"Within minutes after submitting an inquiry, Seamus contacted me to find out specifics of my project and although he provided an estimate, he was receptive to coming out for a site visit before I committed. Edward came for the preliminary site visit and afterwards, I accepted their proposal. Cliff, the installer, communicated with me with scheduling and was very professional and easy deal with. Edward performed an inspection after install to make sure everything was done properly. The people representing this company seem very knowledgeable about their work and is backed up by generations of experience."

"Gentleman who owns Solarize was professional and courteous. He communicated well with the manufacturer and convinced them that a replacement inverter was needed based on the data he saw and the manufacturer had seen. It's what we were hoping for."

"We have had a hard time getting our Nest Video Doorbell installed because of the chimes that came with our house. After installing the proper transformer we could not get the Nest to work. I reached out to Home Advisor and HC Design was on the list of companies to contact. Before I could reach out a few companies reached out to me by leaving messages. What set HC Design apart from the others is Cornell not only called but sent me a text message after 11pm which told me he is really about getting the job done. I responded at 11:45 pm and he texted me back after midnight saying he could get our doorbell in later that day. I was definitely sold on Cornell and HC Design. The price was right! Mark showed up, immediately identified the issue, proceeded to install the doorbell and all within 45 minutes. Mark is friendly, knowledgeable, professional and just a really nice guy. Cornell followed up with a phone call since he was unable to make it due to being delayed at another job. I am definitely going to hire HC Design again for a couple other jobs we need done. Thank you for making this a pleasant and successful experience!"

Generator Install questions, answered by experts

While diesel is relatively stable, it won’t last nearly as long as propane and you may have to replace it if it sits unused for too long. Diesel can sometimes struggle to work efficiently or start engines during especially cold weather, so it’s not the best choice for every climate. Compared to fuels like propane and natural gas, diesel generators tend to be noisier and create more exhaust, which isn’t always ideal for home use.

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. 

With proper maintenance, a whole-house generator can last between 20 and 40 years. The specific lifespan depends on how often and for how long the generator is used, and some models may have their life expectancy rated in hours of operation. To maximize its lifespan, expect to spend around $150 to $300 per year for annual maintenance checks from a qualified technician. During these checks, a technician will inspect the engine filter, starting mechanism, fuel, lubrication, and coolant levels. Consulting your installer and choosing a low-impact fuel like natural gas or diesel can also help ensure your generator lasts as long as possible.

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.

If you’re deciding between a solar battery versus a generator for the best backup power solution, you can take a few factors into consideration. Solar batteries are quiet while generators can be quite loud. Generators have a lower up-front cost, but they require fuel and ongoing maintenance while solar batteries are more expensive but don’t have many ongoing costs.
