New AC's Cooling Much better than the old ones

Question

My original AC units 2, 13500 and 15000 btu's were 10 years old.
I replaced them with 2 15000 btu Penguin II High Capacity Air Conditioner's and I added a 3rd unit of the same type.

I stay out in the Palm Springs area in the summer where it gets HOT HOT ! With my old units once it got to 100 outside you felt it inside. 105 and over it was time to bug out.

Now with 2 of the new units going it is cold at 100 degrees, and at 105 (so far 1 day) with all 3 units going full blast it was 71 inside the RV.

These new units are soooo much better than my old ones.

Thank you for sharing.  I have often wondered if there was much gain to replacing my aging 13.5 BTU with a newer unit.  Now I know.

The new R-410 units will run in higher temps much better. They are also typically more energy efficient!

Did you get a heat pump model? That would be nice if you full time, and are in campgrounds in the winter.

Also if the older units where not washed on a regular basis, they can lose about 5% - 10% of their ability to exchange the heat due to soil on the coils. Wash the outside coil with a garden hose once a year, and it will return to peak performance!

And it is possible that your older units where slightly low on freon. This can drop their rated capacity by 10% or more.

Good luck with the new units!

Fred.

When one of my 13,500 units went out due to a manufacturing defect I upgraded to 15000 as well.. Amazing thing is I did NOT increase power usage.. They are both 13.5 amps. running,, measured and verified no less.
