FREQUENTLY ASKED QUESTIONS

.
COOLING
Q. The air coming out is not cool?
A. Check your breaker or fuses to confirm that power is getting to the condenser. Make sure the thermostat is set to cool and that the temperature is set as low or lower than the room temperature. The unit may be iced up and air cannot flow through it.  A clogged air filter or low coolant can cause this problem. Great Works can easily check and fix your system’s Freon or Puron level.

Q. What Is R-410A?
A. R-410A is an environmentally friendly, next-generation refrigerant. Many refrigerants developed before R-410A contains chlorine, which is harmful to the ozone layer.

R-410A is chlorine-free and therefore better for the environment. In fact, the Clean Air Act requires that as of 2010, all new air conditioning and heat pump units manufactured in North America will use chlorine-free refrigerants. So by choosing an R-410A air conditioner or heat pump, you’re getting the latest in refrigerant technology and helping the environment!

Q. It appears that my A/C unit is iced up.
A. This may be because you have dirty filters, the filter was removed or not installed properly. Filters should be replaced or cleaned every one to three months. Or your system may be low on coolant.

Q. My A/C unit is leaking.
A. Often your A/C will leak because of a clogged condensation drain. The condensation drain needs to be cleared. Sometimes this problem occurs when your unit becomes iced up then thaws. If you are not sure of what you are doing, do not attempt to fix the problem yourself. High voltage and other dangers are present. Call Great Works for professional repair. We are not responsible for accidents that may occur due to do-it-yourself repairs.

Q. How do I know what size A/C unit I need?
A. It depends. Homes with poor insulation or many windows may require a higher capacity A/C system. New homes that are tight and well insulated may need less. Call Great Works and allow us to make a professional recommendation.

Q. Should I turn off my thermostat during the day to save on my electric bill?
A. This is not wise. The energy that it takes for your system to “rebound” outweighs any savings. The best advice: a programmable thermostat!

HEATING
Q. My heat is not working.
A. Make sure the thermostat is set higher than the room temperature in order to call for heat. Other problems may be: Circuit breaker or fuse controlling the furnace is tripped or blown. Natural gas valve is closed. Pilot light is out. In all cases, if you cannot solve the problem call for a Great Works heating professional.

Q. The air coming from our vents is not warm.
A. The problem may be a dirty filter. A dirty furnace filter can restrict airflow and increase energy use in your home. Keeping your furnace clean lubricated and properly adjusted can save about 5% percent on heating costs. Or the gas burners may be dirty or need adjustment. Or you may need a new thermostat. Let the professionals at Great Works apply the best solution.

Q. The pilot light is out or goes out frequently.
A. Here’s what you should know: The burner in your gas furnace is ignited by electronic ignition as found in most modern furnaces or with a pilot flame common in older style furnaces. The gas furnace standing pilot (flame is lit all the time) is often referred to as a pilot light but regardless what you call it, its main purpose is to serve as a small ignition flame for the gas burner. When this small flame fails to operate properly or goes out it’s one of the most common reasons a gas furnace will fail to operate. The most common causes for the pilot light to go out are: a strong draft, dirty orifice or dirt in the gas tube. The thermocouple may also be faulty and is shutting off the gas supply. Turn to the professionals at Great Works to fix the problem.

Q. Is regular maintenance important?
A. Yes. Your heating and A/C system will not operate to its potential (or at all) if a component is not working in harmony with the system. Seasonal maintenance and inspections are critical because they identify problems and even dangerous conditions.

Q. What is AFUE?
A. AFUE stands for “Annual Fuel Utilization Efficiency.” A rating is assigned to every furnace using a formula based upon fuel use, electricity use and the fans used in the furnace. The higher the rating the more energy efficiency and savings on energy bills.

Q. What causes certain cracks to form in a furnace’s heat exchanger?
A. Repeated heating and cooling causes expansion and contraction of the metal. Cracks may form in the weaker areas of the heat exchanger.

Q. How often should I change my filter?
A. Disposable filters should be changed monthly. Filters are made with different efficiencies and thickness. A better filter simply works better.
