So, now I know why AC guys make bank

Just finished installing a complete central ac/heating system in my guest house. Maybe if I was younger, it would of been a little easy. I did this with the help of a friend that is a Hvac pro.

Total cost was $3700. Rudd seer 16, 2.5 ton system.

First, installing a air return. Of course one will be cutting a ceiling rafter and then boxing that area in.



Then build a decking for the air handler, put the air handler up in the attic and then start building your return duct.



Had used trusses to build the roof which I had to cut some braces out and then add more.

Of course for real good register boxes, one has to add the correct size starter collars. And yes, there is a special rubber glue to seal up everything that takes 20 hours to dry.



Ended up having 8 drops.

Installing them and flex duct in the ceiling. Of course more of that rubber sealer. Then you have flex ducts everywhere and holes in your ceiling.





Then it is time to build your discharge duct. Of course installing starter collars there to with more sealer.



Install that and then install all flex ducts.







Then one has to run the set lines, power supply for the blower and power supply for the heater(electrical one). Also run power to the outside unit. All three have their own disconnects.

Then safety float switches, two. Run wiring for the T stat too.



Then a level spot for the condenser unit outside.



Yep, a lot of work in a hot area that took me 8 days.


Would I do it again? Not in this life time. Over all, by doing all the hard stuff, that saved me about 2K. I had two other bids that were in the 8K+. For that crap. Besides, I have more time then money.
