We Guarantee the Right HVAC System Size

For new system installations, our technicians will come to your home or business in order to take into account all of the important factors of selecting a new system. We perform a comprehensive Manual J Load Calculation on every consultation so that we can guarantee that your new system won’t be too large, nor will it be too small. You’ll get a proper, efficient system when you work with AIS!

Energy Savings Guarantee

Through our energy audit services and for new system installs, AIS HVAC contractors provide a quote letting you know what you can expect in terms of energy savings long-term. If our quote fails you, we pay you double the difference for a full year.

Our One Year Test Drive

Should your heating and cooling system fail to meet your expectations, and if we cannot do anything to solve the source of your dissatisfaction, we will remove the system and provide a full 100% refund on the cost of your investment at Any time in your first year of ownership.
