Why is the upstairs of my house always hotter in summer & cooler in the winter when I have one unit?

Heat rises, thus the reason it’s hotter in the summer. Assuming the system was sized and installed correctly, you should consider installing a zone system if possible. Sometimes the addition of return air ductwork will help improve air movement and help make upper levels more comfortable.

I have friends and relatives that have installed UV lights on their furnace. What are they for?

UV is the abbreviation for ultraviolet. Located in the return air ductwork and by the indoor cooling coil, the ultraviolet air treatment system continuously emits high – intensity ultraviolet (UV) energy.

What should I do in case of an emergency like water dripping from my ceiling?

The first thing you should remember is that safety comes first. If there are any electrical appliances nearby, turn the electricity off at the main breaker.

Why do I have hot water in my toilet?

You may have hot water in your toilet because of a bad flapper in the toilet tank or a bad fill valve.

My furnace and air conditioner are both new, do I really need to have it cleaned?

Yes!! Even though your system is new, it still needs to have annual maintenance performed. This will help keep the warranty in effect.

What is a vent and what does it do?

Vents are the pipes (about 12” high) that stick out of your roof. Vents are necessary to vent sewer gasses outside of the home. You can think of a vent pipe like a straw.

During the winter my heat pump on my unit shuts off then restarts with a puff of smoke. Whats wrong?

Nothing is wrong with your unit. What appears to be smoke is steam from the outdoor coil after it completes a defrost cycle. After extended run times the outdoor unit will start to build frost or ice on the coil. The system is designed to go in a defrost mode when needed to clear the ice away and keep the efficiency level up.

What’s that black stuff on my ceilings and vents?

Burning candles can be the culprit for the black on your walls and ceilings as well as polluting the air your family breathes.

Should I be concerned about carbon monoxide?

Carbon monoxide, also known as the silent killer, can pose a serious threat in some instances and is yet another reason to have your furnace and water heater inspected by Williams Comfort Air.

Should I get my ducts cleaned?

Cleaning your ducts may be beneficial in improving your indoor air quality. A premium whole house duct cleaning will help decrease the spread of contaminates in your ductwork and home.

What does SEER and AFUE mean?

SEER stands for “Seasonal Energy Efficiency Ratio”. Basically it tells you how efficiently it converts electricity to cooling comfort.

How important is an air filter in my heating and cooling system?

It’s a fact: the trapped air we breathe in our homes can be loaded with dust, pollen, plant spores, and other pollutant particles. In many cases, it’s worse than the air outside.

How important is adding humidity to my home?

As we heat our homes, the air has a tendency to dry out. This dry air can damage the woodwork and furniture you have in your home as well as zap the moisture from our skin.
