"Typical sales pitch...lots of niceties but not much info about the water heater. Because we were not prepared to purchase one that day we didn't ask all the questions we should have. The Sales Tech presented three Rheem water heaters they carried varying in price from the mid $2,000 to high $4,000 based on the years of warranties for each. We chose one totaling $3, 180.00. We asked about a discount and he gave us 15% off because my husband is a Veteran. Upon us agreeing we needed to replace our water heater, the Tech had my husband sign an "agreement" on the Tech's notepad. He didn't give my husband a chance to read it and seemed rushed to get it back. My husband just initialed it. We didn't get a written sales receipt nor a copy of the agreement form. We were told he'd email it to us the following morning. Meantime another tech installed the water heater. It wasn't until the following morning when we got the email with the Invoice that we noticed a couple of things: 1. Someone else had signed my husband's name on the second page of the Invoice. His initials were on the first page. 2. There was a charge for a 1 year TCC in the amount of $299.00. We had no idea what this was for. Then I checked online for the reviews on the water heaters and discovered that the Rheem Pro that Lion Home Service charged us $2,608.65 was priced for $986.19 at Walmart! Exact same model. The Thermal Portable water expansion tank that LHS charged us $272.85 for was priced for $57.84 on e-bay. It was the only company that carried that exact model. Upset that the company clearly took advantage of my husband and myself who are in our mid and late 70's, I messaged the company and told them as much. I got a response from Mr. Robert Blake, Tech Project Manager who tried his best to rationalize the extraordinarily marked-up price. He kept insisting it was not the same model. I have photos that say otherwise. The first Tech, Garrett Shryock called and apologized to me saying he was sorry he hadn't explained the $299.00 he had added to the invoice. It seems they charged us this so they could "give" us the 15% discount. Something about joining something for 1 year, with the first year being free! Nothing was thoroughly explained and some of this was our fault for not asking more questions. But the fact that the company inflated the prices so much, forged my husband's signature of the Customer Authorization, and added the $299.00 for something we didn't agree upon is indefensible. I checked out their FB page and there are several former customers who expressed similar complaints of overpricing their products, in some cases triple what they are elsewhere. They are willfully taking advantage of customers. I am an older adult who had a 26 year career in Social Services working with at-risk adults who have been exploited financially. Colorado states there are laws (CRS-18-6.5-103-Colorado Elder Abuse Laws), one, specifically addressing Exploitation: 2.7. : Penalties for exploiting an elder in Colorado depend on the value of the property exploited or the advantage taken. If the value is $500 or more, the penalty for Colorado exploitation of of a senior is: 4-12 years in prison, and A fine of $3,000-$750,000. We purchased this in good faith and expected honesty and integrity and we got neither. When I asked for an adjustment to the price, saying we would gladly pay for the unit at the cost I found it at Walmart and e-bay I was told "Absolutely not". They got our money so they don't care about the service or customer satisfaction."

Generator installations FAQs

Installing a whole-house generator costs about $5,000 on average. Prices range from $1,550 to $8,500, depending on size, brand, fuel type, and assembly. The size of your whole-house generator is the most significant cost factor, with large homes with high energy demands costing the most to power. Types of whole-home generators include:

  • Portable generators with 1kW–7.5kW capacity: $500–$2,000

  • Partial generators with 9kW–20kW capacity: $2,000–$6,300

  • Whole-house generators with 22kW–48kW: $5,000–$18,000

When maintained properly, a whole-house generator can last up to 20 years. Costs to maintain and repair generators vary by location and type of generator, but you can expect to pay about $150 to $300 per year for annual generator maintenance checks. An experienced generator service technician will inspect your generator’s engine filter, starting mechanism, fuel, lubrication, and coolant levels to keep your generator in good working condition for as long as possible.

When choosing the right size generator for your needs, consider a few items to help calculate the wattage you’ll need. Start by determining which household items and appliances you want to power, and then add the wattages together. Check out the wattage of these essential appliances:

  • Refrigerator: 600 watts

  • Large dehumidifier: 700 watts

  • Large window air conditioner: 1,400 watts

  • Water heater: 3,000 watts

Running home appliances like these requires a partial or whole-house generator. A portable generator may be enough to power your home if you only plan to keep a refrigerator and freezer running. 

Here’s what you can run with different wattages and types of generators:

Portable generator:

  • 2,000 watts can handle a large appliance like a freezer or refrigerator, plus a few smaller items like phones or computer chargers. 

  • 4,000 watts will keep two large appliances operating and a few smaller devices.

  • 8,000 watts should power most essential appliances and other devices, including a sump pump, well pump, or your dishwasher.

Partial to whole-house generator:

  • 20,000 watts and above will make it seem like your home’s power is still on.

The value of installing a whole-house generator is that your home has guaranteed power, even if the power grid in your area is down. Whether a whole-house generator is worth installing in your home depends on how often you use it, your home’s location, and your lifestyle. For example, installing a whole-house generator is likely worth it if you:

  • Experience frequent or prolonged power outages

  • Work from home

  • Store a lot of cold food

  • Have a sump pump

  • Have a pump for well water

  • Use electronic medical devices

  • Live in a climate requiring heating or cooling
