Replaced compressor that was quoted yesterday. Unit did not have a filter line drier so it caused the compressor to fail prematurely. Brazed out old compressor and brazed in new compressor while flowing nitrogen. Added filter line drier. Pressure tested to 250psi and unit held pressure. Vacuumed unit to 480 microns and it held. Started unit up and added refrigerant to match manufacturing specs. System has 15 degrees superheat and 10 degrees subcool. System is cooling properly at this time.

Quote only call. Homeowner received a quote from a previous company to replace compressor but called us instead. Gave homeowner our price and he approved the repair. I checked the condition of the evaporator coil and there are no leaks present at this time. Homeowner is aware of the rusted condition of the evaporator coil but does not want quotes for a new system at this time. I have called Trane supply in Duluth and put the part on a PO.

Dee was so friendly, professional and helpful. I crushed my ankle and am in a wheelchair presently. He offered to bring my trash bins in from the curb & p/u a delivery for me that was left outside. He described what to expect and worked all day. He has almost 19 years plumbing experience, I highly recommend him regarding your plumbing needs.

Due to the visible damage of the service entrance cable from a tree falling on the power line and pulling the service cable off of the house. We can not see what other damages are done to the cable on the interior of the home. The panel that was originally installed with the home needs to be replaced as well due to it being outdated and not having a main shutoff. All items on this estimate are required by the authority having jurisdiction to replace with doing a service replacement per code requirements. We recommend doing a full service replacement. This will replace the damaged cable, install a new meter with a service disconnect outside, a new panel with breakers, smoke and smoke/carbon monoxide alarms, surge protector and updated grounding system.

Arrived to replace leaking evaporator coil. Began by picking up coil from Apex and drove on site. Once on site I began by recovering just under 6lbs of r410a. After refrigerant was recovered I cut out the old coil and the old drier. The old coil was an N coil and the replacement was an A coil. The new coil was taller so I had to make some adjustments to the supply plenum but was able to make it fit. Once we brazed in the new coil and drier while flowing nitrogen I pressure tested the system with 400lbs of nitrogen and let it hold for 10-15 minutes while we checked for leaks. After confirming that the system had no leaks, I hooked up the vacuum and pulled a vacuum down to 320 microns. With the pump and hoses disconnected the system stayed pulled down to 400 microns for 10 minutes before we weighed in factory charge. The system calls code 9lbs and 12oz. We added a few ounces to account for the lineset length. We hooked back up the drains, flue pipe when all other secondary and tertiary

I was called out to Bill’s house for a Homecare maintenance. During the evaluation we discovered there was some growth inside the air handler, the filter was dirty, the flood protection needed updated to our new policy, and the compressor would benefit from a superboost since it runs year round. Today I replaced the air filter and added the wet switch since we installed the upstairs system.

As well as addressing our immediate concern (a “frozen” hot water supply valve), Allen Murphy quickly recognized a secondary issue that was creating low hot water pressure to the rest of the house. He explained the situation clearly and succinctly. I am (again) extremely satisfied with the professionalism, knowledge, and friendliness shown by TE Certified team members in all of my experiences with them!

We needed to replace an old water heater that stopped working and was beginning to leak. We replaced it with a tankless heater and it was a complicated installation for a variety of reasons. Josh did fantastic work with close attention to detail. Everything was precise, including the cleanup when finished, and it works great.
