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.

Was 3 1/2 hours late for an appointment I made a month ago. They couldn’t even get my name right. No apologies or even an idea when they would be here. Very inconvenient.

Corey Menard is a STELLAR human being as well as an EXPERT HVAC technician! He cheerfully and swiftly diagnosed an in-wall heating pipe burst, repaired it, and added a much-needed shut-off valve for one of my (three) heating zones. My English language dictionary does NOT contain the words I need to express my gratitude toward him, or express my gratitude to Landry for sending Corey to my home on Wednesday 02/11/2026. Thank Corey, thank you, and thank Corey!

From the first message left by Landry Mechanical to scheduling a time for a technician to service my oil burner furnace, I was thoroughly impressed. Aaron Corriera who was dispatched to my home was courteous, professional and thoughtful as he kept me up to speed with each step during the process of servicing my furnace.
