    We had our HVAC and tankless unit installed by MillTown in 2020 as part of a hydronic heating…read moresystem. A month ago, the commercial‑grade tank they installed failed. Rheem covered the tank under warranty, but MillTown charged $5,800 for the replacement which was essentially a retrofit with minimal changes. After reviewing the work, it was clear the job should have been closer to $3,000 based on industry standards and actual scope. Unfortunately, the workmanship was disappointing. The system was left in a condition that doesn't reflect professional standards -- including a drain valve positioned against another pipe, making it impossible to drain the system properly. I provided photos and a detailed email to Milltown expressing these concerns. Their response was that there "wasn't much to do," and they offered only a $500 credit toward a future service. Given the excessive pricing and the quality of work, a credit for a future service wasn't a reasonable solution, and I declined it. Another concern: their website offers no way to contact the owner or any managers directly. For a company that presents itself as family‑run, that lack of transparency says a lot. Overall, the experience was frustrating from the high cost to the poor workmanship to the dismissive response. Based on this, I cannot recommend MillTown for plumbing or HVAC services.

The lead tech tried to sell us a maintenance plan to get any kind of reasonable discount. Overall, I found their prices way to high. No thanks!! Milltown...people still work for a living. Merry Christmas Slower season? Isn't this heating season (busy)? Nobody wants to pay for you to train your staff.

    I've never left a negative review before, but I feel morally obligated to share my experience so…read moreothers considering mini-split installations can be warned. From the start, the installation process was riddled with problems. Rather than detailing each issue (which the company would likely try to excuse, as they did every time I raised concerns), I'm posting pictures so you can judge for yourself. I strongly recommend getting everything in writing--many verbal guarantees I received were completely disregarded. For example, instead of floor units in my kids' bedrooms, I was given ceiling units, one of which is positioned so low it practically touches my son while he sleeps. Now, as I'm finishing my basement, I had a friend who works in HVAC assess the mess Earth Tech left behind. He estimated it would take 3-4 days and cost around $3,000 to fix. He also explained the risks associated with their work: pipes joined in the middle are prone to future leaks, especially when unsupported, as stress on the joints increases the likelihood of failure. With so many joints, locating a leak would be nearly impossible. Shockingly, much of the system is held together with duct tape. While this may last through their warranty period, it's clear the entire system was designed to last just long enough to shift the responsibility of repairs onto the customer.

    BEWARE! These people were inept or in bad faith or both. Made serious mistakes in the installation…read moreof my Heat Pump that cost me more than twenty thousand dollars.
