I am going to build a new house

A week ago, when the weather was quite even and not too sizzling or too cold, I woke up 1 day and discovered that the house was measuring about 88 degrees. I went to the thermostat and pushed it lower, in the hopes that would make the a/c kick on as it is supposed to. Unfortunately, there was no luck. I called in the local heating and cooling company to see if they could come out for an Heating and A/C repair visit and determine what was going on with the a/c. They Heating and A/C company was quite professional and unquestionably easy to deal with. The a/c repair specialist called while enroute to make sure the two of us knew he was on his way. He was pleasant when he arrived and set about to do the a/c inspection straightaway. He was diligent while using his tools to open up the outdoor a/c equipment and was careful not to drag dirt or grease when he came into the house. After inspecting the air vents, the ducts, and the compressor, he gave us the exhausting news. The Heating and A/C system repairs would be extensive. He proposed that it might be a good method to update the Heating and A/C rather than repair it, since the repair costs would be high. The two of us decided the two of us would need some time to believe it over, and since the weather was so perfect, the two of us did not hurry ourselves along. Now, though, it is getting quite cold at night, and I am in need of a gas furnace than works well. The time has come to make a decision. Should the two of us repair or update the Heating and A/C system?
