How to check your own Home & HVAC air conditioning system:

There is also a link on the page, linked below, to an Iowa Public Radio program audio archive on "Home Energy & HVAC Rating."

You could, if you're willing to, cut your home energy usage & costs in half.

In over a 1,000 HVAC systems, new & old systems, checked they were only getting 55 to 60% of their mfg'ers rated performance. - udarrell

I just now came back to see some responses here.
Hey, Coolmen CJ, congratulations on being NCI Certified.

No it is not spam; I nor no one else makes a penny from the information I provide on my Web sites.

However, if you are a good Tech, you will get a lot more work, because when folks get interested in how their HVAC system is performing & in knowing how to reduce energy use, they will call a contractor for Tech help. I think he is getting a little too hi tech. for the home owner to do all this checking.

I don't actually disagree with you Paul.

The Tech needs all the air testing instruments; the folks running my simple test only need a thermometer & either a humidity gage or do a wet bull temp check.

They can respond on twitter or on a forum, or e-mail me, & I'll go much further with that seemingly insignificant information.

Just using that little info data; I can tell them an amazing amount of performance & trouble shooting information, concerning their system's performance.

If they provide supply air & rerurn air wet bulb, I can closely ballpark with psychrometric software the BTUH that their system is delivering within those operating conditions.

Every Tech could do that, especially if they had worked in HVAC/R since before the mid-1970's.

The mfg'ers ought to provide the condenser splits so I wouldn't have to do extra figuring to get the condenser temp split at differing load conditions.

Challenge me with actual test data & I'll show what we can come up with I need to know the "SEER Rating of the condenser."

Typing with eraser ends of pencils, cause my hands are messed-up is difficult so I'll quit, for now. - udarrell
