This pricing is really atrocious. Remove the existing tankless water heater and put a new one just like it in place. Everything is already plumed. This should take maybe two hours. The quote $6800!!!!!!! WTF!!!!

Excellent Service

Christopher Martinez took numerous photos inside and out of the combination unit located on the roof that he shared with me, including meter readings, and carefully answered all of my questions and explained what each reading indicated when he was finished with the job. He was very meticulous and methodical in checking out the entire system, including the electronic filter and the handler, and also in assuring every part of the unit was thoroughly cleaned. I was very impressed with his knowledge and his friendly and polite manner.

7 y.o System check System is operational upon arrival. Cycled cooling. System is producing a 19 to 20° split. Inspected condenser, secondary motor control failed on fan side, pulling a 4.2 out of 5 µF. Compressor side is close to failing. No hard start kit present. Hooked up refrigerant gauges and found pressures to be in spec. Explained to client this type of system has been notorious for refrigerant leaks. Replaced filter. Client will look to have secondary motor control replaced in off-season maintenance. Thank you for trusting Thompson with your heating and cooling and plumbing needs.

After evaluation, determined garbage disposal to be working and issue was with kitchen drain line. Trent approved estimate to snake drain line, used hand snake to make an attempt at clearing stoppage, at approximately 15 feet, did feel stoppage. Went in further to ensure stoppage was clear and was able to hear a rush of water go down drain. Filled up sink basins and water did drain, disposal still working/running. No leaks from drainage pipes **NO WARRANTY on drain clearing services due to unknown condition of pipes and cannot control what goes down sink.

Failed low voltage fuse, this occurs when there is a low voltage short. Searched for a low voltage short and narrowed it down to the outdoor unit. Tested all portions of the unit that would cause this and nothing was shorted. Outdoor unit is 15 yrs old and the furnace is over 20 system replacement is recommended to avoid any downtime or issues in the future.
