    The reality is that in commercial, the money it takes for new equipment, is usually better spent in another area of the business.
    If you were a real tech, you'd solder a relay on that board and call it good to go.

    And to take it a step further, with some commercial and a lot of industrial, the equipment isn’t coming out without pulling down walls or ripping off the roof.

    I've replaced RTUs not a problem. I've replaced 40 ton compressor with 2 20 ton CUs. Some old commercial Air Handlers you would have to tear things apart but there is times that's even needed depending. Residential and Light commercial it pays for itself. Most of the time when equipment has problems that's new is because it was installed really poorly. Units that were built in the late 90s were a lot better than the 1980s pieces of crap. There are a lot more serviceman friendly. But a residential heat pump 40 years old needs to go

    I would need to se documented proof of that.

    Not to mention commercial warranty on all parts is usually 1 year, with the exception of some compressors being 5 years.

    I cannot possibly see how any equipment he has installed based on his photos would even perform at the rated specs. Probably using more energy than required based on poor design and installation practices.

    I didn't post pics of that job. I gave you the specs on the Old Furnace it was 100,000 BTU input. The new one has 60,000. It was also a two-stage 60,000 BTU 80 % furnace. It has a lot better airflow than the old hunk of junk that was there that was belt driven. Residential equipment has a minimum of 5 years on the compressor many have 10. Only commercial equipments only got a one-year warranty. many commercial have 5 years on them as well on the compressors.

    Or taking out a window on the 25th floor. That was fun. I wish I still had the picture of me sitting on the ledge.

    With alot of the work I'm currently doing at hospitals you cant just replace units. Sure any where else a package unit may get swapped out, but at hospitals its cheaper to replace the coils and compressor than it is to put in a new one. We've done complete rebuilds on package units where the only original bit was the sheet metal frame. Per OSHPD that's fine. The only exception are replacing smaller mushroom exhaust fans that dont serve critical areas.

    Hell as I write this I'm replacing a condenser coil on a split system. Kinda crazy but its an easy 10 hours of OT.

    When I did residential my limit was about 20 years depending on the location. I had a unit that was about 100 yards from the ocean on top of a building. It was 3 years old and the fins were already starting to flake off. That unit would be lucky to make it to 10 years. Granted some of these new coatings look promising but I have yet to try them.

    I'll bet that 99 out of 100 people here reading this don't know what OSHPD is.

    Let's put it this way . . . They are about the only regulatory organization/agency that follows every single rule that is written. Code enforcement for hospitals.

    Yes exactly. I forget not everyone knows who they are. They serve a purpose, but it's a pain when you have to bring engineers in to replace a simple piece of equipment. I've gotten into a few arguments with their engineers. They wouldn't let my foreman into the job site when they were building a new tower because they knew he would call out their stupid designs. Now

    I replaced condenser coils on commercial equipment. If you're talking about incremental units that's not what we're talking about. P tax things like that you can always buy a unit have a spare that runs and then fix the other one. Residential applications unit test 15 years old even 10 if it's out of warranty should just go in my opinion. Replace a compressor in a 10 year old unit especially heat pump has so much that can go wrong with it I don't think it's worth the money it's an easy 1500 bucks for a compressor change.

    Can we all just agree with theklux on the premise that everything has an expiration date. At 550 posts theklux should be replaced on this forum.

    By the way I’ve made wiring repairs to a 100 year old gravity furnace. Maybe I should have pushed a 5 digit replacement including asbestos abement instead of a bill of hundreds. Hmmmm

    You can fix anything with the right amount of time and money.
