What’s the Best Way to Heat and Cool a Home Efficiently?

What’s the best way to heat and cool a home? I know good windows and insulation are a must, but I’m still puzzled when it comes to heating/cooling systems. -Rob

Hi Rob,

There are a number of choices these days when it comes to heating and cooling your home. Standard air source heat pumps work well for warm to moderate climates, but they can become expensive to use for heat when the temperature drops below 35° F. That’s because they draw their heat from the air, causing backup electric heat strips to cut on for additional heat at lower temperatures. Heat pumps that use natural gas for supplemental heat or gas furnaces are a more efficient option in colder climates.

Since a geothermal heat pump uses the constant temperature of water pumped from a well as the medium of heat exchange, they work better at lower temperatures than air source heat pumps. While the initial cost of installation for a geothermal heat pump is more, it makes up the cost in energy saved in five to ten years.

In addition, the cost of installing an Energy Star approved geothermal heat pump is eligible for a 30% federal tax credit. Details are available on our website at Energy Efficiency Tax Credits for Homeowners.

While electricity is about the only game in town for air conditioning, you can reduce your cooling bill by turning up your thermostat and using the evaporative cooling effect of paddle fans during the hotter months.

A programmable thermostat is another way to make your existing HVAC system use less energy. Simply setting the control to turn the heat or air up when you’re home and down when you’re away can save up to 15% on your energy bill. Not bad for a DIY project that costs under $100!

Good luck with your project,

  1. We have a customer that lives at 8600 feet currently has a propane fired boiler to heat his home that is need of replacement
    Research shows that a 96% replacement boiler only performs at 65% at altitude according to the home owner.
    the home owner is thinking of switching from propain to electric boiler
    Can you shed some efficacy on this subject
    thank you mike

  2. I will be replacing my HVAC system any day (it’s 20 yrs old). It’s electric unit with heat pump. I personally hate heat pumps. The house never seems warm in the winter or cool in summer. I live in Savannah GA. Our summers can be brutal. Winters vary. I have gas line to the house. Also natural gas is deregulated in GA and electricity is not.

    Thanks for your help!

    I loved the hot water heater calculater which showed I would save 50% if I switched to gas.

  3. Thanks for sharing this article, Danny! I think it’s awesome that you’re sharing efficient ways to heat and cool homes. You mentioned some valuable advice: getting a programmable thermostat. When you’re not at home, it’s important NOT to running the air conditioning or heating because you don’t need it—it’s simple. However, something that people aren’t aware of: changing your air filters on your HVAC machine can also help improve your efficiency. If there is dirt or debris covering the filter, the air won’t be circulating as efficiently as it could. Keep that in mind!
