Air Conditioner Types
Heat Pump Types
In the Murfreesboro and Middle Tennessee area, there are certainly plenty of houses with heat pump units and there’s a very good reason why. Although gas does heat an environment faster than anything, it also uses the most energy. Because Tennessee doesn’t have a lot of heavy winters, an electric heat pump is a great alternative because it can provide just enough heat to keep you satisfied most of the year. Like a refrigerator, heat pumps use electricity to remove heat from a cool environment and send it to a warm one, making the cool space cooler and the warm space warmer. During the heating season, a heat pump extracts heat from the colder outside air and sends it into the building. During the cooling season, heat pumps extract heat from inside the building and then sends it outside the building. Because they exchange heat rather than generate heat, heat pumps can provide much more energy than they consume. If you are needing a new heat pump system installed, we have a great selection of 14-seer, 15-seer, 16-seer, 18-seer, 20 seer and 23-seer heat pumps that will be efficient, quiet, and reliable for years to come.
Air-source heat pumps are the most popular because of their lower cost. They transfer heat between the conditioned space and the outside air. Heat pumps do an excellent job of heating and cooling between 45 and 95 degrees. High efficiency systems with a variable speed are even better because they can help dehumidify your environment which in turn makes your body feel cooler. When a person’s body feels cooler, they generally set their thermostat temperature to a warmer setting thus reducing the system’s run time and their overall electric bill. The efficiency of most air-source heat pumps will drop as the outdoor temperature continues to drop. Whenever you anticipate extended periods of temperatures’ below 5 degrees, we recommend considering a secondary form of heat such as a space heater or a wood stove. For homes that don’t have space to add ductwork, air-source heat pumps are also available in a ductless version also known as a ductless mini-split heat pump. See below for information about Ductless mini-splits.
Back up heat strips are normally added onto the air handler of the installed heat pump as a secondary form of heat. This helps to ensure that your home stays relatively warm when the outside temperature drops below freezing.
Heat Pumps aren’t like Furnaces!
If you are not familiar with heat pumps, you may find a few things odd about their functionality. Many people from northern states are often caught off guard by the condenser running during the winter season because up north condensers only run during the spring and summer. Here are a few other things may cause them to think their system isn’t working properly…
- Air coming from the vents isn’t hot
- Frost is on the side of the condenser
- Excessive puddles of water are around the base of the condenser
- Steam is coming from the top of the condenser
- The outside fan isn’t moving on the condenser
- There is a deep humming noise or loud pressure noise coming from the condenser
These things may appear to be strange, but they are all symptoms of normal operation during the winter season.
Gas units have 2 endearing qualities that people really rave about. First is that they can heat up a living environment in no time. You can’t say the same for an electric system. Gas units put off a lot more BTU’s of heat, which is basically the amount of energy needed to heat up one pound of water. In most cases, gas units will carry at least 30,000 BTU’s of heat more than same size heat pumps. Another thing people love is that they are generally more reliable. Heat pumps have lots more electrical components that can malfunction such as a reversal valve or defrost control board. Since heat pumps require the use of refrigerant year-round, they are more likely to break down or have a refrigerant leak. Selecting the right unit for your home or place of business really depends on you and what you’re looking for in a unit. The one downside to having a gas furnace is that it tends to make your living environment very dry. Sometimes adding a humidifier onto the supply side of your ductwork can help increase your humidity levels if you are worried about your skin drying out or the wood on your floor or cabinets getting too dry. Whatever your needs end up being, we have a great selection of 14, 15, and 16 seer gas units that will help keep you comfortable for years to come. Variable speed and two stage gas furnaces are both efficiency upgrades that you can get with split and gas package systems.
Ductless mini split
Mini Split Heat pumps offer an energy-efficient alternative to boilers, furnaces and air conditioners. Some models provide cooling and others can provide heating and cooling. All the mini-split products that we carry are super-efficient, energy star rated, and extremely reliable. One of the biggest selling points is that both the indoor and outdoor units are nearly undetectable to the human ear. If you are building a new high efficiency home, a bonus room or a build out, a ductless mini-split heat pump may be the perfect, cost effective, environmentally friendly, heating and cooling option you can get.
Dual Fuel Units - Split and Package Units
If you are a Tennessee resident and you want the best of both worlds, a dual fuel heat pump is probably the best way to go. Dual fuel heat pumps are a type of air source heat pump that works in combination with a gas furnace system. One of the advantages of this type of system is that the forced air furnace may be fueled with propane or natural gas. Because there are two sources of fuel being used for heating, this type of heat pump is not only efficient but also cost effective. You can get the efficiency benefits of running the heat pump on those mild winter days, and the comfort benefits of running gas when the temperature drops into freezing.
