When temp rises outside, cold air stops getting produced inside
by Nancy W
My central ac unit is approximately 5 years old, but has been used actively for 4 years (it was installed in a new condo - we are the first owners). It is model H1R0060S05H. The compressor is on the roof of the condo high rise I live in.
The central air conditioner unit works fine when the outside temperature is under around 85. After that, when the inside temp rises, the fan goes on, but the compressor does not. I have checked on the roof, and can see the fan blades turning, but no hot air is being released as I would expect if the compressor were on. In addition, no cold air is being released inside the apartment.
In time, the temperature rises indoors. Eventually (usually up to 1 hour), the compressor goes on and the apartment cools down to the set temp in about 1/2 hour. By this time, the indoor temp could be 7 or 8 degrees above the setting. This cycle repeats until the outdoor temperature falls.
We have had HVACs service, and they took measurements and said everything was fine. When the problem persisted, they came back, and diagnosed it as a capacitor problem. They replaced the capacitor, and that did not solve the problem.
