At MillTown Plumbing, Heating, HVAC, and Drain Cleaning, we're a family owned and operated business. We know the value of fast service, from a professional and reliable team. Give us a call today at (617) 725-2674! We look forward to serving you.

"STAY AWAY. Numerous issues and they will cost you more money without you knowing it. I just found out that I was on a **DO NOT SERVICE** list (after all the grief they have given me.) I am ticked off. Here is a summary due to the character limit: 1. They installed a faulty HTP tankless hybrid water heater. I argued with them for what I think was a good year before a HTP tech finally determined that I was right. Replaced it with a Rinnai RUR199in. 2. They took (stole) my oval ductwork and replaced it. I was fine with the replacement. I looked the other way but it was expensive and they never asked - they just hauled it away. Most homeowners probably do not realize how expensive and unusual that oval ductwork is. I could have even recycled it at a profit. 3. I recommended them to a neighbor only to find cops all over their home one day. Their plumber stole their special needs kids controlled medications after having them go into other rooms to turn on and off the faucets. I just chalked it up to a bad apple. 4. HUGE ROOKIE mistake. They short-cycled the new air handler. Vent was right next to the main return (2in. away.) Unecessary wear and tear, high electric and gas usage, and discomfort. Whatever was coming out was immediately suck back in. Unfortunately I did not realize this until a couple years later. 5. HUGE ROOKIE mistake. They never installed the 2-stage wiring. See directly above. Look it up. HUGE discrepancies in temperatures and sky high bills. Premature wear and tear. I wrote Freddy Jr. about this which might be the reason why I am on their list. But still, that is their job to get it right and not mine. Most people would have no clue for the life of their system. 6. They did not hook up the high-limit kill switch/float on the condensation pump which led to a flood and destroyed antiques. I hooked it up in less than 10 minutes. 7. I was told one day that the original manger was fired because he was skimming clients from the company. 8. There is no check valve on the recirculation line which they installed on the new tankless they replaced. I believe it is code and now I have to hire someone else ([business name removed]) to fix their screwup which likely killed my internal recirculation pump. Again, unecessary wear and tear along with high energy bills. I was willing to look the other way on so many things but the truth is they get away with this because most homeowners do not know any better. In other cases, I figured that no one is perfect and we all make mistakes. But then to find out that I was blacklisted a few years later because I called them out on their BS after I needed their help yesterday? The only thing I can think is that I ended up costing them more money on things they should have done properly in the first place. It is a company that needs better oversight and apparently has awful management. I am not bragging but I have an advanced engineeering background creating petroleum engineering training material for big oil (aka plumbing on steroids--makes this look like childs play), programming, developing systems for hydroponics, working with heat and waste recovery systems, fixing combustion engines, and building computers for over 20 years. My point is that I noticed a lot of things that most people would overlook because I know how many things work. I called them out and that is the only explanation as to why I could have been blacklisted. But do yourself a favor and go with [business name removed] or [business name removed] instead. It is not to say that others cannot screw up, but this is my experience with them and the straw that broke the camels back. Mention that you read this here and thank you. Perhaps the next company will not mess you up under the guise/protection of teamsters and protectionist unions that overcharge with ridiculous licensing requirements that ends up meani..."

We have a baby so they were able to work quietly while our baby napped right on top of where they were. They were precise and explained everything thoroughly. They kept the area cleaned and cleaned up after too. The living room, basement and garage was done in half a day. Excellent! Can’t recommend Castro Electric Corp enough!

FAQs for generator repair projects in Dunstable, MA

A standard electrical meter riser replacement takes an average of two to three hours for the actual installation work, though the entire process may span a full day. This timeline includes coordination with your utility company for power disconnection and reconnection, the physical replacement work, and any required inspections. Weather conditions and permit processing can affect the schedule. Plan for a day without electrical service while the work is being completed.

The homeowner is responsible for maintaining and replacing the electrical meter riser and related components on their property. While your utility company owns and maintains the actual meter and the service lines leading to your home, everything on your side of the connection point—including the weatherhead, riser pipe, and meter base—falls under your responsibility. This division means that when damage occurs or upgrades are needed, the homeowner bears the cost of replacement.

Yes, your power must be disconnected during an electrical meter riser replacement. Since this work involves your home's main electrical service entrance, the utility company will need to disconnect power at the service drop before the electrician can safely begin work. 

This outage lasts for several hours while the replacement is completed and inspected. Make appropriate arrangements for perishable food items and consider alternative accommodations if the weather is extreme.

If you're simply replacing a damaged meter riser without changing your electrical service capacity, you can often keep your existing panel. However, if you're upgrading from a lower amperage service to a higher one, you'll likely need to upgrade your electrical panel as well. Many electricians recommend evaluating your entire electrical service during riser replacement, as combining these projects can be more cost-effective than completing them separately.
