Kenna took his time to make sure the noises I was hearing from our new unit were exactly reproduced. Once we got to hear the noises, he reassured me that they were, in fact, normal. Kenna explained that we have a more efficient, much larger heat pump system now that operates at a high psi. That's where the new/weird noises come from. He was professional and thorough. I am so pleased with 72 Degrees, their products, services, and professionals!
