"Punctual and professional. All of the work was completed right on schedule. They upgraded my entire home and replaced electrical panel. Definitely hiring again; I have them scheduled to repair the sprinkler system electrical work and the fans in both my bathrooms. The cost was surprisingly affordable! I cannot recommend enough."

"I have only good things to say about the good staff Patrick and James and Anthony and Jean in the office. The problem was with the Generac trickle charger for the battery which starts the generator when the power goes off. Patrick tracked the cause of the problem and Anthony fixed it in short order after a small delay in getting a new part. Jean in the office kept me informed and is very pleasant to deal with. This group all seem eager to please.

"He was on-time, but was frustrated that there was no parking due to all the snow.  He was going to cancel, but we were able to find him a spot.  Initially he seemed a little annoyed with the circumstances, but ended up being really nice and helpful.  He had never installed a microwave before, so he was going through the directions along with me, but we got it up.  He patched up a hole we had, then a few shelves.  We ended up getting along really well, and he was kind enough to split his time within two visits, since we didn't have one of the items that we initially thought we would have. 
Overall it was a really good experience.  It was a rocky start, but after we got over the parking situation, he was professional, and really helpful with everything we needed from his end.
We were very happy with their service, thank you!

Generator Install questions, answered by experts

Setting up utilities on a vacant property usually takes at least a few months, or between 6 weeks to 16 weeks. This process requires working with the local planning and zoning department, hiring a building contractor or engineer to design the utility layout, securing permits, laying the lines, and connecting the utilities.

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.

Natural gas generators are designed to run for extended periods of time, such as power outages during a natural disaster. Since there’s no limit to the supply of natural gas, they don’t need to stop for refills. However, generators do need maintenance, including pauses to check and add oil. Constantly running them will also cause a lot more wear and tear, leading to a shorter lifespan.

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.

Carbon monoxide emissions aren’t only dangerous to human life, but they also harm our planet. While natural gas generators emit lower levels of CO than other fuel sources, there are still ways to reduce emission levels. For example, shop around for an eco-friendly generator that complies with current emission standards. Also, make sure your generator is serviced regularly to avoid CO buildup.
