"I would highly recommend Garrett at Loos Electric, Inc! Garrett ran electric for our new above ground pool quickly and was able to work with us on a tight turnaround when our pool install was pushed up by a month and two days before we left for vacation. He was very professional and a pleasure to work with. We will definitely be reaching out to him for our future electric needs!"

"Marlock Electric upgraded our electric service from 100 amp to 200 amp. We were installing solar panels with our new roof, and did this upgrade along with that project. Marlock was recommended to us by the contractor installing the solar panels as a company that would do a very professional job for us - they wanted to be sure the work would be done right to connect the solar system to it. Marlock did an excellent job for us - it was somewhat complicated, but they are experts who knew how to do the work properly. They explained the whole process to us and answered all our questions in a way we could understand. They added extra crew members to make sure the work was done in one day so we wouldn't need to be without electric service overnight. The work was done in a very professional manner, and the site was cleaned up before they departed. We are very satisfied with the service we received from Marlock Electric, and will call on them for any future electrical work we need to have done."

"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.

"Mike and Neil did a great job installing a new 200 amp panel box, interlock generator switch, bathroom heater with timer switch, 6 outlets and a light switch. Best of all we purchased a one year membership that took 10% off the work we had done and will provide us the same discount for one year. We also used a mailer coupon for the panel box. In all our savings was about $1000."

Generator Install questions, answered by experts

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.

To reduce AC startup power for a whole-house generator, install a soft start kit or hard start capacitor, which lowers the initial surge by gradually ramping up the compressor. Using a smart load manager can also help by staggering startup loads, preventing a system overload and future costly repairs.

You can expect a diesel generator to last for up to 30,000 hours of use, which works out to 20 to 25 years with the proper maintenance, of course. That depends on how much you use it, so a diesel generator used for emergencies a couple of times a year will last a lot longer than a generator that takes over for a faulty electrical grid every month for a day or two. 

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

A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.
