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.

They responded quickly to my emergency service call and sent Dennis Parker the same day. He was pleasant to work with and explained my options well. Once the extent of the problem was understood, I asked him to only do the necessary work for now. He responded with a short term plan that gave me what I needed. I will ask for him in the future, to complete the work, and for other service calls.

2026/may5 update: Dennis and Richard came to the rescue today and fixed a gas leak. They found the leak and also figured out how it happened in the first place and fixed that too. 2026/feb Update: Today I had an awesome plumber from Landry. Randy came out to a home we bought ten days ago. We had nothing working in the bathroom and an ancient something or other in the basement. He said 3 hours to fix the 3 things. He did it in two hours, all while answering my unending questions about my new home. 2025 update: Had Aaron out to fix out heater, he was great, he set out three options like Landry always does and gave good advice for our situation. When he changed a part he found that the old one was working good enough for an emergency and left it labeled with a date on it. He was so organized and knowledgeable. 2022:These guys fixed so much stuff I didn't know existed and brought everything up to code. They put in a new water heater that I never have to worry about and some water pressure control thingamajig and fixed the insane vent thingy the former owner of my apt made out of chimney parts.

Julian did an outstanding job replacing my old central AC with a cold-climate heat pump. He worked hard and stayed late, getting the job done in just two day. It is clear that he takes immense pride in his craftsmanship. The setup is clean, professional, and organized. Most importantly, everything works perfectly. The system is running smoothly, efficiently, and exactly as promised. Tim was also great. He help me pick the right system and guided me through the process of qualifying for the Mass Save rebate and 0% loan. I am incredibly grateful to the entire Landry team for making this such a smooth and stress free project.

I cannot say enough about Landry and their crew. Gavin, Anthony, JT, and Mike did a phenomenal job installing our mini splits. They showed up on time, stayed late, and worked clean. Unfortunately, My husband had a medical emergency while they were working and they stepped in and handled the situation until help arrived. If they didn’t step in it would’ve been so much worse. We will need our boiler and hot water tank replaced in a few months and will be calling Landry back to do the work. We now have a go to company for all of our plumbing needs!
