Newer high efficiency air conditioners are sealed systems with self-lubricating components so no maintenance or service is required for functional systems.

Older standard efficiency systems (15 years +) are very inefficient systems that leak o-zone depleting refrigerant into the atmosphere. These systems should be replaced instead of “bandaged” to ensure cost efficient, safe and environmentally sound operation.

Very Happy with the Whole Process!!

“Don came over to look at my 20 year old furnace and we both decided that it was a good time to have it replaced as winter was approaching. We went with a Carrier which we previously had and has served us well over the years. Don was able to get me a very generous discount from Carrier as the part that the old furnace needed was heavily backordered. A few days later Ashley came with his partner and had it installed in about 4 hours and they were very professional and very nice people. Very happy with the whole process!!”
