Air conditioning used to feel optional in Anchorage. These days, more homeowners are looking for reliable cooling when summer temperatures climb. That brings up an important question: Should you install a traditional AC system or choose a heat pump instead?
Both can keep your home cool. The biggest difference is that an AC system only cools, while a heat pump can both cool and heat your home. For Anchorage homeowners, that extra heating capability can make a heat pump especially worth considering.
First, How Does a Heat Pump Work?
During the summer, a heat pump works much like a traditional air conditioner. It pulls heat from inside your home and moves it outdoors. When temperatures drop, the process reverses. The heat pump collects available heat from the outdoor air and transfers it inside. That makes a heat pump a two-in-one HVAC system rather than equipment dedicated only to cooling.
Modern cold-climate heat pumps have also come a long way. ENERGY STAR’s cold-climate criteria require qualifying systems to demonstrate heating performance at 5°F, including a coefficient of performance of at least 1.75 at that temperature.
Why Heat Pumps Make Sense in Anchorage
Anchorage doesn’t have the cooling demands of Phoenix or Atlanta, but that doesn’t mean summer heat can’t make a home uncomfortable. National Weather Service climate normals put typical late-July highs around 66°F, and Anchorage has experienced significantly hotter temperatures, including the city’s record 90°F day in July 2019.
If you’re already investing in Residential HVAC equipment for summer cooling, choosing a heat pump gives you another benefit for the rest of the year.
During milder fall and spring weather, a cold-climate heat pump may be able to heat your Anchorage home efficiently without relying as heavily on your primary heating equipment. The U.S. Department of Energy notes that cold-climate heat pumps are specifically designed to maintain better capacity and efficiency at temperatures below freezing.
DOE research has also found that cold-climate air-source heat pumps can reduce household energy consumption by up to 40% in certain homes, with potential savings depending heavily on the heating system they’re replacing and local energy costs.
Does That Mean You Can Get Rid of Your Furnace or Boiler?
Not necessarily. Anchorage winters are very different from winters in many parts of the Lower 48. As temperatures fall, every air-source heat pump loses some heating capacity and energy efficiency.
For that reason, many Alaska homes may benefit from a dual-system approach: use the heat pump when conditions are favorable and keep a furnace, boiler, or another properly designed heating source available during the coldest weather. The Cold Climate Housing Research Center has similarly emphasized the importance of backup heating when air-source heat pumps are used in Alaska’s colder conditions.
When Does Traditional AC Make More Sense?
A standard AC system can still be a perfectly good choice if your only goal is cooling. For example, traditional AC may make sense if:
- Your existing furnace or boiler is relatively new and efficient.
- You have no interest in using electricity for supplemental heating.
- You’re looking for a simpler cooling-only upgrade.
- The layout or electrical system in your home makes a heat pump less practical.
Ultimately, there isn’t one answer that fits every house. Best to get a free consultation to see if your home really needs an AC system if you live in Anchorage.
So, Which Is Better for Your Anchorage Home?
If you’re installing cooling from scratch, a heat pump is worth a serious look. You get the summer comfort of an AC system plus the ability to provide efficient heating during portions of Anchorage’s long heating season. But equipment selection matters. A system that’s great for a mild coastal climate isn’t automatically right for Alaska.
At Diamond Heating & AirTemp Alaska, we can look at your current HVAC system, your home’s layout, existing heating equipment, electrical capacity, and comfort goals to determine which option makes the most sense.
