A Rough Budget
ESTIMATE Adding HomeGuide’s figures for a propane home: the $6,000–$11,000 installed range plus a $400–$1,800 tank and a $130–$500 cold kit gives roughly $6,530–$13,300 before any panel or meter work. That is our arithmetic, not a quote. Some of these items may already be in an installer’s base price.
Costs That Depend on Your House
- Gas meter or regulator upgrade by the utility
- Panel replacement if the existing one is full or outdated
- Trenching across a long yard or under a driveway
- HOA-required screening or landscaping
Getting Comparable Quotes
Give every installer the same list of must-run loads and ask each for the load calculation, model number, kW rating, transfer switch type and an itemized list of what’s included. Then compare line by line rather than by total.
Frequently Asked Questions
Why do two quotes for the same size differ so much?
Usually the transfer switch type, load management, the length of the gas and wire runs, and whether a meter or panel upgrade is included.
Do I need a maintenance plan?
Not required, but HomeGuide prices maintenance at $200–$650 a year, and some manufacturer warranties depend on documented service.
Are permit fees included?
Ask. HomeGuide lists permits at $80–$450. In Edmond the licensed contractor must pull the electrical permit.
