Lowest Price Guarantee
 Our Price Guarantee is our promise to you that you cannot find a comparable installation package for less...or we’ll pay you a $55.00 bonus over the difference.  All we request is that it be a valid, current and written “apples-to-apples” comparison.
24 Hour Fix It or Hotel Compensation
 In the unlikely event that your system has a problem, we guarantee that we will have your system working again within 24 hours of our arrival or we will let you decide if you would prefer hotel compensation for the night, or a cash compensation.
*'No Lemon’ Guarantee
 If the compressor in your Air Conditioner fails during the lifetime of ownership, or the heat exchanger in your furnace cracks during the lifetime of ownership, we will remove the entire unit, rather than just the component, and install a completely new unit.
Comfort Guarantee
 We guarantee that when properly designed systems are installed, maintained and operated in accordance with the manufacturer’s operating and maintenance manuals, your system will perform as we have agreed upon.  If the desired comfort is not achieved, we will make any repairs needed to your desired temperature at no charge to you for a period of 3 years.  Our Efficiency & Safety Agreement make it easy for you to have a worry-free system.
