AC won't turn on, troubleshooting?

[synapse88]

Its a 15 year old Trane Heat Pump, worked fine until I had the bright idea to install a digital thermostat. Bought the Hunter 44860, turned off the breakers for the HVAC, installed the Hunter, turned the breakers back on and nothing would turn on. Reinstalled the old thermostat and still no AC. I have a service call in with a local HVAC company, but while I'm waiting what can I check?

I know the transformer can get fried in cases like this...how can I check that? I have a nice multimeter and I'm pretty handy with it if need be.

What all can I check while I'm waiting on the professionals to get here? (could be as late as Tuesday...American Home Shield )

Thanks everyone

Not really allowed to offer advice to home owners.
However I wonder if you can command the fan on for the air handler ? There should be an auto and a manual setting.

Could be a couple things. Including some that have nothing to do with changing the thermostat.

While the tech is there.
Buy a good thermostat from him. Hunters makes a great ceiling fan, but crappy thermostats.
They tend not to last.

The only good thing about Hunter thermostats is when they pay me to take them off the wall and buy a real stat from me. Depending on what thermostat you have and I am in no way familiar or care to be with Hunter, there are different configurations depending on what type of system you have. The only advice I will give to you is to READ THE INSTRUCTIONS. I do on thermostats and I do it for a living to make sure I didn't miss anything. As far as waiting til Tuesday, if you pay somebody and avoid that crappy AHS, they will be out before then.

perfect example of why an HVAC contractor should be hired when making modifications to your HVAC system

you probably burned up some parts, you should stop the guess work to keep your damages to a minimum!

I assume when you burn the bacon for breakfast, you call the local restaurant and ask them how to properly cook the bacon? Or the eggs? Or the fish? C'mon. When you buy any product that is normally installed by a professional, it's called Do It Yourself. Once you require the expertise of the pro, it's no longer DIY. So, then you must pay the full price of both the part PLUS the installation. Net savings, zero. Cost to complete the project, far more than if you had called the pro in the first place. MORAL: If you're not 100% sure you can DIY, then don't even attempt it. Dental drills are cheap. Do you go to a dentist or repair your own cavities yourself?

What info do you need?

You don't go to my job with what? You're working here?


I really don't understand your guys refusal to offer even the slightest idea of what might be wrong. You all are telling me to call a tech, but I've already done so.

Even if you can't give me troubleshooting advice you can at least give me some possibilities so I know what to expect when the tech does get here.

[beenthere]

You should expect a curtious service tech.
And a bill for some parts, and to pay the tech COD if its because youo installed that thermostat, because home warranty companies don't cover this kind of repair.

If its unrelated to the thermostat. The tech will tell you.

We can't see or check your system from hear.
