We will size your system properly. An improperly sized geothermal system is the number one reason for dissatisfaction with a ground-source heat pump system. If the system is too big, you’re spending money on equipment you don’t need, and your system will be too loud, and will not control humidity properly. And if it’s too small, you won’t be comfortable on those hottest days of summer.

We prioritize the proper sizing and insulation of the ductwork your new heating and AC system utilizes. Jansen Heating, Air Conditioning & Electrical will be around, you can count on us with your seasonal maintenance.
