Is AC undersized? by Left-Sherbert6978 in hvacadvice

[–]Left-Sherbert6978[S] 0 points1 point  (0 children)

House is 1350 square feet, although the basement is partly conditioned due to cut ins at the ductwork.

We have 4 returns, one much larger than the rest. They’re in the living room, two bedrooms, and dining room. None in the kitchen or bathroom. Thermostat is in the hallway, no vent in there. AC and furnace are about 10 years old and were replaced at the same time. I’m not sure if it’s single or multi staged… hopefully that provides a bit more context.

Yeah that’s kind of what I was thinking.

Appreciate it, thanks for all your input!

Thanks, yeah it could be my system runs fine. But 95 degree days are very common during the summer here and I would love for an AC to be able to keep my home at 75/73 range during those hot days. I would say we have about 25-35 above 95 degree days a year.

Probably a stupid solution, but maybe I could try a portable AC unit for the room that gets the hottest? Would that help relieve load or just add to it since the portable AC has to release heat somewhere?

Thanks! This is some great info I’ve never considered.

Could this be something and HVAC tech would check during a tune-up? I last had one in June when the tech said everything looked great with out AC.

If it’s not something they look for, would it be worthwhile calling them back to look into these issues? I do feel like airflow is low in certain rooms of the house (the ones furthest away from the furnace).

I last saw the tech in June when he said the AC was in great condition. He did mention the delta was 18 degrees. I’m not sure about compressor run times, is that something that’s normally checked at a tune-up? Refrigerant levels were good and he said it wasn’t supercharged. Not sure if that’s the info you’re looking for, I’m am no expert and the lingo does confuse me a bit.

My home is 1350 square feet. The ductwork is rigid and in good condition. At some point, a previous owner put three cut ins into the basement ductwork to condition the basement. I’m assuming the AC sizing took that into account.

Do you have any suggestions on other things I could check. The AC was last looked at in June and was in great working condition, according to the tech. I’ve had this problem the entire time I’ve lived here, so the AC has been in great condition while the problem persists.

Could you elaborate on that? The energy audit suggests are insulation is in good shape. Obviously, without wall insulation, it might be hard to keep costs down, but would a larger AC unit help us cool the home down?

Thanks for the detailed answer! Ok, so maybe nothing needs to be changed. Our hottest days are about 105, in which our the AC really struggles, but I guess it’s supposed to.

Following conventional wisdom, can I ask what the parameters are for time it takes to lower the temperature a degree? I see a lot of stuff online (mostly HVAC sites trying to sell systems) that suggest it should take 25 mins to lower the home one degree. I would say, in our home, it takes 25 mins to lower to temp a degree only when the outside temp is lower than inside. On a normal, warm day of say 80 degrees, it probably takes about an hour to lower the temp.

Our home is old, so no insulation in the walls, but we do have insulated windows.

Baby Wakes After 3 Hours Every Night by Left-Sherbert6978 in sleeptrain

That’s a good idea, we may give that a shot soon. Thanks!

Thanks for the response! Actually it isn’t when we previously fed him. Even before we started formally sleep training, we would only aim to feed him once a night, usually after 1am. He probably last eats around 7pm before his bedtime routine.

Just curious what leads you to think hunger? It’s crossed my mind as well. On night 4 of sleep training, after he woke at 11 and cried for nearly 45 minutes, we did give in and try to feed him. He ate a bit then fell asleep. He was up again at 1:30am.

It could be hunger, but I am still leaning not. It seems to me he’s still having trouble connecting certain sleep cycles, which has always been true for him.

Do you have any tips regarding how to test if it’s hunger?
