Our heat pump was 14 years old and for being three blocks from the ocean and 100 feet from the bay, it didn't owe us much. I am an engineer and know enough about HVAC equipment to ask the proper questions. Artic answered them all thoroughly and professionally. I shopped around for a more efficient unit and found spec item for spec item you can pay much more for a name. Artics brand is lesser known but stands tall against the common names like carrier. Artic has a ten year parts and labor Guarantee and the compressor has a lifetime guarantee. The crew was on time and set up for covid. The condensing ubit and AHU went in quickly. We bad a ding in a low ceiling on ourstairs but outside of that we were 100% satisfied. The unit has only been running for 48 hours but so car so good. We got the salt shield for extra life. .
