HVAC technician installs a $429 heat pump in his cabin after a quote topped $4,000

The installer said he used nitrogen purging and pressure testing.

An HVAC installer said he was able to heat and cool his cabin loft with a $429 heat pump after a distributor quoted him more than $4,000 for a different system.

What happened

According to his Reddit post, the Temprium unit costing $429 was the final pick. Before buying it, the installer said he had looked at a basic Daikin model on Amazon for about $1,400 and a Daikin indoor-outdoor setup that came in at more than $4,000.

He said he also added upgraded refrigerant lines, wiring and a drain line. The $429 figure covered only the unit, not what he would usually charge for the full job. After the installation, he said the budget system worked for both heating and cooling, though he found it louder and less solidly built than pricier options.

More context

The original poster started the discussion with a statement that can make some DIY installers pause: "Potentially hot take: pulling a vacuum is one of the easiest parts of installing a heat pump."

Other commenters responded with opinions on installation costs and whether the poster had properly checked that step.

The discussion included personal cost estimates rather than fixed pricing. One commenter said a broader set of installation tools could cost $500 or less, while another compared an option around $1,100 with a $1,649 quick-connect DIY kit.

Upgrading heating and cooling can be one of the most effective ways to lower utility bills and cushion the impact of rising energy prices. Even so, the cabin owner's experience highlighted equipment prices rather than actual electricity savings.

The unit price, extra materials, installation know-how and ongoing operating expenses are all separate considerations.

What people suggested

For homeowners considering a DIY project, commenters stressed the importance of verifying the installation instead of cutting corners.

Several participants challenged the original poster's choice to skip a micron gauge, saying the tool is useful for measuring the vacuum. The installer said he used nitrogen purging and pressure testing.
