Seattle Heating and Cooling's team installed our new heat pump, and we've been impressed by the efficiency and comfort of our home since. Their expertise was evident from start to finish.
VLAD, K. 
Our estimate and actual mini split installation visits with Seattle HVAC went smoothly. The office representative was a pleasure to talk with while I explained everything. Installers were friendly and polite. Worked fast and and left the house clean. Was some language barrier, but Serge came right after the installation and explained everything and provided instructions on how to use the new system. Overall, very satisfied with the quality of service.
MOHAMMED, A.
Want to share my experience with Seattle Heating and Cooling. Very impressed with the work that they did. Everyone has been great to work with and made the process of getting 5-zone ductless mini split installation easy. Arrived on time and worked until the job was complete which was after 7PM. Highly recommend.
MARTIN, G. 
Serge was friendly and easy to talk to. After we decided to replace our heat pump he thoroughly discussed all future replacements that would be necessary. 5-star!
