Go get you a 6 or 7 cfm JB Platinum pump. Not the cheapest but they are good durable pumps.

I have been having problems with a Magnatech Braided Hose Freezer. The high stage compressor runs R-134A and the low stage runs R-23. It will cool down to set point of -70 but it is supposed to reach...

I an going to take the Arkansas Class A HVAC exam on Wednesday, any information from someone who has taken it would be greatly appreciated. I have all the books and have been doing a lot of studying...

Check the connections everywhere. Bad connections generate heat which will trip a breaker even under normal load.

HVAC work can be very demanding on your body. I started doing it when I was 18 and now 20 years later I have bad knees and aches and pains related to work on a daily basis. I took a fall down an icy...

I believe it takes 10 years in the field to become a good service tech. Go to work for someone else first and let them pay for your mistakes. I'm not sure how licensing goes in Florida, but here in...

Thanks for the response. I'm not sure why the coil was replaced. I was given the job after a younger tech replaced it. Is this a common problem? Both circuits are doing it and also one circuit in...

I'm having problems with a Trane YCD150F3H0AA. S/N 114810854D We had a different tech out awhile back. He said he found low suction and high head in both circuits that's about all he told me. He...

thanks for the reply. I never have been a put it off till Monday kind of person anyway and I know what you're saying about server rooms and stuff like that. I have several casinos that I take care of...

I am a commercial HVAC tech with 18 years experience. I have a good job that pays well, the problem is they don't offer any kind of health insurance or retirement. I accepted another job in...

First of all if it was 7 years old it WAS under warranty. But if you just went to a local supply house and tried to swap it out no wonder they told you it wasn't covered. If that's the same motor you...

Call for service. If it is a bad motor, all Lennox signature series variable speed motors have a ten year warranty. Usually it's the motor on the G61 just pay the labor to have it replaced. Quit...

Sounds like a loose panel vibrating. Nothing to worry about but it can be annoying. If it concerns you call a tech to come make sure that's all it is.

The company I work for is a Lennox dealer, not trane, but we take pride in stocking our warehouse and trucks with all the proper parts to better serve our customers. We have parts from the latest...

I have started up hundreds of both. I prefer the xc17, even though they can be hard to service if they are not kept far enough away from the building. But to me they seem a little quieter than the 14.

I wouldn't worry about it. Enjoy the xc25. They are a very good unit. The variable speed compressor is super quiet and crazy efficient. The company I work for has installed a lot of them. No...

Personally I would not waste my money putting a compressor in a 25 year old unit. Sounds like its time to upgrade. But if that is your only option call your local Lennox dealer with the model number...

Let's not forget the most important lesson. Never date or sleep with the cutie that answers the phone and dispatches you to your calls. If you piss off the dispatch girls you will find yourself...

The only question I would have is if your jurisdiction would require a garage to living space wall to be fire rated. 99% of places dont require that but I've heard of some cities in California that...

International mechanical code section 602.3 stud cavity and joist space plenums. Stud wall cavities and the spaces between floor joists to be utilized as air plenums shall comply with the following...

where do you live. There is a company in my area that uses that slogan. Its Heartlands one hour heating and air conditioning.

agreed. I love the prodigy m2 control. I like the test mode on it also. Couldn't agree more to get a cheap laptop for testing. Makes things much easier.

Start by checking the coils and condenser fan motor operation. Depending on the model number some have low ambient fan cycling switches that could be stuck open and not bringing the fans on. Exact...

The only coil recall that I know of involving lennox was older equipment when they were having the green slime issue, but that was only coils that actually had the slime. I'm sure I would know about...

I would call a professional to take care of the problem. This is not a do it yourself repair. Your family's safety is worth much more than the cost to properly repair the problem.

First of all in regards to refrigerant pricing, we buy at wholesale and sell at retail. If your car breaks down and you need a part do you go to the auto parts store and demand a part for what they...

I would not move the furnace to the attic. Keep it in a nice clean conditioned area if possible. I like the lennox equipment but be weary of the harmony 3 zoning system, in my opinion it is not the...

They are both low end builders grade equipment. I would not personally recommend either one, but the Frigidaire is probably the better of the two.

They should still honor the warranty. Make sure they replace the filter drier when they change the compressor. I would also recommend replacing the TXV while you already have the system open simply...

Check your thermostat wiring. If it appears to be correct then I would recommend having a professional come out and look at it. Like cjpwalker said if there are no zone dampers, what does the second...

You are definitely over thinking. You can't expect to throw together a bunch of used mismatched crap and expect it to work like a properly designed system. Its just not gonna happen.

Welcome!

That's hilarious

I do both. About 80% of the time I am running commercial service calls. The other part of the time I am on a new construction job site in my hard hat and safety glasses installing controls,...

I was actually talking about commercial pm's its kind of hard to stuff 100 2" filters in a trash bag. I always ask supervisors if it is OK to use the dumpster. I've never had anyone have a problem...

I was wandering if I can post pics with my posts from a mobile device. If not how do I do it on a regular computer. Thanks in advance.

My van is always spotless. It was brand new with only shelves in it when I got it. I stocked it the way I wanted it and I am anal about removing trash and old parts everyday. I also restock every...

I'm guessing a restriction somewhere or a condenser fan motor failure.

I've used it once on an older system with a very small evaporator coil leak. I explained to the customer it was a last resort and I couldn't guarantee the results. They were older people on a fixed...

Nothing worse than going on a call with leaking Schrader cores and the guy before you used leak lock on the caps because he doesn't own a Schrader core removal tool. It sucks trying to change...

Just seems like a lot of trouble carrying all the different sizes. I'll stick to my 15% rod for now. I'm usually the last guy to try new things until they are field proven for awhile. Same reason I...

The Lennox SL280V model has a GE motor and it comes with a ten year warranty on the motor. As with any variable speed unit, I would reccomend a high quality thermostat to control it.

That's probably what I would do if I were you. Call a reputable company that gives free estimates to come out and look at it and go over all the options with you.

I will work in a light rain but when the lightning and heavy rain starts I'm off the roof period. I will wait about thirty minutes in the van or peek at the radar to see if it will pass soon. If not...

I'm not a fan of silver tape at all unless you are taping exterior insulation seams. It just looks tacky to me. Use clear silicone where exposed and use a brushed on duct sealant in soffits, attics,...

That should have said two different split systems. Damn auto correct.

I'm not sure you understand what a zoned system is. In your instance a zoned system would be one air handler and one condenser that use zone dampers in the ductwork to control the temp in 2 different...

If I this a heat pump there would have to be some sort of metering device in the outdoor unit for heating mode.

Have the installing contractor come and look at it. A loud bang is not a normal compressor sound.

I'll fix that son of a *****! Anyone got a 10,000,000 foot extension ladder I can borrow!!
