Deciding to Seek Help For Your AC Unit

By the time you finally get into bed at night, you might not want nothing more than to watch a fun television show in your cool, air conditioned master bedroom. Unfortunately, if you are experiencing trouble with your air conditioner, you might find yourself in a stuffy, uncomfortable space instead. However, air conditioning trouble doesn't have to come as a surprise. If you can learn to recognize the signs of trouble early, you might be able to call in the professionals before things turn sour. On my blog, you will be able to read through loads of helpful information on HVAC, so that you can detect trouble before it ruins your sleep.

Can Your Heat Pump Run on Entirely Renewable Energy?


If you're considering the purchase of a heat pump to replace your current HVAC system, one of your deciding factors may be the increased efficiency of these heating and cooling systems as compared to those that run on heating oil, propane, or compressed refrigerants. However, certain types of heat pumps can be made to run on entirely renewable energy sources -- essentially eliminating your monthly utility bills. Here is more about your low-cost and high-efficiency heat pump options.

What is a heat pump?

Heat pumps are a scaled-down version of a geothermal energy system -- for some, piping is run into an underground "heat sink," which is used to pump warm air into your home during the winter months. In the summer, when this underground air is cooler (like a cave), the heat pump funnels this cool air into your home, displacing the warmer above-ground air. This process requires some electricity to run the pumps, but is overall much cheaper and better for the environment than running both a heating and air conditioning unit.

Other heat pumps run on outside air, rather than geothermal air. These require a vapor-compression system, essentially operating as an air conditioner in reverse. Although these systems are also energy-efficient, they're not always as inexpensive as the geothermal systems.

Which types of heat pumps run on renewable energy?

As energy-efficient as most heat pumps are, they can be made even more efficient by running partially or entirely on renewable energy.

  • Air/water-brine/water heat pumps
    These pumps have two evaporators, as compared to the single evaporator found in most heat pumps. The outer evaporator runs on air, while the interior evaporator runs on a brine-water mixture. The presence of separate evaporators allows the heat pump to always choose its most efficient mode. In some situations, you can override this mode. For example, if your electricity charges increase during "peak hours," you can essentially eliminate these charges on your electric bill by programming the heat pump to run on geothermal energy during peak hours.
  • Hybrid heat pumps
    These pumps also run on twin evaporators, allowing increased efficiency -- however, one additional advantage of hybrid pumps is their ability to store the heat generated from the ground during hotter summer months. This stored heat can help keep your home warm during the fall and winter months, and in some cases may even eliminate the hybrid pump's need to rely on geothermal energy to heat your home in winter.
  • Geothermal heat pump
    Like other geothermal systems, these heat pumps operate entirely on heat and energy gained from the ground. These heat pumps are nearly three times more efficient than radiant electric heat, and -- after paying for installation -- you may enjoy significantly reduced utility bills.
