Why is having a whole-home standby generator important in New England?

With the wildly different weather conditions, we experience here in the Northeast, power outages are no uncommon occurrence for many of us.  As past winter storms have proven to us before, homeowners can be left without power for days or even weeks in our region when they get bad enough.  This can leave our homes vulnerable to damage from things like frozen pipes, and without essentials like running water if you live on a well.  A few of us might even have a portable generator tucked away in storage just for this, but they can be loud, smelly, and dangerous to operate if you don’t know what you’re doing.  Not to mention the hassle of playing the “guessing game” to see which breakers you can switch back on.  Standby generators will truly power your entire home, so you can stay connected and weather the storm with all your comforts!  And since whole-home standby generators are a permanent installation with their own fixed fuel supply, trudging outside in the rain and snow is a thing of the past.  They offer a true set-and-forget package that kicks in so quick, you may not even have noticed you lost power!

FAQs

  • Does my generator need maintenance?

    Just like all of your other comfort systems, whole-home standby generators are working for you even when you don’t realize it! Since they need to be relied upon to turn on in an instant during a power outage, your unit will periodically run short test cycles to ensure everything is working, usually once a week. Overtime, running test cycles and being exposed to the elements means parts will begin to wear down. Weather conditions will also affect the life of your generator battery, which it needs to supply your home with constant and uninterrupted power. Thankfully, routine annual maintenance will replace any worn components and make sure your home’s power never skips a beat!

  • What happens during generator maintenance?

    • Oil change and filter change
    • Check and clean spark plugs
    • Clean air filter
    • Battery test
    • Date/time exercise check
    • Output voltage test
    • Transfer switch test
    • Mock outage test
    • Inspect fuel lines and ensure adequate supply
    • General wear and tear inspection
  • What can I do if my generator doesn’t turn on?

    If you have routine maintenance done on an annual basis, you shouldn’t ever have to worry about this, but very rarely this can happen for a number of reasons.  Most modern generators (including all Heritage installed models) have digital displays to easily inform the homeowner or technician of any potential problems.  If you have a power outage and your generator isn’t turning on, make note of the error code that is being displayed (if any) and give us a call right away!  You can also refer to your owners manual to see if the issue was temporary and the unit just needs to be reset.  If this is the case, your unit should work immediately after the reset.  NOTE: DO NOT attempt to open or disassemble any components of your generator without professional assistance.

Called on a Thursday with an active leak…actually a drip…found by luck on the cellar floor. Vinny showed up less than 24 hours later, and after diagnosing the issue found the problem. It wasn’t what I thought, but his perseverance paid big time dividends. On a Friday early evening Vinny made a trip to a Home Depot 30 minutes away, and when he returned the problem was solved in 30 minutes. Heritage upgraded our electrical system from 100 amp to 200 amp, and installed a whole house generator for us during the winter, so we were very familiar with the company. I can’t say enough good things about their workmanship, their customer service, and their professional employees. I would be pleased to have Vinny come back should the need arise. He was great!!
