to the humidifier was placed directly on the concrete floor of the basement rather than on something that would raise the pump off the floor to avoid contact with any moisture. The salesman, who was also very courteous and professional, assured me the quality of work performed by his crew would surpass that of previous contractors. This is no different than other contractors especially given the price I paid, which was high. What concerns me the most is that if details like this were overlooked, what else was overlooked that I can't see directly? Given the price I paid, which was on the high end, I expected flawless service. It is attention to detail that produces an exceptional quality product in the end. I suppose only time will tell.

Challenging job well done

We have an older solidly built Kutz home with three custom-sized in-wall air conditioners that needed replaced (2 on the top floor and 1 on the second). Definitely not an easy job!! Joe was kind enough to come out on a Sunday in the rain to measure and then researched to give us the best product at a fair price. Nathan and Chris showed up on right as scheduled to remove the old units and install the new. They encountered challenge after challenge and still managed to get those units in and functioning in one day. Nathan then came back promptly (thank you Angie!) and put the final touches in place and answered all our questions. Nothing but good to say about the DiBiase team. Highly recommended. We will definitely be calling them again next year for the other three.

Great service

Friendly service. Bryan came in and quickly went to work doing a full inspection of my ac system. Any questions I had, he was quick to provide answers if he had them, or point in the right direction for whatever else I needed.

Performed precision a/c tune up on older Carrier r-22 heat pump. Replaced 20x20x1 air filter. Checked all electrical conections and components. Found burnt and pitted contactor on outdoor heatpump, recommended replacing contactor. Checked temperature split at air handler. Tested capacitors inside and out. Found a lot of bacterial growth in the air handler, recommended installing a uv air purifier for better indoor air quality . Checked refrigerant pressures and temperatures at indoor and outdoor units. Called owner of Rita’s to talk to customer about renewing the maintenance plan, he is going to look over the info. Heat pump system is working at time of inspection.

Found Carrier gas furnace with high limit error code soft lockout. Made call for heat from thermostat. Found dirty filter. Replaced filter But observed system had high supply static pressure even after replacing filter. Checked gas pressure. Measured temperature rise. Combustion/draft test: Good (2) 6” flex leads going to second floor are tied to a tee the other side of which is an 8” flex to the return. The 2 6” leads were originally supply leads but presumably made into returns to avoid high return static. These 2 leads being converted to returns is what is causing high supply static. While the system did not shut off on high limit after replacing filter, supply temperature was slightly high and if this problem recurs we will need to provide quote to adjust duct work. I left an additional 16x25x1 filter near furnace. Furnace is operating well at the time of this service.

Found low voltage wiring plug not plugged into terminal block. Found in cool cloud app communication error. Put plug back in and found when furnace inducer tries to run in first stage inducer motor runs for a short period then stops before lightning hot surface igniter . Then furnace tries for 2nd stage and runs just fine. Recommend to customer to replace the circuit board and pressure switches together. Called distributer and ordered parts. Showed homeowner how to reset furnace for now. Found circuit board not starting inducer motor in first stage heating

Oil Boiler tune Up for Dunkirk oil boiler system: Cleaned and inspected flue piping and heat exchanger. Checked piping for design, components and any leaks. Replaced oil filter, replaced nozzle, replaced strainer. Inspected cad cell eye, transformer, primary control, and electrodes. Verified HydroStat operation and settings. Verified thermostat operation. Checked pump pressure and cut off. Measured piping temperature differential and monitored boiler temperature and pressure during heating cycle. Combustion/draft/smoke test: Good Part of oil tank close to valve shows signs of breaking down. When valve was shut oil dropped at a slow rate. Recommend replacing oil tank based on these observations. Boiler is operating well at the time of this maintenance.

2/1/22: No heat Service call: 100KBTU Amana Natural gas communicating furnace. Allowed furnace to attempt trial for ignition/ made call for heat at thermostat. Trial for ignition stopped when gas valve should have opened. While checking for 24V at the gas valve molex plug, found that the molex plug itself was not tight. Board was giving 24V at appropriate time. After securing molex plug, furnace operated as designed. Checked temp rise, checked wiring, made sure all wiring connections were sound, uploaded available CoolCloud updates. Verified that there were no communication errors (system is fully communicating including outdoor AC). Verified flame sense/rectification circuit. Furnace is operating well at the time of this service.

Performed oil boiler cleaning/tune up, cleaned heat exchanger and chimney base. Replaced oil filter pump strainer and nozzle, cleaned and readjusted electrodes. Check oil flow and test transformer ok performed combustion and smoke test, check water pressure and temp, test limit on aqua stat ok, water pressure is 17 psi, customer just replaced circulator pump I can still hear some air in hydronic loop, valves and piping is very old and looks like water has been leaking, all valves will be hard to open and close, both zones are still heating customer is aware of this condition, primary control is the old style would recommend upgrading to the new digital screen version. Boiler is very old overall condition is ok but would highly recommend boiler replacement to prevent any breakdowns.

Arrived and checked smoke when system was running, had a 9 on the scale, checked nozzle and z dimension, found that the previous tech had installed a .85/80°B nozzle, data plate calls for a .65/80°A. Changed nozzle, adjusted primary and secondary air. Checked smoke and combustion and everything is working correctly at this time with 0 smoke and 10.9%CO2.

We removed the old unit and outdoor unit, including the return drop and plenum. We removed the old line set and the strapping for it and then ran a new line set with thermostat wire and strapped it in place. Set new furnace and ac coil in existing location but added a metal return drop with boot and also added a metal supply plenum. We readapted to the gas, electric, flu and intake. Installed new remy halo led in the supply plenum and have it wire to a pressure switch which will only turn on when the blower fan is on, as per manufacturer specs. We also installed 11 dampers to zone off second and first floor feeds, and wired it into a new zone panel. We removed old thermostat and replaced it with an ecobee 5 and programmed it to work on duel fuel. Ran a supply feed line to the second floor room off of the master bedroom with a 8inch supply and register installed on the knee wall. Also ran a new thermostat wire with the flex and ran it farther into the house into the main attic and from

The homeowner was not home when I got here but he left the back door open . When I entered the basement the bypass was laying on the ground next to the indoor unit . I had to order a new 12 inch 90 that broke when it fell and some drive to make induct hangers. After that arrived we Then put drive inside across the ductwork to hold up the bypass then taped every joint . Tested system and system is running good at time of service.
