Frequently Asked Questions


Frequently Asked Questions About Heat Pumps

  • 1. Do heat pumps really work in Minnesota winters?

    Yes — cold climate heat pumps are built for freezing temperatures and can efficiently heat homes even when it’s -25°F or colder

    New refrigerants and variable-speed technology make them reliable and cost-effective for Minnesota homes.

  • 2. What rebates or incentives are available for installing a heat pump in Minnesota?

    There are several rebates available:

    Up to $4,000 in state rebates (coming via the Inflation Reduction Act)

    Up to $2,000 in federal tax credits

    Local utility rebates between $675–$2,400 depending on your provider

    We’ll walk you through all available incentives and handle the paperwork.

  • 3. Can a heat pump replace my furnace completely?

    In many cases, yes. Cold climate heat pumps can serve as your main heating source. Some

    homeowners choose to pair them with a gas furnace in a dual-fuel setup for backup during extreme

    cold.

  • 4. What’s the difference between a mini-split and a standard heat pump?

    A mini-split is a ductless heat pump that heats and cools individual rooms. A standard (ducted)

    system connects to your existing HVAC ductwork. Both work well in Minnesota — it depends on your

    home’s layout and goals.

  • 5. Do heat pumps also provide air conditioning?

    Yes! All heat pumps provide both heating and cooling. In summer, they work like an air conditioner

    — pulling heat out of your home and keeping things cool and comfortable.

  • 6. How long does a heat pump last?

    On average, a quality heat pump lasts 15–20 years with proper maintenance. We recommend

    annual service to keep it running efficiently, especially with Minnesota’s seasonal extremes.

  • 7. What kind of maintenance does a heat pump need?

    Basic maintenance includes:

    • Checking air filters monthly
    • Clearing snow and debris from the outdoor unit
    • Annual professional inspection
    • We offer seasonal maintenance plans to keep your system in top shape.
  • 8. Can I install a heat pump if I don’t have ductwork?

    Absolutely. Ductless mini-split systems are perfect for homes without existing ductwork 

    or for adding heating/cooling to specific rooms, garages, or additions.

    We’re here to help you find the right comfort solution for your home.

  • 3. How often should I service my furnace or air conditioner in Minnesota?

    At Air Max Heating & Cooling, we recommend scheduling professional maintenance twice a

     year — once in the spring for your air conditioner and once in the fall for your furnace or heat pump. 

    Regular tune-ups help improve energy efficiency, prevent breakdowns, and extend your system’s

    lifespan — which is especially important in Minnesota’s extreme weather conditions.

  • 4. Why is my energy bill higher during the winter months?

    Cold Minnesota winters put extra demand on your heating system. However, if your bill is 

    unusually high, it may be due to clogged filters, air leaks, thermostat issues, or an 

    aging furnace. Our Air Max technicians can perform an energy efficiency inspection to 

    identify and fix the root cause, saving you money and improving comfort.

  • 5. How do I know if my furnace needs to be replaced?

    It may be time to replace your furnace if it’s over 15 years old, requires frequent repairs, or struggles 

    to keep your home evenly heated. You might also notice rising energy bills or strange noises. 

    Air Max can perform a system evaluation and recommend the most cost-effective replacement

     — including Trane furnaces designed for cold-weather performance.

  • 6. How long do furnaces and air conditioners last in Minnesota?

    With proper maintenance, most furnaces last 15–20 years, and air conditioners last 

    12–15 years. Minnesota’s cold climate can shorten these lifespans if units aren’t 

    serviced regularly. Air Max offers comprehensive maintenance plans to help your system

    last longer and run efficiently.

  • 7. Why does my furnace make loud noises when running?

    Unusual noises — like banging, rattling, or whistling — can indicate issues such as 

    loose components, dirty burners, or blower motor problems. It’s best to have an 

    Air Max technician inspect the system promptly to prevent further damage or 

    breakdowns.

  • 8. What size HVAC system do I need for my home?

    System size depends on your home’s square footage, insulation, windows, and layout. An oversized 

    or undersized unit will waste energy and reduce comfort. Air Max performs detailed load calculations

     to ensure your new system is perfectly sized for your home’s heating and cooling needs.

    Cold Springs,and surrounding areas. Whether your furnace stops on a freezing 

    night or your AC quits during a heatwave, call Air Max at (320) 496-9200 — our
