"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

Costs range from $500 to $2,500, depending on generator type and installation complexity.

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 can expect a diesel generator to last for up to 30,000 hours of use, which works out to 20 to 25 years with the proper maintenance, of course. That depends on how much you use it, so a diesel generator used for emergencies a couple of times a year will last a lot longer than a generator that takes over for a faulty electrical grid every month for a day or two. 

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.

Costs depend on generator type, labor, and additional wiring or transfer switch requirements.
