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.

Service call that there was an intermittent gas smell coming from either the Furnace or Water Heater. After speaking with Homeowner upon arrival, used Leak Bubble on the Gas Line for the Water Heater and the Furnace. Found a small leak at one of the Nipple Fittings for the Water Heater. Disassembled the section of Gas Line. Cleaned the Fittings and reassembled with new Pipe Sealant. Turned Gas on to the Water Heater and retested the Gas Line to ensure there were no leaks. Relit the pilot and turned the Thermostat Control up to Hot.

Performed Precision Air Conditioning Tune Up on American Standard System. Checked 24x24x1 Air Filter. Filter was recently changed by Homeowner and in good condition. Found the Blower Motor Capacitor was testing below rating. Also found Double Pole Contactor was worn and pitted. Contactor was making a buzzing noise which indicates that the coil is becoming weak. Spoke with Homeowner about recommended Repairs. Provided estimate for repairs which were deferred at this time. Measured Refrigerant Charge on system. System is operating but due to age of system, 16 Years, would recommend to begin planning/saving for replacement of the Gas Furnace/AC system.
