"We were so lucky to have Marella respond again to our Home Advisor Inquiry. We had used these excellent guys before and loved them , but lost their card and so we couldn't re-contact them for this project. Once again, we were totally satisfied. They are courteous, prompt, efficient, and offered us the best price for the install. Believe us, you won't do any better than Marella Electric."

"Ken is the best. I definitely now consider him my electrician. I would not dream of using anyone else. He drove an hour to me on a weekend at Christmas when I had no heat and hot water. Do I really need to say any more than that?"

"We received excellent service from NILES HULL, who performed a pipe repair for a hose attachment in our driveway. The job was $533, and was done well, with pleasant, knowledgeable service. I highly recommend Harris as we've used them for many plumbing and electric projects in recent years. NILES HULL was knowledgeable, caring, and attentive to detail. They stand behind their work.

Generator Install questions, answered by experts

With proper maintenance, a whole-house generator can last between 20 and 40 years. The specific lifespan depends on how often and for how long the generator is used, and some models may have their life expectancy rated in hours of operation. To maximize its lifespan, expect to spend around $150 to $300 per year for annual maintenance checks from a qualified technician. During these checks, a technician will inspect the engine filter, starting mechanism, fuel, lubrication, and coolant levels. Consulting your installer and choosing a low-impact fuel like natural gas or diesel can also help ensure your generator lasts as long as possible.

Costs range from $500 to $2,500, depending on generator type and installation complexity.

Sizing a generator is a careful process that requires calculating the electrical load of your entire house. You have to take into account every device you want to use and their wattage requirements, plus the wattage needed to start them, and look for a generator that can safely run all that at around 80% capacity.

In more practical terms, a small home can run on a 10,000-watt generator (and if you only want to power a few key appliances, much less than that). A mid-sized home may need something between 15,000 and 22,000 watts. Larger homes require 25,000 watts or more. 

While standby generators provide essential backup power, they can fail when you need them most due to lack of maintenance, fuel supply issues, dead batteries, electrical problems, or improper installation. To avoid costly failures, professional installation and regular maintenance are crucial. Licensed technicians ensure safety, uphold warranty requirements, comply with regulations, and provide expert servicing.

No, you should never plug a generator directly into a wall outlet in your house. This practice is extremely dangerous, often illegal, and can cause "back-feeding," where power from the generator flows back into utility lines, creating a life-threatening hazard for utility workers. It can also damage your home's electrical system, including appliances like pumps and HVAC fans. If the main power is restored while the generator is connected, it can destroy the generator and cause an electrical fire. To safely connect a generator, you must use a professionally installed transfer switch or an interlocking kit, which prevents back-feeding by disconnecting your home from the utility grid before the generator provides power.
