I am a family business and owner/operator ran. My wife takes all the business phone calls and schedules appointments for free bids on everything. My business is owner operated I do everything from bidding, billing, service work to labor.A special that is always available for Northwestern Energy customers is a furnace tune-up for $75 with a full $75 rebate from Northwestern. I offer full warranties on part and labor with new installations. I am now installing geothermal heating and cooling systerms, these pay for themselves in 4-6 years and will save a propane customer up to $3000 a year. All bids are free.I do offer financing and my billing policies are to simply bill when the job is completed.
