Concerned over gas leak.

Luis was our technician. Because he has done much of the maintenance on our units after install, he is very familiar with our system. Luis is friendly, efficient and takes the time to listen to all of your questions and explain everything in detail. I've dealt with a number of different HVAC professionals as we used to have a home warranty company. Luis and the other DiBiase techs are significantly better than any of the other HVAC company's that serviced our older HVAC system.

Fall Maintenance

Luis was the technician who serviced our Central Air in the spring, and serviced the furnace for the fall as well. Luis was prompt in his appointment window, friendly and answered all of the additional questions I had. Everyone from DiBiase has been very professional. Luis was great with offering little tips on what I can do as general maintenance in order to keep the unit running well into the future.

Emergengy Call

There was concern I smelled gas coming from an area right by my water heater. I called DIBIASE at about 10:30 AM thinking I would have a technician out the following day. The scheduler recognized the urgency of the situation and had a tech out the same day at 5:30 PM. The tech had been to our house before so it was nice to see a friendly face. He was able to diagnose the issue quickly and completed the repair quickly as well. The repair was completed in about an hour. As always, The tech was very friendly, personable and answered all my questions.

Great Service, Personal and Thorough

This rating is based on the follow-up inspection as the unit was installed at the beginning of April. The unit has been running as expected without issues. I mentioned an area or two where I felt the unit was not quite proficient; however the technician went into the control settings and made and adjustment that has resolved the issue, and the unit has been working fine ever since. The technicians were the ones who installed the unit, and were great to speak with for both installation and follow-up. They were both personable and answered all of the questions I had; in addition, they allowed me to ask specific follow-up questions in order to get a better understanding of how the unit works and certain maintenance items. I have dealt with a handful of HVAC contractors in the area for both home warranty work, and when pricing out replacement units. DIBIASE was by far the most professional, prompt, and attentive to the needs of our situation.

When I arrived found that on the 2” black iron fill the 2” black iron union had some oil leak during filling the tank. Took apart the union and added some pipe dope to threads . This should help fill any gaps in the threads at union.

Turned on Nest thermostat and furnace fired right up and everything came on. Went outside and checked vents for any debris, no visible debris. Checked drain tubing inside and pressure switch tubing all open. Did find weak blower capacitor. And also heat exchanger is getting rusty. Recommend to start thinking about replacement. Homeowner said he is going to hold off at this point on any repairs and see how it runs from this point on. Re- started furnace and could not get it to re create issue.

Found outdoor heat pump not running. Switched thermostat to only kick on heat pump. Found r-22 pressures were 284/-22 , problem with outdoor expansion valve. Also don’t know if refrigerant levels are ok beacause of bad txv. Recommend replacing both heat pump and oil furnace. Recommend replacing the oil furnace due age of system. Homeowner is contacting his warranty company and they said they might need to get there own company out to verify.
