Great Service

Chris has been servicing out heater and air condition for a few years. We bought both units from DiBase when we moved into our home.We could not give anything but positive reviews about Chris and look forward to seeing him. The person that scheduled our appointment was so professional and pleasant. We recommend them whenever we can.

Quick response to heating emergency

I came home from work to a cold house on a January night, determined the heating system wasn't working, called DiBiase, and the dispatcher scheduled a technician to arrive within the hour. He arrived in good time, replaced a failed igniter and stayed long enough to ensure the system was heating the house properly. I put my kids to bed in a warm house that same night.

Excellent service

Chris was remarkably thorough and communicative with lots of information about options open to us. Instead of pressure to take the expensive way, he provided ideas on how to simplify and save. The service itself was excellent.

Furnace was running when I arrived. Looked up code on Lennox gas furnace for 273 and found code to be last recycle due to flame failure. While I was in basement found furnace flames being blown around by high wind gusts down intake pipe , this was probibly what was making the error code happen. Also found flame sensor to be slightly dirty so also cleaned flame sensor. Cycled furnace for a little while any everything kept running , but did notice when hard wind gusts blew flames would move let home owner know all of this. Talked to homeowner about humidifier and she said she was not going to use it at this time. Went outside and found venting system to be half broken off. Talked to homeowner about repairing venting during tune up next week they agreed.

Service call that the Gas Furnace was not operating. Arrived onsite and spoke with Homeowner about issue. The system was blowing Cold Air but was not providing Hot Air. Proceeded to the Furnace to troubleshoot. Blower Motor was running and System was in a 13 Flash Code Lockout indicating that a Limit Switch was open. Tested Safety Switches and found the Primary Limit on the Furnace was open. This Limit automatically resets itself and had failed. Bypassed Limit Switch and put system in operation to determine if their was an underlying issue to the failure of the Main Limit. Performed a Combustion Test on Furnace. Inspected and tested Integrity of Heat Exchanger using the Smoke Test. The Furnace is running at higher than normal Supply Air Temperature. Furnace is rated for a 45-75 Degree Temperature Differential and is running around a 85 Degree Differential with a Supply Temperature around 145 Degrees. The Primary Limit is set to reset at 160 Degrees. Inspected the Indoor Coil which had

When I arrived I found that the inducer moter was full of water and the condensate drain was clogged. Had to remove inducer moter and drain out , also blew out all condensate tubing lots of junk in vents drained out ,also furnace trap was full of gunk blew out as best as I could and cycled furnace for a while to make sure everything was drawing properly again. Home owner had also mentioned having a hot smell coming from gas furnace so examined wiring and checked for desorption in flames when blower came on everything seems to be fine at time of service. Home owner does have an electrostatic filter so may just be burning off dust.

Found that furnace was locked out on a code 7 ignition lock out due to re tries . Had 26.91 volts going to gas valve but not opening. Called johnstone for price and availability, they had valve so ran over and picked up gas valve and replaced. While replacing valve also noticed that wind was rushing down the vent pipes and told homeowner that during these high winds pressure switches can be affected until winds would come down and shut down furnace and would need to try an reset . Also tested for leaks and gas pressures on gas valve I had 8.2 w.c. Coming in and 3.6 w.c. Coming out , furnace back up in operation again.
