We came back to ensure all tasks and testing were completed, due to clients having obligations to handle yesterday I reached out to management to setup for us to come back and get the job 100% finalized. We ensured that all modes were working perfectly and that the job will be ready for inspections. With the completion of the install the clients will be able to have ac for this summer season. We look forward to being able to make a difference in our communities

Here in the Danville area performing a furnace, ac, and coil replacement. During the removal the riser ducts for the supply duct that goes upstairs had fell apart in the wall, also the return plenum fell down as well, so before I was able to start doing g the new install, I ensured that all issues were taking care of. We will now be able to finish tomorrow with only a half days of work

Starting off the day with an ac maintenance. This is a Goodman unit around 25 years old. This unit has r-22 refrigerant, a refrigerant that is now obsolete. We did a full cleaning . Looks like no one has cleaned it properly in a long time! So of coarse we made sure it was done properly today! Preventative maintenance are so important! Checking out of Danville ca!

I am in Danville, California to discuss options on replacing a central system

Today we started off with a filter change/ cleaning. We have a filter program designed for clients who have a hard time changing their own filters.Maybe our filter is under the house or in the attic, sometimes filters are hard for clients to reach . Sometimes we just forget all about the filter and need a reminder before it damages our machine. Certified has your back! Checking out of Danville Ca!
