I've seen one blow up like that. Never was able to figure out why. It could have been a defect or something caused by dropping or bouncing around in the back of a truck.

Why the dirt in the blower wheel?

Filter not attached preperly? Blower compartment penetrations? Animals dug hole in return duct between filter grill and blower? Unsealed duct work? Failed...

For hot weather I prefer the KEEN Atlanta. Nice light steel toe shoe. They fit me better than any other shoe and have been a sheer delight to wear. ...

I've bled the high side liquid line into my recovery tank a time or three. The operational compressor will blow it into the recovery tank for you a lot faster than a recovery machine will. You're...

I'm guessing a Hole in the burner mesh. If this is the one I'm
thinking about, the burner
er is flat on the end of the heat exchanger, fed by the combustion fan. There is mesh across it that...

A compressor is just a pump. I've changed a few from recip to scroll. Did one last Wednesday, it worked fine. In my case the original was no longer manufactured. Like others posted, same to same is...

Show up for work ahead of time.

When I did home warranty work, Home warranty companies didn't authorize a leak check until the second incident.

Some Rheem/RUUD coils have a screen just before the TXV. It's contained in a widened piece of copper that looks like a bullet drier or a check valve. You may have crud in that screen or if you...

You may still get a break. Download and print the bulletin and talk to your local dealer. Have him talk with the distributor.

A fan coil and an air handler are two different terms that describe the same thing.
A box with a coil and a blower in it.

Not needed in most installations. Sometimes there will be a resonance with something in the structure and you'll get noise unless you have the isolators. Most are put in to eliminate possible noise...

High limit switches are typically mounted in the actual heat exchanger area.

Aux limit switches are like limit switches, Most are of a different design than the high limit switch. Many aux limit...

A single heating data point like supply air temperature doesn't tell you much.

A 20 degree temp rise across a heat pump indoor coil during heating is good.

Texas has a state license for the contractor. An EPA refrigerant certificate is required for the technician, An HVAC tecnician pays $20 to register with the state and gets a nice plastic card. The...

Safety:
Turn off the power to the unit before you touch a belt or blower motor. Motors will start in an instant and the pulley/belt will amputate fingers faster than you can twitch.

Just got my colonoscopy today.
2 5mm polyp snipped. Everything looked good.

Was running a little behind getting it at 53 years. I asked if I could schedule another one to get caught...

Did you replace it with the correct pressure switch? Some detect positive pressure, others detect negative pressure. Some general purpose switches can detect both, are adjustable and be...

Twice. Replaced both with a 5-2-1 start ki.

Adjustable straps. Some states have Department of Transportation requirements for securing loads. Make sure your method complies or you may get a ticket, or possibly kill someone.

All methods...

Post deleted, Mr Bill has good advice.

I'm assuming that you're not a tech, most suppliers can have new compressors shipped in a few days.

You're rolling the dice. Many people never have a problem with the bristol two stage...

The tee vent leg needs to extend higher than the top of the leak detector switch. This will allow the water to backup and activate the switch instead of coming out of the vent.

I'd check the insulation in the coil box. I've had two different systems installed horizonally that had insulation fall down and cover the top half of the coil. I used some pipe strap and screws to...

It could also be a failed capacitor (some compressors will run with a bad cap, they just use more power)
The outdoor coils could be filthy.
I'd have someone check the heat strips as previously ...

It's hard to tell what the issue is until you do a visual inspection and do some testing. That's why long distance diagnosis is not very productive. They all look fine from my house.

The Supco is not as robust as the OEM or a 5-2-1 start kit. I would not recomment a Supco in this application.

Most sytems can be retrofitted to different defrost control boards. Retrofits are harder and take more time depending on specifics of your system.

It would help to find an experienced ( + 8...

Shepherds crook here too. Use it several times per week.

Put it in test mode and check delta t. You have access to the coils to tell if they are clean. Clean them if dirty. They have sensors out the wazoo to tell you when something breaks. Have codes to...

I don't know your experience or knowledge level. How high is the head pressure and the type of refrigerant? What would normal pressures be at your ambient temperature?

The faster the repair gets made, the better it is for you. Should have had a guy come out and fix it that day. Any delay seems like stalling tactics. Your customer is just watching out for their...

Technical support said to change the ribbon cable. I'd do as they suggest.

As far as I know the Infinity control already has the dual fuel stuff programmed into it, lots of options. No need for a dual fuel kit.

I don't deal much with Rhee/Ruud so I don't know what they're making today. We do alot of commercial repairs and replacements and still do a lot of 460/480v stuff.

Get the 480v unit and make things simpler. It will free up time to do other work. Those little conversion details will eat your lunch and suck all the joy out of life if not bid into the job up...

It's possible to tie backup power to run anything you want. The issue of concern is backfeeding the power grid and electrocuting someone while they're trying to fix a power issue. Interties into...

I find the cost of housing is still affordable in certain parts of Austin. Affordable is usually more than you want to pay.

Low cost AC trunk line. Could have been done to fix a problem with air distribution. I agree with Rodney28334. You can make it pretty and wall it off with 2x4's, sheetrock and paint.
