My system is (rheem) is close to 40 years old....still working like a champ

Ever since an HVAC tech replaced a capacitor on my exterior unit, my thermostat makes 2 clicks when I turn it from off to heat or cool. There are, also, 5 minute delays when switching from heat to cool and immediately back to heat and vice versa. Unit doesn't stop immediately, if I turn it off after turning the temp up or down in quick succession...maybe a few seconds delay. The thermostat, also, behaves differently in that it now runs beyond the desired temperature on the display, but refrigerator thermometers balanced on top of the thermostat and one on the table always read the desired temperature indicated on the display when it finishes. Trying to figure out why when I turn the heat from 69 to 70, the thermostat will reach 70, but continue on until the refrigerator thermometers read 70. I replaced the thermostat with a new one, identical brand and model. These are non-programmable thermostats, but I know another HVAC tech had to program something into it by holding certain buttons down to get 'emergency heat' mode as an option. It can't be my thermostat since this happens with both the old one and the new one. Some KZbinrs say there is supposed to be a delay before the unit responds to protect the compressor, but I found one who said there was a short or blown fuse on the exterior unit. Regardless, changing temp or modes always triggered an immediate response, no delays of any kind and the unit stopped at the desired temp I'd selected. Any clue? I just know neither thermostat behaves as it did before that capacitor was changed. The system is 6 years old, forced air electric heat pump, but only 4 years of normal use because the house sat for a while, so I kept the house very chilly in the winter (50 degrees) and warm in the summer (probably 80-85 degrees).

I bought a baby dehumidifier (60w) and it made a huge difference, dropping the humidity from 62% to 52% in most of the house (and 63% to 58% in the back bedroom). As far as warm vs cold, I have found that within 2 weeks I adapt to 78 degrees. 30% humidity causes my nose to bleed so that's not for me.

72?! Holy smokes, I thought I was being a rich boy keeping it at 78! 72 is downright cold.

I paid 15 grand for heat pumps. If it's hot outside I want to have icicles forming on my moustache inside. If it's cold outside I better be sweating in a tank top inside.

We got a new 2.5 ton Frigidaire heat pump at the end of July when our old system died. The old system struggled (read incapable) of reaching comfortable temps in the summer. Let's compare bills, our July bill in which we spent 22 days out of the house (set to 80*) from vacation or waiting for a new heat pump install was $138. Got the new unit installed and ran it to comfort for 1 month straight, $148. $10 difference in power bill for 22 additional days of comfort. Tstat programmed to go up to 76 when we're not home during the day, 69 when the sun goes down. Replace your old unit yesterday.

Thank you. Very helpful!

Thank you! My one inch filter was in my air conditioner for a YEAR. And I was wondering why I had allergies 😅

Thanks for the informative video.
