AC Replacement in Ham Lake, MN
Ham Lake homeowners replacing cooling have two main options with us: central AC at $5,200–$9,800 installed, or a heat pump at $7,500–$14,500, often the better fit on propane. Both come with a written flat-rate quote sized by Manual J and a 2-year labor warranty.
AC replacement calls in Ham Lake homes
On a Ham Lake property, the AC replacement question is often whether it should be an AC at all. For a house on propane, a heat pump cools the same way in summer and carries much of the heating in spring, fall and milder winter days, cutting propane use, with the furnace taking over in deep cold. Connexus Energy, the electric utility, lists rebates for air-source heat pumps and an AC rebate, so check its current rules, including whether it needs a registered contractor.
Placement takes more thought on big lots. The condenser should sit where roof snow and ice won't land on it, out of the drift zone, on a pad that stays level through frost, with the manufacturer's clearances on every side. Custom homes with the mechanical room far from a good condenser spot may need a long line set, and each manufacturer caps the length and lift, so we check those limits before settling on a location.

How much does a new central AC cost in Ham Lake?
A new central air conditioner from us runs about $5,200–$9,800 installed in Ham Lake, sized with a Manual J load calculation. Same prices in Ham Lake as in every town we serve. See the AC replacement cost guide or furnace and AC together.
Are there rebates for a new air conditioner in Ham Lake?
Ham Lake is on Connexus Energy for electricity, which matters most for propane homes. Connexus offers rebates on air-source, ductless and ground-source heat pumps and on central air, and a reduced-rate program for heat pumps paired with a furnace; ask whether the air-source rebate needs a registered contractor. Where natural gas is available, the supplier is CenterPoint Energy or Xcel Energy depending on the street. CenterPoint's furnace rebates work with any dealer, and Xcel runs its own heating equipment rebates. Rebate programs change every year, so check the utility's current terms before you buy.

AC replacement in Ham Lake: questions
Will a heat pump keep our Ham Lake house warm in January?
Not alone on the coldest nights, and it doesn't have to. Cold-climate heat pumps keep producing heat well below zero, and Mitsubishi rates its Hyper-Heat line to run down to -13°F, but capacity drops as it gets colder. Most Minnesota installs keep a backup, and in Ham Lake that's usually the propane furnace. The heat pump carries the mild and moderate days, which add up to much of the heating season.
Our Ham Lake house still has its original 1990s AC. Can we replace just the condenser?
No. The outdoor unit and the indoor coil are rated as a matched pair, and a 1990s system runs R-22, while equipment built from 2025 on uses R-454B or R-32. The coil on the furnace has to change with it, and the line set usually does too, since it carries old oil and may be the wrong size. We quote the matched system and tell you whether any part of the old setup can stay.
