You want a system to run and to last. You can trust that's exactly what you'll get from everything we install.

DALCO Heating & Air Conditioning promises 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.

Trust that your system is operating exactly as your thermostat shows. We have promised a maintained temperature variance of no more than 3 degrees from your temperature selection to the actual temperature at your thermostat under normal operating conditions. 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.

Our promise is meant to ensure that the equipment we install is sized accurately for your 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.
