AC Installation & Replacement in Rosemount, MN
The right air conditioner for Minnesota isn't the biggest one — it's the one sized to wring the humidity out of a muggy August night without short-cycling. Groff Heating & Cooling installs Carrier systems matched to your home's actual load, with free estimates and financing available.
We've been replacing south-metro air conditioners since 1991, and most installs are done in a single day.
Why sizing matters more than tonnage
An oversized AC cools the air fast but shuts off before it dehumidifies — which is why some houses feel cold and clammy at the same time. We measure your home's real cooling load and recommend a size that handles both temperature and Minnesota humidity.
We'll also explain SEER2 efficiency ratings in dollars, not acronyms: what the higher-efficiency unit costs up front, and roughly what it gives back each summer on your electric bill.
What's included in your install
Removal and legal disposal of the old unit and refrigerant, a properly matched indoor coil, new pad and line set as needed, full commissioning with verified refrigerant charge and airflow, warranty registration, and a walkthrough before we go.
Replacing your furnace at the same time? A matched system often costs less than two separate projects — we'll quote it both ways in your free estimate.
Common Questions
- When is the best time to replace an AC?
- Spring and fall, when you're not depending on it daily and scheduling is flexible. If yours limps through August, get a free estimate in September rather than gambling on next June.
- How long does an AC install take?
- Most are done in one day. Combined furnace-and-AC replacements sometimes take two.
- Should I consider a heat pump instead?
- Worth a real look. A modern cold-climate heat pump cools exactly like an AC in summer and can also handle most of your heating season, with your furnace as backup. We quote both options on request.
