Show up to an AC tune up and notice he’s finishing the basement. Get to the furnace and see a zone panel and that they added duct and zones to the unit.

I explain to the customer you can’t just add on a zone to the system and expect it to work right. He said “they’ve been doing it a long time. They know what they’re doing”.

Can’t wait until it’s done and AC season hits. They added 1,000 square feet to a 3 ton AC system. Current condo is 1,880 ft sq without the basement. You can’t make this stuff up. Furnace output is 78,000 BTUs if anyone is wondering

And I know some of you are gonna complain about the “tune up”. It’s a cleaning. Clean both coils (if needed). Replace filter, clear drain, clean condensate pump, test capacitor and contactor, clean out the condenser. All that stuff. Test system too if it isn’t too cold (too cold right now 53°).
