"My experience with this company was not so great. We called them on a Thursday afternoon to come out and look at our furnace which was dripping water. I was thrilled when they said they could come out that same day. The tech arrived and diagnosed our issue very quickly, but the part had to be ordered so they would have to come back the next day to install it. The part was called a collector box and it basically is a large rectangular piece of plastic housing with a gasket that collects condensate. It was leaking from both bottom corners. He quoted us $800 to replace it. I thought that price was kind of steep, but whatever, sure go ahead and get our heat working. The part arrived the next day and the same tech from the previous day arrived shortly after to install. This is where things start to go downhill. After he gets it all buttoned up, he announces that the new collector box didn't come with an exterior gasket. He claimed he couldn't remove the old gasket from the old collector box because it was too deteriorated. The manufacturer doesn't sell the gasket separately, but he'd be willing to replace our perfectly functioning motor (which comes with a new gasket which is what we really needed) for the low low price of $1900 additional dollars. Better yet, he suggested we replace our whole furnace for somewhere in the neighborhood of $6000. He even offered us financing with a monthly payment plan! So an $800 repair has suddenly ballooned into $6000. Something didn't seem right so I did a quick Google search, found the schematic for our furnace, located the part number for the gasket and ordered it online. THE PART COST $6.00!! We advised the tech that we were not prepared to spend such a large sum of money and to please put the old collector box back on our furnace and leave. As it turns out, it was NOT the collector box that needed replacing. The box itself was in great condition. It was the INTERIOR gasket that had worn out and was leaking water. The EXTERIOR gasket that goes between the motor and the collector box did not even need replacing. However for 6 whole dollars plus shipping, we received both gaskets for our unit and our 8 year old furnace is working great now with no leaks. Also the motor that they quoted us $1900 to replace unnecessarily, only cost $125 on the same website brand new with the gasket. I understand there are labor costs involved with any repair, but Christ! And here's the kicker, it's been more than a week since this whole fiasco took place and they haven't refunded our money as of yet. Matter of fact, there was a new charge from them that appeared on our credit card statement today. May have to fight it through the credit card company, who knows. Our basement has constant video surveillance so this was all captured on video. Needless to say, we will not ever call this company again to repair anything and could not in good conscience recommend their service to anyone. Proceed at your own risk."

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
