Syed did a wonderful job of replacing our nest thermostat with ecobee. He was on-time, courteous and friendly. He tested the HVAC before and after the change and went extra mile in making sure that everything worked properly and looked good. Thank you so much.

Syed from Mast was excellent. He came on time, knew exactly what to do and went beyond his mandate to do extra work to make sure that my thermostat was working. Highly recommended.

Syed was timely and professional. He not only replaced my new thermostat but provided some very useful maintenance tips to me.

Great, great work from Syed from Mast Service! He fit me in earlier then expected, texted me updates about his arrival time. He installed my new Nest thermostat and stayed to help me through the set up process. Which was more difficult than I anticipated! I have hired Syed before and I will definitely hire him again!

Syed’s responsiveness and work was outstanding! He quickly evaluated the problem with my air conditioning unit, fixed the issue and expertly programed my new smart thermostat! He even waited until the unit was 100% operational after programming and recalibration. I would definitely recommend Mast Services!
