Found the unit not cooling due to a bad capacitor. Upon investigation, I found that the cap went bad from poor wiring on the contactor. I took video of this. The compressor itself is in good condition, so I believe the compressor was not to blame for the cap going bad. The bare minimum basic repairs to get the system running today.

Client claimed that there was a noise coming out of the furnace every time you take out and put in the filter. It makes a humming noise used to self tapping screws to secure filter rack a little tighter to the furnace to eliminate noise.

I was called out to Mr. David house today because he had two rooms that were not cooling down. These two rooms are located near the front of the house with two big windows. One room is where Mr. David works on his computers and another room is for someone stays. We were currently getting 65° of air and 78 degrees being sucked in, threw the return And hardly any airflow into these rooms we proceeded to do it through evaluation of the entire system, and as we were going into the attic, we heard a hissing noise coming from the unit. We proceeded to checking the evaporator coil by opening the panels. Once we opened up the panels, we found a ongoing leak On one of the distribution tubes. We proceeded to take a video, and to notify Mr. David of his ongoing leak in his evaporator coil. We explained to Mr. David that there is an ongoing leak with his system, due to being low on refrigerant, the system is not working at its full capacity we also showed him the evaporator coil that is rusted and

David and John did an excellent job replacing 12 old 6” can lights with modern LED bulbs; installed 4 new 12” can lights; and installed 4 new remote ceiling fans with LED lights; which improved energy efficiency and reduced the temperature within the rooms. All for a reasonable and fair price. These TE Certified electricians also answered questions on additional electrical upgrades. This company has always sent very knowledgeable and friendly technicians whose work is impeccable, and we highly recommend TE Certified for any electrical, HVAC, plumbing, and generator services. They are awesome!
