FAQs
Here are the most frequently asked questions and answers from our "Ask an Expert" for Heating & Cooling. These should help get you started or may answer your questions too.
Question: How important is an air filter in my cooling and heating system?
Answer: 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.
Question: After my air conditioner runs for a while, ice forms on the big pipe outside and it stops cooling. What could be the problem?
Answer: More than likely, it’s either low on refrigerant or low on airflow. As a homeowner, replace your filter and allow the unit to thaw out. If the problem reoccurs, call Williams Comfort Air to schedule service on your system. We recommend having annual maintenance performed to keep your systems in peak operating conditions. Ask your Williams Comfort Air representative about our energy saving maintenance agreement program.
Question: How big of a furnace or air conditioner do I need for my home?
Answer: The only way to size an air conditioner or furnace for your home is to do a heat load calculation. The capacity needed is based upon how quickly your home gains or loses heat, not by square footage alone. ACCA's Manual J is an industry-approved method that Williams Comfort Air uses to insure the proper system is selected for you.
Question: What does SEER and AFUE mean?
Answer: SEER stands for “Seasonal Energy Efficiency Ratio”. Basically it tells you how efficiently it converts electricity to cooling comfort. The higher the SEER rating, the more efficient the system. By federal law all units sold must be a 13 SEER or higher. Williams Comfort Air recommends having a Comfort Consultant to come to your home and perform a heat load calculation to insure the proper size unit is installed. This is a free service to our customers that may help you save money and increase your indoor comfort.
AFUE stands for “Annual Fuel Utilization Efficiency”. This rating tells you how much of your heating dollars are converted to heat energy put into your home and how much is lost up the flue pipe. Most older furnaces are 50% to 60% efficient. That means that for every dollar you spend for gas from your utility company, $.40 to $.50 cents are being sent up the flue pipe to the outdoors. Federal law mandates that all furnaces being produced today be at least 80% efficient. Williams Comfort Air offers several different sizes of furnaces up to 96% efficient. That means that for every dollar you spend on gas from the utility company $.96 is converted to heat your home and only $.04 is sent out the flue pipe.
A Williams Comfort Air Comfort Consultant can visit your home, perform a heat load calculation and recommend the proper system to keep you comfortable and save you money. In many cases homeowners have saved enough on their utility bills to more than cover the investment of a new comfort system.
Question: Why is the upstairs of my house always hotter in summer and cooler in the winter when I only have one unit? What should I do?
Answer: 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.
Question: Should I get my ducts cleaned?
Answer: 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. New construction homes can benefit from having the ductwork cleaned to remove drywall dust, sawdust and other debris from the construction process.
Question: What's that black stuff on my ceilings and vents?
Answer: Burning candles can be the culprit for the black on your walls and ceilings as well as polluting the air your family breathes. Keep wicks trimmed to no longer than 1/4th of an inch to help reduce soot from the candles.
Question: Should I be concerned about carbon monoxide?
Answer: 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. A carbon monoxide detector is a wise investment. Williams Comfort Air offers a high quality carbon monoxide detector that has a 5-year warranty.
Question: During the winter the fan occasionally shuts off on my heat pump outside unit, then restarts with a big puff of smoke. What is wrong with it?
Answer: 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.
Question: I have friends and relatives that have installed UV lights on their furnace. What are they for and why do I need one?
Answer: 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. The energy eliminates (kills) a very high percentage of airborne bacteria and germs passing over the UV light field inside the ductwork. The UV light mounted next to the indoor cooling coil will help eliminate the growth of mold, mildew and other contaminates from the drain pan and coil surface. At Williams Comfort Air, we recommend installing non-ozone-producing UV products.
Question: My furnace and air conditioner are both new, do I really need to have them cleaned?
Answer: Yes!! Even though your system is new, it still needs to have annual maintenance performed. This will help keep the warranty in effect. Most all equipment manufacturs state in the terms of their warranty that annual maintenance must be performed by a qualified technician. Keeping your system maintained will give you assurance that it is operating at peak efficiency and safety.
Question: What is a vent and what does it do?
Answer: 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. When you put your thumb over the end of a straw, you can pull liquid up from the cup. What happens when you remove your thumb? The liquid drains out and the straw fills with air. Similarly, when liquid goes down a pipe, air needs to follow it. This air is pulled from the vent pipe. Without a vent pipe, the liquid will try to pull air through the P-traps on plumbing fixtures such as your tub and sink! If this happens, you’ll know from the smell! Likewise, without a vent, draining one fixture may cause another fixture in the house to back up!
