"Installed a new furnace for us during the winter when we needed it the most. They were able to install it 2 days after we asked for them to service our old existing furnace in which they showed us why it needed to be replaced. Quick and clean instillation with two knowledgeable and friendly employees."

"I had an EXCELLENT experience with Comfort By Design (Hudson location) starting with Aaron who came out to give me a quote on replacing my Furnace/AC to the guys that installed it all. Aaron thoroughly explained all of my options and provided me an estimate right then and there.  He communicated with me very promptly on any questions I had when I was deciding what to get. Everything he said (quietness, quality, what was included in the price, etc) was exactly what he promised. The guys who installed it both knew what they were doing, were very professional and cleaned up everything as if they were never there. They also were there exactly when they said they would be.
Comfort by Design is very reasonable and left me feeling good knowing what I spent my money on!   My only regret is wasting time getting 3 other quotes.  STRONGLY RECOMMEND!!!

"They did an excellent job installing a new 240V outlet in my garage! We were able to easily schedule an appointment. They arrived to my house on time. As they were working they were extremely friendly and communicated proficiently. Once the project was finished everything looked great and the outlet works just fine. I would highly recommend for anyone needing a local electrician."

"These folks replaced my furnace and installed a central air conditioning system at the same time. The intial contact, work estimate, and scheduling was easy for me to do and the manner in which I was treated was first class professional and very courteous. The crew who did the work (Brant B., Brad, Melissa) was top notch, worked diligently, produced a high quality installation, and completed the work in seven hours. It was an amazingly good experience for me and I high recommend Air Mechanical!"

Generator Install questions, answered by experts

While the rating will tell you how many watts the refrigerator needs at the peak of its cycle, it requires additional wattage to start. At the bare minimum, you’ll need a 1,500-watt generator to get the fridge up and running after a blackout. A 2,000-watt generator should be sufficient for most home refrigerators.

Natural gas and electricity rates vary significantly based on location, and pricing can change over time, too. It’s possible that in locations where natural gas is particularly inexpensive, it will cost less than grid-based electricity will. However, you should also factor in the generator’s initial costs and maintenance needs, as well as its noise level and if it can comfortably power all your home appliances.

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. 

To power a central air system during a power outage, the whole-house generator will need to be at least 5,000 watts, and this number will significantly increase for larger units. Check the specific wattage requirements of your AC unit to choose the right generator size. Consider consulting a generator installer to ensure your whole-house generator meets your electrical load needs.

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.
