Q: |

A: |
If you have just had renovations done, you should get the ducts cleaned as soon as the job is complete to eliminate all of the dirt, sawdust, etc. from your ducts. |

Q: |
How often should I change my air filters? |
| |
A: |
The most important factor for efficient operation of your heating and air conditioning system is proper airflow. Dirty air filters will severely limit airflow, which can cause the compressor to run continuously – causing your operating costs to increase. We recommend the your air filters be replaced a minimum of 4 times per year. Certain applications may require more frequent cycles. |

Q: |
How effective are HEPA filter systems? |

Q: |
Why does our furnace smell badly when we first turn it on? |
| |
A: |
A bad smell is usually the result of not using the gas furnace very often, which allows dust to settle on the heat exchanger. Then, when the furnace is turned on, the dust is burnt off – producing the bad smell. If you still have this problem even when the furnace is in regular use, consider replacing a filter in your system to prevent excess dust buildup. |

Q: |
What does it mean when a product is “ENERGY STAR qualified”? |
| |
A: |
If a product is ENERGY STAR qualified, this means that it is significantly more energy efficient than required under current federal standards. For example, central air conditioning systems with ENERGY STAR endorsed logos exceed existing federal standards by a minimum of 20 percent, while furnaces with the logo exceed minimum standards by at least 15 percent. Essentially, being ENERGY STAR qualified means that the products have a higher level of energy efficiency than standard products found on the market today.
ENERGY STAR qualified products allow homeowners to use energy more efficiently, save money on utility bills, help make their homes more comfortable and reduce air pollution.

Q: |
Since they cost a lot more than regular systems, what are the advantages of buying high-efficiency furnace or air conditioning systems? |
| |
A: |
Although it will cost more initially, buying a high-efficiency furnace, air conditioner or heat pump is an economically and environmentally responsible decision. Equipment with high efficiency ratings will:
- Use less energy, which helps conserve non-renewable resources and reduces greenhouse gas emissions;
- Pay for itself many times over as it accumulates savings over its lifetime from lower energy use;
- Cost less to operate thanks to more efficient motors and fans than standard HVAC systems;
- Often have a longer and more comprehensive warranty.

Q: |
Is a DC (ECM) motor really that much better than an AC motor? |

Q: |
What is carbon monoxide? |
| |
A: |
Carbon monoxide (CO) is a poisonous gas that you cannot see, smell or taste. It is produced by the incomplete burning of fuels such as natural gas, propane, heating oil, kerosene, coal, charcoal or wood. Improperly installed or poorly maintained appliances that run on these fuels may create unsafe levels of CO.
Exposure to carbon monoxide can cause flu-like symptoms such as headaches, nausea, dizziness, burning eyes, confusion, drowsiness and even loss of consciousness. In very severe cases, CO poisoning can cause brain damage and death.
CO warning signs include:
- A sharp, penetrating odour when your gas furnace or other fuel-burning appliance turns on;
- The air feels stale or stuffy;
- The pilot light of your furnace goes out;
- Chalky, white powder forms on the chimney/exhaust vent pipe or soot builds up around the exhaust vent;
- Excessive moisture forms on windows and walls;
- Unusual headaches, muscle tightness, disorientation and tiredness.
While CO detectors can warn you about sudden failures of your fuel-burning appliances, they are not a substitute for regular furnace care and maintenance.
