What do you guys use for the following?

-Your filter setting

-UV light setting?

-Cycles per hour?

-Deadband setting?

Thanks for your help!

What thermostat are you using? What does the filter recommend? etc. Other than that, I don't allow a compressor to cycle more than every 10 minutes and prefer 2 between heating and cooling stages.

Edit: between heating stages and between cooling stages

The deadband settings determine haw much the temperature must change before the next heating or cooling stage (if you have more that one) comes on. A common setting is 2F.

The cycles per hour is the number of times the compressor is allowed to cycle on and off during any cooling period. Several factors contribute to the cycling. In general, a higher outdoor temperature, a lower indoor thermostat setting, and a less well insulated interior will lead to more cycling. The more the compressor cycles, the greater the strain on the compressor. It's a good idea to not allow it to cycle less than 10 minutes apart which equates to 6 cycles per hour.

Most compressors require time to recover after being turned completely off, usually 3 to 5 minutes. Five minutes is a safe setting.

Sounds like nobody wants to share the filter hour setting. I read 500 hours on the internet.

I don't believe people are reluctant to share. Rather, most people change their HVAC filter(s) based on time elapsed since the last change as opposed to time in use. The same is true, for example, with car oil changes. Oil is usually changed by number of miles driven, not number of hours the engine was running.

There is no doubt, IMO, that time in use is a better measure. A car that idles a lot should have the oil changed more often, an HVAC filter change based on hours in use is more accurate. That's an advantage of the filter timer.

But other factors are involved, such as local air quality, pets, smokers, people with allergies or asthma, people who cook a lot, etc. There is no one size fits all, just a recommended starting place (e.g., 500 hours).

UV filter bulbs are more critical because the bulb will continue to illuminate long after it has lost its effectiveness. But UV filter bulb manufactures usually give the effective life rating in hours and in such cases, the UV time indicator is convenient.
