Pros and Cons Of Whole House Generators

When there is an outage, food spoils, pipes freeze due to the lack of heat, you cannot do work on your computer, you cannot operate your kitchen appliances, and many other things are out of order since all require constant power. 

There are many solutions to this problem, and generators are one of them. Portable generators, power stations, and standby generators can be a backup power solution when there is power cut off. 

Standby generators are mostly used and known as backup power solutions. They are installed on the whole house and provide instant power to your home when power is cut off from the primary source. Standby generators are also called whole house generators as they light up the whole house. 

What benefits the whole house generators and what are the cons associated with them are the main focus. Let’s look at the pros and cons of whole house generators in this article. 

Pros Of Whole House Generators

1-No Fumes and Carbon Monoxide Accumulation 

Whole house generators mostly run on propane or main pipeline of gas. Unlike portable generators, they don’t produce fumes, carbon monoxide which is lethal and can kill a human within a minute if it builds up in the living space. 

2-They Can be Directly Operate On Natural Gas Pipeline 

Mostly portable generators are operated on gasoline or propane. It requires frequent refilling of fuel when it gets out of fuel. 

The process requires shutting down the generator, refilling it upon cooling and then starting it again, and it takes time and effort. 

In contrast, the whole house generator is installed on the main pipeline which never runs out of fuel and turns on/off whenever the main power is returned or goes off. 

3-They Automatically Start and Turn Off

In portable generators you have to start the generators manually either by recoil, push start, or in some generator remote start, but you will not get uninterruptible power supply which is required by most appliances for their proper functioning.

While whole house generators trigger automatically upon power cut off from main supply and provide uninterruptible power supply. They also automatically turn back to the main supply when power is restored from the grid. Ultimately you will get power without going to any hassle. 

4-Built in Transfer Switch Prevent Back Feeding, and Surge Protection

Portable generators require a proper transfer switch installed on the main circuit board if you want to operate it on the main board. Surge protectors should also be installed to save connected appliances from a surge of generators. 

Incase of whole house generators you should not be worried about transfer switch and surge protection. Both of them are pre installed in the whole house generators for smooth transition of power from generator to grid and vice versa plus surge protector protects from surges.

5-Save Money In a Longer Run 

A refrigerator without power spoils food, pipes freeze, you cannot operate appliances, and instant power cuts damage appliances as well. The consequences are costly.  

Cons Of Whole House Generators


In terms of size and wattage, whole house generators are much bigger and installed on the main supply that cost a lot up front. 

2-Required Large Space

In order to install a whole house generator, you will need a lot of space from your home. 

3-Advance Plumbing and Electrical Skills

Whole house generators are installed on the main circuit board and they are installed permanently. That is why it requires special skills of plumbing and electrical for their proper installation. 



This is because whole house generators are bigger and have more wattage, which makes them a little noisier than portable generators. 

Final thoughts 

A whole house generator can provide power during power outages and keep your appliances powered up. They are a little noisier than portable generators. 

The refrigerator keeps running, which prevents food from spoiling. A transfer switch prevents backfeeding, an automatic on/off generator, and a surge protector protects connected equipment from damage. 

Installing and maintaining a whole house generator is expensive, and requires advanced electrical and plumbing skills.
