Should HI's perform SH and SC
So, lets have some fun. What do you folks think about training home inspectors to determine the SH and SC of systems during the course of an inspection. The key would, of course, be the training or should the current standard of two temperatures (return and supply) and a general visual be enough.
If a home inspector wished to increase his knowledge by becoming EPA certified, taking formal training in HVAC theory and application, and then apply that knowledge to his home inspections, I wouldn't have any heartburn with that. He might find he'd have to carry an HVAC contracting license along with whatever he might need for inspecting homes, depending on where he operates. Many home inspectors might not see the value for the time invested...they'll just stick with doing a sensible temperature split across the vents and call it good.
Personally I think most home inspectors should defer HVAC performance inspections to HVAC contractors who are skilled in determining actual HVAC performance. Admittedly, finding a contractor with that capability is not easy. What I think should happen more often in these days of higher energy costs is that an energy audit of the home be included in the transaction, so the prospective buyer has an idea going in what he may up against as far as costs to keep the house comfortable. Integral to that audit should be actual evaluation of the HVAC performance, along with noting any potential problems with the system. The main stickler would be who would pay for such a thing...seller or buyer?

could you imagine how stupid they would try and make the a/c guy or gal look if they went any farther?

A Good Thread toward Thinking about Energy Conservation
Great posts to foster some thinking about what might be helpful toward the needed "Conservation of Energy."
I am for the energy audit in the form of a heat-gain heat-loss calc, that would be made part of the home's records.
Inspectors could also be equipped to do a Blower Door infiltration test, & a Duct-Blaster test. Seems like I recall that CA does that.
Since far too few service techs are doing it, wouldn't it be great if the inspectors did a duct system ESP check & an airflow velocity & CFM report, with a permanent record for clueless so-called techs, ha!
If America is going to be serious Energy conservation, we need a lot of tech service work to be mandatory.
They rule mandated the end of the mfg'er of 12-SEER units that most could be made to achieve 13-SEER Ratings! Those 12-evaporators would fit where the new 13's won't fit.

NO. They should require a full inspection of both the furnace and the a/c system. By a reputable company. Job security for us and peace of mind for the homeowner and the insurance company. I would bet insurance rates would go down.

Most HIs are Shlameels........ lol
Would probably cause more confusuion then what it would be worth.
Too many variables can cause the SH, and SC to be off, for them to say what is wrong. If anything. So still need a rech to come out and check the system. So it wouldn't benefit anyone.
Let alone if a schrader goes bad while disconnecting. They would now have to repair the damage they did.
And recharge the system for free.
my favorite on home inspectors is when they inspect a home ac the home is 90° and high humidity and they write up 14° evap coil temp difference should be between 15 and 20 this could indicate a problem. i dont think home inspectors should even touch the ac home buyers should have a hvac co inspect they systems before purchase
Last I knew WI required a home energy audit on all homes before they can be transfered for use as a rental property. The home has to be brought up to energy code standards before the purchase can be finalized.
Why this isn't the case for every other residence being sold I have nooooooooo clue.
Use the biggest hammer you like, pounding a square peg into a round hole does not equal a proper fit.
i say call the professional. I get tired of going into homes where the HI says everythings ok on a 30 yr old furnace/ac you get out there to fix or replace and they tell you I didnt know its that much and by the way I have a home warranty.
Shlameels I'm tellin ya! lol
I am not even sure if home inspectors should be performing home inspections, much less trying to do hvac work.
I believe most HI's are there to determine whether the home is structurally safe or not. If you as a seller sell your house as is, doesn't that mean as is.
I have been to many homes that were sold to new owners with AC systems that were working but 30 yo and falling apart. AC guy was there before the closing, gave a little go go juice and system is working, contract signed and every one is on there way.
What if you were selling your house and the HI said you had a deficient system and had to layout 5 to 10 grand before the new owner moved in or the plumbing wasn't up to par.
Maybe I just have a bad attitude about the HI process.
If HI's looked real close they would find a lot of faults with a lot of houses and the whole process would slow down or stop. Hey thats just my opinion
