"I'd been a customer of Excellent Air for over 10 years and during that time they had been reasonably priced and competent. However, in 2019 I noticed that the upper level of my home (I have a 3-zone system) was not cooling properly. They refused to address the issue and instead blamed the Nest thermostat I'd installed myself. It seems that if you install anything on your own, they're not interested in addressing issues. This issue went on for a year and when I expressed frustration with the situation, they basically said they didn't want me as a customer any more. I hired another HVAC company (JJB Mechanical) and they were quickly able to determine that the problem was a broken damper on the upstairs zone. What really irks me is that the guy from Excellent Air noticed that the cover for that damper motor was loose, so he just reattached it rather than actually checking the motor itself. So, I chalk it up to either laziness or incompetence. The bottom line is that for over a decade Excellent Air provided me with quality service. But to drop me as a customer over something that they should have been able to easily detect and fix speaks very poorly of either their newer technicians or corporate policy."

Generator Install questions, answered by experts

It might seem counterintuitive, but installing a generator transfer switch will save you money in the long run. While you’ll have to pay between $400 and $2,500 to have the transfer switch installed, you’ll recoup that amount later on when you don’t have to pay for expensive repairs to your appliances, devices, and electrical system that may have burned out, overloaded, or stopped working due to a sudden loss of power or an incorrect hook up of a generator to your home. 

Energy output depends on turbine size, average wind speed at your site, and system efficiency. A 5 kW turbine in a good wind location can generate 8,000 to 12,000 kilowatt-hours per year, which may cover a large portion of an average home’s needs. Accurate output estimates require a professional wind assessment and a review of your household’s energy usage patterns.

Sizing a generator is a careful process that requires calculating the electrical load of your entire house. You have to take into account every device you want to use and their wattage requirements, plus the wattage needed to start them, and look for a generator that can safely run all that at around 80% capacity.

In more practical terms, a small home can run on a 10,000-watt generator (and if you only want to power a few key appliances, much less than that). A mid-sized home may need something between 15,000 and 22,000 watts. Larger homes require 25,000 watts or more. 

It is safe to run a generator continuously, but you must follow safety protocols to ensure personal and home safety. Read the manufacturer’s instructions for specific recommendations, but the general recommendation is to turn generators off overnight or when you’re away from the house. Overworked generators can pose a fire hazard and if your generator is not in a well-ventilated area, running it continuously could lead to carbon monoxide poisoning.

No, this is extremely dangerous, often illegal, and you should never attempt it. If you connect your generator to your home without a transfer switch, the generated power can backfeed, essentially flowing back into the utility lines. Backfeeding exposes a significant threat of fatalities or harm to you and utility personnel, in addition to jeopardizing the structural integrity of your home.
