Whole Home and Standby Generator Installation

If you’re interested in having a generator installed on your property, you may be debating between a standby and a whole home generator. While both offer reliable backup power solutions, each generator type has distinct advantages and disadvantages.

Whole home generators have a higher upfront cost and require more space than standby units. As far as power output is concerned, whole home generators pack a bigger punch. These high-capacity units can provide power to your entire home during an outage.

Meanwhile, the power capacity of standby generators is limited — though usually still enough to operate essential appliances and systems, depending on the size and power demands of your home. Both generator types will power on automatically when an outage occurs, giving you peace of mind knowing your home systems will remain in normal operation.

For superior electrical solutions in Littleton, MA, Landry Mechanical Inc Plumbing HVAC & Electric can help. Call 508-987-0080 for quick, quality service.

Frequently Asked Questions

Hear From Our Satisfied Customers

I have a boiler maintenance plan with Landry. They completed startup service for our condensing gas fueled boiler . My wife & I are retired engineers. Eddy the technician is very knowledgeable and worked efficiently. His customer service skills are excellent! He patiently answered all our questions & fully explained his inspection findings. He quickly put a proposal together, got our approval to proceed and went to get the new parts needed. The boiler maintenance was done in an hour.

And So the boiler is ready for reliable service this winter. Thanks Landry!

Technician arrived right on time. He (Anthony) was friendly, courteous and very professional. Anthony listens carefully to the issues and then provided a reasonable and practical solution. Overall cost was reasonable. My only concern is that it is not easy to talk to a human being during the booking process. Have to go through an IVR then a AI bot. Company could make the engagement process easier and less complicated.

Landry Mechanical recently helped me with a rather stressful issue concerning my main water feed line to my house from the well pump that developed a substantial leak. Techs Nick Gosselin and the other man who I only knew as Ricky, worked tirelessly to get the leak located and eventually repaired. Then a complete water pressure check was performed inside. Nick's go to "dig guy", Mark, from Micheal's Landscaping in Shrewsbury, was also very instrumental in the repair with his expert excavation skills. All in all, a very positive outcome to a not so pleasant situation

Mike was very professional and knowledgeable. He came to repair my Generac generator. He found the problem quickly and offered a few different options for the repair and on going maintenance. No pressure sales tactics, just providing information and letting me choose the best option for me. I will be continuing to do business with Landry Mechanical in the future. I would like the folks at Landry to know that this is my first ever review in my life. I do not make endorsements lightly. I was so impressed with the service that I received today that I wanted to share my thoughts and rating for Landry Mechanical.

This was my second time hiring Landry Mechanical for electrical work. It was a question of determining whether an appliance or a circuit breaker was faulty. The technician (Michael) traced the issue from the breaker box to the appliance itself and, as it happened, the problem was with the appliance. There was no charge for the service. Thanks!

Landry Mechanical made the entire experience amazing from start to finish. The moment I called to make the appointment, I felt taken care of.

Our comfort advisor was fantastic — patient, knowledgeable, and genuinely focused on helping us choose what was best for our home. No pressure, just honest guidance.

The install team who put in our whole‑home heat pump was just as impressive. Professional, friendly, and clearly experts at their craft. They worked efficiently, kept everything clean, and made sure we understood the system before they left.

Every part of the process was smooth, respectful, and professional. I couldn’t be happier with the service we received from

I've been a customer for many years. Every Tech I've had how has been great, they are all polite and ready to service the system I have nothing bad to say about any of their techs. Today I had Tory come out and she did her job well nice little conversation while she's working. Just like I've had conversations with all the previous techs. And I like the fact that the after service email showed me the pictures she took including one of my dog looking up at her. So she's also a dog approved. 😀
