Advanced Energy Concepts guarantees that when the equipment we have installed is maintained and operated in accordance with the manufacturer's operating and maintenance manuals, the system will perform as we have stated and agreed upon. If at any time during the first year of installation, your Heating system does not maintain 70 degrees at the thermostat location when the outside temperature is 0 degrees Fahrenheit or your Cooling system does not maintain 73 degrees at the thermostat location when the outside temperature is 98 degrees Fahrenheit, we will replace or adjust the system to meet these specifications or we will remove the system and refund your money. If the installation temperatures are not achieved, we will make any necessary modifications, repairs or replacements at no charge to you for a period of 5 years. This guarantee is meant to guarantee that the equipment we install is sized accurately for the home at the time of installation. It does not cover situations where the home does not maintain proper temperature caused by a component or part failure.
