Most people don't realize their furnace and air conditioner run more and start and stop more than their automobile. Routine service is very important for energy efficiency and longevity of your equipment. Equipment that is not regularly serviced tends to need more repairs. We recommend having your system professionally cleaned and serviced a minimum of once per year.  

Yes, they can be serviced at the same time which could save an additional trip. The best months to do a combined service are March through October. Your central air conditioning system cannot be properly serviced in cold weather.

Check and make sure that the batteries are good, if your thermostat requires them. An adult should try turning the thermostat to the off position and back on to reset the system. If there are still problems, call your heating and air contractor.  

No. Your system was designed to provide a designated amount of air throughout the home. By shutting down some registers, you can cause a lot of damage to your furnace or central air conditioner.

Verify that it is the carbon monoxide warning and not a low battery warning. Turn off all gas appliances, if possible. Open a window or door for ventilation and call your heating and air contractor.  

The most commonly used refrigerant in today's air conditioners and heat pumps is R22. By 2010, all new air conditioners and heat pumps will be required to use environmentally sound refrigerant, such as R410A. This phase-out has been mandated in an effort to help protect the earth's ozone layer. The phase-out of R22 refrigerant will likely cause a significant increase in the cost of R22. York's R410A refrigerant meets the 2010 standards for ozone depleting refrigerants.  

SEER is the acronym for Seasonal Energy Efficiency Ratio. The SEER rating is shown as a number, example 13. The higher the number is, the more efficient the air conditioner. For many homeowners a 13 SEER (as of January 23, 2006, the minimum standard allowed by U.S. Department of Energy) air conditioner or heat pump will represent money saved on each month's electric bill. Exactly how much you can save will depend on the efficiency of your current system. Here is a comparison: 13 SEER efficiency -
*Delivers about 23% energy savings compared to 10 SEER models.
*Delivers about 8% energy savings compared to 12 SEER models. Actual savings will depend on the age, efficiency, and condition of the unit being replaced.  

AFUE is the acronym for Annual Fuel Utilization Efficiency.
AFUE is shown as a percentage 92% or 93%. The higher the percentage is the more efficient the furnace.  

Geothermal systems transfer heat from a building to the earth in the cooling mode, or from the earth to the building in the heating mode. Water is used as the heat transfer medium in a closed loop system. By using this stable thermal source, Geothermal heat pumps provide energy efficient comfort year round.  

Geothermal heat pumps also provide higher comfort levels than traditional space conditioning equipment. By using a relatively warm source of heat such as the earth, supply air temperatures are significantly higher in the heating mode than traditional air source heat pumps. Geothermal heat pumps also cycle much less often than fossil furnaces, creating a consistent indoor temperature with comfortable relative humidity.  

These systems have caught the eye of government agencies such as the Environmental Protection Agency (EPA) and the Department of Energy (DOE). Because it is lowest in carbon monoxide emissions, Geothermal technology provides a solution to global warming by primarily using the natural energy of the earth. Traditional space conditioning systems depend upon the exploitation and burning of fossil energy sources with the resultant greenhouse gas emissions.  

Low life cycle costs are provided by the low operating and maintenance costs of Geothermal systems, even when the higher initial installation costs are considered.
