Our Guarantee

Your complete satisfaction with our air conditioning and heating services and technicians is 100% guaranteed. Our on-time guarantee is one of the best in the country, and it’s backed by air and heating technicians that are trained, skilled and experienced to exceed your expectations and needs. You will never be kept waiting – “Always on time…or you don’t pay a dime.” ®

Total Comfort Guarantee

We want you to be comfortable, so that’s why we guarantee that the systems we have installed in your home will heat or cool your home to a custom design specification for a full five years.

We guarantee a temperature variance of no more than plus or minus three degrees of the design specifications of your thermostat, whether heating or cooling your home.

If the desired temperature selection is not achieved, we will make any modifications, repairs, and if necessary, replace the system at no additional charge to you.

100% Satisfaction Guarantee

On Time, Every Time

The One Hour part of our name means that we promise you, our client, that we will arrive at your home within the scheduled time window. If our HVAC technician does not show up at your home on time, you do not pay for the service.


If you are not 100% satisfied with the service we have provided, we will refund all of your money. If our technicians smoke or swear in your home, are not drug-free, do not wear shoe covers or they leave your home without cleaning up, you do not pay for the service.


We guarantee that repairs on your equipment are fixed right or the repair is free. If a repair fails during the season, we will repair it again, absolutely free.

We guarantee that the equipment we have installed will perform as we have stated. If the system does not heat or cool your home to your satisfaction, we will remove it and return 100% of your investment.
