Whole House Generators – Key Things You Need To Know

Schedule Now

A whole house generator is rapidly becoming a standard accessory in homes. Weather-related power outages have increased 100 percent since 2003. On an average day, about a half-million people across the country are affected by loss of utility power. Not only are power outages increasing, the typical duration until power is restored is also getting longer. The reason is clear: most of the U.S. power grid was constructed in the 1950s and upgrades have not kept pace with rapidly increasing demand or changes in patterns of severe weather.

Portable generators utilized for recreational activities are not designed to provide safe, reliable household power during an outage; amperage output is insufficient. Units must be deployed outdoors then manually started, and utilization present hazards from carbon monoxide exhaust and the necessity to string long extension cords in wet weather.

Installed by a professional electrician, a whole-house generator safely protects your household from electrical interruptions and the potential expense and stress of having to leave home until utility power is restored. Here are some key facts to consider:

  • Whole-house generators are permanently installed behind or next to your home, and are about the size of a typical central A/C.
  • The unit is hard-wired directly into the main electrical panel of the house and continuously monitors incoming power from the grid. When an outage is detected, the system automatically starts and shifts household circuits over to generator power in seconds. After utility power is restored, the generator automatically switches back to the grid and shuts off.
  • Whole-house generators typically run off clean natural gas fuel already supplied to your home. It’s a self-feeding energy source that flows without pumps and is very rarely affected by weather or other factors that cause power outages.
  • A whole-house generator can be sized to your expected needs. Capacity ranges from sufficient power for critical circuits only to units that totally replace utility power throughout the entire home.
  • Apps available for many whole-house units permit remote monitoring and control via smartphone.

"Ernie & Mike did a superb job on my new furnace and A/C installation. Despite having more than a day’s work to do, they came in and stayed until the job was done. They were organized, efficient, and protected the rest of the house well. Got both furnace and A/C installed the same day. Ernie was courteous, informative, and clearly knew his job better than anyone I’ve encountered before. The units look so good guests now get The Tour of our new system. Apollo is clearly not a fly-by-night company. I would recommend them to anyone in need of a new furnace and/or A/C."

"I called Apollo because of a water leak I thought I had in our upstairs shower going into the kitchen. Robbie came and assured me everything was fine & looked at all the other plumbing. He ended up changing a few pipes for our washer & clearing a drain. He was very nice & knowledgeable with all my questions. I ended up signing up for the care plan & was very happy with my service."

"The team at Apollo exceeded my expectations. As a business owner, my attention to the details and commitment to providing excellent service is high. From the sales rep. to the installation team, everyone’s performance was outstanding. For example, the installation team went to great lengths to protect our floors, placing floor runners and across the wood floors and up the stairs. They even were spot washing walls upon their departure. I highly recommend this company."

"We scheduled an estimate AND a tune-up. We knew something was wrong with our furnace, but hoped we could make it through the rest of the season. Upon telling Bill what our furnace was doing, he warned us immediately what the possible outcome was going to be; a cracked heat exchanger. He watched the flames roll backward, tested carbon monoxide levels, which were so high they meter’s last reading was 5,600 before saying “high”. He immediately shut it down, tagged it, and explained that with levels that high and children in our home he wanted off right away. He continued his inspection and showed us via a camera that not only was it cracked in multiple places, but had holes all over it. He gave us a few options for repairing it; his knowledge as well as genuine concern was beneficial and refreshing. Luckily we also scheduled an estimator, Micah, to come too and we were able to get costs between repairing and replacing (with several options). We decided to replace with a much higher efficiency furnace and one sized properly to our home. Hands down, not only did they both provide us great service and knowledge, but without sounding dramatic, they may have saved our lives. This was our first time calling Apollo, but it won’t be our last."

"Apollo is an excellent company. I always receive great service. Alex A. was professional and friendly. He kept me informed during the process of checking my furnace and heat pump to make sure they were working properly. The company makes sure you are notified who is coming and when they are on the way. All my interactions with the company have been wonderful."
