Planning a Billings Heat Pump Replacement: Sizing, Rebates, and Backup Heat Questions

Home | Blog | Published on October 26th, 2026

If you’re thinking about replacing your heating system with a heat pump, you’re probably wondering how well it will work during a Billings winter. You also want to know whether it can keep your home warm without raising your energy bills. Our team at Big Horn Heating & Cooling helps homeowners work through those questions before choosing equipment. Here’s what to know about a heat pump replacement.

Heat Pump Replacement Checklist

A heat pump can heat and cool your home, but the right installation depends on more than your home’s square footage. Here are some questions to bring up during your consultation:

Is the Heat Pump the Right Size for My Home?

A bigger heat pump isn’t always the better option for your home. If it’s too large or too small, you could end up with uneven temperatures, higher energy bills, or unnecessary wear on the equipment. Ask our team to calculate how much heating your home needs.

How Well Will It Heat My Home in Freezing Temperatures?

Billings winters can get brutally cold, and some heat pumps struggle to keep up as temperatures drop. Ask your contractor how much heating the model can provide in extreme cold, since some heat pumps lose heating capacity as outdoor temperatures drop.

Cold-climate heat pumps are a great option for the local climate. They can operate efficiently even in below-zero temperatures. Another option is a dual-fuel system, which combines a heat pump with a backup furnace.

Will My Existing Ductwork Work with a New Heat Pump?

Your existing ductwork might work fine, but it should be checked before installing a new heat pump. Ask your contractor whether any ductwork repairs or adjustments should be included in the estimate.

Will I Need a Special Thermostat for My Heat Pump?

Some heat pumps need a specific thermostat to manage the heating, cooling, and backup heat in your home. Ask whether your current thermostat will work or if a new one should be included in the estimate.

Comparing Carrier Infinity Heat Pumps and Other Options

If you’re considering a Carrier Infinity heat pump, one of its biggest advantages is how it adjusts its output throughout the day instead of constantly turning on and off. This can help maintain more consistent indoor temperatures and reduce energy use compared to a traditional single-stage system. Ask our technicians to explain how an Infinity system compares with other models and whether the added features make sense for your home.
