Q:  What is a heat pump?

A heat pump is a HVAC compressor that cools outside and heats inside. The unit has a reversing valve that changes the direction of the freon flow. It is cheaper to operate than a resistive heating circuit alone.

Q:  How often does my system need check-ups?

Most manufacturers recommend that even a new unit be checked twice a year. When we check your unit we will verify all factors that may effect the units energy efficiency including freon levels, motor conditions, thermostat calibration and coil cleanliness ensuring the safe operation of your unit.

Q:  How does my heat pump / air conditioner lose freon?

Constant vibration and age can cause leaks to develop in the refrigerant lines of your unit. When we check your unit we will measure the freon pressure to see if any has leaked and visually check the lines for noticeable leaks. A unit running low on freon will increase its running time and cause increased utility bills.

Q:  What is carbon monoxide?

Carbon monoxide is a colorless, odorless gas that is created from incomplete combustion of fossil fuel. If inhaled, carbon monoxide can cause illness or death. At levels up to 35 ppm carbon monoxide can cause headaches, dizziness, nausea, and fatigue. At levels over 200 ppm, carbon monoxide can cause death. We will check for carbon monoxide when servicing your furnace.

Q:  What would cause my furnace to put out carbon monoxide?

The dirtier the furnace burners are the more carbon monoxide will be produced. Normally these gases are vented through the flue pipe. If there is a crack in the heat exchanger (which can happen with age) then these dangerous gases can be blown into the home.

Q:  What if my furnace has a natural gas leak?

With time, a cock value, flexible gas line or gas line inside your furnace can get a leak. A natural gas leak is extremely dangerous, needing only one spark to cause an explosion or fire. We will check for natural gas leaks when servicing your furnace.

Q:  What is “sick building syndrome”?

Sick building syndrome (SBS) is diagnosed when 20%, or more, of the population of a building complains about problems such as headaches, shortness of breath, fatigue, nausea, dizziness, and eye or throat irritation. Studies show that roughly 20% of all buildings suffer from SBS.

Q:  Are ozone / negative ion air purifiers more effective than HEPA filters?

Yes. Negative ions and ozone can remove smaller particles from the air than HEPA filters can.
