Client called us out today due to no cooling for mini split utilized by three separate apartments. Hooked up refrigerant gauges and found pressure to be 1/3 of what manufacturers recommend. This would indicate a refrigerant leak somewhere on the line set or one of the heads. Client agreed to refrigerant leak search. Found leak on head system in unit four. Office will write up estimate for Fujitsu 7K head and refrigerant. Waived leak search after finding leak in less than 15 minutes and clients past projects with us. Thank you for trusting Thompson with your heating, cooling and plumbing needs.
