DIY-ing Our Ductless Warmth Pump Set up Was Exhausting, However We Saved $7,000

Help CleanTechnica’s work by a Substack subscription or on Stripe.

Final summer time I did one thing very bold. I DIY-installed a ductless warmth pump system nearly fully solo. And it wasn’t only one easy ductless system, it was 5 indoor ductless warmth pumps (3 of them on a second ground) and two out of doors models. I’d by no means achieved something prefer it earlier than, however needed to check out how accessible warmth pumps are for the DIYer and the way a lot cash we might save. Spoiler alert: it was actually difficult and consumed a few week of my life, however I used to be capable of full the job efficiently and saved round $7,000.

Why DIY A Warmth Pump Set up?

Why would I tackle one thing as bold as DIY-ing a ductless warmth pump set up? First, I used to be inquisitive about how real looking, accessible and user-friendly a DIY ductless warmth pump equipment was. DIY-ing a warmth pump water heater was fairly doable, would a warmth pump be the identical? I additionally needed to study extra concerning the ins and outs of those techniques and the general course of of putting in them.

However saving cash was most likely the largest purpose. In 2021, we’d bought a ducted, complete home warmth pump on one facet of a household duplex in Cleveland for $12,500.

This has been a fantastic system, however we needed to see if I might lower your expenses on the duplex’s different facet which had an historical, 35-year-old gasoline furnace on its final legs. We had gotten quotes for ductless warmth pump installations for over $15,000 in 2021, and didn’t really feel like we had the finances to spend that a lot cash on changing the heating and cooling system on the opposite facet of the duplex. A DIY equipment regarded about half the price and was very tempting.

My third and ultimate purpose was that I needed to have cooling immediately within the upstairs degree of this facet of the duplex. Our complete home warmth pumps on the opposite facet (together with actually any AC) can wrestle to chill the upstairs ground of the home. So we elected to go for many ductless models to convey cool air immediately upstairs.

Shopping for The DIY Ductless Warmth Pumps

I made a decision to make the leap and ordered a DIY Mr. Cool warmth pump system from a web based distributor final summer time. The full value for 2 out of doors models and 5 indoor models was $6,500, a considerable financial savings, although we’d spend a further $2,000 on some labor assist and components. The system arrived in containers on a giant pallet in mid-August.

Now, I ought to point out that I contemplate myself a 4 or 5 on a scale of 1 to 10 for being a helpful DIYer. I’ve achieved lots of tasks on my home previously, however don’t have nice information, craft, or instruments. To organize myself for this bold undertaking, I watched lots of movies forward of time and skim over the instruction manuals rigorously.

I additionally tried to seek out somebody with extra HVAC expertise to help or probably lead within the set up. Right here I discovered an essential lesson, it was subsequent to unimaginable to seek out extra assist as soon as we’d gone down the trail of a DIY set up. I known as a half dozen HVAC contractors, however all of them expressed a fear about being accountable for tools that they didn’t order. None of them needed to assist out on our undertaking. I additionally figured that these corporations most likely make a big margin on the tools and aren’t thinking about installations the place they don’t present it.

So I nervously set off to undertake this large set up solo.

Indoor Unit Set up

Putting in a ductless warmth pump system includes first drilling a 3 and a half inch gap by the home to move the refrigerant traces and communications cable for each indoor unit. That is, for sure, intimidating. My first couple holes went effectively however after the primary two, the method began taking without end. I later discovered that the outlet noticed I used to be utilizing was nearly fully stripped and so by the ultimate gap or two have been brutal. This can be a hazard of DIY-ing. With out lots of deep background information in instruments, little errors can sluggish a undertaking down significantly should you don’t have the expertise and information to acknowledge what’s occurring and regulate.

As soon as the holes have been achieved, I put in the indoor unit on a mounting bracket and handed the communications cable and refrigerant traces out of the home.

