Is it difficult to replace an Air Conditioning Unit for my home

If its an exact replacement.its approx. 2 to 4hr job.We love these because it highly profitable for the installation tech.Disconnect power., low voltage. duct work. Slide old unit out of the way. slide new unit into place.Connect duct work.power, low voltage.Read all instructions with unit and then enjoy a job well done. GOOD LUCK!

I would listen to Maru and hire someone else. In order for an A/C to run at it is rated SEER value it must be dialed in exactly using very expensive and accurate equipment. Self installation is not recommended. If you live in the south this will end up saving you money in the long run if you get a good HVAC man.

Not enough info. I recently wired a 20 unit condo/office complex and had four different amperage to deal with. You need to get a spec sheet on unit and compare it to existing wiring. If it does not match it needs to be changed not rigged.
Have a pro look at it if you are not sure.

First of all, the amount of freon that comes pre-charged in the condensing unit is only sufficient for a certain length of copper pipe & takes only a certain amount of rise into consideration. There is no way anyone can tell u the precharge is satisfactory without knowing how long ur copper lines are, how much they rise to ur air handler or how many turns the lines make before they get there. I've installed hundreds of units & the odds r that the precharge is not going to be sufficient.

Additionally, 4 hours of vac time means absolutely nothing. You have to pull down to -30 on the compound gage & it has to stay there on its own while the vac pump is off. Not only does this ensure all moisture is removed from the system, but it also ensures moisture can not get back in.

My advice is that if u really want to save money, have someone who knows what they're doing do it. And not just anyone. Talk to their customers first.

Although the work itself is not all that complicated, the knowledge of doing it right is complex enough that even people with a year or two of experience still do it wrong. It is possible to damage the compressor because of install mistakes. The odds r also very good that ur system will be much less efficient, wasting energy & costing u heaps of money in the longhaul. You will void warrenties & u may have a hard time finding a service technician that will even touch it at that point, at least one that will charge anything close to a reasonable price.

You may end up spending $1000+ on top of ur original investment simply because u did not know one of the hundred, stupid little things an experienced tech knows when doing an install like this.

Easy to do & a huge savings.
First the AC/Heat pump compressor unit is FULLY CHARGED WITH FREON so dont go buying any of that stuff. Here is what to buy exactly.
1. proper size heat pump compressor unit in tons & Voltage. (Heat pump is an AC with a reversing valve built into it.)

2. A brand new Line Set of sufficient length.

3. A brand new ''A'' coil with the proper size orfice. An orfice size will be give in the literature of the compressor unit.

Be sure to use the proper size Orfice in the A coil. That size is given in the compressor installation manual which comes with every unit. Install that before going to brazing in the line set. Its located in the A coil itself on small line (high side)

A map gas torch with map gas + oxygen bottle. to braze the line to the compressor & to the A coil. Use a SELF FLUXING ROD called SILFOSS OR SILPHOS (silver + phosporous rod) No flux required & u cannot mess up. Just heat that slip connection red hot & put the self fluxing rod to it. IT NEVER LEAKS. Ive done at least 50 of these in my apt complex for maintenance & NOT A SINGLE LEAK. So dont go using no propane & solder or those quick disconnects. Welding supply has Silfos.

You r nearly done except for pulling a vacuum. Rent a 2 stage vacuum pump. Hook it onto the the connection at the compressor specific for that to pull a Vacuum on the ''A'' coil & the line set. Leave that vacuum pump on there pulling out moisture for at least 4 hours. That will dry out the line & A coil. Remember, that compressor unit is fully charged with freon so no vacuum is required on it.



Now shut off the pump & leave a vacuum on the line set & A coil dont release the vacuum. Then open slowly the valve on the compressor unit to release the precharge of Freon to the whole system. There r 4 valves total. 2 on the LOW side & 2 on the HIGH side or exit from the A coil side. Open all 4.

You r DONE The precharge of freon in the unit is preset for a normal 25 foot lineset & no additional charge is required. You can now run the wiring for the unit. There is a schematic on the backside of the furnace door & the backside of the electrical access panel to the compressor unit. No other instructions r needed. It will show the 220, 110 & small wire 24 volt thermostat connections right on there so u can procede with full confidence.

You can buy surplus AC equipment at usamfg.net for pennies on the dollar. I have delt with them for years. Brand new slightly damaged equipt. To get the good price establish an account with them thru ur business address.

It is not even necessary to change out the thermostat. Wiring is according to an industry standard, but make sure you shut off the power before you begin (I assume it 220 volt). The wiring should be the same as the old unit. Black is hot wire, white neutral, and green is ground.
The biggest concern youhave should be in making sure the unit sits level, drains properly, etc.
I think you can handle it! Good luck
