"Alex was excellent. Installed a plug for a generator and interlock switch on panel. Also installed a couple outlets. Was very friendly and did a great job and is very reasonably priced. Will definitely use him again for all my electrical needs."

"I can not began to express how happy my hubby and I were with the service provided by Dan. He was very professional, timely, and cost effective. When he took our generator in for repair, he actually left a generator just in case the power went out again. This was greatly appreciated as we have a sump pump and were just getting over cleaning our basement due to power outage which caused the use of our sump pump"

"I called John from Ajax to inspect my furnace as it had been "red
tagged-do not use" by another company and I wanted another opinion from a
local provider.  He was very knowledgeable and professional on the
phone, and came on time.  He thoroughly inspected the furnace, and used a
camera scan to look at the heat exchange that had been diagnosed as
cracked by another H&C company.  He spent close to an hour with me,
told me that there was no crack (hurrah) and also gave other pointers on
what could improve furnace performance.  He did not try to sell me anything and did not charge me for the visit.  He also suggested that if I doubted his diagnosis of  no problem,  that I could call Consumers Energy and have them come out to verify. 
Am planning on having him improve some poorly installed duct work,  and will not hesitate to call Ajax for my heating and cooling needs as I have two furnaces and two air conditioners.

Generator Install questions, answered by experts

Many services include assembling the unit and securing it in the window. Confirm with your provider.

Natural gas generators are designed to run for extended periods of time, such as power outages during a natural disaster. Since there’s no limit to the supply of natural gas, they don’t need to stop for refills. However, generators do need maintenance, including pauses to check and add oil. Constantly running them will also cause a lot more wear and tear, leading to a shorter lifespan.

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.

You may need a permit for a portable generator if you’ll be installing a transfer switch for your primary residence or similar work. Otherwise, a permit for other uses may not be necessary. Check your local building codes or ask a local generator installer for more information about your local regulations.

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.