This all went fairly effectively and I felt perhaps a bit too cocky after putting in the indoor models considering to myself, “wow, I can drill a gap right into a home and mount an indoor unit, I should be fairly helpful.” There was lots of hardship forward, nevertheless.

Outside Unit, Refrigerant & Condensate Strains

Turning my consideration to the out of doors models, I mounted brackets to the home to carry them. Right here I had assist from a handyman neighbor. Subsequent, I linked the refrigerant traces from the indoor unit to the out of doors unit. The trick with a DIY warmth pump equipment like Mr. Cool is that it’s a must to measure and order refrigerant traces which might be lengthy sufficient to attach every indoor unit to an outside unit. The pre-charged refrigerant traces are available varied sizes and you’ll most likely have additional (since you don’t need to order too little) and so then should coil it subsequent to the out of doors unit.

You additionally run a condensate line and wire the facility and communications cable to the out of doors unit.

The massive problem for this half for me was putting in the housing that holds (and goes over) the refrigerant traces, however this ordeal was self-inflicted. Reasonably than shopping for the Mr. Cool housing which I assumed was too costly, I purchased a generic competitor to economize and this ended up being a mistake. It was very difficult to suit the refrigerant traces within the generic housing as they have been most likely too small for my job. I ran out of time and needed to rent a helpful individual to complete putting in the housing. They did a pleasant job however value $1,000.

Wiring The Outside Unit

Lastly I needed to run energy from the panel to the out of doors models. I wanted two out of doors models for my 5 ductless warmth pumps, and fortunately certainly one of them was in a position to connect with the previous air con electrical field. I needed to run a brand new wire for the opposite out of doors unit. I had by no means achieved this earlier than and right here I “obtained by with a bit assist from my pals” as my wonderful electrical engineer neighbor Glen took pity on me and helped out with this course of as I used to be operating out of time. We spent one night working till midnight to complete {the electrical} a part of the undertaking. One massive problem was that {the electrical} wires that Mr. Cool advisable have been too massive to connect with the unit. Glen considered a workaround and if I hadn’t had Glenn’s assist I’d have most likely spent a big time with buyer help from Mr. Cool.

After most likely 60 to 70 hours of labor, the models have been put in and have been working rather well for nearly 18 months now. Friends in our Airbnb say they love having warmth pumps in each room.

Curiously sufficient, I get a facet by facet comparability of the ducted vs. ductless warmth pumps on both facet of the duplex. In my view, the ductless work higher for 2 massive causes.

1. Upstairs cooling: In the summertime, the ductless warmth pumps convey cooling to the upstairs of that unit so a lot better than the ducted. It is not uncommon in houses with two or extra ranges for any form of AC to wrestle to convey cool air to the second ground. Ductless warmth pumps convey tons of cooling to the second ground rising consolation considerably.
2. Utility payments: Final winter was one of many coldest in years on the East Coast. These ductless warmth pumps not solely carried out effectively with none backup electrical resistance, they actually used half of the power because the ducted facet of the duplex offering for an interesting comparability of power use and utility payments (which I’ll discuss in a future article).

Ultimate Ideas

DIY-ing your ductless warmth pump set up may be very difficult. In case you are somebody like me at a 4 or 5 out of 10 handiness degree, you’ll be able to most likely do it, however it is going to take some time and can be arduous.

My massive mistake was that my first expertise putting in ductless warmth pumps concerned so many indoor and out of doors models on a two-story home the place I needed to stand up and down a ladder many instances. I would sing a distinct tune if I had tried this with one unit in a transformed storage.

On the nice facet, I discovered a ton about warmth pumps and I used to be capable of save round $7,000 on the set up. My whole undertaking value got here to $8,767 (not together with my time, in fact) for a pleasant system that’s each clear and environment friendly.

I don’t assume I’d do such an in depth system once more, however would contemplate our one or two indoor unit system sooner or later. Have you ever DIY-ed your warmth pump set up? Tell us your expertise within the feedback beneath.
