"Is there a start delay device that detects outages and slowly reboots?"

Yes,readly available and simple to install but not a diy project.

Some (electronic) thermostats have a restart delay that comes into play both for power outages and normal (too fast) cycling. Some system control boards also have a built-in delay.

I'm confused dadoes,I figure op might be to. Are you suggesting he upgrade t-stat and/or control board to solve his short cycle problem?

Are there any Professionals lefts? Worked 22yrs. in Construction. 98% of the labor doing the work have no license. They call the guy sitting at the office.

I asked a simple question. Regarding available products. Not installation advice. What I am trying to avoid is calling a so called pro and being charged Professional prices for a guy to say hold on need to call about this. If I know about a product, research it. Than I'm less likely to be overcharged by a licensed individual.

Easiest way to tell if you have a honest Hvac professional. 2 ton residential split system. Get a quote for replacing the outside capacitor. Any thing over $125.00 they are a scammer. $6 part.

If they ever want to top your system off. Wrong, does your fridge ever need topped of? How about car? No, these are sealed systems. If they need topped than there is a leak.

Educate all, hide nothing, help each other. There are better ways! Good Luck!

There's this story about a nuclear plant facing imminent catastrophe. The plant a week or two earlier thought it wise to get rid of the high cost nuclear engineers that run the plant as they said 'what do these guys really do?' All we ever see them do is sit around chat and drink coffee all day.

Now however, the nuclear plant is about to blow it's top, which will spew nuclear debris for miles. They get on the phone and call the 'so called' nuclear guy that sat around drinking coffee all day chatting with other workers in the plant. You know a cost cutting move.

The guy tells them he will bill them for his services as he 'no longer works there'. They say yes, 'whatever you want'... please HURRY!

The nuclear guy is there in 5 minutes studies the panels and instrumentation walks over to a series of switches and knobs and flips a single switch.

The nuclear melt down doesn't occur everything goes back into normal operational mode.

The next week the plant gets the bill for $250,001.00 They are astounded at the bill and they ask the nuclear scientist to break down the bill as they are having trouble determining what the 'FAIR' cost is for flipping a 'single switch'.

The nuclear scientist says sure I can break down the bill for you. To flip the single switch cost $1. To know 'WHICH' switch to flip cost $250,000.00

There's a lesson in there somewhere.

Sounds like it might be a loose wire ‘somewhere’, a loose connection or breaker in your electrical panel load center, possibly in improperly charged system, possibly as you suggested, a defective start/run capacitor, etc.

Best to have it service by an accredited, experienced professional that knows what they’re doing.

I would also install at the main panel & electrical entrance to the house, a ‘Whole House Surge Protector’ that protects everything 110v & 220v as cheap spike insurance.

Hum no engineers. What about security? Went on vacation last year to place called Turtle beach in Florida. Nuclear power plant on the beach. As we drive over the spill way and taste, smell, feel the battery acid. To notice that 10 feet from the road is a wide open door to the Plant! But hey it's engineers said we need nuclear power! But the bunkers that store the toxic ooze are locked securely for a 1000 years. Shame we can't figure out how to charge the consumer for free electric! Than everybody would have solar!
