Frequently Asked Questions

You will find answers to most common Residential Backup Generators related questions.

Residential generator sizing is based on many factors such as size of home, number and size of Air Conditioning Units as well as number and type of appliances.

It is wise to slightly oversize the generator as it will allow the unit to serve all your backup power needs with minimal effort; doing so allows the unit to operate at a reduced RPM prolonging its life-span.

Most commonly installed Generator and probably the 90% solution for most homeowners seeking a whole house backup unit is the 20-22kW Air Cooled, WiFi-Enabled Standby Generator. It is capable of running a household with up to 7 tons of Air Conditioning Units.

A 20-22kW Air Cooled Generator on average will consume about 3Gallon/Per Hour. If running 24hrs a day, the consumption will average about 70 to 75 Gallons Per Day.

Tank selection should be based on the following criteria:

  • Tank Size (Fuel Capacity)
  • Homeowner Comfort Level of Generator runtime BEFORE running out of Fuel
  • Home Lot Size (Setback Restrictions)
  • HOA Restrictions (Placement Location, Above vs. Below Ground)
  • Environmental / Emergency / Situational Factors (Prolonged Weather Conditions, Blocked Roads, Closed Roads, Overwhelming Customer Call Volume)
  • Fuel Monitoring Device (Guarantees Homeowner Priority and Timely Propane Fills)


Available Tank Sizes
All Propane Storage Vessels are sized by Water Gallons, NOT Propane Gallons. Propane is 80% Liquid and 20% Vapor. This means that only 80% of the Water Gallon content can be occupied by Propane. 20% of any Storage Vessel’s content is reserved for Propane vapor. A Storage Vessel identified as a “120” means 120 Water Gallons so only 100 Gallons (80%) of Propane may occupy its space. A Storage Vessel identified as a “250” means 250 Water Gallons so only 200 Gallons (80%) may occupy its space. A “500” fits 400 Gallons (80%) of Propane and so on.

2 Type Category Tanks are available for the Homeowner

  1. DOT
  2. ASME

DOT [Department of Transportation]
  • Only available as a Vertical Tank
  • May NOT be buried. Above Ground ONLY
  • May be relocated and transported
  • Identified by #(Lbs) rather than Gallons (20#, 30#, 40#, 100#, 200#, 420#)
  • Limited to 420#(100Gallons)
  • Has a 12 Year Lifespan from New until Recertification is necessary

ASME [American Society of Mechanical Engineers]
  • Available in Vertical as well as Horizontal Configurations
  • Above or Below Ground
  • May NOT be relocated or transported
  • Identified by Gallons (120, 250, 500, 1000)
  • Has no Expiration Date

This question is very open-ended and is therefore best summed up in a ballpark figure.

The below cost breakdown is based on below criteria.

  • 20-22kW Generator with Battery and 200amp Transfer Switch & Storm Pad $5200 - $5500
  • Electrical Services (Simple to Very Complex Integration of Transfer Switch) $2000 - $4500
  • Gas Services (NG vs LP, Size LP Tank, Length of Gas Lines, Underground vs. Attic, etc.) $900 – $6000+


  • Most residential homeowners should budget $10,000 to $15,000 for an average Air Cooled Standby Whole House Generator project.

This endeavor start to finish has been completed in as little as 3 weeks. The average is 4 to 6 weeks provided County/City permitting, the weather and the Generator supply chain are all cooperative.

We think so and so do all of our customers. We are the only Turn-Key facility in Central Florida that meets all of its customers’ needs as a sole source contractor from the very first time we meet to long after the installation has been satisfactorily completed.

You will never get a runaround or be redirected to a sub-contractor to deal with whatever issue you are calling us about. Our commitment to you is that we are the first and final call you will make.

100%. Yes. Absolutely. You would do yourself a great injustice if you were to not do your homework.
Our mantra is “Call Everybody Else First, Then Call Us”. All residential generator Installation contractors are NOT the same.

You will find that the Turn-Key Value we offer far exceeds that which you may have been led to believe is the norm.

Reviews, reviews, reviews. Prior customers’ reviews of completed projects give you a glimpse of what you are getting yourself into. Do keep in mind that there are customers that can’t ever be satisfied no matter what. If you come across 5-star rated companies with 1 or 2 disgruntled customers, you might want to give the company the benefit of doubt. Companies with dozens of 1 star rating should trigger concern. Customers are FAR MORE likely to provide a bad review than a great one. While Home Advisor, Angie’s List, Lowe’s or Home Depot screen for qualifications, they can not be expected to ensure customer service or guaranteed satisfaction. It is the customer that ultimately is the final authority.

  • Apples to Apples Comparison – Electrical Installation is NOT Turn-Key; don’t forget Gas Installation, Fueling, Monitoring, Service & Maintenance
  • Teaser Rates (i.e. First Time Propane Fill Rates)

Most Residential Generator Warranties come with a “Limited” Warranty. The coverage ranges widely and is specific to each manufacturer. Parts and Labor is limited to a portion of the Multi-Year Warranty and it is on the homeowner to assess the breakdown of each manufacturer’s Warranty Claims.

Reading through the Manufacturer’s Warranty, the phrase “must be serviced by a Certified Technician” is at the forefront. Most manufacturers recommend basic services such as Oil/Filter changes, Battery and Belt checks and various other service-related tasks in intervals of 6 months.

Considering the sizable investment and to avoid unnecessary complications with potential future Warranty Claims, we highly recommend Manufacturer Recommendations be followed.

We also offer finance options as well as propane refill services so you are never left in the dark.
