"Tony Peavy went above and beyond to find and repair the wiring in our home. I had no idea how bad it was when I bought my home until my brother started to replace lighting fixtures. Tony searched extensively until he found and repaired the wiring which was a wiring nightmare. They also fixed the outlets in my living room that didn't work. I highly recommend him to anyone! He does an outstanding job, is very nice, patient and great pricing. Cindy "

"The latest visit diagnosed a failed ignition valve which needed to be ordered and replaced. They arrived promptly, assessed, diagnosed and ordered the parts immediately. It only took a few days for the parts to arrive and they were able to schedule me in for the service call. The first technician was able to maintain the ignition valve until the new part was available, which was directly responsible for heating my home. The second technician installed the part and was able to assist me in some technical updates on the app and digital thermostats. I learned so much from Michael and appreciated his knowledge and patience. He also fixed a safety issue on the second level and adjusted the air flow for the system. The system sounds so much quieter. It was a warranty issue with no cost."

Generator Install questions, answered by experts

If your home already has a grinder pump and you’re still noticing issues (like frequently clogged toilets and sinks), it could be time to upgrade your grinder pump. Start by checking your existing horsepower. If there are four or fewer people living in your home, using a 1/2-horsepower grinder pump should be sufficient. Larger households should consider investing in a 1-horsepower grinder pump to maximize wastewater removal efforts.

A 1,500 square foot home will likely need a 15kW to 20kW generator. When deciding on whole-house generator size, add up the total wattage of the devices that you’d like to continue running during a power outage. That way, you can ensure you purchase a generator that can power your necessary appliances or medical equipment during an electrical emergency.

When installed and used correctly, generators are safe to use. The most critical generator safety tips to keep in mind are:

  • Never use a portable generator inside an enclosed space, as the carbon monoxide exhaust it creates is lethal.

  • Never attempt to connect your generator to your home’s electrical panel independently; hire a professional for this dangerous job.

  • Never overload your generator by connecting more appliances than for which it’s rated; you can damage your generator and appliances or even cause a fire.

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.

Whole-house generators can last 20 to 40 years with normal operation and proper maintenance. If you look up the specifications for your generator, you may be able to find a lifespan rated in hours of operation. Life expectancy will vary depending on how often and for how long you use the generator each year. Choosing a fuel with low impact like natural gas or diesel can help generators last as long as possible.
