The installer told me that the new complicated multi speed high seer units rarely actually achieve the touted seer number. I'm ln an ac installer group on Facebook. Several pros on there have said that the new complicated units are a lot more prone to break downs and that parts and repairs are more expensive.

Of course the guys on Facebook are going to say that lol. You have HVAC techs very comfortable fixing very basic systems. Anything new and more complex is going to be rejected because it’s change. New is no good, right? All I can say is I’m saving about $50 per
Month on electric and the temperature and humidity are rock solid. My home is significantly more comfortable with the variable speed system. With 10 years parts and labor included I don’t worry about repairs or the cost. I can say although the variable speed systems used to be more prone to repairs, the newer systems are more reliable than the old single stage systems now and should last longer with proper maintenance. Fortunately, there are many knowledgeable and hard working HVAC technicians out there who are not on Facebook who are embracing this new technology, which is really not that new, especially since it’s the same technology used in the mini split systems everyone is installing, and will support us into the future. I believe at some point there will be a minimum efficiency rating that all these new systems will need to achieve and the old basic single stage technology will not be able to meet and thus not be available any more. I guess we will see.
