This quote is only for complete mechanical replacement of the fan coil units. This quote assumes that the service valves for both the hot water and chilled water work for each unit.

Install lav sink
Estimate for construction and actuator replacement.
Check dishwasher for leak
I started off cleaning the outdoor units coil with water and coil cleaner. I checked the electrical connections and the capacitor and everything looked good. I went inside and I replaced the air filter with a 20 x 25 x 5 air bear filter. I brushed and flushed the trap with cleaner. I turned off the bypass humidifier. I checked the electrical connections and they looked good. Lastly, I ran the AC unit and everything was operating as it should.
Mark and his entire team do a wonderful job. Show up on time and treat your home with respect. Recommend them without reservations.
Replaced kitchen basket strainer
System was low on charge. I added about 1 pound of R 22 refrigerant. At the end, I was getting a 20° temp split with 43° supply air.
GSMS always goes above and beyond. I have a broken elbow and Mark even helped carrying my vacuum cleaner up stairs for me so I could vacuum whilst he was here!
Check plumbing everything was fine
I started off with cleaning the indoor coil with Dawn soap and water. I brushed and flushed the condensate trap with cleaner. I checked electrical connections and everything looked good. I went outside and I washed the outdoor units coil with water and coil cleaner. I checked the capacitor and that was in spec. Electrical connection looked good as well. The client replaces there own filters. Lastly, I ran the unit in heating mode and the pressures looked good.

Great work—explained work well.
Qwentin did a great job! He was very thorough in cleaning my AC unit (which hadn’t been done in years) and did it with a smile on his face! Very personable as well, I enjoyed talking to him and he explained everything that he was doing. Getting to my AC unit was not easy but he loved the challenge. 🙂
Excellent service as Ive always had from GSMS. I appreciate Jack's quick response and fix on a beautiful Friday spring afternoon!
