Cool Your Home Efficiently
Purchasing a new air conditioning system is a big investment, but you need to think more than just about the initial cost. Even though they can be more expensive to purchase, the cost difference for high-efficiency cooling equipment will be paid back over time through lower energy bills. If your central air conditioning unit is more than 12 years old, replacing it with a qualifying energy-efficiency system could cut your cooling costs by 30%. Plus, qualifying systems are eligible for a rebate from us - making it even easier for you to save money on your electricity costs.
Saint Peter Municipal Utilities provides rebates for qualifying central air conditioners, air-source heat pumps, and ground-source heat pumps.

Heating & Cooling System Performance Comparisons
Central Air Conditioners
Most homes use a central air conditioner system for cooling. When sized properly, a central air conditioner will cool and dehumidify a home to provide a comfortable environment during the summer months.
Central AC systems with higher seasonal energy efficiency ratings (SEER) are more efficient than standard models.
Air Source Heat Pumps
An air source heat pump cools and dehumidifies a home the same as a central air conditioner. The difference is that air source heat pumps have a reversing valve to allow the unit to also heat the home.
Air source heat pumps provide heating by capturing heat from the air outside the home and transferring it inside. It is less expensive to move heat than it is to create it like a furnace does, so moving this heat results in lower cost to heat your home.
Since air source heat pumps transfer the heat from outside air, they lose efficiency as the outdoor temperature drops. At an outdoor temperature between 15-30°F, your furnace kicks in because there is not enough heat in the outside air to adequately heat your home.
Split systems and single package air source heat pumps deliver conditioned air using ductwork. Through-the-wall air source heat pumps are used when no ductwork is available.
Ground Source Heat Pumps
Ground source heat pumps are one of the most efficient ways to cool and heat a home. They do not create heat, but rather move heat from one place to another - making them much more efficient than conventional heating and cooling systems.
Also known as geothermal heat pumps or GeoExchange systems, they use a liquid circulated though a looped pipe buried in the ground to transfer heat to the home in the winter and from the home in the summer.
