Will I Need a Furnace with a Heat Pump? It Depends

July 19, 2022

The concept of installing both a furnace and heat pump may sound a bit unusual at first. After all, why should you need two heating systems? Even though furnaces and heat pumps both produce energy-efficient heat, the variations in their design genuinely make using both of them a reasonable option. It’s not for all of us, but in the right conditions you will absolutely benefit from using a furnace and a heat pump.

You should weigh several factors in order to decide if this type of setup works for you. Your local climate and the dimensions of your home are both highly important, especially for the heat pump. This is because some models of heat pumps will function less efficiently in colder weather and larger homes. That being said, you can still take advantage of heat pump installation in Kingsville.

Heat Pumps Might Be Less Reliable in Winter Weather

Heat pumps are generally less efficient in cooler weather because of how they create climate control to begin with. Unlike furnaces, which burn fuel to provide heat, a heat pump reverses its flow of refrigerant to pull heat from outdoor air. This heat is then pulled inside and dispersed all through your home. Assuming there is still a little heat energy in the air, a heat pump can function. But the cooler the temperature, the less effective this process is.

The less heat energy is accessible outside, the longer it takes a heat pump to bring heat indoors to maintain your ideal temperature. It can depend on the type of make and model, but heat pumps generally start to lose efficiency at temperatures of 40 degrees and colder. They should still be an energy-efficient option until 20-25 degrees, at which a gas furnace is more effective.

What Temperatures Do Heat Pumps Perform Best In?

Heat pumps manage best in milder climates 40 degrees and up. That said, you don’t have to lose out on the benefits of a heat pump just because the local climate is colder. In fact, that’s why using both a furnace and heat pump can be worth the expense. You can keep the heat pump for energy-efficient heat until the weather is cold enough to justify shifting to something like a gas furnace.

A few makes and models feature greater performance in winter weather. For example, the Lennox MLA heat pump is capable of running at 100% capacity at 0°F. It can even continue running in temperatures as low as -22°F. For maximum energy efficiency, you’ll likely still want to swap to the furnace in particularly cold weather.

So Should I Put In a Heat Pump If I Use a Gas Furnace?

If you’re interested in maintaining the most energy-efficient HVAC system possible, owning a heat pump and gas furnace at the same time deserves the investment. Not only is a dual-heating system flexible, but it provides other benefits like:

  • A source of backup heating – A redundant heating system means even if one breaks down, you still have the capability to heat your home. It may not be the most energy efficient, but it’s better than shivering in an unheated home while you sit around for repairs
  • Fewer energy costs – The ability to decide which heating system you use based on the highest energy efficiency decreases your total costs. Smaller heating bills over the life span of these heating systems can really add up to plenty of savings
  • Less strain on both systems – Instead of running one system all winter long, heating resources are divided between the furnace and heat pump. Crucial parts can survive longer as they’re not under continuous use.

If you’re still hesitant about heat pump installation in Kingsville, don’t hesitate to reach out to your local certified technicians. They can evaluate your home’s comfort needs and help you decide if a dual-heating HVAC system is the better option.
