"Mike who I met from Reliable Power Systems (RPS), is professional and personable and went out of his way to treat me and my particular situation well.  Probably due to price and quality, which is why a co-worker recommended him, he is popular and therefore busy so that  maintenance visits are not usually available immediately.  However for the repair I needed during an outage, he was at my place very fast.  My generator's 'fail-to-start' happened before I bought the maintenance plan from RPS.  I figured I could do it myself, but it is not a small car engine in a box like I thought.  And now that we have medical equipment connected we need to make sure it is up and running 24x7.  Saving one fridge and freezer of food in a black out was sufficient payback for installing a generator, but keeping an oxygen pump running is critical, as is, I found, the piece of mind I get by going to sleep knowing my generator will start  everytime I need it, thanks to a proper maintenance plan.  Before I signed the maintenance contract, I did shop around some, and found that RPS adds things into their maintenance that others do not.  I asked Mike about it and he explained it to me very well, but I just can't remember the technical details.  I also found out that RPS is not as big as some companies, but to me this means I'm not getting some partly trained kid who is just rushing from job to job as fast as possible. From watching Mike work I can see that he is not only extremely knowledgeable (he mentioned something about certifications), but that he is methodical and thorough.  Those last two words describe RPS well.  And that's what I want in generator service while our life depends on it.

Generator Install questions, answered by experts

As a safety measure, you should always turn off the main breaker while operating your generator’s backup breaker. In addition, you should also switch off all appliance breakers so you don't have a power surge when the main breaker turns back on. And finally, turning off the main breaker prevents back-feeding, which endangers utility workers with the risk of electrocution. Back-feeding could also destroy the electrical circuits of your neighbors if they use the same power network.

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. 

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.

To determine the right size generator for your house, you should calculate the total wattage of the appliances and devices you want to power during an outage. List all essential items, note their start-up wattages, and add them together.

Here are some typical wattage requirements for common appliances:

  • Refrigerator: 600 watts

  • Large dehumidifier: 700 watts

  • Large window air conditioner: 1,400 watts

  • Water heater: 3,000 to 4,500 watts

  • Electric furnace: 5,000 to 25,000 watts

A 7,500-watt generator might be sufficient for essentials like a refrigerator, freezer, well pump, and lighting circuits. However, for high-demand items like a water heater or furnace, a whole-home generator is a better choice. A portable generator may be enough if you only need to power a few critical items.

While home square footage can offer a rough estimate, it is not always a reliable indicator. For reference, here are some typical generator sizes based on square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14 kW

  • 2,500 sq ft: 12–16 kW

  • 3,000 sq ft: 16–20 kW+

For the most accurate sizing, consult a professional who can calculate your home's peak and average power consumption and recommend the optimal generator.

You may need a permit for a portable generator if you’ll be installing a transfer switch for your primary residence or similar work. Otherwise, a permit for other uses may not be necessary. Check your local building codes or ask a local generator installer for more information about your local regulations.
