If set to "auto", the fan operates only when the temperature requires it. This is the most efficient setting. However, there are advantages to using the "on" setting. Air is constantly filtered through the unit's filter, and the constantly circulating air results in a more even temperature throughout the house.

Yes, using a propane conversion kit.

Depending on fuel prices, a gas furnace is about 40% less expensive.

Gas is cleaner, more efficient, and less expensive (up to 50%).

It warms more gently, only using the higher stages when needed.

Variable speed "smart fans" are very quiet, and can alter air flow based on the needs of your home, creating more even temperatures and increased comfort. They also allow for constant airflow, providing increased filtration of the air in your home with low overall energy consumption.

No. Great strides have been made in increasing the reliability of 90% furnaces. If you purchase a quality furnace AND it is installed correctly, you shouldn’t see any difference between the life of an 80% and 90% furnace.

Heat pump equipment in the heating mode is rated by the Heating Seasonal Performance Factor or HSPF; the higher the HSPF rating, the more efficient the unit. The minimum rating for Energy Star compliance is 8.2 HSPF. The highest efficiency heat pumps will meet or exceed 9 HSPF.

That depends on the size of the blower fan in your existing furnace, the capacity of your duct system, and the cooling needs of your home. Our consultants can inform you of your options, along with the cost and benefits of each.

220 volts. If you do not have this service available, we can arrange for an electrician to install it.

Air conditioners work by transferring heat from inside your home to outside, effectively lowering the indoor temperature. Heat pumps work exactly the same way in the summer, but in the winter they can reverse the temperature exchange, providing one of the most efficient forms of heat available.

Heat pumps heat more gently and evenly than furnaces, so if you’re used to a blast of hot air from your vents, you’ll have to get used to the new type of heat. They are, however, one of the most efficient forms of heat available, and work best when you set them to maintain a constant indoor temperature.

Yes and No. It depends on the pump and the system. Heat pumps gradually lose efficiency as the temperature drops. They typically need some help to heat your home depending on its’ system rating to the outdoor temperature. Consult an experienced PlumbLine technician to evaluate your heat pump.

Locate your outdoor AC unit (see our products page if you are unsure what it looks like), and check to make sure that it is running when your thermostat calls for cooling. If it is not running, or if it is running but is not cooling your home, turn it off at the thermostat and have it inspected by a qualified technician immediately.

Generally, you should set your thermostat where you feel comfortable. But we recommend keeping your thermostat at 73 degrees or higher in the summer. Lowering your thermostat below 73 can cause your indoor coil to freeze up, leaving you stuck without any AC until it thaws!

Yes. It provides instant hot water however you must have a recirculation pump on your water heater. When properly sized and installed, a tankless water heater will provide endless hot water, so cold showers will be a thing of the past. They can also save energy costs by eliminating the need to heat stored water.

That depends on the type of system you want, the size of the system required, and the condition of the work area, ductwork, and other factors affecting the installation. We can give you an exact price after a consultation with one of our experts.

No. PlumbLine stands behind every comfort system we sell. We can’t do that if you install it.

No. PlumbLine stands behind every comfort system we install. We can’t do that without the support of the manufacturer, and a clear history of the equipment we are installing.
