If you are dissatisfied with the performance of your new system within the first year, we’ll work to make it right with our money back guarantee.

We guarantee during the cooling season that your Gilley’s replacement system can maintain a temperature at least 25 degrees lower than the outside temperature at the thermostat during its first year of operation.

*Note: when temperatures increase to 100+ degrees, this reduces your cooling capacity and increases your energy usage. Sometimes you will have to run your unit 24 hours a day to maintain desired indoor temperatures during extreme heat.

All guarantees subject to terms and conditions. Click Here to read.
