The technician was very professional and did a good job with troubleshooting and following up. He cleaned up the working space nicely and wore coverings over his shoes as not to track in stuff.

TE certified will Cut out and replace a 3” x 4” closet 90 going through the foundation of the home and hand dig 3 to 4 feet outside using hydraulic cement and roofing tar as a correct seal around the penetration. The work performed by TE certified would come with a lifetime workmanship warranty. Installation: We repiped the old sewer penetration. The existing pipe was damaged due to foundation settling. We cut out and removed the pipe that was damaged and replaced with new PVC. Tied new PVC into existing plumbing system, then we sealed the outside and inside of the penetration. Tested everything thoroughly ensuring no leaks and proper drainage. Backfilled our excavation site. Then we cleaned up work areas.

Bonus room heat pump not working and blowing cold air. Found dual capacitor bad (reading 35 out of a 40 microfarad) and compressor locked. Replaced capacitor and system works. Inspected air handler and heat pump. Air handler covered by biological growth, blower wheel dirty, low on Freon, and outdated dampers. System is 17 years old and air quality is compromised in the house. Also, possible leaking in the system (couldn’t find any leak in the evaporator coil). Due to the be and conditions of the system, the best option would be to upgrade the system, with 10 years warranty and update the zoning , as well. Set a lead to quote upgrading the heat pump system, for Thursday 02/05 after 3 pm. We should credit back 277,00 if customer upgrade the system.

Upon arrival customer stated that upstairs outdoor system was making noises and showed me a video of what system was doing. After inspection of upstairs system found unit had a failed condenser fan motor, along with failed fan motor the compressor is make a loud clunking noise, only heat strips are working to keep upstairs warm. Ad used customer due to system being obsolete, and age of equipment recommended updating system, customer approved to speak with install supervisor about updating system. Customer also advised me of older system that control basement and porch, I inspected system while on site and found that the porch area thermostat was set to cool and basement was set to heat, the porch thermostat could not be changed out of setting, when I turned off the basement, the porch thermostat would automatically keep bringing on the ac unit even if the temperature was raised, there was no air flow coming from vents due to this zone dampers not opening. Advised customer of issue with

Client reached out in regards to a high water bill. After shutting water off to the home from the valve in the crawlspace. I verified the leak was coming from inside (no leaks in the yard at this time) There are 2 toilets in the home. Both toilet fill valves were failing to shut off. Replaced the failed fill valves on the toilets in the home. I recommended replacing the toilets on age alone but my client wanted to wait for now. Customer had concerns about a laundry drain not draining properly. A portion of this line had been replaced recently. I speculate it’s cast iron related. given the amount of cast iron in the home. We should explore some options as far as removing all cast iron. Sewer supervisor visit scheduled One of the toilets (which is rarely ever used) is leaking from the base, I left some options to fix this, this will also be addressed in the sewer supervisor’s visit due to it being on a lead riser above cast iron.

No heat on the main level system. Wasn’t getting 120 volts from the board. I unwired board and heat works. Circuit board has intermittent issues and should be replaced, with the pressure switch, as well. Also, heat exchanger is very rusted with some hot spots and blower wheel very dirty. No wet switch or any type of water protection installed, in case of drain line, or condensate pump fails. Furnace is 23 years old and it’s on its last legs. Highly recommend to upgrade the furnace, and bring safety, comfort and efficiency back to the house. Sent estimates for the potential repairs (not recommend). Set. Lead to quote upgrading for Monday morning. Also, signed up customer for home care maintenance for both systems in the house.

Upon arrival customer stated that heat stopped working yesterday, stated that she has been having remodeling work done in basement and that filter was very dirty when they changed it and noticed system was in a lockout. Found system still in a lockout and had to reset power to system in order for unit to work again. Restarted system and everything came on. Checked over all operations of system and everything was working with no issues, all zone dampers were opening properly and unit is heating. Unit does need a Uv light sent estimate to customer.

Came for no heat. Call. When arrive to costumer house system had power but it was cycling on and off until shuts down. When testing system found that filter and evap coil were clogged for lack of maintenance and there was also biological growth inside the system spreading, causing poor air flow and system to over and finally shutdown. Proceed to do a complete maintenance, chemically clean evap coil. Added new transformer and UV germicidal light to avoid bio growth to come back and spreading. Costumer also signed up for monthly membership, to keep up with hvac maintenance to avoid any further issues. System is now up and running. Thank you for choosing TE Certified!

Upon are customer stated that heating system was not working properly and turning on and off. After input of 27 year old system found that system is over heating due to inducer draft motor and single wall flue pipe. Blower wheel is very dirty. Gave customer estimate on repairs for system do not recommend due to age and condition of system. There can still be more issues even with repairs being made and there is no warranty on repairs. Do recommend speaking with our install supervisor about updating system, customer is interested in getting a quote for a full system replacement and also needs adjustments for system due to bathroom being built in the area. Customer approved to speak with install supervisor before making any repairs to system.

Client had a lavatory sink in the master bath that was leaking at the drain tailpiece, this leak has been going on for a while and they just noticed some staining coming from the ceiling underneath. Cleaned up tubular connections and ran water for 10 minutes to verify the leak was gone. My client mentioned another stain coming from the attic. There is no plumbing or HVAC condensate drain in this area. There was a bathroom vent that used single wall metal venting. I reached out to an HVAC tech, who mentioned it was highly unlikely that condensation from this vent would be enough to leave a stain in the drywall. I didn’t see any stains or leaks from the 1 year old roof. I would consult an attic specialist / leak search to look further into this matter. It’s certainly not plumbing related. Water heater is from 2021, water pressure is 45 PSI Reached out to property medics to schedule a water damage visit
