I'm having a mini split system installed by a licensed HVAC installer in a one bedroom rental house. I want to ask those who install these systems if it is important to get a permit to have it inspected? If so, why?

Mini Split (by NE [PA]) Posted on: Jan 14, 2021 5:36 PM

We don't and we have had tons put in. I can't speak for you out there. Around here all we need is a power source and a disconnect outside. They work off of that to install the unit and that's really all there is to it.

Ditto what NE said, only exception to what he said is I only installed 3, but I did them myself, no inspection.

I do whole projects with no permits,just a waste of time and money,i have heating systems replaced all the time with no permits

All real estate is local. Depends on your local permit offices, officers.

What exactly does a permit get you? Around here the inspector doesn't even know what to look for.

What it gets you:

Permit fee

Flag to tax man to increase your taxes. --69.80.xx.xx

Smaller Heat pump mini splits operate off 120 VAC where larger require 240 VAC power as the current draw is higher. Installation is very critical as all the installation procedures have to be followed where a licensed contractor will be able to install. Always keep the owners manual where some manufactures can be downloaded. Recommended maintenance intervals like when to clean filter along with other important things to do.

Our local school district put in some dugouts by the ball fields. As part of an expansion project, they pulled permits.

City: "You're going to have to redo the dugouts. They're in violation of code."

School district: "But we pulled permits and your inspector passed them off!"

City: "They're not up to code. You have to bring them up to code."


City: (no response)

Thank you for your responses. It looks like the licensed contractor should know what theyre doing.

I had several problems with some of the guys who are installing Mini Split systems dealing with the electrical voltage and loads.

Some higher BTU units use 240 volts while the lower rated units use only 120 volts.

When they go to wire these units in older homes, sometimes there isn't a ground wire or the old wires are Under Sized and attach to a second circuit in another room.

So when a tenant goes to turn it on it will trip a breaker when the companion outlet is being used. After so many tripping and over working the starter in the compressor, the unit fails.

SO I check the gauge of wire #10 or #12, the distance traveled, ground and make sure this a/c unit has it's own breaker not shared with anything else.

This is the only reason for a permit, to make sure the job is done right. But running a separate line for this a/c unit can cost a couple hundred bucks to $1,000. Not cheep to get it done right.

I have had two. One was installed as emergency and the installer never got the permit. Five years later it broke and I got a reputable company to replace it. Both needed 240 electric so you should probably make the contractor get a permit making sure you have the proper voltage. I already had a 240 for a window AC but they had to get to it and put in fuses on the outside. The first one was 1500 and the second is a Mitsubishi and was six thousand. Huge difference in size of compressor outside. I have another small one on second floor of a duplex. It's a Fujitsu and has been very reliable.

ABOUT contractors. Don't think for a minute just because he is licensed that work will be OK. When I started out, especially with AC work, I trusted them--- holly mackerel that was huge mistake. Brought a torch, silver solder, Freon and gages. Opened up (hvac) accounts all over town and on line (just like I do for banks and credit unions).

Found out quick that 89.00 capacitor wERE only 7.89. He had it on his truck but still drove 2.5 hrs to get another.

So contractor-- don't get cozy-- unless it's Robert from CA.

Remember they all have "HELPERS" DOING THE WORK.

Mini Split (by Pat [CA]) Posted on: Jan 15, 2021 4:51 PM

I had a licensed electrician come out before the contractor installed the mini split. He made sure it has its own breaker and checked out the wiring. I'll let you know if I have any problems with it. Thank you.
