"My installer Samuel was top notch, very detailed, pleasant, answered all my questions. Excellent representative. The only problem I had was miscommunication on their end as I was told available payment options and Samuel was told another. Did not affect installation or quality of work at all."

"The seal on the bottom of my garage door had dry rotted. I hired someone to replace it. They bought the part but could not install it. We were expecting a lot of rain, so I needed it done as soon as possible. I called Mach 1 Mechanical. Jason came out the same day. He was very professional and courteous. Jason determined that the part I had was not the correct part. Since it would take time to get the correct part, Jason decided to modify the part I had. He successfully modified and installed the part. There has been zero water entering under the door. Jason went the extra mile and I could not be happier with the job he did. He did it at an excellent price. I would hire him again in a heartbeat."

Generator Install questions, answered by experts

Potential benefits of using a natural gas generator include reducing your carbon footprint, lower likelihood of carbon monoxide exposure, budget-friendly operating costs, and low-maintenance, continuous fuel supply. Some possible drawbacks, though, include higher initial installation costs, dependency on a natural gas supply, and installation complexity. Keep in mind that pros and cons will vary based on the type and brand of natural gas generator. 

A home that is 2,500 square feet will likely need a 20kW to 25kW generator. Consult your local generator installer to confirm the generator size needed to power your home before purchasing a new one. Be sure to consider how much power your necessary devices need to run.

As a safety measure, you should always turn off the main breaker while operating your generator’s backup breaker. In addition, you should also switch off all appliance breakers so you don't have a power surge when the main breaker turns back on. And finally, turning off the main breaker prevents back-feeding, which endangers utility workers with the risk of electrocution. Back-feeding could also destroy the electrical circuits of your neighbors if they use the same power network.

In many cases, yes. There are models called dual-fuel generators and fuel switches, but only between certain types of fuel. For example, with the right setup you can convert a generator from natural gas to propane. Some allow switching between diesel and gasoline. There are even tri-fuel generators available in some cases, which adds a large layer of security if you are worried about fuel availability in times of crisis. Always check your generator capabilities and manual instructions before trying to switch fuels. Some generators can use another fuel but may need a fuel conversion kit to prep them first.

To reduce AC startup power for a whole-house generator, install a soft start kit or hard start capacitor, which lowers the initial surge by gradually ramping up the compressor. Using a smart load manager can also help by staggering startup loads, preventing a system overload and future costly repairs.
