Durham & Sons

Our guarantees

Promises are cheap. Ours are in writing.

Two guarantees back every installation we do, and both stay in force long after the truck leaves your driveway.

Guarantee one

Satisfaction Guarantee

Our installation technicians are the best in skill, attitude, and workmanship. They will care for your home, clean up when finished, and take personal responsibility for your satisfaction. If they have not performed in accordance with these high standards, we won’t consider the job done until you are satisfied with the results.

Guarantee two

Performance Guarantee

We have promised a maintained temperature variance of no more than 3 degrees from your selection to the actual temperature at your thermostat. If the installation temperatures are not achieved, we will make any necessary modifications, repairs, or replacements at no charge for a period of 2 years.

What 3 degrees means in practice

Set your thermostat to 74 and the room stays between 71 and 77, measured at the thermostat. If a system we installed cannot hold that line, every modification, repair, or replacement needed to get there is free for two years. No fine print that takes it back.

Put the guarantee to work.
